Description

The invention relates to the field of agricultural engineering, namely to tillage implements, and can be used for

Covering the vineyards of the soil shaft. The purpose of the invention is to improve the quality of tillage. The tillage bracket contains side racks 2, 3 mounted on the frame 1, 3 with the cutting edge 4 fixed on them. After the share 4, there is an extender-ripper 5. The latter is made of two rigidly interconnected parts 6.7. The lower part 6 is rigidly fixed on the plowshare 4 and has the shape of a conical surface with a convex downward direction and an apex directed backwards. The upper part 7 is hinged on one of the side posts and the frame 1 and has the shape of a conoidal surface, facing backwards and convex at an angle to the direction of movement. When moving the staples, the side posts 2, 3 and the plowshare 4 undercut the soil layer, and the ripper 5 shifts it to the side and wraps it. 2.

The invention relates to agricultural machinery, namely, tillage implements, and can be used for covering the soil (. Shaft shaft of vineyards for the winter.

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

FIG. 1 shows a soil tillage bracket, side view, in FIG. 2, section A-A in FIG. one.

The soil tillage bracket contains side racks 2 and 3 mounted on frame 1 with scotch 4 fixed on them. The 15th is the extension-loose * · tel 5. The latter is made of two rigidly interconnected parts 6 and 7, the lower 6 of which are rigidly fixed on the plowshare 4 and have a conical surface shaped downward and convex upward. Top part. 7 of the ripper 5, hinged to the side stand 3 and on the frame 1 and 25 has the shape of a conoidal surface, facing backward bulge and located at an angle y to the direction of movement. The top of the conical part 6, 8 arranged at the trailing edge 30 conoid portion 7 from the side of the rack 2 at a height H equal to the depth processing, wherein the generatrix of the conical portion 6 is aligned with the generatrix conoid portion 7. Since the rack ₃₅ of the side 2 in the conical portion 6 is secured the guide element 9 having the shape of a convexly turned upward conical surface. ₄₀

Tillage bracket works as follows.

When moving the staple layer of soil is cut by the plowshare 4 and the side racks 2 and 3. Moving along the working surface _{45 of} the extender-ripper 5,

cut layer of soil, having a semicircular shape at the bottom, in contact with the conical part

6 fits into its shape and with minimal deformation enters the conoidal part 7. At the same time, the reservoir has a maximum lifting height above the bottom of the furrow. Conoidal part

7 shifts the stratum to the side, wraps it and puts it in the covering shaft. The gradual increase in the curvature of the conoidal part 7 along the course of the plate gives it a smooth twist, as a result of which it collapses only after it is removed from the working surface due to the torsion deformation

at the time of laying in the covering shaft. The guide element 9, supporting the reservoir, contributes to its complete turnover. The angle is adjusted depending on the soil and speed conditions.

Claims (1)

Claim A soil tillage bracket containing side racks mounted on the frame with a scooping blade fixed to them, behind which is an extender-ripper, about t. the parts, the lower of which is fixed on the share, has the shape of a conical surface, turned downwards with a convexity and directed backwards, and the upper part of the ripper extension is hinged on one of the side posts and the frame has yoke conoid surface facing convex back and angled to the direction of movement. 1366072
