Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] See also Figures 1-6 The utility model provides a technical solution: a rice vibration impurity removal device, comprising a box body 1, a feeding port 2 is provided on the top of the box body 1, a material taking port 3 is provided on the front of the box body 1, a vibration screening frame 4 is provided inside the box body 1, and vibration equipment 5 is provided on the left and right sides of the vibration screening frame 4. A lifting mechanism 6 is provided on the box body 1, and unremoved rice is put into the feeding port 2, and then vibrated and screened by the vibration screening frame 4. The vibration equipment 5 is provided to vibrate the vibration screening frame 4 and take out the vibrated rice from the material taking port 3;

[0023] The lifting mechanism 6 includes a second motor 601 and a circulating air pump 607. The second motor 601 is fixedly mounted on the left outer wall of the box body 1. The output end of the second motor 601 is fixedly mounted with a rotating shaft 602. The rotating shaft 602 passes through the outer wall of the box body 1 through a bearing. The outer wall of the rotating shaft 602 is fixedly sleeved with a lifting plate 603. The rotating shaft 602 and the lifting plate 603 are hollow inside, and the rotating shaft 602 and the lifting plate 603 are internally connected. The outer wall of the lifting plate 603 is provided with a blowing hole 604. The circulating air pump The outlet end of 607 is connected to a diverter pipe 606 through a pipeline, and the interior of the diverter pipe 606 is connected to a rotary joint 605 through a pipeline. The right end of the rotary joint 605 is connected to the left end of the rotating shaft 602. The air inlet end of the circulating air pump 607 is connected to a recovery box 608 through a pipeline. The top of the recovery box 608 is connected to a hose 609. The top of the hose 609 is connected to a suction head 6011. The suction head 6011 extends into the box body 1. The suction head 6011 A blocking plate 6010 is fixedly installed on the top of the screen. The blocking plate 6010 is stuck in the feed port 2. A high-speed airflow is generated by the circulating air pump 607. The airflow enters the diversion pipe 606 from the pipeline, and then enters the rotary joint 605, the rotating shaft 602, and the lifting plate 603 in sequence. It is blown out from the blowing hole 1 604 on the lifting plate 603, blowing up the impurities raised to a certain extent by the vibration of the screen. The rotating shaft 602 is driven to rotate by the motor 2 601, and then the lifting plate 603 is driven to rotate. The rotating lifting plate 603 lifts the impurities upward, bringing the impurities closer to the suction head 6011, and the circulating air pump 607 works to extract the air in the recovery box 608. Under the action of negative pressure, the suction head 6011 can suck in the impurities and air, thereby recovering the impurities. Because the air blowing hole 604 and the lifting plate 603 are added to blow air and lift the impurities upward, it is ensured that the impurities can be completely separated from the rice, so that the suction head 6011 will not suck in the rice when sucking in the impurities;

[0024] A limit baffle 7 is fixedly installed on the top of the blocking plate 6010. A positioning rod 8 is slidably provided on the inner wall of the end of the limit baffle 7. The bottom end of the positioning rod 8 is fixedly connected to the top of the box body 1. The limit baffle 7 is limited by the positioning rod 8. The limit baffle 7 is provided to prevent the blocking plate 6010 from falling, and the limit baffle 7 makes it easier to pull the blocking plate 6010 up and down.

[0025] A feeding port 401 is provided at the center of the vibration screen frame 4, and a leak-proof plate 402 is clamped inside the feeding port 401.

A motor 403 is fixedly installed at the bottom of the vibration screen frame 4, and the output end of the motor 403 is fixedly connected to the crank 404. The feeding port 401 is provided so that after the impurities are completely separated, the rice can be lowered from the vibration screen frame 4 into the box body 1. The leak-proof plate 402 is provided to block the feeding port 401 to prevent the rice and impurities from falling from the feeding port 401 during the impurity removal process. The crank 404 is driven to rotate by the motor 403, and then the leak-proof plate 402 is driven to rotate, thereby realizing the opening and closing of the leak-proof plate 402;

[0026] A blowing plate 9 is placed on the bottom inner wall of the box body 1, and a second blowing hole 11 is opened on the top of the blowing plate 9. A connecting pipe 10 is provided on the top of the blowing plate 9. The right end of the connecting pipe 10 is connected to the inside of the shunt pipe 606. During the impurity removal process, a high-speed airflow enters the connecting pipe 10 from the circulating air pump 607, then enters the blowing plate 9, and finally blows out from the second blowing hole 11, that is, the air is discharged from the bottom to the top, so as to blow up the impurities mixed in the rice, thereby further increasing the lifting amplitude of the impurities.

[0027] The blowing holes 1 604 on the lifting plate 603 are close to the edge of the lifting plate 603. The blowing holes 1 604 are densely distributed on the edge of the lifting plate 603. Compared with being evenly opened on the lifting plate 603, the blowing holes 1 604 make the airflow more directed and the blown airflow stronger. There are multiple hoses 609, and they are evenly spaced on the suction head 6011. For a longer suction head 6011, the provision of multiple hoses 609 can ensure the uniformity of the suction force of the suction head 6011.

[0028] A separating rubber pad 12 is fixedly installed on the top of the vibrating screen frame 4, and a connecting plate 13 is fixedly installed on the inner wall of the box body 1. The top of the separating rubber pad 12 is fixedly connected to the bottom of the connecting plate 13. The separating rubber pad 12 surrounds the top of the vibrating screen frame 4. The connecting plate 13 is provided for installing the separating rubber pad 12. The separating rubber pad 12 is provided to completely isolate the space above the vibrating screen frame 4 from the space below the vibrating screen frame 4 to prevent rice and impurities from falling from the gap between the vibrating screen frame 4 and the inner wall of the box body 1 to the bottom of the vibrating screen frame 4 during the vibration process.

[0029] Working principle: When in use, pour the unremoved rice into the vibration screen frame 4 from the feed port 2, then insert the sealing plate 6010 into the feed port 2, turn on the vibration device 5 to vibrate the vibration screen frame 4, so that the impurities mixed in the rice are lifted to a certain extent, turn on the motor 2 601 and the circulating air pump 607, the circulating air pump 607 generates a high-speed airflow, the airflow enters the diversion pipe 606 from the pipeline, and then enters the rotary joint 605, the rotating shaft 602, and the lifting plate 603 in turn, and is blown out from the blowing hole 1 604 on the lifting plate 603, blowing up the impurities lifted to a certain extent by the vibration screen, and driving the rotating shaft 602 to rotate through the motor 2 601, thereby driving the lifting plate 603 to rotate, so that the rotating lifting plate 603 lifts the impurities upward, bringing the impurities closer to the screen. The suction head 6011 and the circulating air pump 607 work to extract the air in the recovery box 608. Under the action of negative pressure, the suction head 6011 can suck in impurities and air to realize the recovery of impurities. Because the blowing hole 1 604 and the lifting plate 603 for blowing and lifting impurities upward are added, it is ensured that impurities can be completely separated from rice, so that the suction head 6011 will not suck in rice when sucking in impurities. After the impurities are removed, turn off the motor 2 601 and the circulating air pump 607, turn on the motor 1 403 to drive the crank 404 to rotate, and then drive the leakage prevention plate 402 to rotate, so that the discharge port 401 leaks out. At this time, the vibration of the screen frame 4 can make the rice roll. When the rice rolls to the discharge port 401, it will fall from the discharge port 401. Open the feeding port 3 to take out the rice.

[0030] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
