RU2490851C1 - Device of disk type for embedding bulbs in furrow - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: embedding body is a convex spherical disc with a cutting edge, on the working surface of which the circular holes with soil-guides are made, located on the inner surface of the disc. The generator of the soil-guides is deflected from the radial direction at an angle of not less than 5°. The angle of curvature of the surface profile of the soil-guides between the tangent at each point and the direction of flight of the particles is 2-3° greater than the angle of friction of the soil.

EFFECT: invention enables to improve the quality of embedding the bulbs on the surface of the soil-guide.

Description

The invention relates to agricultural machinery.

Known disk sealing organ of a potato planter sprouted potato tubers SAYA-4 (Khalansky V.M., Gorbachev I.V. Agricultural machines. - M .: KolosS, 2003. - 624 pp., Ill. - (Textbooks and textbooks for students higher educational institutions)).

A disadvantage of the known design of the embedment organ is that the design does not provide orientation of the tuber in the furrow with the sprouts up, as it affects the tuber after laying it in the furrow, which causes irregularity of seedlings and significantly reduces yield.

Known ridge seeder (AS USSR No. 946430, ridge seeder, IPC A01C 7/00, 1982). The closing organs of which are made in the form of spherical disks pivotally mounted on spring-loaded leashes.

The disadvantage of this disk seeding organ is the low quality of the seeds, which is expressed in the random distribution of seeds on the surface of the ridge and the uneven thickness of the sprinkled soil seeds, which leads to uneven seedlings and thickening (or sparseness) of the plants in individual sections of the ridge.

Known disk potter-seeding organ (USA, Application No. 1893512, US priority CL A01C 9/00, 1933.)

The disadvantage of this sealing body is that when the tubers are fed to the bottom of the furrow, they roll along it and thereby violate the distance specified by the agrotechnical requirements between them along the length of the furrow. This leads to malnutrition of tubers and, as a rule, to a decrease in yield.

Closest to the technical nature of the claimed invention (prototype) is a disk closing organ of a planting machine for planting root tubers, such as potatoes, garlic, onion sets, beet root liquor, made in the form of disk shorting (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 sealed with disk closing organs that act on the tuber, and due to the rotation of the disks, a longitudinal force arises in the area of their contact with the ground, tending to shift the soil with the tubers in the longitudinal direction and thereby violating the distance specified by the agrotechnical requirements between them along the furrow length and the necessary orientation of the tubers. This leads to malnutrition of tubers and, as a rule, to a decrease in yield.

The claimed invention is aimed at eliminating the above-mentioned disadvantages, improving the quality of the onions.

The problem is solved in that in the proposed disk sealing organ, the working surface of the convex spherical disk is made with round holes and soil guides located on the inner surface of the disk, and the generatrix of the soil guides deviated from the radial direction by an angle β equal to at least 5 °, and the profile curvature angle the surface of the soil guide α at each point of the curve of the surface of the soil guide between the tangent at each point and the direction of movement of the particles should be 2-3 ° more SFA soil sliding friction surface pochvonapravitelya φ.

The remaining features of the claimed device are private, since they characterize only the specific performance of a particular node.

The invention is illustrated by drawings.

Figure 1 shows the device of a convex spherical disk sealing body.

Figure 2 is a diagram of the operation of the disk sealing body in figure 1.

The disk sealing body consists of a convex spherical disk 1 with a cutting edge 2 and circular holes 3 located on the working surface of the disk 3 with soil guides 4 (Fig. 1).

Disk sealing body works as follows. When the machine moves across the field, a convex spherical disk 1 is buried in the soil to a depth h equal to at least 1 cm (figure 2). The convex spherical disk 1 of the embedment organ, when moving along the soil, engages with it, lifts it and feeds it to the soil guide 4. The soil guide directs it from above into the furrow. The hole 3 in the convex spherical disk 1 of the sealing organ contributes to the additional loosening of the soil, prevents sticking of the disk by the soil.

Compared with the prototype, the disk sealing organ provides high-quality soil sealing of the bulbs. Moreover, due to the fact that the working surface of the convex spherical disk is made with round holes and changes in the nature of the interaction between the guides and the soil, the bulbs are qualitatively sealed with soil, additional loosening of the soil is prevented by the soil sticking, and the generatrix of the guides is deviated from the radial direction by an angle β equal to at least 5 °, and the angle of curvature of the surface profile of the soil guide α at each point of the curve of the surface of the soil guide between the tangent in each th point and the direction of flight of the particles in motion should be 2-3 ° greater than the angle of friction of the soil on the surface pochvona ruler φ.
