Improved seed cleaner

The utility model belongs to the technical field of agriculture, and particularly relates to an improved seed cleaning machine which comprises a feeding hopper used for feeding, a first guide groove used for guiding seeds is formed in the bottom of the feeding hopper, a first hopper-shaped disc used for cleaning the seeds is arranged at the end, away from the feeding hopper, of the first guide groove, and a second hopper-shaped disc used for cleaning the seeds is arranged at the end, away from the feeding hopper, of the first guide groove. A second guide groove for guiding the seeds is formed in the bottom of the funnel-shaped disc I; the seeds rotate on the inner walls of the first funnel-shaped disc and the second funnel-shaped disc to generate centrifugal force, and the seeds with light weight are removed through the centrifugal force, so that the plump seeds with good quality can be sorted out, meanwhile, the seeds with light weight and heavy weight can be collected, subsequent use is facilitated, and the
