[0017] (III) Beneficial Effects

[0018] 1. A dual-head motor drives the first gear to rotate clockwise, which in turn drives the second gear to rotate counterclockwise. The second gear then drives the gear ring to rotate counterclockwise, which in turn drives the dispensing disc to rotate counterclockwise. When the discharge port rotates to the bottom of the discharge pipe, rice flows out from inside the discharge pipe. Because the first gear is smaller than the second gear, the gear ring rotates more slowly, ensuring that the amount of rice flowing out each time is roughly the same, thus achieving the function of quantitative dispensing.

[0019] 2. Start the dual-head motor, then put the rice into the outer shell. The rice falls onto the top of the screening plate. The dual-head motor drives the first protrusion plate to rotate clockwise. The first and second protrusion plates continuously offset each other, generating vibration. The spring and piston rod continuously compress and extend, increasing the vibration frequency. The second protrusion plate drives the outer shell to vibrate, and the outer shell drives the screening plate to vibrate for screening. The rice remaining on the surface of the screening plate will flow out of the outer shell through the discharge pipe. At the same time, the dual-head motor drives the connecting rod to rotate clockwise, and the connecting rod drives the scraper to rotate clockwise. There is a gap between the scraper and the screening plate, so the screening plate will not interfere with the normal operation of the scraper. The scraper pushes the rice on the surface of the screening plate, speeding up the screening and increasing the efficiency of the rice flowing out of the outer shell, thereby achieving the function of accelerating the screening efficiency.

[0026] This application provides an automatic rice sorting and packaging machine, effectively solving the problem described above where, after rice is sorted, it is difficult to achieve quantitative packaging. The collected rice requires workers to place it into other devices for quantitative packaging, increasing workflow and time, and reducing overall production efficiency. A dual-head motor drives the first gear to rotate clockwise, which in turn drives the second gear to rotate counter-clockwise. The second gear drives the gear ring to rotate counter-clockwise, which in turn drives the packaging disc to rotate counter-clockwise. When the discharge port rotates to the bottom of the discharge pipe, rice flows out from inside the pipe. Because the first gear is smaller than the second gear, the gear ring rotates more slowly, ensuring that the amount of rice flowing out each time is roughly the same, thus achieving quantitative packaging. The dual-head motor is activated... The machine then places rice inside the outer shell, where it falls onto the top of the sieving plate. A dual-head motor drives the first protruding plate to rotate clockwise. The first and second protruding plates continuously offset each other, generating vibration. The spring and piston rod continuously compress and extend, increasing the vibration frequency. The second protruding plate drives the outer shell to vibrate, which in turn drives the sieving plate to vibrate for sieving. The rice remaining on the surface of the sieving plate flows out of the outer shell through the discharge pipe. Simultaneously, the dual-head motor drives the connecting rod to rotate clockwise, which in turn drives the scraper to rotate clockwise. There is a gap between the scraper and the sieving plate, so the sieving plate will not interfere with the normal operation of the scraper. The scraper pushes the rice on the surface of the sieving plate, accelerating the sieving process and increasing the efficiency of the rice flowing out of the outer shell, thus achieving the function of accelerating the sieving efficiency.

[0027] Example

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the technical problem that after the rice is screened as described above, it is difficult to achieve quantitative packaging. The collected rice needs to be put into other devices for quantitative packaging by workers, which increases the workflow and time and reduces the overall production efficiency. The general idea is as follows: An automatic rice packaging and screening machine includes a base plate 11. A packaging mechanism is provided on the top of the base plate 11. The packaging mechanism includes a dual-head motor 12, a first gear 13, a second gear 14, a gear ring 15, a packaging disc 16, and a discharge port 17. The dual-head motor 12 is fixedly installed on the top of the base plate 11. The first gear 13 is fixedly installed on the side wall of the bottom output shaft of the dual-head motor 12. The first gear 13 meshes with the second gear 14. The gear ring 16... 5 meshes with the second gear 14, which is rotatably mounted on the bottom of the base plate 11. The dispensing tray 16 is fixedly mounted on the top of the gear ring 15 and rotatably mounted on the side wall of the base plate 11. The discharge port 17 is opened inside the dispensing tray 16. The dual-head motor 12 drives the first gear 13 to rotate clockwise, the first gear 13 drives the second gear 14 to rotate counterclockwise, the second gear 14 drives the gear ring 15 to rotate counterclockwise, and the gear ring 15 drives the dispensing tray 16 to rotate counterclockwise. When the discharge port 17 rotates to the bottom of the discharge pipe 25, rice flows out from inside the discharge pipe 25. Because the first gear 13 is smaller than the second gear 14, the gear ring 15 rotates more slowly, so that the amount of rice flowing out each time is not much different, thereby achieving the function of quantitative dispensing.

