[0033] Specifically, when the raw materials need to be fully mixed, the motor 4 is started to drive the rotating rod 5 to rotate. A plurality of stirring blades 6 and a connecting rod 11 are installed on the rotating rod 5. The rotation of these components can effectively stir the raw materials and make them mixed evenly. At the same time, the rotation of the rotating rod 5 also drives the gear 7 to rotate. Through the transmission of the gear 7 and the gear 2 8, the gear 2 8 further drives the rotating rod 2 9 to rotate. The auger blade 10 on the rotating rod 2 9 transfers the raw materials on the top of the reactor 1 to the top of the reactor 1, and then fully stirs them through the stirring blades 6, so as to prevent the raw materials from being stratified and affecting the granulation effect.

[0034] Reference Figure 4-Figure 6 The cleaning assembly includes a connecting rod 11, the outer wall of the connecting rod 11 is fixedly connected to the outer wall of the rotating rod 5, the interior of the connecting rod 11 is slidably connected to a moving rod 12, one end of the moving rod 12 is fixedly connected to a scraper 13, the outer wall of the scraper 13 fits the inner wall of the reactor 1, the other end of the moving rod 12 is fixedly connected to the other end of a spring 14, the other end of the spring 14 is fixedly connected to the interior of the connecting rod 11, the inner wall of the top plate 2 is fixedly connected to a hopper 15, the interior of the hopper 15 is fixedly connected to a plurality of long rods 22, the outer wall of the long rods 22 is fixedly connected to the inner wall of the reactor 1 A plurality of symmetrical partition blocks 23 are fixedly connected thereto, slots are formed inside the partition blocks 23, a motor 2 16 is fixedly connected to the outer wall of the hopper 15, a rotating rod 17 is fixedly connected to the output end of the motor 2 16, a driving gear 18 is fixedly connected to the outer wall of the rotating rod 17, a rotating rod 2 19 is rotatably connected to the inside of the hopper 15, a driven gear 20 is fixedly connected to the outer wall of the rotating rod 2 19, the driven gear 20 is meshed with the driving gear 18, and a cutting knife 21 is fixedly connected to the outer walls of the rotating rod 17 and the rotating rod 2 19.

[0035] Specifically, when the device is needed, the raw materials are put into the hopper 15. The raw materials first come into contact with a plurality of partition blocks 23 connected to the long rods 22. The design of these partition blocks 23 cleverly breaks up the raw materials and prepares them for subsequent processing. Next, the motor 2 16 is started, driving the rotating rod 17 to start rotating. The rotation of the rotating rod 17 further drives the driving gear 18 to rotate. Through the engagement of the driving gear 18 with the driven gear 20, the driven gear 20 also starts to rotate with the rotating rod 2 19 inside the hopper 15. During this process, the rotating rod 17 and the rotating rod 2 19 simultaneously drive the two sets of cutting knives 21 to rotate in the direction, so as to fully cut the raw materials and provide a good foundation for the subsequent mixing of the raw materials.

[0036] Reference Figure 6 The top of the reactor 1 is fixedly connected with a discharge pipe 24, the inside of which is rotatably connected with a valve 25, the top of the reactor 1 is fixedly connected with a connection block 26, the inside of which is fixedly connected with the output end of a vibration motor 27.

[0037] Specifically, after the raw materials are processed, the valve 25 is opened and the raw materials are discharged through the discharge pipe 24. In order to ensure smooth discharge of the raw materials and prevent blockage of the discharge pipe 24, the vibration motor 27 connected to the connecting block 26 will be started to drive the bottom of the reactor 1 to vibrate. This vibration design helps to eliminate the blockage of the raw materials during the discharge process and ensure the continuity and stability of the production process.

[0038] Working principle: When the device needs to be used, first put the raw materials into the hopper 15. First, the raw materials contact the multiple partition blocks 23 connected by the long rod 22 to break up the raw materials. At the same time, start the motor 2 16 to drive the rotating rod 1 17 to rotate. The rotation of the rotating rod 17 drives the driving gear 18 to rotate. The rotation of the driving gear 18 drives the driven gear 20 to rotate. The driven gear 20 drives the rotating rod 2 19 to rotate inside the hopper 15. The rotating rod 1 17 and the rotating rod 2 19 drive the two sets of cutting knives 21 to rotate in the direction to fully cut the raw materials in preparation for the subsequent full mixing of the raw materials. When the raw materials need to be fully mixed, start the motor 14 The rotating rod 15 rotates, and the rotating rod 15 rotates with multiple stirring blades 6 and the connecting rod 11. When the rotating rod 15 rotates, it rotates with the gear 17, and the gear 28 is rotated by the gear 17. The rotation of the gear 28 rotates the rotating rod 29, and the rotating rod 29 rotates with the auger blade 10.
