RU66146U1 - PRECISION SEEDING SECTION - Google Patents

Abstract

The utility model relates to the working bodies of seeders designed for sowing seeds of row crops in the soil. The precision seeder section includes a combined fertilizer coulter with a cultivating paw and a lump secured to a hollow vas deferens, supporting runner, seed coulter, furrow rollers and 2ill stubblers.

Description

The utility model relates to agricultural engineering, in particular, to the working bodies of seeders designed for planting seeds of row crops in the soil.

A device for the formation and embedment of furrows during sowing of seeds is known, which includes successively lumping working bodies, a coulter with a plate runner fixed to it, a roller compactor and screwdrivers (SU No. 677703 class A01C 7/20 08/05/79).

Closest to the utility model is a sowing section, including a coulter containing a stand, a support runner and two cheeks with furrow bottom seals that are located at different levels. (SU No. 1611246 class. А01С 7/20 12/07/90).

During operation, the device rests on a runner and forms a groove. The wings of the rake diverts the topsoil into the aisles, and the earthenware mounted on the coulter dump covers the groove with seeds in the soil.

The disadvantage of this device is that the runner is significantly shifted forward relative to the point of ejection of seeds into the furrow, which slightly affects the quality of copying the relief. Thus, the device does not provide the possibility of obtaining high field germination of seeds.

The task is to improve the quality of copying the relief and increase the uniformity of the depth of seed placement.

EFFECT: provision of the required depth and quality of seed placement required by agricultural technology, increase of their field germination.

The technical result is achieved by the fact that in the section of the precision seeder, containing a combined fertilizer coulter with a cultivating paw and lump, support runner, seed coulter and shorting with furrow coils, the support runner is located on the sides of the seed cheeks

the coulter in the seed ejection zone and is rigidly mounted on the metering unit body, the fertilizer coulter is also rigidly mounted relative to the runner to level the soil in front of it, and furrow coils are mounted on a pivotally mounted spring-loaded frame with the possibility of changing the installation angle in the longitudinally vertical plane.

Figure 1 shows a section of a precision seeder; figure 2, view A in figure 1.

The precision seeder section includes a combined fertilizer coulter 1, made in the form of a cultivating paw 2, mounted on a hollow stand-seed tube 5, under the outlet of which there is a mineral fertilizer flow divider 4, which is two curved surfaces described by an equation of the form у = а · е ^{-λ · | x |} ; the fertilizer coulter is also equipped with a lump 3, which is mounted on the stand and consists of two plates placed on the rib, converging in front, and symmetrically directed back and to the side from the axis of symmetry of the opener, with the lower edge of the lump located parallel to the edge of the leg parallel to the field surface; the fertilizer stand with the help of the bracket 15 is rigidly mounted on the metering device body, the seed coulter 10 with a restrictive runner 8, rigidly fixed on the metering device body, two furrow rollers 13 mounted on a pivotally mounted spring frame 16 located at an angle to the direction of movement in the longitudinal vertical plane and zagortachi 14.

Section seeder precision sowing works as follows.

During the transfer of the section to the working position, the coulter 10 penetrates the soil to a depth limited by the reference runner 8. When the seeder 2 of the fertilizer coulter 1 moves, the soil loosens in front of the coulter, while fertilizers are applied to both sides of the row of seeds and 1-2 cm deeper , the lump 3 removes large clods from zone 6 in the row-spacing, the support runner 8 follows the fertilizer coulter 1, compacts and levels the field surface to a width of 7 in front of the seed coulter, the opener 10 is buried in the soil on

the depth limited by the support runner 8. Due to the rigid fastening of the support runner, the seed placement depth in the furrow is kept constant, and since the runner is located in the transverse plane opposite the coulter, the stability of the seed coulter travel depth is improved, since it copies the microrelief in the zone of movement of the seed coulter and the seeds are planted to the optimum depth in moist soil. At the same time, their field germination is increased.

The seed coulter 10 opens a furrow with a width of 12, into which the seeds are laid, sheltering with a layer of moist soil, crumbled from the walls of the furrow. The final closing of seeds with soil is carried out by furrow coils 13 and zagortachki 14.

If it is necessary to change the depth of mineral fertilizers and the position of the paw relative to the runner, the rack-vas deferens 5 can move up and down in the holder. The reference runner for adjusting the seed placement depth also moves along the longitudinal grooves of the brackets in a vertical plane.
