[0054] Third step: when the first disc 113 and the second disc 1131 rotate 90 degrees again, the second round pin 118 will enter the fifth sliding groove 115, the second round pin 118 drives the third round rod 119 to move away from the first disc 113 side through the second round ring 117, the third round rod 119 drives the fifth gear 218 to disengage from the first tooth ring 203 and the second tooth ring 204 respectively and no longer meshed;

[0055] Meanwhile, the first round pin 102 enters into the second sliding slot 104, the first round pin 102 drives the first round rod 101 to move towards the side of the second disc 1131 through the first round ring 103, the first round rod 101 drives the first gear 209 to engage with the first inner tooth ring 210, the first inner tooth ring 210 drives the second gear 211 to rotate, the second gear 211 drives the first filter cylinder 202 to rotate reversely through the first tooth ring 203, at this time, the spiral blade 201 in the first filter cylinder 202 will make the screened brown rice to be discharged, the first leather strip 208 and the second leather strip 217 knock the outer wall of the first filter cylinder 202 to prevent residual, so that the intermittent falling of a certain amount of brown rice is divided into three parts, and the processing of the extrusion roller 307 is more thorough.

[0056] With the first disc 113 and the second disc 1131 rotating again by 90 degrees, the second round pin 118 is still in the fifth sliding slot 115, at this time, the first round pin 102 enters into the fourth sliding slot 107, the first round pin 102 drives the first round rod 101 to move away from the side of the second disc 1131 through the first round ring 103, the first round rod 101 drives the first gear 209 to disengage from the first inner tooth ring 210, and at the same time, the fourth gear 214 is engaged with the second inner tooth ring 213, the second inner tooth ring 213 drives the third gear 212 to rotate, the third gear 212 drives the second filter cylinder 205 to rotate reversely through the second tooth ring 204, so that the screened brown rice enters into the first filter cylinder 202, the first leather strip 208 and the second leather strip 217 knock the outer wall of the second filter cylinder 205 to prevent residual;

[0057] Then with the first disc 113 and the second disc 1131 rotating again by 90 degrees, the second round pin 118 reenters into the sixth sliding slot 116, the first round pin 102 enters into the third sliding slot 106, and the steps of the first step are repeated;

[0058] The fourth step: the fifth round rod 301 and the sixth round rod 308 rotate to drive the extrusion roller 307 to rotate, so that the screened broken rice, small particle rice and large particle rice are processed respectively, so that the brown rice of different sizes is processed, and the screened rice does not fall at one time, so that the processing is more thorough, and then falls on the filter screen 304, at this time, the sixth round rod 308 drives the two cams 302 at both ends to rotate, the cam 302 drives the filter screen 304 to move up and down through the connecting rod 303, so that the rolled brown rice is screened, the screened rice is classified through the setting of the partition plate 305, and collection is facilitated.

[0059] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
