By buying bread in the store, people are very often not even thinking about how difficult and responsible work is to grow this bread. Centuries go, and bread consistently occupies a dominant place in the food diet. How many expressions, aphorisms and wisdom are associated with this product. And today we will talk about one of the tools that plays a crucial role in the production of bread.
1. SK-3
Self-propelled combine, 3rd model. Soviet grain harvesting machine, which was created by GSKB for self-propelled grain combines and cotton cleaning machines in the city of Taganrog. He led the project Khanan Ilyich Izakson. The car was made from 1958 to 1964. A total of 169 thousand combines were created. It was the first Soviet combine equipped with a hydraulic strengthening of the steering wheel. SC-3 was also awarded the diploma of the Brussels Exhibition.
2. SK-4
Self-propelled combine, 4th model. As it is easy to guess, I came to replace the older model - SC-3. The car was produced from 1964 to 1974 at the Taganrog Combine Plant, as well as in Rostselmash. The grain harvesting machine received a premium of the Leipzig International Trade Fair, as well as the awards of exhibitions-fairs in Brno and Budapest. The collective-developer of the car under the leadership of H. I. Isakson was awarded the Lenin Prize.
3. SKD-6 "Sibiryak"
Double-drum-based Soviet Combine, which was produced from 1981 to 1984 at the Krasnoyarsk Combine Plant. The car was a product of deep modification of the SCD-5 "Sibiryak", which was produced since 1969 and despite the high reliability by the 80s of the 20th century, morally outdated. The car had a lot of "special" modifications, including for cleaning rice, work in areas without chernozem, a model with an extended rut.
4. Yenisei 1200.
Combine with the beautiful name "Yenisei" even young people should remember well from their childhood. The fact is that the release of the car began in 1985. The combine came to harvest a variety of crops, including sunflower, herbs, legumes and cereals. The car could also clean the culture in the "hard-to-reach" fields of the field.
5. DON-1500
Perhaps the most popular combine in the CIS after the collapse of the Soviet Union. The machine began to produce serially in 1986. For objective reasons, the car was used for a very long time in the former republics of the Union. The ubiquitous refusal of the combine harvester began only in 2006, when the more perfect imported and domestic models were hurried to replace him.
6. KSG-F-70
Very interesting sample. The Soviet combine on the tracked database, which was developed specifically for work on the rejected soils. For the most part, the car worked with feed crops: grass and corn. It was produced by the bin "Donselmash" in the city of Birobidzhan. Most such cars were in service with Far Eastern farms.
7. SK-5 "Niva"
The Soviet Combine, which was produced by the company "Rostselmash" from 1970. Development was led by Izakson Khanan Ilyich. The car is notable for the fact that it was able to become a business card of Soviet Combinoment. There is nothing surprising in this, the car was one of the most widespread in the USSR for all time.
In continuation of the topic, the story about and helped to promote science.
Today is the day of an employee of agriculture, so the time to write about any agricultural machinery - for example, about the combines. Recently, in the report, I mentioned a rare instance of the combine of the SCD-5 "Sibiryak". The same name, "Siberian", and the next model of the Krasnoyarsk Combine Plant - SCD-6, differing from its predecessor to another engine, a new spacious cabin and a number of other improvements. The industrial complex SCD-6 was not allowed, only 4 years old - from 1981 to 1985, and by now there are also not very much preserved, especially in working condition. This Combine of 1984 released on joke in one of the villages of the Sargatsky district, externally, almost complete, not counting the rear wheel, but at this place he stood for a long time, and left again on the field - unknown.
And this SKD-6 from Chapaevo is quite ready for the fight for the harvest when the snow melts. :) In the combine there is even a modern license plate "Tractor" type and inspection, the truth is overdue. By the way, in the Soviet times the number on the combines, unlike tractors, was not often set, and now the Gostakhnadzor follows this.
A big surprise for me was the discovery in 2009 in large uks of a rare caterpillar (!) Modifications "Siberian", wearing the index of the SCD-6P. The letter "P" means "rice plating", so the car and the tracked propeller - to work on the flooded rice fields. As such a combine hit the Omsk region - it is incomprehensible, perhaps it is associated with work on a wetland, our swamps in the north.
