Abstract

FIELD: agriculture.

SUBSTANCE: tillage tool consists of a frame (1) with a suspension mechanism (2), a battery (3) with needle-like working bodies (6) equipped with a drive (4) for rotation. In the battery (3), needles (6) of equal length are placed radially on the shaft in groups in three planes, sequentially rotated around the shaft axis by 60° relative to each other. The needles (6) of each group are offset relative to the needles (6) of the subsequent group by a step along the shaft axis.

EFFECT: quality of tillage is improved, the tool is not clogged with plant residues and soil during operation.

Description

The invention relates to agricultural engineering, in particular to tillage tools.

Known tillage tool [1] containing batteries of needle discs for combing out weeds, crushing clods and leveling the soil.

The disadvantage of the known device is that during the operation of the tool, the batteries of plant residues and soil are clogged on the needle disks on the needle discs, which leads to disruption of the technological process of soil cultivation. In addition, the passive action of the working body - needle discs on the soil is ineffective.

The closest analogue of the proposed invention is a tillage tool [2], which includes a frame, batteries of needle discs equipped with a drive for rotation, as well as a device for cleaning needle discs from stuck soil and vegetation residues. This somewhat reduces the clogging of the implement during operation. However, it should be noted that in it the needles in the disks make a rotational movement in the common planes of the disks, which makes it difficult for them to self-clean during operation. This increases the likelihood of plant debris and soil clogging the spaces between the needles in the needle discs. In addition, there is a high likelihood of clogging of soil lumps between the needle discs. Therefore, the needle discs are installed on the shaft at distances of large lump sizes. However, soil clods can remain untreated in the field, passing between the needle discs. This degrades the overall quality of soil cultivation.

The objective of the proposed invention is to completely eliminate the clogging of the tool by soil and vegetation with residues, as well as to improve the quality of soil cultivation.

The technical result is the elimination of clogging of the tool with soil and plant residues, as well as an increase in the quality of soil cultivation.

This is achieved by the fact that in a tillage implement containing a frame with a linkage mechanism and a battery with needle working bodies equipped with a drive for rotation, needles of equal length in the battery are placed on the shaft radially in groups in three planes sequentially rotated around the shaft axis by 60 ° relative to each other. each other, and the needles of each group are displaced relative to the needles of the next group by a step along the axis of the shaft.

The specified order of placing the needles on the shaft allows each of them to provide its own planes of rotation, located at minimum distances along the shaft, to have the needles maximum phase shift equal to 60 ° relative to each other in the direction of rotation. In this case, lumps of soil cannot wedge between the needles, since their interaction occurs simultaneously with only one needle, since the adjacent needle enters into operation sequentially with a shift of 60 °. At the same time, plant residues that are hanging simultaneously on only one needle (the neighboring needle is not yet involved in the work) come off it in the process of interacting with the soil, without having a stable location with one point of contact with the working body.

In this case, the soil is treated with high quality, since the needles come into operation sequentially in different working planes of rotation, which are at a minimum step along the axis of the battery.

FIG. 1 shows a general view of a tillage tool, FIG. 2 is a cross-sectional view of a battery with needle-like working bodies.

The tillage tool contains a frame 1 (Fig. 1) with a linkage mechanism 2, a needle battery 3 with a drive 4 for rotation. Needle battery 3, in turn, consists of shaft 5 and needles 6. Needles 6 are placed on shaft 5 radially to its axis in three groups in the corresponding planes II, II-II and III-III, sequentially rotated around the shaft axis by 60 ° relative to each other (see Fig. 2), and the needles of one group are displaced relative to the needles of the next group by a step t along the axis of the shaft (see Fig. 1).

The tillage implement works as follows. Before starting work, the needle battery is brought into rotation by turning its drive into operation. During the rotation of the battery, its needles come into interaction with the soil in groups successively after 60 ° of rotation. They comb weeds from the soil, break up lumps of soil, giving it a fine lumpy structure of a certain density. Due to the adopted scheme for placing the needles in the battery, the distance between the needles in the group is equal to three steps t of their placement in their entirety on the shaft, and each adjacent needle interacts with the soil, delaying by 60 ° of rotation of the shaft. This avoids the accumulation of soil particles and plant debris in the spaces between the needles, i.e. eliminates the possibility of clogging of the working body.

The use of the proposed tillage tool allows to improve the quality of soil cultivation, to exclude clogging of the tool with plant residues and soil during operation.
