In use, rice is placed inside the top box 2 using the feed port, and then the rice inside the top box 2 is gradually discharged using the rice discharge mechanism, so that the rice can fall from the top box 2 intermittently and evenly. At this time, the rice will pass through the connecting tube 8 and the vacuum cleaner 3 will be started. Since the interior of the connecting ring 6 and the connecting tube 8 are both configured as hollow structures, a negative pressure will be formed inside the vacuum cleaner 3 after it is started, and the inner wall of the connecting tube 8 is provided with a long groove. Therefore, the rice and waste debris in the falling process will be subject to suction. Since the waste debris is relatively light, it will be adsorbed near the long groove and enter the connecting tube 8 through the long groove, and finally enter the interior of the vacuum cleaner 3 through the connecting ring 6, so that the waste debris in the falling process can be effectively removed. After the waste debris is removed, the rice will fall directly into the bottom box 1 and can be directly collected using the discharge port.

[0027] Furthermore, the rice unloading mechanism includes a unloading barrel 15, a unloading trough 16 is provided on the surface of the unloading barrel 15, the unloading barrel 15 is rotatably connected to the opening at the bottom of the top box 2, and a driving mechanism for driving the unloading barrel 15 to rotate is provided at the bottom of the top box 2. When the rice unloading mechanism is in use, the driving mechanism drives the unloading barrel 15 to rotate. A unloading trough 16 is provided on the unloading barrel 15, so when the unloading trough 16 rotates to the top, rice will fall into the unloading trough 16. As the unloading barrel 15 rotates, the unloading trough 16 will rotate to the bottom. At this time, the rice will fall under the action of gravity and enter the bottom box 1 through the connecting barrel 8 and the connecting ring 6. The diameter of the unloading barrel 15 is adapted to the bottom opening size of the top box 2, so that the rice will not fall from the gap between the unloading barrel 15 and the opening position.

[0028] Furthermore, the driving mechanism includes a motor 10, and a transmission shaft 11 is fixedly installed on the output shaft port of the motor 10, and a driving bevel gear 14 is fixedly installed on the surface of the transmission shaft 11, and a connecting shaft 13 is fixedly passed through the surface of the discharge barrel 15, and the discharge barrel 15 is rotatably connected to the bottom opening of the top box 2 through the connecting shaft 13, and a driven bevel gear 12 is fixedly installed on the surface of the connecting shaft 13, and the driving bevel gear 14 and the driven bevel gear 12 are meshed. When the driving mechanism is in use, the motor 10 is started, and the motor 10 drives the transmission shaft 11 to rotate, and the transmission shaft 11 drives the driving bevel gear 14 to rotate, and the driving bevel gear 14 drives the driven bevel gear 12 to rotate, and the driven bevel gear 12 drives the connecting shaft 13 to rotate, and the connecting shaft 13 drives the discharge barrel 15 to rotate, so as to facilitate the use of the discharge barrel 15 to achieve uniform intermittent discharge, wherein the rotation speed of the discharge barrel 15 can be controlled by controlling the rotation speed of the motor 10, thereby improving the convenience of use of the device.

[0029] Furthermore, a driven gear 5 is fixedly mounted on the outer wall of the connecting cylinder 8, a driving gear 4 is fixedly mounted on the surface of the transmission shaft 11, the driving gear 4 and the driven gear 5 are meshed, and a cross rod 22 is evenly fixedly mounted on the inner wall of the connecting cylinder 8. In order to make the absorption effect of waste crumbs better during the falling process of rice and avoid the waste crumbs being blocked by rice during the falling process and unable to be effectively adsorbed, a cross rod 22 is provided inside the connecting cylinder 8. When the motor 10 drives the transmission shaft 11 to rotate, it can drive the driving gear 4 to rotate, the driving gear 4 drives the driven gear 5 to rotate, and the driven gear 5 drives the connecting cylinder 8 to rotate, thereby driving the internal cross rod 22 to rotate synchronously. When the cross rod 22 rotates, it will scatter the rice in the falling process, thereby facilitating the adsorption of waste crumbs.

[0030] Furthermore, a connecting rod 9 is slidably passed through the top of the top box 2, and a steel ball 20 is movably connected to the bottom end of the connecting rod 9. An anti-blocking rod 19 is fixedly installed on the surface of the connecting rod 9 at the position of the bottom opening of the top box 2, and an eccentric wheel 21 is fixedly installed on the surface of the lower barrel 15. The eccentric wheel 21 is in contact with the steel ball 20. In order to allow the rice to pass through the bottom opening of the top box 2 smoothly and avoid blockage due to excessive rice, an anti-blocking rod 19 can be set at the position of the bottom opening. When the lower barrel 15 rotates, the eccentric wheel 21 can be driven to rotate, and the anti-blocking rod 19 is installed on the connecting rod 9. The bottom of the connecting rod 9 is in contact with the edge of the eccentric wheel 21 through the steel ball 20. Therefore, as the eccentric wheel 21 rotates, the connecting rod 9 can be driven to slide up and down, thereby driving the anti-blocking rod 19 to move up and down, thereby playing an anti-blocking function.

