Specific embodiment

It is specific embodiment of the utility model below, and with reference to attached drawing, the technical solution of the utility model is made into one The description of step, but the utility model is not limited to these embodiments.

A kind of pulverizer, as shown in Figure 1, this pulverizer is used to crush various solid materials, this pulverizer Including：Shell 100, pulverization cylinder 200, sieve plate 300, shredder assemblies and wind suction part 500.

The upper and bottom section of 100 inner wall of shell has connecting rod, for connecting fixed pulverization cylinder 200.Cover top portion With import 130, for introducing in the material to pulverization cylinder 200 for needing to crush.

Shredder assemblies are installed, shredder assemblies include motor 410, the spiral shell of axis connection is exported with motor 410 in pulverization cylinder 200 Revolve crushing knife 420 and the hammer leaf 430 on 200 barrel of pulverization cylinder.

The width of spiral crushing knife 420 is gradually broadening from top to bottom, and the radius of each layer of blade gradually increases from top to bottom, When the output rotating speed of spiral crushing knife 420 is certain, the linear velocity on the blade of each layer of blade is different so that spiral crushes Knife 420 has different crushing dynamics from top to bottom, and classification grinding to crush evenly.

The middle section of 420 blade of spiral crushing knife is recessed inwardly, and upper and lower two edge mouth forms new edge, on the one hand So that 420 each layer of spiral crushing knife has two layers of blade, dynamics bigger is crushed, on the other hand, during due to crushing, material and spiral shell The shock revolved between crushing knife is largely eccentric impact, the side edge at material key strike blade both ends, therefore new spill knife Sword structure can slow down the abrasion of blade, meanwhile, if carrying out strength optimization processing on its cutting edge, its powder can be further increased Broken dynamics slows down its degree of wear.

On the knife face of spiral crushing knife 420 there are several projection pieces 421, when material has just enter into pulverization cylinder 200, can hit It hits on projection piece 421, to increase crushing dynamics.

Under the leading of spiral crushing knife 420, material carries out the rotary motion of high speed, and formation expects ring, expects ring from level to level Outermost layer is often large granular materials.There is hammer leaf 430 on 200 barrel of pulverization cylinder, large granular materials are in high-speed rotation In be substantially carried out hitting between hammer leaf 430 and crush, be mostly similarly, between material and hammer leaf 430 it is eccentric hit, hammer leaf 430 End face is spill, can slow down the abrasion of hammer leaf 430.Meanwhile side to 200 inner wall of pulverization cylinder and hammer leaf 430 and end face into Row plucking or embossing processing so that there is certain rough surface on the side and end face of 200 inner wall of pulverization cylinder and hammer leaf 430 Degree increases the friction between 200 barrel of material and pulverization cylinder, hammer leaf 430, to promote crushing effect.

Material after shredder assemblies crush is sifted out by the sieve plate 300 of 200 bottom of pulverization cylinder, pulverization cylinder 200 and sieve It is connected between plate 300 by being connected pawl 310, through-hole is offered in the lower part of 200 barrel of pulverization cylinder, linking pawl 310 is by two Claw and an end are formed, and after two claws are each passed through through-hole, sieve plate 300 is connected between two pawls, is connected the end of pawl 310 It is connected on the sliding part 110 of 100 inner wall of shell.The diameter of through-hole should be greater than passing through the part of through-hole in linking 310 claw of pawl Width and height so that linking pawl 310 can be free to slide in through-holes under the drive of sliding part 110 so that sieve plate 300 can vibrate to achieve the purpose that prevent sieve pore blockade.Meanwhile the sieve pore edge on sieve plate 300 is turned over downwards and convexes to form Annular blade 320 so that be blocked in the material at sieve pore by cutting rubbing, further achieve the purpose that prevent sieve pore blockade. Plucking or embossing processing are carried out in the upper surface of sieve plate 300, certain surface roughness is made it have, increases material and sieve plate Friction between 300, to promote crushing effect.

In the lower section of sieve plate 300, there is the wind suction part 500 mounted on 100 bottom of shell so that material is under high speed rotation Can close to and pass through sieve plate 300.

100 bottom surface of shell is spherical arc shape, and arc minimum point has outlet 120, for exporting the material after crushing.

The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute Described specific embodiment can be done various modifications or additions or using similar by belonging to those skilled in the art Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
