[0055] The guide rollers 133 are pushed to move horizontally by the output end of the electric push rod 1138. The guide rollers 33 on both sides are used to roll and guide the fallen bulky grains so that the rolled bulky grains fall on the conveyor belt 5 for stable transmission.

[0056] The limiting plates 45 are connected by meshing with the gear 139 through the arc-shaped rack 47 at the bottom, so that the two sets of limiting plates 45 rotate around the rotating shaft 43. When the two sets of limiting plates 45 are close to each other, a plurality of sets of screening holes 46 are spliced ​​together to screen the grains during the grain feeding process.

[0057] In the process of driving the rotating shaft 43 to move horizontally back and forth through the output end of the cylinder 42, the two sets of limiting plates 45 are moved horizontally back and forth on the lower surface of the discharge port 22, which is used for vibration in the grain screening process and accelerates the efficiency of grain screening.