In 1985, the Krasnoyarsk Combine Plant moved to the release of a new model - "Yenisei-1200", the "Sibiryak" brand from that time was no longer used, but a variety of "Yenisei", including modern modifications of the 1200th model, the plant still produces.
Self-propelled, wheel, double-drum, is intended for cleaning grain spikes with direct and separate combine. Using additional devices, the combine can be removed the grain seeds, corn on grain and silage, sunflower, soy, legumes and cereal cultures. For cleaning the non-uninterested part of the crop, equipped with a digger. It consists of the harvested part (1), thump (with a thorough-duplex device, separating, cleansing and transporting devices (6)) of the bunker (4) with a unloading device, a motor installation, power transmission, chassis, cabin with a control platform, hydraulic system, Electrical equipment and alarm.
The harvested part includes a heter and an inclined camera, hung on the throat. The header housing is hinged on the inclined chamber at three points on the central spherical joint and two hinged pendants of the springs blocks and balanced by these springs. Due to this, the relief of the soil in the longitudinal and transverse directions is copied. The cutting machine, auger, reel and drive mechanisms of these working bodies are mounted on the header housing.
Motovilo universal, with an eccentric mechanism, spring fingers, riblin. Its drive is carried out by a two-circuit chain transmission from the upper pulp of the rotationality frequency variator.
The inclined camera consists of a housing and a chain-plate conveyor. The housing is hinged with the receiving chamber of the throat. The cutting apparatus has single steel forged fingers with naughty liners.
The threshold includes a receiving beater, a double-drumped threshing-separating device, straw-staining (7), cleaning, transporting devices, drives and mechanisms for adjusting the working bodies. The blades of the receiving bite are tangential.
The CCD-6 combine is significantly different from its predecessor. The capacity of the grain hopper is increased to 4.5 m3 and the top-end cleaning area. Engine power - 140 liters. from. (103 kW). The combine provides a convenient cabin.
The new modification of the combine "Sibiryak" under the brand of SCD-6AN is available in the configuration for the non-black-earth zone. This combine is a modification of the combine CCD-6 and has the following features:
the rack is equipped with an invaluable cutting apparatus, a rebels with hydraulic powder and spring fingers. Motovil support is curved so that when removing the rebellion, the fingers of the river fell below the line of the cutting apparatus by 50 mm;
installed an EMD-22 engine with a capacity of 103 kW (140 l. (c);
the bridge of the drive wheels MK-23 has a hydraulic engine from the MP-23 hydromotor with GOST-90 hydraulic pump;
the threshing drum is equipped with a reverse scrolling hydromechanism when driving;
installed on the lead bridge of the tire from the tractor K-700;
expanded control of controlled wheels;
at the cockpit installed sunscreen blinds.
Combine adjustment
Starting cleaning, it is necessary to assess the state of culture and, depending on the specific working conditions, it is pre-adjusted by the working bodies of the combine, using recommendations. After the passage of 50-100 meters, the combine should be stopped, check the quality of work and, if necessary, clarify individual adjustments.
Pre-adjustable harvesters and hamper hammers can in some cases work unsatisfactory due to a sharply changing state of Steblastowa, clogging, non-leveling of the field, etc. To further configure the combine, depending on the loss of grain and the quality of it in the bunker, use specific schemes. Changing the moisture content of the mass during the day causes the need for daily two-time migration of the combine: at 12-13 hours - on cleaning dry mass; In 17-18 hours - to work in the evening and morning hours of operation - to clean the moistened mass.
In seed sites, it is recommended to use combines that have removed at least 100 and not more than 350 hectares of grain. This will provide grain with the smallest percentage of crushing and micro-damage. For technological configuration of the combine harvesters, the "combiner bag" is produced, containing tools and devices, an additional configuration of working bodies, two determines of the operation modes of the CCD-5 combines and SC-5, SC-6 grain modifications and instructions for the use of the entire set.
