Description

The utility model relates to agricultural engineering, namely to the working bodies of soil-cultivating machines.

The cultivator paw is known [Copyright certificate RU patent No. 2714843, IPC class. A01B 35/20, 2020], containing a holder, two wings with blades coated with a wear-resistant layer and a nose part.

The disadvantage of the known cultivator tine design is high traction resistance, poor processing quality, and unstable movement of the unit.

The closest analogue to the claimed one, chosen as a prototype, is the cultivator paw [Copyright certificate RU patent No. 216627, IPC class. A01B 35/26, 2023], containing a holder and paw wings with ends bent down at right angles and with an acute angle of inclination of the cutting edge, an oval-shaped vertical ripper inserted into an open T-shaped groove made in the nose of the paw body along the butt line wings and copying the surface of the paw to the holder with a base in the form of a platform copying the groove.

The disadvantage of the prototype is the high traction resistance due to the enveloping of the holder and the paw stand by weed roots and their dragging. The oval shape and flat sharpening of the ripper do not ensure cutting all the roots of weeds and there is a high probability of them enveloping around the holder and the paw stand.

The technical result of the utility model is to reduce the enveloping of the holder and paw stand by weeds while reducing traction resistance.

The technical result is achieved due to the fact that the upper part of the ripper has a serrated sharpening, and spring steel rods are welded to its side planes, bent back around the holder without contacting it and fanning out so that the distance between the rear ends of the rods is twice as large distances between them at fastening points.

This set of essential features ensures that the inventive cultivator paw has new properties that differ from the prototype.

Thus, the declared features of the utility model meet the “novelty” criterion.

In fig. 1 shows a diagram of the cultivator's paw in axonometry;

in fig. 2 - view of the upper part of the ripper with serrated sharpening, rotated.

A cultivator paw containing a holder 8 (Fig. 1) and wings 5, 9 paws with ends 6 bent down at right angles and with an acute angle of inclination of the cutting edge 4, a vertical ripper 1 oval in shape, inserted into an open T-shaped groove made in the nose part of the paw body along the joint line of the wings and copying the surface of the paw to the holder with a base 2 in the form of a platform copying the groove, and the upper part 3 of the ripper has a serrated sharpening 10 (Fig. 2), and spring steel rods 7 are welded to its side planes, curved back, bending around the holder without contacting it and fanning out so that the distance between the rear ends of the rods is twice the distance between them at the attachment points.

The cultivator paw works as follows.

Before starting operation of the device, set the crumbling angle of the wings 5, 9 paws to zero. Ripper 1 with base 2 is inserted into the open T-shaped groove.

When the device moves, wings 5, 9 paws cut the soil layer. The ends of the 6 wings of the paws, bent downwards at right angles, cut cracks in the soil to a depth half the depth of tillage.

At the same time, the ripper 1 with its upper part 3 cuts the roots of weeds, and the rods 7 move the cut roots away from the holder and the stand, preventing them from enveloping.

The presence of serrated sharpening 10 on the upper part 3 of the ripper increases the efficiency of cutting the roots of weeds and, together with the rods 7, ensures that the roots do not envelop the holder and the paw stand. At the same time, due to the absence of root dragging, the traction resistance of the paw is reduced.

Thus, the declared technical result is ensured.
