[0037] Working principle: when using the device, after putting the material into the feeding port at the top of the processing tank 2, the motor 3 is started to change the position of the material while drying it, and the rotation of the motor 3 drives the rotation of the rotating rod 4, and the rotation of the rotating rod 4 drives the rotation of the connecting plate 5, and the rotation of the connecting plate 5 drives the rotation of the connecting block 6, and the rotation of the connecting block 6 drives the rotation of the limiting tube 7, and the rotation of the limiting tube 7 drives the rotation of the sliding rod 10, and the rotation of the sliding rod 10 drives the scraper 11 to flip the material, and the elasticity of the spring 9 at the top of the sliding rod 10 makes the scraper 11 fit the surface of the processing disk 12 more closely, and the unloading trough of the processing disk 12 at the top is opened on the outside, and the unloading trough of the processing disk 12 at the bottom is opened in the middle, The position and direction of the scraper 11 are different, so that the drying of the material is more comprehensive. The material is scraped to the outside of the limit block 13 and then rolled onto the surface of the auger frame 18. The rotation of the rotating rod 4 drives the rotation of the bevel gear 14, and the rotation of the bevel gear 14 drives the rotation of the bevel gear 2 17. The rotation of the bevel gear 2 17 drives the rotation of the support rod 16, and the rotation of the support rod 16 drives the rotation of the auger frame 18. The material is discharged by the rotation of the auger frame 18. When the equipment is running, the two clamping blocks 24 connected to the outside absorb the vibration and transmit it to the surface of the spring 2 23 and the telescopic column 22. The elasticity of the spring 23 absorbs the vibration and drives the clamping block 24 to reset, thereby reducing the noise of the equipment during operation.
