System for maintaining the horizontal position of spraying ramps in sprayers.

摘要

The invention refers to a system that maintains the horizontal position of spraying ramps in sprayers used for field crops, in order to apply chemical treatments with fungicides and herbicides, as well as with liquid chemical fertilisers with a low vapour pressure. According to the invention, the system ensures the horizontal position of the spraying ramps (D) mounted in a central pivot (1) with the help of a pin (10) and of some plates (9). Vertical stabilisation and limitation of oscillation are ensured by a profiled plate (11), a pin (12), a roller (15) and a stop (16), whilst horizontal stabilisation in the forward direction is ensured by a support bracket (13) and a friction plate (14).
