Dispenser for seeds and fertiliser - has injector valve near dispensing pipe inlet to include quality of pesticide

摘要

The seed or fertiliser dispenser comprises a storage tank (1) with outlet openings through which the seeds pass via rotary adjustable-speed metering elements (4) into dispensing pipes (11, 11') connected to a fan. Near the inlet opening of each dispensing pipe is an injector valve, and at their spaced outlet openings disposed perpendicularly to the direction of travel are dispensing elements. A second tank is also provided with outlet openings, and contains material which is passed via rotary adjustable-speed metering elements to each dispensing pipe. The outlet openings and metering elements of both tanks are formed into groups of the same number.
