Title: Spray device for plant protection solutions
Inventor: GRABER ALFRED
IPC: B05B9/03
Filed: 1985-07-08
Granted: 1989-01-19
Abstract: An apparatus for spraying plant-protective agents comprises a spray head having a motor, a spray plate mounted on the driving shaft of the former and a first container which is fastened to a lance. The container is connected via a connecting pipe line with a nozzle in the vicinity of the center of the spray plate. Diametrically opposite the mouth of the connecting pipe line in the container, a supply hose is connected with the first container which hose connects the latter container with a portable second container. Thereby, the relatively small first container can be refilled from the substantially larger second container. A large area can, therefore, be sprayed without having to handle the plant-protective agent. This reduces the danger of coming into contact with the plant-protecting agent. The apparatus is particularly suitable for the spraying of insecticides and fungicides.
