Then the pipe 17 inputs the warm water into the second water tank 15. Next, the water injection port 13 is inserted into the warm water pipe to inject water into the first water tank 12. After the water injection is completed, the raw materials are poured into the feed port 11, and then the raw materials enter the feed bin 1 from the feed port 11 for proportioning. After the proportioning is completed, it is left to stand for a period of time to allow the material to stabilize and reach a constant temperature. Then the push-pull plate 19 is pulled outward. At this time, the proportioning is completed. The finished raw materials enter the mixer 113 through the feed trough 112. After the raw materials enter the mixer 113 through the feed trough 112, the push-pull plate 19 is pushed back to its original position, and then the mixer 113 processes and mixes the raw materials; by injecting warm water into the second water tank 15 and the first water tank 12, a certain degree of thermal insulation control is achieved on the temperature of the raw materials, reducing the possibility that the low temperature caused by low temperature weather will reduce the fluidity of the raw materials, resulting in slow curing, incomplete curing or failure during the material forming and curing process.

After the proportioning is completed, the push-pull plate 19 is pulled outward, and the sliding scraper 2 slides on both sides of the inside of the feed bin 1 to the inner end of the feed bin 1 along the direction of the push-pull plate 19. Then, after the raw materials pass through the feed trough 112 and enter the mixer 113, the push-pull plate 19 is pushed back to its original position. At this time, the sliding scraper 2 slides to its original position on both sides of the inside of the feed bin 1 following the movement of the push-pull plate 19; the sliding scraper 2 slides on both sides of the inside of the feed bin 1 along the direction of the push-pull plate 19, which reduces the waste problem caused by some raw materials adhering to the inner wall of the feed bin 1 in the process of entering the inside of the feed bin 1, resulting in the inability to slide off by themselves.
