Description

(54). DEVICE FOR THE PREVENTION OF THE USE OF AGRICULTURAL EQUIPMENT WHEN WORKING ON THE SLOPES

one

FIELD OF THE INVENTION The invention relates to agricultural machinery, namely, devices for preventing the sliding of implements when working on slopes.

A device is known for preventing agricultural implements from slipping when working on slopes, containing a rotating circular knife mounted on a frame, mounted at a predetermined angle to the tractor's trajectory, a circular knife rotating mechanism relative to the vertical axis, which is designed as a hydraulic cylinder, controlled by a spool valve, hinged on the tractor and kinematically connected with the element connecting the tractor with the tool 1.

This device allows you to control the deflection of the cannon relative to the tractor, but it does not take into account the deviation of the longitudinal axis of the tractor relative to the direction of motion.

The closest to the proposed technical essence and the achieved positive effect is a device to prevent the agricultural implements from slipping during operation.

on the slopes, including a frame and a disk knife, the axis of which is connected to the hydraulic cylinder operated by the distributor, by means of which the rotary lever with the self-adjusting disk 2 is connected with the frame.

The disadvantage of this device is that in the initial period of operation of the turn, the disk knife promotes the sliding of the cannon.

The purpose of the invention is to increase the stability of the course of the guns at the beginning of the gons.

Claims (2)

This goal is achieved by the fact that the device is equipped with a plate mounted on a pivoting lever, an emphasis placed on the frame of the gun, made with grooves under the plate, and limit switches of f5 of the gate lever, while the circular blade has adjustable pivot stops. Such a device makes it possible to fix the pivot arm in the extreme position that it occupies after cutting down the cannon before the start of the turn of the aggregate, therefore, when the cannon goes deep after the 20th gate, the disc knife is turned in an upward direction on the slope and prevents the cannon from sliding. FIG. 1 shows a device for preventing agricultural implements from slipping when working on slopes; in fig. 2 - the same, in the position with the recessed tool before the start of the turn to perform the adjacent working pass in the opposite direction; in fig. 3 shows the position of the device for preventing the agricultural implements from slipping on the slopes at the initial moment of operation after a turn. The device for preventing sliding of agricultural implements when operating on slopes includes a frame (not indicated in the drawing) and a disk knife 1, the axis of which is connected by means of link 2 to a hydraulic cylinder 3 controlled by a distributor 4, by means of which a rotary lever 5 sec is connected to the frame self-aligning disk 6. Plate 7 is mounted on the pivot arm 5. A support 8 is mounted on the frame, made with the turning pins 5 of the pivot arm 5 and the slots 10 under the plate 7. The plate 7 enters the slots 10 with the rightmost (B) and evom (C) positions of the pivot arm 5, moreover, the circular knife 1 has adjustable stops 11 rotation. The device operates as follows in the first pass of the gun, which is performed at the point of maximum inclination of the field with fully reversed stoppers 11 of the rotation of the disk knife 1, during steady state operation, the unit is stopped and the adjustments of the turn stops 11 are set so that one of them The blade 2 is in contact with the link 2, and the other is placed symmetrically with the first relative to the middle position of the link 2. After the tool has been dug at the end, the floor of the self-aligning disc 6 comes out contact with the soil, the pivot arm 5 is lowered down until the plate 7 is in contact with the stop 8. Under the influence of the slope the pivot arm 5 moves to the left (down the slope) to the stopper 9, the plate enters the groove 10 and the lever takes position C. At the same time, the distributor rod 4 moves to the extreme left position, as a result of which the disk knife 1 will turn to the left until the link 2 with the rotation limiter 11 is touched. After the unit is turned to move in the opposite direction, the rotary lever 5 is held in the leftmost position with the help of plate 7 and groove 10, therefore, when lowering the tool into the working position, the disk knife 1 is turned to the left and prevents the tool from sliding. Limiting the rotation of the disc knife 1 ensures that the cultivator transitions to the established mode without cutting cultivated plants with vibrations of the implements within the protective zones. When the gun is lowered into the working position after the self-aligning disk 6 contacts the soil, the plate 7 leaves the groove 10 and the swivel lever 5 occupies position D. The use of this invention improves the stability of the tool movement at the beginning of the gons and thereby reduces the damage to plants on the headlands. Apparatus of the Invention A device for preventing agricultural tools from slipping when working on slopes, including a frame and a disc knife, the axis of which is associated with a hydraulic cylinder controlled by a distributor, by means of which a pivoting lever with a self-aligning disk is connected to the frame, characterized in that increasing the stability of the course of the guns At the beginning of the gons, it is equipped with a plate installed and a pivot arm placed on the frame of the gun with an emphasis made with grooves under the plate and turning stops on orotnogo lever, wherein the circular knife has an adjustable turning guides, information sources, the received note in the examination 1.Avtors1 (th certificate USSR № 298270, cl.
