Description

(5) SEEDER BOWLER

one

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to the coulters used in sowing implements.

Polosoidal coulters are known for embedding in the socket. containing polozbozdatel, sem wire and zagatach tU.

The disadvantage of so-called coulters is that they do not ensure uniform seeding of seeds in depth with changing microrelief and soil structure, especially with a small sowing depth (2-4 cm), when sowing sugar beet seeds.

Closest to the invention is a srsnik containing a lump (a body, a skid, a sem wire, and a sealing device 12.

The presence of the clod remover ensures that the seeds are sown in the wetter underlying soil layer. The disadvantage of such a coulter

: An unstable depth course remains, with a changing surface microrelief of the floor and the absence of the necessary contact of the seeds with the soil when the soil is heterogeneous in physical condition. This leads to uneven germination of seeds and the subsequent deterioration of the conditions of mechanized plant care.

"about

The aim of the invention is to ensure seeding and embedment of seeds to a predetermined depth, regardless of the change in heat flow from the surface.

15 floor and ensuring the required contact of the seeds with the soil.

Claims (2)

This goal is achieved by the fact that the proposed coulter is equipped with a paw 20 plate, which is fixed along its longitudinal axis of symmetry at the lower edge of the skid perpendicular to its surface. 3 The paw-plate is made with a narrowed back part, above which this wire and sealing device are installed one behind the other. In addition, the narrowed back part of the paw-plate is curved with the end bent down, and on both sides on the plane of the lap-plate facing down, subsoil shoulder blades are installed, oriented to the narrowed back part of the paw plate. In FIG. 1 shows the opener of the crop, general view; in fig. 2 is the same, view along arrow A in FIG. 1; in fig. the same, bottom view. The opener of the village lid includes a housing 1 with this wire 2, a skid 3, on the nose of which there is a clodding organ k, a. on the lower edge, there is a paw-plate 5, which transforms into a narrowed back part 6, bent to the surface of the field to seal the bottom of the groove. On the plane of the paw plate facing the surface of the floor, the subsoil blades 7 are fixed, the rear parts 8 of which are directed inwards towards the shank 6. The sealing element consists of two wheels 9 in the form of truncated cones mounted on a carrier 10 on the axles inclined downwards forward so that the wheels 9 and the shank 6 form a conical stream for compacting and compressing the soil with sprouted seeds. During the opener operation, the lumpy organ k displaces the most dried soil layer with lumps on either side of the opener, and the more pronounced lower soil layer is separated by the vine 3 and slides along the paw not 5 up to the narrowed back part 6. Seeds through this wire 2 fall into the soil layer moving along the paw 5 and, slipping along with the soil, fall into the compression area, forming wheels 9 of the sealing element and the tapered rear part 6, and then compacted and crimped together with the soil are laid in the bozdka. The bottom of the groove is formed by the rear parts of the 8 subsoil blades 7 moving the ground on both sides of the blade under the back of the lower part of the foot-plate, which, with its bent end 14, compresses the bottom of the groove when the coulter moves. The wheels 9 of the sealing element rotate when the coulter moves from the contact of their outer edges with the fixed soil of the floor surface. This opener forms and packs a stream of compacted soil with seeds into the groove, thereby ensuring the same depth of seed embedding, regardless of the surface microrelief of the floor. The preparation by the coulter of the grooves with a compacted bottom for laying the soil stream with seeds ensures the required contact of the seeds with the soil, since the soil does not break down during the laying. By changing the coulter installation angle to the horizon and the distance between the wheel of the sealing device and the shank, you can sow the seeds, if necessary, by the ridge method or into the groove along the axis of the row. In addition, when sowing seeds with the proposed coulter, it is possible to reduce the number of pre-sowing operations for tillage on lO / S and reduce the seeding rate during the formation of plant density per 1 ha by 20%. Claim 1. Seed opener, including lumpy body, skid, sem wire, and sealing device, in order to ensure seeding and embedment of seeds to a given depth regardless of changes in the field surface topography and ensuring the required contact seed, the coulter is provided with a paw plate, which is fixed along its longitudinal axis of symmetry on the lower edge of the skid perpendicular to its surface, while the paw plate is made with a narrowed back part, over which each other Sem become conductive and sealing -device. 2. The soshni to p. 1, which is also distinguished by the fact that the narrowed back part of the paw-plate is made curved with the end bent down, and on both sides on the plane of the lamella plate facing down, the subsoil blades are installed, orientate 59863216 bathrooms to the narrowed back of the la-1.
