Description

 The invention relates to agricultural machinery, in particular to plows for smooth plowing.

 Known plow body, including a stand with a mechanism for its rotation, a share mounted on it with two socks and a blade, the field and furrow cuts of which are located symmetrically with respect to a vertical plane perpendicular to the share blade and passing through its middle, and are curved in shape with a flight to the side furrows and not more than half the width of the grip of the body.

 A disadvantage of the known plow body is the absence of a field board providing a supporting surface for the stability of the body movement.

 The purpose of the invention is to increase the stability of the plow body along the width of the grip and reduce its traction resistance by installing left and right field boards.

 This goal is achieved by the fact that on the plow body in the lower part of its rack are installed field boards, which are located at an angle and in mirror image to each other. Since the length of the field board is limited by the line of intersection of the planes of the field boards, their area is insufficient to balance the lateral pressure of the soil during the operation of the housing. To increase the area of the field board, an additional rotary field board is installed in the lower part of the plow body rack so that its axis of rotation coincides with the intersection line of vertical planes passing through the middle of the additional field board with its right and left working positions. The working (vertical) planes of the main and additional field boards coincide. The additional field board during the operation of the housing alternately occupies the extreme left or right positions and self-installs under the influence of the soil reaction forces so that it is a continuation of the main field board. In addition, depending on the strength of the furrow wall to adjust the position of the additional field board relative to the direction of movement (GN Sineokov, Designing tillage machines. M .: Mashinostroenie, 1965, p. 212), the emphasis is made adjustable in thickness, for example, using a telescopic screw .

 To increase the stability of the plow body stroke along the working width and reduce its traction resistance, the main and additional rotary field boards with the axis of rotation in the center of the intersection lines of the vertical planes passing through the middle of the additional board with its right or left working position are installed in the lower part of the plow body, while the working planes of the main and additional field boards coincide. Thus, the claimed plow body meets the criterion of "novelty."

 In FIG. 1 shows a plow body, side view; figure 2 is the same, bottom view; figure 3 - adjustable thickness stop; figure 4 - the location of the adjusting screws on the main field board.

 The plow body consists of a swing mechanism with a stand 1 with a share 2 mounted on it with two socks 3 and a blade 4. On the bottom 1, the hinge axis 5 of the additional field board 6 is attached from below. The additional field board has both planes working and depending on the working (right or left) side of the housing alternately occupies the left or right position. The front end of the additional field board has a stop 7 with adjusting screws 8 and 9, which, when the board is rotated, alternately abuts against the rear side of the main field board 10. When the adjustment screws 8 and 9 are located on the back of the field board 10, the thickness of the stop 7 remains unchanged. At the first pass of the implement, the plow body is turned, for example, to the right. At the time of deepening the plow, as the hull enters the soil, the additional field board 6 is located on its working plane along the movement of the aggregates with the plane of the left main field board 10. When the plow body reaches the required depth, the wrapped soil layer acts through the blade 4 on the body, which begins to shift towards the furrow wall and abuts against it with the plane of the field board 10 along the entire contact line about the furrow, including the additional field board 6, the further rotation of which limits with emphasis 7. On the second pass, the housing turns to the left (such a condition for smooth plowing) and, when deepened, the additional field board occupies the right position, and so on.

 The use of the proposed plow body will reduce the traction resistance of the implement, improve the quality of tillage and increase crop yields.
