ABSTRACT:
A litter screening and separating machine including a storage compartment, a loader at one end of the storage compartment for picking up encrusted litter material from the floor of a chicken house, a conveyor including a pair of chains for moving the encrusted litter from the loader to the storage compartment. A baffle plate adjacent to and beneath the conveyor chain prevents contamination of the conveyor chain. Vibrator rollers adjacent the pair of chains for engagement with tabs on spaced links of each chain for vibrating the loading flights. Trap doors beneath the upper run of the conveyor may be opened to permit some of the material collected to fall back to the floor of the poultry house. One can regulate the amount of material thus recycled by independently opening and closing the trap doors.
