Multiple nozzle body

摘要

A multiple nozzle body including a plurality of discharge nozzles for arranging on the liquid line of an agricultural crop sprayer, wherein the liquid line can be connected to the supply line of the multiple nozzle body, wherein the supply line opens out in a distribution space, wherein a plurality of connecting lines that respectively lead to a discharge nozzle branch off from the distribution space, wherein a shut-off element that is respectively assigned to a connecting line and is formed as a shut-off valve is assigned to the distribution space, wherein one or more connecting lines can be optionally connected to and/or shut off from the supply line by means of the shut-off element of the shut-off valves, which can be actuated by means of a switchable actuating element.

1. A multiple nozzle body, comprising a plurality of discharge nozzles to be arranged at a liquid line of an agricultural crop sprayer, a supply line for the multiple nozzle body adapted to connect to the liquid line, the supply line opening in a distribution space, a plurality of connecting lines each leading to one of the plurality of discharge nozzles and branching off, via a branch-off opening, from the distribution space, in the distribution space each of the plurality of connecting lines is assigned a shut-off element formed as a shut-off valve, one or more of the plurality of connecting lines is selectively connected to or shut off from the supply line by means of the respective shut-off element, the shut-off elements being actuatable by means of a switchable actuating element, the actuating element including a plurality of switching cams and turnable about an axis of rotation into different switching positions, the shut-off elements being of a spherical form thereby forming spherical shut-off elements and in their sealing position arranged in a valve seat which comprises a sloping annular portion and is arranged at the respective branch-off opening of the respective connecting line, and the spherical shut-off elements movable by one or more of the plurality of switching cams in an at least approximately perpendicular direction to the axis of rotation of the actuating element and in an at least approximately parallel direction to the respective branch-off opening over an oblique wall of the sloping annular portion of the valve seat out of the valve seat into a position releasing the throughflow to the respective connecting line.
