RU123624U1 - WORKING BODY FOR LOWING SOFT SOIL WITH THE BEST PRESERVATION OF VEGETABLE RESIDUES ON THE SURFACE SURFACE - Google Patents

Abstract

1. A device for loosening the plow sole, containing a working body including a stand, a blade and a ploughshare, characterized in that it further comprises a subsoiler rack with a knife and a chisel fixed to the working body. The device according to claim 1, characterized in that the chisel and knife of the working body are removable. 3. The device according to claim 1, characterized in that the working body is installed with the ability to change its position vertically, which allows you to change the depth of tillage.

Description

The utility model relates to devices for deep loosening of the soil.

A device for tillage is known (RU 95119488, publication date of 10/20/1997). Taken as a prototype. The prototype, like the claimed device, contains a stand, and the bit is designed for loosening and cutting the soil. The working body includes a vertical stand and a loosening-cutting element connected to it, characterized in that the loosening-cutting element is made in the form of tiered uneven flat knives with cutting edges on the front part, mated with a vertical side knife, the blade of which is turned to the side knives, and its cutting edge is inclined to the direction of movement at an angle of 50 ± 70 °, while the cutting edge of the blade of a flat knife of the upper tier has an angle of inclination in the plane of the side knife of 60 ± 5 °, and the cutting edge Single blade flat lower tier blade is inclined to the plane of the side cutter 45 ± 5 °, where the vertical face on the side of the knife front strut is formed visor portion formed by local deformation of the side surface of the blade towards the front strut placing fasteners.

A disadvantage of the analogue is that the stand with a loosening-cutting element with a cultivator is a complex structure, as well as the loosening and cutting elements of the working body quickly wear out as a result of the unit working on the field, and it is impossible to quickly replace them. In the presented utility model, this drawback is eliminated, since the chisel and knife are replaced.

The author was faced with the task of creating an inexpensive, easy to manufacture and operate device for deep loosening of the soil. EFFECT: improved soil structure, cutting of the deep roots of plants, soil cleavage.

To solve this problem and achieve the above technical result, a device was used that contains a working body, including a stand, blade and ploughshare, characterized in that it further comprises a subsoiler rack with a knife and a chisel attached to the working body.

Advantages of the above construction:

A device for loosening the plow sole provides the destruction of the "plow sole", structuring the soil and helps to restore the permeability of the whole loosened layer. The working elements - knife, blade and chisel, are removable. The utility model relates to tools of energy-saving technologies and agriculture, in particular to the processing of arable and subsurface horizons of the soil.

Disclosure of a utility model.

The device comprises a stand (2), on the front part of which a removable and prism-shaped knife (5) is fixed. A chisel (6) is mounted in the lower part of the rack, fixed by means of standard parts. At the rear of the bit (6), the lower end of the knife (5) is placed. The front of the rack (2) with the cutting edge of the knife (5) is inclined to the horizontal at an angle of 35-45 ° degrees. The bit sharpening angle (6) is 21 ° degrees. The angle of the cone is 120 + 10 ° degrees. Carbide elements of the bit (6) are made of hard alloy - Sormait. The stand is mounted on the plow body using bolts and brackets (7). The distance between the brackets is 10 cm. The step between the holes of the stand is 5 cm, which allows you to move the stand relative to the body in height from 0 to 20 cm. The plow body includes a ploughshare (3) and a removable blade (4).

Fig. 1. Scheme Devices for loosening the plow sole. 1 - SibIME stand, 2 - stand (working body), 3 - ploughshare, 4 - blade, 5 - knife, 6 - chisel, 7 - brackets.

The device operates as follows.

When moving the working body, the ploughshare (3) and the blade (4), destroy the soil layer in horizontal and vertical planes. The chisel (6) of the rack (2) loosens the plow sole to a depth of 20 cm. The knife (5) cuts the soil into vertical parts, while the plow sole is fastened intensively. The root residues of perennial grasses glide along the cutting edge of the knife (5). Due to the curvature of the edge, the root residues are cut, resulting in self-cleaning of the rack (2). When loosening, the chisel (6) exposes the cutting edge of the knife (5), which is rounded at the edges, which increases its deepening ability, thus, the chisel (6) is self-sharpening.

All adjustments of the plow with new working bodies, the procedure for preparing for work, and its maintenance are preserved. The depth of the processed layer below the share (3) can be changed by moving the rack (2) by moving up and down between the brackets (7).

Claims (3)

1. Device for loosening the plow sole, containing a working body, including a stand, a blade and a ploughshare, characterized in that it further comprises a subsoiler rack mounted on a working body with a knife and a chisel. 2. The device according to claim 1, characterized in that the chisel and knife of the working body are removable. 3. The device according to claim 1, characterized in that the working body is installed with the ability to change its position vertically, which allows you to change the depth of tillage.
