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.
Claims35
A discharge apparatus for plant treating purposes, for agricultural standard row crops, comprising:
- at least one discharge unit provided to be moved in at least one advance direction over a row of plants, said discharge unit providing at least one treatment zone defining at least one boundary of a passage for the plant row to be treated with a treatment medium;
- drive means for producing at least one substantially oriented treatment stream traversing said treatment zone between at least one stream outlet and at least one stream inlet;
- and,
- at least one return means for receiving at least part of said treatment stream from an area of the treatment zone, and for returning said treatment stream back to an area of said treatment zone,
- wherein said return means are provided for returning at least part of at least one primary treatment stream traversing said treatment zone oriented towards said boundary by guiding at least said part as a continuing and oriented zone-traversing secondary treatment stream back into said treatment zone by subsequent free flow deflection of said treatment stream at said boundary of said treatment zone.

A discharge apparatus for plant treating purposes, for agricultural standard row crops, comprising:
- at least one discharge unit provided to be moved in at least one advance direction over a row of plants, said discharge unit providing at least one treatment zone forming a passage for the row of plants;
- discharge means for a treatment medium associated with the treatment zone;
- at least one blower means for producing a treatment stream;
- and,
- at least one return means provided for returning at least part of discharged treatment medium from an area of the treatment zone, said return means being constructed for sucking connection to at least one of said at least one blower means, and wherein at least one blower outlet directed into the open of the treatment zone and at least one diverting means for deflecting at least one treatment stream into a return stream face one another transverse to at least one advance direction of the apparatus, at least one blower outlet being located adjacent to at least one return sucking inlet for said return stream, said diverting means having at least one diverting inlet associated with and spaced in the advance direction with respect to at least one blower outlet in a spacing in the advance direction, said diverting means having at least one deflecting outlet leading into the open of the treatment zone and directed counter to at least one return sucking inlet, an additional blower outlet being located directly adjacent to said deflecting outlet, said additional blower outlet leading into the open of the treatment zone for producing an accelerating air flow intersecting said return stream and directed towards the return sucking inlet.

2 more elements
A discharge apparatus for plant treating purposes, for agricultural standard row crops, comprising:
- at least one discharge unit provided to be moved in at least one advance direction over a row of plants, said discharge unit providing at least one treatment zone defining at least two opposite boundaries forming a passage for the plant row to be treated with a treatment medium;
- drive means for producing at least one substantially oriented treatment stream traversing said treatment zone between at least one stream outlet and at least one stream inlet for each treatment stream;
- at least one return means for receiving at least part of said treatment stream from an area of the treatment zone and for subsequently returning said treatment stream to an area of the treatment zone, wherein at least at one boundary of at least one said at least one treatment zone a primary stream outlet issuing into said treatment zone is directed towards a spacedly facing primary stream inlet located in the vicinity of an opposite boundary and directly connected by a deflecting duct means to a secondary stream outlet separate from and opposite to said primary stream outlet, said secondary stream outlet being directed back into said treatment zone and said deflector means connecting said primary stream inlet and said secondary stream outlet in the vicinity of said opposite boundary.
