Each movable end of the telescopic rod 4 is correspondingly connected with the movable bin body 3, so that the lifting process of the movable bin body 3 is stable and has good synchronicity, the risk of deformation or jamming of the movable bin body 3 is avoided, and the structural stability and service life are ensured.

[0027] In the above setting, the fixed bin body 2 is connected with a conical bottom funnel 8 at the bottom surface; the conical bottom funnel 8 is provided with a discharge conveyor 9 at the bottom. A hot air chamber 10 is arranged in the middle of the fixed bin body 2; the hot air chamber 10 is connected with hot air.
