METERING DEVICE

A metering device, e.g. for granular pesticidal materials has at the lower part of hopper 40 an oscillatory horizontal disc with compartments adapted first to receive granules at one position and then to discharge them at another, the granules passing down conduits 29 to a region 21 whence they are...

Beschreibung
Zusammenfassung:	A metering device, e.g. for granular pesticidal materials has at the lower part of hopper 40 an oscillatory horizontal disc with compartments adapted first to receive granules at one position and then to discharge them at another, the granules passing down conduits 29 to a region 21 whence they are expelled by an air-blast from bellows 38 and tube 20, an actuating handle 56 serving to generate the air blast only as material is discharged from the metering disc to region 21, this being achieved by bellows actuator 48 and disc oscillating means 54 both being connected to the axle 42 of handle 56 by means of connectors 44 and 46 respectively. The tubes 20 and 21 both slope upwardly at 5-25 DEG to avoid accidental discharge of granules.
