Abstract

FIELD: agriculture.

SUBSTANCE: ploughshare comprises centre hoe with installed stand and hollow seed drill tube, roller. Hollow seed drill tube is rigidly connected to stand of centre hoe, lower part of seed drill tube is directed to the side opposite to direction of centre hoe motion. Centre hoe is equipped with flat disks installed on brackets symmetrically at both lateral sides of centre hoe with the possibilities to adjust angle of attack of flat disks and variation of their installation height. Roller is arranged in the form of two truncated cones. Roller is installed on brackets with hinged joints and vertical rod, with the possibilities to control distance between truncated cones and position of roller in vertical plane.

EFFECT: improved quality of earth ridge compaction with density specified by agrotechnical requirements.

Description

The invention relates to agricultural machinery, in particular to the openers of seeders.

Known opener [1], including lancet paw with a hollow rack-vas deferens and a back shelf mounted on it, forming a closed screening chamber, in which a passive seed distributor is installed. In the front of the rack of the vas deferens above the surface of the lancet paw perpendicular to the direction of movement of the coulter, a paddle activator is installed. It is a shaft with eight blades, the working ends of which are made with a slope from horizontal to the side surface of the rack-vas deferens. The drive of the paddle activator is carried out by a chain transmission from the shaft of the support-rolling roller. The linear speed of the working ends of the blades is 1.1-1.4 times greater than the translational speed of the supporting-rolling roller. The surface of the supporting-rolling roller in order to reduce slippage is made with tillers.

However, the known device has several disadvantages, which include:

- uneven seed placement;

- uneven soil compaction.

The purpose of the invention is improving the quality of sowing.

This goal is achieved by the fact that the hollow vas deferens are rigidly connected to the rack of the lancet paw. The lower part of the vas deferens is directed in the direction opposite to the direction of movement of the lancet paw. The lancet paw is equipped with flat disks mounted on brackets symmetrically on both sides of the lancet paw with the ability to control the angle of attack of the flat disks and change the height of their installation. The roller is made in the form of two truncated cones and mounted on brackets with hinges and a vertical rod, with the ability to control the distance between the truncated cones and the position of the roller in the vertical plane.

Figure 1 shows the opener, side view, figure 2 is the same, top view, figure 3 is the same, rear view.

The coulter contains a lancet paw 1, a rack 2 and a hollow vas deferens 3. The hollow vas deferens 3 is rigidly connected to the rack 2 of the lancet paws 1 by means of plates 4. The lancet paw 1 is provided with flat disks 5 that are mounted on brackets 6 symmetrically on both sides of the paw 1 with capabilities adjusting the angle of attack of the flat discs 5 to the direction of movement of the lancet paw 1, as well as changing the height of their installation. The required angle of attack of the flat shields 5 to the direction of movement of the unit is fixed in the desired position of the bracket 6 using the locking bolts 7 inserted into the holes 8 of the adjustment plate 9. The position of the flat disks 5 in height is set by moving the bracket 10 along the strut 2 of the pointed arm 1 with its subsequent fixation bolt 11. The roller is made in the form of two truncated cones 12. The truncated cones 12 are mounted on brackets 13 with hinges 14 and a vertical rod 15, and the roller is mounted under the vertical rod 15 on the transverse axis 16. Neobkh dimoe distance between the truncated cones 12 regulate the sliding movement of the half-axles 17 of the transverse axis 16 and fix in position a bolt 18 with a nut 19. The vertical rod 15, a spring 20. By the spring 20 ensures a pressure change of the truncated cones 12 on the sides of the soil ridge.

The coulter also contains a bracket 21, mounted on the rack 2 of the lancet paw 1. A guide 22 of the rod 15 is rigidly attached to the bracket 21. A nut 23 is mounted on the rod 15, with the possibility of moving along it. The nut 23, when moving along the rod 15, changes the compression force of the spring 20 that allows you to adjust the pressure of the truncated cones 12 on the sides of the soil ridge. For reliable fixation of the rod 15 during operation of the coulter or during its transportation, a nut 24 is installed on the outer end of the rod 15.

The coulter works as follows. The required depth of the lancet paw 1 and the angle of attack of the flat discs 5 are pre-set using the locking bolts 7 inserted into the holes 8 of the adjustment plate 9. The position of the flat discs 5 in height is adjusted by moving the bracket 10 along the rack 2 of the lancet paw 1 and fixed with a locking bolt 11. Necessary the distance between the truncated cones is set by moving the sliding axle shafts 17 from the transverse axis 16 and fixed in position with a bolt 18 with a nut 19. By moving the nut 23 along the rod 15, the necessary dimoe force compression spring 20 to provide the desired pressure truncated cones 12 on the sides of the soil ridge.

When the coulter moves, the lancet paw 1 loosens the soil and cuts the weeds. At the same time, the lancet paw 1 removes the top soil layer, shifts it in the row-spacing and forms a compacted bed for laying seeds in it. Seeds are sown from the hollow vas deferens 3. Flat discs 5 going on both sides of the lancet paw 1 shift the soil to the sown seeds, thereby forming a tubercle of soil above them. The truncated cones 12 running behind the lancet paw 1 due to the pressure of the spring 20 uniformly compact the sides of the soil ridge.

Improving the quality of sowing is achieved by performing flat disks on both sides of the lancet paw, as well as spring-loaded truncated cones installed under a vertical bar, which exclude clogging of soil and plant residues of flat disks, uniformly compacting the soil ridge over sown seeds with a given density of agricultural requirements.
