The driving member can be an air cylinder or a hydraulic cylinder, preferably an air cylinder in the technical solution. By controlling the action of the air cylinder, the timing of opening the discharge port can be selected as required. The sealing plate is used to prevent hard materials such as steel bars and iron nails from flying around when they are discharged from the discharge port, causing harm to personnel on site, thereby improving the safety performance of the crushing equipment. The crushing time of building materials can also be controlled through the sealing plate, so as to ensure the crushing effect.

Compared with the prior art, the crushing equipment in the utility model has the following advantages:

1. The crushing equipment in this technical solution is equipped with impact hammers and bevel teeth respectively from top to bottom. After two-stage crushing, the efficiency is improved and the crushing effect is guaranteed.

2. The hitting hammer on the drum in this technical solution is hinged, and under the huge inertia and kinetic energy, it can powerfully hit concrete and other construction wastes and crush them, while for hard materials such as steel bars and iron nails, hitting After the hammer strikes, the counterattack decelerates and changes direction, so as to avoid these hard substances, effectively crush construction waste and effectively protect its own components, and also avoid the rotation cylinder from getting stuck, prolonging the service life.
