[0019] like Figure 1 As shown, it is a schematic diagram of the structure of the corn seed gravity screening device proposed in the utility model. The screening device of the utility model is provided with a feeding device 100 and a screening device 200. The feeding device 100 is provided with a first support frame 101, a feeding hopper 102 and a lifting machine 103, wherein the feeding hopper 102 and the lifting machine 103 are fixed on the first support frame 101, and the bottom of the feeding hopper 102 is an inclined surface 1020, as shown in FIG. Figure 2 As shown, a feed port 104 is provided on the side at the lowest point of the inclined surface 1020, and the feed hopper 102 is connected to the lifting machine 103 through the feed port 104. The lifting machine 103 is a mechanical equipment used for material handling, which can lift bulk materials vertically or nearly vertically. The manufacturer of the lifting machine 103 in the utility model is Henan Guosai Environmental Protection Equipment Co., Ltd., model AL635417021005. This structure is a prior art and will not be repeated here.

The rotating shaft 106 and the stirring blades 107 are located in the feeding hopper 102. Specifically, a through hole (not marked in the figure) is provided at the bottom of the feeding hopper 102, and the bottom end of the rotating shaft 106 passes through the through hole to be connected with the output shaft of the driving motor 105. In addition, the driving motor 105 is located on the first supporting frame 101. Specifically, a crossbeam frame 1010 is provided on the first supporting frame 101, and the driving motor 105 is located on the crossbeam frame 1010.
