| 摘要 |
The invention relates to a treatment apparatus with light-weight structures, making it possible to perform spraying operations on diverse plots and crops requiring either protection or precision of application. It consists of a small carriage 1 of the wheelbarrow type, carried by at least one wheel 2 of a pump motor group 3 intended for supplying sprayed liquids, of an assembly of motor controls 6, 7, 8 within hand's reach, of regulation distributions 9, 10, 11, and diverse spraying devices, including an outdoor-type spraying boom for large surface areas to be sprayed without special precautions, a spraying boom with lateral protections 4 for precision spraying operations, and a lance with pipes for spraying operations at a distance. This assembly of combined devices, taking into account that the wheels placed in the centre, the spraying systems always placed at the front, permit, due to their light weight, quite exceptional ease of driving and guiding, regardless of the spraying tasks for which they are intended. <IMAGE>
