Abstract

The slit-cutting working body for subsurface tillage refers to agricultural machinery, in particular to tools for cultivating soil on slopes and flat terrain in areas where water and wind erosion are present. The purpose of the invention is to improve the quality of crumbling and lower traction resistance. The slit-cutting working member for moldless tillage contains a cutting stand with a flat-cutting paw and flexible elements, some ends 4 and 5 of which are fixed on the foot, and the other are connected to the drive mechanism, the drive mechanism being made in the form of a two-arm bracket pivotally mounted at the top of the rack. The paw is located above the lower end of the rack. The wing of the plane cutter is connected to the stand by means of a flexible element and is located with it in the same plane. The ends of the flexible elements to the wings of the legs 2 and the two-arm bracket can be connected by holes drilled on the wings of the legs and on the two-arm bracket. The paw is pivotally attached to the stand. On the lower rear side of the rack 1 there is a semi-cylindrical groove, a slot, and also holes with an internal thread. The finger with holes, the passage through the holes available at the toe of the paw, is secured by fasteners to the rack. The rack is mounted on the frame by bolted connections. 1 s.p. f-ly, 6 ill.

Description

The invention relates to agricultural machinery, in particular to tools for soilless tillage on slopes and flat terrain in areas of spread of water or wind erosion of soils.

The purpose of the invention is to improve the quality of crumbling and reduce traction resistance.

In FIG. 1 shows a working body, side view; in FIG. 2 - the same.or l, front view; in FIG. 3 - it is in axonometry; in FIG. 4 - flat-cutting paw, top view: in FIG. 5 - views, parts of the connection

paws to the rack in a perspective view; in FIG. 6 - the technological process of the working body (after the passage).

The slit-cutting working body for subsurface tillage contains a cutting stand 1 (Figs. 1, 2 and 3) with a flat-cutting foot 2 and flexible elements 3. one ends 4 and 5 of which are fixed to the foot 2, and the other 6 and 7 are connected to the drive mechanism 8 moreover, the drive mechanism 8 is made in de hinged 9 mounted in the upper part of the rack 1 two shoulders 10 and 11 of the bracket 12, the leg 2 is located above the lower end 13 of the rack 1.

associated with the rack 1 by means of a flexible element 16 and are located with it in the same plane. The ends of 4,5, 6 and 7 of the flexible elements 3 to the wings 14 and 15 of the legs 2 and two shoulders 10 and 11 of the bracket 12 can be connected with holes 17 and 18 (Fig. 3 and 4), drilled on the wings x 14 and 15 paws 2 and on two shoulders 10 and 11 of the bracket 12. The paw 2 is pivotally mounted 19 to the rack 1. On the lower rear side of the rack 1 there is a semi-cylindrical groove 20 (Fig. 5), a slot 21, and also holes 22 with internal thread. The finger 23 with holes 24, the passage through the holes 25, which are available on the nose; the paws 2 are fixed with fasteners to the rack 1. The rack 1 of the slit working body is mounted on the frame 26 by bolt connections 27.

The working body works as follows.

When the working body moves, its rack 1 opens a slot in the form of a slot 28 in the soil to a depth of Hi + N2 (Fig. 6), where Hi is the depth of plowing; H2 is the depth of processing of the subsurface layer. In this case, the plane-cutting leg 2 moves along the horizontal slot 29 left behind the flexible element 16 (Figs. 1 and 3). The vertically obliquely mounted flexible elements 3, a cut of the shavings 30 from the soil layer, were loosened heavily. In this case, there is no violation of the structural structure of the soil in height. 3 shavings 30 of soil upi cut off by flexible elements.

they collide at an acute angle a relative to the vertical axis.

Using the proposed working body, the quality of the soil cultivation is improved, the traction resistance of the aggregate is reduced, self-cleaning soil is self-cleaning due to small fluctuations in the soil of the paw system - flexible elements - bracket, there is no compacted sole of the subsurface horizon, soil water absorption increases due to the destruction of dense subsurface layers the soil. In addition, after the passage of the working body, stubble stubbornness of the soil is preserved, which improves the conditions for combating wind and water erosion of the soil.

Claims (2)
