Agricultural spraying machine frame suspension system - has two levers coupled by distorting link swinging on movable support

摘要

The suspension system is for the frame of an agricultural sprayer, having a movable direct support for the frame and a fixed support for the movable one. Two levers (27, 28) hinge on the movable support (2), lifting and supporting devices (46, 47) for the latter, and a distorting link (37 - 41) connecting them together. A spring (38) on the link acts against the levers in opposition to the lifting devices. The link can be formed by a horizontal telescopic arm, the spring acting between its two halves.
