[0030] The rear end of the screening box 1 is inclinedly connected with a transmission cylinder 110 to facilitate the upward feeding of the transmission cylinder 110. A spiral auger 113 is connected inside the transmission cylinder 110 through a bearing. A second motor 112 is installed at the top of the transmission cylinder 110, and the output end of the second motor 112 is connected with the spiral auger 113.
