<p>A liquid spray head (10) e.g. to spray liquid for dust control or watering. The spray head has a body (11), an inlet (12) for receiving the liquid to be sprayed, a spray outlet, and at least one adjuster (15,16,17,18) arranged to adjust size and/or position of the outlet aperture such that a width or position of the aperture is variable, or both the width and position of the aperture are variable, relative to the body, to thereby deliver a desired rate, pattern or direction of liquid spray through the aperture. The adjuster can be ram (17,18) actuated controlling two coaxially aligned collar assemblies (15,16) with left and right adjusting leaves (25,26). A depth actuator works an outer body cover (24) to adjust vertical height of the outlet aperture. Spray aperture size and/or direction can be controlled based on vehicle speed and desired spray pattern/direction.</p> |
