A circulation channel 133 communicating with the receiving cavity 132 is provided in the side wall of the square rod 10. A circulation cavity 134 communicating with the circulation channel 133 is provided in the driving seat 7. Uniformly arranged on the side wall of the circulation cavity 134 are one-way air outlet pipes 135 extending to the outside of the driving seat 7. The outlet end of the one-way air outlet pipe 135 is located below the crushing seat 5. A rotating shaft 136 connected to the motor II 137 at the inner bottom of the barrel 1 is further provided in the receiving cavity 132. A fan blade I 138 is provided on the rotating shaft 136 in the receiving cavity 132.

[0024] The circulation mechanism II 14 includes an annular groove 141 sleeved around the sieve frame II 122. A slag discharge pipe 142 extending directly above the opening of the annular groove 141 is provided at the bottom of the side wall of the sieve frame I 121. In this embodiment, the side walls of the sieve frame I 121 and the sieve frame II 122 are solid structures. An electromagnetic valve is provided on the slag discharge pipe 142. A conveying auger 143 passing through the bottom wall of the annular groove 141 is provided on one side inside the barrel 1. When the motor II 137 works to drive the rotating shaft 136 to rotate, it can drive the conveying auger 143 to work through a transmission belt 144. A feed inlet 145 communicating with the conveying auger 143 is provided on the side wall of the annular groove 141. The top end of the conveying auger 143 is inclined downward and provided with a discharge channel 146 communicating with the crushing cavity 8.

[0025] The outer arc walls of the crushing seat 5 and the grinding seat 6 are both fixedly connected to the inner wall of the barrel 1. A guide slope 15 is provided around the edge of the top corner inside the opening of the crushing seat 5. The feed pipe 3 is located directly above the guide slope 15. The driving seat 7 is composed of two sets of conical metal seats, with the lower metal seat inverted. A crushing end face corresponding to the top end face of the upper metal seat is provided around the bottom of the crushing seat 5. A crushing cavity 8 is formed between the crushing end face and the top end face of the upper metal seat. Semi-circular crushing protrusions 16 are uniformly provided on the upper and lower end faces of the crushing cavity 8. A grinding end face corresponding to the bottom end face of the lower metal seat is provided around the top of the grinding seat 6. A grinding cavity 9 is formed between the grinding end face and the bottom end face of the lower metal seat.

[0026] The outer arc wall of the annular groove 141 is fixedly connected to the inner wall of the barrel body 1. The inner bottom wall of the opening of the annular groove 141 is inclined. The conveying auger 143 includes a cylinder body 1431 disposed at the lowest end of the inner bottom wall of the annular groove 141. Both the upper and lower ends of the cylinder body 1431 are hermetically arranged. A driving shaft 1432 is further disposed inside the cylinder body 1431. Spiral blades 1433 are arranged on the driving shaft 1432. Belt pulleys for fixing the transmission belt 144 are arranged at the bottom end of the driving shaft 1432 and on the rotating shaft 136. When the slag discharge pipe 142 is opened, the large-volume materials obtained by screening in the screen frame I 121 can flow into the annular groove 141 through the slag discharge pipe 142. The materials flow along the inclined surface of the inner bottom wall of the annular groove 141 to its lowest end, and then enter the cylinder body 1431 through the feed port 145. At this time, the motor II 137 drives the rotating shaft 136 to rotate, so that the rotating shaft 136 drives the driving shaft 1432 to rotate together through the belt pulley and the transmission belt 144. The driving shaft 1432 drives the spiral blades 1433 to rotate, thereby conveying the materials flowing into the cylinder body 1431 upward and sliding down through the discharge channel 146 into the crushing cavity 8 for re-crushing work.

[0027] As Figure 2 shown, a spring 21 is sleeved on the square rod 10 between the screen frame I 121 and the convex seat 131. A square tube 22 sleeved on the square rod 10 is arranged on the inner bottom wall of the screen frame I 121. A fan blade II 23 is arranged on the square rod 10 above the square tube 22. A fan blade III 24 located inside the screen frame II 122 is radially arranged on the outer wall of the convex seat 131.

