Abstract
The agricultural chemical applicator of the present invention comprises a roller frame assembly having folding wing sections at opposite ends thereof. Rollers are mounted on each of the frames and include a liquid absorbing material which receives an agricultural chemical from a dispensing conduit located above the roller. A wiper engages the roller to prevent excess liquid from dripping off of the roller. The rollers are connected for driving engagement by interlocking lugs at the ends of the rollers adjacent the hinged joints of the roller wings.

An agricultural chemical applicator comprising:
- a roller frame assembly having at least first and second elongated frame sections;
- each of said frame sections having an elongated roller rotatably journaled therein for rotational movement about a rotational axis, said roller having an outer cylindrical surface covered with a liquid absorbing material;
- hinge means interconnecting said first and second roller frame sections for articulated swinging movement from a straight position wherein said rotational axes of said rollers of said first and second frame sections are in approximate registered alignment to a folded position wherein said rotational axes are articulated with respect to one another;
- each of said rollers having lug means connected thereto and positioned adjacent said hinge means;
- said lug means of said roller of said first frame section being positioned to engage said lug means of said roller of said second frame section when said frame sections are in said straight position whereby rotational movement of one of said rollers will be transmitted to the other of said rollers;
- power means connected to said one roller for rotating said one roller;
- chemical dispensing means mounted to said frame sections above said rollers and being connected to a source of liquid chemicals for dispensing said liquid chemicals onto said liquid absorbing material on said rollers;
- wiper means mounted on said frame sections and functionally engaging said liquid absorbing material of said rollers for wiping excess liquid chemical therefrom to prevent said chemical from dripping off said rollers.
