Abstract

The invention relates to agricultural machinery, in particular, to the construction of a stack of lifting devices for mounted tillage implements in hydraulic tractor systems. The purpose of the invention is to reduce the time spent on adjusting the length of the stitch by reducing the number of operations. The stitch consists of two coaxially mounted outer 1 and inner 5 mutually movable telescopic elements. Both telescopic elements are provided with apertures 2.6 for mutual fixation by means of a finger 9 with a bracket. The outer telescopic element is further provided with a groove 3 for providing a movable connection of the telescopic element and a fork 4 for connection to the lower arms of the hinged device. The inner telescopic element 5 has a threaded part 7 for movable connection with the screw 11. The screw is made of two parts, one of which is equipped with a hinge for connecting it to the back of the tractor. The hinge includes a fork and an earring 14, through the opening 16 of which a screw 11 passes. On the other part of the screw, a thread 7 is made to connect the screw to the inner telescopic element 5, while the screw is provided with a spring 22 placed between the link 14 and the stop fixed to the body of the screw. The screw 11 is provided with a U-shaped handle 20, which is fixed on the lips 8 of the internal telescopic element 5. 1 Cp. F-crystals, 2 Il.

FIG. one

The invention relates to agricultural machinery, in particular, to the construction of a stack of lifting devices for mounted tillage implements in hydraulic tractor systems.

The purpose of the invention is to reduce the time spent on adjusting the length of the stitch by reducing the number of operations.

FIG. 1 shows the stacking, general view; in fig. 2 - the same, side view;

The clamp contains an outer telescopic element 1 with holes 2 ,. a longitudinal groove 3 and a fork 4 for connecting to a longitudinal tam hinged device and an internal telescopic element 5 with openings 6, an internal thread 7 and two pairs of balds 8. The telescopic elements are mounted in parallel and interconnected by a finger 9 with a bracket 10 covering the surface of the outer telescopic element I,

The inner telescopic element 5 is connected to a screw 11 consisting of a hinge formed by a fork 12 with openings 13 for connecting to the tractor frame and a link 14, interconnected by a finger 15, and the body of a screw 11 mounted coaxially with the hinge and passing through the hole 16 in the earring 14. At one end of the screw body, the head 17 is made, at the other end there is a threaded part 18, and in the middle part there is a hole 19 in which a handle 20 with working surfaces 21 is installed, and a spring 22 is installed which is supported by one end in earring 14, and others with the brace, into the bearing surface of the washer 23 supported by the handle 20.

The straightening length is adjusted as follows.

The bracket 10 is retracted from the outer telescopic element and the finger 9 is pulled out of the holes in the telescopic elements 1 and 5. The telescopic elements move relative to one another, providing the required length of the tie, and fixed by the finger 9 and the bracket 10.

In order to more precisely adjust the length of the straps, the working surfaces 21 of the handle 20 are removed from the mating with the tracks 8 of the inner telescopic element 5. The body of the screw 11 is screwed into the inner telescopic element 5 or turned out of it by rotating the handle 20 to one side or the other. After adjusting the grip length, the handle 20 is lowered onto one of the pairs of coats 8 of the inner telescopic element and closes it with working surfaces 21, preventing rotation of the body of the screw 11 in the threaded part of the inner telescopic element 5. To provide a movable interconnection of the telescopic elements It is necessary to place the finger 9 into the groove 3 of the outer telescopic element 1 and into one of the holes b of the inner telescopic element 5 and fix the finger 9 with the bracket 10.

When a compressive force occurs when the attachment unit rotates with the mounted tool, which can lead to breakage of the cushion components or mounting components of the casing to the tractor frame and lower tires, the body of the screw 11 moves relative to the shackle 14, compressing the spring 22 until until the opposite strand comes into play, the perceiving tensile forces that limit the movement of the attachment.
