1. A metering device (10) for an agricultural machine (12) for outputting granular solids from a storage container (14) through a conveyor system (18) to a dispensing unit (16), comprising:
a metering housing (20), wherein the metering housing (20) comprises
a first mounting flange (22, 52) on a storage container side or on a conveyor system side,
an inflow opening (24) for the granular solids, and
a discharge opening (26, 108) for the granular solids,
wherein the first mounting flange (22, 52) is formed as a polygon or circular,
wherein a metering chamber (28) is formed inside the metering housing (20),
wherein a conveyor device (32) rotating about a rotary axis (30) is arranged between the metering chamber (28) and the conveyor system (18),
wherein the conveyor device (32) separates the inflow opening (24) and the discharge opening (26) in a pressure-tight manner,
wherein the metering housing (20) is formed out of two substantially mirrored or identically shaped sub-bodies (58, 60),
wherein a separating plane (56) of the sub-bodies (58, 60) of the metering housing (20) is substantially arranged at an angle to the rotary axis (30), and
wherein the metering housing (20) comprises a drain opening (62) which is arranged in the separating plane (56) of the sub-bodies (58, 60) of the metering housing (20).
