[0015] Furthermore, one end portion of the connecting pipe passes through the lower end surface of the first box body and passes into the interior of the first box body;

[0016] Through the above technical solution, the connecting pipe serves to connect the first box body with the second box body. After the material is filtered in the first box body, the filtered material can be transported to the second box body through the connecting pipe.

[0017] Furthermore, the lower end surface of the second box body is provided with four shock absorbers arranged in a rectangular shape;
