[0002] Rice is a finished product made from paddy through processes such as cleaning, hulling, milling, and finishing. During the storage of rice, pests are the most serious problem faced by rice merchants. Pests cause the rice to lose weight, reduce its quality, and lead to food safety issues.

[0003] In rice processing, it is necessary to remove iron filings and iron objects from the rice to avoid damage to the processing machinery. However, when rice is piled up or transported, it can become quite thick. During demagnetization, magnetic rods are used to remove the iron objects. Iron objects located inside the rice are blocked by the rice, preventing them from being effectively attracted. This results in incomplete demagnetization of the rice, making it inconvenient to use. Utility Model Content

[0028] Reference Figure 1-7 A magnetic separator for rice processing includes a connecting box 1, with a feed cylinder 2 connected to the top of the connecting box 1. Support legs 3 are fixedly installed at the bottom of the connecting box 1. A discharge plate 4 is fixedly installed at the bottom of the connecting box 1 away from the feed cylinder 2. A groove is formed in the top of the connecting box 1. Barrier plates 17 are fixedly installed on both ends of the top wall of the connecting box 1 relative to the groove. An electromagnetic plate 6 is fixedly installed between the two barrier plates 17. A connecting frame 12 is provided at the bottom of the electromagnetic plate 6. A lever 13 is uniformly fixedly installed at the bottom of the connecting frame 12. A drive mechanism for driving the connecting frame 12 to reciprocate is provided on the surface of the connecting box 1. A conveyor belt 5 is provided at the bottom of the connecting box 1. The end of the connecting box 1 away from the feed cylinder 2 is open. A cleaning mechanism for the electromagnetic plate 6 is provided at the bottom of the electromagnetic plate 6. The cleaning mechanism works by first pouring rice into the connecting box 1 using the feed cylinder 2. The conveyor belt 5 inside the connecting box 1 then transports the rice, causing it to move slowly. The drive mechanism drives the connecting frame 12 to move back and forth, which in turn drives the lever 13 to move synchronously. The lever 13 then moves the rice on the conveyor belt 5. At the same time, the electromagnetic plate 6 is energized to generate attraction, which attracts iron objects mixed in with the rice. The lever 13's movement of the rice makes it easier for the iron objects inside the rice to be exposed and attracted by the electromagnetic plate 6, making it convenient to use. When there are many iron objects attracted to the electromagnetic plate 6, the cleaning mechanism can be used to clean the bottom of the electromagnetic plate 6 directly, improving operational convenience.

[0029] Furthermore, a baffle 14 is slidably connected to the inside of the connecting box 1 relative to the position of the baffle 17. A screw 15 is rotatably inserted into the top of the connecting box 1. The screw 15 and the baffle 14 are threadedly connected. By setting the baffle 17 and rotating the screw 15, the baffle 17 can be moved vertically. Therefore, the thickness of the rice on the conveyor belt 5 can be controlled by adjusting the distance between the baffle 17 and the conveyor belt 5.

[0030] Furthermore, the drive mechanism includes an electric telescopic rod 10, and connecting rods 11 are fixedly installed on both sides of the connecting frame 12. Both connecting rods 11 slide through both sides of the connecting box 1. The electric telescopic rod 10 is fixedly installed on the side wall of the connecting box 1. The output end port of the electric telescopic rod 10 is fixedly connected to the connecting rod 11. In use, the drive mechanism directly starts the electric telescopic rod 10, which drives the connecting rod 11 and the connecting frame 12 to reciprocate. The direction of movement of the connecting frame 12 is perpendicular to the direction of movement of the conveyor belt 5, which further improves the stirring effect on the rice and helps the electromagnetic plate 6 to adsorb the iron products mixed in the rice.

