Elastic Dentation Roller Type Sugarcane Leaf-stripping Device
摘要
Abstract
In order to solve the problem of high impurity rate and stalk broken rate existing in the leaf-stripping process of the whole stalk sugarcane combine harvester, the elastic dentation roller type leaf-stripping test device was designed. The main structure of feeding roller, output roller and leaf-stripping roller and the principle of leaf-stripping were introduced. The structure parameters of main parts were determined. The orthogonal experiments were conducted to study the influence between the following four factors, the installation angle of leaf-stripping component, the center distance between the top and bottom leaf-stripping rollers, rotate speed of leaf-stripping rollers and rotate speed of feeding and output rollers, and the following three indexes on leaf-stripping quality, impurity rate, stalk broken rate and top broken rate. The result showed that the optimal parameters were as following: the installation angle of leaf-stripping component was 90° the center distance between the top and bottom leaf-stripping rollers was 310 mm, rotate speed of leaf-stripping rollers equaled 700 r/min and rotate speed of feeding and output rollers equaled 150 r/min. In the meantime, when the total weight of 319. 19 kg sugarcane was fed continuously into the device in the way of single stalk, the impurity rate, stalk broken rate and top broken rate reached to 1. 56% , 20. 45% and 65. 97% . Otherwise, when the total weight of 274. 52 kg sugarcane was fed continuously into the device in the way of three to five stalks simultaneously, the final result was 2. 38% , 25. 93% and 75. 59% respectively.关键词