[0031] Furthermore, a round block 18 is fixedly installed on the top of the connecting rod 9, and a spring 17 is sleeved on the surface of the connecting rod 9. The two ends of the spring 17 are fixedly connected to the top of the top box 2 and the round block 18 respectively. In order to make the connecting rod 9 move up and down more smoothly, a round block 18 is set on the top of the connecting rod 9, and a spring 17 is sleeved on the connecting rod 9. The upward movement of the connecting rod 9 can be directly pushed upward by the eccentric wheel 21, and the downward movement of the connecting rod 9 can be powered by the tension of the spring 17, which is convenient to use.

[0032] In summary, during use, the rice is placed inside the top box 2 using the feed port, and then the rice inside the top box 2 is gradually discharged using the rice discharge mechanism, so that the rice can fall from the top box 2 intermittently and evenly. At this time, the rice will pass through the connecting tube 8 and the vacuum cleaner 3 will be started. Since the interior of the connecting ring 6 and the connecting tube 8 are both configured as hollow structures, a negative pressure will be formed inside the vacuum cleaner 3 after it is started, and the inner wall of the connecting tube 8 is provided with a long groove. Therefore, the rice and waste debris in the falling process will be subject to suction. Since the waste debris is relatively light, it will be adsorbed near the long groove and enter the connecting tube 8 through the long groove, and finally enter the interior of the vacuum cleaner 3 through the connecting ring 6, so that the waste debris in the falling process can be effectively removed. After the waste debris is removed, the rice will fall directly into the bottom box 1 and be used. The discharge port can be collected directly. When the rice feeding mechanism is in use, the driving mechanism drives the feeding barrel 15 to rotate. A feeding chute 16 is provided on the feeding barrel 15. Therefore, when the feeding chute 16 rotates to the top, rice will fall into the feeding chute 16. As the feeding barrel 15 rotates, the feeding chute 16 will rotate to the bottom. At this time, under the action of gravity, the rice will fall and pass through the connecting barrel 8 and the connecting ring 6 into the bottom box 1. The diameter of the feeding barrel 15 is adapted to the bottom opening size of the top box 2, so that the rice will not fall from the gap between the feeding barrel 15 and the opening position. When the driving mechanism is in use, the motor 10 is started, the motor 10 drives the transmission shaft 11 to rotate, the transmission shaft 11 drives the active bevel gear 14 to rotate, and the active bevel gear 14 drives The driven bevel gear 12 rotates, the driven bevel gear 12 drives the connecting shaft 13 to rotate, and the connecting shaft 13 drives the discharge barrel 15 to rotate, so that it is convenient to use the discharge barrel 15 to achieve uniform intermittent discharge, wherein the rotation speed of the discharge barrel 15 can be controlled by controlling the rotation speed of the motor 10, thereby improving the convenience of using the device. In order to make the waste scraps absorb better during the falling process of rice and avoid the waste scraps being blocked by rice during the falling process and unable to be effectively adsorbed, a cross rod 22 is set inside the connecting barrel 8. When the motor 10 drives the transmission shaft 11 to rotate, it can drive the driving gear 4 to rotate, the driving gear 4 drives the driven gear 5 to rotate, and the driven gear 5 drives the connecting barrel 8 to rotate, thereby driving the internal cross rod 22 to rotate simultaneously When the rice is lowered, the cross rod 22 will scatter the rice in the falling process when it rotates, which is helpful for the absorption of waste chips. In order to allow the rice to pass through the bottom opening of the top box 2 smoothly and avoid the blockage of a lot of rice, an anti-blocking rod 19 can be set at the position of the bottom opening. When the lower barrel 15 rotates, the eccentric wheel 21 can be driven to rotate, and the anti-blocking rod 19 is installed on the connecting rod 9. The bottom of the connecting rod 9 is in contact with the edge of the eccentric wheel 21 through the steel ball 20. Therefore, as the eccentric wheel 21 rotates, the connecting rod 9 can be driven to slide up and down, thereby driving the anti-blocking rod 19 to move up and down, thereby playing an anti-blocking function. In order to make the up and down movement of the connecting rod 9 smoother, a round block 18 is set on the top of the connecting rod 9, and a spring 17 is sleeved on the connecting rod 9.The upward movement of the connecting rod 9 can be directly pushed up by the eccentric wheel 21, and the downward movement of the connecting rod 9 can be powered by the tension of the spring 17, which is convenient for use.
