Spraying equipment, for example for applying herbicide, comprises a spraying head (6) mounted on one end of a support tube (2), the other end of which is adapted to be held by an operator. The spraying head (2) comprises a body (48) which accommodates an electric motor (50) and an atomising disc (54) which, in operation, is driven by the motor (50). Liquid is supplied to the disc (54) through a supply tube (38) and power is supplied to the motor (50) through a lead (36). The tube (38) and the lead (36) are accommodated within the support tube (2). Upon rotation of the disc (54), fluid is ejected by centrifugal force from the periphery of the disc (54) after being subjected to a wiping action as it passes through a narrow gap (68) between the disc (54) and the body (48). This wiping action spreads the fluid evenly around the disc (54). |
