[0026] Here’s how it works:

[0027] First, the new device is placed at the required location and connected to the circuit;

[0028] Second, by adding peanuts to be screened into the feed hopper 31 of the drop control mechanism 3, the electric push rod 363 is controlled to extend, and the push rod end of the electric push rod 363 pushes the second rotating plate 34, so that the second rotating plate 34 rotates around the rotating shaft connected to the first rotating plate 33, and the obstruction of the discharge port of the feed hopper 31 is released, so that the peanuts can fall onto the screening net of the screening device 1 through the discharge port of the feed hopper 31, and the screening of peanut varieties is achieved by controlling the vibration motor of the screening device 1 to operate;

[0029] Third, by controlling the motor 352 to operate, the output end transmission rotating shaft 353 of the motor 352 rotates, the rotating shaft 353 drives the pulley group 354 to rotate, the pulley group 354 drives the transmission shaft 355 to rotate, the transmission shaft 355 drives the first rotating plate 33 to rotate, and at the same time the transmission shaft 355 drives the adjustment structure 36 to rotate, the adjustment structure 36 drives the second rotating plate 34 to rotate, so that the second rotating plate 34 rotates synchronously with the first rotating plate 33, and by controlling the rotation of the first rotating plate 33 and the second rotating plate 34, the size of the discharge port of the feed hopper 31 is adjusted, so as to control the feeding speed of peanuts and avoid the poor screening effect of peanuts caused by the untimely screening of the screening net;

[0030] Fourth, by controlling the electric push rod 363 to retract, the push rod end of the electric push rod 363 drives the connecting rod 3641 of the detection structure 364 to move, and the connecting rod 3641 drives the moving block 3642 to move. The moving block 3642 cooperates with the sliding groove 3643 and the limiting block 3645 through sliding cooperation, so that when the second rotating plate 34 is against the feed hopper 31, the limiting block 3645 squeezes the pressure sensor 3644. When the pressure sensor 3644 is pressurized and the pressure reaches the rated value, the contraction of the electric push rod 363 is stopped, so that it is convenient to detect that the second rotating plate 34 blocks the discharge port of the feed hopper 31.
