S5, the waste falls onto a conveying belt of the drying box, the conveying belt drives the waste to move, the driving roller drives the first rotating disc to rotate through the second conveying belt and the third conveying belt, the first rotating disc drives the mounting rod to swing back and forth through the eccentric pin and the second sliding groove, and the mounting rod drives the upper air nozzle to swing back and forth to dry the waste; blow-drying the waste from the lower part of the waste by a blow-down nozzle;

S6, the dried waste is moved out of the drying box through an outlet, the driven roller drives the second rotary table to rotate through a fourth driving belt and a second driving wheel, the second rotary table drives the driving rod to swing back and forth through the fixing column and the third sliding chute, the driving rod drives the sector gear to swing, the sector gear drives the compression rod to lift back and forth through the second rack, the compression rod drives the compression plate to move up and down, and the waste is compressed under the action of the compression plate and the fixing plate;

s7, enabling the compressed waste to fall into a lifting machine, enabling the waste to enter a crusher for crushing through the lifting machine, enabling the crushed reclaimed materials to enter a equalizing pipe through a feeding pipe, enabling the reclaimed materials to enter a hopper through a branch pipe, enabling a second air tap in the hopper to blow air to the center of the hopper, and mixing the reclaimed materials with new materials.
