RU217640U1 - 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 the convex side of the disks is covered with a web of a mesh harrow with spring teeth outward, welded to the disks along their perimeter by spot welding. 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, the convex side of the disks is covered with a web of a mesh harrow with spring teeth outward, welded to the disks along their perimeter by spot welding.

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 disc closing device with elastic elements [RF 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 [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 into rows with onion sets, which reduces the quality of onion placement in the furrow. 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 the convex side of the disks is covered with a web of a mesh harrow with spring teeth outward, welded to the disks along their perimeter by spot welding.

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 the convex side of the disks 5 is covered with a mesh harrow blade 6 with spring teeth outward, welded to the disks along their perimeter by spot welding.

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 and closing the onion sets in the furrow, without changing its original position. As a result, high-quality embedding of the bulbs in the furrow with loose soil without large lumps is achieved, which contributes to the uniformity of seedlings, and as a result, allows to increase the yield.
