[0029] See also Figures 1 to 6, which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:

[0030] A material guide plate 31 is provided on the side of the storage bin 3 close to the screening bin 2, and an array of matching holes 32 are opened on the side of the material guide plate 31 close to the conveying tube 42. The matching holes 32 are semicircular holes, which form a complete circle with the holes on the conveying tube 42 to facilitate the smooth delivery of seeds. A dividing plate 6 is provided inside the screening bin 2, and an array of partition plates are arranged on the dividing plate 6. The distance between each two partition plates is slightly smaller than the diameter of the matching holes 32, so that the seeds can slide on the dividing plate 6. When dry or incomplete seeds roll down, they will fall onto the collecting plate 63 from the gap between the partition plates, and the dividing plate 6 and the conveying tube 42 are in close contact with each other.

[0031] A guide plate 61 is provided on one side of the dividing plate 6. The guide plate 61 has an inclined angle and is used to collect and transport seeds with full quality. A discharge pipe 62 is provided at one end of the guide plate 61. The discharge pipe 62 is used to send the seeds out and drop them on the field. A collecting plate 63 is provided on the side of the dividing plate 6 away from the guide plate 61. Oblique plates 64 are symmetrically provided on the collecting plate 63. The oblique plates 64 are used to gather the dry, flat and incomplete seeds that fall on the collecting plate 63, so that the collecting box 7 can collect these seeds conveniently. A collecting box 7 is provided inside the screening bin 2.

[0032] An armrest 11 is provided on one side of the moving seat 1 , and a handle 12 is provided on the armrest 11 . The handle 12 is used for hand-held pushing.
