Coix has rich nutritional and medicinal value, and there are many records of this in ancient Chinese books. Job's tears rice is known as the best rice. After planting and harvesting, coix needs to be shelled. However, after shelling, a layer of brown-yellow substance remains on the surface of coix. Although it does not affect normal consumption, it is not beautiful enough. Therefore, it is often polished after shelling, and then the common white coix rice is obtained.

The guide rod 208 is fixedly connected to the front and rear sides of the mounting shell 203, and the guide rod 208 is slidably connected to the inside of the upper hopper 101. The feeding mechanism 3 is arranged on the right side of the polisher 1, and the feeding mechanism 3 includes a mounting frame 301, and the upper end of the mounting frame 301 is slidably connected to a material trough 304, and the lower end of the material trough 304 is fixedly connected to a lower hopper 305.

[0026] In the present embodiment, the material trough 304 can slide to the top of the upper hopper 101 to drop the coix seed brown rice to the inner side of the screening box 204, and the mounting shell 203 can reciprocate inside the upper hopper 101 through the guide rod 208, thereby driving the screening box 204 and the material trough 304 to reciprocate inside to screen and filter the coix seed brown rice, and can fully screen the coix seed so that impurities remain inside the screening box 204, thereby increasing the screening effect of the coix seed and improving the processing quality of the coix seed. The coix seed rice falls to the bottom of the screen 210 and enters the polishing machine 1 through the upper hopper 101 for polishing and yellow film removal operations, so that it can be loaded and replenished in time to ensure the normal polishing processing of the polishing machine 1 and improve the processing efficiency of the coix seed.

[0027] Example 2

[0028] Please refer to Figure 2-Figure 3 As shown, the screening mechanism 2 also includes a mounting plate 201, a driving motor 202 is fixedly mounted on one side of the mounting plate 201, an output end of the driving motor 202 extends to the other side of the mounting plate 201 and is fixedly connected to a crank 205, the end of the crank 205 is rotatably connected to a connecting rod 206, an end of the connecting rod 206 away from the crank 205 is hinged with a mounting seat 207, and the mounting seat 207 is fixedly connected to a guide rod 208.

[0029] The left and right sides of the upper end of the screening box 204 are fixedly connected to limit plates 209 .

[0030] In this solution, the driving motor 202 is electrically connected to the external power supply, and the driving motor 202 can drive the crank 205 to rotate, and then drive the front guide rod 208 to move back and forth through the connecting rod 206 and the mounting seat 207, thereby driving the mounting shell 203 to move back and forth, thereby realizing the reciprocating screening operation of the screening box 204 on the coix seeds, and the screening box 204 can be moved from the inside of the mounting shell 203 to the outside of the upper end of the mounting shell 203 through the limiting plate 209, so as to facilitate the cleaning of impurities inside the screening box 204.

[0031] Example 3

[0032] Please refer to Figure 4-Figure 5 As shown, the feeding mechanism 3 also includes two sets of driving screws 302, and the two sets of driving screws 302 are rotatably connected to the inner side of the mounting frame 301. The lower end of the material trough 304 is fixedly connected with a slider 306, and the slider 306 is threadedly connected to the driving screw 302. One end of the driving screw 302 extends to the right side of the mounting frame 301 and is fixedly connected with a pulley 303. The two sets of pulleys 303 are connected by belt transmission.
