The first power assembly 12 is connected to the stirring assembly 13 by transmission, and the first power assembly 12 can drive the stirring assembly 13 to move along a larger circle in the box 11, so that the stirring assembly 13 can stir the raw materials in the box 11 in a large range. In actual use, a mounting frame (not shown in the figure) can be used to fix the mixing structure 1 to prevent the mixing structure 1 from tilting or shaking. The support frame is a relatively conventional technology and will not be described in detail.

In this process, other parts do not affect the free rotation of the output shaft of the second motor 131.

[0025] The second motor 131 can also drive the stirring unit 137 to rotate along a smaller circle. Specifically, the tail of the output shaft of the second motor 131 is coaxially fixedly connected with the first pulley 135, and the first pulley 135 is connected to the stirring unit 137 through a belt 136. It can be understood that the first pulley 135 can be separated from the rotating disk 134, or can be connected to the rotating disk 134, as long as the rotating disk 134 does not affect the rotation of the first pulley 135.

[0026] Preferably, the number of the stirring units 137 is three, and the three stirring units 137 are evenly spaced along the outer circumference of the rotating disk 134. As an implementation of the stirring unit 137, please refer to Figure 4 and Figure 5The stirring unit 137 includes a second pulley 1371, a third gear 1372, a fourth gear 1373, a fifth gear 1374, a rotating wheel 1375, a connecting block 1376 and a stirring rod 1377, and the above pulleys and gears are all connected to the rotating disk 134 through the shaft.

When in use, the first pulley 135 drives the second pulley 1371 to rotate, the second pulley 1371 drives the third gear 1372 to rotate, the third gear 1372 drives the fourth gear 1373 to rotate, the fourth gear 1373 drives the two fifth gears 1374 to rotate, the fifth gear 1374 drives the rotating wheel 1375 to rotate, and the two rotating wheels 1375 drive the connecting block 1376 to rotate within a smaller circumference, so that the stirring rod 1377 stirs the raw materials within a smaller circumference.

[0027] Please refer to Figure 6 , a shielding structure 3 is arranged at the bottom of the discharge port 14, and the shielding structure 3 can control the switch of the discharge port 14. Specifically, the shielding structure 3 includes a baffle 31, a rotating arm 32, a slide rail 33, a slider 34 and an electric push rod 35. The baffle 31 is rotatably arranged at the bottom of the box body 11, and a discharge channel 311 is opened in the baffle 31. The shape of the discharge channel 311 is the same as that of the discharge port 14. The baffle 31 is rotatably connected to one end of the rotating arm 32, and the other end of the rotating arm 32 is rotatably connected to the slider 34. The slider 34 is slidably arranged in the slide rail 33, and the slide rail 33 is fixedly arranged at the bottom of the box body 11. One side of the slider 34 is fixedly connected to the movable end of the electric push rod 35, and the fixed end of the electric push rod 35 is fixedly connected to the bottom of the box body 11.

[0028] When in use, the electric push rod 35 telescopically moves, which can drive the slider 34 to move along the slide rail 33. The movement of the slider 34 can drive the rotating arm 32 to rotate, and the rotating arm 32 drives the baffle 31 to rotate. During the rotation of the baffle 31, the discharge channel 311 can be connected with the discharge port 14, and the raw materials in the box body 11 can leave the box body 11 through the discharge port 14 and the discharge channel 311. During the rotation of the baffle 31, the discharge channel 311 can also intersect with the discharge port 14. At this time, the discharge port 14 is blocked by the baffle 31, and the raw materials cannot leak out of the box body 11 from the discharge port 14.

[0029] The raw materials leaking out of the box 11 from the discharge port 14 enter the crushing structure 2 and are crushed in the crushing structure 2. Figure 1 The crushing structure 2 includes a feed hopper 21, an abrasive assembly 22 and a second power assembly 23. The top of the feed hopper 21 is fixedly connected to the bottom of the box 11, and the bottom of the feed hopper 21 is connected to the abrasive assembly 22. When in use, the raw material enters the abrasive assembly 22 from the box 11 through the hopper 21. The second power assembly 23 is connected to the abrasive assembly 22 in a transmission manner.

[0030] The abrasive assembly 22 includes an abrasive barrel 221, a cover 222, a stationary toothed disc 223, a moving cutter disc 224, a screen 225, a workbench 226 and a material guide channel 227. The abrasive barrel 221 is fixedly arranged on the top of the workbench 226, and the abrasive barrel 221 is arranged horizontally. The cover 222 is openably arranged at the barrel mouth of the abrasive barrel 221, the middle part of the cover 222 is connected to the bottom of the feed hopper 21, and the inner side of the cover 222 is fixedly connected to the stationary toothed disc 223. During the operation of the abrasive assembly 22, the cover 222 is fixedly arranged at the barrel mouth of the abrasive barrel 221. The moving cutter disc 224 is rotatably arranged inside the abrasive barrel 221, and the moving cutter disc 224 is transmission-connected to the second power assembly 23, and the second power assembly 23 provides the moving cutter disc 224 with the power for rotation, and the second power assembly 23 can also be fixedly arranged on the workbench 226. The screen 225 is fixedly arranged in the abrasive barrel 221, and the screen 225 is arranged outside the moving cutter disc 224, and a certain size of gap is left between the screen 225 and the abrasive barrel 221. The material guide channel 227 is fixedly arranged below the abrasive barrel 221, and the material guide channel 227 is connected to the abrasive barrel 221.

[0031] The method of using the abrasive assembly 22 is to first fix the cover 222 on the mouth of the abrasive barrel 221. At this time, the protrusions of the static tooth disc 223 and the crushing knives of the moving cutter disc 224 are arranged at intervals, and the feed raw materials are located inside the screen 225. The second power assembly 23 is started, and the second power assembly 23 drives the moving cutter disc 224 to rotate. Under the cooperation of the moving cutter disc 224 and the static tooth disc 223, the feed raw materials are crushed. When the particle size of the feed raw materials is smaller than the mesh of the screen 225, the feed raw materials leak out of the screen 225 and enter the material guide channel 227. At this time, it is only necessary to collect the crushed feed raw materials at the outlet of the material guide channel 227. Obviously, the particle size of the feed raw materials can be controlled by replacing the screen 225 with different mesh sizes.

[0032] The second power assembly 23 is a prior art, and only needs to provide power for the moving cutter disc 224. For example, the second power assembly 23 can be a third motor, the third motor is fixedly connected to the workbench 226, the output shaft of the third motor passes through the abrasive barrel 221 and is coaxially fixedly connected to the moving cutter disc 224, and the third motor drives the moving cutter disc 224 to rotate.
