[0019] In this embodiment, the filter screen 4 is tilted toward both sides to ensure that impurities can be removed from both sides. Due to the tilt angle, the rice will remain vertically and will not flow out from the sides.

[0020] The rotation of the scraper 5 can prevent the rice from piling up on the surface of the filter screen 4 .

[0021] A support plate is provided at the bottom of the filter 4, a vibration spring is provided between the support plate and the filter 4, and a vibration motor is provided at the bottom of the filter 4, which further improves the situation that the surface of the filter 4 will not be accumulated or clogged by impurities.

[0022] The rice on the blanking plate 14 can be flattened by the limiting plate 15 to prevent the rice from piling up on the blanking plate 14 and making it difficult to perform the final step of impurity removal.

[0023] The rice to be cleaned is put into the impurity removal bin 1, and the rice is filtered through the filter 4. Large impurities are trapped on the filter 4. The scraper 5 rotates to prevent the rice from piling up on the filter 4. Then the rice flows to the rice-raising plate 18 through the guide plate 10.

[0031] In this embodiment, by starting the motor 13 to drive the rotating shaft 12 to rotate, the rice-raising plate 18 can be driven to rotate, so that the rice can be thrown up to raise the dust.

[0032] Furthermore, the first dust collection hood 11 and the second dust collection hood 16 extend outwards through a pipe and are connected to a dust collection assembly.

[0033] In this embodiment, the first dust hood 11 is used to collect dust and tiny impurities generated during the process of rice being thrown up and falling. These impurities are sucked into the dust collection duct under the action of the airflow and transported to the dust collection assembly.

[0034] It is installed on or near the blanking plate 14 to further collect tiny impurities remaining in the rice after the impurity removal process. These impurities are also sucked into the dust collection pipe under the action of the airflow and transported to the dust collection component.
