Abstract A collection bin on a mobile fruit harvester wherein a chute is pivotally mounted on the bin to close a discharge opening when the chute is in an upright position. A latch releasably holds the chute in the closed position. An actuator assembly is mounted on the chute in operative connection with the latch and includes a panel projecting beneath the chute so as to be engageable by a receiving bucket mounted on a vehicle.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
159 words
In a material-collection bin having a wall through which an opening is defined for discharge of material from the bin, wherein the improvement comprises: a discharge chute pivotally mounted on said bin for movement about a horizontal pivot axis between a generally vertically disposed position closing said opening and a downwardly inclined position permitting discharge of material through said opening along said chute; spring means interconnecting said chute and said bin for biasing said chute into its closed position; a latch pivotally mounted on said chute for releasably engaging said bin to hold said chute in its closed position; a panel pivotally mounted at its upper edge on said chute and projecting downwardly therefrom; a rod fixed on said panel and extending upwardly therefrom in operative connection with said latch, whereby said latch is released from connection with said bin in response to pivotal movement of said panel to thereby free said chute for movement to its discharge position.
