Abstract

The utility model relates to agricultural engineering, in particular to tillage implements for basic soil cultivation. The technical result of the utility model is to increase the function of protecting the stand from enveloping weeds and plant residues. The technical result is achieved due to the fact that the fairing is welded to the stand with its lower part moving in the soil, and its upper above-ground part is spatially smoothly bent sideways and backward relative to the direction of movement. The working body of a subsoiler, including a supporting post with a flat triangular toe in side view, a round fairing with a triangular end welded to the front plane of the post, a flat V-shaped chisel mounted with interference on the toe of the post, consisting of upper and lower flat elements welded between themselves with an opening angle equal to the angle at the top of the triangular toe of the rack, the tension of the bit is ensured by a bolt passing through the bushing fixed in the lower part of the rack and screwed into the threaded hole of the lower flat element of the bit, while there is a gap between the bushing and the lower flat element of the bit 3-5 mm, and the upper flat element of the bit has a triangular cutout into which the triangular end of the fairing fits, and the fairing is welded to the stand with its lower part moving in the soil, and its upper above-ground part is spatially smoothly bent sideways and backward relative to the direction of movement.

Description

The utility model relates to agricultural engineering, in particular to tillage implements for basic soil cultivation.

The working body of a tillage implement is known [Copyright certificate RU patent No. 176153, IPC class. A01B 35/20, A01B 15/02, 2018], including a supporting stand, removable scoring knives installed in its lower part and an overhead chisel.

The disadvantage of the known working body is that the bit is made in the form of a flat or arcuate plate and is fixed to the toe of the supporting post using at least two bolted connections, while the front part of the flat bit with the cutting edge is cantilevered relative to the toe of the post, which reduces the strength of the bit when its interaction with the soil due to bending, and the limited thickness of the flat bit reduces bit wear.

The closest analogue to the claimed one, adopted as a prototype, is the working body of the subsoiler [Copyright certificate RU patent No. 218938, IPC class. А01В 13/14, 2023], including a load-bearing post with a flat triangular toe in side view, a round fairing with a triangular end welded to the front plane of the post, a flat V-shaped bit installed with interference on the toe of the post, consisting of an upper and lower flat elements welded together with an opening angle equal to the angle at the top of the triangular toe of the post, the bit tension is ensured by a bolt passing through the bushing fixed in the lower part of the post and screwed into the threaded hole of the lower flat element of the bit, between the bushing and the lower flat element There is a gap of 3-5 mm between the bits, and the upper flat element of the bit has a triangular cutout into which the triangular end of the fairing fits.

The disadvantage of the prototype is the high probability of enveloping the stand with weeds and plant debris.

The technical result of the utility model is to increase the function of protecting the stand from enveloping weeds and plant residues.

The technical result is achieved due to the fact that the fairing is welded to the stand with its lower part moving in the soil, and its upper above-ground part is spatially smoothly bent sideways and backward relative to the direction of movement.

This set of essential features ensures that the inventive working body of the subsoiler acquires 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 subsoiler working body assembly, right side view;

in fig. 2 - the same, left view;

in fig. 3 - front view of the working body in interaction with soil and weeds.

The working body of a subsoiler, including a supporting post 1 with a flat triangular toe 9 in side view, a round fairing 3 with a triangular end 8, welded to the front plane of the post 1, a flat V-shaped chisel mounted with interference on the toe of the post, consisting of an upper 4 and the lower 5 flat elements, welded together with an opening angle equal to the angle at the top of the triangular toe 9 of the post, the tension of the bit is ensured by a bolt 7 passing through the sleeve 6, fixed in the lower part of the post 1, and screwed into the threaded hole of the lower flat element of the bit, in this case, between the sleeve 6 and the lower flat element 5 of the bit there is a gap of 3-5 mm, and the upper flat element 4 of the bit has a triangular cutout into which the triangular end 8 of the fairing fits, and the fairing 3 is welded to the stand with its lower part moving in the soil, and its upper supra-ground part 10 is spatially smoothly bent sideways and backward relative to the direction of movement.

The working parts of the subsoiler are attached to its frame with a bolted connection using holes 2.

When the declared working body of the subsoiler is operating, the part of the stand 1 moving in the soil with the fairing 3, the upper 4 and lower 5 flat elements of the bit interact with the treated soil layer at the required depth. In this case, the roots of weeds are cut and the soil crumbles due to the propagation of cracks 12 in it (Fig. 3). Trimmed weeds 11 and plant residues located on the soil surface slide along the fairing 3 up and away from the stand, slide off the fairing and fall to the soil surface. Thus, the stand is protected from enveloping weeds and plant debris.
