Garbage crushing and classifying treatment device for environmental protection engineering

The garbage crushing and classifying treatment device for the environmental protection engineering comprises a supporting column and a convex shell, a main body is installed at the top of the supporting column, a group of crushing bins are installed in the main body, movable grooves are formed in the outer sides of the main body and the crushing bins in a penetrating mode, and the convex shell is installed on one side of the main body in an embedded mode. And a fixing plate is mounted at the top of the main body. The fixing plate is installed and can fix the water pump, when a worker needs to clean the crushing teeth, an external water pipe can be connected from the flange connector, the water pump is started to conduct water suction and drainage work, and water can enter the water pump from the flange connector and flow into the water distribution pipe through the water outlet pipe; and the water is uniformly distributed to each high-pressure spray head by the water distribution pipe, so that the water is sp
