The working principle is as follows: when the grain-separating machine is used, the motor 21 rotates anticlockwise to drive the rotating shaft I20 to rotate, the rotating shaft I20 rotates to enable the arc-shaped lug I18 on the outer side to rotate around the rotating shaft I20 continuously, because the shortest distance between the rotating shaft I20 and the sliding block I13 is smaller than the length of the arc-shaped lug I18, when the arc-shaped lug I18 moves to the bottom of the rotating shaft I20 around the rotating shaft I20, the sliding block I13 is pushed to move downwards, and when the sliding block I13 moves downwards, one end of the clip-shaped frame 23 is inclined towards one side of the discharge pipe II 24 through the hinge rod 6, when the arc-shaped lug I18 moves to other positions of the rotating shaft I20 around the rotating shaft I20, the sliding block I13 moves upwards under the acting force of the return spring 7, the clip-shaped frame 23 is reset through the hinge rod 6, namely when the output end of the motor 21 rotates, the two ends of the clip-shaped frame 23 can be driven to deflect continuously to enable grains on the screen 25 on the inner side of the clip-shaped frame 23 to move left and right continuously, in the process of moving grains left and right, the grains enter the bottom of the circular shell 5 through the aperture of the screen and are discharged from the discharge pipe I1, impurities are left at the top of the screen 28, the grains are continuously moved left and right at the top of the screen 28 to roll, the grain screening efficiency is improved, meanwhile, when the output end of the motor 21 drives the rotating shaft I20 to rotate reversely, the rotating shaft II 11 is driven to rotate clockwise through the cooperation of the gear I19 and the gear II 15 of the rotating shaft I20, when the rotating shaft II 11 rotates clockwise, the arc-shaped lug II 14 on the outer side of the rotating shaft II is continuously rotated around the rotating shaft II 11, because the radius one third of the radius of the gear II 15 is larger than the radius of the gear I19, the rotating speeds of the rotating shaft I20 and the rotating shaft II 11 are different, namely, the rotating shaft I20 drives the arc-shaped lug I18 to rotate for a plurality of circles, the rotating shaft II 11 drives the arc-shaped lug II 14 to rotate for one circle, when the rotating shaft II 11 drives the arc-shaped lug II 20 to move to the lower part, because the shortest distance between the second rotating shaft 11 and the sliding block 13 is less than the length of the second arc-shaped projection 14, and the difference between the second arc-shaped projection 14 and the shortest distances between the second arc-shaped projection 11 and the sliding block 13 is greater than the difference between the first arc-shaped projection 18 and the first rotating shaft 20, the sliding block 13 is pushed by the second arc-shaped projection 14 to move downwards for a greater distance, one end of the clip frame 23 is moved to the bottom end of the discharge pipe 24 through the hinge rod 6, at this time, under the action of gravity, the impurities are discharged from the discharge pipe 24, the automatic discharging function is realized, when the second arc-shaped projection 14 is driven by the second rotating shaft 11 to continue rotating, the sliding block 13 moves upwards under the action of the return spring 7, when the hinge rod 6 moves the clip frame 23 upwards to the position above the discharge pipe 24, the arc-shaped opening 101 of the circular material blocking plate 10 at one end of the second rotating shaft 11 moves to the discharge port 9, at this time, the grain in the hopper enters the screen 25 in the cylindrical shell 5 from the discharge port 9 to realize the automatic feeding function, and during the sieving, the square frame 23 deflects left and right to make the fixed shafts 26 on both sides rotate continuously, and the fixed shafts 26 rotate continuously and positively and negatively to drive the piston rods 29 to move continuously and vertically through the gear 27 at one end thereof in cooperation with the rack 28, when the piston rods 29 move downwards, the piston 30 can be driven to move downwards in the dust suction tube 35 to generate negative pressure in the dust suction tube 35, at this time, the sealing plate 38 at the position of the air inlet 32 can overcome the acting force of the torsion spring 39 to rotate downwards to open the air inlet 32, so that the dust generated during the sieving in the cylindrical shell 5 can be sucked into the dust suction tube 35 through the dust suction hood 31 and the air inlet pipe 33, and when the piston rods 29 move upwards, further, a positive pressure is generated inside the dust suction tube 35, at this time, the sealing plate 38 at the position of the air outlet 37 rotates upward against the action force of the torsion spring 39 to open the air outlet 37, and the air is discharged, and the dust filtering net 41 disposed inside the air outlet 37 can prevent the dust from being discharged.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
