CN201316659Y - Extrusion shearing rotary blade for crushers - Google Patents

Abstract

An extrusion shearing rotary blade for crushers includes two parts, i.e. a blade body and a clinched cutting edge, wherein the clinched cutting edge is arranged in the blade body; and the included angle between the root of the cutting edge and the blade body is larger than 90 degrees. The utility model has the advantages that the cutting edge can be easily disassembled and replaced, thereby reducing the waste of the overall replacement of a worn rotary blade, as well as saving the material cost; and the cutting edge is trapezium-shaped, so that acute angles do not exist between the cutting edge and the blade, thereby avoiding the phenomenon of 'tooth clogging', and improving the crushing efficiency.

Description

The compression shearing type crusher rotating blade

Technical field

The utility model relates to the compression shearing type crusher that crushing sponge titanium is used, particularly the rotating blade of compression shearing type crusher.

Background technology

Titanium sponge adopts conventional breaker because hardness is higher, broken difficulty, efficient is not high, and easily make product jaundice and go bad, for this reason, compression shearing type crusher was just invented by Zunyi Titanium Industry Co. Ltd. in 2005, and obtained patent for invention (patent No. 200510003179.7), but this compression shearing type crusher rotating blade is an integral knife blade, and blade is born broken task, serious wear, after blade is not sharp, the full wafer rotating blade have to be changed.

And the angle between blade root and the lamellar body＜90 ° are caused " getting stuck between the teeth " phenomenon easily, and promptly a large amount of chips is extruded and is deposited in the blade place, has reduced crushing efficiency, makes cleaning very difficult.

The utility model content

The purpose of this utility model is to overcome deficiency of the prior art, thereby a kind of rotating blade is provided.

For achieving the above object, the technical solution adopted in the utility model is:

The compression shearing type crusher rotating blade comprises that cutter blade and pincers go into blade two parts, and described pincers are gone into blade and are located in the cutter blade, the angle between blade root and the cutter blade＞90 °.

Adopt the beneficial effect of technique scheme to be:

But 1, blade easy removal and replacing have reduced the waste of rotating blade wearing and tearing back integral replacing, have saved Master Cost.

2, blade is trapezoidal, and " getting stuck between the teeth " phenomenon has been avoided in the angle between blade and the blade＞90 °, has improved crushing efficiency.

Description of drawings

Fig. 1 is a rotating blade of the prior art.

Fig. 2 is a rotating blade structural representation of the present utility model;

Among the figure: 1-cutter blade, 2-clamp into blade.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail:

The compression shearing type crusher rotating blade comprises that cutter blade 1 and pincers go into blade 2 two parts, and described pincers are gone into blade 2 and are located in the cutter blade 1, angle＞90 between blade 2 roots and the cutter blade 1 °.This rotating blade forms shearing force, crushing sponge titanium by a rotating shaft driven rotary with fixed blade.

Claims (1)

1, compression shearing type crusher rotating blade, it is characterized in that: described rotating blade is divided into cutter blade (1) and pincers are gone into blade (2) two parts, pincers are gone into blade (2) and are located in the cutter blade (1), angle＞90 between blade (2) root and the cutter blade (1) °.
