SU1211046A1 - Chipper for processing lump waste - Google Patents

Description

The invention relates to the woodworking industry, in particular to wood shredding equipment.

The purpose of the invention is to improve the quality of Dj.enb and reduce energy consumption.

FIG. presented machine, general view, cut; figure 2 - section aa in figure 1; on fig.Z - section B - B in figure 2; figure 4 - section b - b in figure 2; figure 5 - counter knife mange.

On housing 1 in shaft 2, shaft 3 is mounted on which the blade disk 4 is fixed. In the middle, there are annular grooves 5 in which the cutting knives 6 are laid out. The cutting edge of the knives 6 is set flush with the working surface of the blade disk 4, and the cutting blades the knives 7 are mounted in such a way that their cutting edge protrudes above the working surface of the noA-A

chewing disk 4. To the latter are attached blades 8 for ejection of chips. The blade disk 4 is closed by a casing 9 with a loading cartridge 10 and a counter-knife 11, made with protrusions and grooves.mm.

The chipper for processing lump waste works as follows.

The blade disk 4 is driven into rotation. The piece waste is fed through the loading cartridge 10 into the zone of action of the cutting knives 6 and 7 and the counter knife 11, where they are ground into chips. In this case, cutting of lumpy waste into chips using cutting knives 6 is carried out on protrusions, and cutting knives 7 is in the grooves of the counter-knife 11. The length of the received chips depends on the outflow of cutting knives 6 and 7. The chips are diverted to the process flow, after which the repeat cycle yut.
