Description

(54) BOWLER OF SMALL SEEDS

one

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to the openers of finely grained seeds, such as rice, alfalfa, etc.

Known openers of finely harvested seeds, containing an opener with a socket for directing seeds, behind which the soil guides of the busters 1 are installed on either side.

The disadvantage of these coulters is that the free space between the soil guides of the porter suggests the possibility of formation of uneven thickness and density of soil over the seeds, leading to uneven embedment of depth and low germination of seeds.

The purpose of the invention is to increase the uniformity of the density and thickness of the soil layer over the seeds.

The goal is achieved by installing a ski-shaped elastic plate with a u-shaped cutout symmetrical to the track of the coulter in the rear lower part of the opener hinge, with the soil guides installed in the bottom of the plate on both sides of the u-shaped notch.

FIG. I schematically shows the side view of the crop; in fig. 2 - opener, side view; in fig. 3 - ski plate J with soil guides, axonometric view.

The boxer has an arm 1 with a socket m 2 connected to this seven wire 3, installed under the sowing unit, a bunker with 4 sows. The back lower part of the length of the pipe 2 is fixed with a ski-shaped elastic plate 5, which has an u-shaped notch 6 in the rear part, and on both sides of the u-shaped groove to the r - ti - plate, the guides 7 of the soil are fixed.

The opener works as follows.

When moving, the openers 1 of the openers cut the grooves H; J, the depth is eaten away, simultaneously along this wire 3 with seed, chz of the bunker 4 enter the grooves:,;: this bouncing the seeds for .ii; i the grooves prevents rastphba from the rear side the vertical wall of the plate 5, which, at one time, provides

in its lower part, seeding is inserted into the furrow. The plate 5, having a width in the lower part of 0.80-0-0.96 from the step of the coulters, will mix the soil in the quantity necessary to ensure the seed placement in each groove in the individual SPF and, therefore, across the entire working width of the seed. The soil guides 7 of the zagortachs, reinforced but both sides of the notch 6 of the plate 5, change their position in height during movement of the coulter, i.e. due to the elasticity of the material the plate 5 with the soil grips of the 7 zagorucha copies the microrelief of the floor, thereby controlling the amount of unmixed soil for embedding seeds.

Depending on the state of the soil (density, humidity, composition, etc.) and the elastic properties of the ski plate 5. Fia soil guides 7 let the node absorb excess soil or delay the night and send it to the seed embedding zone when it is deficient. The presence in the plate of 5 G1-shaped notch 6 prevents the formation of a prism of a drag in front of the soil guide of the overcrowder (the soil passes through the cut-out), thereby excluding the clogging of the neck by the soil.

The presence of an elastic ski plate 5 with an H-shaped notch ensures that the layer is uniform in density and thicker over the seeds, which results in a uniform embedment of the seeds in depth and a good degree of semblance of seeds.
