| At present,the acquisition of camphor leaves in the Yibin area of Sichuan Province mainly relies on manual collection,which has high labor intensity,low work efficiency,and insufficient production capacity.Currently,there are few reports on equipment that integrates leaf picking and collection that is suitable for outdoor mountainous conditions.In response to this situation,this article has developed a vehicle mounted camphor leaf collecting machine that can achieve mechanized cutting and collection of camphor leaves,improve production capacity to meet production requirements.Firstly,the operating conditions range of the equipment was determined based on the outdoor mountainous conditions,and on this basis,in-depth process analysis was conducted to determine the operating process flow;A functional analysis was conducted to determine the main functions of the device,and a human-machine integrated operation method was adopted to propose a device principle scheme that integrates vehicle mounted,leaf picking,and leaf collection.This plan has the function of efficiently picking and collecting leaves from camphor trees at a height of 4-6 meters by climbing and crossing obstacles in outdoor mountainous conditions.Secondly,based on the above scheme and technical parameter requirements,structural designs were carried out for each functional component,including the walking mechanism,leaf cutting mechanism,robotic arm structure,leaf collection mechanism,etc.,and the prototype design was ultimately completed.Among them,the cutting tools that currently meet the requirements of this operation are all of a linear structure,and the efficiency of picking the curved contour of camphor tree crowns is very low.To improve the picking efficiency,a curved cutting tool scheme has been proposed,and its structural design and parameter optimization have been carried out.Finally,considering that the entire machine has a cantilever and slender rod series structure,which has poor vibration resistance,the vibration characteristics of the entire machine were studied.To avoid resonance of the equipment,modal analysis was conducted on the entire machine to verify that its inherent vibration characteristics meet the requirements;To avoid excessive vibration of the equipment,transient dynamic analysis was conducted on the entire machine,and the maximum amplitude of the machine during stable operation was determined,verifying that this indicator meets the requirements of the international vibration standard(ISO10186). |
