Still as shown in Figures 1 and 2, the two ends of the material retaining plate 15 are movably connected on the two side walls of the first opening 14, and each material retaining plate 15 is coaxially connected with a connecting rod, and the upper end of each connecting rod It is movably connected with the first adjusting rod 12, and one end of the first adjusting rod 12 is vertically fixedly connected with a vertical rod, and the vertical rod cooperates with the first fan-shaped adjusting plate 20 fixed on the wall of the blanking tube 2 to slide. Pull the vertical bar to make it slide in the chute of the first fan-shaped adjustment plate 20 to adjust the inclination angle of the material retaining plate 15. When in use, the acute angle between the material retaining plate 15 and the tube wall of the winnowing tube 7 is smaller than the blanking angle. The acute angle formed by the tube 2 and the horizontal plane, in this embodiment, the angle between the blanking tube 2 and the horizontal plane is 50 degrees.

In this embodiment, a row of flaps 16 are movably connected to the second opening 141 along its length direction, and the upper part of the outer surface of each flap 16 is movably connected to the second adjusting rod 19, and one end of the second adjusting rod 19 is fixed vertically. There is a vertical rod, and the vertical rod cooperates with the second fan-shaped adjustment plate 21 fixed on the wall of the material drop tube 2 to slide.