Mode determinants contain information on pre-configuring combines. The determinant of the operating modes of the header and the hammers of the combine harvester consists of two external and one internal disks. In the inner disk on both sides, sectors applied to various states of Steblasta, and the numbers of adjusting parameters are applied: on the one hand - for the header, on the other - for the throat. The external disks indicate the names of the adjustment parameters corresponding to the numbers on the inner disk. In addition, there are additions on external disks to evaluate the cleaning conditions, the choice of the desired revolutions of the reel and the elevation of the apron over the straw-stroke, etc. Customize the combine on the determinant of the modes must be started with the header. First determine the yield of the bread mass and its condition, then the external disk with the receptments for the header is rotated so that the cutout of it coincides with the internal disk sector containing the status indicators of the Steelness state, select the preliminary values \u200b\u200bof the adjustment parameters (height and removal of the reel, gaps between the screw and the bottom of the header , Motoviller turns and the angle of inclination of the gravel) and adjust the tray accordingly.
The aligning cutout of an external disk with the corresponding internal disk sector is selected for the pre-adjustment for the threshing machine.
When configuring a two-drum threshing machine for harvesting grain spike crops, it is necessary to remember that the frequency of rotation of the first drum in normal conditions should be less than 150-200 min-1 than the second, and the threshing gaps are more than 2-4 mm.
Given the high level of yield, it is very important to combine separate cleaning with direct combinement. It is embarked on to mate breads in rolls when the moisture content of the grain is reduced to 35%. At 17-18% of grain moisture, separate cleaning is stopped and transferred to direct combine.
The combines must be adjusted so that the grain is not crushed during rapidness and was injured. It is especially important to take into account this when cleaning seed sections.
Repair of the bridges of the combine SKD-6
The main defects of the bridges
Main defects of the forefront of the forefront: Frames of parts, increased noise, separate knocks, increased heating during operation and disruption of adjustments due to wear of bearings and their seats (1), slotted, keypone and smooth moving compounds, disruption of rivet, bolted and other fixed compounds, as well as as a result of wear of antifriction linings, gears and bends of individual parts, wear axis and sleeve under this axis in the front axle beam, pins, pins and holes under them; wear of the shaft of the axial pin, the sleeves under the axis axis, landing places for bearings and bearings; Wear or damage to slots and threads. Wearing the front axle parts violates its adjustments, and the parts failure can lead to an accident.
The main defects of the rear axles: the rear axle, transverse thrust and swivel levers, the wear of the rear axle under the pivot, kkvornney and sleeves under the pokvorni (3), landing places under the bearings of the rotary pin, breaking the thread. Wearing the rear axle parts disrupts the installation of the rear wheels, increases one-sided wear of rubber on them and makes it difficult to control the car.
Premature wear of the rear axle parts is caused by untimely lubricant, driving at elevated speeds on an uneven road, improperly adjusting the couplings of rotation, conical gears and bearings, long-term work with an inadvertible load, the use of lubricants intended for this machine or not corresponding to the year.
Restoration of parts of the bridges
Disassemble the front bridges on special stands. Disassembly and detail defecting are the same as when repairing gearboxes. The restoration of the parts of the front axles is made up of individual operations depending on the nature of the defect. The body of the transmission or anterior bridge of the combine, cast usually from gray cast iron, can have the following defects: cracks, fesomas, wear and damage to the threaded holes, depreciation under bearings and nests or bearing glasses.
The housing is selected in emergency breaks, as well as depending on the defect, technological capabilities of repair and economic feasibility.
Cracks in the walls and the bottom, holes, as well as worn threaded holes, landing places for bearings and other defects are restored by the same techniques as during the repair of the gearbox cases. Carter of the front bridge of cars, is made of a forging cast iron or made of steel, has such defects: damage or wear of holes under the intersection centered bolts, bending of the casing of the semi-axes, depreciation under the outer and internal rings of bearings and seals under seals, internal and external sealing places . The damaged hole under the head of the central spring bolt is brewed, cleaned and drilled the hole of the normal size. Bridle covers rule under the press.
Planting places for inner rings of bearings and under the seal are applied, they are pulled and grind to normal size.
