DOSING SYSTEM OF PNEUMATIC TROLLEY Russian patent published in 2016 - IPC A01C7/08 

FIELD: agriculture.

SUBSTANCE: invention relates to metering and product feed to agricultural machine by means of air flow. Agricultural cart in one version includes product metering system and air source connected to system of metering product and configured to transfer agricultural product to agricultural machine by means of air flow. Product metering system comprises an auger assembly extending substantially along axis, not parallel to horizontal plane and not perpendicular to horizontal plane, and retaining chamber. Latter can reduce pulsations in agricultural product from auger assembly. Auger assembly comprises drive shaft, auger face arranged around drive shaft and extending from inlet to retaining chamber. Auger face is arranged to transfer agricultural product from inlet hole to retaining chamber during rotation of drive shaft. Retaining chamber is configured for accumulation of agricultural product until agricultural product reaches outlet hole and comes from auger assembly. Another version of agricultural cart includes in addition to said elements of first version a storage container configured for storing agricultural product, connected to agricultural product metering system. Metering system consists of multiple auger assemblies configured to transfer agricultural product to corresponding plurality of main pipelines.
