The reel slots are made according to the shape of the ribs of the reel with grooves. Patent No. 2384040, published on 20.03.2010.

A solution is also known, which is a seeding device, including a housing with an open upper surface for loading seeds and two side walls, in which openings are made along one axis, in the first of which a clutch is located, and in the second - a grooved coil, made with the possibility of driving into rotation by the engine shaft, a shank, one end of which is located in the opening of the clutch, a socket, fixed with the possibility of rotation together with the grooved coil, and a spring-loaded valve fixed in the lower part of the housing with an adjusting bolt for adjusting the valve position. The second end of the shank has a chamfer and is made with the possibility of placement in an internal, corresponding in shape, opening of the grooved coil. Patent No. 183631, published on 09.28.2018.

The objective of the declared technical solution is to improve the design of the seeding apparatus to increase its reliability.

The technical result of the claimed solution consists in increasing the reliability of the seeding apparatus.

Improved technological efficiency is achieved, in particular, by increasing the durability of the seeding apparatus.

Increased durability is due, in particular, to the use of a minimum number of fasteners that violate the integrity of the structural elements of the product, eliminating the ingress of seed material, debris, dust and dirt into the gaps, which can lead to failure of the entire device.

The claimed technical result is achieved due to the fact that the seeding device includes a housing containing two side walls connected with the possibility of loading seeds into a cavity between them and unloading them from it, including through coaxial openings for placing in them a rotation shaft of a grooved coil installed in an opening of the side wall connected to a socket inserted into a collar with the possibility of rotation together with the coil relative to the housing, wherein the collar is secured between the side wall of the housing and a lining attached to the wall of the housing, wherein the collar is made of polyamide.

The fastening of the clip between the side wall of the housing and the plate attached to the wall of the housing ensures reliable fixation of the clip relative to the housing without the use of additional fasteners that violate its integrity, which could lead to a decrease in the durability of the product.

The cover plate protects the clip from the front side from external damage, and is also an element that ensures a reliable connection between the clip, body and socket, only by attaching the cover plate to the body.

The collar is a necessary element that ensures the tightness of the seeding unit, in particular, by preventing small-seeded material from spilling out through gaps and getting into the interior of the structure, as well as protecting the parts of the unit from dust and dirt when working in field conditions, which reduces wear of parts and, consequently, increases the service life of the product.

The polyamide frame is characterized by its wear resistance and durability, due to the strength and corrosion-resistant properties of the material. In addition, this material itself has high wear resistance and a low friction coefficient, which significantly reduces the wear rate when the polyamide frame slides over other elements of the structure, usually made of steel, which also significantly increases the service life of the seeding unit.

A housing containing two side walls connected with the possibility of loading seeds into a cavity between them and unloading them from it, including through coaxial openings for accommodating a shaft for rotating a grooved reel installed in an opening in the side wall, connected to a socket inserted into a collar with the possibility of rotating together with the reel relative to the housing, ensure reliable operation of the seeding apparatus as part of a seeder, characterize the device by the possibility of compact design and fastening the entire structure on a common shaft without using additional fasteners that violate the integrity of the structure.

A channel in the housing for removing fine dust contained in the seed material reduces wear on the parts of the seeding unit, further increasing its durability and reliability.

The presence of a groove for placing a corresponding protrusion in it, made on the overlay for fixing the clip on the side wall of the housing, provides a stop for the overlay to prevent shifts and friction of the overlay and clip relative to the housing under operating conditions, which can lead to microdamage to the surface of the structure, and, consequently, a decrease in its durability.

Further, the claimed technical solution is explained with the help of figures, which conventionally represent one of the preferred variants of the sowing apparatus.

Fig. 1-2 shows a general view of the seeding apparatus.

Fig. 3 shows a view of the clip from the inside (from the side where it is attached to the body).

Fig. 4 shows a view of the clip from the outside (from the side where it is attached to the overlay).

The numbers on the figures indicate:

body (1);

coil (2);

socket (3);

clip (4);

overlay (5);

channel (6) for dust removal;

groove (7) for placing the protrusion (8) of the cover (5) in it.

Below, one of the preferred embodiments of the claimed technical solution is described with references to figures.

The seeding apparatus includes a body (1) containing two side walls, preferably parallel to each other, connected with the possibility of loading seeds into the cavity between them and unloading them from it.

The walls include through coaxial holes for placing the motor shaft in it for rotating the grooved coil (2).

The coil (2) (Fig. 1) is installed in the opening of the side wall and connected to the socket (3) (Fig. 2), inserted into the holder (4) with the possibility of rotation together with the coil (2) relative to the housing (1).

Preferably, the collar (4) includes a recess corresponding to the peripheral edge of the socket (3) for securely connecting the parts, preventing the socket (3) from shifting from the axis.

The slots of the socket (3) preferably correspond in size to the protruding ribs forming the grooves of the coil (2) so that when the coil (2) is installed in the socket (3), the projections of the socket (3) fill the space of the grooves of the section of the coil (2) to prevent seeds from falling out of the housing (1) through the grooves.

The collar (4) is secured between the side wall of the housing (1) and the plate (5) attached to the wall of the housing (1).

The collar (4) is made of polyamide, preferably cast polyamide 610.

Preferably, the collar (4) includes a channel (6) for dust removal.

The clip (4) may also include a groove (7) for accommodating a corresponding protrusion (8) made on the plate (5) for fixing the clip (4) on the side wall of the housing (1).

For a person skilled in the art, it will be obvious that there are additional structural elements that ensure or improve the functionality of the seeding apparatus, such as a coupling for the reel, a crown of the fine-seeded reel, a valve, fasteners, and so on.

The seeding apparatus operates as follows.

The seeds flow by gravity from the hopper into the upper open part of the housing (1) of the seeding unit, are captured by a reel rotating on the drive shaft, and fill the space around the reel (1). Rotating, the reel (1) moves the seeds that have fallen into the grooves in the lower part of the housing of the seeding unit and drops them into the funnel of the seed pipe of the seeder. At the same time, from the side of the through holes in the walls, the inner part of the seeding unit is protected from dust, dirt and debris by means of a collar in which a socket is installed, fixed between the housing (1) and the cover (5).

The declared seeding unit can be used as a working element of a seeder for sowing grain and small-seeded crops. Depending on the purpose, the seeding unit can be made in different sizes, colors and configurations.

The presented figures, description of the design and use of the seeding device do not exhaust the possible design options and do not limit in any way the scope of the claimed technical solution. Other design options are possible within the scope of the claimed formula.
