ABSTRACT:
A vibrating, moving, endless screen for separating earthworms from worm castings and bedding. An endless belt fabricated from a screen is placed on an incline and moved upwardly in the direction of the incline. A portion of the moving surface is vibrated and a mixture of worm bedding, castings and earthworms is placed along the upper surface. The worms are conveyed over the upper end of the belt. The worm castings and bedding fines pass through the belt and the larger bedding material passes downwardly over the screen surface and passes over the lower end of the moving endless belt.