[0029] A first protrusion plate 18 is fixedly installed on the side wall of the top output shaft of the dual-head motor 12. A connecting rod 28 is fixedly installed inside the top output shaft of the dual-head motor 12. A second protrusion plate 19 is rotatably installed on the side wall of the connecting rod 28. A spring 21 is fixedly installed at the bottom of the second protrusion plate 19. A piston rod 27 is inserted into the spring 21. The bottom of the spring 21 is fixedly installed to the base plate 11. A housing 22 is fixedly installed on the top of the second protrusion plate 19. A scraper 23 is fixedly installed on the side wall of the connecting rod 28. A sieve plate 24 is fixedly installed inside the housing 22. A discharge pipe 25 is fixedly installed on the side wall of the housing 22. When the dual-head motor 12 is started, rice is put into the housing 22. The rice falls on the top of the sieve plate 24. The dual-head motor 12 drives the first protrusion plate 18 to rotate clockwise. The first protrusion plate 18 and the second protrusion plate 19 continuously vibrate by being staggered. The spring 21 and the piston rod 27 continuously compress and extend to increase the vibration frequency. The second protrusion plate 19 drives the outer shell 22 to vibrate, and the outer shell 22 drives the screening plate 24 to vibrate for screening. The rice that remains on the surface of the screening plate 24 will flow out of the inner shell 22 through the discharge pipe 25. At the same time, the double-head motor 12 drives the connecting rod 28 to rotate clockwise. The connecting rod 28 drives the scraper 23 to rotate clockwise. There is a gap between the scraper 23 and the screening plate 24, so the screening plate 24 will not interfere with the normal operation of the scraper 23. The scraper 23 drives the rice on the surface of the screening plate 24, which speeds up the screening and the efficiency of the rice flowing out of the inner shell 22, thereby achieving the function of speeding up the screening efficiency.

[0030] The bottom of the base plate 11 is fixedly installed with support legs 26. The bottom area of ​​the support legs 26 is large, which ensures that the device can operate stably.

[0031] To address the problems existing in the prior art, this utility model provides an automatic rice sorting and dispensing machine. A dual-head motor 12 drives a first gear 13 to rotate clockwise, which in turn drives a second gear 14 to rotate counter-clockwise. The second gear 14 drives a gear ring 15 to rotate counter-clockwise, which in turn drives a dispensing disc 16 to rotate counter-clockwise. When the discharge port 17 rotates to the bottom of the discharge pipe 25, rice flows out from inside the discharge pipe 25. Because the first gear 13 is smaller than the second gear 14, the gear ring 15 rotates more slowly, ensuring that the amount of rice flowing out each time is roughly the same, thus achieving the function of quantitative dispensing. The dual-head motor 12 is started, and rice is placed inside the outer casing 22. The rice falls onto the top of the sieving plate 24, and the dual-head motor 12 drives the first protrusion plate 18 clockwise. As the needle rotates, the first protrusion plate 18 and the second protrusion plate 19 continuously offset each other, generating vibration. The spring 21 and the piston rod 27 continuously compress and extend, increasing the vibration frequency. The second protrusion plate 19 drives the outer shell 22 to vibrate, and the outer shell 22 drives the screening plate 24 to vibrate for screening. The rice remaining on the surface of the screening plate 24 will flow out of the inner shell 22 through the discharge pipe 25. At the same time, the dual-head motor 12 drives the connecting rod 28 to rotate clockwise, and the connecting rod 28 drives the scraper 23 to rotate clockwise. There is a gap between the scraper 23 and the screening plate 24, so the screening plate 24 will not interfere with the normal operation of the scraper 23. The scraper 23 drives the rice on the surface of the screening plate 24, speeding up the screening and increasing the efficiency of the rice flowing out of the inner shell 22, thereby achieving the function of speeding up the screening efficiency.

[0032] Working principle:

[0033] The first step is to start the dual-head motor 12, then put the rice into the outer shell 22. The rice falls on top of the sieve plate 24. The dual-head motor 12 drives the first protrusion plate 18 to rotate clockwise. The first protrusion plate 18 and the second protrusion plate 19 continuously offset each other to generate vibration. The spring 21 and the piston rod 27 continuously compress and extend to increase the vibration frequency. The second protrusion plate 19 drives the outer shell 22 to vibrate. The outer shell 22 drives the sieve plate 24 to vibrate for sieving. The rice that stays on the surface of the sieve plate 24 will flow out of the outer shell 22 through the discharge pipe 25. At the same time, the dual-head motor 12 drives the connecting rod 28 to rotate clockwise. The connecting rod 28 drives the scraper 23 to rotate clockwise. There is a gap between the scraper 23 and the sieve plate 24, so the sieve plate 24 will not interfere with the normal operation of the scraper 23. The scraper 23 drives the rice on the surface of the sieve plate 24, which speeds up the sieving and the efficiency of the rice flowing out of the outer shell 22, thereby achieving the function of speeding up the sieving efficiency.

[0034] In the second step, the dual-head motor 12 drives the first gear 13 to rotate clockwise, the first gear 13 drives the second gear 14 to rotate counterclockwise, the second gear 14 drives the gear ring 15 to rotate counterclockwise, and the gear ring 15 drives the dispensing tray 16 to rotate counterclockwise. When the discharge port 17 rotates to the bottom of the discharge pipe 25, the rice flows out from inside the discharge pipe 25. Because the first gear 13 is smaller than the second gear 14, the gear ring 15 rotates more slowly, so that the amount of rice flowing out each time is not much different, thus achieving the function of quantitative dispensing.

[0035] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
