When the drying degree of the raw materials is detected to meet the requirement, the rotating wheel 643 rotates to drive the material baffle 63 to move to the side, far away from the door main body 2, of the material discharge pipe 62, the raw materials in the bin body 1 can be discharged sequentially through the material discharge pipe 61 and the material discharge pipe 62, the discharging can be completed without opening the door main body 2, the door main body 2 does not need to be opened, the labor intensity of workers is reduced, and the production efficiency of the dryer is improved; meanwhile, after the blanking is completed, the rotating wheel 643 is rotated to drive the striker plate 63 to block the blanking hole 27, so as to block the raw material. When the jam phenomenon appears in unloading pipe 61 or discharging pipe 62 in the raw materials, open locking Assembly 56, then dismantle flitch 72, can use the instrument to dredge unloading pipe 61 or discharging pipe 62, the mediation is accomplished the back, install flitch 72 on leading to pipe 7, close locking Assembly 56, consequently need not to open door main part 2 and dredge unloading pipe 61 or discharging pipe 62, with this time saved, the production efficiency of desiccator has been improved.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
