The rubber buffer pad 16 is fixedly connected to the bottom of the inner wall of the frame 1. The rubber buffer pad 16 is located below the supporting frame 5. The rubber buffer pad 16 is used to provide protection for the perforated steel plate 10 and the perforated rib plate 11 that fall downward.

[0042] It also includes a wear-resistant rubber lining 17. Two of the wear-resistant rubber linings 17 are fixedly connected to the clamping frame 152. The two wear-resistant rubber linings 17 are symmetrically arranged. The wear-resistant rubber linings 17 are used to enable the clamping frame 152 to clamp the perforated rib 11 more stably.

[0043] The rubber buffer pad 16 can provide buffering when the perforated steel plates 10 and perforated ribs 11 welded together fall downward to increase the safety of the perforated steel plates 10 and perforated ribs 11 when they are discharged.

[0044] The wear-resistant rubber lining 17 can increase the friction between the clamping frame 152 and the perforated rib 11 , thereby improving the stability of the clamping frame 152 when clamping the perforated rib 11 .

[0045] The above is a detailed introduction to the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
