One end of the inlet adjusting plate 5 is hinged to the shell 1. The shell 1 is provided with an inlet adjusting screw 6 opposite to the inlet adjusting plate 5. The seed outlet 3 is provided with an outlet adjusting plate 7. One end of the outlet adjusting plate 7 is hinged to the shell 1. The shell 1 is provided with an outlet adjusting screw 8 opposite to the outlet adjusting plate 7. The two sides of the shell 1 are provided with connecting lugs 4. The connecting lugs 4 are used for connecting the front shell and the rear shell.
[0021] Please refer to Figures 1-3 The middle of the shell 1 is provided with the seed plate 9. The seed plate 9 is provided with a shaft body 11 in the middle. The shaft body 11 is provided with a bearing 12. The bearing 12 is provided with a suction hole adjusting disc 10. The suction hole adjusting disc positioning assembly 14 is arranged above the suction hole adjusting disc 10 and is fixedly connected to the seed plate 9. The seed plate 9 and the suction hole adjusting disc 10 are both provided with a plurality of suction holes 13 of equal size in the form of a ring. The number of the suction holes 13 on the seed plate 9 is equal to that on the suction hole adjusting disc 10 and is arranged in front of and behind the suction holes 13 on the suction hole adjusting disc 10. This design is to adjust the effective suction area of the suction holes 13 by cooperation of the front and rear suction holes 13.
