Description

The proposed utility model relates to tillage devices, and more specifically, is an addition to a harrow in which spherical disks are used. Spherical disc harrows are widely used. They can work both in plow mode, in harrow mode, and in cultivator mode.

Known working bodies used in harrows with spherical disks.

The disk working body of a tillage implement (see AS USSR No. 1184447, АВВ 33/14, dated 08/18/83) contains a disk on which cutting elements docked to each other by adjacent surfaces are fixed around the circumference of the circle by means of bolt connections.

The disadvantage is that the disk is thick-walled, due to the attachment of the replaceable element. A thick-walled disc is poorly buried in the soil and poorly cuts crop residues, mainly rolling through them.

The crop residues are ejected by the cutting element during rolling, that is, the working stroke of the disc, on the soil surface and remain not crushed, which degrade the quality of tillage and interfere with subsequent technological operations on the field.

Known working body of a tillage implement (see Pat. RF. On PM No. 57073, A01B, 21/00, 03/09/2006) - a prototype containing a rack with a lead on which a bearing assembly with a disc axis and a spherical a disk mounted on the axis of the bearing assembly.

The disadvantage of the working body is that the disc without cuts does not penetrate well and cuts crop residues in the soil. Such a disk simply rolls through crop residues.

The main purpose of such a working body, when used in a harrow, is tillage consisting in the turnover and crumbling of the soil layer.

The technical result of the proposed utility model is to improve the quality of grinding crop residues and soil preparation for processing with spherical disks.

The specified technical result is achieved by the fact that the working body of the grinder is made in the form of a flat disk equipped with perimeter cutting elements in the form of cutouts, teeth or other elements, while the disk, through the bearing, is mounted on an independent stand, for example, self-aligning, directly to which and / or to the bearing assembly, one or more, fixed with

one side of the disk or on both sides, offset relative to each other or symmetrically, a knife that is adjacent to the disk, and with the cutting elements of the disk forms a cutting pair, which ensures during the working stroke of the disk, due to its rotation, cutting of crop residues, like scissors or secateurs.

Disks can also be mounted on a common axis battery.

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

Figure 1 presents a schematic drawing of the working body of the grinder of crop residues.

Figure 2 presents a variety of the working body, as a private form of a grinder of crop residues.

Figure 3 shows the layout of a number of working bodies of the grinder of crop residues on a harrow with spherical disks.

The working body in figure 1 consists of a rack 1, for example, self-aligning. It is possible to use an autonomous non-self-aligning stand of a spherical disc of a harrow. The rack 1 is mounted on the beam 2 located in front of the harrow (see figure 3) frontally. The rack 1 has a stop 3, which abuts the beam 2 through the spring 4 and is fixed with a nut 5. If you use the axis, when the disks of the chopper are battery-mounted, then there will be a disk battery in front of the harrow (see Fig. 3).

A flat disk 7 is attached to the stand 1, through the bearing assembly 6. To the rack 1 and / or to the bearing assembly 6, for example, a saber-shaped knife 8. The knife 8 can be straight or of another shape. The disk 7 is equipped with cutting elements in the form of cutouts 9, teeth 10 or other figures of the cutting elements, shown as examples by positions 11 and 12.

The saber-shaped knife 8 can be located both on one side of the disk 7, and on both sides, when the rack 1 is made in the form of a bicycle fork (see front view). Figure 1 also shows the soil layer 13 and the stem of the crop residue 14.

The working body of figure 2 consists of a rack 1, which is shown as a self-aligning, limiter 3, bearing assembly 6, a flat disk 7, a sickle knife 15, rigidly attached to the bearing assembly 6 and / or to the rack 1.

The disk 7 is equipped with cutouts 9, which serve as the capture of crop residues.

The working body, in addition to the sickle knife 15, may contain a second knife 16, mounted in the plane of the knife 15 and similar. Both knives can be made as one piece.

Figure 3 shows a harrow consisting of a frame 17 with transverse beams 18, on which spherical disks 19 are mounted on stand-alone racks. A beam 2 is installed in front of the harrow (see Fig. 1), on which working bodies are installed, containing flat disks 7 on stand-alone racks. Beam 2 can also be a place for mounting a battery of disks on a common axis.

The working body of figure 1 is a grinder of crop residues as follows.

When the harrow moves in the field, the self-aligning stand 1, having the possibility of rotation in the beam 2, always keeps its direction and the direction of the disk 7, along the direction of movement of the harrow (Fig. 1 is shown by arrow A).

The flat disk 7 does not experience lateral and bending loads, and therefore can be mounted through the bearing assembly 6 on the side of the rack 1, or in the form of a fork of a bicycle wheel (shown in Fig. 1 front view).

The limiter of the rack 3 fixes the rack 1, when moving the rack up and forces the disk 7 to copy the recesses in the soil 13, unclenching and resting the nut 5 in the beam 2.

Due to the absence of bending loads on the disk 7, it can be made of steel sheet 1 ÷ 2 mm thick. This thickness of the disk is well buried in the soil, therefore, the disk may not be sharpened and ensure its performance at a depth of 4 ÷ 5 mm, which is sufficient for the cutouts of the disk 9 to capture crop residues on the soil surface and fix them.

Fixed in the soil layer 13, the stubble stalk 14, the disk 7, rotating will move it to the soil surface, where the stalk 14 will meet the knife 8 and will be cut like a scissors or secateurs.

Cutouts 9, teeth 10 or other designs of cutouts 11 and 12 are used in discs for different types of crop residues (large-stemmed, small-stemmed and others).

When mounting the disk 7, in the rack 1 type of bicycle fork, the knife 8 may be a continuation of the fork on both sides of the disk, which will increase the reliability of cutting the stem 14.

The work of the working body of the grinder of crop residues in figure 2 differs from figure 1 in that it is possible to use other and several knives and, on one or both sides of the disk, placed symmetrically or not, sequentially one after another, which increases reliability chopping crop residues.

In addition, the curvature of the knives 15 and 16, the inverse of the curvature of the knife 8 in figure 1, sickle-shaped, allows you to capture the stem 14 by the type of ticks, guaranteed to hold it and also guaranteed to cut it.

Knife 16 eliminates the appearance of marriage.

Flat discs 7 of the working bodies located on the beam 2, mounted in front of the harrow not only crush the crop residues, but also cut soil strips violating its integrity, as well as violating the integrity of the root system of weeds and the previous culture and this facilitates the work of spherical disks. Even closely spaced self-aligning disks, constantly having free lateral vibration, are not clogged by soil, and therefore they can be placed much closer to each other than spherical disks that have a rigidly fixed installation, which leads to clogging of their soil and

crop residues. Soil pre-prepared with flat discs, with a disturbed structure of the surface soil layer and crushed crop residues, will facilitate and increase the reliability of the spherical discs and, therefore, improve the quality of the soil treatment.

The self-adjusting working bodies do not interfere with the turns of the harrow, always keep the desired direction.

With other racks of the working bodies lateral loads on the disk 7 may occur, and during the turns of the harrow they must be raised above the soil. However, in this case, as in the particular case of the use of chopper disks in the battery version, the direction of movement of the harrow is stabilized, its yaw is excluded. When placing the disks in a battery, the disk knives are fixed to the beam 2. (not shown in Figs. 1 and 3), and the disk battery itself is attached to the beam in parallel and from below.

Racks with flat disks and battery flat disks are different private forms of the same implementation.

The proposed working body ensures the achievement of a technical result.
