The specific operation process comprises the following steps:

and (3) coarse filtration process: will treat from feed inlet 2 and smash the thing and place on coarse filtration board 3, then start actuating mechanism, actuating mechanism orders about connecting plate 15 to waiting to smash the thing and feeds, make cutting knife 16 treat and smash the thing and cut, the realization is treated the coarse crushing of smashing the thing, treat after the cutting and smash the thing if satisfy coarse filtration board 3's filtration particle size, can drop down, be greater than coarse filtration board 3's the filtration particle size treat that the thing is still stayed on coarse filtration board 3, cut repeatedly through cutting knife 16.

Simultaneously cutting knife 16 is down cut when treating the crushing thing, cutting knife 16 can push down thick filter plate 3 earlier, thick filter plate 3 linkage connecting rod 18 extrudees the spring 17 that is located connecting rod 18 below, and stretch the spring 17 of connecting rod 18 top, extrude to the limit until spring 17, or when the junction of connecting rod 18 and thick filter plate 3 offsets with the bottom edge of vertical groove, thick filter plate 3 receives the hindrance, can't continue downstream, the downstream of cutting knife 16 and the cutting treat the crushing thing this moment, the motion path length of setting up crank slider mechanism according to the structure of device, make cutting knife 16 just touch with thick filter plate 3, avoid cutting knife 16 to cause the harm to thick filter plate 3. After the cutting is finished, the slider-crank mechanism drives the cutting knife 16 to withdraw rapidly, and the cutting knife 16 retracts rapidly without influencing the bouncing of the coarse filter plate 3.

At this moment, the coarse filter plate 3 loses the extrusion acting force of the cutting knife 16 on the coarse filter plate, the spring 17 below and above the connecting rod 18 applies the acting force of upward movement reset to the connecting rod 18, the connecting rod 18 drives the coarse filter plate 3 to bounce, and the spring 17 has inertia, so that the coarse filter plate 3 bounces back and forth, thereby the coarse filter plate 3 vibrates in the bouncing process, the object to be crushed on the coarse filter plate 3 drops downwards, and the object to be crushed is prevented from blocking the coarse filter plate 3.

Fine filtration process: according to the demand of the user for the particles with different particle sizes, the swing angle of the partition plate 11 is adjusted, so that the size of the receiving surface of the control plate I and the control plate II 13 for receiving the falling particles of the coarse filter plate 3 is adjusted. Pulling pull rod 10, pull rod 10 drive the slider and remove in the spout, and the slider realizes dragging, pulling to 11 tops of baffle, makes baffle 11 and horizontal position form different contained angles, and the horizontal position of spout restriction slider in addition to make baffle 11 stretch out and draw back along with swing angle is automatic, with buckle and draw-in groove joint on the pull rod 10 again, realize the location to baffle 11.

And the thing of waiting to smash that drops on board one slides down to diaphragm 6 along hang plate 5 on, the starter motor, and motor control dwang 4 rotates, then the synchronous rotation of the helical blade on the dwang 4, and the helical blade is to waiting to smash the thing cutting on diaphragm 6, realizes treating further the smashing of smashing the thing, obtains the granule that the particle diameter is littleer. These less particles of particle size fall to waste material filter 7 from the fine filter on, waste material filter 7 filters the waste material granule and the dust of undersize, and the waste material falls to collecting the intracavity, and other required particles are then from the automatic sliding of waste material filter 7 to discharge gate 14. And the material to be crushed falling on the second plate 13 can be directly taken out from the second discharge hole 12 to obtain particles with thicker particle size.

And (3) a dust removal process: the output of piston rod and slider-crank mechanism reciprocates in step, and according to the intercommunication position of piston cylinder and box 1, when realizing cutting knife 16 downstream, the air inlet at piston cylinder top switches on, breathe in to the outside in the piston cylinder, and when cutting knife 16 cuts and finishes and upward movement, the piston rod upwards moves thereupon and drives piston plate upward movement, the piston plate extrudees the gas in the piston cylinder to box 1 in, the check valve in the trachea 9 switches on, gas gets into the dust that box 1 will cut the production from trachea 9 and blows down, make the dust move down to collect the intracavity, the clearance of unifying again, avoid the dust adhesion on equipment, influence equipment normal operating.

The above description is only an example of the present invention, and the common general knowledge of the known specific structures and characteristics of the embodiments is not described herein. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
