In the implementation process of the invention, seeds to be dried and screened are poured into a box body from a feed hopper 2, a motor and an air heater are started, one electromagnet is electrified to enable a second fan gear 22 to be meshed with a top adjusting rack 29 or a bottom adjusting rack 25, the motor drives each roller 13 to rotate, in the rotating process of the rollers 13, seeds with granularity smaller than that of screening holes of a first roller 13 fall into the rollers 13 through the screening holes of the first roller 13 and stay on a bearing plate 17, the seeds with granularity larger than that of the screening holes of the first roller 13 are attached to the screening holes of the first roller 13, the first roller 13 rotates to drive the seeds to move until the seeds are ejected under the influence of an arc plate 18 and fall between the first roller 13 and the second roller 13, and the seeds with different granularity are sequentially reciprocated, so that in the process, the second fan gear 22 drives the bearing plate 17 and the arc plate 18 to do small-amplitude reciprocating rotation, thereby driving the seeds on the bearing plate 17 to screen back and forth, so that the seeds are distributed on the bearing plate 17 to roll along the surface of the bearing plate 17 more uniformly and intermittently, the hot air is supplied to the air inlet cavity, the hot air flows upwards to dry the seeds, after the drying is finished, the electromagnet is powered off, the other electromagnet is powered on, thereby driving the bearing plate 17 and the arc plate 18 to do large-amplitude reciprocating swing through the first fan gear 21, the seeds above the bearing plate 17 drop downwards and drop below the roller 13 from the roller 13 under the action of gravity, simultaneously the roller 13 continuously rotates in the process, namely the relative rotation between the roller 13 and the arc plate 18 can extrude the seeds clamped in the screening holes, the screening holes are prevented from being blocked by the seeds, the dried seeds are discharged from the respective discharge hoppers 3, and large particulate matters not screened by the drum 13 are discharged from the discharge hoppers 4, such as blade impurities and the like.
Compared with the prior art, the invention not only can automatically and integrally dry and screen the seeds and reduce the volume and occupied space of equipment, but also effectively solves the problem that in the traditional seed screening process, the seeds are easy to be blocked at the gaps of the screening plates, so that the screening effect is influenced due to the blocking of the screening plates.
The present invention is not limited to the above embodiments, but is capable of modification and variation in detail, and other modifications and variations can be made by those skilled in the art without departing from the scope of the present invention.
