    The invention relates to agricultural machinery, in particular to tractor couplings.
    The purpose of the invention is to reduce the load on the device and reduce the size.
    Figure 1 shows the device, a general view; figure 2 - the same, bottom view.
    The device consists of elements connected to the tractor housing 1, comprising a rear axle 2, an axis 3 and a power take-off shaft 4. The attachment mechanism allows agricultural implements (not shown) to the housing 1 or to its frame to be attached to the tractor or another tractor.
    The fastening mechanism contains an ankle-and-5 section of an arm having a left 6 and right 7 vertically oriented sidewalls rigidly connected at the lower ends with a double lower part consisting of the upper 8 and lower 9 panels, in which two vertical holes | 10 for fasteners 11. The upper front portions of each sidewall 6 and 7 are pivotally connected by means of the left and right protrusions of the axis 3 through bearings (not shown). The lower front ends of the rocker arms 5 comprise left and right pivot bearings 12 and 13. Each pivot bearing 12 and 13 holds two spherical bearings of known construction. The left and right outer bearings pivotally connect the rocker to the front ends of the left 14 and right 15 lower arms. Q
    The curved rear ends of the sidewalls contain protruding horizontal supports 16 and -17, which engage with the levers 14 and 15, their stopper only
    Saw a turn outward of the lower lever or in the hole 23 to allow limited movement.
    Each spore 20 and 21 also holds the threaded rod and sleeve in order to ensure precise adjustment in length. A horizontal axis 24 extends both through the front ends of the lower arms 14 and 15 and the thrust 20 and 21. When the levers 14 and 15 are in the lower position, they do not cling to the stops 16 and 17. Instead, turn in the lower position These arms are limited to spacers 20 or 21, which transmit the swiveling forces of the rocker arm 5 and, in its turn, to the hinged support of axis 3.
    The left and right lift arms and 25 have front ends that are secured with linch pins at the respective left and right ends of axis 3 for rotation with it. The rear ends of the lift arms 18 and 25 are pivotally connected to the upper ends of the respective left and right posts 26 and 19. The lower ends of the posts 26 and 19 are connected to the lower arms 14 and One or both racks 26 and 19 can be replaced by hydraulic cylinders.
    The left 27 and right 28 lifting hydraulic cylinders are pivotally connected at one end with the projections 29 and 30 to the cusp 1. The ends of the lifting rods are guided by the cylinders 27 and 28 pivotally connected. with iodo-lift levers 18 and 25 so that the lifting cylinders are able to operate with a chain of rotation of the lifting levers and rotate the axle, thereby raising or lowering the lower lever and 14 and 1

The inner left and right bearings are pivotally connected to the arm and the front ends of the left 20 and right 21 struts. The rear end of each left 20 and right 21 spacers has an elongated hole (not shown) into which a finger is inserted, passed through one of the holes 22 and 23 in the central part of the respective lower arms 14 and 15.

    Each spore 20 and 21 also contains a threaded rod and sleeve in order to provide precise adjustment in length. The horizontal axis 24 passes through the front ends of the lower arms 14 and 15 and the struts 20 and 21. When the levers 14 and 15 are in the lower position, they do not engage the stops 16 and 17. Instead, the lower arms rotate in the lower position spacers 20 or 21, which transmit rotational forces of the rocker arm 5 and, in turn, to the hinge support axis 3.
    The left and right lift arms 18 and 25 have front ends that are secured with linch pins at the respective left and right ends of axis 3 for rotation with it. The rear ends of the lifting arms 18 and 25 are pivotally connected to the upper ends of the respective left and right posts 26 and 19. The lower ends of the posts 26 and 19 are pivotally connected to the lower arms 14 and 15. One or both racks 26 and 19 can be replaced by hydraulic cylinders.
    The left 27 and right 28 lifting cylinders are pivotally connected at one end to the projections 29 and 30 of the housing 1. The ends of the rods of the lifting hydraulic cylinders 27 and 28 are pivotally connected. with iodo-lift levers 18 and 25 so that the lifting cylinders can be actuated with a chain of turning the lifting levers and turning the axle, thereby raising or lowering the lower lever and 14 and 15.

