[0002] Concrete, abbreviated as "concrete", is a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates, and water in a certain proportion. The cement concrete obtained by mixing is also called ordinary concrete. It is widely used in civil engineering. The concrete raw materials need to be crushed before use to make the particle size of the concrete raw materials consistent and improve the strength of the concrete.

[0003] The prior art patent document with publication number CN 214716911 U provides a concrete processing device, which adds concrete to be crushed into the gap between the crushing seat and the crushing roller by fixing a crushing seat on the inner wall of the box body and rotating a crushing roller in the crushing seat, and the outer side of the crushing roller is provided with a spiral protrusion in the same direction of rotation as the crushing roller, and drives the crushing roller to rotate by rotating the motor, and the spiral protrusion on the crushing roller rotates to crush the concrete, and drives the concrete to move downward at the same time; thereby achieving crushing and improving the crushing effect. Although the current concrete processing device can crush concrete, it does not have the function of pre-crushing concrete, resulting in that concrete with a larger volume cannot enter the gap between the crushing seat and the crushing roller for crushing, and the practicality is poor.
