The leaf stripping conveying device is equipped with multiple sets of conveying wheels driven by the engine through mechanical transmission parts in the housing and Multiple sets of stripping wheel sets, conveying wheel sets and stripping wheel sets are arranged in the housing in a certain order. Each set of conveying wheels is composed of two conveying wheels arranged up and down; each group of stripping wheels is composed of two stripping wheels respectively arranged above and below the sugarcane conveying channel. For stripping and conveying to the rear, the stripping wheel is composed of a drum-shaped wheel core and a plurality of brushes connected to the wheel core. The outer edge of the stripping wheel brush is provided with elongated teeth. Usually, two sets of stripping wheels are provided in the stripping conveying device. In order to discharge the peeled sugarcane leaves, the housing is provided with an opening below the two sets of stripping wheels, and the leaves brushed by the stripping wheels are discharged from the openings. .

At present, due to the limitation of the technical level of sugarcane harvesting machinery in our country, a cluster of multiple sugarcanes is often fed together during the sugarcane harvesting process. leaf. Therefore, when the whole stalk sugarcane harvester strips leaves, many sugarcane leaves peeled off by the leaf stripping wheel cannot be discharged from the leaf stripping device, and the sugarcane harvested by the harvester has a high impurity content, which is difficult to meet the requirement of less than 5% impurity content in sugar factories. .

At the same time, the stripping wheel group is the core part of the leaf stripping machine. The greater the speed of the stripping wheel, the greater the striking force, and the cleaner the leaves will be stripped. The leaf-stripping brush on the impeller is also easily damaged, and the life-span of the leaf-stripping brush is also relatively short.
