  • Plant protection discharge apparatus
    Patent number: 5002227
    Abstract: A discharge apparatus (1f) for treatment media has cabin-like discharge units (3f) bounding in each case a passage (4f), which are in each case provided with at least one discharge device (10f) for the treatment medium, at least one air-carrying back suction device (17f) for the treatment medium not absorbed by the plants (2f) and a compressed air device (13f) for producing both a turbulence air flow (65) and air curtains. The back suction device (17f) can operate directly or indirectly in circuit with the compressed air device (13f). Thereby benefits are achieved for operating and processing with low consumption of treatment medium despite high velocity of operation.
