项目摘要

(1) Study on Planting system for Capsule by RobotThe basic experiment of planting system on capsule seeds using a small robot carried on for useful in planning factory. In this time, Jelly balls as imitation seeds of capsule seeds were used. The elements of a performance for picking seeds were resulted as follows ; a rubber model of a half spherical surface on a nozzle type, a slide system on nozzle holder type, a funnnel shaped on hopper shape and vibration type on a hopper.(2) Development Reseach of Precision Planter by Using computer controlled TechnologyThe goal of this reseach was to establish a new precision planting methodology for realizing the mechanization of planting operations in agricultural and biological production and to response the marketing needs of agricultural products in quality, ruality and high production efficiency.In The research, we developed and tested a precision planter system using computer control and electronic technique for mulching cultivation in agri … More cultural and biological productions. The planter system mounted on a tractor could perform multi-purpose operations including soil tilling, seed bed preparing, plastic mulch film laying, seed planting and seed pressing etc., automatically. The key point of the system is the two row precision planting mechanisms, which consisting of a micro computer, four optical fiber sensors and control actuators of a solenoid controlled shutter opening mechanism and a stepping motor driven a seed metering device. The planting mechanism could plant a seed into the center of a plastic film through the detections of film hole position and seed metering existence on the shutter according to the different planting speed. The planting timing of the shutter opening mechanism were analyzed and tested through theoretical and graphical analysis by computer programs and video camera motion analyzer. The results of indoor preliminary tests shown a satisfied characteristics with the sufficient accuracy of a seed into the center of a film hole with a variety of planting speeds. The gravity point positions in a film hole of a seed planted by the system just were within the area error +-5 mm of the hole center when the hole diameter was 40 mm. Less

(1)胶囊种子机器人播种系统的研究为适应工厂的需要，利用小型机器人进行了胶囊种子播种系统的基础性试验。在这一次，果冻球作为模拟种子的胶囊种子。通过试验，得出了吸嘴式橡胶半球模型、吸嘴保持器式滑动系统、漏斗式漏斗和振动式漏斗四种吸种性能的基本要素。(2)基于计算机控制技术的精密播种机的开发研究本研究的目的是建立一种新的精密播种方法，以实现农业和生物生产中种植作业的机械化，满足市场对农产品质量、产量和生产效率的需求。本文介绍了一种应用计算机控制和电子技术的精密播种机系统， ...更多信息文化和生物产品。该播种机系统安装在拖拉机上，可实现翻耕、整地、铺膜、播种、压种等多功能作业，的自动该系统的核心是由微型计算机、四个光纤传感器、电磁阀控制的百叶窗开启机构和步进电机驱动的排种器组成的两行精密播种机构。播种机构根据播种速度的不同，通过检测快门上的膜孔位置和排种器的存在，将种子播种到塑料薄膜的中心。利用计算机程序和摄像机运动分析仪，通过理论分析和图形分析，对快门开启机构的插种时机进行了分析和试验。室内初步试验结果表明，在不同的播种速度下，种子都能准确地进入膜孔中心，具有良好的特性。当孔径为40 mm时，该系统播种的种子在膜孔中的重心位置正好在孔中心的面积误差± 5 mm范围内。
