The top of the stirring frame is rotatably connected to the device body, and the bottom of the stirring frame extends into the device body. The reduction motor is used to drive the stirring frame to rotate. When the granular raw material to be mixed is passed into the device body from the feed pipe, the reduction motor is driven, so that the reduction motor drives the stirring frame to rotate, thereby dispersing and mixing the raw materials.

[0039] Reference Figure 2 and Figure 3 Each pulley 513 is fixedly mounted on the corresponding dispersion roller 52, and each belt 514 is mounted on the corresponding pulley 513 and the driving wheel 512, so that the driving wheel 512 drives the pulley 513 to rotate. The connecting line between the driving wheel 512 and the corresponding pulley 513 is parallel to the length direction of the corresponding connecting frame 613, and the distance between the connecting lines is equal to the distance between the rotation points of the corresponding connecting frame 613.

[0040] Reference Figure 1 and Figure 2 A plurality of guide plates 41 are also provided at the bottom of the dispersion box 4. In the embodiment of the present application, the number of the guide plates 41 is set to two, and the two guide plates 41 are respectively located at the two ends of the dispersion box 4 along its own length direction. The top end of each guide plate 41 is fixedly connected to the bottom end of the dispersion box 4 by welding, and the other end is tilted downward so that the bottom ends of the two guide plates 41 are offset to a position close to each other, so as to guide the raw materials passing out from the bottom of the dispersion box 4.

[0041] Reference Figure 1 , Figure 2 and Figure 3 A screening mechanism 7 is also provided below the guide plate 41, and the screening mechanism 7 includes a screening net 71 and a screening assembly 72. The screening net 71 is provided directly below the two guide plates 41, so that the raw materials passing through the guide plates 41 can be screened by the mesh in the middle of the screening net 71. The screening net 71 is slidably connected to the device body 1 through a slide rail, and the sliding direction is the length direction of the device body 1, so as to fully screen the raw materials passing through the guide plates 41.

[0042] Reference Figure 1 and Figure 3 The screening assembly 72 includes a driving member 721, a crank frame 722 and a transmission frame 723. A rotating portion 7221 extends from the bottom of the crank frame 722. The rotating portion 7221 is inserted into the device body 1 and is rotatably connected to the device body 1 through a bearing. The other end of the crank frame 722 is rotatably connected to one end of the transmission frame 723 through a pin shaft, and the other end of the transmission frame 723 is slidably connected to the screening net 71 through a pin shaft.

[0043] Reference Figure 3 The length of the transmission frame 723 is greater than that of the crank frame 722, so that the crank frame 722 can make a circular motion, and the transmission frame 723 can swing back and forth under the drive of the crank frame 722, so that a crank slider mechanism is formed between the crank frame 722, the transmission frame 723 and the screening net 71, thereby realizing the driving of the screening net 71 to slide back and forth.

[0044] Reference Figure 3 The driving member 721 includes a bevel gear 7211 and a linkage frame 7212, and the number of the bevel gears 7211 is set to two. The linkage frame 7212 is vertically arranged, and the top of the linkage frame 7212 extends upward to the sliding frame 612, and is rotatably connected to the sliding frame 612 through a bearing. One bevel gear 7211 is fixedly sleeved on the output shaft of the rotating motor 5111, and the other bevel gear 7211 is fixedly sleeved on the top of the linkage frame 7212, so that the rotating motor 5111 can drive the linkage frame 7212 to rotate through the two bevel gears 7211, thereby driving the linkage frame 7212.

[0045] Reference Figure 3 A plurality of protrusions 9 are set on the bottom end of the linkage frame 7212, and the plurality of protrusions 9 are evenly distributed at equal angles along the axis direction of the linkage frame 7212, and are integrally formed with the linkage frame 7212. A linkage groove 8 is also formed through the rotating portion 7221 of the crank frame 722, and the linkage groove 8 is adapted to the bottom shape of the linkage frame 7212.

[0046] Reference Figure 3 The bottom of the linkage frame 7212 extends downward and passes through the linkage slot 8, and abuts against the inner wall of the linkage slot 8. The rotation axis of the linkage frame 7212 is the same as the rotation axis of the crank frame 722, so that the linkage frame 7212 can slide relative to the crank frame 722 in the vertical direction, thereby adapting to the sliding of the sliding frame 612, and allowing the rotating motor 5111 to drive the crank frame 722 to rotate through the linkage frame 7212.

[0047] Reference Figure 3 When the adjusting member 611 drives the sliding frame 612 to slide in the vertical direction, the sliding frame 612 drives the two adjusting frames 62 to slide through the linkage frame 7212, thereby changing the spacing between the dispersion rollers 52. In this process, the sliding frame 612 drives the linkage frame 7212 to slide in the vertical direction, so that the bottom of the linkage frame 7212 slides relative to the crank frame 722, and the protrusion 9 on the linkage frame 7212 still abuts against the inner wall of the linkage groove 8 on the crank frame 722, so that the linkage frame 7212 can still drive the crank frame 722 to rotate.

[0048] Reference Figure 2 A hopper 10 is also provided directly below the screening net 71. The hopper 10 is fixedly mounted on the device body 1, and the top opening of the hopper 10 is larger than the bottom opening. The mixing box 3 is fixedly mounted on the device body 1 and is located directly below the hopper 10. The bottom end of the hopper 10 is fixedly connected to the top end of the mixing box 3, and the two are interconnected, so that the raw materials passed out of the hopper 10 can enter the mixing box 3.

[0049] Reference Figure 1 and Figure 2 In the embodiment of the present application, the mixing box 3 is set to be cylindrical, and the axial direction of the mixing box 3 is the same as the length direction of the device body 1. A discharge pipe 31 is also provided at the bottom end of the mixing box 3, and the top end of the discharge pipe 31 is fixedly connected to the mixing box 3 and communicated. In the embodiment of the present application, a valve for controlling the opening and closing of the discharge pipe 31 is also provided on the discharge pipe 31.

[0050] Reference Figure 2In the embodiment of the present application, the stirring mechanism 2 is configured as a combination structure of a reduction motor and a stirring frame. The reduction motor is fixedly installed at one end of the mixing box 3 along its own length direction, and the output shaft is fixedly connected to one end of the stirring frame. The axial direction of the stirring frame is the length direction of the mixing box 3. The main part of the stirring frame is located in the mixing box 3 and is used to stir the raw materials in the mixing box 3. The stirring mechanism 2 is a prior art and will not be described in detail.

[0051] The implementation principle of a raw material dispersing and mixing device in the embodiment of the present application is as follows: when in use, the raw material is introduced from the top of the dispersing box 4, and after being dispersed by the dispersing sheets 53 on the dispersing rollers 52, the raw material falls downward out of the dispersing box 4 through the gap between the dispersing rollers 52, and falls onto the screening net 71 under the guidance of the guide frame. The screening net 71 slides back and forth under the drive of the screening assembly 72, thereby screening the dispersed raw material. The screened raw material enters the mixing box 3 through the hopper 10, is fully mixed after being stirred by the stirring mechanism 2 in the mixing box 3, and is discharged through the discharge pipe 31 after being fully mixed.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
