SU1253452A1 - Disk coulter - Google Patents

Description

eleven

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, seed coulters for sowing various agricultural crops.

The purpose of the invention is to increase the uniformity of embedding seeds in the soil by eliminating their removal from the furrow and spreading it over the soil surface.

FIG. 1 shows the opener, side view; in fig. 2 - the same section.

The opener comprises a housing 1, a seed head 2, two disks mounted at an angle to each other, made of movable 3 and fixed 4 internal parts.

For fixing the fixed parts 4 of the discs on the housing 1 in them in the center there are holes of hexagonal shape, and the protrusions on the housing 1 on which these parts are put on are made in the form of hexagons. The reduction of friction between the fixed 4 and rotating 3 parts in them is made of diametrically grooves 5 in which the balls 6 are placed.

When the coulter operates, the outer portions 3 roll over in the soil, forming a groove. Seeds along guide 2 move in the direction of a line of similarly 5 NIN disk parts 4, while some of the seeds fall into the groove, do not touch the disk parts 4, and the other part of the seeds fall into it, sliding along the disk parts 4 or bouncing off of them. In view of the fact that the seeds in contact with the opener only touch disk parts 4, which are stationary, the removal of seeds from the grooves and their spreading on the soil surface by rotating moving parts 3 is excluded. In addition, part 4 of the disk increases the structural strength, guides on which the disk parts 3 rotate. Therefore, the latter can be made of a smaller thickness and of a less rigid material than part 4 of the disk, for example, of plastic, which saves metal, as the disk parts 4 have smaller dimensions ry than disk parts 3.

The use of the opener of the proposed design ensures uniform embedding into the soil of all seeds and, consequently, increasing the yield of the sown crop.
