RU222026U1 - CHISEL SOIL TILLAGE UNIT - Google Patents

Abstract

The utility model relates to agricultural engineering, in particular to tillage units for basic non-moldboard tillage. The technical result of the utility model is to improve the quality of work. The technical result is achieved due to the fact that the L-shaped rippers are hingedly attached to the stands of the chisel paws and can be adjusted both in height and at different angles of inclination to the horizon by aligning and fixing with a finger the holes on the L-shaped ripper and the corresponding holes on the stand chisel paw. A chisel soil-cultivating unit includes a frame with support wheels, an attachment, chisel paws mounted on the frame, the racks of which are placed in rows, the front edge of the racks is sharpened on both sides, the racks have through holes in which L-shaped rippers are installed on both sides of the rack, with a cutting edge directed in the direction of movement of the unit, a roller attachment installed behind the chisel paws with loosening and leveling rollers mounted on an H-shaped frame, pivotally connected and spring-loaded relative to the frame of the unit, and the L-shaped rippers are hingedly attached to the chisel paw stands and can be rearranged as in height, and at different angles of inclination to the horizon by aligning and fixing with a finger the holes on the L-shaped ripper and the corresponding holes on the chisel paw stand.

Description

The utility model relates to agricultural engineering, in particular to tillage units for basic non-moldboard tillage.

A universal combined tillage unit is known [Copyright certificate RU patent No. 2452158, IPC class. А01В 49/02, 2012], including a frame with support wheels, a mounted or towed device, flat-cutting or chisel paws mounted on it in series, mounted on racks and placed in several rows, after which roller batteries are hinged in one or two rows - a clod breaker with tooth discs, behind which sections of a rod rotor or a leveler beam section with teeth bent in two planes are installed on the crossbeams, while the disc batteries of the clod crusher roller are installed at an angle of attack in pairs, symmetrically relative to the axis of the unit, the disc teeth are made with one-sided sharpening.

However, the known unit has a drawback, which includes the unsatisfactory quality of tillage.

The closest analogue to the claimed one, chosen as a prototype, is a chisel tillage unit [Copyright certificate RU patent No. 216938, IPC class. А01В 49/02, А01В 13/14, 2023], including a frame with support wheels, a hinged device, chisel paws mounted on the frame, the racks of which are placed in rows, the front edge of the racks is sharpened on both sides, the racks have through holes in which on both sides On the sides of the rack there are L-shaped rippers with a cutting edge directed in the direction of movement of the unit, a roller attachment installed behind the chisel paws with loosening and leveling rollers installed on an H-shaped frame, hinged and spring-loaded relative to the frame of the unit.

The disadvantage of the prototype is the insufficiently high quality of work at different depths and on different types of soils with different humidity.

The technical result of the utility model is to improve the quality of work.

The technical result is achieved due to the fact that the L-shaped rippers are hingedly attached to the stands of the chisel paws and can be adjusted both in height and at different angles of inclination to the horizon by aligning and fixing with a finger the holes on the L-shaped ripper and the corresponding holes on the stand chisel paw.

This set of essential features ensures that the proposed chisel soil-cultivating unit has new properties that are different from the prototype.

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

In fig. 1 shows a diagram of a chisel soil-cultivating unit, side view; Fig. 2 - the same, top view, in Fig. 3 - extension element A in Fig. 1.

Chisel tillage unit, including frame 7, Fig. 1, with support wheels 5, attachment 6, chisel paws 1 mounted on frame 7, racks 2 of which are placed in rows, the front edge of the racks is sharpened on both sides, through holes 8 are made on the racks, in which L-shaped rippers are installed on both sides of the rack 4 with a cutting edge directed towards the movement of the unit, installed behind the chisel paws; 1 roller attachment with ripper 12 and leveling 10 type rollers installed on an H-shaped frame 11, hinged and spring-loaded relative to the frame of the unit, with L-shaped rippers 4 attached to the chisel racks The paws are hinged and can be adjusted both in height and at different angles of inclination to the horizon by aligning and fixing with fingers 3 holes on the L-shaped ripper 4 and the corresponding holes on the stand 2 of the chisel paw 1.

The chisel tillage unit works as follows.

The unit is first coupled to the tractor using a hitch 6. The racks 2 are placed together with the chisel paws 1 in rows on the frame 7, Fig. 2. By rotating the handles of the screw adjustment mechanisms, the required height of the support wheels 5 is set relative to the toes of the chisel paws 1, i.e. depth of soil cultivation, which is sufficient to destroy with chisel paws 1 plow sole formed after tillage of the soil with moldboard plows. On both sides of the posts 2, depending on the required depth of loosening and the condition of the soil, by aligning the holes 8 on the posts 2, FIG. 3, and on the rippers 4 and fixing them with fingers 3, the required height and angle of inclination of the L-shaped rippers 4 to the horizon are set, FIG. 1, positions B, B, C. By tightening or unscrewing the nuts located on the rods of the roller attachment, the necessary compression or stretching of the springs 9 is achieved, thereby regulating the pressure of the rollers 10 and 12 on the soil. Thanks to the hinge 13 for attaching the H-shaped frame 11 to the frame 7 of the unit, the pressure on the soil is distributed evenly between the rollers 10 and 12 and their ability to copy uneven terrain increases.

When the chisel tillage unit moves, the chisel tines 1 and stands 2 loosen the soil and destroy the plow sole. The cutting edges of L-shaped rippers loosen the top layer of soil to a depth of 6-8 cm and trim weeds located in the top (fertile) layer of soil. For high-quality loosening of the top layer of cohesive and moist soils, the angle of inclination of the L-shaped rippers 4 to the horizon is increased, and for processing poorly cohesive soils, the angle is reduced to reduce energy intensity while maintaining the required quality. The optimal angle of inclination of the L-shaped rippers 4 to the horizon for specific conditions is determined experimentally during the first pass of the unit in the paddock.