    using a vertically oriented hitch pin 31, which forms the vertical axis of the hitch. The lower parts of the sidewalls 6 and 7 hold two horizontally arranged plates 32 and 33 with a series of holes, between which the rear end of the rod 11 is placed. Fingers can be inserted into the holes of the plates 32 and 33 to limit the horizontal movement of the rod 11. Three vertically arranged holes (not shown) are formed in the front part of the rod 11 so that through two holes 10

    in the yoke, the rod 11 could be pivotally connected to the terminal 5 in different positions to enable the length of the rod to be changed relative to the power take-off shaft without additional sections. In this case, power take-offs of different lengths can be used.
    The strut 34 is pivotally connected to the rear of the housing 1 above the power take-off shaft 4. The inverted U-shaped connecting frame, shown by dotted lines in FIG. 1, of known construction can be connected to the rear end of the lower arms 14 and 15 and the rear end of the tie rod 34. The mounting link 35 is connected to the inside of the housing 1 and the lower one. the front part of the rocker arm 5. The link 35 has a retractable hydraulic actuator or hydraulic cylinder 36, the front end of which is pivotally connected to the housing 1. The rear end of the rod 37 of the actuator 36
    is attached to one end of a force or load sensor 38 of a known type. (Although the sensor 38 load (figure 2) of the capacitive type, within the limits of the proposed device, you can use sensors of the resistive or inductive type). The other end of the load sensor 38 is pivotally connected to the beam 5 so that the hitch axis 24 passes through the rear end of the pivotally connected load sensor 38. If there is no need to determine the load, then the load sensor 38 may be absent, and in this case the rear end of the rod drive
    pivotally connected to the beam 5.
    There are no parts mechanically connected to the housing in the load cell, which provides a simple and compact version of the link device 35 and the load sensor 38.
    By placing the installation link 35 and the corresponding load sensor on the underside of the rear axle housing, the installation link 35 does not affect the other elements installed in the rear of the tractor. Such a device also provides a good rear view to the tractor driver when maneuvering with a hitch in order to set it in an appropriate position for connection with the land-processing equipment. If a load cell is not required, then link 35 may be replaced by a rigid link (not shown

    To adjust the position of either the lower arms 14 and 15 or t g 11, fluid is supplied to the hydraulic cylinder 36 to extend or retract the mounting link 35. This will cause the rocker arm 5 to rotate about axis 3. Since the shaft axis 3 is above the lower arms and Such a turn leads to a horizontal forward and backward movement of the lower levers 14 and 15 and the inclination of the rod 11.
    The vertical installation of the lower arms 14 and 15 is achieved by supplying fluid to the lifting cylinders 27 and 28, whereby the lower arms are rotated relative to the rocker arms 5 along the axis 24 of the coupling. If the lifting cylinders 27 and 28 are double acting, as shown in the drawings, then the downward hydraulic force can have an effect on the lower arms 14 and 15. Such a force can be useful when an implement, such as a plow (not shown), is connected to the lower arms. .
    The towed equipment 11 (not shown) may be connected to its rear end in a known manner. The tool on the hitch may be attached to the frame of the connecting device or, in the absence of this frame, directly to the rear ends of the lower and upper lifting arms.
    If the equipment is attached, the pulling forces caused by the engagement of the gun with the ground are transmitted to the yoke 5 through the lower arms 14 and 15 and from the yoke 11. From the yoke 5, the pulling force component is transmitted to the setting link 35, where it can be detected by the sensor 38 load. Depending on the type of sensor, the control system may be used, to control the vertical position of the lower arms 14 and 15 in the case of using coupling equipment or to control remote cylinders (not shown), as a function of the shown force sensor.
    Since the link 35, the lower arms 14 and 15 and the tons 11 are oriented in the same plane, the horizontal component force is transmitted non-. mediocre on the link 35.
    Thus, the articulation of the rocker arm 11 through the axis 3 does not support the component of the pulling force.
    51286101
    which is transmitted to link 35, thereby reducing the amount of frictional loss generated in the hinge support. Such a reduction in frictional losses reduces the hysteresis error in the overall operation of the fastening mechanism with respect to the determined pulling force.
