Description

FIELD OF THE INVENTION The invention relates to agricultural machinery, namely, seeding devices of seeding machines.

A sowing apparatus is known, which includes a bunker, a seed cutter, a folding bottom, a sowing disc, springs and their fastenings 1.

However, this apparatus does not exclude damage to the grains, does not ensure their single-grain seeding, and requires the installation of a separate sowing apparatus on each of the openings.

A sowing device is also known, which contains a bunker, a sowing disc with seed cells, a mechanism for filling cells with seeds, and a plate 2.

The disadvantage of this apparatus is that it does not preclude damage to the seeds, which leads to a deterioration in the quality of sowing.

The purpose of the invention is to improve the quality of sowing by reducing the degree of fragmentation of seeds.

The goal is achieved by the fact that the mechanism for filling the cells with seeds is made in the form of brushes, which are mounted on a rod connected to the reciprocating drive, and is located above the sowing disc, the latter having radial slots in which interchangeable plates are installed. The cells are made in replaceable plates.

In addition, the sowing disc is equipped with podpoddzhinennymi flaps, which are movably mounted under the plates, and on the drive shaft of the reciprocating movement is fixed a cam, which interacts with the flaps.

FIG. 1 shows the sowing unit, section; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 — node I in FIG. one; in fig. 5 shows a section B-B in FIG. one.

The sowing machine consists of a hopper 1 for grain, a sowing disc 2 with plates 3 installed in its radial slits with conical surfaces around the perimeter and seed cells. Valves 4 are installed under the plates, which are movably connected with guides 5, which are bolted to the sowing disc. The flaps are made with holes similar to interchangeable cell plates. At the ends of the flaps, there are protrusions 6, the inner ones of which are connected to the springs 7 fixed to the vertical shaft 8 of the actuator 9, and the outer ones are arranged to interact with the cam

10, made in the form of a rotating plate fixed on the shaft 11. The gears 12 of the reciprocating drive are made with gear ratios ensuring the synchronous operation of the elements of all the mechanisms, and the drive 9 itself is of adjustable speed.

A brush 13 is mounted above the sowing disc, fixed by springs 14 on strap 15, which is connected at one end with eccentric 16, and the other through a longitudinal groove is placed on axis 17. Eccentric 16 is fixed on shaft 11. Nozzles 18 are fixed on gates 4, and under them pneumatic sem receiver 19 of ejector type with sem-insulated wires.

In the upper part of the receiver from the front side, an excess air flow is connected to each seed wire. The sem receivers are connected to the coulters via elastic sem wires 20.

Sowing machine operates as follows.

From the hopper 1, the seeds go to the rotating disk 2 and are collected in the area of the brushes 13, which at the same time make oscillatory movements due to the springs 14 and the rotation of the eccentric 16 that transmits the movement to the bar 15. With the plates 3 passing under the brushes, the seeds are placed one by one in the cells. Each plate 3 passes through several brushes (e.g., three), thereby eliminating the possibility of missing seeds in the cells. Dust seeds from the area of the plates 3 (not trapped in the cells) are brushed off. During rotation of the disk 2, the protrusions 6 of the shutters 4 are periodically on the cam 10. In this case, the shutters are displaced along the guides 5 to the center of rotation, compressing the spring 7, and the holes in the surfaces of the shutters 18 are aligned coaxially with the cells of the plates 3. Under the action of the weights and the ejected air flow, the seeds from the cells enter the receivers 19 and, through this wire 20, into the openers of the seeds. Moreover, when opening one damper, the seeds are ejected simultaneously at the full width of the seed. The frequency of seeding in rows is regulated by the speed of rotation of the working disk connected through gears 12 to the drive 9, which has an adjustable number of revolutions.

The proposed device significantly reduces seed damage, thereby increasing the quality of the crop and yield.
