Device, method, meter housing and agricultural implement for airflow assisted feeding of granular material in an agricultural implement

Method for airflow-assisted feeding of granular material in an agricultural implement, comprising:

• providing a material pickup zone, the extension of which, viewed in the horizontal plane, is defined by a roof above the pickup zone,
• providing an airflow through the material pickup zone in a direction towards an outlet from the material pickup zone,
• feeding the material by gravity to the material pickup zone, so that the material slides into the material pickup zone in a direction across the airflow,
• providing an air inlet valve comprising a valve seat and a valve body, wherein the valve body has a first part which is substantially cylindrical and a second part which comprises a recess forming a channel across a geometric axis, wherein the second part can be aligned with the air inlet;
• turning the valve body about the geometric axis which is substantially perpendicular to a flow direction at the air inlet so as to control a flow area for the airflow to the material pickup zone, and
• conducting the material-laden airflow from the outlet to at least one distribution unit.