[0028] A cylinder 17 sleeved on the top end of the screen frame I 121 is arranged at the bottom of the grinding seat 6. A round tube 18 is arranged at the top of the side wall of the cylinder 17. A dust removal cloth bag 19 is fixed on the round tube 18 by a clamp. A manhole 20 corresponding to the dust removal cloth bag 19 is further arranged on the side wall of the barrel body 1. As Figure 2 shown, the cylinder 17 prevents the materials falling after grinding from scattering outside the screen frame I 121, so that the materials are guided by it and fall into the screen frame I 121 for screening work. At the same time, when the airflow generated by the rotating fan blade II 23 and the airflow flowing downward in the grinding cavity 9 drive the materials to flow downward, the diffused dust and airflow can be discharged through the round tube 18. At this time, the dust removal cloth bag 19 can filter the dust in the airflow to prevent it from being discharged together with the airflow and affecting the working environment. And subsequently, the dust removal cloth bag 19 can be replaced and other work can be carried out by opening the manhole 20 and entering the barrel body 1.

[0029] Usage method of the present invention: The raw materials are introduced into the barrel body 1 through the feed pipe 3. Among them, the raw materials are guided by the diversion inclined surface 15 to flow into the crushing cavity 8. At this time, the motor I 11 drives the driving seat 7 to rotate through the square rod 10. The rotating driving seat 7 drives the crushing protrusions 16 to rotate in the crushing cavity 8, thereby performing the crushing work on the raw materials in the crushing cavity 8. The crushed materials will fall on the grinding end surface and flow downward along the top inclined surface thereof, and finally flow into the grinding cavity 9. At this time, the rotating driving seat 7 and the grinding end surface will perform the grinding work on the raw materials in the grinding cavity 9. Among them, the ground raw materials fall into the sieve frame I 121 through the opening in the middle of the grinding seat 9 for screening;

[0030] Such as Figure 2As shown, the raw materials falling into the sieve frame I121 are screened by the aperture of its bottom wall. Among them, the raw materials with large volume accumulate inside, while the raw materials with small volume are screened into the sieve frame II122. At this time, the aperture of the bottom wall of the sieve frame II122 can perform secondary screening on the raw materials inside, so as to realize multi-stage screening of the raw materials. When the sieve frame I121 and the sieve frame II122 in the screening mechanism 12 screen the raw materials, during this process, the motor I11 drives the square rod 10 to drive the driving seat 7 to process the raw materials in the crushing cavity 8 and the grinding cavity 9. At this time, the square rod 10 will also drive the square tube 22 and the screening mechanism 12 to rotate together by pressing against the square tube 22 with its side wall. Furthermore, by rotating the sieve frame I121 and the sieve frame II122 in the screening mechanism 12, the screening efficiency and effect of the raw materials inside are accelerated. When the square rod 10 drives the screening mechanism 12 to rotate through the square tube 22, a centrifugal force will be generated, which will cause the screening mechanism 12 to drive the square tube 22 to move downward on the square rod 10 and compress the spring 21 to make it contract. Or when there are raw materials accumulated in the screening mechanism 12, under the extrusion of the gravity of the raw materials, the screening mechanism 12 drives the square tube 22 to move downward on the square rod 10 and compress the spring 21 to make it contract. During the above process, when the screening mechanism 12 moves up and down, it will drive the sieve frame I121 to move up and down in the same direction on the cylinder 17, and drive the sieve frame II122 to move up and down in the same direction in the annular groove 141. It should be noted that when the screening mechanism 12 moves downward, it will not drive the slag discharge pipe 142 to contact the top of the annular groove 141 to prevent violent collision between the two. At the same time, when the screening mechanism 12 moves upward, it will not drive the square tube 22 to contact the fan blade II23 to prevent violent collision between the two. During the above process, when the square rod 10 rotates, it will drive the fan blade II23 to rotate to generate a downward suction force, which will accelerate the downward discharge of the raw materials in the grinding cavity 9, and can also play a role in dispersing the falling raw materials to prevent them from agglomerating and affecting subsequent screening. At the same time, the square rod 10 will also drive the fan blade III24 to rotate through the convex seat 131 to blow the raw materials in the sieve frame II122 and accelerate the screening efficiency of the raw materials inside. When the extrusion force on the spring 21 by the screening mechanism decreases, the contracted spring 21 will stretch and push the screening mechanism 12 to move upward, thus realizing a certain range of up and down jittering of the screening mechanism 12 to accelerate the screening efficiency and effect of the raw materials inside;

