Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to machines for cutting furrows or ridges. The aim of the invention is to increase productivity. The unit consists of a tractor 1 With 2 right and left 3 pairs of wheels. A frame 4 is connected to the tractor 1, on which the working bodies (RO) 7 are fastened. The ROs are mounted in sections. The central 5 and each of the lateral 6 sections are located at a distance equal to twice the distance between the PO in the section. On frame 4, on the sides of the side sections 6, additional working bodies (DRO) 8 are installed. The distance between each of the DROs and the side section 6 is determined from the ratio S (B-1 + 2t) / 2, where B is the distance between the extreme POs side sections; 1 - tractor track gauge; t is the distance between adjacent PO sections. When moving the unit RO of the central 5 and lateral 6 sections and DRO cut furrows. When the machine is turning, one of the pairs of wheels 2 or 3 of tractor 1 moves along a furrow formed by one of the DRO. Further passes are made similarly to the second pass. Such processing provides high-quality cutting of furrows and increases the stable stroke of the unit. 2 Il.

The invention relates to agricultural machinery, in particular to aggregates for cutting furrows or ridges for planting potatoes and some other tilled crops.

The aim of the invention is to increase productivity.

Figure 1 shows the tillage unit, a general view; Fig.2 diagram of the passage of the unit on the field

The machine for cutting ridges consists of a wheeled tractor 1 with a right 2 and left 3 pair of wheels and a frame 4 attached to it with sections 5 and 6 of the furrow-forming working bodies, the total number P.

The central section 5 of the working bodies 7 is located in the central part of the frame 4 symmetrically to its middle, while the distance between the working bodies 7 is equal to the working width of one working body 7. The working bodies are not installed on the track line of wheels 2 and 3 of tractor 1. The side sections 6 of the working bodies 7 are located at a distance from the central section 5, equal to twice the distance between the working bodies 7 in the section. On frame 1, additional working bodies 8 are fixed, each of which is mounted at a distance with respect to the lateral section 6, determined from the ratio

„B - 1 + 2t

where B is the distance between the extreme working bodies of the lateral sections;

1 tractor track width; t is the distance between adjacent

working bodies in the section. The support wheels (not shown) are mounted on the frame 4, which, regardless of the position of the tractor 1, orient the frame 4 with the working bodies 7 and 8 horizontally.

The unit works as follows

The first pass in the field is carried out on landmarks, strictly observing the straightness. After the first pass, on the field there remain the grooves formed by the central 5 and lateral 6 sections of the working bodies 7 with the exception of places located on the line of tracks of the wheels 2 and 3, where the raw bands remain, behind the additional work

The organs 8 form separate grooves. On the furrow formed by one of the additional working bodies 8, during the second pass, the pair of wheels 2 of tractor 1 is right.

In this case, similar to the first pass behind the central and lateral sections 5 and 6 of the working bodies 7, grooves are formed, the distance between which is equal to the width of one interstice except for the line of passage of the left pair of wheels 3 of the tractor 1, where the untreated strip remains. Moreover, the additional tool 8, the passage along the track line of the right pair of wheels 3, formed during the first pass, cuts a furrow, and the second additional work body 8 cuts a separate furrow, along which the left pair of wheels 2 of tractor 1 goes along with the subsequent pass. Thus, over the entire area between the centers of adjacent aisles, furrows with a given width between the rows are finally formed. Further passes are made in a manner similar to the second, with only the direction of rotation changing.

Claims (1)

Invention Formula A tillage unit containing a tractor and a frame connected to it, on which the central and side sections are fixed symmetrically about the axis of the unit with the furrow-forming working bodies, and the distance between the central and each of the side sections is equal to twice the distance between the working bodies in the section, characterized in that, in order to increase productivity, it is equipped with additional working bodies mounted on the frame, each of which is installed at intervals with respect to the side section, and The distance between each additional working member and the lateral section is determined from the ratio WITH B -1 + 2t B is the distance between the extreme working bodies of the lateral sections; 1 - tractor track gauge; B is the distance between adjacent working bodies in the section.
