[0041] By providing the clamping column 14, the clamping column 14 can be clamped in the corresponding through hole 13 of the installed sub-screen 10, so that the sub-screen 10 can better screen the rice with the vibration of the U-shaped frame 8, thereby improving the stability of the sub-screen 10 when screening rice.

[0042] Working principle:

[0043] When it is necessary to replace and clean the sub-screen 10;

[0044] First, pull the handle 3 to drive the partition 4 to move, and the movement of the partition 4 opens the housing 2 of the white rice grading screen device.

[0045] Secondly, move the clean sub-screen 10 to the corresponding slot 7. When the sub-screen 10 drives the limiting column 12 to move to coincide with the position of the corresponding limiting slot 15, the spring 11 resets and drives the limiting column 12 to move into the inside of the limiting slot 15, and then drives the locking column 14 to move into the inside of the through hole 13.

[0046] Finally, pull the clamping column 14 corresponding to the sub-screen 10 that needs to be replaced and cleaned to move it out of the through hole 13, and then press the button 18 to drive the button body 16 to move, and the button body 16 drives the limiting column 12 to move until it is completely out of the limiting groove 15, and the movement of the limiting column 12 drives the spring 11 to be compressed, and then, pull the sub-screen 10 to move.
