Abstract

A disk tillage implement containing a frame with transverse bars fixed to it in several rows, on which racks are autonomously mounted, at the ends of which spherical disks are mounted and rotatable attached to the frame, characterized in that the spherical disks on autonomous racks are mounted on the implement front rows, and the axis of symmetry of the gun divides each row into the left and right parts with the same number of disks mounted at an angle to the direction of motion mirror in the opposite sides, while the disks of each part of the next row are turned in the direction opposite to the analogous part of the previous row, and the disks with the total concave sides of the soil equal to the interdisc space of the disks of the same row located most close to the axis of symmetry of the implement are installed on the symmetry axis of the implement .

Description

The proposed utility model relates to disk tillage implements, for example, to cultivators and harrows, including spherical disks on autonomous racks.

Known disk tillage implement (see US Pat. RF No. 2291605, АВВ 21/08, dated October 17, 2005), containing a frame with transverse bars fixed to it in several rows, on which racks with axes at the ends are independently mounted and installed on the axles, with the possibility of rotation, spherical disks. In this case, the disks have an angle of attack, are inclined to a vertical plane and are installed frontally along the width of the capture in rows. The disks in the rows are directed by the convexity or concavity to the longitudinal axis of symmetry of the implement in such a way that the number of disks in each row of one direction on one side of the axis of symmetry is equal to the number of disks of the opposite direction on its other side, while between the disks of the first row of the implement along its longitudinal line axis of symmetry, a plane-cutting paw with a working width equal to the interdisk space of the middle disks of the last row is installed. This arrangement of disks increases the directional stability of the guns.

The disadvantage of such a disk tillage implement is that the disks of each side with respect to the axis of symmetry discard the soil in one direction, which leads to the formation of a groove in the center of the implement along the axis of symmetry and to the spread of soil on the untreated surface at the edges. This reduces the quality of tillage.

Known disk tillage implement (see US Pat. RF on subway number 78394, АВВ 21/08, dated 02/27/2008) is a prototype containing a frame with beams on which autonomous working bodies with spherical disks, a tow hitch and a roller are installed - soil leveler. The tool is equipped with supporting copy wheels with the possibility of their movement relative to the frame up and down. The disks, relative to the axis of symmetry of the guns, are mounted mirrored and directed in opposite directions, which increases the directional stability of the guns. A working body is installed along the axis of symmetry of the gun, for example, a spherical disk on a rack.

The disadvantage of this disk tillage tool is that the disks on each side discard the soil relative to the axis of symmetry in different directions, which leads to the formation of a groove along the axis of symmetry of the implement behind the last spherical disk on an autonomous stand and the formation of ridges on the untreated surface on the sides of the implement. This reduces the quality of tillage.

The technical result of the proposed utility model is to improve the quality of tillage.

The specified technical result is achieved by the fact that the spherical disks on autonomous racks are mounted on the implement in front rows, and the axis of symmetry of the implement divides each row into the left and right parts with the same number of disks mounted at an angle to the direction of movement mirror in opposite directions, while the disks of each parts of the next row are turned in the direction opposite to the analogous part of the previous row, and disks with a soil capture width are set on the counter-concave sides of the implement’s axis of symmetry disks of the same row closest to the symmetry axis of the guns

The essence of the utility model will be described in more detail below.

Figure 1 presents a schematic drawing of a disk tillage implement (harrow) with the proposed layout of spherical disks on this harrow.

The harrow consists of a frame 1, with transverse bars 2 fixed on it in several rows, on which autonomous working bodies are mounted, consisting of a rack 3, with a rotating spherical disk 4. A towing device 5 is attached to the frame 1. The guns are mounted counter-concave along the symmetry axis sides of the disk 6 and disk 7 with a width of soil capture S - equal to the inter-disk gap of the tools closest to the axis of symmetry, disks of the same row 8 and 9.

Disk tillage implement works as follows.

With a hitch 5, the harrow is attached to the tractor (not shown in FIG. 1) and moves across the field in the operating mode with the working bodies lowered into the soil. By its mass, the harrow deepens 4 spherical disks into the soil. Racks 3 discs 4 give an angle to the direction of movement (angle of attack). The angle of attack determines the width of the furrow and the direction of throwing the soil toward the inner sphere of the disk 4. In order not to turn the harrow to the side, each row of discs is divided relative to the axis of symmetry of the harrow into two equal and symmetrical parts with the same angle of attack and the same interdisk distance. The layout of the drives of the first row will determine the placement of the drives of the 2nd and subsequent rows. The symmetrical left and right parts of the discs in a row wrap each soil in its own direction. The next row of discs makes the soil turn in the opposite direction and so on. The result is a uniform distribution of soil along the width of the implement. The directional stability of the harrow remains good, since there are no unfolding moments of forces. The untreated strip of soil along the axis of symmetry of the implement is processed by disks 6 and 7, which are installed with a compensated unfolding moment of forces.

All of the above ensures the achievement of a technical result.
