By setting the scraper 15, the first motor 4 can drive the toothed plate cover 7 to rotate to drive the stirring rods 16 to carry out the stirring work. At the same time, the rotation of the toothed plate cover 7 drives the scraper 15 to rotate and scrape the inner wall of the mixing drum 2 for cleaning, preventing waste of raw materials. The number of scrapers 15 is multiple and is evenly distributed in a rectangular array on the outer surface of the toothed plate cover 7, so that the scraper 15 can better scrape and clean the inner wall of the mixing drum 2. The number of stirring rods 16 is multiple and is evenly distributed in a rectangular array on the outer surface of the fixing rod 17, so that the stirring rods 16 can better carry out the stirring work. An annular chute 19 is opened at the top end of the mixing drum 2, and a plurality of uniformly distributed sliders 18 are slidably connected inside the annular chute 19. The outer surface of the slider 18 is fixedly connected to the outer surface of the toothed plate cover 7, so that the toothed plate cover 7 can slide on the top end of the mixing drum 2. A feed inlet 9 is fixedly communicated with the top end of the storage tank 3, and a discharge outlet 11 is fixedly communicated with the bottom of the mixing drum 2, so that the staff can put the raw materials into the storage tank 3 through the feed inlet 9, and the stirred raw materials can be discharged through the discharge outlet 11. Support feet 10 are fixedly connected to the four corners of the bottom end of the installation base plate 1, so that the device can be stably placed on the ground.

[0019] A second motor 8 is fixedly connected to the outer surface of the storage tank 3. One end of the output shaft of the second motor 8 is fixedly connected to a feeding wheel 22. A baffle 23 is slidably connected inside the storage tank 3. A spring 24 is fixedly connected to the outer surface of the baffle 23. The end of the spring 24 away from the baffle 23 is fixedly connected to the inner side of the storage tank 3. A pulling rope 20 is fixedly connected to the middle of the baffle 23. The end of the pulling rope 20 away from the baffle 23 is fixedly connected to a fixed block 21. A scale groove plate 14 is fixedly connected to the outer surface of the storage tank 3. The inner part of the scale groove plate 14 is slidably connected to the outer surface of the fixed block 21. A first transmission wheel 12 is fixedly connected to the outer surface of the storage tank 3. A second transmission wheel 13 is fixedly connected to the outer surface of the storage tank 3. By setting the linkage of the spring 24, the pulling rope 20 and the scale groove plate 14, under the elastic force of the spring 24, as the raw material decreases, the pulling rope 20 can drive the fixed block 21 to move on the scale groove plate 14, so that the usage situation of the raw material in the storage tank 3 can be observed, preventing the device from stopping operation and affecting the working efficiency of the device.

[0020] Working principle: When stirring and preparation are required, the staff can start the second motor 8. The rotation of the output shaft of the second motor 8 drives the feeding wheel 22 to rotate. The rotation of the feeding wheel 22 makes the raw material enter the stirring cylinder 2. Start the first motor 4. The rotation of the output shaft of the first motor 4 drives the gear 5 to rotate. The rotation of the gear 5 drives the toothed plate cover 7 to rotate on the stirring cylinder 2. The rotation of the toothed plate cover 7 makes the fixed rod 17 rotate. The rotation of the fixed rod 17 drives the stirring rod 16 to rotate to stir the raw material. At the same time, the rotation of the toothed plate cover 7 drives the scraper 15 to rotate and scrape the inner wall of the stirring cylinder 2. When discharging, the scraper 15 continues to rotate to scrape off the remaining raw material in the stirring cylinder 2 to prevent waste of raw material;

[0021] Before working, the staff can put the raw material into the storage tank 3 through the feeding port 9. The raw material will accumulate inside the storage tank 3 and squeeze the baffle 23 due to gravity. The baffle 23 slides inside the storage tank 3 under the force and squeezes the spring 24. The spring 24 is stressed and contracts to generate elastic force. At the same time, the sliding of the baffle 23 pulls the pulling rope 20 to be transmitted on the first transmission wheel 12 and the second transmission wheel 13, driving the fixed block 21 at the other end of the pulling rope 20 to move on the scale groove plate 14. During work, under the elastic force of the spring 24, as the raw material decreases, the pulling rope 20 can drive the fixed block 21 to move on the scale groove plate 14, so that the usage situation of the raw material in the storage tank 3 can be observed, preventing the device from stopping operation and affecting the working efficiency of the device.
