Description

one

The invention relates to milling machines for the preparation of charred lands for agricultural use and the developed peat deposit layer for exploitation.

The purpose of the invention is to increase the effectiveness of the operation of the tool when grinding shrubs and wood inclusions.

Figure 1 shows a milling tillage tool, side view; figure 2 is the same, bottom view; in FIG. 3, view A in FIG.

The tool contains a frame 1, mounted on it a milling cutter 2 with disc-shaped knives 3, a casing 4 and in front of the milling cutter 2 a baffle plate 5 with a shear knife 6,

On the bottom surface of the fender plate 5, the ribs are fixed in the form of a plate 7, which are connected to each other at an angle and form longitudinal grooves 8. The joints 9 of the plates 7 are oriented along the longitudinal axis of the cannon, while those of the joints 9,

which are addressed to; baffle plate 5, located opposite the centers of the knives 3.

The width d of the groove 8 is less than the width S of the grip 8 of the knife 3 by the amount of overlap of the cutter blades located in the adjacent cutting planes.

The cutting edge of the shear knife 6 is formed by the intersection of the edges of the fender plate 5 with the surface of the casing 4.

The tool works as follows.

Cutter 2, when the gun is moving, mills the soil along with the shrub and wood inclusions, which by means of the grooves 8 is attached to a position oriented along the longitudinal axis of the tool. Due to the plates 7 and the shape of the cutting edge of the shear knife 6, the shrub trunks are held in a fixed position at the time of cutting them with the knives 3, eliminating the possibility of transverse sliding of the trunks. As a result, the shredder is completely crushed.
