Description

The invention relates to earthmoving machinery, namely, working bodies for the treatment of land with milling.

The purpose of the invention is to increase the productivity and quality of ground grinding.

FIG. 1 shows the working body of the general view; FIG. 2 is a section A-A and FIG. one; in fig. 3 shows the layout of the bosses on the drum; in fig. 4 is a view B in FIG. one; in fig. 5, view B in FIG. I.

The milling tool includes a frame 1 on which a baffle plate 2 with a knife 3 is installed, cut-out cutter A, consisting of a body made in the form of a drum with welded lugs 5 and 6 of different sysyo.

The hollows along the length of the shear knife 2 are made identical in length and are installed with a pitch t, and the length of the protrusions is less than the length; hollows

B. in each row located in the section; perpendicular to the axis of the milling cutter, alternately along the length of the milling cutter 4 are high 5 and low 6 bosses, in which the cutting elements 7 are mounted. These rows are at equal distance from each other.

On the frame 1 in its upper part there is an additional cutting knife made of plate 8 fixed to the frame and attached to it along the entire length of the cutter at equal distances from each other by plates 9 with knives 10, and their width and distance between them ( depressions) are respectively equal to the length of depressions and ridges on the opposing knife 3.

Due to the fact that the length of the protrusions on the shear blades is less than the length of the valleys and the pitch t is less than the width of the two cutting elements, it is possible to use knives of the same width that overlap each other during cutting.

The cutting elements secured to the low lugs 6 are arranged to be placed against the protrusions formed by the plates 9 with the knives 10 of an additional shear knife, the length of the cutting edge of the element 7 being longer than the length of the protrusion. And the cutting elements attached to the high bosses are installed with the possibility of placing an additional shear knife in the valleys.

When the milling machine operates, the rotation from the tractor's power take-off shaft is transmitted through the transmission to the side reduction gear and then to the cutter reduction gear. From the cutter reducer, the rotation is transmitted to the cutter 4 via a shaft.

With the forward movement of the machine, the woody vegetation trunks are raised by the front blade, the caterpillars and the tractor tray and fall under the fender plate 2, which

presses them against the surface of the soil. A rotary milling cutter 4 with cutting elements 7 crushes the growing and buried wood together with the soil and,. throws the mass on separaruntsy

grates (not shown), through which the soil passes freely, and the wood fractions are discarded at the bottom of the processing strip and instilled. Rear mounted press

the drum produces leveling and compaction of the treated surface.

When milling, wood vegetation is first ground when

the passage of the cutter elements through the shearing knife 3 and is additionally ground when passing through the additional shearing knife. At the same time, the cutting elements mounted on high bobshka 6, in addition to additional grinding of wood, clear the space between the plates: 9 from sticking mass.
