[0026] The air filtration assembly 8 includes: a base 81, a suction filtration motor 82, a housing 83, a wind paddle 84, an air inlet 85, an air outlet 86, a paddle bin 87, a filtration channel 88, a filter plate 89, and a sealing plate 810; the housing 83 is a hollow shell structure, which is fixed on the bracket 1 by the base 81. A wind paddle 84 is rotatably fitted in the housing 83 by a shaft rod. The area where the wind paddle 84 is located is the paddle bin 87. A suction filtration motor 82 is fixed outside the housing 83. The output shaft of the suction filtration motor 82 is fixedly connected to the shaft rod of the wind paddle 84. An opening is formed in the front of the housing 83 in front of the paddle bin 87 to form an air outlet 86. An opening is formed in the side of the housing 83 in the side of the paddle bin 87 to form an air inlet 85. The air inlet 85 is fixedly connected to the suction filtration pipe 7. A filtration channel 88 is provided between the air inlet 85 and the paddle bin 87. The lower part of the filtration channel 88 is fixedly connected to the downward pipe 92.

[0027] In order to intercept the light impurities sucked by the air filtration assembly 8, a filter plate 89 is provided on the side wall of the filtration channel 88. Both sides of the filter plate 89 conduct between the air inlet 85 and the paddle bin 87.

[0028] In order to facilitate the cleaning and maintenance of the filtration channel 88, the side surface of the filtration channel 88 away from the suction filtration motor 82 is a detachable plate-like structure to form a sealing plate 810.

[0029] In order to enable the paddle wheel 5 to have rotational power, the shaft rod 4 connected to the paddle wheel 5 is coaxially fixed to the output shaft of a speed reducer 10. The input shaft of the speed reducer 10 is coaxially fixed to the output shaft of a stirring motor 11. The speed reducer 10 and the stirring motor 11 are fixed on the bracket 1.

[0030] To avoid manual flipping of the flap 6, one side of the flap 6 away from the hinge is hinged to a hydraulic cylinder 12, and the other end of the hydraulic cylinder 12 is hinged to the side wall of the drying chamber 2.

[0031] To facilitate the cleaning of the impurity deposition in the collection box 9, a sealable hatch 91 is provided on the collection box 9. After the sealable hatch 91 is closed, it is in sealed cooperation with the collection box 9.

[0032] To balance the air pressure in the drying chamber 2 during suction filtration and to timely discharge the moisture generated during drying of the corn, an opening is provided on the flap 6, and a flat pressing plate 61 is embedded in the opening. The flat pressing plate 61 is provided with uniformly distributed ventilation holes.

[0033] Brief description of the usage process:

[0034] During use, an external hydraulic control mechanism is connected to the hydraulic cylinder 12, and power supplies with switches are connected to the stirring motor 11, the suction filtration motor 82, and the heating blanket 14.

[0035] First, use the external hydraulic control mechanism to control the hydraulic cylinder 12 to extend. The hydraulic cylinder 12 jacks up the flap 6 to rotate around the hinge to open the flap 6, exposing the upper opening of the drying chamber 2. Then, pour the corn to be dried into the drying chamber 2 through the exposed upper opening. After pouring is completed, use the external hydraulic control mechanism to control the hydraulic cylinder 12 to shorten, and drive the flap 6 again to close the upper opening of the drying chamber 2. At this time, connect the power supplies of the heating blanket 14 and the stirring motor 11. The heating blanket 14 heats the drying chamber 2 to the drying temperature, and the stirring motor 11 drives the shaft rod 4 and the paddle 5 to rotate through the speed reducer 10. The paddle 5 flips and dries the corn in the drying chamber 2.

[0036] After drying is completed, disconnect the power supply of the heating blanket 14 and connect the power supply of the suction filtration motor 82. The suction filtration motor 82 drives the air paddle 84 to pump air from the air inlet 85 to the air outlet 86. A negative pressure is generated at the air inlet 85 and is transmitted to the suction filtration port 21 through the suction filtration pipe 7. After the corn is dried, the corn husk debris, corn cob fragments, and corn membranes on it will separate from the corn. Under the flipping action of the paddle 5, they are lifted because of their light weight and are pumped into the suction filtration pipe 7 under the negative pressure at the suction filtration port 21.

[0037] The suction filtration pipe 7 pumps the impurities such as corn husk debris, corn cob fragments, and corn membranes to the air inlet 85 and is intercepted by the filter plate 89 and accumulates in the filter channel 88. After the impurities in the filter channel 88 are deposited, they enter the downcomer 92 from the filter channel 88 due to gravity and enter the collection box 9 through the downcomer 92 for collection.

[0038] After the corn is dried and cleaned, turn off the power supply of the stirring motor 11 and the suction filtration motor 82, and then open the material discharge port 13. Set a receiving mechanism below the material discharge port 13 to receive the falling corn at the material discharge port 13.

[0039] When the impurities in the collection box 9 accumulate to a certain extent, the sealed bin door 91 can be opened, and then the impurities in the collection box 9 can be cleaned and the sealed bin door 91 can be closed again.

[0040] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
