The second motor 12 is embedded in the top of the other side of the device body 1. Driven by the second motor 12, the sieve bucket 3 can be flipped, and then the larger particles remaining in the sieve bucket 3 are poured into the aggregate trough for collection. One end of the aggregate trough handle protrudes from one side of the device body 1 to ensure that the larger particles in the sieve bucket 3 can fall into the aggregate trough so that the larger particles can be collected.

[0022] Embodiment 3: A brush bar 6 is provided between adjacent scrapers 5, and both ends of the brush bar 6 are respectively welded to the turntable 4, and the brushes are arranged in a ring shape with equal spacing.
