DEVICE FOR SELECTIVE AND CONTROLLED ELECTRIC WEEDING

摘要

The invention concerns a device for electric weeding of plants, such as adventive plants, in cultivated lands, comprising an electric power source (1) whereof one terminal is electrically connected to earth by a ground electrode (5) and the other is connected to at least one active electrode (4a) for destroying plants by sending on them an electric discharge, said active electrode (4a) being mounted projecting at the end of the control member (2) for bringing said electrode (4a) selectively towards a plant identified for destruction, the electric power source (1) capable of generating an electric arc when the electrode (4a) comes in the proximity of the plant to be destroyed or in contact with it. The invention is characterised in that the device comprises an electrocution bell consisting of the active electrode (4a) projecting at the end of the control member (2) and a protection chamber (3a) enclosing the active electrode (4a) fixed to said control member (2) end. The invention is applicable to weeding plants such as adventive plants.
