Abstract

The utility model relates to agricultural machinery, mainly to tillage tools. The plow body includes a right share with a protruding chisel-like toe, a left share that is shifted backward in the direction of movement relative to the right share, a blade, a shoe, for fixing working bodies and a rack. In this case, the cutting edge of the left share is located 30 ... 100 mm above the plane of the cutting edge of the right share. The forming arc of the blade is twisted, so the blade is a half-screw or cultural form, or the blade can be made feather. In addition, in the upper front part of the blade, an angle pick is installed, or a skimmer is installed in front of the front part of the blade. As an additional option, a fixed knife or a movable circular knife can be installed in front of the leading edge of the blade. Thus, this housing design improves the quality of the plow.

Description

Known plow body, RU No. 89319 dated 12/10/2009, containing a ploughshare, blade and means for attaching them to the stand. In addition, it includes additional cutting elements, the first of which is made in the form of a flat plate with a blade part located in the cutting plane at an angle of 75-110 ° to the blade part of the share. The second cutting element is made in the form of an arched plate containing sharp blade working parts converging at an acute angle on the wide and narrow sides, which are placed in front of the plow body so that the blade part of the narrow side of the arched plate is in the plane of the blade parts of the share and the first additional cutting element, and the non-working sides of the arcuate plate are adjacent to the front of the blade wing. Moreover, the ploughshare, blade, the first and second cutting elements are mounted on the rack using at least one attachment unit consisting of steel plates equipped with holes in the area of the landing sites for bolting the indicated parts of the plow body.

With the translational movement of the plow, its working bodies are buried in the soil to a depth set by the support wheels. Cutting the formation in the proposed plow body is provided by three rusting elements - vertical and two horizontal, installed according to the scheme, providing mutual balancing of the forces acting on them. In this case, a vertical knife and a right-hand share of right-side action cut off the main part of the formation (most of the working width of the body), crumble it, wrap it and move it into the furrow together with the loosened part from the passage of the additional left-side cutting element (left share) from the previous body. The remaining smaller part of the formation is cut and loosened by the left share, which simultaneously plays the role of a stabilizer of rectilinear movement. Thus, the total working width of this plow body is much larger than a conventional plow. The use of this housing increases the productivity of the plow and reduces fuel consumption per unit of cultivated area.

If in a conventional plow the field board performs a passive role, creating additional resistance due to friction, then the left ploughshare (additional cutting element) performs two functions - the function of the field board, balancing the torque of the right ploughshaft and the additional cutting of the layer on the left.

The disadvantage of this case is the lack of a protruding nose in front of the cutting edges, which affects the depth of the body, up to the loss of performance, especially when working on solid soil. The use of a vertical cutting edge does not give any positive effect and, in fact, does not differ from the use of a disk or fixed knife, which, as an additional option, can be installed and are mounted on the body of a conventional plow. The cylindrical blade used in the proposed plow body crumbles well, but poorly turns the layer of earth. In addition, the blade in the proposed plow body is shortened and turns over only part of the land. The part of the earth, loosened by the left share, is displaced without a turn of the formation. Since the cutting edges of the right and left shares are in the same plane, cutting of the earth with the left shares is quite deep. Damage to the root system of weeds practically does not occur. And the displacement of loose soil occurs throughout the depth of processing. Thus, almost intact weeds are quite close to the surface, slightly sprinkled with the part of the earth that turned upside down. In case of rain, the sprinkled weed re-sprouts. Therefore, the quality of work on the clogged field of such a plow body is low. The main disadvantage of this plow body is the incomplete and shallow incorporation of plant residues.

Known working body of the tillage implement (prototype), RU No. 93616 dated 05/10/2010, including right-side and left-side shares, stand and base for securing the stand and shares. Moreover, the length of the left-side share is at least 1/3 of the length of the right-side one, and the plow angles relative to the direction of movement are selected from the range of 30-60 °. Moreover, it is equipped with a blade mounted on a stand on the right side at an angle of 15-60 ° to the direction of movement, the right-hand share is made with a protruding toe, while the stand is made flat with curved front and rear end surfaces of an arcuate shape. The right-hand share is offset from the left-hand share in the direction of travel. The protruding toe of the right-hand share is chisel-shaped with a straight cutting edge. The cutting edge of the protruding toe of the right-hand share is made curved. The angles of inclination of the plane of the left-side and right-side shares to the plane of the base of the working body are 20-35 °. The cutting edges of the left-side and right-side shares are located in the same plane. The cutting edge of the protruding toe of the right-hand share is offset 2-6 cm downward relative to the cutting edges of the left and right-hand share. The rack is equipped with a fairing fixed from the front end surface. The blade of the working body is made curved of a metal sheet bent along the radius, while the upper angle of the blade remote from the rack is bent along the direction of movement of the gun. The blade is removable, while the angle formed by the bottom edge of the blade and the base of the working body, has a value of up to 30 °.

