Abstract

FIELD: agriculture; machine building.

SUBSTANCE: unit for non-contact seed and fertilizer sowing contains a shaft with spherical discs, tuko and seminal ducts, springs and a vomer section with openers. In this case, openers are installed with the possibility of adjusting the depth of seeding with the help of adjusting brackets. Opener's paws are located above the ducts, in between and behind them. On the tool frame, an air-hydraulic cylinder is installed, connected to the vomer section and performing the function of a damping device.

EFFECT: invention will allow to improve the quality of non-contact seed and fertilizer sowing due to the uniformity of seed filling in depth and the creation of a compacted bed for seeds.

Description

The invention relates to agricultural machinery, in particular to tools for non-contact sowing of seeds and fertilizers.

A device is known "Soshnikovy battery" [RU 2125359 C1, A01C 7/20, 01/27/1999], including a shaft, spherical disks and racks installed between them with fertilizer and vas deferens, moreover, on each rack paired narralniks are fixed, the lower edges of which are placed on the level of the lower edge of the spherical disks, while the working surfaces of the narraliks are made in the form of convex parts of truncated spherical segments facing each other, and a pipe line is located in front of them in the direction of travel.

A disadvantage of the known device is that the cutting of the bottom of the furrow with spherical disks is carried out unevenly with grooves and ridges remaining on the soil surface, and the process of simultaneous sowing of seeds with the introduction of fertilizers and rolling is accompanied by uneven sowing in depth.

This device is closest to the proposed technical solution and is taken as a prototype.

The objective of the invention is to improve the quality of non-contact sowing of seeds and fertilizers due to the uniformity of seed placement in depth and the creation of a compacted bed for seeds.

The problem is solved in that the unit for contactless sowing of seeds and fertilizers, containing a shaft with spherical discs, fertilizer and seed tubes, is equipped with springs and a coulter section with coulters installed with the ability to adjust the depth of sowing using the adjustment brackets, while the coulter paws are located above pipelines, between and behind them. And on the gun’s frame, a pneumatic hydraulic cylinder is installed, connected to the coulter section and acting as a damping device.

The invention is illustrated by the following drawings:

in FIG. 1 shows a unit for contactless sowing of seeds and

fertilizers in isometric form;

in FIG. 2 shows a unit for contactless sowing of seeds and fertilizers, side view;

in FIG. 3 shows a unit for contactless sowing of seeds and fertilizers, top view;

in FIG. 4 shows a unit for contactless sowing of seeds and fertilizers, rear view.

The unit for contactless sowing of seeds and fertilizers consists of a shaft 1, on which spherical discs 2 with pipelines installed between them are located 3. The opener section 4 consists of seed tubes 5 and coulters 6. It is attached to the frame using the adjusting brackets 7, via springs 8, 9. The pneumohydrocylinder 10 is rigidly connected at one end to the frame 9, and at the other end to the coulter section 4.

The opener section 4 is mounted on the frame 9 with the possibility of adjusting the depth of sowing using the adjusting brackets 7.

The unit for contactless sowing of seeds and fertilizers works as follows (Fig. 4).

When the unit moves along the field, spherical disks 2, crashing into the soil, create furrows into which fertilizers are scattered from the pipelines 3.

The coulter paws 6 located above the pipelines, between and behind them, provide sowing of the seeds between the furrows formed by the spherical discs 2. At the same time, the coulters 6 are set to the seed sowing depth according to agricultural requirements using the adjustment brackets 7. Soil unevennesses are copied using springs 8, and the vibrations of the opener section 4, which is suspended on the springs 8, are damped by a damping device, which is a pneumatic cylinder 10. This allows the seed bed to be compacted in accordance with agricultural requirements and.

The proposed design - the unit for contactless sowing of seeds and fertilizers allows you to compact the seed bed by adapting the own vibrations of the opener section to the required values, which gives a more uniform distribution of seeds in depth and, as a result, increase crop yields.
