木薯收获机挖掘铲挖深控制系统设计
Design of Automatic Depth-control System for Digging Blade of Cassava Harvester
摘要
Abstract
During the process of harvesting cassava,the digging blade with a certain earth entry angle shows a tendency towards the deeper direction of earth when it's working ,which bring about the problems that machine power consumption is too large.Besides,different lug angles are needed when digging blade is cutting and breaking soil.To deal with the two issues, we have developed a parallel four-bar mechanism, which makes the shovel satisfy a certain trajectory.In order to realize the precise depth-control function of digging blade, we developed the farmland detection device, using sensors to measure signal in the digging process and the signal outputs to the control system.After processing of calculation, the received signal makes electromagnetic directional valve switch which enable the hydraulic cylinder action, so as to realize the automatic control of digging depth.关键词
