[0024] The specific implementation process of the utility model is as follows: when in use, the material is first added into the crushing bin 1 through the feed port 3, and then the handle 5 is pulled up, the handle 5 drives the cover plate 4 to move, the cover plate 4 drives the fixed block 95, the guide rod 96 and the guide block 98 to move, the guide block 98 squeezes the third spring 99, and then the cover plate 4 is rotated to above the feed port 3 and then the cover plate 4 is lowered, and the cover plate 4 can be pressed against the feed port 3 under the elastic action of the third spring 99.

At this time, the gas can be discharged through the feed port 3, thereby achieving the purpose of relieving the pressure inside the crushing bin 1 and preventing the internal air pressure from being too high.
