Description

This device relates to the field of agricultural engineering, namely to seeders for sowing grain crops.

A drill coulter is known from the prior art, equipped with two parallel-mounted discs that raise the soil layer stuck between them and adjacent to the discs with a two-sided wedge, which serves to feed seeds under the soil layer passing over the wedge, characterized in that, for the purpose of simultaneous application under the soil layer of the seeds of two different cultures, the seed tubes are located on the sides of the discs along the width of their arrangement and the lower ends are inserted into the wedge cavity [SU No. 71141 A1, A01C 7/20, 01/01/1948].

The problem to which the claimed technical solution is directed is to expand the technical capabilities of the device by providing sowing of grain crops with 10 cm spacing, increasing the yield of the cultivated crop and reducing energy consumption.

This task is achieved due to the fact that the opener of the grain seeder includes a traction frame, two flat disk knives with bearing hubs mounted parallel to the draft line at a distance of 100 mm from each other, bump tube coulters, dividing funnel, and a flange is rigidly fixed to each disk knife 30 mm wide and 100 mm in diameter smaller than the diameter of the circular knife, in addition, the traction frame at the back has a guide for the oral tube coulters with the ability to control the depth of seed placement, adjust directly schischalku for flanges and brackets for connecting the chain earthing devices.

The technical result provided by the given set of features is to improve the uniformity of seed distribution over the field area due to sowing seeds with 10 cm row spacing, more accurate seed placement in depth due to the use of flows, increasing the yield of the cultivated crop while reducing the seed rate by 25%, the account of using 18 instead of 24 sowing devices in the C3 seeder in the workflow is 3.6 A.

The device is illustrated in FIG. 1, which shows the opener of a grain seeder - side view, in FIG. 2 opener - a top view where the dividing funnel is not shown, and in FIG. 3 is a view of the opener in the direction of arrow A, which shows the oral tubular openers with a dividing funnel.

The seed drill coulter includes a traction frame 1, two flat disk knives 2 with bearing hubs 3 mounted parallel to the traction line at a distance of 100 mm from each other, oral tube coulters 4, dividing funnel 5, and a flange 6 is fixed to each flat disk knife 2 a width of 30 mm and a diameter of 100 mm less than the diameter of a flat disk knife 2, in addition, the traction frame 1 at the rear has a guide 7 for the oral tube coulters 4, with the possibility of adjusting the depth of seed placement, an adjustable wiper 8 flanges 6 and 9 holders for connecting the chain earthing devices.

The device operates as follows.

At the C3 production seeder - 3.6 A in the front row, 12 double-disc row coulters are removed from the leashes, 6 odd coulters are removed from the leashes in the second row, coulters are removed from the odd coulters, leaving the coulters of the rear row of coulters and then mounted in the front row 12 new made seed drill coulters, and 6 new coulters are mounted in the second row. Thus, 18 new coulters will be located on the seeder, forming 36 rows with 10 cm row spacing, therefore 1, 5, 9, 13, 17, and 21 sowing units that are blocked in the grain box by shutters will be excluded.

During the movement of the seeder with the new openers lowered into the working position, the coils of grain and fertilizer apparatus, rotating, capture the seeds and fertilizers and throw them into the funnel of the seed tubes. Through the seed tubes connected to the separatory funnels 5, the seeds and fertilizers are divided into two streams and enter the oral tubular openers 4, mounted on the guides 7 of the traction frame 1, and then, rolling along the tubes of the oral tubular openers 4, fall to the bottom of the groove formed by the toe (on-board) of the coulter in the soil. The ribs 6, rigidly mounted on flat disk knives 2 with bearing hubs 3, support a given depth of seed and fertilizer placement, and flat disk knives 2 themselves, cutting the soil to a depth of 5 cm each, cut weed vegetation and thereby make it easier for the narral tube opener 4 to form necessary groove depth. Adjustable wiper 8, mounted on the guide 7 of the traction frame 1, eliminates the buildup of soil on the working surface of the flange 6, thereby ensuring a constant depth of seeding of seeds and fertilizers. Sealing of grooves with seeds and fertilizers is carried out by chain shutters (not shown in the diagrams) attached to the holders 9 of the guide 7 of the traction frame 1.

Thus, when using the proposed openers on a grain seeder, it is possible to improve the uniformity of seed distribution over the field area due to sowing seeds with 10 cm row spacing, more accurate seed placement in depth due to the use of flows, increasing the yield of the cultivated crop with a 25% decrease in the seed sowing rate , due to the use of 18 instead of 24 sowing devices in the C3 type seeder - 3.6 A.
