[0012] When the electric push rod of the utility model is extended to push the temporary storage bucket to move toward the feeding port, when the temporary storage bucket is aligned with the top plate, the waste concrete blocks can fall into the feeding port through the temporary storage bucket, and then contact the rotating crushing roller through the feeding port to crush the waste concrete blocks. At this time, the entire feeding port is closed by the temporary storage bucket during crushing, so no matter how the waste concrete blocks splash when being torn, no one will be hurt, thereby improving the safety of the device when in use.

[0013] When the temporary storage bucket is aligned with the top plate, the entire crushing bin is in a closed environment except for the discharge port at the lower end during crushing, which can effectively reduce dust to prevent the dust generated by the crushing from being inhaled by the staff, and at this time, water mist can be sprayed through the atomizing nozzle assembly when needed to further reduce the dust generated by the device during crushing.

[0014] The utility model can also play the basic feeding role in the prior art when in use. It only needs to move the temporary storage bin so that half of the temporary storage bin is aligned with the top plate and the other half is misaligned with the top plate. Then, the material can be directly fed into the crushing bin to directly carry out the crushing work. BRIEF DESCRIPTION OF THE DRAWINGS
