A floating defoliating roller for sugarcane harvester

Abstract

The invention discloses a floating type leaf-stripping roller for a sugar cane harvester. The floating type leaf-stripping roller comprises a power input shaft, a roller rack, a leaf-stripping plate, clamping plates, a limit spring and the like. Six rib plates are radially welded to the roller rack. A plurality of mounting holes and spring limit holes are evenly distributed in each rib plate. The longitudinal section of the leaf-stripping plate is of an inverted-T shape, the upper portion of the leaf-stripping plate is evenly provided with V-shaped grooves, and a plurality of protruding teeth are machined in each V-shaped groove. The L-shaped clamping plates are provided with a plurality of mounting holes corresponding to the rib plates. The leaf-stripping plate is elastically connected with the rib plates through a plurality of limit springs mounted in the spring limit holes. The clamping plates are mounted on two sides of the rib plates of the roller rack through bolts and clamp the leaf-stripping plate. The floating type leaf-stripping roller has the advantages that the adaptability of the leaf-stripping roller to sugar canes of various diameters can be improved effectively, the contact area of the V-shaped grooves and the sugar canes is increased, flexible contact of the sugar canes and the leaf-stripping roller is guaranteed, sugar cane blocking and breaking probability is lowered, and stripping efficiency is increased.

Description

technical field [0001] The invention relates to agricultural machinery technology, in particular to a leaf stripping mechanism used in mechanized harvesting of sugarcane. Background technique [0002] According to the statistics of the United Nations Food and Agriculture Organization database, as of 2014, my country's sugarcane planting area reached 1.75 million hectares, ranking third in the world after Brazil and India. As one of the main economic crops in southern my country, sugarcane is widely planted in Guangxi, Yunnan, Guangdong and Hainan. With the continuous development of modern agricultural technology, the advantages of time-saving, high-efficiency, low-cost and low-labor intensity of sugarcane mechanized harvesting continue to be highlighted. Problems such as high impurity content and serious damage to sugarcane have seriously reduced the income of sugarcane farmers and the quality of sugar squeezed by sugar factories. Harvester operating performance is one of ...

AI Technical Summary

Problems solved by technology

When the diameter of the sugarcane fed is small, the leaf stripping element on the stripping roller has a small brushing force on the sugarcane, and it is difficult to peel off the sugarcane leaves; when the diameter of the sugarcane fed is large or the degree of curvature is high , and it is easy to cause the blockage of the conveying channel, which will lead to the breakage of the sugarcane or the damage of the epidermis, and in severe cases, the shutdown of the harvester
