Изобретение относитс к области сельскохоз йственного машиностроени , в частности к устройствам дл агрегатировани сельскохоз йственных машин с трактором.The invention relates to the field of agricultural engineering, in particular, to devices for the aggregation of agricultural machines with a tractor.

Известна сцепка дл соединени трех сельскохоз йственных машин с трактором Ц, Данна сцепка содержит центральные и боковые брусь с сс1моустанавливающимис колёсами, св занное с центральным брусом прицепное устройство и транспортный прицеп. Центральный брус выполнен телескопическим, а боковые брусь в виде двух балок, шарнирно соединенных между собой с обеими част ми центрального бруса. При этом боковые брусь шарнирно соединены между собой и с обеими част ми центрального бруса.A known hitch for connecting three agricultural machines with a tractor C, this hitch comprises center and side bars with cusmo-mounted wheels, a hitch attached to the center bar and a transport trailer. The central bar is made telescopic, and the side bars are in the form of two beams pivotally interconnected with both parts of the central bar. In this case, the side bars are pivotally connected to each other and to both parts of the central beam.

Из рабочего в транспортное положение сцепка переводитс задвижением ползуна в брус с последующей его фиксацией, при этом боковые брусь складываютс .From the working to the transport position, the hitch is transferred by sliding the slider into a cant with its subsequent fixation, with the side bars folded.

Недостатком такойсцепки вл етс то, что при перевЪде агрегата из рабочегоположени д транспортное, и наоборот, трактор отсоедин етс от ползуна и присоедин етс к транспортному прицепу, на что необходимы дополнительные затраты труда. Кроме этого, в транспортном положении агрегат имеет большие габариты.The disadvantage of such a coupling is that when the unit is transferred from the working position of the vehicle and vice versa, the tractor is disconnected from the slide and attached to the transport trailer, which requires additional labor costs. In addition, in the transport position, the unit has large dimensions.

Наиболее близким техническим решением к изобретению вл етс прицепна сцепка, содержаща раму, выполненную в виде изогнутых в вертикальной { плоскости брусьев с опорны10 ми колесами, и сницу с поперечньм брусом 2. Однако необходимо выполнение вручную значительного объема работ при переводе агрегата из рабочего положени в транспортное, и The closest technical solution to the invention is a trailer hitch comprising a frame made in the form of curved bars in the vertical plane with support wheels, and a bar with a crossbar 2. However, a considerable amount of work must be done manually when transferring the unit from its working position to transport position. and

15 наоборот, включающее отсоединение раст жек от продольных брусьев или их фиксаци , поворот концевых уширителей и снкщл с поперечньви брусом. Транспортна ширина агрегата состав20 л ет 1,5 и более ширины одной агрегатируемой сельскохоз йственной машины .15 on the contrary, including the detachment of the extensions from the longitudinal bars or their fixation, rotation of the end spreaders and removal of the crossbar with the crossbar. The transport width of the aggregate is 20 lt 1.5 or more widths of one agricultural machine aggregated.

Целью изобретени вл етс обеспечение перевода сцепки из одного The aim of the invention is to provide a transfer of the coupling from one

25 положени в другое без затрат ручного труда.25 position to another without the cost of manual labor.

Это достигаетс тем, что предлагаема прицепна сцепка снабжена гидроцилиндром, которые установлены This is achieved by the fact that the proposed trailer hitch is equipped with a hydraulic cylinder, which are mounted

Claims

30 on the transverse beam and coupling elements, and the frame is made in the form of a hinge parallelogram, the front hinge is fixed on the transverse beam in the course of its movement, while the other hinges have coupling elements, while the front and rear hinges are located on the hitch symmetry axis. Figure 1 shows the proposed coupling in the transport position, side view; in Fig. 2, the same top view of Fig. 3 shows a hitch in the working position, a top view; figure 4 - section aa in figure 3. The hitch contains a draw 1, a transverse beam 2, a frame 3 in the form of a hinged parallelogram consisting of front 4 and 5 and rear: 6 and 7 bars, with bars 5-7 bent in a vertical plane; hinges 8-10 with coupling devices 11, supporting brackets 12, front hinge 13 of the frame connected to the crossbar. The transverse bar is fitted with hydraulic cylinders 14 and 15 connected to the front bars of frame 4 and 5, which are locked by retainer 16. Front hinge 13 and rear hinge 10 are located along the axis of symmetry of the tractor. To move the hitch to the transport position, you must unlock latch 16 and drive forward. In this case, the hydraulic cylinders 14 and 15 are in a floating position, i.e. There is no oil pressure in both cavities of the cylinders. The bars 4-7 are folded to the straight line position, and the agricultural machines 17 are arranged one behind the other. To transfer the hitch, from the transport position to the working position, it is necessary to turn on the hydraulic cylinders on the retraction of the rods and drive forward to lock the lock. Similarly, you can change the width of the coupling with the measurement of the width of the grip of machine guns. Claim linkage, comprising a frame made in the form of vertical bars curved with support wheels and a cross-bar link, characterized in that, in order to ensure that the linkage moves from one position to another without the cost of manual labor, the linkage equipped with hydraulic cylinders, which are mounted on the transverse beam, and coupling elements, and the frame is made in the form of a hinged parallelogram, forward, in the direction of travel, the hinge of which is fixed Hai to the transverse beam, and in the rest, mounted coupling elements, while the front and rear hinges are located on the axis of symmetry of the hitch.
