The body 11 has a working chamber 12 inside for placing the cantilever 15, the first segment 21 and the second segment 22, etc.
The input end 13 is located on the top surface of the main body 11 and is communicated with the working cavity 12, the output end 14 is located on the bottom surface of the main body 11 and is communicated with the working cavity 12, and in the working process, waste concrete flows in from the input end 13 and flows out from the output end 14 after being extruded and crushed by the first sector 21 and the second sector 22.
Two cantilevers 15 are installed in the working chamber 12, and both ends of each cantilever are fixedly connected with the inner wall of the adjacent working chamber 12. The two cantilevers 15 are arranged horizontally and parallel to each other.
The first segment 21 and the second segment 22 are mounted on the two booms 15, respectively. The first segment 21 has two segment planes, two rectangular planes and a curved surface, which is called the working curved surface of the first segment 21, and the structure of the second segment 22 is the same as that of the first segment 21, and will not be described herein.
In the working process, the waste concrete flows between the working curved surface of the first fan-shaped body 21 and the working curved surface of the second fan-shaped body 22, and flows out from the output end 14 after being extruded and crushed.
A first concave-convex portion 23 is provided on the working curved surface of the first segment 21, a second concave-convex portion 24 is provided on the working curved surface of the second segment 22, and the first concave-convex portion 23 and the second concave-convex portion 24 are matched with a gap therebetween.
