Description

The utility model relates to agricultural engineering, in particular to seeding machines for precision seeding.

Known reel sowing apparatus [Author's certificate RU patent No. 1107764, IPC class. А01С 7/04, А01С 7/12, 2004], consisting of a hopper, in the lower part of which there is a slot, a seeding coil on a horizontal shaft and an elastic seed reflector. On the cylindrical surface of the coil, rows of sowing elements are made in the form of cone-shaped recesses along the circumference. At the bottom of the body with an inclination, gutters are made according to the number of rows. Seeds are fed through the troughs into the receiving window of the ejector.

The disadvantages of the known coil sowing apparatus are:

the complexity of the design due to the presence of an air duct, which has no functional significance due to the fact that the seeds, rolling down the chute under their own weight, fall into the seed duct, and the air supply to them only increases the force acting on them, as a result, part of the seeds will inevitably receive mechanical damage as a result of hitting the walls of the seed tube and each other due to the increased force acting on them;

lack of high partitions between the chutes and the seeding spool, as a result of which, when the seeder moves, part of the seeds supplied by the spool will fall into another chute, and the seeding uniformity in the rows will be disturbed, this will especially affect when working on hilly terrain;

lack of nesting function.

The closest analogue to the claimed is a seeding machine [Author's certificate RU patent No. 212740, IPC class. А01С 7/04, А01С 7/00, 2022], containing a housing with a coil installed in it on a horizontal shaft with elements made on its cylindrical surface for capturing seeds in the form of rows of cone-shaped recesses located along a screw guide with a step equal to the row spacing for sown agricultural crops, a reflector located at an acute angle to the tangent circle of the cylindrical surface of the coil, plates adjacent with a gap to the cylindrical surface of the coil and a scraper for removing seeds from cone-shaped recesses in the upper part of the coil.

The disadvantage of this design is the low uniformity of seeding. The scraper removes stuck seeds from the cone-shaped recesses at the top of the spool. When individual seeds get stuck in cone-shaped recesses and do not fall out in the lower part of the coil, a gap occurs and the distance between adjacent seeds in a row increases. With the subsequent removal of the seeds stuck in the cone-shaped recesses with a scraper located in the upper part of the coil, the removed seeds roll along the plate 10 into the seed tube, join the seeds that fall out at this point in time from the cone-shaped recesses in the lower part of the coil, and the distance between the sown seeds in the row decreases . In addition, there is no nesting function.

The technical result of the utility model is the emergence of a new nested sowing function with increased sowing accuracy and the possibility of changing the number of seeds sown in the nest.

The technical result is achieved due to the fact that the cone-shaped recesses are located along three annular guides in such an order that on each coil generatrix spaced at the same distance from each other there are three holes equidistant from each other, annular grooves are made on the outside of the coil body, passing through the middle of the rows of cone-shaped recesses to their entire depth, and wedge-shaped lamellar seed ejectors are inserted into each groove in the lower part of the coil, welded to the plate installed under the scraper.

The specified set of essential features ensures the appearance of the proposed sowing apparatus for nested sowing 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 sowing apparatus for nested sowing when interacting with seeds, side view;

in fig. 2 - a diagram of a sowing coil in a perspective view.

Seeding apparatus for nested sowing, containing a housing 5 with a coil 9 installed in it on a horizontal shaft 3 with elements made on its cylindrical surface for capturing seeds 12 in the form of rows of cone-shaped recesses 8, a reflector 4 located at an acute angle to the tangent circle of the cylindrical surface of the coil , plates 2, 10 adjacent with a gap to the cylindrical surface of the coil and a scraper 6 for removing seeds from cone-shaped recesses, moreover, cone-shaped recesses 8 are located along three annular guides in such an order that on each spaced at the same distance from each other at the same distance forming 13 of the coil cylinder there are three recesses 8 equidistant from each other, annular grooves 7 are made on the outside of the coil body, passing through the middle of the rows of cone-shaped recesses 8 to their entire depth, and wedge-shaped lamellar seed ejectors 11 are inserted into each groove in the lower part of the coil, welded to the installed under scraper plate 10.

The operation of the sowing machine is carried out as follows.

Seeds from the hopper flow by gravity into its lower part, where a seed reflector 4 is installed, which does not allow the seeds to remain at rest, but constantly moves them down, where they fall into the cone-shaped recesses 8 of the seeding coil 9. Then the seeds are carried away by the cone-shaped recesses 8 of the seeding coils 9 move to the lower part of the sowing machine and are dropped by wedge-shaped lamellar ejectors 11 placed in the annular grooves 7 into the receiving socket 1 of the skid coulter. With the help of the pressure plate 2, the seeds do not fall out of the cone-shaped recesses during the movement. Scraper 6 cleans the outer surface of the coil from adhering particles and dumps them into the seed tube 8.

The claimed layout of the cone-shaped recesses on the surface of the coil provides the dropping of three seeds simultaneously through the same angle of rotation of the coil. The distance between seed nests in a row is adjusted using a seeder gearbox of known design (not shown).

Since the ejectors 11 reliably remove the seeds from each cone-shaped recess 8 in the lower position of the coil without gaps, the same number of sown seeds in the nest is ensured, i.e. their uniform distribution.

The claimed design also makes it possible to reduce the number of seeds in the nest to two by plugging one of the annular grooves with 7 lamellar semirings.

Thus, the claimed technical result is achieved.
