Spray pulsing nozzle flow control using rotational step positions

摘要

SPRAYER PULSING NOZZLE FLOW CONTROL USING ROTATIONAL STEP Abstract of the Disclosure 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 10 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 15 and field and crop conditions so as to maintain a desired spray application rate. 50/ Ground Speed 10 Sensor22 52 - - / ~' r 42 44 40 Spray Data Input Contolle Motor Fluid Tank Device rController 56 48 -38 34 20 GPSStpe 46 Receiver Motor 30 - 3618 FIG. 1 14 3 2 - 2 4 -2 L----r58 ' 64 64
