[0075] Working principle: the staff first starts the motor 21, the vibration motor 9 and the blower 12. The output end of the motor 21 rotates to drive a second sprocket 18 and a third rice-husking roller 4 to rotate at the same time. Under the action of a pair of third gears 16, another third rice-husking roller 4 and another second sprocket 18 can be rotated at the same time. At this time, the rotation of the pair of second sprockets 18 respectively drives a pair of chains 19 to rotate, so that a pair of first sprockets 17 rotates at the same time. The rotation of the pair of first sprockets 17 can respectively drive a first rice-husking roller 2 and a second rice-husking roller 3 to rotate. At this time, under the action of a pair of first gears 14 and a pair of second gears 15, another first rice-husking roller 2 and another rice-husking roller 3 rotate at the same time. At this time, the staff adds rice into the feeding hopper, and the rice falls from the feed port into the machine chamber 1. At this time, the guide block 13 can feed the rice that falls from the feed port. The rice is guided so that it can fall between a pair of first husking rollers 2 and a pair of second husking rollers 3 respectively. At this time, the pair of first husking rollers 2 and the pair of second husking rollers 3 can process the rice for the first time. The processed rice falls from the second baffle 6 to between a pair of third husking rollers 4. The pair of third husking rollers 4 can process the rice for the second time, and the rice that was not completely processed for the first time can be processed completely, thereby improving the processing quality. At this time, the processed rice falls onto the filter screen 8, and the vibration motor 9 can vibrate the square frame 7 so that the filter screen 8 can screen the processed rice. The screened rice falls into the material box, which is convenient for the staff to collect. The rice husks remain on the filter screen 8. At this time, the hair dryer 12 blows the rice husks on the filter screen 8 from the waste material port 11 into the collection box 10, which is convenient for the staff to collect the rice husks and brings convenience to people.
