RU217515U1 - SHEETER FOR SOWING GRAIN CROPS - Google Patents

Abstract

The utility model relates to agricultural engineering, in particular to seeding units used for guiding and placing seeds.

The technical result of the utility model is to improve the quality of work.

The technical result is achieved due to the fact that between the ends of the U-shaped bracket there is a rubberized roller made of a metal pipe with discs welded at the ends and half shafts with threads at the ends inserted into bushings placed in oblong holes at the ends of the U-shaped bracket with the ability to move along height and fixing in various positions with nuts.

Coulter for sowing grain crops, including a stand, to the base of which an lancet paw is attached, a seed duct made in the form of a hollow tube of square cross section, installed with the possibility of vertical movement along the tine and a U-shaped bracket attached to the lower part of the seed duct, the ends of which are directed to the side , opposite to the direction of movement of the coulter, and between the ends of the U-shaped bracket there is a rubberized roller made of a metal pipe with disks welded at the ends and semi-axes with threads at the ends inserted into bushings placed in oblong holes at the ends of the U-shaped bracket with the possibility of moving in height and fixing in various positions with nuts.

Description

The utility model relates to agricultural engineering, in particular to seeding units used for guiding and placing seeds.

Known openers grain seeder [Author's certificate RU patent No. 2293460, IPC class. А01С 7/00, А01С 7/20, 2007], containing racks mounted with an inclination back in the direction of movement and made of pipes, the upper end of which is fixed in bearing assemblies, which are installed in brackets mounted on a frame, fixed at the lower ends of the racks with a convex side spherical discs, the cut plane of which is perpendicular to the axis of the rack, and the rear edge of the discs is raised by 20 mm to ensure free passage of seeds.

However, the well-known sowing unit has a drawback, which includes the low quality of sowing crops due to the uneven distribution of seeds under the coulter.

The closest analogue to the claimed is the coulter of the combined seeding unit [Author's certificate RU patent No. 204465, IPC class. А01С 7/06, А01В 49/06, 2022], which includes a rack, to the base of which an lancet paw is attached, a seed duct made in the form of a hollow tube of square cross section, installed with the possibility of vertical movement along the rack and attached to the lower part of the seed duct U-shaped bracket, the ends of which are directed in the direction opposite to the direction of movement of the coulter.

The disadvantage of this design is the low quality of work. Semyatukovod, located above the cutting edges of the lancet paw, lays the seeds on a loose soil layer descending from the working surface of the lancet paw. In this case, insufficient contact of seeds with the soil is formed, due to which there is a delay and uneven germination.

The technical result of the utility model is to improve the quality of work.

The technical result is achieved due to the fact that between the ends of the U-shaped bracket there is a rubberized roller made of a metal pipe with discs welded at the ends and half shafts with threads at the ends inserted into bushings placed in oblong holes at the ends of the U-shaped bracket with the ability to move along height and fixing in various positions with nuts.

The specified set of essential features ensures the appearance of the proposed coulter for sowing crops of new properties that are different from the prototype.

Thus, the claimed features of the utility model meet the criterion of "novelty".

In FIG. 1 shows a diagram of a coulter for sowing grain crops, side view, in Fig. 2 - view A in Fig. 1.

A coulter for sowing grain crops, including a rack 2, to the base of which an lancet paw 1 is attached, a seed duct 8, made in the form of a hollow tube of square cross section, installed with the possibility of vertical movement along the rack and a U-shaped bracket 10 attached to the bottom of the seed duct, the ends which are directed in the direction opposite to the direction of movement of the coulter, and between the ends of the U-shaped bracket 10 there is a rubberized roller 11 from a metal pipe 12, Fig. 2, with disks 14 welded on the ends and semi-axes 15 with threads on the ends, inserted into bushings 17, placed in oblong holes 9 at the ends of the U-shaped bracket with the possibility of moving in height and fixing in various positions with nuts 16.

Coulter for sowing grain crops works as follows.

Before work, depending on the depth of sowing and the type of soil, the fertilizer seed tube 8 is set to a predetermined position in height, combining the corresponding holes 6 in the bracket 3 of the rack and the holes 7 in the bracket 5 of the fertilizer seed tube and fixing with a bolt and nut 4. Then set to a predetermined position in height rubberized roller 11, moving its axle shafts 15 in an oblong hole 9 and fixing with nuts 16.

When the claimed opener moves in the soil, the lancet paw 1 loosens the soil and cuts weeds. The loosened soil enters the location area of the seed duct 8. The U-shaped bracket 10 forms a groove for seeds in the loose soil and protects it with its sides from premature falling asleep. Semyatukovod 8, Fig. 1 guides and places the seeds in the formed groove, and the rubberized roller 11 compacts the soil at the bottom of the groove and presses the seeds into it. This increases the contact of each seed with the soil, which reduces the time of emergence of seedlings and increases their uniform development. The elastic rubber coating of the roller 13 prevents injury to the seeds. The above factors improve the quality of sowing.

Thus, the claimed technical result is achieved.
