[0002] The existing large-leaf crop sorting equipment on the market has a basic structure consisting of a feeding belt line, a detection station, and several groups of independently swingable sorting belt lines. The sorting is carried out by swinging the sorting belt lines up and down. The swing of the sorting belt lines is basically driven by large-diameter cylinders on both sides.

[0003] A manual loading system is provided in front of the feeding belt line. The belt line drives the large-leaf crops through the visual inspection station, and then transports them backward through multiple sets of independently swingable grading belt lines. At the corresponding bin belt line, the grading belt line is controlled by the cylinder to swing downward, and the large-leaf crops are transported to the corresponding grading station. The belt line is then swung straight by the cylinder to transport the subsequent large-leaf crops forward for subsequent grading actions.

[0004] In the existing grading device, the equipment has several groups of independent swinging belt lines, each group of belt lines is independently powered, and large-diameter cylinders on both sides drive it to swing up and down, which makes the cost of the entire equipment line high; the equipment as a whole adopts a straight conveying form, and multiple groups of grading belt stations are connected in series, which occupies a large area.
