[0022] The base 1 is placed horizontally on the ground, and then the driving motor is connected to the driver 2, and the driving motor is turned on, so that the driver 2 runs and drives the crushing box 3 to run. When the rubber is recycled, the rubber needs to be crushed. The rubber to be crushed is poured into the silo 4, and then falls into the crushing box 3 through the silo 4 and is crushed by the crushing box 3.
