Material crusher capable of preventing dust raising

The invention relates to the technical field of material crushing, in particular to a material crusher capable of preventing dust raising. The material pulverizer capable of preventing dust raising comprises a discharging pipe, a telescopic pipe, a winch, a pull rope and a dust raising preventing mechanism, the telescopic pipe communicates with the discharging pipe, the telescopic pipe can stretch out and draw back so that pulverized solid waste can be tightly attached to a material pile to be discharged, the pull rope is wound around a winding wheel of the winch, and the dust raising preventing mechanism is arranged on the winding wheel of the winch. The lower ends of the pull ropes are connected with the outer wall of the telescopic pipe to drive the telescopic pipe to stretch out and draw back. When the telescopic pipe extends, the bottom end of the telescopic pipe can make contact with a vehicle hopper of a transport vehicle, when smashed solid waste falls down through the telescopic pipe to be discharged
