The end of the spring 7 away from the brush plate 8 is fixedly connected to the inner wall of the thin shell 6. Two guide plates 33 are fixedly connected to the inner wall of the grinding box 18. A collection hopper 24 is provided on the outer side of the screening box 9. A collection bin 25 is provided below the conveying device 1.
[0039] Specifically, guide plate 14 is used to guide the raw material on the conveying device 1 into the screening box 9; guide plate 15 is used to guide the large particles of raw material that have not passed the screening in the screening filter cylinder 13 into the grinding box 18; the collection box 16 is set inside the screening filter cylinder 13 to collect the fine raw material that has passed through the screening filter cylinder 13; the grinding roller 22 is rotatably connected to the inside of the grinding box 18 to grind the large particles of raw material entering the grinding box 18; the screening filter cylinder 13 is rotatably connected to the inside of the screening box 9 to perform screening operations on the raw material; one end of spring 7 is fixed to the inner wall of the thin shell 6 to provide elasticity so that the brush plate 8 fits tightly against the surface of the conveying device 1 to ensure the cleaning effect; guide plate 23 is fixed to the inner wall of the grinding box 18 to guide the ground raw material to the collection hopper 24; the collection hopper 24 is set outside the screening box 9 to collect the raw material after screening and grinding; the collection bin 25 is set below the conveying device 1 to collect the raw material scattered during the conveying process.
[0040] Working principle: When in use, the drive motor 3 works, and the conveyor 1 can transport the raw materials required for concrete processing, transporting the raw materials required for concrete production from one place to another, thus starting the entire production process.
[0041] The cleaning assembly on the outside of the conveying device 1 is used to keep the surface of the conveying device 1 clean and avoid material residue affecting the conveying efficiency and equipment life. The electric push rod 4 is installed on the connecting plate 2 and pushes the fixing block 5 through the output end, so that the thin shell 6 fixed between the two fixing blocks 5 moves. The brush plate 8 inside the thin shell 6 is in close contact with the surface of the conveying device 1 by means of the elastic force of the spring 7.

After the motor 11 on the support frame 10 is started, its output end drives the synchronous wheel 12 to rotate. Since the screening filter cylinder 13 is fixedly connected to the outside of the synchronous wheel 12, the screening filter cylinder 13 will rotate inside the screening box 9. During the rotation, the fine raw material will fall through the screening filter cylinder 13 into the collection box 16 inside it. The inclined plate 17 on the bottom wall of the collection box 16 will guide these fine raw materials to flow towards the collection hopper 24.
[0043] Large particles of raw material that do not pass through the screening filter cylinder 13 will enter the grinding chamber 18 under the guidance of the guide plate 2 15. The synchronous wheel 1 12 drives the synchronous wheel 20 to rotate through the synchronous belt. The synchronous wheel 20 is fixed to the outside of one of the grinding rollers 22, so the grinding roller 22 will rotate accordingly. Since the gears 21 on the outside of the two grinding rollers 22 mesh with each other, the other grinding roller 22 will rotate in the opposite direction. The two grinding rollers 22 rotate in opposite directions to grind the large particles of raw material entering the grinding chamber 18. The inclined plate 2 19 on the bottom wall of the grinding chamber 18 and the two guide plates 3 23 on the inner wall will guide the ground raw material to flow to the collection hopper 24 outside the screening box 9 for collection and utilization.
