[0041] like Figure 7-Figure 8 As shown, the reverse driving member includes a first friction wheel 400 arranged at the lower end of the stirring outer shaft 411 and a second friction wheel 401 arranged at the lower end of the stirring outer shaft 411, a second rotating ring 404 is rotatably arranged at the top of the base 103 above the first friction wheel 400, and the second rotating ring 404 is connected to the first friction wheel 400 through a first extrusion spring 405, an auxiliary rotating shaft 402 is slidably arranged at the middle position of the lower end of the second friction wheel 401, and the lower end of the auxiliary rotating shaft 402 is rotatably connected to the base 103, a supporting outer disk 407 is arranged on the outer side of the auxiliary rotating shaft 402, and the supporting outer disk 407 is connected to the second friction wheel 401 through a second extrusion spring 406, and a friction driving unit for driving the first friction wheel 400 and the second friction wheel 401 to rotate in the opposite direction is also arranged inside the base 103, and under the push of the first extrusion spring 405 and the second extrusion spring 406, the first friction wheel 400 and the second friction wheel 401 are relatively squeezed, so as to be in close contact with the friction driving unit;

[0042] like Figure 8As shown, the friction drive unit includes an elliptical drive disk 412, which is arranged between the first friction wheel 400 and the second friction wheel 401. The outer side of the elliptical drive disk 412 is in friction contact with the first friction wheel 400 and the second friction wheel 401. The elliptical drive disk 412 is an elliptical structure, and the first friction wheel 400 and the second friction wheel 401 are conical structures. The elliptical drive disk 412 is fixedly arranged at the end of a transmission shaft 416, and the transmission shaft 416 is connected to a lateral pushing mechanism for driving its lateral movement. The transmission shaft 416 A plurality of rotation limiting protrusions 415 are distributed in the outer array, a second bevel gear 424 is provided with a sliding sleeve on the transmission shaft 416, a limiting groove matching the rotation limiting protrusion 415 is provided on the inner wall of the second bevel gear 424, a transmission shaft sleeve 414 is rotatably provided at the end of the second bevel gear 424, and there is a clearance fit between the transmission shaft sleeve 414 and the transmission shaft 416, the outer side of the transmission shaft sleeve 414 is fixedly connected to the top of the base 103 through a suspension rod frame 417, and a driving motor 403 is installed inside the base 103 where the second bevel gear 424 is located. A driving shaft 413 is provided at the output end of the driving motor 403, and a first bevel gear 423 meshing with the second bevel gear 424 is provided at the upper end of the driving shaft 413, so that the driving shaft 413 and the first bevel gear 423 can be driven to rotate by the driving motor 403, and the first bevel gear 423 matches with the second bevel gear 424 to drive the transmission shaft 416 to rotate, and the transmission shaft 416 drives the elliptical driving disk 412 to rotate, thereby obtaining stirring power, and the elliptical driving disk 412 can be driven to move toward the first friction wheel 400 and the second friction wheel 401 through the lateral pushing mechanism. The first friction wheel 400 and the second friction wheel 401 are of a conical structure, so under the extrusion of the elliptical drive disk 412, the first friction wheel 400 and the second friction wheel 401 will stagger and slide, so that the initial staggered amplitude of the first knife seat 301 and the second knife seat 305 can be adjusted, so as to fine-tune the stirring effect. Since the elliptical drive disk 412 here is an elliptical structure, when the elliptical drive disk 412 is driven, the first friction wheel 400 and the second friction wheel 401 will float up and down intermittently, so that the stirring area can be driven to float up and down, and finally the stirring effect is improved;

[0043] like Figure 8As shown, the lateral pushing mechanism includes a suspension rod frame 417 rotatably connected to the transmission shaft 416, a fine-tuning sleeve 420 is provided on the base 103 where the suspension rod frame 417 is located, and the suspension rod frame 417 is slidably arranged in the fine-tuning sleeve 420, and a fine-tuning screw hole 419 is provided at the end of the suspension rod frame 417, and a fine-tuning screw rod 422 is matched in the fine-tuning screw hole 419, and the fine-tuning screw rod 422 is rotatably connected to the end of the fine-tuning sleeve 420, and the outer end of the fine-tuning screw rod 422 is connected to the fine-tuning sleeve 420. The handle 421 is connected and fixed, and the fine-tuning screw 422 is driven to rotate by the fine-tuning handle 421. The fine-tuning screw 422 matches the fine-tuning screw hole 419, thereby pushing the fine-tuning slide 418 to slide along the fine-tuning sleeve 420, so that the transmission shaft 416 can be driven to move horizontally, providing thrust for the horizontal displacement of the elliptical driving disk 412. The fine-tuning handle 421 is provided with an indicator arrow, and the outer side of the base 103 is provided with a scale ring matching the indicator arrow, so as to provide a reference for rotating the fine-tuning handle 421;

[0044] like Figure 10-11 As shown, the crushing component 200 includes a crushing frame 207, and the crushing frame 207 matches the inner wall of the mixing drum 100. The inner wall of the mixing drum 100 is provided with a supporting ring 106 for holding the bottom of the crushing frame 207. The inner side of the cover 101 is provided with a downward pressing positioning ring 105 for pressing the upper end of the crushing frame 207 to achieve positioning. The upper end of the crushing frame 207 is also provided with a buffering washer 104 matching the downward pressing positioning ring 105. The buffering of the buffering washer 104 is used to improve the positioning effect. The bottom of the crushing frame 207 is provided with a filter disc 201, and a plurality of filter holes are distributed on the filter disc 201. A crushing shaft 202 is rotatably provided in the middle position of the filter disc 201. A plurality of cleaning brushes 206 are distributed in an array outside the crushing shaft 202. The lower end of the crushing shaft 202 is provided with a transmission member matching the stirring component, and the crushing shaft 202 is driven by the transmission member to rotate rapidly, so that the cleaning brush 206 crushes the material in the crushing frame 207 to crush the material.

