ABSTRACT:
In a new spraying apparatus a spray boom structure supporting the spray dispensers for liquid or finely divided spray material is supported by an air pressured flexible bag skirt attached to the structure and forming an enclosure into which the spray dispensers discharge to minimize drift of the sprayed material and permitting increased speed of the apparatus over the ground. The bag skirt structure also "averages out" irregularities in the surface so that a more uniform spray pattern is achieved. Air is fed into the enclosure from the leading bag skirt part via an elongated aperture close to the ground and from the trailing bag skirt part from an elongated aperture close to the enclosure roof. The weight of the fan and its housing supplying the pressurized air is supported separately from the boom. The boom structure may comprise hinged portions that can be moved to a vertical storage position, and it may also include arcuate downwardly extending support members. The bag skirt structure is supported from the frame consisting of parallel rods and cross-members by loops of material through which the rods pass.
