Abstract:
1. A bin lid assembly for association with a bin opening of an agricultural particulate material storage bin including a peripheral side wall and a roof supported on the side wall which locates the bin opening therein, the bin lid assembly comprising: a lid member arranged to span across the bin opening; a hinge arranged to support the lid member on the bin for pivotal movement about a hinge axis offset to one side of the bin opening between a closed position in which the lid member extends forwardly across the bin opening from the hinge axis and an open position in which the lid member is pivoted relative to the closed position such that the lid member extends rearwardly from the hinge axis away from the bin opening in the open position; a biasing member arranged to bias the lid member towards the closed position; an operating linkage pivotally connected to the lid member; an actuator tether arranged to extend upwardly alongside the bin towards an upper end of the actuator tether which is arranged for connection to the operating linkage; the operating linkage including an opening arm extending in a longitudinal direction between an inner end of the opening arm which is pivotally connected to the lid member and an outer end of the opening arm which is opposite the inner end so as to be arranged for connection to the upper end of the actuator tether; the opening arm being supported for pivotal movement with the operating linkage relative to the lid member between a first position in the closed position of the lid member in which the opening, arm extends generally upwardly away from the lid member from the inner end to the outer end and a second position in the open position of the lid member in which the opening arm extends generally rearward in relation to the hinge axis from the inner end of the opening arm to the outer end of the opening arm.
