the bottom of the guide pipe 31, so that the servo motor 34 drives the guide pipe 31 to perform reciprocating rotation through the driving gear 35, the gear sleeve 33 and the transmission chain, the diversion pipe 31 rotates to drive the diversion pipe 39 and the high-pressure nozzle 310 at the bottom to rotate, so that the water flow sprayed by the high-pressure nozzle 310 can uniformly wash the rice transported on the first sieve plate 41, when the rice falls on the first sieve plate 41, because the first sieve plate 41 and the second sieve plate 42 are both obliquely arranged, and the first sieve plate 41 and the second sieve plate 42 are connected with the box body 1 through the buffer assembly 43, and the two sides of the fixed plate 432 in the buffer assembly 43 are both provided with the springs 431, so that the first sieve plate 41 and the second sieve plate 42 are not fixedly connected with the box body 1, namely a certain buffer space is arranged between the first sieve plate 41 and the box body 1, a certain buffer space is also arranged between the second sieve plate 42 and the box body 1, the fixed shaft 46 is driven by the driving motor 44 to rotate, the fixed shaft 46 drives the fixed plate 45 and the two fixed rods 47 on the fixed plate 45 to rotate, the two fixing rods 47 are in reciprocating abutting connection with the supporting plates 411 at two sides of the first sieve plate 41 and the second sieve plate 42, so that the first sieve plate 41 and the second sieve plate 42 move up and down, and meanwhile, the first sieve plate 41 and the second sieve plate 42 vibrate in operation by matching with a plurality of springs 431 in the buffer assembly 43, so that the rice passing through the first sieve plate 41 and the second sieve plate 42 is sieved, the first sieve plate 41 and the second sieve plate 42 vibrate, and the first sieve plate 41 and the second sieve plate 42 are both obliquely arranged, so that the rice slowly moves down under the influence of gravity in the vibration process, the first sieve plate 41 intercepts the rice with normal size, and the rice can shake off dust attached to the rice in the vibration process, namely, one-time cleaning of the rice is completed, and meanwhile, the blanking mechanism 3 is matched, can form abluent effect of secondary to the rice, and then form the rice screening simultaneously, the washing effect to the rice has also been reached, when the rice sieves and moves down on first sieve 41, it moves to first sieve 41 one end to polish on first sieve 41, later the rice accessible box 1 on first sieve 41 falls to first collection workbin 12 inside to the discharge gate 11 of first sieve 41 department, the rice accomplishes the screening and washes the back on first sieve 41 in the same way, broken rice, dust and tiny particle impurity fall on second sieve 42, dust and tiny particle impurity can be adulterated in the rivers of washing, pass second sieve 42 and fall into collection case 14, can collect the rivers of washing, tiny particle impurity and dust through collection case 14, broken rice is detained on second sieve 42, in the same way, second sieve 42 is through driving motor 44, fixed disk 45 and dead lever 47's cooperation is used, make when broken rice sieves and moves down on second sieve 42, until the rice one end on the second sieve 42 moves to second sieve 42, the inside collection workbin 13 of second sieve 42 to second sieve 42 of accessible collection workbin 42 on the second sieve 42.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
