Description

The device for the spread sowing of small seeds

The invention relates to agricultural machinery, in particular to seeders for sowing grass seeds.

Known grain seeder NWT-3.6, designed for sowing seeds of grain crops and small loose seeds of legumes and loose seeds of cereal grasses, containing disk coulters, keeled coulters, grain grass sowing apparatus, apparatus for sowing small grass seeds.

The disadvantage of this grain seeder is that the seeds are sown in the grooves, and not in a scattering manner 1.

Also known is a working body for subsoil scattering of seeds and fertilizers, containing a stand with a paw and two shields fixed on it, a seed tube with a reflector mounted under it and a wedge-shaped diffuser, whose curved wings are filled with parabolic shape and truncated by vertical planes located at an angle to the plane of symmetry working body and forming a dihedral angle, the apex of which is directed towards the rear end of the diffuser. The wedge-shaped wings of the diffuser are truncated by a plane perpendicular to the plane of symmetry of the working body and passing through the point of intersection of the diffuser edge with its rear end at an acute angle to the diffuser edge.

The disadvantage of this working body is that it sows seeds to a depth of 4 ... 6 cm. At a shallower depth, the soil is covered with a cultivating paw, which does not allow sowing small-seeded crops that require a small seeding depth of I ... 3 cm.

The objective of the proposed technical solution is to ensure the dispersal of seeds along the bottom of the furrow over the entire width of the grip of the cultivator paws and seeding of seeds into the soil to a depth of I ... 3 cm

The task is achieved by the fact that in the device for the spread sowing of small-seeded crops containing a stand with a cultivating paw fixed on it and two shields, the diffuser whose wings are made of parabolic shape, the upper part of the diffuser is oval in shape, longitudinal holes are cut out on the side surface of the parabolic wings of the diffuser 10 to 60 mm and a width of 2 to 5 mm, and the cultivating leg is equipped with spring fingers - harrows articulated in the area of the rack connection paw, with fulfillment of vibrational movements in the horizontal plane. Before the cultivating paw is installed

unloader, the lower edge of which is located in the same plane with the blade of the cultivator paws. Behind the fingers - harrows there is a zagotach fixed by means of traction to the frame. The device rack is made hollow.

The technical solution is illustrated by drawings, where in Fig.1 shows a diagram of a device for the dispersed sowing of small seeds, in Fig. 2 cultivator paw with spring fingers - harrows, in FIG. 3 diffuser, in FIG. 4 - unloader.

The device for the spread sowing of small-seeded crops contains a rack 1, to the lower end of which a cultivating paw 2 with two shields 3 is attached, a diffuser 4 with holes on the sides is installed in the sublap space. In front of the cultivator paw there is an unloader 5, the lower edge of which is located in the same plane with the blade of the cultivator paw. The cultivator paw is equipped with 6-harrow fingers pivotally mounted in the zone of connection of the rack with the paw, behind which there is a claw 7 fixed to the frame 8 by means of a traction 9. A device for the spread sowing of small seeded crops works as follows. When moving across the field, the unloader 5 removes the upper dry soil layer, shifting to the sides. The cultivating paw 2, which follows, slides along the bottom of the open furrow, forming the necessary space for the targeted distribution of seeds along the bottom of the furrow. The seeds of the sown culture through the hollow rack 1 fall on the diffuser 4 mounted in the center of the rack and through the holes in the side surfaces of the parabolic wings fall on the middle part of the furrow. Most of the seeds reflected from the diffuser sow the lateral parts of the bottom of the furrow. Following spring fingers - harrows 6 partially cover the seeds in the furrow with a moist soil layer not deeper than 1 cm. The soil removed by the retortach 5 is dumped by the zagrotachka 7 into the furrow to the required size, thereby ensuring the same seed placement depth.

Holes on the lateral surface of parabolic wings should not be cut less than 10 mm long, as the required surface seeding under the diffuser, more than 60 mm, will not be ensured; there is an increase in the seeding rate in the center of the bottom of the furrow, and a width of less than 2 mm since the rate of sowing of seeds decreases in the center of the bottom of the furrow, more than 5 mm since there will be a significant increase in the seeding rate in the center of the bottom of the furrow.

A prototype of the device for the spread sowing of small-seeded crops was made and tested in the field. Tests have shown that the application of the proposed technical solution allows the sowing of seeds of small-seeded crops on dry soil in a moist soil layer with their high-quality and uniform seeding to the required depth of 1 ... 3 cm and the entire width of the grip of the cultivator paw, which helps increase productivity by 25 ... 30% due to the uniform germination of seeds and the emergence of friendly seedlings.
