Description

(54) APPARATUS FOR CUTTING AND CUTTING

.one

The invention relates to an agricultural machine-building industry 1 and is intended for heavy pruning of tea bushes with simultaneous shredding.

A known apparatus for trimming and shredding bushes, comprising a casing, inside of which a cutting body is placed and above it with a displacement a rotary chopper 1.

A disadvantage of the known device is that it does not ensure complete capture and grinding of the cut mass on the cylindrical surface of the bush.

The purpose of the invention is to increase the degree of grinding of the cut mass.

This goal is achieved by the fact that Kbzhukh in the front part above the cutting body is equipped with a socket and conflicting knives mounted above the rotor grinder, the surface of which is made concave.

FIG. shows the proposed apparatus, front view; in fig. 2 - the same, side view; in fig. 3 - kinematic diagram of the apparatus.

The apparatus contains a casing 1, inside which is placed the cutting body 2 and above it

with offset rotary chopper 3. The casing 1 in the front part is equipped with a bell 4 and opposing knives 5 mounted above the rotor grinder 3, the surface of which is made concave as a broken line. The casing 1 ends with two diverging and open from the bottom nozzles 6 for dropping part of the ground mass under the crown of the bushes.

The drive of the working bodies is carried out from the PTO of the self-propelled chassis. By means of the cardan shaft 7, the bevel gear 8 and the belt gear 9 rotate the rotary chopper 3, and by means of the chain gear 10, the sprocket 1 and the crank shaft 12 transmit the reciprocating movement.

 The device works as follows. When the mashina moves along the tea bushes, the cutting body 2 cuts the branches at a given height to give the bushes a cylindrical shape, and the socket 4 presses and compresses the branches of the bush covered by it, thereby improving the condition of the cut. Then, cut branches fall onto a rotary chopper 3, where as a result of the interaction of the shredder knives and the shearing knife 5, the cut mass is crushed, part of which remains on the bush as a protective layer against frost, and part of it is fed under the crown of the bushes. Due to the fact that the chopper configuration corresponds to the configuration of a segment-cutting apparatus that produces a semi-semi-pruning to make the bushes cylindrical in shape, the entire cut mass is crushed over the entire surface of the bush. The proposed apparatus allows the bushes to quickly restore their former shape and order the most to expand the area of plantations for gathering. When conducting semi-half-pruning tea bushes with simultaneous chopping of cut branches, organic fertilizer is saved due to the crushed mass. The combination of two operations into one (trimming and grinding) reduces labor costs for trimming tea. The invention The apparatus for trimming and shredding bushes, comprising a casing within which a cutting body is placed and a rotary chopper with offset, characterized in that, in order to increase the degree of grinding of the cut mass, the casing in the front portion above the cutting body is equipped with a bell and opposing knives mounted on a rotary grinder, the surface of which is made concave.
