Document Type and Number:
WIPO Patent Application WO/2022/016967
Kind Code:
A1
Abstract:
A grain charging hopper and a grain dryer having same. The grain charging hopper comprises an inclined pipe (3) for conveying a material. An expandable or contractable airbag layer (14) is provided inside the inclined pipe (3). An inflatable or deflatable auxiliary chamber (13) is formed between the inclined pipe (3) and the airbag layer (14). The surface of the inclined pipe (3) is provided with a gas control unit (4) for inflating or deflating the auxiliary chamber (13) to make the airbag layer (14) expand or contract. When expanding or contracting, the airbag layer (14) can push a material in the inclined pipe (3) to flow downward, so as to avoid the blockage of the material. When falling down, the material in upper lift pots (16) first falls onto rubber baffles (21). The lift pots (16) abut, by means of continuous conveying of a conveyer belt (17), against the rubber baffles (21) to make the rubber baffles (21) incline, such that the material on the rubber baffles falls down stage by stage and is finally discharged out from a discharging port (19).
