Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to wide-cut grain pneumatic seals. The purpose of the invention is to improve the quality of sowing by ensuring the stability of the course of the working bodies in the soil and reducing the metal intensity of the attachment mechanism. The parallelogram mechanism is fixed in the rear part of the central frame and is provided with frames 6 for hinging frames of 7 sections 8 of working members 9. The lower link of the parallelogram mechanism is provided with an eye with a hole and a fixing pin. To ensure the rigidity of the frame 6 and the size of the space between the distal hinges of the horizontal and vertical pairs of hinges, a removable link is introduced that passes inside the frame 7. 1 Cp. f-ly, 4 ill.

FIELD OF THE INVENTION The invention relates to agricultural machinery industry, in particular, to the mechanisms of attachment of working bodies to a crop.

The aim of the invention is to increase the stability of the stroke of the working bodies.

FIG. 1 depicts the proposed mechanism of attachment of the working bodies on the grating; in fig. 2 - the same, in the position of long-distance transport; in fig. 3 - view A

The tractor is hinged onto the soil by means of wheels 4 and is fed forward, section 8 being separated from the frame and taking a position perpendicular to the longitudinal axis of the crop. Thereafter, the parallelogram mechanism 5 is lowered into the lower position, the lower link 10 of which is laid down and fixed by the pin 13 in the hole 12.

During sowing the working bodies 9 under

in fig. 4 — node I in FIG. 3 (fixed on the central frame of the parallelogram mechanism in the lower part of Fig. 1 (parallelogram mechanism 10 by the effect of the deeper moment of action and frame of the linkage of the sections of the working parts); they are inserted by means of push rods and shafts

lifting (not shown) to the frame 7, which tends to rise and rotate relative to the inner horizontal ty and the removable link of the section hinge frame). . frame hinge 6.

The attachment mechanism of the working bodies on the cross-section. These forces are transmitted by a removable link.

14 by means of hinges on the lower link 10 of the parallelogram mechanism 5, which is fixed in the hole 12 of the lugs 11 by means of the pin 13, and since

The center includes a central frame 1 with a centralized capacity 2 for seeds and fertilizers, running wheels 3 and supporting full-turning wheels 4. Parallelogram mechanism 5 is fixed in the rear part of the central frame 1 and provided with frames 6 of the frame 7 of sections 8 of the working parts 9. Lower link 10 the parallelogram mechanism 5 is provided with an eye 1 1 with a hole 12 and a fixing pin 13.

Frames b of the hinge section 8 are used to provide a copy of the soil frame 7 with the working bodies 9 and folding in the transport position. Therefore, frame 6 includes two horizontal hinges for mounting on frame 7 and two vertical hinges for mounting on parallelogram mechanism 5.

To ensure the rigidity of the frame and the constancy of the dimensions between the distant hinges of the horizontal and vertical pairs

the tire is an element of the central frame 1, then the deepening moment is transmitted to the central frame and is compensated by its weight and the weight of the container 2 with seeds and fertilizers.

Thus, the proposed design makes it possible to ensure the stability of the working bodies in the soil and thereby improve the quality of sowing.

Claims (2)

Invention Formula . The attachment mechanism of the working bodies on the forks, including the central frame of the splitter, the parallelogram mechanism fixed in the rear part of the central hinges, the removable link 14 is inserted, the passageway 35 and fitted with the frames of the attachment of the frames inside the frame different in that. The hitch mechanism of the crop works in the following way. In the transport position, the sections 8 with the working bodies 9 and the swivel wheels 4 are fixed and raised in the front part of the crop together with the central hitch of the tractor. When transferring from the transport position to the working front part of the spus 40 that, in order to increase the stability of the stroke of the working bodies, the lower link of the parallelogram mechanism is made with the possibility of fixation on the central frame. 2. The mechanism according to claim 1, characterized in that the frame is provided with a removable stiffening element, made with the possibility of free passage inside the sections of the working bodies. The tractor is hinged onto the soil by means of wheels 4 and is fed forward, section 8 being separated from the frame and taking a position perpendicular to the longitudinal axis of the crop. Thereafter, the parallelogram mechanism 5 is lowered into the lower position, the lower link 10 of which is laid down and fixed by the pin 13 in the hole 12. During sowing the working bodies 9 under  the effect of the deepening moment is exerted by means of push rods and shafts 14 by means of hinges on the lower link 10 of the parallelogram mechanism 5, which is fixed in the hole 12 of the lugs 11 by means of the pin 13, and since the tire is an element of the central frame 1, then the deepening moment is transmitted to the central frame and is compensated by its weight and the weight of the container 2 with seeds and fertilizers. Thus, the proposed design makes it possible to ensure the stability of the working bodies in the soil and thereby improve the quality of sowing. Invention Formula 0 that, in order to increase the stability of the stroke of the working bodies, the lower link of the parallelogram mechanism is made with the possibility of fixation on the central frame. 2. The mechanism according to claim 1, characterized in that the frame is provided with a removable stiffening element, made with the possibility of free passage inside the sections of the working bodies.
