RU211887U1 - Disc organ for embedding onion sets - 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 disk body for embedding onion sets includes a bracket to which the disk racks are attached, in which axles with rolling bearings are fixed, on which convex curvilinear disks are installed. In this case, the bracket, made of a corner 40×25×4, contains a welded post, to which a connecting rod is attached with the help of bolts, pivotally fixed to the coulter by means of an axle. The utility model makes it possible to improve the quality of the placement of bulbs in the furrow and, as a result, the yield of onions.

Description

The utility model relates to agricultural engineering.

Known potato planter with disc closing bodies (utility model patent BY 2703 U 2006.04.30). A disadvantage of the well-known design of the closing body is that the design does not ensure the orientation of the planting material, as it affects the tuber after it is laid in the furrow.

Known ridge seeder (AS USSR No. 946430, ridge seeder, IPC A01C 7/00, 1982), the closing bodies of which are made in the form of spherical disks, hinged on spring-loaded leashes. The disadvantage of this disk closing body is that when planting seeds, the thickness of the sprinkled soil is not the same, which causes uneven seedlings.

A device with a conical brush for planting bulbs in a furrow is known (patent No. 2613460. RF. IPC A01 C5/06. 16.03.17, Bull. No. 8), containing a conical brush consisting of a conical clip, along the generatrix of which an elastic pile is fixed. The disadvantage of this device is that the necessary speed of rotation of the conical brush is not provided, and as a result, the amount of soil supplied by the conical brush into the furrow is different. This leads to uneven seedlings and reduced yields.

A device with conical brushes for planting bulbs in a furrow is known (patent No. 187135 of the Russian Federation. MPK A01 C5 / 06. 21.02.19, Bull. No. 6), which contains a frame with welded bearing housings, conical brushes with shells, on the outer surface of which is fixed elastic pile, covers and shafts of conical brushes. The disadvantages of this device are the complexity of the design and the need for additional mechanisms to drive the conical brushes.

Known disk closing body planting machine for planting root crops, such as potatoes, garlic, onion sets, beet mother liquor, made in the form of disk harrows (patent No. 2038730, Planting machine, IPC A01C 5/08, 1995). The disadvantage of this machine is that after laying the tubers on the bottom of the furrow, they are covered with disk closing bodies that act on the soil and shift the tuber in the longitudinal direction, thereby changing the distance between them along the length of the furrow, which leads to a decrease in yield.

A disk-type device for planting bulbs in a furrow is known (patent RU No. 2490851. 27.08.2013 Bull. No. 24). The closing body of the device is a convex spherical disk with a cutting edge, on the working surface of which there are round holes with soil guides located on the inner surface of the disk. The disadvantage of this device is that in the direction of travel, the depth of the disks is not the same, and as a result, the amount of soil supplied by the soil guides into the furrow is different. This leads to uneven seedlings and reduced yields.

The closest in technical essence to the claimed invention is a disk closing device with elastic elements (patent No. 189135 of the Russian Federation. IPC A01D 07/18. 13.05.19, Bull. No. 14), 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 proposed utility model is aimed at eliminating the above disadvantages, improving the quality of onion sets.

The problem is solved by the fact that the proposed disk body for embedding onion sets includes a bracket 1 to which the racks of the disk are attached, in which axles with rolling bearings are fixed, on which convex curvilinear disks are installed, differs in that the bracket 1 is made of a corner 40 ×25×4 and contains a welded post 2, to which a connecting rod 3 is attached with bolts, hinged to the coulter by means of an axis 4.

The utility model is illustrated in Fig.1. Figure 1 presents a three-dimensional model of the disc body for embedding onion sets.

The disk body for planting onion sets includes a bracket 1, to which the racks of the disc are attached, in which axles with rolling bearings are fixed, on which convex curvilinear discs are installed, while the bracket 1 is made of an angle 40 × 25 × 4 and contains a welded rack 2, to which a connecting rod 3 is attached with bolts, hinged to the coulter by means of an axle 4.

Disc body for planting onion sets works as follows.

When the planter moves, convex curvilinear discs, rotating on rolling bearings mounted on the axes of the disc racks, are buried in the soil. The convex curvilinear disks of the disk device for planting the onion sets in the furrow, when moving along the soil, engage with it and shift it in the direction perpendicular to the furrow, thereby compressing the soil and planting the onion sets in the furrow without changing its original position.

Compared with the prototype, the disk body for planting onion sets provides high-quality embedding of onion sets with soil in the furrow, additional soil loosening, and at the same time, sticking of the disk with soil is prevented.

As a result, high-quality placement of onion sets in the furrow is achieved, which contributes to the uniformity of seedlings, and as a result, allows to increase the yield of onions.
