Collecting apparatus primarily for catching and elevating, for example, live birds in a deep litter or open house situation

摘要

Collecting apparatus for catching and elevating animate or inanimate objects comprises a mobile supporting framework mounting two elongate members (14 or 20,21, or 30,31) adapted to be driven counter to one another and disposed with their axes parallel to one another and in use, to a supporting surface (9) across which the framework is intended to be moved. The members define therebetween a passage. Means (16) lesser in length than the passage is deep outstand from around the members. The elongate members (14, 21, or 31) rearward in the direction in which the framework is intended to be moved is nearer ground level (9) than the elongate member (14,20 and 30) then to the front such that the ground clearance at the forward member enables passage of an object therebelow while that at the rear member prevents such passage and ensures that the means (16) thereon, in co-operation with the means (16) on the forward member, sweep the members (14, 20,21 or 30,31) and elevates the object or objects to the upper end of the passage for discharge therefrom to the next step in a series of steps.
