[0041] A specific application of this embodiment is as follows: during use, waste circuit boards are placed into crushing box 1, and the motor is started. The motor drives shaft 1 and a gear to rotate synchronously. Because the two gears are meshed, the two gears rotate, driving the crushing rollers on shaft 1 and shaft 2 in opposite directions, respectively, to crush the waste circuit boards. This arrangement allows for more complete crushing of the waste circuit boards, thereby reducing resource waste. The crushed waste circuit boards then roll down the slope inside crushing box 1 into crushing box 2. Simultaneously, as shaft 2 rotates, it is driven by two pulleys 1 and belt 1, causing shaft 3 to rotate synchronously with shaft 2. As shaft 3 rotates, it drives hammers on it to further crush the crushed waste circuit boards. As the hammers crush the waste circuit boards, a buffer plate inside crushing box 2 cushions the waste circuit boards through two slide bars and springs, ensuring more uniform crushing. The re-crushed waste circuit boards then flow through the lower hopper into the conveying pipe. At the same time, when the rotating shaft three rotates, it will be driven by two pulleys two and belt two, so that the rotating shaft four can rotate synchronously with the rotating shaft three. When the rotating shaft four rotates, it can drive the auger rod and the turbine cutter head to rotate synchronously. When the auger rod rotates, it can transport the waste circuit boards in the conveying pipe to prevent the waste circuit boards from clogging the conveying pipe. The waste circuit boards transported to the crushing filter will be finely crushed again by the rotating turbine cutter head and discharged after being filtered by the crushing filter.
