Pneumatic seed metering with self generating pressure difference, and method for controlling the pressure difference in the feeder.

摘要

Pneumatic seed metering with self generating pressure difference, and method for controlling the pressure difference in the injector.This refers to a new system of seed (10) of the pneumatic type, which is used as an integral part of agricultural equipment for sowing crops, also known as machines, planters, and method for controlling the pressure difference in the feeder.It comprises a vacuum generating turbine which comprises a rotor (15) provided between a vacuum chamber (12) and a circular compartment (11), which is provided with an air outlet (16), and the rotor (15) is driven by a motor (14) is fixed externally in one of the ext Remidades of said feeder (10).At its tip is provided for a silo (18) in fluid communication with the interior of the feeder. The injector comprises a disc (24) with holes (24a), which is equipped with an organizer of seeds (25) positioned on the rim of said disk, which is disposed between said vacuum chamber (12) and the fixed side (17) of the feeder, in which a shaft (19) is responsible for moving the disk (24 ). 1 / 1
