Metering device for granular material and distribution machine having metering device

Abstract

The invention relates to a metering device () for granular material, in particular seeds and/or fertilizer, where the metering device () comprises a metering housing () having at least one inlet () and at least one outlet () for the granular material and two side walls () that are arranged spaced from one another, where a metering wheel () with end faces () each pointing toward the side walls () is arranged between, firstly, the inlet () and, secondly, the outlet (), and between the side walls (), that 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 the shaft in a metering direction (D), where the metering wheel () is associated with blocking means () which are configured to block the metering wheel () against the transport of granular material in a direction opposite to the metering direction (D) from the inlet () to the outlet () and/or in the metering direction (D) from the outlet () to the inlet (), and a plain wheel () is arranged at each end face () of the metering wheel () and extends between the end face () and the side wall () in an unfastened manner on the shaft, where a sealing element () is arranged on both sides between the respective end face () of the metering wheel () and a side surface () of the respective plain wheel () pointing toward this end face ().
