A spraying member mounted on a platform able to be oriented in all directions, both in vertical and horizontal planes. The member may be carried by any moving machine having hydraulic pressure installation and preferably a telescopic hinged arm which allows the spraying member to approach the surface to be sprayed or treated. The spraying member can spray areas above, on, or below the ground level since it is pivoted about three orthogonal axes. The spraying device is appropriate for insecticidal and herbicidal treatments, or for the spreading of fertilizers.

A device for spraying a liquid which comprises in combination: a vehicle adapted to travel along a site to be sprayed; an arm articulated to said vehicle and provided with means enabling a free end of said arm to be moved to a location below said vehicle, to a location above the level of said vehicle and to selective locations between said locations above and below said vehicle; a support member pivotally connected with said arm for rotation relative thereto about a substantially horizontal first axis, said arm and said member being interconnected by means for rotating said member about said first axis; a platform journalled on said member for rotation relative thereto about a substantially horizontal second axis orthogonal to said first axis; and an atomizing head mounted on said platform for angular displacement thereof about a third axis substantially orthogonal to said first and second axes, said head being provided with means for dispensing an atomized spray of said liquid in a pattern having a further axis substantially orthogonal to said third axis.
