[0029] Embodiment 2

[0030] See also Figure 7-9 A wind guide plate 24 is slidably connected to the inner side of the air duct 22, and a convex plate 25 is fixedly installed at the bottom end of the wind guide plate 24. A positioning pin 26 is inserted into the inner side of the convex plate 25, and a tension spring 27 is sleeved on the surface of the positioning pin 26.

[0031] Working principle: When working, first start the motor A4 and drive the shelling cone A5 and gear A29 to rotate. Under the meshing action, it will drive the gear B6 and shelling cone B7 to rotate, so that the husk and grain of the input millet can be separated. The separated grains and husks will fall on the surface of the screen plate 11. Start the motor B8 and drive the transmission rod 9 to rotate. During the rotation of the transmission rod 9, the sliding rod 14 will be driven to slide on the inner side of the sleeve 13 through the connecting plate 30, so that the screen plate 11 can be lifted up along the guide rod 10 for a short distance. Then, as the transmission rod 9 rotates, the sliding rod 14 will be driven to slide down along the sleeve 13 under the action of the connecting plate 30. Under the action of gravity, the screen plate 11 will slide down along the guide rod 10 and squeeze the spring 12. In this way, the screen plate 11 will repeatedly slide up and down a small distance along the guide rod 10, so as to speed up the top of the screen plate 11 During the screening of grains, the motor B8 drives the pulley A15 to rotate while the motor B8 is working, thereby driving the pulley B16 and the threaded rod 18 to rotate through the belt 17. Under the action of the thread, the threaded rod 18 drives the scraper 19 to slide along the body 1, thereby driving the screened grains to be scraped toward the discharge port 3. After the screening work is completed, the baffle 21 is removed by pulling out the pin, and then the hair dryer 23 is started and blown into the body 1 through the air duct 22 to blow out the husks on the sieve plate 11. At the same time, the positioning pin 26 is pulled downward to move it out of the positioning groove 28, and then the convex plate 25 is moved to drive the air guide plate 24 to move. After the position adjustment is completed, the positioning pin 26 is released, and the positioning pin 26 is reset in the adjacent positioning groove 28 under the action of the tension spring 27, so that the airflow can be guided through the air guide plate 24, thereby making it easy to blow out the husks in the corners to prevent residue.