[0031] When it is necessary to recycle and reprocess the raw materials with different volumes obtained by screening in the screen frame I 121 and the screen frame II 122 after the processing of the raw materials is completed, the solenoid valve on the slag discharge pipe 142 is opened. At this time, the rotating screening mechanism 12 can drive the large-volume raw materials in the screen frame I 121 to be introduced into the opening of the annular groove 141 through the slag discharge pipe 142, and then flow along the inclined plane of the inner bottom wall of the opening of the annular groove 141 to its bottommost end, and finally flow into the conveying auger 143 through the feed port 145. At the same time, the motor II 137 drives the fan blade I 138 to rotate through the rotating shaft 136. At this time, the rotating shaft 136 drives the drive shaft 1432 and the spiral blade 1433 to rotate through the pulley and the transmission belt 144, so as to convey the large-volume raw materials flowing into the cylinder 1431 to the discharge channel 146 and introduce them into the crushing cavity 8 for crushing, and then grind and screen them. When the rotating shaft 136 drives the fan blade I 138 to rotate in the accommodation cavity 132, a suction force will be generated, which will generate an upward suction force on the small-volume raw materials in the screen frame II 122. At this time, the rotating fan blade III 24 can blow the raw materials at the bottom of the screen frame II 122 to facilitate their lifting below the convex seat 131, and the lifted raw materials are convenient to be extracted into the accommodation cavity 132, enter the circulation cavity 134 through the circulation channel 133, and are discharged to the lower part of the crushing seat 5 through a number of one-way air outlet pipes 135. Then, under the influence of the suction force generated by the rotation of the rotating fan blade II 23, the air flow mixed with the raw materials can conveniently enter the grinding cavity 9 for grinding, and at the same time, this part of the air flow can also accelerate the flow of the raw materials in the grinding cavity 9. In the above process, in order to facilitate the suction force generated by the operation of the fan blade I 138 in the accommodation cavity 132 to only act on the raw materials at the bottom of the screen frame II 122 to extract them, preventing the diffusion of the suction force from affecting the extraction of the raw materials at the bottom of the screen frame II 122, a sealing plate for the rotating shaft 136 to pass through can be provided below the screen frame II 122, and the sealing plate is driven by an electric push rod. Then, when extracting the raw materials at the bottom of the screen frame II 122 by the suction force generated by the rotating fan blade I 138 in the accommodation cavity 132, the electric push rod drives the sealing plate to move upward to seal the aperture of the bottom wall of the screen frame II 122, and the sealing plate returns to its original position after the work is completed; when the raw materials after cyclic crushing and grinding enter the screening mechanism 12 again, continue to screen them. At this time, if there are still unqualified raw materials, they can continue to be subjected to corresponding crushing and grinding processing in the above manner until the processing effect of the raw materials meets the standard.

[0032] The present invention drives the driving seat 7 to rotate in the crushing chamber 8 and the grinding chamber 9 through the motor I11 and the square rod 10 to perform the crushing and grinding work on the raw materials. At the same time, the rotating square rod 10 drives the screening mechanism 12 to classify and screen the unqualified raw materials after crushing and grinding. At this time, the motor II137 in the circulation mechanism I13 drives the fan blade I135 to work through the rotating shaft 136 to generate suction, and then the small-volume raw materials in the sieve frame II122 are introduced into the grinding chamber 9 through the accommodation chamber 132, the circulation channel 133, the circulation chamber 134 and the one-way air outlet pipe 135 for re-grinding work. The rotating rotating shaft 136 drives the conveying auger 143 in the circulation mechanism II14 to rotate through the transmission belt 144. At this time, the large-volume raw materials in the sieve frame I121 enter the conveying auger 143 through the slag discharge pipe 142, the annular groove 141 and the feed port 145, and are introduced into the crushing chamber 8 through the conveying auger 143 and the discharge channel 146 for re-crushing. Then, after being ground by the grinding chamber 9, it is finally screened by the screening mechanism 12. In this way, the raw materials are classified and screened through the above method, and the raw materials of different sizes and volumes are introduced into the corresponding crushing chamber 8 or grinding chamber 9 for processing, preventing the raw materials of different sizes obtained by screening from being only introduced into the grinding chamber 9, which affects the grinding effect of the raw materials.

[0033] The above has described the present invention in detail, but the above content is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
