Abstract

The invention relates to the woodworking industry. The purpose of the invention is to reduce operating costs. The centrifugal wood-shaving machine includes a housing with inlet 2 and outlet 3 hatches. A drive impeller 4 with blades 5 and a grinding body 6 are installed inside the casing. On the impeller 4 and shaft 7, blades 8 are additionally mounted, on which the blows 9 are mounted. During operation, the impeller rotation 4 is driven. Lump waste is fed through the inlet hatch 2. Initially waste the blades are broken by 8s bilami 9 and by centrifugal forces when the impeller 4 rotates, they are thrown to the grinding body 6. The blades 5 of the impeller 4 break wood particles falling under them and drag them through the holes in the grinding org 6. The resulting chips are not removed from the machine through the outlet hatch 3. 4-yl. (L S h | N O 00 O 4

Description

The invention relates to the woodworking industry, namely, equipment for grinding wood materials in the production of chipboard.

The purpose of the invention is to reduce operating costs.

FIG. 1 shows a machine, a general view; in fig. 2 — node I in FIG. one; in fig. 3 - machine, side view; in fig. 4 - vib B in FIG. 3

The centrifugal wood-shaving machine includes a housing 1 with an inlet 2 and an exit 3 hatches, inside which are mounted a drive impeller 4 with blades 5 and a chopping body 6. On the impeller 4 and shaft 7 are additionally radially mounted equally spaced one relative to the other blade 8. The blades 9 are fastened to the cutting surfaces of the blades 8 on the side of the entrance hatch 2. An anvil box 10 is placed on the body 1 with an offset from the center.

The machine works as follows.

The rotational drive of the impeller 4 is turned on. The lump wood waste fed for processing through the entrance hatch 2 of the housing 1 is initially broken by additional blades 8 and by centrifugal forces during the rotation of the impeller 4 are thrown to the grinding body 6.

The blades 5 of the impeller 4 break down the wood particles falling under them and

pulling them through the holes in the grinding body 6. The chips produced are removed from the machine body 1 through the exit hole and fed into the process stream, after which the cycle is repeated.

The use of the proposed machine in the conditions of industrial production of chipboard provides, by combining the operations of primary and subsequent grinding of wood particles, a significant reduction in operating costs, while eliminating the use of additional vehicles and equipment for storing an interoperable stock of chips.

Form of the invention The centrifugal wood-shaving machine, which includes a housing with inlet and outlet hatches, a shaft, an impeller with blades, an actuator, so that it is possible to reduce operating costs / the impeller is additionally mounted blades, which are made in the form of trapezium, with smaller bases of the trapezium mounted on the shaft, blades of the impeller are located on large bases, and a counterstrike is fixed on the inclined surfaces of the additional blades, It is located at an angle to the axis of symmetry of the entrance hatch.
