RU216996U1 - Coulter with roller profiler - Google Patents

Abstract

The coulter refers to agricultural engineering and can be used for sowing grain crops. The purpose of the utility model is to form the profile of the seed bed and roll the soil before the seeds fall on it for more efficient use of soil moisture and more friendly emergence of seedlings of grain crops. This is achieved by the fact that in the interdisk space of the coulter a roller profile former is installed, equipped with a roller rotating and moving along the track of the row, fixed through a figured plate to the coulter body by a bolted connection.

Description

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

Known narrow-row coulter having two discs mounted 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 discs 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 along the row.

A known design is a narrow-row double-disk coulter (RU 2427124 C1, publ. 08/27/2011), 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 (profile former) and a seed scatterer behind it. The disadvantage of this design is a profiler made of a plate, which does not provide soil rolling before seeds fall on it, and this leads to a lengthy seed germination period due to poor contact with the soil and insufficient moisture, especially on light soils.

The closest in technical essence to the proposed utility model is the unit described in the patent (RU 2427124 C1, publ. 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 to form the profile of the seed bed and roll the soil before the seeds fall on it, for more efficient use of soil moisture and more friendly emergence of seedlings of grain crops. This is achieved by the fact that in the interdisk space of the coulter a roller profile former is installed, equipped with a roller rotating and moving along the track of the row, fixed through a figured plate to the coulter body by a bolted connection.

A coulter containing a body and two disks installed at an angle of 18° to each other, between the disks a profiler is installed to form a horizontal profile of the seed bed and a seed spreader behind it, characterized in that to form the profile of the seed bed and compact the soil before the seeds fall on it , the profiler is made in the form of a rotating roller fixed to the body through a figured plate.

This technical result will ensure the most complete fulfillment of the agrotechnical requirements of sowing, when it is necessary to compact the seed bed before seeds fall on it, which provides the most favorable conditions for intensive germination of seeds of grain crops, which leads to an increase in yield.

In FIG. 1 shows the proposed coulter, side view. The coulter consists of a body 1, two disks 2 located at an angle of 18° to each other, a roller seed bed shaping machine 3, and a seed spreader 4. In Fig. 2 shows a roller profile former, front and side view.

The coulter works as follows. When the coulter is operating, the discs 2 (Fig. 1) form two grooves with a row spacing of 7.5 cm. The roller profiler 3, located between the discs, forms the profile of the seed bed and rolls the sown row, shifting the soil from the row spacing to the discs at the seeding depth. 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. The sown strip between the discs is 6.5-7.0 cm.

Claims (1)

A coulter containing a body and two disks installed at an angle of 18° to each other, between which a profiler is installed to form a horizontal profile of the seed bed and a seed spreader behind it, characterized in that to form the profile of the seed bed and compact the soil before the seeds fall on it , the profiler is made in the form of a rotating roller fixed to the body through a figured plate.