Worn seats under the outer rings of bearings in cast iron enclosures restore the setting of the sleeves, and the steel, in addition, the surfacing with subsequent processing into normal size.
Damaged outer threads on the casing of the semi-axis are applied and cut a new one. Worn washers under the rings of bearings and under the seal are restored by the surfacing, staging of the sleeve or distribution, followed by treatment under the nominal size. Holes with damaged threads under the fastening bolts of a glass of roller bearings or the gearbox housing are drilled using special fixtures and cut the threads of the increased size.
The details of the differential are the following main wear: landing space for the bearing, holes for the neck of the semi-axle, end and spherical surfaces under the seed gear of the satellite, holes of the bearings of the crossbar and under the coupling bolts in the a cup of differential, teeth, end surfaces and holes in satellites, sheek crossing, teeth and the end surfaces of the semi-axle gears (12).
The seating area under the bearing of the differential cup is set by distributing, surfacing, chromium or iron with subsequent treatment under the rated size. To avoid charging the differential cup (8) when surfacing, it is preheated.
The holes for the neck gear semi-axes are mounted, and the neck of these gears chrome and grind to obtain a normal clearance of 0.065 ... 0,165 mm.
Sometimes they are made on the contrary: the neck gears are grosted before the detection of traces of wear, and the holes of the differential cups restore the staging of the stuff from the material, similar to the material of the cup, and processed them until the required gap is obtained.
When wearing and jackets, the end surface under the semi-axis gear and spherical under the satellites is pulled to the removal of traces of wear and grind.
Cross bearings openings are deployed under an increased bearing size.
Holes for the bolts or rivets of fastening the slave gear are deployed under the increased size.
Satellites (11) and semi-axes gears (12) with worn teeth are selected. The damaged or worn-out end surface of the semi-axle gear and the spherical surface of the satellites is fluttered and grinding.
The worn holes of satellites (11) are grinding until traces of wear and obtaining proper geometric shape.
The axis or cervials are chrome and grind the size of the obtained holes in the satellites, creating the necessary gap, and in the holes of the differential cup, the tight fit.
The casters can be restored by the formulation of cementing sleeves, which are then ground under the size of the satellite holes. After grinding, all axis of the casket necks should lie in the same plane and be perpendicular to each other. Allowable deviation is 0.05 mm at extreme points. 280.
The semi-axes manufactured most often from alloyed steels of stamps 40HGTR, 40X, 35HGS, can have the following defects: slot wear, seats fashion bearings and seals, wear holes in the flange, bending.
The semi-axes are elevated at a break, cracks and wear of the slots to the sizes exceeding allowable, and automotive - with cracks and fragments of the flange.
Worn seals under seals and bearings, key grooves and slots are restored just like the shafts of gearboxes.
Worn holes in the semi-axis flange brew and drill new ones. Sometimes new holes are drilled between the latter without welding. Holes are drilled with a patch conductor and special fixture.
Running axes rule under the press.
The hubs of the front wheels of cars are made usually from the ductile cast iron K.Ch 35-10 or k.ch 37-12, have the following defects; Wearing nests under bearings, fastening the brake drum fastening flange, holes wear under the heels of fastening the wheels and threaded holes for heels or fastening bolts of the semi-axis. The hub is selected with cracks and breaks.
Worn nests for bearings restore the setting of the sleeves or weld and melted.
The hub flange warning for the brake drum fastening is eliminated by pulling using a special device.
Holes for heels fastening the wheels restore repair bushings. Damaged or torn threads in the holes for the heel or the fastening bolts of the semi-axis flange restore the formulation of threaded inserts (screwed) or drill holes between the conductor available through special devices and cut a new thread.
The shafts, axes and gears of the rear axles and transmissions have the same defects, restore them with the same techniques as similar parts of the gearboxes.
Restoring the details of the rear axles. The axis of the swing with one-sided wear is rotated 180 °, and when bilateral wear, they are applied and processed under normal or increased size. The hole under the axis is deployed to an increased size or restore the stitching of the sleeve. Planting places under the shaft sleeve axial axle are applied and processed under normal size.
