Abstract

FIELD: agriculture.

SUBSTANCE: device comprises disk slot cutters with drive from power take-off shaft. Disks of slot cutters are arranged as carved and toothed. One cutting edge of each tooth in slot cutter disk is arranged as straight, and another edge - along parabola set by formula y²=2px. At the edge arranged in the form of parabola there are working elements fixed in the form of knives with cutting edge that consists of two parts. One part of cutting edge of knives is arranged as straight, and the other one is arranged along parabola y²=2px at the whole length of tooth. Straight cutting edge of knife is installed at the angle α=65…70° and is arranged with length of 60 mm. Device is equipped with jacket arranged with box-like shape, having width that is more than width of cut slot and length more than disks diametre.

EFFECT: such design will make it possible to reduce traction resistance and to improve quality of rotary para ploughing.

Description

The invention relates to agricultural machinery and is intended for cutting cracks.

A device for clearing soils in meadows and pastures is known, including two scherrez knives deepened to 40 cm, and a device for forming waterproof rollers above the slit [1].

The disadvantage of this device is the high traction resistance due to the need for passive crevice, the low quality of the soil.

A device for soil cleavage, containing passive slotting machines with rotary cultivators [2].

The disadvantages of this device include high traction resistance due to the need for passive slotting machines.

Known rotary cultivator podgumusnogo soil layer containing two disk cherezeres and located between them rotary cultivator [3].

The disadvantages of this device include the low quality of the soil treatment caused by the insufficient degree of crumbling and loosening of the soil. And also the main disadvantage of these sclerosis is that they form open slots that require alignment.

The aim of the invention is to reduce traction resistance and improve the quality of rotational soil sowing.

This is achieved by the fact that the device for cutting slots contains rotary disk crevices, consisting of teeth, one cutting edge of which is made in a straight line, and the other in a parabola, given by the formula at ² = 2рр. On the edge, made in the form of a parabola, there are fixed working elements in the form of knives with a cutting edge, consisting of two parts: one, which is set at the periphery at an angle α = 65 ... 70 °, a straight line 60 mm long, the other is made along a parabola at ² = 2 px along the entire length of the tooth to the curved edge of the tooth.

The invention is illustrated by the attached schemes, where:

figure 1 is a diagram of the sowing of the aisles of perennial plantations when tinned, where a is the distance between the cracks, may vary depending on the planting scheme of fruit trees, c is the protection zone, h is the processing depth;

figure 2 - diagram of a device for snapping row spacing of perennial plantations when tinned;

figure 3 is a diagram of disk cherezere, side view;

figure 4 is the same, front view with a casing.

A device for snapping row spacing of perennial plantations (Fig. 2) consists of a frame 1 on which the working sections 2 are mounted, a bevel gear 3 and the support wheels 11. A block with interchangeable gears 5 is mounted on the working section to change the speed of the working body. It also has a shaft with a working body - disk slitherese 7 (Fig. 3), consisting of teeth 8, one cutting edge 12 of which is made in a straight line, and the other edge 13 - in a parabola given by the formula ² = ² px. On the edge, made in the form of a parabola, working elements are fixed in the form of knives 9 with a cutting edge consisting of two parts: one 14, which is installed at an angle α = 65 ... 70 on the periphery, a straight line 60 mm long, the other 15 (FIG. 4) performed on a parabola y ² = 2px along the entire length of the tooth to the curved edge of the tooth. The gearbox is connected to the gear block by cardan transmission 4 (Fig.2). The drive gear of the disk shearer is connected to the gear unit by a chain gear 6. For the distribution of soil in the slot and above it, a guide casing 10 is used, which is box-shaped, wider than the width of the cut slit and longer than the diameter of the disk shearer, and is set at a height that does not allow changing soil structure. To adjust the depth of tillage, support wheels 11 are used.

The rotation of disk slippers is reverse - from bottom to top and is carried out from the tractor power take-off shaft (not shown). This allows for a more stable process of cutting gaps, because eliminates the deepening of the working bodies during operation and clogging them with plant residues.

The proposed device operates as follows. When the unit moves in the row-spacing of fruit stands, the disk slitherese 7 cuts the cracks (Fig. 1), and the soil chips are cut off by the straight cutting edge 12 of the tooth 8 and the cutting edge of the straight part 14 of the knife 9. Next, moving along the second part 15 of the knife, made in the form of a parabola with a given formula y ² = 2px, the chips are crushed to a given structure. Moreover, the degree of grinding can be changed depending on the physico-mechanical properties of the soil, changing the parameter of the parabola - p. Then, the crushed soil is discarded to the guide casing 10, which is installed in such a way that the soil is laid in and above the gap.
