Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery industry and can be used for continuous milling of soils. The purpose of the invention is to improve the quality of processing of smoked land by increasing the degree of shredding of woody vegetation. The shredding mill contains a frame 1 with slits 2, on which a driving tool is mounted at an angle to the direction of movement. The drive working body is made in the form of a shaft 4 with racks 5. The main cutting elements are fixed in the front part of each rack 5, and additional 7, 8 are fixed in the rear part. The latter can be made either by means of a worm or L-shaped. The cutting elements 7, 8 can be installed at different parts of the rack 5, in particular at its ends. The working edges of the elements 7, 8 protrude beyond the lateral surface of the rack 5. In the slots x 2 of the frame 1, the counter-cutting elements 9, 10, 11 are installed, constituting the cutting pairs with the additional elements 7, 8. The number of additional cutting elements and their relative position on The racks in the process of interacting with the anti-cutting elements during the operation of the cutter provide the required degree of grinding of woody vegetation. 2 hp f-ly, 4 ill. § SL

The invention relates to agricultural machinery industry and can be used for complete milling: gyrus, as well as a brush cutter.

The purpose of the invention is to improve the quality of processing of smoky land by increasing the shallow wall of shredding woody vegetation.

FIG. 1 shows a soil tillage and cutter, top view; in fig. 2 - the same, side view; in fig. 3 - a stand with additional rezhim.imi elements in the form of straight knives with the trajectories of their movement; . in fig. 4 - the same, with additional cutting elements in the form of L-shaped knives.

The soil is cultivated, and the milling cutter contains frame 1 with slots 2. On the frame, through the bearing supports 3, there is installed a drive unit in the form of a shaft 4 with radially curved struts 5. The shaft 4 with the supports 5 is set at an angle to the direction of movement of the mill . The angle may be, for example, 55 °. On the uprights 5, in the front part of them, the main knives 6 are installed, and in the rear part - the additional undercutting 7 and the chopping 8 knives. On the frame 1 with an outlet in the slot 2, there are mounted counter-cutting elements 9-11, which can be moved, for example, by means of grooves in order to provide optimal gaps with the corresponding main 6 and additional 7 and 8 knives. Behind the working body, a separating comb 12 and a smoothing plate 13 are installed on the frame 1, which can be moved in height.

Claims (3)

1. A soil tillage cutter containing a frame with slots and mounted on the frame at an angle to the direction of the moving blades 6 can be made 35 driving the drive body in the form of a shaft 40 45 both whole and compound. Additional trimming knives 7 are located at the ends of the uprights 5 and can be made straight or L-shaped. In the case of straight knives, the undercutting elements 7 are mounted at the ends of the uprights 5 with outreach relative to their lateral dimensions 1), and their cutting edges do not extend beyond the projection of the circle of rotation of the main blades 6 to the plane perpendicular to the direction of movement. In the case of construction in the form of L-shaped knives, the undercutting elements 7 are mounted at the ends of the uprights 5 with departure relative to their lateral surface, and their cutting edges extend beyond the projection of the circle of rotation of the main knives 6 on the 1 plane, perpendicular to the direction of movement. Additional chopping knives 8 are placed between the knives 7 and the shaft 4. The number of knives 8 and their placement on the uprights 5 determine the necessary degree of 50 with stakes, in the front part of which the main cutting elements are fixed, and the working edges of the latter are located perpendicular to the shaft axis, characterized in that, in order to improve the quality of tillage by increasing the degree of its grinding, each rack is equipped with at least one the back of the rack additional cutting element with a working edge protruding beyond the lateral surface of the rack. 2. A milling cutter according to claim 1, characterized in that, in order to improve the quality of processing of the exhausted lands, the frame is provided with counter-elements installed in its slots forming cutting pairs with the main and additional cutting elements of the working member. 3. A milling cutter according to claim 1, characterized in that the additional cutting element is mounted at the end of the stand and is L-shaped. five 0 0 5 0 shredding of woody vegetation and its fractional composition. Knives 7 and 8 can also be made together with the main knives, 6. Night-processing cutter works as follows. In the process of moving the gun, frame 1 slides onto pre-felled woody vegetation at a speed of V, and a driving working body rotating at a speed of lO with main knives produces milling by separating chips from the soil and wood. The cutting is carried out with the participation of the shear elements 9. The additional knives 7 cut the chips formed by the knives 6, while the wood inclusions are also cut by the conflicting elements 10. With the additional cutting elements 7 in the form of straight knives, the milling is done to a depth less than the milling depth H, determined by the deepening of the main knives b, since the chips are not cut at the very base, but above it by the amount hB when the knives are made 7 L-shaped, the milling depth H is saved to the depth of cutting knives 6. Grinding knives 8 cut the cut chips to the required size with trimming wood inclusions with opposing elements 11. Invention Formula 1. A tillage cutter containing a frame with slots and mounted on the frame at an angle to the direction of movement of the drive working body in the form of a shaft 0 five five 0 with stakes, in the front part of which the main cutting elements are fixed, and the working edges of the latter are located perpendicular to the shaft axis, characterized in that, in order to improve the quality of tillage by increasing the degree of its grinding, each rack is equipped with at least one the back of the rack additional cutting element with a working edge protruding beyond the lateral surface of the rack. 2. A milling cutter according to claim 1, characterized in that, in order to improve the quality of processing of the exhausted lands, the frame is provided with counter-elements installed in its slots forming cutting pairs with the main and additional cutting elements of the working member. 3. A milling cutter according to claim 1, characterized in that the additional cutting element is mounted at the end of the stand and is L-shaped. i5 (.2 srig.z X / Fivl