Worn holes for pins and pins are deployed to an increased size and manufactured new pins and pins.
Planting places under the bearings of rotary axles are reduced by iron or applying the polymer elastomer. The worn slots of the rotary pin or the axial axle shafts are removed by plasma strings or vibrating surfacing, they are taking off and cut new ones. Putting the key is allowed instead of a slotted connection of rotary levers with pin. Cut rotary levers rule, and the levers with cracks are chosen.
The beam and twisting of the front axle are determined by various devices, templates, rules, coal. The axes are ruleled under the press in the cold state.
At specialized auto repair enterprises, the front axles check and rule on special stands. Before checking, restore axis platforms for the springs fastening. The area is welded and treated with an abrasive circle on a flexible shaft.
The axis with cracks is chosen. Powered holes with insignificant wear are deployed under an increased size, with great deposits they are cleared. In the bore holes, the bushings are pressed and they deploy them under normal size. The planting surfaces of the rotary pin for bearings are restored by chromium or iron, followed by grinding under normal size. It is allowed to restore electromechanical treatment with the use of additional material or without it, but without the processing of the poles. You can also restore landing places for bearings by applying the Elastomer GEN-150 (B) film. It is dangerous to use manual electric arc or other types of electric arc and gas surfacing, they lower the fatigue strength of the trough, which leads a breakdown and accident.
Worn sleeves are replaced by new ones. They are deployed perpendicular to the inner ends of the sleeves, ensuring the alignment of the holes. Press and deploy one sleeve inserting the scanning screen to the specially left of the old sleeve, then pressed and processed the second sleeve. When pressing, they monitor the combination of holes for lubrication. After processing, it is thoroughly cleaned from surface chips and oil groove sleeves.
Worn holes are deployed and increased by the outer diameter of the sleeve with a tension of 0.01 ... 0.1 mm.
The damaged threads of the shank of the axle are taking off and cut a new, repair size, or weld and cut the threads of normal size.
For a pivot (3) is characterized by wear of the outer surface under the sleeve. It is chrome and grind under normal or increased size.
Sometimes the pivotes are grinding before removing wear, and the bushings are deployed under the reduced size of the pivot.
Assembly and adjustment of bridges
The assembly and adjustment of the front bridge are carried out on the benchs for disassembly.
The front combine bridges are collected in such a sequence. The front axle put on the stand. Swivel levers are fixed in the rotary axles, the axes are installed on the axis and the transverse steering craving is mounted. Install support brake discs and brake pads. Putting brake drums and wheels assembly. Check the correctness of the wheel installation and adjust the angle of their convergence and the maximum rotation angle. A certain angle of the collapse of the front wheels and the angle of rotation of the pivota backwards are provided for by the design of the front axle and the rotary pin.

In pre-revolutionary Russia, there were no combines production. In the USSR K. appeared at the end of the 20s-early 30s. In 1930, the Communar Communar Combines began at the Zaporozhe Plant. In 1932, the production of these combines was organized in Saratov. In 1931-32, the production of trailed combine harvesters from C-1 began at the Rostselmash factory. They passed 2.5 kg of cereals in a second through the throat and cleaned, except grain, sunflower, corn, millet and other cultures. For the pre-war years, the combined plants of the USSR (mainly Rostselmash and Zaporizhia "Communar") were given to agriculture almost 200 thousand combines, which played a big role in the mechanization of harvesting.
The new powerful development of combinerness has reached the USSR after the Great Patriotic War of 1941-45. A clearer specialization of agricultural engineering factories was carried out; The main enterprise of Soviet Combinogenation became the Rostselmash plant, which produced C-6 trailed harvesters and RSM-8. From 1947 to 1956, at Taganrog, Tula and some other plants, self-propelled combines C-4 were manufactured, and in 1956-58 - modernized C-4M combines. In 1958, the Central Committee of the CPSU and the Council of Ministers of the USSR adopted a decree on the termination of the production of trailed combine harvesters and the organization of the issue of more productive self-propelled combines. By this time, the model of SK-Z self-propelled combine and production of combines began at the Rostselmash plant and the Taganrog Combine Plant. Since 1962, these plants began to produce self-propelled combines.
