Metering device for granular material and distribution machine having metering device

A metering device for granular material, in particular seeds and/or fertilizer, wherein said metering device comprises:

• a metering housing having at least one inlet and at least one outlet for said granular material and two side walls that are arranged spaced from one another;
• and
• a metering wheel with end faces each pointing toward said side walls, said metering when being arranged between, firstly, said inlet and, secondly, said outlet, and between said side walls, which are arranged spaced from one another, on a shaft and is connectable in a force-fit manner to the latter and can be driven to rotate by said shaft in a metering direction,
• wherein said metering wheel is associated with blocking means which are configured to block said metering wheel against the transport of granular material in a direction opposite to said metering direction from said inlet to said outlet and/or in said metering direction from said outlet to said inlet, wherein said metering device comprises a filling member comprising at least two plain wheels arranged in an unfastened manner on said shaft, wherein a plain wheel is arranged at each end face of said metering wheel and extends between said end face and said side wall, wherein a sealing element is arranged on both sides between said respective end face of said metering wheel and a side surface of said respective plain wheel pointing toward this end face, wherein said plain wheels each comprise a recess in the region of said outlet from said metering housing, and wherein said metering device is configured by way of at least one recess to eject granular material that is jammed between said plain wheel and said end face of said metering wheel.
