Description

A kind of hammer crusher
Technical field
The present invention relates to a kind of hammer crushers, usually in the row such as stalk, straw, feed, grain, food, chemical industry, medical treatment It is used in industry.
Background technique
Such pulverizer usually by feeding hole of pulverizer (1), hammer leaf (2), rotor (3), door (4), pressure screen frame) 5), motor (6), pulverizer discharge port (7), body (8), sieve (9) etc. form.When work, rotor (3) are driven by motor (6), make rotor (3) on hammer leaf (2) rotation, material from feed inlet (1) come in after by hammer leaf (2) constantly crush, the powder of smashed qualification Sieve pore across sieve (9) is discharged from pulverizer discharge port (7).
This kind of pulverizer has the following problems: can not crush to the material of high-moisture, high microsteping, high grease, material is easy Block sieve.
Summary of the invention
It is an object of the present invention to provide a kind of hammer crushers, it is desirable that pulverizer can be to high-moisture, high microsteping, high grease Material is crushed, and material does not block sieve.
Key of the invention is as follows using a kind of its structure of newly-designed hammer crusher:
A kind of hammer crusher, by feed inlet (1), hammer leaf (2), rotor (3), door (4), pressure screen frame (5), motor (6), powder The composition such as broken machine discharge port (7), body (8), sieve (9).It is characterized in that the hammer leaf is a kind of claw hammer leaf, by common One end of the hammer leaf parent (12) of steel making, hammer leaf is equipped with pin hole (13), and the other end of hammer leaf is crushed work end face (14), In Operative end surface (14) is formed using wear-resistant material hardfacings such as tungsten carbides, and whole surface makees comentation hardening processing, hammer leaf parent (12) Front end is welded with scraping blade (15), scraping blade (15) and hammer leaf parent (12) vertical welding, and the two front end is aligned, in scraping blade (15) leading edge Place, the equal heap of upper and lower surface are welded with wear-resistant material (16), the angle on resurfacing welding material (16) slope and hammer leaf parent (12) surfaceIn Between 30-60 degree, the height of built-up welding is 1-2 times of thickness of hammer leaf parent (2), and a pulverizer can fill part or fill whole Claw hammer leaf.
Using the pulverizer of above-mentioned claw hammer leaf, hammer leaf parent (12) continues to keep the strike crushing function to material, scrapes Piece (15) can carry out the cleaning of large area to crusher sifting surface, and scraping blade (15) heap is welded with slope and the compass screen surface of wear-resistant material (16) There is (90 degree of angle), high-moisture, high microsteping, high-lipid material can be squeezed out to sieve pore, wear-resistant material (16) reverse side There is a material recirculating zone, allows qualified material and sieve pore again with a touch opportunity, it is the high-moisture of such pulverizer, high fine Dimension, high grease block up sieve problem and are solved.
The present invention can also be equipped with the pulverizer (Fig. 3) for determining hammer using a kind of, in this way, when material is moved in sieve surface lateral When dynamic, hammering and shear action are generated with the hammer of determining of side.A kind of pulverizer (Fig. 4) of sieve vibration can also be loaded onto, it is special Sign, which is to press below screen frame (5), is equipped with vibrating motor (11), which is connected with pressure screen frame (unit), passes through the vibration isolation such as spring Device make to press screen frame (unit) and sieve (9) can Independent Vibration, crushing effect is more preferably.
