The material is put into a crushing and grinding cylinder 7 through a feed port 3, a crushing and grinding motor 1 and a vibrating motor 9-16 are started at the same time, the crushing and grinding motor 1 drives a crushing and grinding hammer 6 to rotate and hammer up and down through a connecting shaft 5, the material is firstly cut and crushed in a cutting and crushing area 14, the material is cut and crushed mainly by the rotating action of a cutting knife body 9-2 on the crushing and grinding hammer 6, particularly the material with large particle size and fibrous substances, the material can be crushed more ideally through cutting, the subsequent grinding is convenient, the hammering action of the crushing and grinding hammer 6 in the area does not work on the material, the cut and crushed material flows into a crushing and grinding area 15, the entering material is mutually extruded and ground on a crushing and grinding surface 6-4 on the crushing and grinding hammer 6 and a crushing and grinding surface 7-1 on the crushing and grinding cylinder 7, the materials are crushed and coarsely ground again, the coarsely ground materials continuously flow downwards into a fine grinding area 16, the materials are continuously extruded and ground in the area through a crushing grinding surface 6-4 on a crushing grinding hammer 6 and a crushing fine grinding surface 7-2 on a crushing grinding cylinder 7, the materials are finely ground, the gap of the fine grinding area 16 is preset in advance by adjusting the position of the crushing grinding hammer 6 according to the requirement of the grinding particle size of the materials, the materials passing through the fine grinding area 16 flow downwards into a filter assembly 9 through a flow guide area 17 under the spiral pushing action of a material pushing body 6-5, and the material pushing body 6-5 and the flow guide surface 7-3 can still perform fine grinding on the finely ground materials again while passing through the flow guide area 17.
The vibrating motors 9-16 convert the periodic rotary motion of the vibrating bodies 9-11 into periodic annular sieving motion of the vibrating bodies 9-11 along the horizontal direction, the periodic annular sieving motion effect of the sieve meshes 9-8 in the horizontal direction is better, materials after being crushed and ground flow into the sieve meshes 9-8 through the flow guide areas 17, the materials are screened under the sieving action of the vibrating bodies 9-11, the materials meeting the particle size requirement pass through the sieve meshes 9-8 to flow into the material guide cylinder 10, then flow into the discharging cylinder 11, and the materials not meeting the particle size requirement are left in the sieve meshes 9-8.
After the materials are ground, stopping the motor 1 and the vibrating motor 9-16, taking out the materials in the blanking barrel 11, installing a waste collecting barrel into the blanking barrel 11, starting the screen overturning motor 9-1, driving the screen 9-8 and the screen fixing sleeve 9-9 to overturn for 180 degrees by the screen overturning motor 9-1, and automatically enabling the materials accumulated in the screen 9-8 to flow downwards into the waste collecting barrel in the blanking barrel 11 for recycling.
When the screen cloth 9-8 with different grain diameters needs to be replaced, the handle of the screen cloth drawer is used for drawing the screen cloth drawer 9-10 under the state that the whole equipment is stopped, the screen cloth fixing sleeve 9-9 on the screen cloth drawer 9-10 and the screen cloth 9-8 are drawn out together, the screen cloth 9-8 is dismounted and replaced by a new one, and then the screen cloth drawer 9-10, the screen cloth fixing sleeve 9-9 and the screen cloth 9-8 are pushed back to the original position, so that the whole screen cloth is replaced quickly.
The present invention is not limited to the above-described embodiments, and any obvious improvements, substitutions or modifications can be made by those skilled in the art without departing from the spirit of the present invention.
