NOVELTY - Equipment extracting bulk organic matter from composting tunnel, locates conveyor (2) between reciprocating floor (4) and drive unit (3).    USE - Equipment extracting bulk organic compost from a composting tunnel.    ADVANTAGE - This design is simplified in comparison with prior art, and is more economical in construction. Functionality is improved and long-term trouble-free operation is assured. Contamination of the drive units and consequent unreliability are avoided by their location remotely from the end of the tunnel. The drive rods form a grid through which the compost can fall onto the conveyor. The reciprocating floor unit is moved to serve a number of composting tunnels.    DETAILED DESCRIPTION - Equipment extracting bulk organic matter from composting tunnel, locates conveyor (2) between reciprocating floor (4) and drive unit (3). Each base plate (5) of the reciprocating floor (4) is connected by a coupling rod (8, 17) to a linearly-reciprocating, preferably hydraulic drive unit (6). Each coupling rod is connected permanently to its respective base plate and detachably with the drive unit. Alternatively, each is fixed to the drive unit and detachable from the base plate. Coupling rods lie parallel, with mutual clearance. The conveyor unit is arranged immediately in front of the tunnel end. It is inside the tunnel, in the end region allocated to the drive unit. It is in a channel depression, orientated transversely with respect to the length of the tunnel (1). The conveyor is constructed as a trough- or belt conveyor. A loosening- or compost-turning roller (11, 12) can be brought into contact with the compost, swung into the front of the tunnel. It can be moved parallel to the length of the conveyor, on a trolley (70) to which it is attached. The coupling rods are connected by interlocking with the base plates or with the hydraulic piston of the drive unit. The loosening roller is in the drive unit.
