Description

Paw cultivator ° ° °

The utility model relates to agricultural engineering, namely, to the working bodies of anti-erosion cultivators.

Known cultivator paws for working at a depth of 4 ... 6 cm with a formation angle of 13 ... L6 ° and a crumbling angle (3 15 ... 30 ° with a working width of 145 ... 290 mm.

The disadvantage of these paws is:

-the ability to work only at a certain (shallow) depth;

-high percentage of damaged stubble due to the large number of racks;

- low service life.

Paws for working at a depth of 8 ... 16 cm are known; they have a cutting angle of 28 ... .32 °, a working width of 220 ... .330 mm. A disadvantage of the known paws is:

-the ability to work only at a depth of more than 8 cm, at shallower depths, the bottom of the furrow is exposed;

- the formation of a large number of furrows;

- low service life

The problem the proposed utility model is aimed at solving:

-creation of a cultivating paw used to work both at a shallow depth of 6 ... 8 cm and at a depth of 16 cm;

-maximum stubble conservation;

-full cutting of weeds;

-increase the resource.

The mentioned task is achieved by the fact that the angle of elevation of the soil layer to the horizon is applied at 4 ... 10 °, the crushing angle is p ... 8 ... 12 °, the angles provide high-quality loosening and complete cutting of weeds at different depths of processing.

The width of the gripping legs 410 ... 420 mm provides the necessary rigidity and, as a result, the formation of a flat bottom of the furrow. The maximum conservation of stubble is achieved by reducing the number of racks and, accordingly, the number of breakup grooves.

To create conditions for self-sharpening, the blade of the paw is subjected to induction surfacing with the PG-US-25S hard alloy. This makes it two-layer and provides the blade with self-sharpening during operation due to faster wear of the base material and the appearance of a deposited layer from under it with a thickness of 0.4 ... 0.8 mm. In this case, the cutting edge does not lose

sharpness and provides good cutting of weed vegetation. Thanks to the self-sharpening effect, the paw resource is increased by 1.5 ... 2 times and the quality of loosening is improved.

Figure 1 shows a cultivating leg side view; in FIG. 2 - view in plan; in FIG. 3 - view A, where the angle of formation rise is 1; capture width - 2; crumbling angle - 3; carbide surfacing - 4.

As a result, a cultivating paw with the parameters proposed in the utility model and deposited with a hard alloy provides an increase in resource up to 45 ... 60 hectares depending on the type of soil, high-quality cultivation at a depth of 6 ... 16 cm, maximum conservation of stubble and complete cutting of weeds .