[0045] The crushing frame 207 is detachably connected. If crushing is not required during actual processing, the crushing frame 207 can be removed from the mixing drum 100, thereby improving the flexibility of the equipment.

[0046] The transmission member includes an elastic sleeve 203 fixedly arranged at the lower end of the crushing shaft 202, an elastic slide rod 205 with a rectangular cross section is slidably arranged in the lower end hole of the elastic sleeve 203, the upper end of the elastic slide rod 205 is connected to the elastic sleeve 203 by an expansion spring, and a movable friction disk 204 is arranged at the lower end of the elastic slide rod 205. A cleaning brush 206 for cleaning the screening position of the filter disc 201 is fixedly arranged on the outer side of the elastic sleeve 203, so that when the elastic sleeve 203 rotates, the cleaning brush 206 can clean the blocked materials on the filter disc 201. Thereby ensuring smooth filtration, the movable friction disk 204 is in frictional contact with the stirring component, so that the friction force is used to drive the movable friction disk 204 to rotate, and the movable friction disk 204 drives the elastic sleeve 203 to rotate, and the elastic sleeve 203 drives the crushing shaft 202 to rotate, so as to obtain cutting power. Even when the limit shaft 409 floats up and down, the movable friction disk 204 will also float up and down at the lower end of the elastic sleeve 203 with the elastic slide bar 205. Under the action of the expansion spring, the movable friction disk 204 will always be in contact with the friction transmission surface 408 to maintain tight pressure, thereby obtaining rotational power for the transmission part.

[0047] Working principle: When in use, if the material needs to be pre-crushed, the crushing component 200 needs to be installed on the mixing drum 100 first. At this time, the lower end of the crushing frame 207 is pressed against the supporting ring 106, and the downward positioning ring 105 on the inner side of the cover 101 presses down the upper end of the crushing frame 207, thereby completing the locking of the position of the crushing frame 207;

[0048] Then, the material is put into the hopper 102. Under the transmission of the transmission member, the crushing shaft 202 will rotate rapidly, and the cleaning brush 206 on the outer side of the crushing shaft 202 will crush the material on the crushing frame 207. The qualified material will pass through the filter disc 201 and enter the mixing drum 100. In this way, when the elastic sliding sleeve 203 rotates, the cleaning brush 206 can clean the blocked material on the filter disc 201, thereby ensuring smooth filtration.

[0049] After the processed material enters the mixing drum 100, the driving motor 403 drives the driving shaft 413 and the first bevel gear 423 to rotate, and the first bevel gear 423 matches with the second bevel gear 424 to drive the transmission shaft 416 to rotate, and the transmission shaft 416 drives the elliptical driving disk 412 to rotate, and the friction between the elliptical driving disk 412 and the first friction wheel 400 and the second friction wheel 401 will drive the limiting shaft 409 and the stirring outer shaft 411 to rotate in the opposite direction at high speed, and the stirring outer shaft 411 will drive the first knife seat 301 to rotate, and the limiting shaft 409 will drive the second knife seat 305 to rotate, and the second stirring plate 306 outside the second knife seat 305 and the first stirring plate 307 outside the first knife seat 301 will rotate in the opposite direction, so as to quickly mix the materials inside the mixing drum 100;

[0050] Since the elliptical driving disk 412 is an elliptical structure, when the elliptical driving disk 412 is driven, the first friction wheel 400 and the second friction wheel 401 will float up and down intermittently, so that the stirring area can be driven to float up and down, and finally the stirring effect is improved;

[0051] The fine-tuning screw 422 is driven to rotate by the fine-tuning handle 421, and the fine-tuning screw 422 matches the fine-tuning screw hole 419, so as to push the fine-tuning slide 418 to slide along the fine-tuning sleeve 420, so as to drive the transmission shaft 416 to move horizontally, and provide thrust for the horizontal displacement of the elliptical driving disk 412. In this way, under the extrusion of the elliptical driving disk 412, the first friction wheel 400 and the second friction wheel 401 will stagger and slide, so that the initial staggering range of the first knife seat 301 and the second knife seat 305 can be adjusted, so as to fine-tune the stirring effect;

[0052] When the first knife seat 301 and the second knife seat 305 need to be disassembled later, it is only necessary to loosen the locking nut 107 and disassemble them. At this time, the second knife seat 305 and the first knife seat 301 can be taken away. The disassembly is simple and convenient. It should be noted that the second knife seat 305 and the first knife seat 301 can rotate along with the limiting shaft 409 and the stirring outer shaft 411 based on the friction between the two. The upper end surface of the stirring inner shaft 410 and the upper end surface of the knife seat support ring 425 are provided with an anti-slip layer.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
