Abstract

Inventia se refera la un organ de taiere pentru combine miniere, în special pentru combine miniere de abataj folosite în industria carbonifera. Organul de taiere este format dintr-o elice prevazuta spre frontul de abataj cu o portiune cu pas constant cu o sectiune dreptunghiulara în plan radial, portiunea fiind extinsa pe cel mult 1/2 din lungimea elicei, spre combina miniera elicea este prevazuta cu o alta portiune cu pas variabil radial axial. Portiunea dinspre combina are în plane radiale sectiuni de forma curba.The invention relates to a cutting tool for mining combines, especially for coal mining combines used in the carboniferous industry. The cutter consists of a propeller provided on the cutting edge with a constant pitch with a rectangular cross-section in the radial plane, the portion being extended to no more than 1/2 of the length of the propeller, to combine the mining propeller is provided with another radially axial variable pitch portion. The portion from the combine has in radial planes sections of curved shape.
