The seeds fall on the feeding plate 412. Since the two screening plates 406 and the feeding plate 412 are set at an inclined angle, the seeds on them can be transported to the outside of the three discharge ports 3 and fall on the conveying component 7. When two of the connecting gears 409 rotate, the six T-shaped columns 408 will be driven to rotate synchronously, and the four connecting columns 410 and cams 411 connected thereto will rotate synchronously, and the four cams 411 will hit the connecting plate 407, and the seeds will be poured into the feeding shell 502. With the cooperation of the quantitative member 504, the seeds will be loaded into the feeding shell 502, and the limiting column 503 will be rotated to drive the quantitative member 504 to load the seeds into the feeding shell 502. When the measuring piece 504 rotates, the seeds will be poured quantitatively from the feed port 501 onto the screening plate 406, thereby quantitatively feeding the seeds. By rotating the limiting column 503, the two driving gears 601 will be driven to rotate, and the two toothed belts 603 are the connection hubs of the two driving gears 1 601 and the driving gear 2 602, so that they rotate synchronously and drive the connecting column 410 connected to the driving gear 2 602 to rotate. The motor 605 is stably supported by the mounting frame 604, and the motor 605 is started to drive the driving gear 1 601 connected thereto to rotate, and the limiting column 503 and the other driving gear 1 601 rotate synchronously.
