US Patent 9549505 Agricultural vehicle conveyance linkage

In one example, a conveyance system comprises a conveyance mechanism and a linkage configured to movably couple the conveyance mechanism to a vehicle, wherein the conveyance mechanism is coupled to the linkage at a first connection mechanism and configured to pivot about a pivot point. The conveyance system comprises a vertical movement mechanism configured to move the first connection mechanism in a substantially vertical direction, and a tilt movement mechanism comprising a tilt actuator configured to pivot the conveyance mechanism about the pivot point. A second connection mechanism couples the tilt actuator to one of the conveyance mechanism or the linkage and allows a defined range of tilt movement of the conveyance mechanism that is independent of actuation of the tilt actuator.
