Abstract

Usage: in the woodworking industry, in particular in equipment for shredding wood in the production of chipboard. SUMMARY OF THE INVENTION: The additional horizontal loading opening and the charging funnel are separated by means of a lid that is hingedly attached to the housing at the point of their merging. The lid of the additional loading horizontal opening serves as a pressure device for the crushed lumpy waste in the logging area for chips and serves to orient the wood particles when chips are used as a raw material. 2 Il.

Description

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

A device for making chips is known, comprising a housing with a disk-type cutting mechanism mounted in it with a shaft, on which the rotating rotor and an impeller are mounted in the opposite direction, a feeding mechanism and an additional nozzle.

A rotary-type machine for grinding lumpy waste is known, consisting of a housing, a feeder, a special rotor, an anvil, and a screen sieve.

However, these devices allow only lumpy wood waste to be recycled.

The purpose of the invention is the expansion of technological capabilities in the processing of various wastes.

The goal is achieved by the fact that in a crusher comprising a housing with a feed hopper, a two-section fixed drum, a sectional cylindrical rotor, a feed mechanism, an actuator, the feed funnel is equipped with a vertical and horizontal loading no holes.

Figure 1 shows the scheme of the crusher, side view; figure 2 - section aa in figure 1.

The proposed crusher for the manufacture of chips from chips and lump wood waste consists of a housing 1 with a feed funnel 2, which has a vertical feed hole 3 for chips and small waste and a horizontal feed hole 4 for lump wood waste, and a discharge port 5. Vertical 3 and horizontal The 4 loading openings are separated by a lid 19, which is fixed in the body of the loading funnel 2 by means of

the hinge 20 in place of the holes. Inside the housing 1, a two-piece stationary drum b is installed, consisting of a sieve 7 and an annular gear grinder 8. The grinder 8 consists of several rings installed with the possibility of their mutual rotation. Rings in the circumferential direction can be made composite. The inclination of the teeth of the ftaVovfEiiax shredder 8 may be different. In kopriyce 1, a cylindrical rotor 10 with grinding elements, consisting of sections 11, 12 and 13, is mounted on the shaft 9 inside the drum b in two bearings. Section 11 is equipped with knives 14, and sections 12 and 13 are grinding plates 15. Knives 14 and grinding The plates 15 of the section 12 are set at an angle to the axis of the shaft 9 and with the working surface facing the screen 7 in the direction of rotation of the shaft.

The piece waste for grinding is delivered to the crusher by means of conveyor 16 and rollers 17. To support the waste during the cutting process, a counterbag 18 is provided, which is fixed to the hole 4 in the slab.

Crusher for the manufacture of chips from chips and lump wood waste works as follows.

The piece of wood waste by the conveyor 16 and the rollers 17 through the horizontal loading opening 4, lifting the lid 19, is fed to the counter knife 18. The cutting process is carried out by the rotor blades 14 of the rotor 10. Next, the chopped chips fall into the grinding zone formed by the knives 14 and the teeth (lugs) of the ring shredder 8. Angled knives 14 move the material to be ground along a circular arc and forward, as a result of which the material moves along a helix. The material, moving forward, flies off the knife 14 of section 11, immediately grinding plates 15 of section 12 pick it up and drag it along a helical line along an annular gear grinder 8 of drum 6.

Such a complex movement ensures complete grinding of the material into chips. The tilt of the teeth contributes to the retention of large particles in the grinding zone, and the fine particles are carried by air flow to the sieves 7, which eliminates overgrinding of individual particles. By reciprocating the rings of the gear grinder 8, as well as by shifting the rings in the axial direction, the degree of grinding is regulated, as the time spent for particles in the grinding zone is reduced or increased.

Then the grinding plates 15 of the last section 13 pick up the material

dragging it through the screens 7, grind off. The grinding of the material is carried out to the size of the sieve cells, after which it is removed through the sieve 7 cells in the form of fibrous, homogeneous wood particles into the process stream. Then the cycle is repeated.

In the case of using chips or other small particles as a raw material, the material is fed to the crusher through a vertical feed opening 3. In this case

the cover 19 is in the lower position. The hinged attachment of the lid 19 allows for the simultaneous processing of chips and lumpy waste.
