Coupling SG-18 (Modified) LLC PKF "Vyatka-Agrodizel", being a leading manufacturer of trailed tillage and forest equipment in the Kirov region, represents a new product that has no analogues on the market - the Hydraulic Circuit of SG-18 modified with an increased width of the location of transport wheels and increased width of the central swivel beam. On a row with other high-tech products manufactured by the company, such as Hydraulic CG-10, SG-12, SG-14, SG-15, SG-16, SG-21, SG-25 Coupling SG-18 Modified has a number of additional benefits: Modular design Increased stability during transportation Reduction of loads on the trailer trailer device When working the possibility of manufacturing a central swivel beam wide within 2.5-6.5 m with an increase in the width of the transport wheels. The modular design of the hitch allows you to provide convenient delivery to the consumer by road companies and railway transport. The presence of cylindrical locks in the pairing places of the coupling modules ensures accuracy and quality of the hitch assembly in the working position. The stability of the coupling is ensured by increasing the width of the central transport wheels, as a result of which the hitch passes through the field relief with less wrapping moments. This is especially true when using the coupling in the two trace option, when the center of the coupling mass is higher in relation to one trace option. The increase in the width of the bottom allows you to achieve greater snap-down stability during transportation, as well as reduce the load on the side bars of the hitch in the working position. In addition, the increase in the reduction width allows you to reduce the variable lateral loads on the tractor trailer. In coordination with the consumer, the company has the ability to make the width of the central part of the bottom in the range from 2.5 to 6.5 m without reducing product quality. Couplings with a width of the bottom of more than 4.5 m are recommended for those farms that are not used during the transportation of the coupling to the soil places common useAs a result, there is no need to obtain special permits. All products manufactured at the enterprise are undergoing a multi-stage control procedure, with the requirements for welding, painting, storage and packaging. All newly created products are undergoing government tests based on the FGBU MIS Kirov region and other regions of the Russian Federation, based on the results of which are positive conclusions about working capacity and quality. Quality stability and compliance with the standards of manufacturing equipment are also confirmed by the presence of certificates of conformity for all products of PKF Vyatka-Agrodizel LLC.
Coupling agricultural machinery
The seizure of most agricultural machines is 2-4 m, which provides better copying of the relief irregularities of various zone conditions. To increase the performance of the aggregates and the more complete loading of the engine and the implementation of the tractor tractor's tractor capabilities, several machines should be attached to it. Special coupling devicesAllowing such an attachment is called coupling. Using the hitch, the units are simple, consisting of homogeneous machines and perform one technological operation, and combined, consisting of heterogeneous machines that simultaneously perform several technological operations.
Improving the efficiency of using tractors depends on the presence of the required types of coupling.
The design of the coupling should provide:
a) the creation for each machine the same normal conditions for execution technological processes, as well as for a single working machine (without a hitch);
b) ease of movement of the unit when turning, a small width of the rotary band and a smaller length of idle races is possible;
c) strength and reliability with optimal mass of construction;
d) good adaptability to relief irregularities, which is especially important for wide-grapped units;
e) the convenience of the recruitment of the unit and its maintenance;
e) the simplicity and convenience of attaching or hanging the hitch to the tractor, the ease and speed of translation into the transport position;
g) the possibility of attaching such a number of machines that fully loads the tractor in the traction force with the speed of the forward movement selected from the conditions of the agricultural engineering conditions.
Our industry produces several types of coupling. Many clutch designs make gearboxes on the ground.
According to the attachment method to the tractor, the hitch is divided into trailed, attached and semi-mounted. According to the degree of versatility - to universal, allowing to attach various symmetric machines (cultivators, seeders, harrows, etc.) into one or two rows, and special, intended for attaching a certain type of asymmetric machines, such as plows and lemmylifts. According to the frame design, the knobs are distinguished with a rigid frame, with hinged and frameless. Figure 27 shows the main types of coupling manufactured by industry.
Fig. 1. The main types of coupling.
The length of the hitch check-out affects the path of the tractor along the swivel strip (abroad of the control line) before the rotation of the unit.
The specific coupling resistance is the effort required for its movement, entering the capture meter.
Currently, the greatest spread, especially in the steppe spaces of the south-east of the country, Ukraine, Kazakhstan and Siberia, received C-11U. With it, it is equipped with wide-graffit-four-four-step, two-three-three-tie aggregates with tractors DT-75, T-74, DT-75M, T-150 and T-4A.
The C-18U hitch is used for the recruitment of wide-grade harrow sowing (of 5-b seeders) and cultivator (of 4-5 cultivators) of aggregates with T-4A tractors, T-100M and T-130.
One of the shortcomings of the C-11U and C-18U hitch is the lack of devices for hydraulic control machines, which does not allow hydraulic equipment These tractors and reduce the number of service personnel.
Fig. 2. Hydrahed C-11u Hydraulic Coupling:
1 and 2 - metal pipes; 3 - transitional fittings; 4 fighters; 5 - Crosss.
