Field sprayer and spreading boom for a field sprayer

摘要

The present invention relates to a field sprayer (1) with a delivery boom (2) and a frame (3). The Ausbringausleger (2) can be moved between an application position and a transport position and has a plurality of elements. At least two adjacent elements are at least pivotally connected to each other via a joint with a hinge axis (5). The plurality of elements (4) are swung in the application position so that the hinge axis (5) is substantially perpendicular to a yaw axis of the field sprayer (1) and the plurality of elements are arranged in the transport position so that the hinge axis (5) substantially is arranged parallel to the yaw axis of the field sprayer. The delivery boom (2) and a rotation-lifting mechanism (6) are connected to the frame (3), the rotation-lifting mechanism comprising an arm (7), a first actuator (10) and a second actuator (11). The arm is connected at its first end (8) to the frame (3) of the field sprayer (1) and at its second end (9) with the Ausbringausleger (2). The first actuator (10) is connected to the arm (7) and the frame (3) and the second actuator (11) is connected to the Ausbringausleger (2). Actuation of the first actuator (10) may raise and lower a second end (9) of the arm (7) relative to the frame, and actuation of the second actuator (11) may surround the applicator arm (2) about the second end (9) of the second actuator Turn arms (7). The Ausbringausleger (2) can be rotated by an actuation of the second actuator (11) to the deployment position and the transport position.
