RU220828U1 - MULTIFUNCTIONAL SOIL TILLAGE DEVICE - Google Patents

Abstract

The utility model relates to the field of agriculture, in particular to soil-cultivating machines. The technical result of the utility model is a reduction in traction resistance while reducing the winding of weed roots on the stand. The technical result is achieved due to the fact that the cutting part of the ripper has a blade with an opening angle of 40° and serrated sharpening on it. A multifunctional soil-cultivating device containing a stand, a holder made in the form of a block, the front horizontal half of which is bent at an angle of 110° to the rear half attached to the stand of the unit, wings, a ripper and a slotter, made of an oval shape with different depths of soil cultivation, and the cutting part The ripper has a blade with an opening angle of 40° and serrated sharpening on it.

Description

The utility model relates to the field of agriculture, in particular to soil-cultivating machines.

A device for tillage is known [Copyright certificate RU patent No. 2730659, IPC class. A01B 49/02, 2020], containing a holder, ripper, crevice and cultivator feet.

The disadvantage of the known device is that it is impossible for them to carry out various tillage operations separately, for example, slitting without loosening the soil or vice versa, or cultivation without them, as well as cutting weeds with one wing, with right- or left-hand action. Carrying out different operations separately increases operating costs.

The closest analogue to the claimed one, chosen as a prototype, is a multifunctional tillage device [Copyright certificate RU patent No. 216439, IPC class. A01B 49/02, 2023], containing a stand, a holder made in the form of a block, the front horizontal half of which is bent at an angle of 110° to the rear half attached to the stand of the unit, wings, a ripper and a slotter made of an oval shape with different depths of soil cultivation.

The disadvantage of the prototype is that the cutting part of the ripper does not have a special sharpening for effectively cutting the roots of weeds. As a result, uncut roots move over the ripper and envelop the stand, increasing traction resistance.

The technical result of the utility model is a reduction in traction resistance while reducing the winding of weed roots on the stand.

The technical result is achieved due to the fact that the cutting part of the ripper has a blade with an opening angle of 40° and serrated sharpening on it.

This set of essential features ensures that the inventive multifunctional tillage device 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 a multifunctional soil-cultivating device, a side axonometric view, Fig. 2 - the same, top view, in Fig. 3 - extension element in Fig. 2.

A multifunctional tillage device containing a stand 4, a holder 3 made in the form of a block, the front horizontal half of which is bent at an angle of 110° to the rear half attached to the stand of the unit, wings 1, a ripper 2 and a slotter 5 made of an oval shape with different depths of tillage. , moreover, the cutting part of the ripper has a blade 7 with an opening angle of 40° and a serrated sharpening 8 on it.

The multifunctional tillage device works as follows.

Before starting work, holder 3 with its rear bent part is secured to the unit stand with a threaded connection, not shown. The working parts: ripper 2, slotter 5 and wings 1 are inserted into grooves 9 through the slots of the front holder 3.

When the unit moves, the wings 1, installed on the sides of the holder 3, trim the weeds. Ripper 2, installed above holder 3, loosens the soil. Crevice 5 creates a gap that helps regulate the water-air balance of the soil.

Ripper 2 with a wedge-shaped front part 6, its blade 7 with an optimal opening angle of 40° and serrated sharpening 8 on it effectively cuts plant roots and prevents them from wrapping around the stand. It is known that a blade with a serrated sharpening cuts materials with a fibrous structure with relative sliding with less force than a blade with a smooth sharpening, and according to [Klenin N.I., Sakun V.A. Agricultural and reclamation machines - M.: Kolos, 1994. - P. 40], the blade angle should not exceed 45°.
