Ridge As A Sugarcane Light Simplified Hand-held Sugarcane Harvester

In recent years,the number of people engaged in sugarcane cultivation and production in Yiwu City has been increasing.Sugarcane is not only the main cash crop for local farmers,but also as a raw material for making brown sugar,it also has a profound impact on the development of the local brown sugar industry.Since Yiwu belongs to the hilly area,the sugarcane planting areas are distributed in a stepped manner,and the planting mode is mainly scattered by a single farmer.It is difficult for medium and large sugarcane harvesters to be popularized locally.Therefore,it is of great significance to develop a miniature sugarcane harvester that is suitable for operation in hilly areas and is economical to promote the development of Yiwu brown sugar industry and the mechanized production of local sugarcane.In order to realize the goal of cutting the sugarcane and transporting it to the side of the field ridge and laying it in an orderly manner,a light and simplified walk-behind sugarcane harvester is designed,and the cutting tool and transmission device are optimized to reduce the Sugarcane head breaking rate,reduce tool wear.The main work of this paper is as follows:1)Measured and counted the appearance size of sugarcane variety code Yuetang54/474,and carried out the mechanical properties test of sugarcane based on the universal material testing machine,and measured and counted the mechanical property parameters of sugarcane skin and inner core;Then,based on the Workbench software,according to the measured mechanical characteristic parameters,the model of sugarcane skin,sugarcane inner core and tool is simplified for dynamic simulation of cutting sugar cane;Then,according to the three factors of working speed,tool reciprocating speed and tool included angle,a three-factor three-level orthogonal simulation experiment was designed with the maximum equivalent stress on the tool during sugarcane cutting as the response value.After analysis,the combination of the three factors was obtained when the equivalent stress was minimum.2)The scheme of the whole machine layout,cutting tool,cane feeding mechanism and directional conveying mechanism of the sugarcane harvester is designed.The whole machine is driven by a walking tractor,and a 186 f diesel engine is selected as the power source,and according to the optimal working parameters obtained from the orthogonal simulation test,the transmission mechanism and cutter structure of the harvester are optimized,so that the working speed of the whole machine,the reciprocating speed of the cutter,and the included angle of the cutter can be close to the optimal parameters during the operation.combination.3)Completed the virtual prototype assembly and development of the light and simplified walk-behind sugarcane harvester,and field experiments were carried out with the sugarcane head breaking rate,sugarcane directional lodging rate and total loss rate as indicators,and it was verified that the optimization results were reasonable and reliable.
