[0027] Working principle:

[0028] When corn needs to be threshed by dust removal and extrusion:

[0029] Corn threshing stage:

[0030] First, the operator feeds the corn into the main body 1 through the feed port 6, and then connects the external power supply of the first motor 7, starts the first motor 7, and the first motor 7 drives the spiral drum 8 to rotate. The spiral drum 8 threshes the corn, and then the corn cobs and corn kernels fall from the side of the partition 15.

[0031] Dust removal stage:

[0032] When corn cobs and corn kernels pass through the suction fan 4, the external power supply of the suction fan 4 is connected, and the suction fan 4 is started. The suction fan 4 sucks the generated dust into the dust collecting bag 5 through the filter plate. When there are too many corn kernels attached to the filter plate, the operator turns the knob 301, the knob 301 drives the worm 302 to rotate, the worm 302 drives the worm gear 304 to rotate, the worm gear 304 drives the roller 305 to rotate, the roller 305 drives the slider 306 to move, and the slider 306 drives the cleaning roller 307 to move, so as to scrape off the smaller corn kernels on the filter plate, and then the operator stops turning the knob 301.

[0033] Corn cobs and corn kernels classification and discharge stage:

[0034] Corn cobs and corn kernels fall on the screening plate 9, and then the corn kernels fall down on the second baffle 11, and the corn cobs fall onto the first baffle 10. The corn cobs are discharged from the main body 1 through the corn cob outlet 12, and the corn kernels are discharged from the main body 1 through the corn kernel outlet 13. When the screening plate 9 is blocked by the corn cobs, the external power supply of the second motor 202 is connected, and the second motor 202 is started. The second motor 202 drives the incomplete gear 203 to rotate, the incomplete gear 203 drives the gear 204 to rotate, the gear 204 drives the rotating rod 205 to rotate, the rotating rod 205 drives the torque spring 206 to rotate, the torque spring 206 drives the cam 208 to rotate, the cam 208 drives the cross plate 208 to rise, and the cross plate 208 drives the cushion 209 to move, and the screening plate 9 is knocked, so that the corn cobs can move to the first baffle 10 to prevent the corn kernels from being blocked. After that, the second motor 202 stops working, and the dust removal and extrusion threshing of corn is completed.
