Abstract

FIELD OF THE INVENTION The invention relates to Agricultural Machinery, namely, the working bodies of machines for inter-row tillage. The purpose of the invention is to improve the quality of preparation of the soil ridges on the soil while reducing damage to plants. The working body of the cultivator contains a stand 1 with a paw 2 and 4.5 dumps 6.7 fixed on the share plow, located above the rear edges of the plowshares 4.5, flying back beyond their cutting edge and having adjustable pads 8.9. The dumps 6.7 are installed vertically, and the pads 8.9 are made of rubberized material and installed by means of a flat spring 10 located adjacent to the surfaces of the pads 8, 9 on the back side of the latter. When working, the blades b, 7 and pads 8, 9 form the soil ridge on the protective zone and powdered weeds. 3 il.

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to working bodies for inter-row tillage mounted on the frame of a cultivator.

The purpose of the invention is to improve the quality of preparation of dump soil crests while reducing damage.

Figure 1-3 shows the working body of the cultivator.

The working body of the cultivator includes 1 lancet paw 2 mounted on the rack and placed offset to the toe.

3paps 2 on the rear edges of shares of plowshares 4 and 5 dumps 6 and 7. Tops of dumps 6 and 7 are located above the rear edge of plowshares

4 and 5 with a departure back for its back edge. Dumps 6 and 7 on the plowshares 4 and 5 are installed vertically. At the remote ends of the dumps 6 and 7 are placed the rotary plates 8 and 9. The plates 8 and 9 are made of rubberized material. Each lining 8 (9) is installed by means of a flat spring 10 located adjacent to the surface of the lining 8 (9) on the back side of the latter. The lower part of the blade 6 (7) is located with the overhang of the rear edge of the plowshare 4 (5) The front ends of the pads 8 and 9 are connected to the dumps 6 and 7 using axles 11, and the rear ends are bolts 12 with a countersunk head and screws - thumb 13. Rotary lining 8 and 9 are provided with arc grooves 14, providing adjustment of the height of the lining 8 (9) over the plowshare 4 (5).

The working body of the cultivator operates as follows.

When moving in the soil, the toe 3 and plowshares 4 and 5 undercut the soil layer with weeds, simultaneously crumbling the soil layer. The soil layer in the middle of the paw 2 from the toe 3 descends to the left and right of the strut 1, leaving an even layer in the middle of the treated floor.

sy. The soil layer, cut by the plowshares 4 and 5, goes to dumps 6 and 7, respectively. By the dump 6, the loose soil layer is guided through the plowshare 4 to the overlay 8. The pad 8 dampens the speed of the soil layer from the dump b, because the strength of the soil friction on the rubber pad is 3 ... 4 times more than the strength of the soil friction on the steel blade. The lower edge and the furrow edge of the lining 8 form the soil ridge ridge above the protective zone, the weed seeds. The deviation of the lining 8 together with the flat plate 10 upon meeting with the stalks of the plants excludes their mechanical damage. When the second and third cultivation is carried out, the overlay 8 is turned upwards relative to the axis 11, having preliminarily released the bolt 12 with the thumbscrew 13 in the arc groove 14. In this case, a dump ridge of greater height is formed. Otherwise, the technological process of inter-row tillage in caring for wide-width crops using non-herbicidal technology is carried out on the right side of the working body in the same way.

The working body of the cultivator with the high quality of work performs inter-row caring for row crops. The application of the proposed working body on the example of butchering maize allows for deep inter-row processing with hilling in rows in the early phases of maize growth and development (phase 5-6 leaves), when it is particularly sensitive to weeds. Deep loosening in combination with hilling in rows creates a powerful mulch layer of soil (at least 8-10 cm), which prevents the formation of cracks, destroys weeds in rows and between rows, and thereby contributes to the maximum retention of moisture in the soil and. increase of corn productivity, especially in the dry years by 5-8 centners / ha.
