Since the elliptical disk 718 is elliptical, it can drive the push-pull rod 719 to move up and down, and the push-pull rod 719 drives the screening frame 701 to move up and down. Therefore, when the rice grains enter the screening frame 701, the rice grains can be screened.

[0023] The dust blowing mechanism 8 includes an air duct 801, which can guide the airflow. The bottom of the air duct 801 is fixedly connected to the outside of the top shell 2, and the top of the air duct 801 is fixedly connected to a fan 802.

The bottom of the outer cylinder 805 is fixedly connected to the top of the screening frame 701. The bottom of the outer cylinder 805 is provided with a short slot and a long slot. The bottom of the dust auger 803 can extend into the upper half of the long slot and will not extend into the short slot. The outside of the top shell 2 is located on one side of the air duct 801 and is fixedly connected with a dust shield 808. The dust shield 808 can prevent dust from being discharged through the air duct 801. The conical cover 806 is arranged inside the top shell 2. The outer periphery of the guide hopper 807 is slidably connected to Inside the top shell 2, the output shaft of the motor 4 is connected to the fan 802 through a belt. When the rice enters the top shell 2, the motor 4 is started, and the output shaft of the motor 4 drives the fan 802 to rotate through the belt, so that the fan 802 can generate wind, and the airflow will enter the top shell 2 through the introduction of the air guide 801. At this time, the rice will first pass through the conical cover 806 to be broken up, and the broken rice grains will be easier to use the airflow to blow up impurities in the rice grains. When too much rice grains enter at one time and fall into the screening frame 701, the rotation of the rotating shaft 6 drives the dust auger 8 03 rotates, at this time, the rice grains can contact the dust auger 803 through the long groove at the bottom of the outer cylinder 805, and the dust auger 803 will transport most of the rice grains in the screening frame 701 to the top of the outer cylinder 805 again, and break them up again through the conical cover 806, and then the impurities in the rice grains can be blown out for many times, playing a role in assisting impurity removal. When the rice grains enter through the short grooves of the outer cylinder 805, they will enter the bottom shell 1 through the discharge pipe 705. When there are not many rice grains, the rice grains will directly enter through the long and short grooves at the bottom of the outer cylinder 805 and enter the bottom shell 1 through the discharge pipe 705.

[0024] The impurity collecting mechanism 9 includes an eccentric wheel 901, the middle part of which is fixedly connected to the side of the rotating shaft 717 away from the rotating shaft 6, the side of the eccentric wheel 901 away from the bottom shell 1 is rotatably connected to a driving rod 902, the eccentric wheel 901 drives the driving rod 902 to move up and down, the top of the driving rod 902 is rotatably connected to a pushing rod 903, the outside of the top shell 2 is fixedly connected to an airbag 904, the pushing rod 903 can drive the airbag 904 to compress and expand, the top of the pushing rod 903 is fixedly connected to the bottom of the airbag 904, the bottom of the airbag 904 is fixedly connected to a one-way valve 905, and the top of the airbag 904 is fixedly connected to the bottom of the airbag 904. A one-way valve 906 is connected, and the one-way valve 905 and the one-way valve 906 can play a role of one-way ventilation. The outside of the bottom shell 1 is fixedly connected with a dust collecting tank 907, and the dust collecting tank 907 can store impurities. An exhaust pipe 908 is fixedly connected between the outer peripheral top of the dust collecting tank 907 and the one-way valve 905, and the exhaust pipe 908 plays a connecting role. The top of the dust collecting tank 907 is fixedly connected with a connecting pipe 909, and the outside of the top shell 2 is fixedly connected with an annular dust suction pipe 910, and the outside of the annular dust suction pipe 910 is fixedly connected with a connecting dust suction pipe 911, and the bottom of the connecting dust suction pipe 911 is fixedly connected to the top of the connecting pipe 909 When the rotating shaft 6 rotates, the rotating shaft 717 is driven to rotate through the active bevel gear 715 and the driven bevel gear 716, and then the eccentric wheel 901 is driven to rotate. After the eccentric wheel 901 rotates, the bottom of the driving rod 902 is driven to rotate. Since the top of the driving rod 902 is limited by the pushing rod 903, the top of the driving rod 902 moves up and down, and then the pushing rod 903 can be driven to move up and down. After the pushing rod 903 moves up and down, the airbag 904 can be compressed and deployed. When the airbag 904 is compressed, the one-way valve 1 905 is closed, and the one-way valve 2 906 is opened, and then the airbag 904 can be compressed. The gas is discharged through the one-way valve 906. When the airbag 904 is deployed, the one-way valve 905 is opened and the one-way valve 906 is closed. At this time, the air inside the dust collecting tank 907 is sucked away through the exhaust pipe 908, and then a pressure difference is generated inside the dust collecting tank 907, and then suction is generated inside the dust collecting tank 907. The suction is transmitted to the interior of the dust suction pipe 911 through the connecting pipe 909, and then transmitted to the interior of the top shell 2 through the connecting dust suction pipe 911 and the annular dust suction pipe 910, so that the impurities blown out by the dust blowing mechanism 8 can be sucked into the interior of the dust collecting tank 907, thereby completing the automatic cleaning of the rice, reducing the impurity content, and improving the accuracy of detection.

