RU2794965C1 - Device for planting onion bulbs in rigs - Google Patents

Abstract

FIELD: agricultural engineering.

SUBSTANCE: invention is related to working parts for planting onions using in machines for planting onion sets. The device for planting bulbs in the rigs contains two convex disks with a curved surface, installed with a convexity towards each other. The radius of curvature R of the disks is equal to half the diameter D of the disks. In this case, the minimum distance B between the convex parts of the disks, at the maximum angle of attack of the disks α, does not exceed four average diameters of onion sets of the second fraction.

EFFECT: invention makes it possible to improve the quality of embedding bulbs in the rigs and, as a result, the yield of onions.

Description

The invention 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) closing bodies, which are made in the form of spherical discs, pivotally mounted 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. MPK A01C 5/06. 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 A01C 5/06. 21.02.19, Bull. No. 6), which contains a frame with welded bearing housings, conical brushes with shells on the outer surface of which an elastic pile, covers and shafts of conical brushes. The disadvantage of this device is the complexity of the design and the need for additional mechanisms to drive the conical brushes.

Known disc closing body planting machine for planting root crops, such as potatoes, garlic, onion sets, beet mother liquor, made in the form of disc 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 claimed invention is aimed at eliminating the above-mentioned disadvantages, improving the quality of embedding bulbs.

The problem is solved by the fact that the proposed device for planting bulbs in the furrow consists of two convex disks with a curved surface installed with a convexity towards each other, and the radius of curvature of the disk R is equal to half the diameter of the disk D, while the minimum distance B between the convex parts of the disks is not more than four average diameters of onion sets of the second fraction at the maximum angle of attack of the disks α.

The invention is illustrated in FIG. 1 and 2. In FIG. 1 shows a diagram of a device for planting bulbs in a furrow. In FIG. 2 - front view.

The device for planting bulbs in the furrow contains two convex discs 1 with a curved surface mounted with a convexity towards each other, and the radius of curvature of the disc R is equal to half the diameter of the disc D, while the minimum distance B between the convex parts of the discs is not more than four average diameters of onion sets the second fraction at the maximum angle of attack of the disks α.

Device for planting bulbs in the furrow works as follows. When the planter moves across the field, a convex spherical disk 1 with a curved surface is buried in the soil (Fig. 2). The convex disk 1 with a curved surface of the closing device, when moving along the soil, engages with it and shifts it in the direction perpendicular to the furrow, thereby compressing the soil and closing the onion sets without changing its original position.

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

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