The Red Star Plant has developed the design of the device to the C-11U clip for the hydraulic control of sub -48 grain seeders, SU-24 and KP-4 and KP-4M cultivators. This allows, for example, one tractor driver and one sownger to serve the unit from three seeders. The device consists of a seamless system metal pipes The outer diameter of 16 mm, transitional fittings, squares, crossbars, wooden stands with planks and stepladers and rubber high pressure hoses.
Pipes on the main timber are connected through crossbars, on side bars - coal and hoses, on the Snove- with the help of extension transitional fittings and hoses. The ends of the pipes are connected to the hydraulic tractor system through the transitional fittings and high pressure hoses. The collected pipes are placed in the slots of wooden supports installed on the bars and the coupling extension. Stands are fixed to the hitch of stepladers with clamping straps, and high-pressure hoses connecting the pipes of the main and lateral bar suspended on the racks.
Currently, the industry produces a hidrofy-11 hydrophic coupling.
On seeders and cultivators, aggregated with a hydraulic coupling, must be installed (if any) instead of conventional automata hydraulic dual-action cylinders.
Machines for the hitch are placed in one row (horren aggregation) if the driving wheels of the machines are installed not at the ends of the frame (SZP -24 seeders, SZP -3,6, CPG -4 cultivators); or in two rows (echelonized aggregation), if the driving wheels are located at the ends of the frame (SU-24 seeder, SUK -24, C3-3,6, Cultivators KP-4). Workers are included in the control line. With a horren-in aggregation, the working bodies of the machines should rise simultaneously, and with the echelonized working bodies of the second row machines should rise with delay.
In order for this delay, the second-rows machines are adjustable devices (type of the moderator valve). First rows are raised, then the oil pressure increases, the valve opens and lifts the second-row machines.
The CP-16 coupling is used for the recruitment of wide-grapped units with tractors Dt-75, T-74, T-150, T-4A, T-100M and T-130.ccheck consists of a central frame, right and left wings. The central frame is installed on two pneumatic supporting wheels. The side wings are connected to the central frame of articles, and their ends are based on self-aligning pneumatic wheels of the machine. In addition, the hitch has two extension cords with the same wheels. The working bodies of the machines rise and are lowered using the tractor hydraulic system.
With the help of the CP-16 coupling, one-stroke and echelonized units can be prepared. In the first case, the support wheels of trailed machines must be located inside the frame. Working machines with outdoor arrangement of wheels are located in two rows. The first row joins the traction bruster directly, the second row - with the help of extension cords.
The hitch is equipped with two hydraulic markers that control the tractor cab.
Currently, an automatic marker design has been developed. When you turn the unit on the rotary band going ahead, the marker unfolds into the working position, and the side marker, which was in the working position, moves forward for idling.
For the aggregate of three cars, markers remove the front part with the supporting wheel; The remaining part is fixed directly to the hitch.
With a working progress of a wide-graffit assembly, compiled using any trailed coupling, work machines are out of sight of the tractor driver, which causes the need even in the presence of hydraulic devices to have auxiliary workers to monitor the operation of the machines.
When turning such a bulky unit, you need to carefully monitor the movement of machines, not allowing the hitting them to each other (in order to exclude the breakdowns and the long-term downtime connected). All this leads to the need to rotate the unit at a slow speed and have a wide swivel strip.
In the fields with short gones, rugged terrain, with irrigation canals and forest belts around the edges, the use of wide-graffit-grazing units with trailed coupling is difficult. In this case, the farms should have maneuverable units with a possible approach of working machines to the tractor.
Such aggregates can be compiled using CH-75 semi-mounted couplings.

Fig. 4. CH-75 hitch nodes:
1 - the mechanism of hitch; 2 - bearing bars; 3 - lower strut; 4 - vertical frame; 5 - Kosyanka; 6 - reference wheel; 7 - Stretching.
The main parts of the hitch: side mechanisms of hits, bearing bars, horizontal frame (belt), vertical frame (arc), rear brackets, front and rear stretching, upper screed, lower strut and supporting self-aligning pneumatic wheels. The scheme of the unit with the DT-75 tractor and the KKPNA -3 cultivator is shown in Figure 5.
Fig. 5. CH-75 hitch aggregate scheme.
Recommended in the production of a universal trailed hydraulic coupling of SG-35, intended primarily for compiling aggregates with a seizure of up to 35 m from medium and heavy teeth BZS -1.0, BZTU -1.0, BZSS -1.0, BZTS -1, 0, Mesh harrow BS-2, Clay Broop SB-2.5, Ringattochpore Racing Ratops ZKK -6A, ZKVG -1.4 water rollers and towful seeders for working with tractors of tractors 3-5 vehicles.
With these compositions of the units, the coupling can be used on the harrowing of early Russian, under technical and other cultures, the harrowing of winter crops, on the removal and post-harvesting harrowing, rolling crops and making fertilizers by trailed towsers of RTT -4.2. The central part of the hitch can be aggregated with two cultivators and three grain seeders.
