Description

The invention relates to the working bodies of the shredders of the root crops used in agricultural production.

Of; well known working body chopper feed, including radially attached to the rotor blades, placed inside the grating disk Yj. The disadvantage of this working body is the loading of the rubbed feed mass on the outer surface of the grating disc, which significantly reduces its performance and complicates the operational reliability.

The closest to the technical essence of the invention is a working body of a shredder of root and tuber crops, including a rotating grating drum installed in the lower part of the bunker with cutting projections arranged on its surface in rows in a checkerboard pattern, one of the bases of which is open and the other is blocked stub 2q.

The disadvantage of this working body is clogging of the internal cavity of the grating drum with a crushed product, which requires its stopping and cleaning the internal cavity of the grating drum. As a result, the productivity of the working organ is significantly reduced and its operation becomes more complicated.

The purpose of the invention is to increase productivity by preventing the chopped drum from clogging the inner cavity of the crushed product while ensuring uniform cutting of the root and tuber crops throughout its length.

The goal is achieved by the fact that the grating drum has the shape of a truncated cone, the axis of which is set to the horizontal at an angle equal to the angle of inclination of its forming to the height of the cone, while the larger base of the latter is open and its center is located below the center of the smaller base.

. In addition, the rows of cutting protrusions are located on the surface of the grating drum at an angle of 70-85 ° to its axis. FIG. 1 schematically shows a working-body shredder of root and tuber crops; a longitudinal section in FIG. 2 is a view along arrow L in FIG. in FIG. 3, the profile of the cutting protrusions of a grating drum.

The working body includes a drum 2 installed in the lower part of the hopper 1 with windows 3 and cutting protrusions 4 located on its surface in rows in a checkerboard pattern.

The grated drum has the shape of a truncated cone, the axis of which is set to the horizontal at an angle with, equal to the angle of inclination of the generatrix to the height of the cone, so that the upper longitudinal line of the grating drum is horizontal. The larger base 5 is open and its center is located below the center of the smaller base, which is blocked by the plug 6. The rows of the cutting protrusions 4 are located on the surface of the grating drum at an angle B to its axis, equal to 70-85 C.

The grating drum is rigidly mounted on the shaft 7, which is mounted in bearings 8.

The crushing of the root crops by the working body is carried out as follows.

Rotated tubers are fed to the rotating grating drum 2 from the hopper 1, which are crushed by the action of the cutting protrusions 4. The crushed product, having passed through windows 3, is thrown inside the grating slabane. Due to the slope of the lower part of the latter, as well as under the action of forces arising during its rotation, the crushed product is automatically removed through the open base 5 to the outside. Due to the arrangement of the rows of cutting protrusions at an angle of 70-85 ° to the axis of the grating drum, the roots and fruits are moved along the grating drum, which intensifies the grinding process.

With this performance of the working op. In this case, the inner cavity of the grating drum is prevented from being crushed by the crushed product, at the same time conditions are provided for uniform cutting of root and tuber crops throughout its length. The working body is simple in design, convenient and safe in operation.
