Working principle:
When the invention is used, wheat seeds are put into the screen frame 2, the motor 7 is started to drive the eccentric wheel rod 6 to rotate, the screen frame 2 is extruded once after the eccentric wheel rod 6 rotates for one circle, the screen frame 2 drives the guide rod 4 to move downwards on the frame plate 3, the spring 5 is compressed, when the eccentric wheel rod 6 rotates for one circle, the spring 5 drives the screen frame 2 and the guide rod 4 to ascend and reset, and the like repeatedly, so that the continuous up-and-down vibration of the screen frame 2 is realized, the screening and removal of impurities in the seeds in the screen frame 2 are facilitated, the bevel gear II 16 is driven to rotate when the eccentric wheel rod 6 rotates, the bevel gear I14 is driven to rotate by the bevel gear II, the square telescopic rod shaft 13 is driven to rotate by the bevel gear I14, the square telescopic rod shaft 13 is driven to rotate by the scraper 17, the scraper 17 is favorable for scraping impurities blocked in the screen holes in the screen frame 2, the impurities are directly screened and dropped from the screen holes, or the impurities in the sieve holes can be scraped in the sieve frame 2 again, wait to enter other sieve holes again for sieving, the blocking of the sieve holes is avoided, the sieving quality is ensured, the square telescopic rod shaft 13 is arranged to adaptively adjust and stretch according to the up-and-down motion of the sieve frame 2, thereby ensuring that the square telescopic rod shaft 13 normally drives the scraping plate 17 to rotate, the normal up-and-down motion of the sieve frame 2 is not influenced, the scraping plate 17 is convenient for scraping the wheat seeds in the sieve frame 2 in a horizontal plane, the vertical vibration of the sieve frame 2 is matched with the up-and-down vibration of the sieve frame 2, the blocking of the sieve frame 2 is effectively prevented, the air bag 22 is intermittently extruded when the sieve frame 2 vibrates up and down, the air in the air bag 22 is sprayed out from the spray pipe 21, so that the light impurities in the vibrated wheat seeds are blown to the discharge groove 24 opposite to the vibration when the sieve frame 2 vibrates up and down, impurities can be screened out of the screen frame 2 and can be discharged from the discharge groove 24, screening impurities in various modes can be realized, screening efficiency of impurities in wheat seeds can be improved, the provided splash guard 23 can prevent the condition that the wheat seeds are blown out of the screen frame 2 when the wind force of the spray pipe 21 is large, when the screen frame 2 vibrates up and down, the cleaning sheet 25 and the connecting rod 26 are fixed with the frame plate 3, so that the cleaning sheet 25 moves up and down in the discharge groove 24, cleaning of the impurities blocked in the discharge groove 24 is facilitated, smoothness in the discharge groove 24 is ensured, when the scraper 17 rotates, the lifting blade shaft 18 drives the transmission gear 19 to synchronously rotate, when the transmission gear 19 rotates to be contacted with the rack 20, the transmission gear 19 is meshed with the rack 20, and the transmission gear 19 and the lifting blade shaft 18 are further driven to rotate, the intermittent rapid rotation of the lifting blade shaft 18 is beneficial to lifting wheat seeds in the screen frame 2, not only can prevent a large amount of wheat seeds from accumulating together and causing the condition that impurities are difficult to screen, but also can be matched with the spray pipe 21 to spray the impurities in the lifted wheat seeds to the direction of the discharge groove 24, and is beneficial to removing the impurities, when the impurities of the wheat seeds in the screen frame 2 are screened, only the worm 10 is required to be rotated to drive the worm wheel 9 to rotate, the worm wheel 9 drives the rotating shaft 8 to rotate, the rotating shaft 8 drives the frame plate 3 to rotate, the frame plate 3 drives the guide rod 4 and the screen frame 2 to integrally rotate and incline, the screen frame 2 drives the baffle 28 to synchronously rotate, the movable rod 32 is pulled outwards to drive the shielding plate 31 to outwards, when the lower end of the baffle 28 is contacted with the triggering rod 30, the triggering rod 30 can squeeze the baffle 28, so that the baffle 28 slides on the screen frame 2, with discharge gate 27 open, the wheat seed in the reel 2 can drop under the effect of gravity in baffle 29, enter into next level by baffle 29 again and detect, easy operation, convenient to use, when the sunshade 31 of setting prevents not empting the wheat seed, impurity falls in the baffle 29, protruding pole 11 and the spacing 12 of setting can restrict the turned angle of reel 2, the angle of reel 2 is not proofreaded to the manual work, be favorable to the operation, be provided with magnet between baffle 28 lower extreme and the reel 2, the condition that baffle 28 was opened discharge gate 27 when can avoid reel 2 to shake from top to bottom.
