SPRAYER PULSING NOZZLE FLOW CONTROL USING ROTATIONAL STEP POSITIONS |
摘要 |
An agricultural sprayer spray head is adapted for being mounted to a spray boom together with a plurality of like, equally spaced spray heads. Each spray head includes a body containing a flow control member mounted for rotation about an axis and including a fluid control passage arrangement located for effecting an intermittent connection between a fluid inlet leading to, and an outlet leading from the body as the control member is oscillated or rotated by a powered motor so as to effect a pulsing flow through said control passage arrangement. The powered motor operates at a speed controlled by various input parameters including vehicle speed and field and crop conditions so as to maintain a desired spray application rate.