With the translational movement of the tillage implement, its working bodies are buried in the soil to a depth set by the support wheels. At the same time, the right ploughshare cuts off the main part of the formation (most of the working width of the enclosure), then the blade, crumbles it, wraps and moves into the furrow together with the loosened part from the passage of the left ploughshare from the previous casing. The remaining smaller part of the formation is cut and loosened by the left share, which simultaneously plays the role of a stabilizer of rectilinear movement. Thus, the total capture width of this working body of the tillage implement is much larger than the body of a conventional plow. The use of this working body increases the productivity of tillage tools and reduces fuel consumption per unit of cultivated area.

If in a conventional plow the field board performs a passive role, creating additional resistance due to friction, then the left ploughshare performs two functions - the function of the field plow, balancing the torque of the right ploughshaft and the additional layer cutting function on the left.

Curved in radius, a cylindrical blade used in the proposed working body of a tillage implement crumbles well, but does not turn over a layer of earth well. In addition, the proposed working body of the tillage implement turns over only part of the land. The part of the earth, loosened by the left share, is displaced without a turn of the formation. Since the cutting edges of the right and left shares are in the same plane, cutting of the earth with the left shares is quite deep. Damage to the root system of weeds practically does not occur. And the displacement of loose soil occurs throughout the depth of processing. Thus, almost intact weeds are quite close to the surface, slightly sprinkled with the part of the earth that turned upside down. In case of rain, the sprinkled weed re-sprouts. Therefore, the quality of work on the clogged field of such a plow body is low. The main disadvantage of this plow body is the incomplete and shallow incorporation of plant residues.

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

The technical result is achieved due to the fact that the plow body includes a right ploughshare with a protruding chisel-like toe, a left ploughshare shifted backward in the direction of movement relative to the right ploughshare, a blade, a shoe, for securing the working bodies and a stand. In this case, the cutting edge of the left share is located 30 ... 100 mm above the plane of the cutting edge of the right share. The forming arc of the blade is twisted, so the blade is a half-screw or cultural form, or the blade can be made feather. In addition, in the upper front part of the blade, an angle pick is installed, or a skimmer is installed in front of the front of the blade. As an additional option, a fixed knife or a movable circular knife can be installed in front of the leading edge of the blade.

In FIG. 1 shows a plow body, front view.

In FIG. 2 shows a plow body, top view.

In FIG. 3 shows the plow body, left view.

The plow body includes a right share 1 with a protruding chisel-like toe 2, a left share 3, shifted backward in the direction of movement relative to the right share, blade 4, shoe 5, for securing the working bodies and stand 6. At that, the cutting edge of the left share is located at 30 ... 100 mm above the plane of the cutting edge of the right share. The forming arc of the blade is twisted, so the blade is a half-screw or cultural form, or the blade can be made feather. The figures show a feather blade. In addition, in the upper front part of the blade, an angle of 7 is installed, or a skimmer is installed in front of the front of the blade. As an additional option, a fixed knife 8 or a movable circular knife can be installed in front of the leading edge of the blade. The figures show a plow body of a right-handed action. In the case of execution of the left-handed housing for the reversible plow, the arrangement of the working bodies should be in a mirrored design.

The plow body works as follows. With the translational movement of the plow, its working bodies are buried in the soil to a depth set by the support wheels. At the same time, the right share 1 cuts off the main part of the formation (most of the working width of the enclosure), if necessary, in case of increased weediness of the field, a fixed knife 8 or a disk movable knife are installed on the body, which helps to cut off the main part of the formation. Next, the blade 4, crumbles it, wraps and moves into the furrow, together with the loosened part from the passage of the left share 3 from the previous building. Moreover, due to the fact that the left ploughshare is located above the right, the lower part of the soil after the passage of the left ploughshare remains in place, and only the upper loosened soil layer is displaced into the free furrow. Consequently, the displaced layer will be 30 ... 100 mm lower from the surface of the earth than that of analogues. Accordingly, the layer of land above the shifted weeds will be larger. This will be enough to prevent the germination of the weed. The remaining, smaller part of the formation is cut and loosened by the left share 3, which simultaneously plays the role of a stabilizer of rectilinear movement. Thus, the total capture width of this working body of the tillage implement is much larger than the body of a conventional plow.

It is well known that for good loosening of the formation, a complete turn of the formation is not necessary. Usually a rectangular cut-off layer of earth is not completely wrapped and placed at an angle. This is ensured by the use of cultural and semi-screw dumps, as used in the claimed design of the plow body. However, in this case, the crop remains and the weed will not be covered in the upper corner of the inverted bed. It is well known that plowing should be clean, this angle of the formation must be thrown into the furrow before the main formation. This is done either by a filthy or skimmer. In this design of the plow body, the installation of either a skimmer or an angle of 7 is foreseen. Thus, a complete 100% termination of plant residues is ensured.

Thus, this design of the plow body improves the quality of the plow.
