Description

The invention relates to agricultural machinery, namely, to devices for processing compacted soil in the tracks of tractors.

A tractor follower is known, including side sections mounted on a transverse beam, each of which contains stippers arranged in a checkerboard pattern, in front of which knives are mounted staggered relative to the latter [Tractor follower. Patent RU No. 2142681. Publ. 12/20/1999, Bull. No. 35].

A disadvantage of the known implements is the low quality of processing compacted soil in the tracks of tractors due to the removal of large lumps of soil from cut tapes by vertical knives and subsequent unloading by cultivators, as well as the not optimal density of the treated soil.

Known tractor baking powder, including lateral sections mounted on a transverse beam, each of which contains rippers with legs arranged in two rows parallel to the transverse beam in a checkerboard pattern relative to each other, and knives made in the form of racks of rippers, behind which there is a reactive tooth disk battery followed by a tooth disc drive battery. In this case, the forward-facing teeth of the disks of the jet battery are located above the legs of the cultivators of the rear row opposite the midpoints of the intervals between adjacent knives of the front and rear rows, and the teeth of the disks of the drive battery are located between the teeth of the disks of the jet battery [Tractor dehumidifier. Patent RU No. 2282958. Publ. 09/10/2006, Bull. No. 25].

A disadvantage of the known tool is the low quality of processing compacted soil in the tracks of tractors due to the removal of large clods of soil from the cut tapes by vertical front knives upwards and its subsequent unloading of tooth discs with cultivators and reactive batteries, as well as the not optimal density of the treated soil.

The purpose of the invention is to improve the quality of processing compacted soil in the tracks of tractors.

This goal is achieved by the fact that the racks of the rippers perform tilted relative to the vertical along the movement of the unit at an angle of 20 ° ... 30 °. At the same time, on the rear edge of the rear row of cultivators, the legs are set horizontally in two tiers, with the ends of the legs located on one vertical line that coincides with the axis of symmetry of the tooth disc drive battery installed above. Behind the battery of tooth disks, half-frames rigidly connected with the transverse beam, with the possibility of changing the installation depth, are equipped with plane cutters made in the form of arrow-shaped flat blades, behind each of which a bar-blade roller with a front bar-concave surface of the blades is installed.

Figure 1 shows a General view of the tractor tractor ripper, figure 2 is the same, a top view, figure 3 is a rear row cultivator.

The tractor’s tractor opener comprises a transverse beam 2 mounted on the tractor attachment 1, on which side working sections 3 are mounted, each of which includes cultivators with knife racks arranged in two rows parallel to the transverse beam 2. The rear row of cultivators 4 are equipped with tabs 5 and are mounted in a checkerboard order relative to rippers 6 of the front row. A rear battery of tooth disks 7 with an arrangement of teeth of the disks opposite the midpoints of the intervals between adjacent rippers 6 and 4 of the front and rear rows, respectively, is installed behind the rear row of cultivators 4. Knife racks of rippers 4 and 6 are made inclined relative to the vertical along the unit at an angle of 20 ° ... 30 °. On the rear edge of the rippers 4 of the rear row of the legs 5 are mounted horizontally in two tiers, with the ends of the legs 5 on the same vertical line, which coincides with the axis of symmetry of the tooth disks 7 installed above the drive battery. The tooth disks 7 are mounted on half frames 8, which are rigidly connected with the 2, flat-cutters 9 are installed. Flat-cutters 9 are made in the form of arrow-shaped flat blades, and to provide the possibility of changing the depth of their installation, they are placed under the half-frames 8 and connected with them by screw mechanisms 10. Behind each square Oscoretic 9 installed bar-blade roller 11 with a front bar concave surface of the blades.

The tractor baking powder works as follows.

Pre-plane cutters 9 using screw mechanisms 10 are set to the desired processing depth, moving them down or up relative to the half frames 8, rigidly connected with the transverse beam 2. Then, the track disintegrant using the tractor attachment 1 is put into working position. When the unit moves, the knife posts of the cultivators 6 and 4 of the front and rear rows, respectively, are deepened into the soil to the depth of processing. Inclined relative to the vertical along the unit at an angle of 20 ° ... 30 °, the knife racks of cultivators 4 and 6 cut the soil compacted along the trace of the factor in a vertical plane without moving it up. Installed horizontally in two tiers on the trailing edge of the cultivators 4 of the rear row of the foot 5, the ends of which are located on the same vertical line, which coincides with the axis of symmetry of the tooth disks 7 installed above the drive battery, loosen the soil in layers and form soil layers synchronously along the tractor. The drive battery of the tooth disks 7 installed above simultaneously loosens these layers and discards the soil to a two-section bar-blade roller 11, which loosens the soil lumps with the rods of the blades and evenly distributes them along the field surface. Flat cutters 9 loosen the soil with the upper part of the arrow-shaped flat blades, with their lower part form the bottom of the cultivated soil volume, and bar-blade rollers 11 create a predetermined density of addition between the upper part of the arrow-shaped flat blades of the plane cutters 9 and the soil surface.

The quality of processing compacted soil in the tractor tracks is improved due to the implementation of the knife racks of cultivators tilted relative to the vertical along the unit at an angle of 20 ° ... 30 ° and the installation of the rear row of legs on the trailing edge of the cultivators horizontally in two tiers, with the ends of the legs on the same vertical line coinciding with the axis of symmetry of the tooth disk drive battery mounted above. This contributes to high-quality cutting with sliding soil in a vertical plane without unloading and carrying it up. At the same time, the paws provide layer-by-layer cultivation of undamaged soil tapes of a given width, as well as synchronous formation of soil layers along the direction of movement of the tractor for further effective cultivation of the tooth disks installed above the drive battery.

The quality of processing compacted soil in the traces of tractors also improves due to the installation of tooth disks of rod-blade rollers behind the drive battery, which loosen the soil lumps with the bars of the blades to the size of the inter-bar distance by counter-acting on the soil layer thrown from the drive battery of the tooth disks and evenly distribute it over the field surface frontal bar concave surface of the blades. The plane cutters installed in front of and below the rollers with the upper part of the arrow-shaped flat blades additionally loosen the soil, and with their lower form the bottom of the cultivated soil volume. The screw mechanism connecting the half-frames with plane-cutters, changing the depth of installation of swept flat blades, sets the required depth of tillage, which ensures that the bar-and-blade rollers in it create a predetermined optimal soil folding density.
