[0023] Furthermore, in order to facilitate the removal of excess moisture on the inner wall of the transmission belt 4 and avoid affecting the transmission, a reciprocating screw 12 is rotatably provided on the rear side of the inner cavity of the cooling bin 1, and a water absorption plate 14 is provided at the bottom of the reciprocating screw 12 for use with the transmission belt 4.
