(54) СЦЕПНОЕ УСТРОЙСТВО(54) COUPLER

II

Изобретение относитс к сельскохоз йCTBeHHotvry машиностроению, в частности к сцепным устройствам, преимущественно дл соединени трактора с сельскохоз йственной машиной.The invention relates to agricultural machinery and machine building industry, in particular to coupling devices, mainly for connecting a tractor with an agricultural machine.

Известно сцепное устройство, содержащее размещенный в задней части трактора посредством шарнирно закрепленной на нем штанги т говый крюк и дл взаимодействи с ним петлю, расположенную в передней части сельскохоз йственной машины 1.A coupling device is known, which contains a trailing hook placed at the rear of the tractor by means of a hinge attached to it and for engagement with it a loop located in the front part of the agricultural machine 1.

Однако известна сцепка имеет сложную конструкцию и недостаточно жесткую фиксацию крюка.However, the known hitch has a complex structure and insufficiently rigid fixation of the hook.

Цель изобретени - повышение надежности работы устройства путем обеспечени жесткой фиксации крюка.The purpose of the invention is to increase the reliability of the device by providing rigid fixation of the hook.

Эта цель достигаетс тем, что на штанге шарнирно закреплены рычаг с прорезью и фиксирующий элемент, палец которого размещен в прорези рычага, при этом рьгчаг посредством механизма его поворота соединен с трактором.This goal is achieved by the fact that a lever with a slot and a locking element, the finger of which is placed in the slot of the lever, is hinged on the rod, while the lever is connected to the tractor by means of its rotation mechanism.

На фиг. 1 изображено сцепное устройство в исходном положении; на фиг. 2 - то же, в момент начала сцепки; на фиг. 3 - то же, по окончании сцепки.FIG. 1 shows the hitch in the initial position; in fig. 2 - the same, at the moment of the beginning of the coupling; in fig. 3 - the same at the end of the coupling.

Сцепное устройство состоит из шарнирно установленной на задней части трактора 1 штанги 2, оканчивающейс крюком 3, рычага 4 с прорезью 5, в которой размещен с возможностью перемещени палец 6 фикса10 тора 7. Рычаг 4 и фиксатор 7 шарнирно закреплены на штанге 2. На передней части сельскохоз йственной машины 8 закреплена петл 9 дл взаимодействи с т говым крюком 3. Рычаг 4 соединен с трактором 1 по15 средством механизма его поворота, например гидроцилнндра 10. Фиксатор 7 соединен со штангой 2 посредством шарнира 11.The hitch consists of a hinge mounted on the rear of the tractor 1, a rod 2, ending with a hook 3, a lever 4 with a slot 5, in which the pin 6 of the fastener 7 is movable. The lever 4 and the clamp 7 are hinged on the rod 2. agricultural machine 8 is fixed loop 9 to interact with the trailing hook 3. The lever 4 is connected to the tractor 1 through 15 by means of a mechanism for its rotation, for example hydrocylindra 10. The latch 7 is connected to the rod 2 by means of a hinge 11.

Сцепное устройство работает следующим образом.The hitch works as follows.

Claims

In the position of the hitch shown in FIG. 1, the tractor operator switches on hydrocyles schr 10 to lower the lever 4. At the same time, the rod 2 is lowered, remaining through, the lock 7 suspended to the lever 4. Lowering is done until hook 3 enters the jawl of loop 9 and, subsequently does not lie on its surface. Upon further movement of the lever 4, when the tang 2 is stopped, the latch 7 rotates around the hinge 11, overlapping the hook 3 together with the loop 9 enveloped. In this position, the unit from tractor 1 and the agricultural machine 8 is ready for movement and maneuvers. When uncoupling, the hydraulic actuator O is switched on to rise. In this case, the latch 7 is rotated around the hinge 11, releasing the shed of the hook 3. The latch 7 is rotated until. until finger 6 rests on the edge of slot 5. In the distance, the first lift of lever 4 is performed together with the pivot arm 2 and the hook 3 comes out of the throat of the loop 9. Using the invention will increase the availability of the device and the safety of the tractor operator. Claim device, advantageously for connecting a tractor with an agricultural machine, comprising a trailing hook located at the rear of the tractor by means of a hinged bar and an interaction loop with it located at the front of the agricultural machine, characterized in that The goal is to increase the reliability of the device by providing a rigid fixation of the hook; a lever with a slot and a fixing element with a finger hinged on the rod is hinged; chaga, while the lever through the mechanism of its turns connected to the tractor.
