[0046] Working principle:

[0047] When the rice production with the grain and chaff separator is used to screen and separate the grain and chaff mixture, a receiving container can be placed below the bottom opening of the box 1 in advance, the running motor 301, the first forward and reverse motor 501, the second forward and reverse motor 505 and the vibration motor 604 are controlled through the control terminal 4, then the grain and chaff mixture is added to the inside of the box 1 through the filling port 101, due to the blocking of the funnel groove 302, the added grain and chaff mixture will be stored in the inside and the space above the funnel groove 302 in advance;

[0048] The motor 301 drives the transmission rod 303 to rotate and drives the spiral auger blade 304 to rotate, the grain and chaff mixture falling in the funnel groove 302 is continuously driven to move by the spiral auger blade 304 in a certain amount, and is downwardly conveyed into the inside of the conveying flexible hose 306 through the feed pipe 305, the grain and chaff mixture added and separated can be controlled and conveyed through the controlled amount conveying assembly 3 arranged, so as to avoid that too much is added at one time and increase the difficulty of screening and separation;

[0049] Due to the first positive and negative motor 501 drives the first threaded rod 503 to rotate in the positive and negative directions, the moving frame 504 moves back and forth with the help of the first slide rod 502 and the first threaded rod 503, and the second positive and negative motor 505 drives the second threaded rod 506 to rotate in the positive and negative directions, and at the same time, the second slide rod 507 drives the moving seat 508 to move back and forth, and through the synchronous operation of the two, the moving seat 508 moves along a plurality of S-shaped operation tracks, thereby driving the conveying flexible hose 306 to move synchronously, and the millet mixture conveyed into the conveying flexible hose 306 is evenly distributed and spread in the inside of the screening frame 7, and the U-shaped frame 601 drives the screening frame 7 to vibrate repeatedly through the operation of the vibration motor 604 and the cooperation of the plurality of first springs 603, so that the millet mixture in the screening frame 7 is screened and separated, the rough rice is screened out through the screen holes in the inside of the screening frame 7 and flows into the storage container placed below through the opening at the bottom of the box 1, and the chaff remains in the inside of the screening frame 7.

[0050] Through the cooperation of the above structure, the quantity of the millet mixture to be separated can be controlled, the difficulty of vibrating screening separation is avoided due to excessive feeding, and the conveying flexible hose 306 moves along a plurality of S-shaped operation tracks through the moving assembly 5, thereby increasing the distribution range of the millet mixture and making the distribution more uniform, so as to avoid the influence of the small distribution range on the vibrating screening separation effect.

[0051] When the operation is completed, the protective door 2 is opened, two people cooperate to move the sliding block 804 to one side and stretch the second spring 805 by driving the two sides of the driving plate 806, at this time, the limiting block 807 moves to the inside of the storage groove 808 along with the sliding block 804, thereby being separated from the limiting groove 703 to release the limitation of the U-shaped fixed plate 702 on the screening frame 7, at this time, the screening frame 7 can be pulled out by pulling the handle 701, when the screening frame 7 is put in again, the above operation is repeated, and after the U-shaped fixed plate 702 on the surface of the screening frame 7 is inserted into the U-shaped groove 602, then the driving plate 806 is released, the second spring 805 is reset to drive the limiting block 807 to move and insert into the limiting groove 703 to fix the U-shaped fixed plate 702, thereby completing the stabilization of the screening frame 7, and through the above-mentioned mode, the screening frame 7 is convenient to take out or replace.

[0052] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms, any skilled person in the art can modify or change the above-mentioned technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification made to the above-mentioned embodiments according to the technical essence of the present application still belongs to the protection scope of the technical scheme of the present application.
