[0001] This utility model relates to the field of grain processing, and in particular to an automatic separation and conveying device for rice husks and broken rice. Background Technology
[0002] In rice processing, after hulling and milling, the finished rice often contains rice husks and broken rice. This mixture not only affects the appearance and quality of the finished rice but also reduces its commercial value and can even impact the efficiency of subsequent processing. Therefore, efficient separation of rice husks and broken rice is a crucial step in rice processing, directly affecting the product's market competitiveness. Traditional separation methods mainly rely on manual screening or single mechanical separation devices, which suffer from low efficiency, poor precision, and high labor intensity. With the development of large-scale and automated grain processing, the market demand for automated, high-precision, and continuous separation and conveying devices is becoming increasingly urgent.
[0003] Traditional rice husk and broken rice separation devices have limited range of vibration frequency and amplitude adjustment. The screen and frame are mostly fixedly connected, making it impossible to replace the screen with a suitable one according to the size of the rice grains. Moreover, the insufficient vibration amplitude means that rice husks and broken rice cannot be completely separated during operation, resulting in incomplete separation.
[0004] To address this problem, an automatic rice husk and broken rice separation and conveying device is proposed. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an automatic rice husk and broken rice separation and conveying device, which aims to improve the problems of insufficient vibration leading to unclean screening and the inability of the screen to be replaced according to the size of rice husk and broken rice, resulting in low work efficiency in the prior art.

[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, when the rice husk and broken rice separation device is ready to work, the motor is started, and the output end of the motor drives the disc. The disc drives the connecting shaft one, the rotating rod one, and the connecting shaft two to rotate. One end of the rotating rod two rotates outside the connecting shaft two, and the other end rotates inside the fixed plate. The connecting block is used to fix the fixed plate on the collection box. The fixed plate drives the collection box to vibrate back and forth continuously through the rotation of the rotating rod two and the turntable, which solves the problem of insufficient vibration frequency of traditional rice husk and broken rice separation devices, resulting in unclean screening.
[0025] 2. In this utility model, when the rice husks and broken rice are of different sizes and the sieve needs to be replaced, the pin is pulled out of the fixing block by pulling the pull ring.

Then, remove the screen 5 from the mounting frame 3 using the handle 6. After replacing the screen 5 with the appropriate one, insert the fixing block 7 into the mounting frame 3. Then, release the pin 11, which will re-insert into the fixing block 7 under the action of the spring 23, completing the replacement of the screen 5. Then, pour the rice husks and broken rice into the screen 5, start the motor 10, and the output of the motor 10 drives the rotation of the turntable 15. The turntable 15 drives the rotating rod through the connecting shaft 16. The rotation of 17 causes the connecting shaft 12 on the rotating rod 13 to rotate, so the rotating rod 13 will rotate inside the fixed plate 18. Finally, the roller 20 at the bottom of the collection box 2 slides back and forth in the groove 21 inside the support frame 1. Then, the collection box 2 drives the connecting column 4 at the top to vibrate the mounting frame 3 and the screen 5 inside it. Then, the broken rice falls into the collection box 2 at the bottom under the vibration of the screen 5. The broken rice is then discharged through the discharge port 19. After screening is completed, the baffle 9 is lifted on the outside of the mounting frame 3 by the handle, and the rice husks are discharged through the discharge port 8.
