Size grading sorting machine for round fruits - conveys fruits along gravity discharge gap of increasing adjustable width

摘要

The fruits are conveyed longitudinally by a flat belt inclined laterally at 20 degrees to the horizontal. The fruits are initially prevented from rolling off the lower side edge of the belt by a sizing rail (A) supported in a plane at 90 degrees to the plane of the conveyor belt. The spacing between the sizing rail and the belt leaves a gap which increased progressively in the direction of belt travel. Smaller fruits escape through the gap before larger fruits. The gap angle and width are adjustable.
