Description

The invention relates to agriculture and forestry and is intended for tillage on clearings for agricultural use or planting of forest crops. L .-- The purpose of the invention is the improvement of the productivity and quality of tillage,.

FIG. 1 shows a milling machine, side view; 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one. ,

The machine contains a frame 1, transmis-. This 2, milling drum 3 with disc-shaped knives 4, located on the outer surface of drum 3, flat blades 5 of curvilinear shape mounted on the drum ends, with one-sided sharpening, baffle plate 6, with fixed counter-cutting knife 7 and leashes 8, connecting A hinge plate with a shaft 9 of drum 3, a shock absorber 10 connecting the baffle plate 6 with the frame 1 is mounted. On the leads 8, adjoining the baffle plate 6, on the inside there are cutter knives 11 that interact (form a cutting pair) with the knives 5 . Between the knife and otse- Katel E-11 on leads 8 are mounted reflectors 12 formed in vid§ sharpening plates and set at an acute angle end of the drum 3. When operating in the transport position and the machine is supported on the Stake / I- / 1

ca 13. The transfer to the transport position is carried out by hydraulic cylinders 14. The machine operates as follows. At the beginning of the working process, the milling drum 3 is rotated from the tractor power take-off shaft 5 through the transmission 2 and the support wheels 13 are lifted by means of hydraulic cylinders 14. The milling drum 3 is knifed 4

10 and 5 crushes (loosen) process-. This material, while the baffle plate 6 with shock absorbers 10, keeps the wood inclusions from moving, and the disc blades 4, in conjunction with the counter knife, 7, grind the wood inclusions located mainly along the axis of the machine.

When hit under the knives 4, wood inclusions located across the machine axes are captured by the knives 5 and interacting with the cutter knives 11 cut them, thereby eliminating clogging

25 between the baffle plate 6 and the drum 3 with large logging residues.

The oval shape of the knives 5 ensures cutting with sliding, which reduces the cutting force required, and

3Q in the case of hit of wood inclusions of large diameter contributes to their discarding.