[0025] Working principle: after the rice grains are put into the top shell 2, the motor 4 is started, and the output end of the motor 4 rotates to drive the rotating shaft 6 to rotate, and the speed of the rotating shaft 6 is reduced by the reducer 5. After the rotating shaft 6 rotates, it drives the active bevel gear 715 to rotate, and the active bevel gear 715 drives the driven bevel gear 716 to rotate, and then it can drive the rotating shaft 717 to rotate, and the rotation of the rotating shaft 717 drives the elliptical disk 718 to rotate. Since the elliptical disk 718 is elliptical, it can drive the push-pull rod 719 to move up and down, and the push-pull rod 719 drives the screening frame 701 to move up and down. Therefore, when the rice grains enter the screening frame 701, the rice grains can be screened. At this time, the broken rice grains after screening enter the partition inside the bottom end of the bottom shell 1 through the filter on the screening frame 701. The complete rice grains in the screening frame 701 will enter the interior of the bottom shell 1 on the other side of the partition 706 through the discharge pipe 705. At the same time, the rotation of the rotating shaft 6 drives the longitudinal bevel gear 712 to rotate. After the longitudinal bevel gear 712 rotates, it drives the transverse bevel gear 710 to rotate, and then it can drive the rotating column 709 to rotate. The rotating column 709 drives the feeding auger 711 to rotate. At this time, the broken rice grains can be transported to the inside of one of the rice storage barrels 714, and the complete rice grains will be transported to the inside of another rice storage barrel 714 through another feeding auger 711. At this time, the mass of the broken rice grains and the mass of the complete rice grains can be weighed by the electronic scale 713, and then the broken rice rate of the rice can be calculated by the mass. When the rice enters the top shell 2, the motor 4 is started, and the output shaft of the motor 4 drives the fan 802 to rotate through the belt, so that the fan 802 can generate wind, and the airflow will enter the top shell 2 through the air guide 801. At this time, the rice will first be scattered by the conical cover 806, and the scattered rice grains are easier to use the airflow to blow up impurities in the rice grains. When the rice grains fall into the screening frame 701, the rotation of the rotating shaft 6 drives the dust auger 803 to rotate, and the dust auger 803 will transport the rice grains in the screening frame 701 to the top of the outer cylinder 805 again, and then be scattered by the conical cover 806 again, so that the impurities in the rice grains can be blown out multiple times; When the rotating shaft 6 rotates, the rotating shaft 717 is driven to rotate through the active bevel gear 715 and the driven bevel gear 716, and the eccentric wheel 901 is driven to rotate. After the eccentric wheel 901 rotates, the bottom of the driving rod 902 is driven to rotate. Since the top of the driving rod 902 is limited by the pushing rod 903, the top of the driving rod 902 moves up and down, and then the pushing rod 903 can be driven to move up and down. After the pushing rod 903 moves up and down, the airbag 904 can be compressed and deployed. When the airbag 904 is compressed, the one-way valve 1 905 is closed, and the one-way valve 2 906 is opened, so that the air in the airbag 904 can be released. The air is discharged through the one-way valve 906 when the airbag 904 is deployed, the one-way valve 905 is opened and the one-way valve 906 is closed. At this time, the air inside the dust collecting tank 907 is sucked away through the exhaust pipe 908, and then a pressure difference is generated inside the dust collecting tank 907, and then suction is generated inside the dust collecting tank 907. The suction is transmitted to the interior of the dust suction pipe 911 through the connecting pipe 909, and then transmitted to the interior of the top shell 2 through the connecting dust suction pipe 911 and the annular dust suction pipe 910, so that the impurities blown out by the dust blowing mechanism 8 can be sucked into the interior of the dust collecting tank 907, thereby completing the automatic cleaning of the rice, reducing the impurity content, and improving the accuracy of detection.
