[0043] Through the above structure, the utility model provides a multifunctional husk grading screen, which can control the rotation of the adjusting rod 13 as needed, and the adjusting rod 13 drives the partition plate 11 to rotate, and controls the overlapping area size of the arc-shaped discharge hole 14 on the partition plate 11 and the sealing plate 9, thereby adjusting the speed of adding grains into the screen box 5, controlling the impact block 19 to periodically impact the screen box 5, driving the screen box 5 to shake, and the tension spring 20 pulls the screen box 5 to quickly return to the initial position, thereby improving the screening efficiency of the husk, and can also accelerate the separation of the husks in the grains from the grains, and absorb and collect the husks in time after the husks are screened out, so as to avoid the husks from being crowded and blocked above the screen 6, and further improve the screening efficiency of the husks. When used specifically, open the cover plate 10, add a sufficient amount of grains into the feed hopper 8, cover the cover plate 10, control the adjusting rod 13 to move to the middle position of the adjusting slot 12, so that the arc-shaped discharge hole 14 on the sealing plate 9 and the partition plate 11 overlaps half, and performs a medium-speed feeding speed. According to the screening speed of the grains, if the speed needs to be increased, the adjustment is controlled. The rod 13 moves backward to increase the overlapping area of ​​the two arc-shaped feeding holes 14. Conversely, the control rod 13 moves forward to control the motor 17 to run. The motor 17 drives the rotating cylinder 18 and the impact block 19 to rotate. The impact block 19 periodically hits and lifts the screen box 5. The screen box 5 shakes upward and pulls the tension spring 20. When the impact block 19 is separated from the bottom of the screen box 5 due to rotation, the tension spring 20 pulls the screen box 5 to return to the initial position. The shaking of the screen box 5 improves the screening efficiency of the husks, and controls the exhaust fan 22 and the blower. 28 is running, and the blower 28 draws external air to blow toward the grains added into the screen box 5, and blows part of the husks in the grains to the right, so as to facilitate the suction by the suction hood 26. Moreover, under the shaking of the screen box 5, the husks gradually shake to above the grains. Under the blowing of the blower 28, the efficiency of the exhaust fan 22 in extracting the husks is improved, so as to avoid the husks being crowded and blocked on the screen 6, and thus the screening efficiency of the husks is improved. After removing the husks, the grains are screened by multiple screens 6 and then screened into grains of different particle sizes, which are discharged and collected through multiple discharge pipes 7.
