RU217641U1 - DISC DEVICE FOR INCLUDING ONION SETS IN THE FURROW - Google Patents

Abstract

The utility model relates to the field of agricultural engineering, in particular to machines for planting onion sets, more precisely, to closing organs during planting.

The technical result of the utility model is to improve the quality of work on various soils.

The technical result is achieved due to the fact that behind the discs there is a smooth roller, the axis of which is attached by means of plain bearings to two bolted leashes, one of which is connected to the bracket through a torsion spring located in a cup welded to the bracket and limiting the rotation from below the jumper between the uprights.

A disk device for planting onion sets in a furrow, which includes a bracket made of a 40×25×4 corner, to which disk racks are attached with the ability to adjust the angle of attack, in which axles with rolling bearings are fixed, on which convex curvilinear disks are installed, moreover, behind the disks there is a smooth roller, the axis of which is attached by means of plain bearings to two bolted leashes, one of which is connected to the bracket through a torsion spring located in a cup welded to the bracket and limiting the rotation from below by a jumper between the uprights.

Description

The utility model relates to the field of agricultural engineering, in particular to machines for planting onion sets, more precisely, to closing organs during planting.

Known disk closing device with elastic elements [Author's certificate of the Russian Federation patent No. 189135, IPC class. A01D 07/18, 2019], which consists of a convex spherical disk with a cutting edge and soil guides located diametrically on the inner surface of the spherical disk, while the soil guides are made of a set of elastic elements rigidly connected to each other.

The disadvantage of the considered disk closing device is that when working on soil with different moisture content, a different number of elastic elements of the disk is required, which increases the complexity for re-equipment of the closing working body.

The closest analogue to the claimed is a disk device for planting onion sets in the furrow [Author's certificate RU patent No. 214396, IPC class. А01С 7/20, А01С 5/04, 2022], which includes a bracket made of a 40 × 25 × 4 angle, to which disk racks are attached with the ability to adjust the angle of attack, in which axles with rolling bearings are mounted, on which convex curved discs.

The disadvantage of this design is the low quality of work on cloddy soils of low moisture with poor pre-treatment. Disks with a smooth surface do not crush soil clods and fragments of soil crust, but shift them in rows with onion sets, without compacting the soil and pressing it against the bulbs from above, which reduces the quality of work.

The technical result of the utility model is to improve the quality of work on various soils.

The technical result is achieved due to the fact that behind the discs there is a smooth roller, the axis of which is attached by means of plain bearings to two bolted leashes, one of which is connected to the bracket through a torsion spring located in a cup welded to the bracket and limiting the rotation from below the jumper between the uprights.

The specified set of essential features ensures the appearance of the proposed disk device for planting onion sets in the furrow of new properties that are different from the prototype.

Thus, the claimed features of the utility model meet the criterion of "novelty".

In FIG. 1 shows a diagram of a disk device for planting onion sets in a furrow in a perspective view.

A disc device for planting onion sets in a furrow, including a bracket 1 made of a corner 40×25×4, to which stands 2 discs 5 are attached with the possibility of adjusting the angle of attack, in which axles 3 are fixed with rolling bearings 4, on which convex curvilinear disks 5 are installed, and behind the disks 5 there is a smooth roller 11, the axis 10 of which is attached by means of plain bearings to two bolted leashes 8, 9, one of which is connected to the bracket 1 through a torsion spring located in the cup 7 welded to the bracket 1 and limiting rotation from below jumper 6 between racks 2.

Disk device for planting onion sets in the furrow works as follows. When the planter moves, the convex curvilinear discs 5, rotating on rolling bearings 4 mounted on the axes 3 of the racks 2, penetrate the soil, engage with it, break up the clods and loosen the soil with the teeth of the mesh harrow, shift it in the direction perpendicular to the furrow, thereby compressing the soil from the sides and closing the onion sets in the furrow, without changing its original position. At the same time, the smooth roller 11, loaded with a torsion spring located in the cylinder 7, connected to the leash 8, compacts the soil in the row, pressing it against the bulbs from above and further destroys the soil clods.

As a result, the high-quality embedding of the bulbs in the furrow with soil without large lumps increases, which contributes to the uniformity of seedlings, and as a result, allows to increase the yield.
