Abstract
A boom for mounting to an agricultural sprayer comprises an elongate frame supporting a plurality of liquid application devices, liquid delivery means connected to the application devices, and an elongate tray attached to, and extending along, the boom. The tray is movable between a first position in which the tray extends substantially horizontally beneath one or more of the application devices to prevent material from leaking onto the ground below, and a second position in which the tray is located clear of delivery paths of the liquid application devices.
Claims20
A boom for mounting to an agricultural sprayer, the boom comprising:
- an elongate frame having an elongate axis extending substantially perpendicular to a normal forward direction of travel and supporting a plurality of liquid application devices;
- at least one pipe connecting the plurality of liquid application devices to a liquid storage tank;
- and
- an elongate tray attached to the elongate frame and extending substantially along an entire length of the elongate frame, the elongate tray spaced apart from the plurality of liquid application devices, wherein the elongate tray comprises:
- a first longitudinal edge proximate a forward side of the elongate frame and comprising a pivot axis parallel to the elongate axis of the elongate frame;
- and
- a second longitudinal edge opposite the first longitudinal edge;
- wherein the elongate tray is pivotally mounted to the elongate frame for movement about the pivot axis so as to pivot between a first position in which the second longitudinal edge is proximate a rearward side of the elongate frame such that the elongate tray extends substantially horizontally beneath the plurality of liquid application devices and forms a liquid-retaining receptacle to prevent liquid from leaking from the plurality of liquid application devices onto the ground below, and a second position in which the second longitudinal edge is located forward of and clear of delivery paths of the plurality of liquid application devices and the elongate tray extends downward to impact upon an airflow incident thereon as the sprayer moves across a field.
