[0002] With the continuous acceleration of urbanization, the amount of construction waste is also increasing. Construction waste crushing equipment plays an important role in processing these construction wastes. In the process of crushing and processing construction waste, the construction waste is usually put into the feed hopper to facilitate subsequent crushing and processing in the crushing box. However, in actual operation, due to the uncertainty of the amount of construction waste and the size of the construction waste, it is easy to cause blockage of construction waste in the feed hopper. On the one hand, when the amount of construction waste is large, a large amount of construction waste may accumulate in the feed hopper, exceeding the conveying capacity of the feed hopper, thereby causing blockage.
