[0032] Specifically, raw materials are added through the feed pipe 3, and the motor 1 2 and the motor 2 11 are started. The output end of the motor 2 drives the turntable 17 to rotate, and the turntable 17 drives the connecting piece 19 to rotate synchronously. At the same time, under the action of the connecting piece 19, the receiving piece 20 moves up and down, and further drives the moving rod 18 to move up and down. The moving rod 18 drives the screen 13 to move up and down to screen the size of the raw materials. The raw materials with larger particles slide to the outer surfaces of the two crushing rollers 14. At this time, one of the crushing rollers 14 is driven to rotate through the output end of the motor 2 11, and the crushing roller 14 drives one of the gears 15 to rotate, and then through The meshing drives another gear 15 to rotate, and then drives another crushing roller 14 to rotate in the opposite direction to crush the raw materials with larger particles.

[0042] Specifically, the dust in the material box 1 enters the interior of the duct 10 through the dust suction port, and then is transported to the interior of the collection box 8 through the conveying pipe 25. The function of the filter is to prevent the dust from clogging the blower 9.
[0043] Reference Figure 3, the outside of one gear 15 is meshedly connected with the outside of another gear 15 at the corresponding position.
[0044] Specifically, one of the gears 15 drives the other gear 15 to rotate through meshing, so that the two crushing rollers 14 crush the raw materials with larger particles, ensuring that the particle sizes of various materials in the concrete are uniform.

Under the action of the moving rod 18, the screen 13 is driven to move up and down to screen the raw materials. The raw materials with larger particles slide to the outer surface of the two crushing rollers 14. At this time, one of the crushing rollers 14 is driven to rotate through the output end of the motor 2 11, and then the other one is driven under the meshing action of the two gears 15. The two crushing rollers 14 rotate towards each other, and the raw materials with larger particles are crushed by the two crushing rollers 14. One of the crushing rollers 14 drives one of the synchronous wheels 5 to rotate, and then drives the other synchronous wheel 5 to rotate through the belt 6. The synchronous wheel 5 drives the dredging rod 24 to rotate to prevent the raw materials from being blocked when falling. The screen 13 can screen the particles in the raw materials according to their size. The raw materials with larger particles are crushed by the crushing rollers 14 to ensure that the particle sizes of various materials in the concrete are uniform, thereby improving the uniformity and stability of the concrete, and helping to ensure the strength and durability of the concrete.
[0048] In addition, the blower 9 is started to put the interior of the collecting box 8 in a negative pressure state, and then the dust inside the material box 1 is sucked in through the dust suction port. Then, under the action of the duct 10, the dust enters the conveying pipe 25, and the sucked dust is transported to the interior of the collecting box 8 through the conveying pipe 25, and the interior of the material box 1 is dusted. The dust removal can be used to clean up the generated dust in time, reduce dust, protect the surrounding environment, and reduce the impact on air quality and working environment.
