[0031] The mounting plate 5 is connected to the inner wall of the housing 1; a blower 6 is provided on the side of the mounting plate 5; the air inlet end of the blower 6 faces the housing 1; a connecting pipe is provided on the air outlet end of the blower 6, and a plurality of nozzles are provided on the end of the connecting pipe away from the blower 6, and the plurality of nozzles face the direction of the fine filter 12 and the coarse filter 13;

[0032] A rotating motor 10 is provided on the inner wall of the outer shell 1, and a rotating disc 11 with a transmission connection is provided on the output end of the rotating motor 10; the side of the rotating disc 11 is connected to a fine filter 12; the side of the rotating disc 11 is connected to a coarse filter 13; the fine filter 12 and the coarse filter 13 are in a circular ring shape; the diameter of the fine filter 12 is larger than the diameter of the coarse filter 13; the centers of the fine filter 12 and the coarse filter 13 coincide; a plurality of groups of discharge holes 14 are provided on the mounting plate 5; the plurality of groups of discharge holes 14 are arranged on the bottom sides of the fine filter 12 and the coarse filter 13.

[0033] A plurality of heat dissipation windows are arranged on the side of the shell 1, and the plurality of heat dissipation windows are symmetrically distributed on both sides of the shell 1; a rotating door connected in rotation is arranged on the side of the shell 1, and a handle is arranged on the rotating door, and a through hole is arranged on the top of the shell 1; a display screen and a control button are arranged on the controller 2, and the control button is connected to the plurality of discharge parts 7 and the rotating motor 10 for control, and the display screen is connected to the rotating motor 10 for communication; the discharge part 7 includes a connecting bracket, a telescopic rod, a blocking member and a rotating blocking plate, the side of the connecting bracket is connected to the mounting plate 5, the connecting bracket is connected to the telescopic rod, the output end of the telescopic rod is connected to the blocking member, the side of the blocking member is in contact with the side of the rotating blocking plate, and the rotating blocking plate is arranged on the discharge hole 14 on the mounting plate 5 On the side of the position, a rotating shaft is provided on the top of the rotating blocking plate, and the rotating shaft is rotatably connected to the side of the mounting plate 5; a feed pipe 4 is provided on the side of the mounting plate 5, and the top of the feed pipe 4 passes through the outer shell 1, and a feed hopper 3 is provided on the top of the feed pipe 4; a feed hole is provided at the center of the mounting plate 5, and the feed hole is connected to the bottom side of the feed pipe 4; a collecting bucket 8 and a receiving bucket 9 are provided on the bottom of the inner wall of the outer shell 1; the collecting bucket 8 is arranged directly below the multiple groups of discharge parts 7, and the width of the collecting bucket 8 is greater than the width of the discharge part 7, and the receiving bucket 9 is arranged directly below the fine filter screen 12; the width of the receiving bucket 9 is the same as the diameter of the fine filter screen 12; a sealing member is provided on the side of the rotating blocking plate, and the sealing member is in contact and extruded with the side of the discharge hole 14.

[0034] In this embodiment, the efficiency of screening and processing corn kernels can be effectively improved through this device. Compared with traditional devices, this device can achieve a multi-stage screening effect. Raw materials screened to various degrees can be discharged in steps through independent discharge holes 14, avoiding mutual obstruction of the raw materials while achieving accurate classification of raw materials of different particle sizes.

[0035] During the use of the device, the raw materials are poured into the device from the feed hopper 4 at the top. The structure of the feed pipe 3 allows the raw materials to directly enter the internal space of the coarse filter 13. At this time, the rotating motor 10 is started, and the rotating motor 10 drives the turntable 11 to rotate, thereby realizing the synchronous rotation of the coarse filter 13 and the fine filter 12. At this time, the mesh holes of the coarse filter 13 and the fine filter 12 can achieve the effect of screening the corn kernel raw materials.

[0036] When the rotating motor 10 is started, the blower 6 is started at the same time, so that the nozzle can spray high-pressure air. When corn kernels are stuck in the mesh of the coarse filter 13 and the fine filter 12 and rotate to the nozzle position, the corn kernels can be discharged from the mesh through the high-pressure gas, thereby avoiding clogging of the coarse filter 13 and the fine filter 12.

[0037] After a period of rotation and screening, the smallest corn kernels and dust impurities are collected inside the receiving bucket 9, and corn kernels of different sizes are distributed inside the coarse filter 13 and the fine filter 12. At this time, by opening different discharge parts 7, the raw materials inside the coarse filter 13 and the fine filter 12 can be discharged independently. When the telescopic rod retracts inward, there is no contact between the blocking member and the rotating blocking plate. Due to the gravity of the raw materials at the discharge hole 14, the corn kernels will push the rotating blocking plate to open and discharge downward. After the discharge is completed, the rotating blocking plate will automatically close due to its own weight. At this time, the telescopic rod is extended to achieve the closing effect again. By replacing the collecting bucket 8 between opening multiple groups of discharge parts 7, the mixing of corn kernels of various sizes can be avoided, thereby ensuring the accuracy of the screening results.

[0040] The structure with the same spacing can improve the efficiency of clearing blockages of the device and reduce the risk of the filter mesh of the device getting stuck.
