Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The purpose of the invention is to reduce traction resistance, improve the uniformity of seeding material sown in depth by reducing the height of the untreated scallop of the furrow bottom and ensuring the self-cleaning of the vomer disks. The opener consists of a hollow post 1, to which eccentric bushes 2 and 3 are attached. On bushes 2 and 3, the lower 4 and upper 5 spherical disks are mounted, their axes of rotation are eccentric relative to the axis of the hollow post 1, shifted in opposite directions in the transverse plane. The angle between their axes is 2-10 °. A diffuser 7 is placed under the exit window 6 of the hollow rack 1. Disks 4 and 5 are provided with teeth 8 along the periphery. When the coulter moves, the cutting edge 8 of the disk 4 interacts with the soil, and the cutting edge 8 of the upper disk 5 on the other hand that provides rotation of the discs in opposite directions. The presence of the teeth of the cutting edge 8 ensures the reliability of self-rotating discs due to better adhesion to the soil and better cutting of plant residues, which reduces traction resistance. When moving the coulter, a furrow is formed, the bottom of which has a lower height of the scallops than in other similar coulters. The sown material through the hollow rack 1 enters the diffuser 7 and is evenly distributed along the bottom of the furrow.

Description

Field of the Invention The invention relates to agricultural machinery, mainly k coulters for subsurface spreading grain and other bulk materials.

The purpose of the invention is to reduce traction resistance, improve the uniformity of seeding material sown in depth by reducing the height of the untreated scallop of the furrow bottom and ensuring the self-cleaning of the vomer disks.

FIG. 1 shows a vomer, top view; in fig. 2 - section A - A in FIG. one; in fig. 3profile bottom of the furrow formed by single disc opener; in fig. 4 - the profile of the bottom of the furrow formed by the proposed opener.

The opener consists of a hollow stand 1, to which eccentric sleeves 2 and 3 are attached (phi1- 1 and 2). Spherical disks are mounted for rotation on the bushes of the lower 4 and 1) hp 5. The shape of the eccentric bushings ensures that the disk 5 is mounted above the disk 4 so that their rotation axes are eccentric in the transverse plane relative to the axis of the hollow rack 1, shifted in opposite directions and form an angle of | 10 between itself. ) of the hollow column 1 is placed a diffuser 7. Disks 4 and 5 have teeth 8 around the periphery.

(l pnik works with. 1 in the following way.

When ei o move, the cutting edge of the lower disk 4 interacts with the soil on one side of the coulter, and the cutting edge of the upper disk 5 on the other side, and as a result, the courage of the courier wheels in opposite directions is ensured. The rotation of the discs in opposite directions ensures the cutting of the soil on both sides of the opener by rolling, therefore, si, 1a friction sk1) the fit of the blade along the blade is replaced by the sy.10i friction k; 1x, which reduces the pulling resistance of the coulter. When the opener disks rotate in opposite directions, they are self-sensing.

but is distributed along the bottom of the furrow. The carved material from above is closed in the furrow by the soil coming from the discs 4 and 5 of the joint.

The presence of teeth 8 on the periphery of the discs increases the reliability of their self-rotation due to better engagement of the teeth with the soil, and at the same time, weeds are better cut by pinching them between the teeth of the upper and lower discs. Toothed discs also have less drag resistance than solid discs.

The height of the unbleached scallop of the furrow bottom at the vomer (Fig. 4) is lower than that of the coulters, made in the form of forcibly rotating spherical disks (Fig. 3). Consequently, the coulter provides more uniform in depth tillage and seeding of sown material.
