However, the device does not integrate the cleaning device into the sowing equipment, which requires the staff to filter and clean the seeds in advance and pour them into the seeder. The steps are cumbersome and the efficiency of the sowing operation is reduced. Utility Model Content

The pitch circle diameter length of the driving gear 9 is smaller than the pitch circle diameter length of the driven gear 11. It is worth noting that by increasing the transmission ratio, the drum 10 can be rotated slowly, and the material can enter through the drop opening 20. At the same time, when the dusting work of the seeds is completed, the drum 10 can be driven to rotate by starting the first motor 3, so that the drum falls into the draw box 4;

[0024] A fixed plate 14 is fixedly installed in the drum 10, and a plurality of rotating shafts 17 are rotatably connected to the side of the fixed plate 14, and each rotating shaft 17 makes a circular motion with the center of the fixed plate 14, and a plurality of dust raising plates 18 are installed on the outside of each rotating shaft 17, and each dust raising plate 18 is arc-shaped, and each rotating shaft 17 rotates while revolving around the fixed plate 14, thereby stirring the seeds through each dust raising plate 18, and driving the seeds to move upward, and then fall down after moving a certain distance, and by repeatedly throwing and falling the seeds, dust and impurities are separated from the seeds, so that the dust can be adsorbed;

[0025] The fixed plate 14 drives each rotating shaft 17 to rotate and revolve through a planetary gear mechanism. The planetary gear mechanism includes a second motor 21, and the second motor 21 is fixedly mounted on the side of the fixed plate 14. The output shaft of the second motor 21 passes through the fixed plate 14 and is installed with a sun gear 19. A planetary gear 16 is installed on each rotating shaft 17, and each planetary gear 16 is meshed with the sun gear 19. A ring gear 15 is fixedly mounted on the outer side of the fixed plate 14, and each planetary gear 16 is meshed with the ring gear 15.
