Abstract

Usage: agricultural engineering, in particular, wide-spread tillage implements with rotary working bodies. SUMMARY OF THE INVENTION: A wide-grip disc cultivator comprises a frame articulated from sections on vane support wheels, an attachment hitch, and two rows of disc working bodies assembled into batteries. The vane axles of the front wheels are mounted in bushings swaying in the vertical plane. The bushings are pivotally mounted on the frame and connected by means of rods and brackets to the rotary axis of the lifting and lowering mechanism of the working bodies. In the upper part of the vane axles of the front wheels two-arm levers are rigidly mounted, resting in the working position on the adjustable screw stops mounted on the frame. 4 ill.

The invention relates to agricultural machinery, in particular to wide-tillage cultivating implements with rotary working bodies.

A wide-grip tillage implement is known, including a sectional frame, two-row sections of working bodies, front and rear vane wheels with parallelogram hydroficated mechanisms for moving the working bodies into working and transport position, working and transport hitch.

The disadvantages of this tool are the structural complexity of the control and adjustment mechanisms of the support wheels, which reduces its operational reliability and productivity.

The purpose of the invention is to increase the efficiency of the use of the gun by increasing the reliability and reducing the labor costs of tuning into operation.

This goal is achieved by the fact that the vane axles of the front wheels are mounted in bushings swaying in the vertical plane, articulated by means of t and one-arm levers with a rotary axle for lifting sections of the working bodies, and the vane axles themselves are equipped with two-shouldered levers, the opposite ends of which are supported in the working position on the adjustable stops fixed on the frame, whereby the locking of the inclined thrust position of the front wheels of the implement is achieved.

Comparative analysis with the prototype shows that the claimed tool has a smaller number of kinematic links of the support wheels control mechanisms, including rigidly fixed

brackets mounted on the rotary axis of the working bodies, connected through rods to bushings of the front axle fpuger axles mounted on horizontal hinges, the tilted position of which in operation is ensured by rotation of these axes, equipped with two-arm levers rigidly fixed on them when the latter meet the stops of the supporting frame.

The invention is illustrated in the drawings. Figure 1 presents a diagram of the gun in plan; figure 2 is the same side view in the working position; Fig. 3 is a side view in a transport position; figure 4 is a top view of the front wheel mechanism.

The wide-disc disc cultivator includes a frame 1 pivotally articulated from sections on front vane 2 and rear 3 wheels, a mounted hitch L with a rotary working spoke 5 and a hydraulic cylinder 6 for lifting the hitch to the transport position, side transport bale 7, articulated axle 8 with spring-loaded sections 9 of rotational working bodies 10 installed in two rows. Brackets 12 are rigidly fixed to the rotary axes 8 through idro cylinders 11, which are pivotally connected via links 13 to bushings 14 of the axle axles 15 of the front wheels 2, EI carts 14 are suspended to the transverse beams of the frame 1 through horizontal schlirnets 16. At the upper ends of the vane axes 15, two-arm levers 17 are rigidly fixed, the opposite ends of which in the working position of the guns are supported by length-adjustable stops 10 connected with the frame 1. The hydrocyclopedia rods 11 are provided with cap clamps 19. In the transport position, the cultivator aggregates with a tractor by sniiy 7. Attachments Coupling 4 is raised and the hydraulic cylinder 6 is fixed to the frame 1. The rods of hydraulic cylinders 11 put forward and secure with crown straps 19. The axis is turned by hydraulic cylinders 11 in the horizontal cage frame 1, are raised working bodies 10 above the soil level. When the brackets 12 are echoed, the sleeves And with the vane axles 15 are pushed to the vertical position in which they are held due to the location of the axis 8 center and the hinges of the brackets 12 and 3 on the same line, which excludes the transmission of the turning moment from the supporting reaction the front wheels on the axis 8. In this position, the two-arm levers 17 do not support the HP thrust 10, which ensures that the axle 15 is free yarn in the bushings 14, and the cultivator can maneuver

In operating position afegatmroilnie with a tractor is carried out 5

by turning and fixing it on the hitch 4, the necessary angle of attack a of the working bodies 10 is selected. When moving, the cultivator frame 1 independently goes to

this angle is located diagonally to the direction of movement. The latches 19 are folded back, the rods of the hydraulic cylinders are retracted, the working bodies 10 interact with the soil. Due to the rotation of the axis 8 with the brackets 12 through the rods 13 there is a tilt in the vertical plane of the bushings 14 with the vane axles 15 of the front wheels 2 by an angle of p 40 ... 45 °. With this movement, one of the ends of the two shoulders of the lever 17 reaches

its stop 18 and rotates the axis 15 with the wheel 2 at an angle y coinciding with the yi scrap of attack of the working bodies 10. In the final phase of the inclination of the sleeve 14 around the hinge 16, the second end of the lever 17 also reaches

its emphasis 18 and the lever 17 fixes the axis 15, excluding its rotation in the sleeve 14.

Thus there is a tilt, rotation and fixing of the vane axles 15 whereby the front wheels 2

automatically set to an inclined thrust position in which their plane of rotation coincides with the direction of movement. The latter is achieved by adjusting the length of the screw stops 18.

When the unit is moving, the horizontal components of the support reaction arising from the inclined position of the front wheels 2 compensate for the lateral pressure of the soil on the working bodies 10, excluding it

transmission to the tractor trailer. The rear wheels 3, depending on the hardness and depth of cultivation, can be raised above the level of soil1, or they can easily touch it without leaving distinct traces.

Using the proposed device will improve reliability, performance and reduce the complexity of the preparation for operation of a wide-disk disc cultivator.
