RU55527U1 - MULTI-HOUSING PLOW - Google Patents

Abstract

The proposed utility model of a multi-body plow relates to agricultural engineering, in particular for subsurface tillage. The technical task is to improve the quality of soil cultivation while reducing the specific energy indicators of the unit. This technical problem is solved by the fact that in a plow containing a frame on which a row of plow bodies is mounted at an angle to the direction of travel, made of right and left-side lancet shares mounted on racks, of which the left-hand side is shorter than the right-hand share, and the share angle of the plowshares relative to the direction of movement makes 30 ... 60 hail. Using a plow allows you to reduce the height of the ridges of the soil, increase the uniformity of its crumbling and improve the energy performance of the arable unit.

Description

The proposed utility model relates to agricultural engineering, in particular to plows for subsurface tillage.

A multi-case plow is known, comprising a main frame and a transverse beam pivotally mounted on it by means of a hydraulic cylinder. The plow bodies are mounted on the beam by means of racks. The beam is made with lateral sides having longitudinal slots. The corners are made with oval holes corresponding to the aforementioned slots in the side walls. Plow bodies are attached to the sides by means of these corners (see RF patent No. 2195093, IPC A 01 B 15/14).

The disadvantage is that the furrow has a ridge bottom.

Known plow body designed for subsurface tillage. The body of the plow-ripper contains a rack having a vertical part and an inclined part. A shoe with a chisel and a field board, on which an additional share is articulated, is fixed below on an inclined part. The main share is installed on the working side of the inclined part, and on its back there is a one-sided paw, the cutting edge of which is located in the horizontal plane (see RF patent No. 2125777, IPC A 01 B 13/08).

However, the presence of a field board significantly increases the traction resistance of the plow.

Closest to the proposed solution is a multi-body plow for subsurface tillage, containing a frame on which two rows of plow bodies with plowshares are installed at an angle to the direction of movement (see USSR author's certificate No. 1426479, A 01 B 3/00).

The disadvantages of this design include the following:

- the presence of a field board significantly increases the traction resistance of the plow;

- behind racks of plow bodies unfinished furrows are formed, which reduces the quality of soil cultivation.

The technical problem posed before the utility model is to improve the quality of tillage while reducing the specific energy performance of the plow.

This technical problem is solved by the fact that in a multi-case plow containing a frame on which a row of plow bodies with plowshares is mounted at an angle to the direction of movement, plow bodies are made of right and left-side lancet shares mounted on racks, of which the left-hand ones are shorter than the right-hand and

located behind the rack, while the length of the left-hand share is not less than 1/3 of the length of the right-hand one, and the angles of the share relative to the direction of movement are 30 ... 60 degrees.

Useful, mod spruce is illustrated by drawings.

Figure 1 shows a plow, top view;

Figure 2 - plow body, top view;

Figure 3 is the same front view;

Figure 4 (a, b) - the treated soil.

The plow consists of a frame 1 with support wheels 2 and plow bodies 3. The plow bodies 3 comprise a rack 4, on which a right-hand share 6 and a left-hand 7 located behind the rack 4 are fixed by means of a plate 5. The shares 6 and 7 are removable and have two-sided sharpening, allowing when one working side is worn, use the other. The left-side (in the direction of travel) ploughshare 7 is shortened, and, as established experimentally, its length should be at least 1/3 of the right-handed 6, and the angles (γ) of setting the plowshares 6 and 7 with respect to the direction of movement are 30 ... 60 hail.

The plow works as follows:

When the aggregate moves, the shares 6 and 7 are buried in the soil to a depth of "a". At the same time, the loosened soil with the right-hand share 6 crumbles and lays on the bottom of the furrow, forming, when interacting with stand 4, the open part of the furrow “E”. (Figa)

The soil, loosened with a shortened ploughshare 7, encountering a ledge of untreated soil "G", due to the increase in volume, moves into the furrow "E", forming a loosened ridge structure of the soil. In this case, the shortened ploughshare 7 performs the function of a field board, and the forces P and P acting on the ploughshare 6, 7 are equal and balance the plow in the horizontal plane, excluding its reversal.

Thus, the use of the plow allows you to reduce the height of the ridges of the soil, to achieve uniformity of the degree of crumbling in accordance with agricultural requirements and reduce the energy intensity of the unit.
