An attachment means for the spray boom of a field sprayer

摘要

An attachment means for the spray boom of a field sprayer, includes a basic frame 1-3 which is connected to the field sprayer and on which frame the spray boom 5 is mounted via pivot joint members in such a manner that it is pivotable to a limited extent both in the horizontal plane and in the vertical plane, the pivotal axis for the pivotal movement in the vertical plane extending in the intended direction of travel and being disposed above the centre of gravity of the spray boom. In order to substantially simplify the complex structure for the mounting of the spray boom, whilst simultaneously substantially improving the vibrational behaviour of the spray boom, the vertical pivotal axis (15) for the pivotal movement in the horizontal plane is disposed at least approximately in the centre of gravity plane of the spray boom (5), and the mounting for the spray boom (5) on the basic frame (1) has bearings (12, 13) which are spaced from each other in the direction of travel (7).
