8. The working method of the embryo-grain separation device for rice processing as claimed in claim 1, wherein the working method comprises the following steps:

the method comprises the following steps: pouring rice embryo grains needing to be screened into the feeding funnel (2), starting the push rod motor (6), enabling the push rod motor (6) to drive the rack (27) to move, enabling the rack (27) to drive the annular plate (34) to rotate due to the meshing connection of the rack (27) and the gear teeth (28), enabling the connecting rod (29) to rotate along with the rotation of the annular plate (34) due to the fact that one end of the connecting rod (29) is rotatably connected with the fixed column (30) through a bearing, enabling the connecting rod (29) to rotate with the limiting column (31) as an original point after the connecting rod (29) rotates, enabling the gap between the limiting plates (33) which are arranged at equal angles to be increased, and adjusting the feeding speed of the feeding funnel (2);

step two: when the rice embryo grains enter the processing tank (26) from the discharging hopper, the rice embryo grains freely fall under the influence of gravity, the first fan (8) starts to work to separate the rice embryo grains for the first time, and because the separated types in the rice embryo grains have different weights and the weight of impurities is small, the first fan (8) operates to suck the unwanted impurities into the first collecting box (3), and the rest rice embryo grains fall into the separating tank (16);

step three: the driving motor (43) is started, the driving motor (43) drives the fixed shaft (15) to rotate, the fixed shaft (15) drives the sleeve (7) to rotate, the rotating rod (5) and the fixed block (10) rotate simultaneously, when the fixed block (10) moves to the lowest end of the separation groove (16), rice embryo grains are stored in the groove (11), when the fixed block (10) moves to the highest point, due to the action of inertia, the rice embryo grains move out of the groove (11) from the groove (11) at an initial speed, the rice embryo grains do parabolic motion in the air, the third fan (24) separates the rice embryo grains, impurities are blown into the separation groove (16), the rest rice embryo grains move onto screening meshes, the rice embryo grains roll above the screening meshes, and enter the blanking groove (17) through the screening meshes;

step four: after the rice embryo granules enter the blanking groove (17), the rice embryo granules do free falling motion, the second fan is started to suck impurities into the second collection box (23), so that the rice embryo granules are separated for the third time, and the rest rice embryo granules enter the blanking drawer (19);

step five: when the third fan (24) needs to be disassembled, the third fan (24) is pushed to move towards the processing tank (26), thereby the limit block (38) is contacted with the side wall of the clamping groove (39), the limit block (38) is forced to move towards the limit groove (41), thereby relieving the limit between the limit block (38) and the clamping groove (39), the sliding block (37) slides in the first sliding groove (36), when the slide block (37) moves to the bottom end of the first sliding chute (36), the third fan (24) is rotated, so that the slide block (37) moves into the second slide groove (42) and moves in a direction away from the processing groove (26), thereby disassembling the third fan (24), when the third fan (24) needs to be installed, the slide block (37) is aligned with the first slide groove (36) to push the third fan (24), so that the slide block (37) drives the limiting block (38) to finally move into the clamping groove (39).
