ROTARY WICK WIPER APPARATUS FOR TREATING PLANTS

摘要

The invention provides a rotary wick wiper apparatus (10) for plants, of the type wherein a rotor assembly (12) is operatively connected to means (15) whereby it may be rotated about an axis (13) disposed substantially vertically in use, the rotor assembly having wick means (17) beneath it for plant-wiping function and arranged to receive liquid from a reservoir (19) above the bottom of the rotor assembly (12) and movable with the rotor assembly; characterised in that the reservoir (19) has an air vent (28) on a portion thereof which is normally elevated and disposed inwardly relative to the rotor assembly axis of rotation, said air vent (28) being connected to one end of an air tube (29) of small diameter extending circuitously around the rotor assembly (12) and having its other end providing an air-intake opening (33) on a part of the rotor assembly disposed outwardly of said air vent (28) relative to the said axis of rotation (13).
