Description

The plowshare 5 is equal to the distance of the last to the bottom of the toe of the element 8. The latter is made of sheet metal 12 mm thick, and its cutting edges 10 have a sharpening angle of 30 °. A wear-resistant alloy is deposited on the cutting edges 10 of the loose element .8, while it is made symmetrical and all its faces can work.

Loosening element 8 may have an X-shaped form, while its upper and lower ends are made of two parts arranged at an angle to each other and form inclined struts 11, 12, 13, 14. In the middle part of the loosening element 8 a hole 15 is made to connect to the threaded axis 16 of the shoe 4; The cut of the axis 16 is eliminated by grooves 17, one of which covers the back edge 7 of the shoe 4 in working position. The front and rear cutting edges of the racks 11, 12, 13, 14 have a sharpening angle of 20 ° and deposited with sormoytym. As the pillars 11-14 wear, the loosening element 8 rotates through an angle of 180 ° and is fixed in the hole 15 by the threaded axis 16.

Loosening element 8 may be made in the form of multidirectional bars 18,

19. The latter may have a cylindrical shape with a diameter of 30 mm. The installation angle of the bars 18, 19 to the direction of motion is 40 °. The bars 18, 19 have oblique cuts

20, which are located at an angle of 30 ° to the axis of the bars 18,19. The latter are fixed on the shoe 4 with a threaded axle 21.

The bars 18, 19 may have a tetrahedral shape and are placed in inclined square holes 22, 23. The ribs 24 of the bars 18, 19 are directed towards the direction of movement.

The rods 18, 19 may have a hexagonal shape and are directed by faces 25 in the direction of motion. Angular recesses are made on the facets x 25, which are deposited with wear-resistant material 26. Similar angular recesses are made on the faces of the counters 11-14, which are also welds with wear-resistant material 26.

The working body for loosening the soil works as follows.

When the working body moves, the soil is cut by the ploughshare 5, rises along its inclined surface and further along the surface of the shoe 4 reaches the loosening elements 8, while the fertile layer is cut by their upper cutting edges 10 into vertical parts and is crumbling intensively. At the same time lower cuts.

The edges 10 of the loose elements 8 destroy the plow base. The soil behind the loose elements 8 closes with the soil of the plow sole.

The inclined stands 11-14 cut the arable layer into the soil layers and produce intensive destruction of the plow base by the stands 13, 14.

Upon receipt of a layer of soil from the plowshare 5 on the bars 18.19 last raise it
