Abstract
The utility model discloses a blade group mechanism for a pulverizer, which relates to the technical field of pulverizing machinery, and comprises a cutter shaft, a cutter head and a cutter head isolating piece, wherein the cutter head and the cutter head isolating piece are alternately connected in series with the cutter shaft, the cross section of the cutter shaft is in a cross shape and is matched with the mesopores of the cutter head and the cutter head isolating piece; the thickness of the cutter head isolating piece is not less than that of the cutter head; 2-4 cutting edges extend out of the cutter head along the radial direction, the rear part of each cutting edge, namely a cutter back, is cut into the outer edge of the cutter head in a curve, the thickness of each cutting edge is smaller than that of the cutter head, and the thickness of the cutter back is gradually thickened from the cutting edge until the thickness of the cutter back is equal to that of the cutter head; and a row of artificial diamonds are embedded in the cutting edge along the radial direction of the cutter head. The utility model can effectively improve the crushing effect of the blade group for crushing hard objects through the artificial diamond on the surface of the cutting edge; the blade is gradually thickened, so that the crushed material is torn, and the crushing resistance is reduced; the cross section of the cross-shaped cutter shaft is beneficial to power transmission, and the abrasion to the cutter shaft and the central hole of the cutter head is reduced.
Description
Technical Field
The utility model belongs to the technical field of rubbing crusher technique and specifically relates to a blade group mechanism for rubbing crusher.
Background
The crusher is a common mechanical device in production and life, and the blade assembly is a core component of the crusher. When the crusher crushes hard materials, the blade assembly is seriously abraded, and the crushing effect is not good.
SUMMERY OF THE UTILITY MODEL
In order to overcome the above-mentioned defect that exists among the prior art, the utility model provides a blade group mechanism for rubbing crusher.
The utility model provides a technical scheme that its technical problem adopted is: a blade group mechanism for a pulverizer comprises a cutter shaft, a cutter head and cutter head isolating pieces, wherein the cutter head and the cutter head isolating pieces are alternately connected in series with the cutter shaft to form blade groups, and the cutter head isolating pieces between two adjacent blade groups are mutually staggered; the cross section of the cutter shaft is in a cross-flower shape and is matched with the middle holes of the cutter head and the cutter head spacer; the thickness of the cutter head isolating piece is not less than that of the cutter head; 2-4 cutting edges extend out of the cutter head along the radial direction, the rear part of each cutting edge, namely a back of each cutting edge, is cut into the outer edge of the cutter head in a curve mode, the thickness of each cutting edge is smaller than that of the cutter head, the thickness of each back of each cutting edge is gradually thickened from each cutting edge until the thickness of each back of each cutting edge is equal to that of the cutter head, and the cutting edges of two adjacent blade groups are; and a row of artificial diamonds are embedded in the cutting edge along the radial direction of the cutter head.
The blade set mechanism for the crusher is characterized in that the surface of the blade back is provided with transverse saw teeth.
The utility model has the advantages that:
1. in the structure of the utility model, the artificial diamond on the surface of the cutting edge can effectively improve the crushing effect of the blade set on crushing hard objects;
2. the utility model has the advantages that the blade is gradually thickened, which plays a tearing role to the crushed material, reduces the crushing resistance and improves the crushing effect;
3. the utility model discloses the arbor cross section of cross flower shape is favorable to power conduction in the structure to the wearing and tearing to arbor and blade disc mesopore have been slowed down.
