Description

The invention relates to agricultural machinery, in particular to the vomers for broadband seeding of vegetable seeds. The purpose of the invention is to reduce the possibility of clogging in the soil between the discs and the leveling comb and to increase the stability of the seed embedment depth. The opener includes a housing 1, disks 2, a seed distributor 3, a leveling comb with teeth 4 and 5. The lateral teeth of the comb are mounted to the central tooth 5 at an angle β less than half the angle of the disk solution 2, and on the inner surface of the disks there are adjustable length stops 6. The rigidity of the lateral teeth 4 is less than the rigidity of the central tooth 5. During operation, the central tooth 5 loosens a mound in the middle of the Y-shaped groove, while the lateral teeth 4 level and compact the bottom of the furrow. When the disks 2 rotate, the side teeth 4, interacting with the stops 6, oscillate with respect to the bottom of the furrow and central tooth 5. At the same time, the comb teeth self-clean, the possibility of clogging the space between the discs by the soil decreases, the quality of leveling the bottom of the furrow improves, and as a result depth and area of the seeding strip. 1 hp f-ly, 4 ill.

The invention relates to agricultural machinery, in particular to openers for broadband seeding

vegetable crops.

The aim of the invention is to reduce the possibility of clogging of the soil between the discs and the comb and increase the stability of the seeding depth.

FIG. I schematically shows the opener for broadband seeding, rear view; in fig. 2 shows a section A -A in FIG. one; in fig. 3 section B - B in FIG. 1 (without body and seed distributor); in fig. 4 — node I in FIG. 3 (fastening adjustable stop to the disc coulter).

The opener for broadband sowing includes a housing 1, disks 2 fixed on it at an angle to each other, a seed distributor 3, as well as an arcuate comb with two lateral 4 and one central 5 elastic teeth. Central sb 5 is located in the longitudinal plane of the opener symmetry. The side teeth 4 are mounted to the central tooth 5 at an angle (4 less than half the angle of the discs a. The diameter of the bar material of the teeth 4 is less than the diameter of the bar of the tooth 5, which makes them less rigid. On the inner surface of the discs 2 perpendicular to their plane with lateral teeth 1, adjustable spores 6.

Before work, making the regulation of the depth of embedding of seeds by rearranging the comb with teeth 4 and 5 in height, and also adjusting the amplitude of oscillations of the side teeth 4 depending on the physical and mechanical properties of the soil by changing the length of the stops 6.

When the coulter moves, discs 2 open a \\ ’-shaped furrow. The central tooth 5, having increased rigidity, loosens a mound in the middle of the furrow. The side teeth 4, moving in the loose soil, level and compact the bottom of the furrow.

When the atom, having a small rigidity, the teeth 4 are deflected by the stops 6 incident on them, and after losing contact with them they return to their original position under the action of elastic forces of the material from which they are made. As a result, the teeth 4 self-clean and eliminate sticking by the soil of the central tooth 5.

Since the side teeth of the comb make forced vibrations, the soil is eliminated before the teeth, the possibility of clogging the space between the discs by the soil is reduced, which allows for a good leveling of the furrow in the cross section and, as a result, increasing the stability of embedding seeds in the depth and area of the seeding strip.

Claims (2)

Claim 1. Disc coulter for broadband seeding, comprising a housing, with disks fixed at an angle to each other, a seed distributor, a comb with elastic arcuate teeth made of a bar material, with the side teeth of the comb angled to the central tooth and made of a bar material of smaller diameter , different hem, that, in order to reduce the possibility of soil clogging the space between the discs and the comb and increase the stability of the seed embedment, the side teeth of the comb are located at prices The main tooth is at an angle less than half the angle of the disk solution, and on the inner surface of the vice, stops are installed with the possibility of sliding the axis with lateral teeth. 2. The opener by n. 1, different heme. In order to change the intensity of the impact of the side teeth on the loosened soil due to the change in the amplitude of their vibrations, the stops installed on the discs are adjustable in length. 1514262 fig-
