The Design And Research Of Anti-overturning Banana Picking Machine

Bananas are currently one of the highest-growing fruits in the world,ranking second in the world.China is currently the largest banana producer in the world.Banana output and demand continue to increase.The banana industry has maintained a rapid development trend in recent years.However,the development of China's banana industry still faces many obstacles.The banana picking time in China is relatively concentrated,and the banana picking operation is seasonal and labor-intensive.Due to the problems of dense population and tight farmland in our country,banana picking is still dominated by manual picking.Banana picking has a low degree of mechanization and low picking efficiency.At the same time,China's rural population has a serious aging problem,and the labor force is gradually moving to urban or other Industry shifts,which directly lead to rising picking costs.In order to ensure the sustainable development of China's banana industry,it is extremely important to develop a banana picking machine.This article is aimed at the problems in the current banana picking process in China.Firstly,the composite material elastic mechanics test method is used for the banana fruit handle,and the radial and axial compression test and the moisture content test are performed on the fruithandle sample to obtain all the elastic parameters of the banana fruit handle,and for the subsequent clamping of the cutting component Meta-simulation and machine dynamic simulation provide the basis.Secondly,combine the test results and literature summary to design the banana picking machine and key components.The banana picking machine includes a clamping and cutting device,a picking telescopic arm and a walking mechanism.Focus on the design of clamping and cutting mechanism and banana picking telescopic arm.Innovatively introduced the picking method of the combination of the front support hydraulic telescopic arm and the counterweight,which effectively improved the picking efficiency and stability.At the same time,the strength and stiffness check formulas of the telescopic arm of the banana picker are derived and calculated.Thirdly,the moment method was used to analyze the stability of the four picking conditions of the banana picking machine.The results show that the banana picking machine designed this time will not overturn when working at a horizontal or 30 ° slope.No overturning occurs when driving on a 30 ° slope.The design of the banana picker fully meets the picking conditions.Then,in order to verify the rationality of the structural design under real working conditions,the main components of the banana picker were simulated and analyzed using ANSYS Workbench simulation analysissoftware.The static simulation analysis and modal analysis of the telescopic boom and clamping and cutting parts verified the rationality of the core component design.At the same time,on the basis of satisfying the design,the ANSYS Workbench software optimization analysis module was used to optimize the weight reduction of the telescopic boom and the bottom base.On the basis of satisfying the strength,these components are optimized for weight reduction.Finally,in order to provide a basis for the later optimization of the banana picker,Adams software was used to perform dynamic simulation analysis on the rigid-flexible coupling system model of the banana picker-fruit handle.The dynamic simulation analyzes the influence of the acceleration of the telescopic arm,the quality of the banana fruit and the length of the fruit stalk on the vibration of the banana fruit,and the graphs obtained from the simulation analyze the factors affecting the vibration of the banana fruit.