[0031] Furthermore, the cleaning mechanism includes a cleaning rod 7, which is slidably connected inside the connecting box 1, with one end of the cleaning rod 7 sliding through the connecting box 1. The cleaning rod 7 is a hollow structure with openings on both sides. The side wall of the connecting box 1 is provided with an auxiliary mechanism to drive the cleaning rod 7 to move. In use, the cleaning mechanism uses the auxiliary mechanism to drive the cleaning rod 7 to move horizontally. The cleaning rod 7 contacts the bottom of the electromagnetic plate 6, so the opening of the cleaning rod 7 can be used to scrape off the iron products adsorbed on the bottom of the electromagnetic plate 6. The scraped iron products can fall into the interior of the cleaning rod 7.

[0032] Furthermore, the auxiliary mechanism includes a motor 9, a lead screw 8, and two fixed blocks. The two fixed blocks are fixedly installed on the side wall of the connecting box 1. The lead screw 8 and the two fixed blocks are rotatably connected. The motor 9 is fixedly installed on the side wall of the connecting box 1. The output shaft port of the motor 9 is fixedly connected to the lead screw 8. The lead screw 8 is threaded through the cleaning rod 7. In use, the auxiliary mechanism starts the motor 9, which drives the lead screw 8 to rotate. The lead screw 8 drives the cleaning rod 7 to move horizontally. The surface of the lead screw 8 is a reciprocating thread, which facilitates the reciprocating movement of the cleaning rod 7 and achieves thorough cleaning of the bottom of the electromagnetic plate 6.

[0033] Furthermore, two discharge holes 16 are provided on the side wall of the connecting box 1, and the bottom wall of the cleaning rod 7 is set as an inclined surface. By setting the discharge holes 16 and the inclined surface, the iron products falling inside the cleaning rod 7 will slide to the lower position through the inclined surface. When the end of the cleaning rod 7 is aligned with the discharge hole 16, the iron products can slide out through the discharge hole 16 for convenient use.

[0034] In summary, during use, rice is first poured into the connecting box 1 using the feeding cylinder 2. The conveyor belt 5 inside the connecting box 1 then transports the rice, causing it to move slowly. The drive mechanism drives the connecting frame 12 to reciprocate, which in turn drives the lever 13 to move synchronously. The lever 13 then moves the rice on the conveyor belt 5. Simultaneously, the electromagnetic plate 6 is energized to generate attraction, which attracts any iron objects mixed in with the rice. The lever 13's movement of the rice further removes the iron objects inside. The iron products are more easily exposed and thus attracted by the electromagnetic plate 6, making them convenient to use. When a large number of iron products are attracted to the electromagnetic plate 6, the cleaning mechanism can be used to clean the bottom of the electromagnetic plate 6 directly, improving operational convenience. By setting a barrier plate 17 and rotating the screw 15, the barrier plate 17 can be moved vertically. Therefore, the thickness of the rice on the conveyor belt 5 can be controlled by adjusting the distance between the barrier plate 17 and the conveyor belt 5. During use, the drive mechanism directly starts the electric telescopic rod 10, which drives the connecting rod 11 and the connecting frame 12 to move back and forth. The moving direction of the connecting frame 12 is perpendicular to the moving direction of the conveyor belt 5, further improving the stirring effect on the rice and helping the electromagnetic plate 6 to attract the iron products mixed in the rice. During use, the cleaning mechanism uses an auxiliary mechanism to drive the cleaning rod 7 to move horizontally. The cleaning rod 7 contacts the bottom of the electromagnetic plate 6, so the opening of the cleaning rod 7 can be used to scrape off the iron products attracted to the bottom of the electromagnetic plate 6. The scraped iron products can fall onto the cleaning rod. Inside the auxiliary mechanism 7, when in use, the motor 9 is started, and the motor 9 drives the lead screw 8 to rotate. The lead screw 8 drives the cleaning rod 7 to move horizontally. The surface of the lead screw 8 is a reciprocating thread, which facilitates the reciprocating movement of the cleaning rod 7 and achieves thorough cleaning of the bottom of the electromagnetic plate 6. By setting the discharge hole 16 and the inclined surface, the iron products falling inside the cleaning rod 7 will slide to the lower position through the inclined surface. When the end of the cleaning rod 7 is aligned with the discharge hole 16, the iron products can slide out through the discharge hole 16 for easy use.
