Description

The utility model relates to agricultural engineering, in particular, to seeders for sowing seeds of row crops.

Universal vegetable pneumatic seeders of the MSO series by MaterMacc are known [Vegetable pneumatic seeders of precision seeding [Electronic resource]. Access mode: https://agro-sistema.ru/index.php?option=com_content&id=60:2010-08-23-12-08-38.], intended for sowing all types of vegetable crops, containing a sowing section with a hopper for seeds, sowing device and coulter. The sowing sections of the seeders can be equipped with a microgranulator for applying starting doses of granular microfertilizers. Microgranulators make it possible to provide germinating seeds with all the necessary micro- and macronutrients in the required quantity during one of the most important stages of vegetation - the initial period of growth.

The disadvantage of the known seeders of the MaterMacc company is that the microgranulators for applying the starting doses of fertilizers have a complex design and are capable of sowing only expensive granular microfertilizers.

The closest analogue to the claimed is a row planter [Author's certificate RU patent No. 214578, IPC class. А01С 7/00, 2022], containing sowing sections connected to a common frame by means of a parallelogram-hinged mechanism, having a seed hopper, a sowing machine, an opener, a fertilizer hopper, a fertilizer dispenser, a fertilizer pipeline, and a fertilizer chopper equipped with an additional drive, including a housing with a window for feeding fertilizers, crushing elements and blades fixed inside the housing on a rotating shaft to create a directed air flow.

The disadvantage of this design is the lack of a device that provides regulation and maintenance of the uniformity of the depth of sowing seeds and fertilizers of various row crops in various soil conditions.

The technical result of the utility model is the possibility of adjusting to a given sowing depth while increasing the sowing depth uniformity.

The technical result is achieved due to the fact that the upper link of the parallelogram-hinged mechanism is connected to the bar of the common frame by a rod with holes attached to the link by means of a bracket and a bolt, passed with the possibility of sliding and turning through the hole of the bracket welded to the bar, with a spring put on it compression and two movable limiters, the upper limiter is put on above the bracket welded to the beam and fixed with a bolt in the corresponding hole of the rod with the possibility of rearrangement, the compression spring is put on below the bracket welded to the beam, rests with its upper end on the bracket and is limited from below by the lower limiter, fixed with a bolt in the corresponding hole rods with the possibility of permutation.

The specified set of essential features ensures the appearance of the inventive tilled seeder 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 row-crop seeder, side view.

A row-crop seeder containing connected to a common frame 5 by means of a parallelogram-hinged mechanism 2 sowing sections having a hopper 14 for seeds, a sowing machine 23, a coulter 1, a hopper for fertilizers 12, a fertilizer dispenser 13, a fertilizer duct 22, and a grinder equipped with an additional drive 11 fertilizers, including a housing 25 with a window 21 for feeding fertilizers, grinding elements 24 and blades 18 fixed inside the housing on a rotating shaft 20 to create a directed air flow, characterized in that the upper link of the parallelogram-hinged mechanism 2 is connected to the beam 6 of the common frame by a rod 8 with holes 17, attached to the link by means of a bracket 3 and a bolt 4, passed with the possibility of sliding and turning, through the hole of the bracket 7 welded to the bar 6, with a compression spring 15 and two movable stops put on it, the upper limiter 10 is put on above the one welded to the bar 6 of the bracket 7 and is fixed with a bolt 9 in the corresponding hole 17 of the rod 8 with the possibility of repositioning, the compression spring 15 is put on below the bracket 7 welded to the beam, rests with its upper end on the bracket 7 and is limited from below by the lower limiter 19, fixed by the bolt 16 in the corresponding hole of the rod 8 with the possibility of rearrangement.

Declared seeder tilled works as follows.

Before work, a predetermined sowing depth is set, for which the working length of the rod 8 is changed, which is hinged to the upper link of the parallelogram-articulated mechanism 2 using the bracket 3 and bolt 4, by aligning the corresponding hole 17 in the rod 8 with the hole in the upper limiter 10 and fixing it with a bolt 9 rotatable. Then, depending on the type of soil and the given sowing depth, the force of the initial compression of the spring 15 is set by moving the lower limiter 19 along the rod 8 and fixing it in the corresponding hole 17. For each type of soil and the given sowing depth, the optimal force of the initial compression of the spring is determined experimentally.

During operation, the seeds from the hopper 14 are fed by the sowing machine 23 into the furrow formed by the coulter 1. At the same time, the fertilizers from the hopper 12 through the dispenser 13 and the fertilizer line 22, through the window 21, enter the fertilizer grinder. Elements 24 crush the granules of fertilizer fertilizers to a powdery state and, in this form, are dumped into the same furrow, into the seed placement area. The directional air flow created by the blades 18 promotes the advancement of fertilizers in the grinder, prevents the adherence of fertilizer particles on the grinding elements 24 and the inner walls of the housing 25.

The compression spring 15, with its pre-compression force 15, deepens the coulter 1 to a given sowing depth, moving the rod 8 down until the upper limiter 10 stops in the bracket 7 and prevents changing the sowing depth with different soil resistance.
