【摘要】 针对目前半自动移栽机作业效率低、控制系统性能不稳定等问题,提出一种整排取苗、双接苗带投苗的取投方案,并设计开发了控制系统。工作时,双苗盘每次进给一排,使钵苗到达取苗位,取苗机械手整排取苗后输送到放苗位;机械手放苗,钵苗进入接苗带栅格中,接苗带转动投苗。系统采用PC机作为上位机,由LabVIEW构建控制系统操作界面;PLC作为下位机,接受传感器的检测信号和上位机发送的指令信号,通过控制步进电机和气缸协同工作来完成整排穴盘苗的取投。试验表明:实时操作上位机可以控制系统的运行,监测机械手运动位置和取投苗过程,实现了整排穴盘苗取投过程的监视与控制。更多还原

【Abstract】 Aiming at the problems of low efficiency and unstablecontrol system of semi-automatic transplanter.In this paper, a scheme of whole row seedling and double grafting seedling with seedling was put forward.Design and development control system.The two trays are fed one row at a time to make the potted seedlings reach the seedling picking position.After the whole row of seedlings are collected by the seedling picking manipulator, they are transported to the seedling releasing position, and the seedlings are released by the manipulator.The potted seedling enters into the grid of seedling receiving belt, and the seedling receiving belt rotates to throw seedlings.The system uses PC as the upper computer and LabVIEW as the control system interface.As the lower computer, PLC receives the detection signal of the sensor and the command signal sent by the upper computer.By controlling the step motor and the cylinder to work together, the whole row of cavity tray seedlings can be taken and put into operation.The test shows that the real-time operation of the upper computer can control the operation of the system, monitor the movement position of the manipulator and the process of picking and throwing seedlings.To realize the monitoring and control of the whole row of seedlings.更多还原
