AI Technical Summary

Technical Problem

Current agricultural spraying systems on machinery like grape harvesters suffer from significant overhang, high center of gravity, complex adjustment mechanisms, and reduced work efficiency due to the need for complete boom folding during turns, especially when managing varying vegetation thickness and slopes.

Method used

Agricultural spraying units with independently controlled, vertically aligned spray product diffusion modules using parallelogram devices and telescopic arms, allowing for parallelism with vegetation, adjustable spacing, and adaptive management of slopes, reducing overhang and enhancing maneuverability.

Benefits of technology

The solution enables faster operation, reduced time loss during turns, and improved adaptability to varying vegetation conditions, maintaining efficient work speed and reducing machine dimensions.

Abstract

The present invention relates to a spraying unit (1), comprising a frame (2) for forming an agricultural spraying machine, and at least three spray product diffusion modules (50), and comprising: - for each spray product diffusion module (50), a movable arm (30, 40) configured to allow the spray product diffusion modules (50) to move relative to the carrier, - each arm (30, 40) being independently connected to the frame (2) by a parallelogram linkage configured to raise and lower the corresponding spray product diffusion module (50), and - each lateral arm (30) being mounted on the frame (2) via a pivot joint (P) in a vertical direction, to allow the deployment or retraction of the lateral spray product diffusion modules (50).
