Abstract

The invention relates to agriculture and can be used for primary tillage, on the surface of which there is unbound organic material, such as straw, green manure, manure, etc. It makes it possible to improve the quality of tillage by better incorporating organic matter and preventing clogging of the working parts of the gun. To do this, during plowing, before cutting off the field body, a part of the reservoir is cut off, displaced to the surface, and held on to the floor before turning and laying the remaining part of the reservoir into the furrow. This process is realized by means of a gun, in which the plowshaped bodies are successively fixed to the frame and in front of each of them is a spherical disk mounted at an angle to the direction of movement and facing with a convex part towards the furrowed edge of the body. Each disk is located above the share of the corresponding body and is shifted to the side of its furrow cut, part of the cutting edge of the disk located on the side opposite to the direction of movement relative to the axis of rotation of the disk is located above the bottom of the field edge of the body blade. 2 sec. f-ly, 2 ill. with s

Description

The invention relates to agriculture and can be used for primary tillage, on the surface of which there is unbound organic material, such as straw, green manure, manure, etc.

The purpose of the invention is to improve the quality of tillage.

Figure 1 shows the implement for tillage; figure 2 - flowchart.

The tillage implement contains frame 1 on which

plow-mounted shells 2 are mounted. In front of each case, a spherical blade disk 3, with a convex part facing the furrow cut-off of the body, is fixed with the possibility of adjusting the angle of attack and depth of travel. Setting the angle of attack of the disks and the depth h of their stroke depends on the physicomechanical properties of the soil and the depth of the main treatment, as well as on the characteristics of the organic material and its thickness on the floor surface. Each disk is located above the share of the corresponding body and is shifted in the direction of its furrow

crop cut. The indicated displacement (. (FIG. 2) can have a value from zero to mn / 2, i.e. up to half of the greatest cross-sectional width of the groove formed by the disk.

In this case, the disk is mounted so that a part of its cutting edge, located on the side opposite to the direction of movement relative to the axis of rotation, is placed above the lower part of the field edge of the body blade. Such an arrangement provides, in a projection onto a longitudinal-vertical plane, the intersection of this part of the cutting edge with the field edge of the blade.

The method of tillage is implemented as follows.

When the gun moves, the disk 3 cuts the soil in front of the body 2 in the upper part of the reservoir 4 and together with the organic material located on it, displaces it to the surface, laying it in the form of a roller and forming a furrow free from organic matter. The dumping body next to the disk cuts and turnover of the remaining reservoir. The overlapping of the field edge of the blade by the cutting edge of the blade ensures the retention of the mixture of soil and organic matter (roller) cut on the surface of the floor until the remaining part of the formation begins to turn. After this, part of the mixture is poured to the bottom of the furrow formed. The displacement of the disk (in the projection on the frontal plane, this displacement f of the axis of its symmetry from the field edge of the blade) towards the furrow cut-off from zero to mn / 2 provides, within these limits, an area free from organic matter for the passage of the field edge of the blade and prevents it clogging. At the same time, depending on the angle of attack of the disk and the magnitude of its mixing P, the roller from soil and organic matter is placed closer or farther from the furrow and, accordingly, in

it is further embedded deeper or smaller. The larger the value of T, the closer to the edge of the floor is the roller and the deeper organic matter is embedded 5.

The use of the invention will allow

improve the quality of the placement of organic matter and at the same time eliminate the clogging of the working bodies of tillage implements, i.e. improve the quality of the main tillage and

her fertility.

Fo rmu l and z o b r e n i 1. Method of tillage, including cutting off the upper part of the layer of soil

before the field cutting of the plow body, the displacement of the cut part of the formation to the surface of the floor from the field edge of the body and the subsequent rotation and laying of the remaining part of the formation into the furrow, which differs

By the fact that, in order to improve the quality of tillage, the cut part of the soil layer keeps the floor on the surface before turning and laying the remaining part of the layer in the furrow.

2. A tillage implement containing plow bodies successively mounted on a frame, in front of each of which is mounted a spherical disk, angled to the direction of movement and facing with a convex part towards the furrow cut of the plow body, in order to improve the quality of tillage, spherical disk of each of

The plow bodies are located above the share of the plowshare and are shifted towards its furrow cut, while the part of the cutting edge of the disk is located on the side opposite to the direction of movement relative to the axis

disk rotation is placed above the lower part of the field edge of the plow body blade.

Claims (2)

Claim 1. A method of tillage, including cutting the upper part of the soil before the field edge of the plow body, shifting the cut part of the layer to the field surface from the field edge of the body and subsequent rotation and laying of the remaining part of the layer into the furrow, characterized in that, in order to improve the quality of processing soil, the cut-off part of the soil layer is kept on the surface of the field until the turnover and laying the remaining part of the formation in the furrow. 2. A tillage implement containing plow bodies sequentially mounted on the frame, in front of each of which there is a spherical disk located at an angle to the direction of movement and facing the convex part towards the furrowed edge of the plow case, characterized in that, in order to improve the quality of soil cultivation, the spherical disk of each of the plow bodies is located above the share and is shifted towards its furrowed edge, while the part of the cutting edge of the disk located on the side opposite to the direction movement relative to the axis of rotation of the disk, is located above the lower part of the field edge of the blade of the plow body.
