The rice will be blown into the rice collecting box 4, while the stones and sand grains of similar size to the rice grains will fall into the sand and gravel collecting box 3, and the stones and sand grains mixed in the rice will be screened out.

[0037] The working principle of the present invention is as follows: when in use, firstly put the rice to be processed into the feed hopper 6, then start the discharge motor 72 to make the connecting rod 76 and the stirring rod 77 stir the rice, and the rice falls into the first screening plate 8 from the gap between the discharge baffle 74 and the discharge hole 63, then start the screening motor 84 on the first screening plate 8, the second screening plate 9 and the third screening plate 10, so that the push rod 86 pushes the rice to move, and the rice is screened, so that the stones and sand grains larger than the rice grains are left in the first screening plate 8, and the rice grains and the stones and sand grains of similar size to the rice grains are left in the second screening plate 9, the stones and sand smaller than rice grains are left in the third screening plate 10, and then the side baffle 89 is raised by the hydraulic rod 88, so that the rice grains, stones and sand grains in the second screening plate 9 are pushed out from the discharge port 810 by the pushing rod 86, and at this time, the rotating motor 22 inside the base 1 is started, so that the turbo fan 23 can generate strong wind, and the wind is guided by the wind guide 24 to the fallen rice grains, stones and sand grains. Since sand and stone are usually heavier than rice, rice will be blown into the rice collection box 4, while stones and sand grains will fall into the sand and gravel collection box 3; through the connecting rod 76 and The stirring rod 77 can ensure that the rice flows out of the discharge hole 63 evenly without clogging or unevenness. The discharge hole 63 and the discharge baffle 74 cooperate to control the discharge amount of the feed hopper 6 to prevent excessive discharge at one time, which may cause the subsequent screening operation to fail to proceed smoothly. The screening holes 83 of different specifications on the first screening plate 8, the second screening plate 9 and the third screening plate 10 can keep stones and sand grains larger than rice grains on the first screening plate 8, rice grains and stones and sand grains of similar size to rice grains on the second screening plate 9, and stones and sand grains smaller than rice grains on the third screening plate 10. 10, preliminary screening is performed, the rice can be pushed to move in the screening plate by the pushing rod 86, the rice is screened, and the rice is discharged from the discharge port 810 by the hydraulic rod 88 and the side baffle 89, and the rice grains and stones and sand grains of similar size to the rice grains can be blown out from the second screening plate 9 by the blower 2, because in the case of equal size, sand and stones are usually heavier than rice, and the rice will be blown into the rice collecting box 4, while the stones and sand grains of similar size to the rice grains will fall into the sand and gravel collecting box 3, and the stones and sand grains mixed in the rice will be screened out.
