Solid waste treatment device used after rigid polyurethane foam processing

The invention discloses a solid waste treatment device used after rigid polyurethane foam processing, and relates to the field of rigid polyurethane foam solid waste treatment. A driving motor; a first gear; a second gear; a first crushing roller and a second crushing roller; comprising a guide plate; and a discharging mechanism. Through the arrangement of the downward pressing mechanism, when the lower portion of an L-shaped material is completely crushed, the material continues to move downwards under the action of a conveying roller, and a second rack moves under the action of external force till a third gear does not make contact with a sixth gear any more; a push rod on one side of a second rack pops up under the action of a spring to provide pushing force for the material, so that the material is separated from a conveying roller and falls between a first crushing roller and a second crushing roller, and meanwhile, a pressing rod slides downwards under the action of gravity to be in contact with the out
