China is a large country of sugar cane plantations, the planting area of more than2000mu,it is one of the main crops in some provinces of southern China. Sugarcanehas a high economic value, the formation of the output value of hundreds of billionseach year. In addition, with the advent of comprehensive mechanization of agriculture,our country continued to increase support for agriculture, the main crops,like wheat,corn, rice harvest, has been largely mechanized harvesting. As one of the main cropsin the south,we still rely entirely on traditional manual harvest that is inefficiencyand high cost. The sugarcane leaf separation device is the core work part for small-scale sugarcane harvester, has been an important factor affecting sugar cane harvesterefficiency. In this paper, sugarcane leaf separation device for sugarcane harvester asthe research object, combination designed to theory and practice, we devise a kind ofsugarcane leaf separation device to meet the performance requirements on small-scalesugar cane harvester.In this paper, we research subject from sugarcane leaf separation device structuredesign, simulation analysis and test optimization three aspects. First, we have a surveyof cultivation for sugarcane and determine that the use of small sugarcane harvester isfit for our country’s sugarcane harvest due to the complex terrain of China’s sugar canegrowing region. The sugarcane leaf separation device for harvester components: thefeed device, stripping leaf device, the leaf institutions and output mechanism. How thevarious devices work is described. The device’s drive system uses hydraulic drivesystem as a dynamic system, which is compact, economical and practical, easy tomaintain. Secondly, the feeding device virtual prototype institutions and mathematicalmodel of sugarcane leaf separation device are built, and have a virtual simulation.Through the analysis of the simulation data to verify the rationality of the design of thedevice, and provides important data to support field trials of the device. Finally, the use of orthogonal experiment method harvesting pilot program designed to matchspeed for all institutions of the sugarcane leaf separation device. The design of theprogram can get comprehensive test information using only a small number of testdata, scientific and rational use test methods to reduce the workload of physicalprototypes in field trials. Range analysis of orthogonal test data results, the method candetermine the role of various factors significant to find the optimal speed matchingscheme. And a summary of the existing problems in the harvest during the test,provides an important reference for the structural improvement of the device.