These were the most massive options:
1. SK-3
At one time he became a real breakthrough.
Self-propelled combine, 3rd model. Soviet grain harvesting machine, which was created by GSKB for self-propelled grain combines and cotton cleaning machines in the city of Taganrog. He led the project Khanan Ilyich Izakson. The car was made from 1958 to 1964. A total of 169 thousand combines were created. It was the first Soviet combine equipped with a hydraulic strengthening of the steering wheel. SC-3 was also awarded the diploma of the Brussels Exhibition.
2. SK-4
Received worldwide recognition.
Self-propelled combine, 4th model. As it is easy to guess, I came to replace the older model - SC-3. The car was produced from 1964 to 1974 at the Taganrog Combine Plant, as well as in Rostselmash. The grain harvesting machine received a premium of the Leipzig International Trade Fair, as well as the awards of exhibitions-fairs in Brno and Budapest. The collective-developer of the car under the leadership of H. I. Isakson was awarded the Lenin Prize.
3. SKD-6 "Sibiryak"
Excellent was a car.
Double-drum-based Soviet Combine, which was produced from 1981 to 1984 at the Krasnoyarsk Combine Plant. The car was a product of deep modification of the SCD-5 "Sibiryak", which was produced since 1969 and despite the high reliability by the 80s of the 20th century, morally outdated. The car had a lot of "special" modifications, including for cleaning rice, work in areas without chernozem, a model with an extended rut.
4. Yenisei 1200.
Reliable and endless cleaner.
Combine with the beautiful name "Yenisei" even young people should remember well from their childhood. The fact is that the release of the car began in 1985. The combine came to harvest a variety of crops, including sunflower, herbs, legumes and cereals. The car could also clean the culture in the "hard-to-reach" fields of the field.
5. DON-1500
This combine remembers each.
Perhaps the most popular combine in the CIS after the collapse of the Soviet Union. The machine began to produce serially in 1986. For objective reasons, the car was used for a very long time in the former republics of the Union. The ubiquitous refusal of the combine harvester began only in 2006, when the more perfect imported and domestic models were hurried to replace him.
6. KSG-F-70
Machine for working in difficult conditions.
Very interesting sample. The Soviet combine on the tracked database, which was developed specifically for work on the rejected soils. For the most part, the car worked with feed crops: grass and corn. It was produced by the bin "Donselmash" in the city of Birobidzhan. Most such cars were in service with Far Eastern farms.
7. SK-5 "Niva"
Self-propelled, wheel, double-drum, is intended for cleaning grain spikes with direct and separate combine. Using additional devices, the combine can be removed the grain seeds, corn on grain and silage, sunflower, soy, legumes and cereal cultures.

Molotinal drums - bleed. The technological process of threshing and separation in a two-drum thumberry occurs in two stages. The first step of the thread of the bread mass passes in the first threshing machine, the drum of which, with a reduced frequency of rotation and enlarged gaps between the beaches, the subbarabrays moves the most ripe, large and easily handy grain with minimal damage. The second stage proceeds in the second threshing machine, the drum of which works in a more rigid mode (an increased rotational speed and a smaller threshing clearance).
The frequency of rotation of the threshing drums is changed by a hydromechanical device. The first drum variator is located on the left side of the throat, the second right. The control of variasts is carried out by hydraulic cylinders from the combine workplace.
The threshing device is equipped with a reverse scrolling mechanism of the first drum. Solomotroat four-block. The separating surface of the first cascade of the straw-stroke keys is changed (in contrast to the SCD-6 straw-stroke keys).
The cleaning system includes a screen, a two-fold mill with an extension of the upper sieve and a fan. Blind gaps solves and extension cords, as well as the frequency of rotation of the winner of the fan are adjustable. In the combine (unlike CCD-6), a reinforced cleaning is installed. Includes new solutions, extension cord, changed rear suspension screen. The harvester hammer is equipped with a homeing device.
