pneumatic distribution system for pneumatically distributing material on a farm vehicle, and, agricultural implement

摘要

A pneumatic distribution system for pneumatically distributing material in an agricultural vehicle is described. In one example, the pneumatic distribution system comprises an air source having an outlet with different air pressures that defines a pressure gradient across the outlet and a plurality of inlet ports configured to receive air from the outlet to a plurality. timing chain comprising at least one first timing current with a first pressure drop value and a second timing current with a second pressure drop value that is greater than the first pressure loss value. the inlet ports for the first and second timing streams are located relative to the pressure gradient so that the second timing stream receives a higher air pressure than the first timing stream.