The sections are interconnected using two-axis joints and bypass frames, and with a trailer, it is reduced to traction adjustable in length.
On each bar of the section with the help of clamps, hard thrust for attaching seven teeth harrows and frames with chains are hinged; Chains are served to hang and hold the harrow in the transport position.
On the middle line, the bottom of the central section mounted a mechanism for lifting the harrow, which consists of a CSC-100 cylinder, oil pipelines, lever and stretch marks. When the cylinder is turned on, the lever moves; Stretching, associated with the central section, turns it, and the waterfront frames transmit a rotating moment to the other bars of the hitch. To work with hydraulic seeders and cultivators on the central section, a hydraulic guide is established consisting of two crosses, four oil pipelines, three CC-75 cylinders and 12 × 1400 twelve hoses.
The total coupling mass is 2540 kg, the coupling from one bar - 630 kg, and from three bars - 1550 kg.
The hydrocalized rise of the harrow when reversed at the ends of the gons, while moving or at stops, increases their service life and increases productivity. The individual trailer of the tooth sections provides a steady thread of the harrow, even on the chump fields, which creates conditions for increasing the working speeds of the unit and improve the quality of the harrow.
WG-35 wide-ailed coupling allows you to use powerful on harrowing crawler tractors at speeds up to 13 km / h; This increases labor productivity into one of the most stressful periods of work by 30-50%.

The bar of the same section, like the Snign, has a welded trailer 13 in the central part to attach guns. The ends of the bar have flanges, to which the prefixes 8 are fastened with ears-welded ears 9 to attach flexible stretch marks 5.
Depending on the number of aggregated guns on the bar and the consoles set trailers 10.
The discharge is made of angle 63x63x6 and serve to enhance the clutch bar in the horizontal plane. They welded the brackets for which they put the corner 6. To the corner with the help of leashes 12 and fingers, the tooth harons attach to the seal of the tractor trail.
Wheels are self-aligning. For stability of the stroke with a tight combination of agricultural tools with a hitch of the wheel plug, a pin is locked. With a horren-echelonized fork of wheels free.
With a passionate echelonized guns, an extension belongs a weld triangle, in the rear corner of which a glass of self-aligning wheel was welded with pneumatic tire 127 - 254 mm.
In the back of the extension, there is a trailer for attaching machines. To the frame frame, the extension can be fastened with two quick-consuming pins.
Marker (Fig. 2) Automatic, self-aligning: Changing the position of the left and right marker rods relative to the unit for the subsequent passage after turn does not require the intervention of the worker.
Each rod of the marker is a pipe that is one of the end, it relies on the bracket 5, installed on the seeder, and the other end through the tracking agent 8 mounted on the retractable tube relies on the soil.
The left and right hinged rods are connected to a chain 6 passing through the shock absorber 1 mounted on the bottom of the hitch. The chain length is calculated in such a way that when one trap is forms a trace on the unpersonal part of the field, the other is raised into a non-working position.
So that the hinges of the chain when turning the unit did not make dragged on the ground and could not get under the hitch wheels, the chain support bracket 3. Dual cable stretch 2 holds the chain in the bracket zone when the rod is inoperative.
A marker bar in a non-working position is held with a chain with double cable stretching and non-working stretching - cable. So that this stretching is not clinging for the protruding parts of the rod, the support for the cable 10 is provided.
When moving from the field on the field and the OSCEE of the rotary bands, both marker rods are translated into a non-working position. When moving to long distances, both marker rods are placed in the transport brackets 4 installed on the coupling.
Marker adjustment
Making sure that the seeders are aligned with respect to the hitch (with inconsistencies to stretch the unit for a certain distance, while the seeds do not occur the correct position relative to the hitch), they translate both rods into a non-working position. Adjusting the length of non-working cable stretch marks 9 (see Fig. 2) set the size of 200 mm from the center of the fork
before the extreme coulter.

The design of the hitch provides an individual attachment of each harrow to the bars of the central and side frames 1 (Fig. 12) by leashes 2, set at an angle of 15-200 to the surface of the field. This ensures the good stability of the boron stroke and exclude their incision on each other. Leashes together with chain stretching ensure the rise of the harrow when turning and in the transport position.
Translation of the coupling in the transport position
To transfer the hitch to the transport position (Fig. 13), disconnect the harrows 1 together with the leashes from the side frames and put them on the bottom of the hitch. Then disconnect the right crash 2 and telescopic separation 3. The harrows rise into the transport position with the rotation of the clutch bar on the 900 hydraulic cylinder and block in order to avoid spontaneous lowering. Feeding the tractor for ahead and left, the right bar 4 backs about 900 to the central bruus. Collections 3 are installed in the UCHO of the right bar and in the transport ear of the central bar. Similarly, left the left timber. After that, the hitch is ready for moving. When translating the hitch from the transport position in the working operations perform operations in the reverse order.
