Design and experiment of adjustable horizontal fruit automatic collection device for loess hilly land
摘要
Abstract
In response to the planting mode of forest fruits in the loess hilly area,this article presents a design for an adjustable horizontal fruit automatic collection device.The device comprises an automatic opening and closing mechanism,connecting components(leveling shaft,telescopic tubes,and electromagnetic bolt)and a single-track chassis.The device is capable of automatically unfolding the collection umbrella during forest fruit collection operations,while simultaneously adjusting its level to mitigate the impact of ground slope on the collection efficacy.A kinematic analysis was conducted on the automatic opening and closing mechanism,and MATLAB was employed to optimize the dimensions of the connecting rod.A kinematic simulation was conducted using ANSYS Workbench,and the results demonstrated that the optimized automatic opening and closing mechanism could effectively drive the opening of the umbrella.Field experiments were conducted using red dates as the subject matter.The test results demonstrate that the qualified rate of umbrella tension is 100%,and that the adjustment range of collecting umbrella pitch angle is from 0° to 20°,which meets the design requirements.When the ground slope is between 0° and 20°,the fruit receiving rate of the collection device is 91.63%after adjusting the pitch angle of the umbrella.This rate remains unaffected by changes in ground slope,demonstrating the device's ability to adapt to forest fruit collection operations in loess hilly areas.关键词
