The screening plate 16 is installed inside the screening chamber 4. The material storage plates 17 are installed at both ends of the screening plate 16. The material storage plates 17 extend to the outside of the screening chamber 4. The inner wall of the material storage plate 17 is installed with a telescopic spring 18. The top of the telescopic spring 18 is connected to the bottom of the material storage plate 17. The screening plate 16 is designed to be an upwardly protruding arc. The screening plate 16 can efficiently screen and process the water reducer. The transmission structure includes a fixed seat 19, a third servo motor 20 and an eccentric wheel 21. The fixed seat 19 is installed on both sides of the screening chamber 4. The eccentric wheel 21 is installed on the inner side of the fixed seat 19, and the third servo motor 20 is installed on the outer side of the fixed seat 19. The output end of the third servo motor 20 is connected to one end of the eccentric wheel 21. When in use, the water reducer enters the interior of the screening chamber 4 through the discharge port 3. At this time, the third servo motor 20 is started to drive the eccentric wheel 21 to rotate, so under the cooperation of the telescopic spring 18, the screening plate 16 and the storage plate 17 are driven to shake up and down to screen the water reducer. The water reducer that has not passed the screening plate 16 rolls down the screening plate 16 to the storage plate 17 for discharge, and the qualified water reducer falls into the bottom of the screening chamber 4. The ground water reducer can be screened and the unground water reducer can be screened out so that it will not be fed into the interior of the concrete, so it will not affect the quality of the concrete, thereby greatly improving the practicability of the device when in use.

[0021] The grinding mechanism includes a grinding chamber 7, a grinding disc 8, a first servo motor 9 and a rotating structure. The grinding chamber 7 is installed inside the grinding box 1. A grinding disc 8 is arranged above the grinding chamber 7. The first servo motor 9 is installed at the top of the grinding box 1. The output end of the first servo motor 9 is connected to the top of the grinding disc 8. The side of the grinding disc 8 is designed to be inclined. The rotating structure includes a transmission gear ring 10, a mounting seat 11, a second servo motor 12, a driving gear 13 and a limiting groove 14. The transmission gear ring 10 is installed on the outer side wall of the grinding chamber 7. The mounting seat 11 is installed outside the grinding box 1. The second servo motor 12 is installed on the top of the mounting seat 11. The driving gear 13 is installed inside the mounting seat 11. The output end of the second servo motor 12 is connected to one end of the driving gear 13. One side of the driving gear 13 is connected to the transmission gear ring 1 0 is meshed with each other, the driving gear 13 is opened at the lower part of the grinding box 1, and a limiting groove 14 is arranged inside the driving gear 13. The top of the limiting groove 14 is connected to the bottom end of the grinding chamber 7. When in use, the water reducer is placed into the grinding box 1 from the feed port 2. At this time, the water reducer enters the grinding chamber 7. At this time, the first servo motor 9 is started to drive the grinding disc 8 to rotate, and the grinding chamber 7 and the grinding disc 8 are used to grind the water reducer, and then the second servo motor 12 is started to drive the driving gear 13 to rotate. Since the driving gear 13 and the transmission gear ring 10 are meshed with each other, the transmission gear ring 10 is used to drive the grinding chamber 7 to rotate under the limitation of the limiting groove 14 and the limiting block 15, so that the rotation direction of the grinding chamber 7 and the grinding disc 8 is opposite, so that the grinding effect of the water reducer is better, the water reducer is broken up, and the use effect of the water reducer is better.

[0022] The inner diameter of the limiting groove 14 is larger than the outer diameter of the limiting block 15, and a sliding structure is formed between the limiting groove 14 and the limiting block 15. When in use, the limiting groove 14 and the limiting block 15 cooperate with each other to limit the grinding chamber 7 during rotation, so that the grinding chamber 7 is more stable during rotation.

[0023] Working principle: The staff first puts the water reducing agent into the grinding box 1 from the feed port 2. At this time, the water reducing agent enters the grinding chamber 7. At this time, the first servo motor 9 is started to drive the grinding disc 8 to rotate, and the grinding chamber 7 and the grinding disc 8 are used to grind the water reducing agent. Then the second servo motor 12 is started to drive the driving gear 13 to rotate. Since the driving gear 13 and the transmission gear ring 10 are meshed with each other, the grinding chamber 7 is driven to rotate by the transmission gear ring 10 under the limit of the limit groove 14 and the limit block 15, so that the rotation of the grinding chamber 7 and the grinding disc 8 is smooth. The moving direction is opposite, so the grinding effect of the water reducer is better, and then the water reducer enters the interior of the screening chamber 4 through the discharge port 3. At this time, the third servo motor 20 is started to drive the eccentric wheel 21 to rotate, so under the cooperation of the telescopic spring 18, the screening plate 16 and the storage plate 17 are driven to shake up and down to screen the water reducer. The water reducer that has not passed the screening plate 16 rolls down the screening plate 16 to the storage plate 17 for discharge, and the qualified water reducer falls into the bottom of the screening chamber 4, and then the screw conveyor 6 is used to transport the water reducer to feed the water reducer.
