SU579842A3 - Regulating device for steerable wheels of agricultural machine - Google Patents

Description

one

The invention relates to devices for leveling agricultural machines.

A regulling device for controllable septic tank machines is known, including an electromagnetic hydraulic valve, limit switches and a pilot mounted in a longitudinal vertical plane and equipped with a damper l,

However, the known device does not limit the angle of rotation of the controlled wheels.

The purpose of the invention is to provide stabilization and limit the maximum angle of rotation of the driven wheels of the machine when it oscillates in the longitudinal-vertical plane.

This is achieved by the fact that the device is equipped with a rotation stop, made in the form of a two-armed lever rigidly mounted on the axial finger of the steerable wheel, and a plate hinged on the rear steerable wheels, and the limit switches are mounted on the plate.

It is tine against each two-arm lever, and the plate is kinematically connected through a flexible cable through a flexible cable.

The drawing shows a diagram of the electromechanical principle of compensating slopes on soil using an adjusting device for controlling the rear axis of a grain combine.

The adjusting device includes the rear axle axis 1 of the grain combine. On the back

10 axis wheel 2 with its bearing part 3 is installed pivotally around the pivot pin 4, while turning the wheel by moving the crank 5 of the control cylinder 6, the connecting rod 5 is mounted on the bearing part of the wheel 3, and the control cylinder 6 on the rear axle 1.

Cylinder 6 is controlled by means of a magnetic valve 7 during automatic control and by means of control valve 8 with manual control.

Claims (1)

The system is filled with an injection pump 9 with a drive unit, U, which feeds into the control cylinder, my quantity of oil from the oil tank 11, either directly through the control valve 8, or through the magnetic valve 7, through pipeline 12 or 1-3, resulting in a wheel rotates respectively left or right. At the pivot pin of the trunnion 4 are rigidly mounted for control of the solenoid valve 7 two levers 14, which act when the wheel is turned. When turning too far, these levers turn on the limit switch 15 or 16, depending on whether the angle of rotation is formed, to the right or to the left. Limit switches 15 and 16 are mounted on a rotary plate 17, in which the rotary axis 18 is located a paratissic kingpin of a rotary pin 4. By reproducing the edge by means of a sensor through the control device 19, in accordance with the deviation from this position, the control tiling 6 is filled through the magnetic valve 7 in the right or left side, which provides control of the turn of the wheel. The amplitude of the adjustment is limited by limit switches 15 and 16 through turnips 20 or 21. As with the side slope, the movement along the straight can only occur due to counteraction of the machine skidding, then with a rigidly fixed rotary plate 17 would form an unequal angle of rotation for m 1 step 14, the outcome from the middle position. In order to eliminate this, the grain com- bustor 22, in the capacity of which, for example, a starter battery can be used, is installed on the gate. A damper 23 is connected to the battery in order to soften the slopes with small unevenness of the soil, for example, with funnels. most and limit switches 15 and 16 on the opposite side. By the necessary countering of the skid of the machine, the levers 14 are moved from the middle position, therefore the rotary plate 17 again occupies the middle position with respect to the levers 14, i.e. the adjustment range of the rear wheel 2 remains, however, its position relative to the chassis of the machine varies. Claiming device for controllable wheels / agricultural machine, actuating electromagnetic hydraulic valve, limit switches and master mounted in a longitudinal-vertical plane and equipped with a damper, characterized in that, in order to stabilize and limit the maximum allowable angle of rotation controlled the wheels of the car when it oscillates in a longitudinal-vertical plane, it is equipped with a rotation limiter, made in the form of a two-arm lever rigidly fixed to the axially finger controllable wheel, and a plate, but the hinge attached to the rear axle controlled by the wheels, wherein the limit switches are mounted on the plate against the arm of each double-arm lever and the plate is kinematically via a flexible cable associated with the pendulum.
