Description

The utility model relates to agricultural engineering and can be used for sowing crops.

Known narrow-row coulter having two discs set at an angle of 18° to each other. During operation, the coulter forms two grooves with a row spacing of 7.5 cm, where seeds and fertilizers fall. Seeds moving along the seed tube are divided into two streams with the help of a separating funnel fixed between the disks under the neck of the coulter body (Karpenko A.N., Khalansky V.M. Agricultural machines - 5th ed. Revised and additional - M. : Kolos, 1983. - S. 141). The disadvantage of the narrow-row coulter is the uneven sowing of seeds and their thickening along the row.

A well-known design is a narrow-row double-disk opener (RU 2427124 C1, 27.08.2011) having a body and two disks mounted at an angle of 18° to each other. A plate is installed between the disks to form a horizontal profile of the seed bed and a seed scatterer behind it. The disadvantage of this coulter is the shaper of the seed bed, which has the shape of a flat plate. When the opener is working, the profiler leaves behind a flat strip, which leads to the rolling of seeds over the seed bed and has a bad effect on the uniformity of their distribution.

The closest in technical essence to the proposed invention is the unit described in the patent (RU 2427124 C1, 27.08.2011), which coincides with it in most essential features and, in accordance with this, was chosen as a prototype.

The purpose of the utility model is the uniform distribution of seeds over the seed bed, by preventing them from rolling. This is achieved by the fact that the profiler is made toothed, after which grooves remain on the bed.

A coulter containing a body, two discs installed at an angle of 18° to each other, a seed scatterer and a profile former are installed between the disks to form a horizontal profile of the seed bed, characterized in that the profile former is made toothed to form grooves on the bed that prevent seeds from rolling, and provide uniform distribution of seeds throughout the seed bed.

This technical result will ensure the most complete fulfillment of agrotechnical requirements during sowing, ensuring a uniform distribution of seeds over the seed bed.

The figure 1 shows the proposed opener, side view. The coulter consists of a body 1, two disks 2 located at an angle of 18° to each other, a toothed seed bed profiler 3, a seed spreader 4. Figure 2 shows a toothed profiler front and side view.

The coulter works as follows. When the coulter is working, the discs 2 (Figure 1) form two grooves with a row spacing of 7.5 cm. The tooth profiler 3, located between the discs, forms the profile of the seed bed, shifting the soil from the row spacing to the discs at the seeding depth, and leaves behind small grooves. From the seed tube, the seed flow enters the diffuser 4. After that, the seed flow is distributed over the entire width of the seed bed, falling into shallow grooves. The sown strip between the discs is 6.5-7.0 cm.
