[0027] The cleaning mechanism 2 cleans the corn, and the cleaned corn is transported to the rotating drum 43 through the conveying mechanism 3. The gas enters the rotating drum 43 from the air pipe 44 to blow and dry the corn. The clean water adhering to the corn flows out through the water pipe 45. The rotating component 46 drives the rotating drum 43 to rotate, so that the corn rotates and is fully air-dried. The separation and blocking component 47 separates the corn to prevent the corn from piling up.

[0031] The high pressure liquid pump 231 delivers clean water into the water spray pipe 233, and sprays it out through the nozzle to wash the corn.

[0032] As an embodiment of the present invention, please refer to Figures 1 to 5 , the bubbling assembly 24 comprises: The air pump 241 is connected to the cleaning frame 21, and the output end is connected to the air pipe 44; A connection frame 242 is connected to the output end of the air pump 241; The rotating roller 243 is disposed inside the cleaning frame 21 and is rotatably connected thereto. The rotating roller 243 is provided with a plurality of groups of air holes.

[0033] The air pump 241 blows out gas, which is blown out through the air holes on the rotating roller 243 and enters the cleaning frame 21 to generate bubbles. The bubbles burst to generate impact force to clean the corn. At the same time, the driving member 245 cooperates with the transmission component 246 to drive the rotating roller 243 to rotate, ensuring the turbulence of the gas, thereby improving the cleaning effect. The rotating roller 243 drives the bristles 244 to rotate to brush the corn. The driving member 245 can be a stepping motor, a servo motor, etc. The transmission component 246 can be a gear transmission component, a belt transmission component, etc.

[0034] As an embodiment of the present invention, please refer to Figures 1 to 5 , the conveying mechanism 3 comprises: The conveyor belt 31 is rotatably connected to the cleaning frame 21, and a water leakage hole is opened on the conveyor belt 31; Transmission assembly 2 32, one end of which is connected to the conveyor belt 31, and the other end of which is connected to the rotating roller 243; A partition 33 connected to the conveyor belt 31; The discharge port 34 is connected to the bottom plate 1 and is rotatably connected to the conveyor belt 31 . The discharge port 34 extends into the interior of the rotating cylinder 43 .

[0035] The rotating roller 243 drives the conveyor belt 31 to rotate through the transmission component 2 32, and the conveyor belt 31 conveys and lifts the cleaned corn. The partition 33 prevents the corn from sliding down during the lifting process, and the corn lifted to the top rolls down into the rotating cylinder 43 through the discharge port 34. The transmission component 2 32 can be a gear transmission component, a belt transmission component, etc.

[0036] As an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 6 and Figure 7 , the shaking support assembly 41 includes: A fixing sleeve 411 connected to the bottom plate 1; The sliding rod 412 is slidably connected to the fixing sleeve 411, and the top end is connected to the fixing tube 42; The elastic member 413 has a bottom end connected to the bottom plate 1 and a top end connected to the bottom end of the sliding rod 412 .

[0037] The corn falls into the rotating cylinder 43 through the discharge port 34. The impact force generated by the corn falling squeezes the fixed cylinder 42, causing the fixed cylinder 42 to squeeze the elastic member 413 downward. The elastic member 413 undergoes elastic deformation, causing the fixed cylinder 42 to continuously vibrate longitudinally with a small amplitude, causing the moisture adhering to the corn to fall off. The elastic member 413 can be a spring, a shrapnel, etc.

[0038] As an embodiment of the present invention, please refer to Figure 1 , Figure 2 and Figure 6 , the rotating assembly 46 comprises: The second driving member 461 is connected to the fixed cylinder 42; Gear 462 is connected to the output end of the second driving member 461; The gear ring 463 meshes with the gear 462 and is connected to the rotating cylinder 43 .

[0039] The second driving member 461 drives the gear 462 to rotate, the gear 462 drives the gear ring 463 to rotate, and the gear ring 463 drives the rotating cylinder 43 to rotate. The second driving member 461 can be a stepping motor, a servo motor, etc.

[0040] As an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 6 , Figure 8 , Fig. 9 and Fig.10 , the separation and blocking assembly 47 includes: The fixing rod 471 is disposed in the groove and connected to the rotating cylinder 43; A universal sleeve 472 is rotatably connected to the fixed rod 471, a cavity is provided inside the universal sleeve 472, and a plurality of groups of air holes 2 are opened on the universal sleeve 472; A volute spring 473, one end of which is connected to the fixing rod 471, and the other end of which is connected to the universal sleeve 472; The inclined baffle plate 474 is connected to the universal sleeve plate 472 .

[0041] The rotation of the rotating cylinder 43 drives the universal sleeve 472 to rotate, so that the corn rolls between several groups of universal sleeves 472 to prevent the corn from piling up. At the same time, in the process of the rotating cylinder 43 driving the universal sleeve 472 to rotate, the gravity of the corn causes the universal sleeve 472 to rotate around the fixed rod 471, so that the corn rolls on the universal sleeve 472. The inclined baffle 474 blocks the corn to extend the residence time of the corn in the rotating cylinder 43. The airflow blown out by the air pump 241 is blown out through the rotating cylinder 43 and the universal sleeve 472 to blow and dry the corn. The corn is always in a moving state during the drying process to ensure that the corn is fully dried. The setting of the volute spring 473 ensures that the universal sleeve 472 can return to its original state after deflection.

[0042] The working principle of the present invention is as follows: corn is poured into the cleaning frame 21, the high-pressure liquid pump 231 sends clean water into the water spray pipe 233, and the water is sprayed out through the nozzle to wash the corn, the air pump 241 blows out gas, and the gas is blown out through the air holes on the rotating roller 243 and enters the cleaning frame 21 to generate bubbles, and the bubbles burst to generate impact force to clean the corn. At the same time, the driving member 245 cooperates with the transmission component 246 to drive the rotating roller 243 to rotate, so as to ensure the turbulence of the gas, thereby improving the cleaning effect, and the rotating roller 243 drives the brush bristles 244 to rotate to brush the corn; The rotating roller 243 drives the conveyor belt 31 to rotate through the transmission assembly 2 32, and the conveyor belt 31 transports and lifts the cleaned corn. The partition 33 prevents the corn from sliding down during the lifting process. The corn lifted to the top rolls down to the inside of the rotating cylinder 43 through the discharge port 34; The impact force generated by the falling corn squeezes the fixed cylinder 42, so that the fixed cylinder 42 squeezes the elastic member 413 downward, and the elastic member 413 undergoes elastic deformation, so that the fixed cylinder 42 continuously vibrates slightly longitudinally, so that the moisture adhering to the corn falls off. At the same time, the second driving member 461 drives the gear 462 to rotate, the gear 462 drives the gear ring 463 to rotate, the gear ring 463 drives the rotating cylinder 43 to rotate, and the rotating cylinder 43 rotates to drive the universal sleeve plate 472 to rotate, so that the corn rolls between the plurality of sets of universal sleeve plates 472 to avoid To prevent the corns from piling up, at the same time, when the rotating cylinder 43 drives the universal sleeve 472 to rotate, the gravity of the corns causes the universal sleeve 472 to rotate around the fixed rod 471, so that the corns roll on the universal sleeve 472, and the inclined baffle 474 blocks the corns, thereby extending the residence time of the corns in the rotating cylinder 43. The airflow blown out by the air pump 241 is blown out through the rotating cylinder 43 and the universal sleeve 472 to blow and dry the corns. The corns are always in motion during the drying process, thereby ensuring that the corns are fully dried.
