FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to the working bodies of the plows.

The purpose of the invention is to reduce traction resistance by improving the process of cutting formation.

FIG. 1 shows the plow body,

view from above; FIG. 2 is the same, front view; in fig. 3 - the same, side view; in fig. 4 shows a section A-A in FIG. 1 in FIG. 5, a diagram of cutting a layer of soil in a transverse-vertical plane passing through the joint of field cut-offs of the blade and plowshare; Fig. 6 is a diagram of the variation of the furrow width (Vsh, By) and the height Ah of raising the centers C, Ci of the mass of the reservoir section depending on the angles () i and Cp between the field edges of the blade and the plowshare.

The plow body contains a stand 1, a field board 2, a ploughshare 3 and a blade 4. The field cut-off ab of the plowshare 3 is located in the longitudinal-vertical plane, and the field cut-off bd of the blade 4 is curved and convex in the direction of motion. The angle 0 and cp between the straight line connecting the ends of the field crop bd of blade 4 and the field crop ab of the plowshare 3 are respectively 80-85 ° in the horizontal plane and 145-150 ° in the transversely vertical plane. Prma, Passing through the ends of the upper half

According to the parameters of the blade 4 working surface, the treated layer has a r1 orhombic shape in cross section, and cutting off the layer from the furrow wall occurs at the very beginning of its rotation. Proposed

the range of variation of the angles θ and q, the relative position of the ab and bd field cuts, and the spatial position of the field cut-off bd of the blade 4 improve the cutting process of the reservoir while separating it from the soil monolith, allow choosing the optimal values

furrow widths (Vsh, By), if necessary, reduce energy consumption by reducing the increase in i.h of CjCg centers of formation masses.

The use of the proposed plow body will (compared to the known ones) reduce energy consumption, improve the quality of tillage and the conditions of movement of the arable farm.

Invention Formula A plow body comprising a stand, a field board, a ploughshare with a field edge located in a longitudinal-vertical plane, and a blade with a curved field edge that is convex toward the direction of motion, characterized in field cut-off cd blade 4, located, that, in order to reduce traction burned. at an obtuse angle to the field cut-off ab of the plowshare 3. The sock I of the plowshare 3 is located in front of or at the same level in the longitudinal-vertical plane with the field cut-off of the bd blade 4. The plow body works as follows. The soil layer is cut off by the blade of the plowshare-3 from the bottom of the furrow, and the field edge ab of the plowshare 3 and the field edge bd of the blade 4 from the wall of the furrow. Then the reservoir enters the working surface of the blade 4 and moves with a turn to the adjacent furrow. According to 45 by improving the cutting process, the angle between the straight line connecting the ends of the field edge of the blade and the field edge of the share plow blade is 80-85 ° in the horizontal plane and 145-150 ° in the transverse-vertical plane, through the ends of the upper half of the field edge of the blade, located at an obtuse angle to the field edge of the share plowshare, and the toe of the plowshare is located in front or at the same level in the longitudinal vertical plane with the field edge of the blade. that, in order to reduce heavy fuel consumption Resistance by improving the cutting process, the angle between the straight line connecting the ends of the field edge of the blade and the field edge of the plowshares is 80-85 ° in the horizontal plane and 145-150 ° in the transverse-vertical plane, and the ends of the upper half of the crop edge of the blade is located at an obtuse angle to the field crop of the plowshare, and the toe of the plowshare is located in front or at the same level in the longitudinal-vertical plane with the field edge of the blade.
