The rice to be screened is poured into the hopper 12 for loading, and the motor 13 is started. The output shaft of the motor 13 drives the synchronous wheel 14 to rotate. The synchronous wheel 14 drives the rotating rod 17 to rotate through the belt 15. The rotation of the rotating rod 17 drives the eccentric rod 18 to produce eccentric rotation. When the eccentric rod 18 rotates, the connecting seat 21 is driven to shake through the base 19. The connecting rod 23 rotates simultaneously with the connecting seat 21, and plays an auxiliary supporting role during shaking through the support block 22.

[0029] A first sieve plate 24 is sleeved inside the connecting seat 21, a second sieve plate 25 is slidably connected inside the connecting seat 21, a collecting box 26 is slidably connected inside the device body 11, and the collecting box 26 is located below the first sieve plate 24.

[0032] Working principle:

[0033] In the first step, the rice to be screened is poured into the hopper 12 for loading, and the motor 13 is started. The output shaft of the motor 13 drives the synchronous wheel 14 to rotate, and the synchronous wheel 14 drives the rotating rod 17 to rotate through the belt 15. The rotation of the rotating rod 17 drives the eccentric rod 18 to produce eccentric rotation. When the eccentric rod 18 rotates, it drives the connecting seat 21 to shake through the base 19. The connecting rod 23 rotates simultaneously with the connecting seat 21, and plays an auxiliary supporting role during shaking through the support block 22. The connecting seat 21 drives the first sieve plate 24 and the second sieve plate 25 of different sizes to screen the rice to screen out the impurities mixed in the rice, and the screened material is transported forward by tilting the connecting seat 21 when it slides. The screened broken rice falls into the collecting box 26, which is convenient for collection and subsequent processing, thereby improving the convenience of using the device and the efficiency of screening.

[0034] In the second step, the rice is shaken by the connecting seat 21 to be screened. During the shaking process, the rice husks that have not been completely husked will float upward. When the motor 13 is started, the belt 15 drives the blade rod 29 to rotate, and the floating rice husks and lighter debris are blown off, so that the rice husks and light debris are screened out more efficiently, which is beneficial to improving the quality of screening. In addition, when the motor 13 drives the rotating rod 17 to rotate for screening, it also drives the blade rod 29 to rotate, without the need for an additional power source, which is beneficial to saving production costs.
