Abstract
Spraying apparatus (1) is provided that has two horizontally disposed upright spray arm assemblies (33) that each carry sprayers (43). Each spray arm assembly (33) has a sprayer (43) in an upper part (35) and a sprayer (43) in a lower part (37). The upper part (35) is able to move relative to the lower part (37) so the axis of spraying from the upper part (35) will be downwardly directed towards an upper part of crop to be sprayed. The spray arm assemblies (33) are mounted on respective arms (25) for moving laterally inwardly or outwardly relative to a longitudinal direction of a row of crop to accommodate for different width crops and/or different crop row widths.
Claims10
Spraying apparatus for spraying agricultural crops, particularly but not exclusively fruit trees, planted in adjacent rows where the apparatus will, in use, pass between adjacent rows in a direction parallel to the rows,
- said apparatus having two horizontally spaced upright spray arm assemblies each with sprayers attached thereto, one spray arm assembly, in use, holding sprayers facing one row of the crop and the other spray arm assembly, in use, holding sprayers facing an adjacent row of the crop,
- each spray assembly having a sprayer in an upper part, and a sprayer in a lower part,
- spray arm assembly first moving means able to move an upper part of at least one of the spray arm assemblies relative to a lower part of the spray arm assembly so a central axis of spraying from the sprayer in the upper part will be directed in a downward direction toward an upper part of the crop,
- and spray arm assembly second moving means able to move the upper part and the lower part of at least one of the spray arm assemblies as a whole laterally inwardly or outwardly relative to the longitudinal direction of the row to accommodate for different width crops and/or different crop row widths.
Apparatus as claimed wherein said supporting arms can be swung to be generally parallel to one another and wherein the length of the supporting arms is such that when swung to this condition, both spray arm assemblies will be positioned at a rear of the apparatus behind a tank for spraying liquid carried by said apparatus, whereby to minimise the width dimensions of the apparatus to facilitate movement of the apparatus when spraying is not being performed.
