摘  要：
在分析现代工厂化育苗技术的基础上,提出并设计了智能化设施育苗机。整机采用PLC技术、传感器技术、异步电动机变频调速等控制技术,能够实现精量播种作业。以白菜种子为试验对象,选取吸孔直径、真空度、种箱移动速度作为试验因素,进行吸种性能的正交试验,经试验得出最优因素参数组合为真空度7 k Pa、吸孔直径0.8 mm、种箱移动速度0.03 m/s,最优因素参数组合下单粒率93.82%、空穴率3.71%、重播率2.47%;在吸种性能最优因素参数组合下,对不同的播种效率做进一步播种性能试验,当播种效率为400盘/h,单粒率达到92.63%,可以满足蔬菜精量播种农艺要求。

摘  要：
An intelligent facilities seedling machine was put forward and designed with the analysis of modern factory seedling technology. PLC programmable control was adopted in this machine. Human machine interface,sensor technology and frequency control of asynchronous motors were integrated into the control system to realize the accurate seeding operation. Selecting suction hole diameter,vacuum degree,seed box moving speed as experiment factors,an orthogonal experiment on suction performance was carried out with cabbage seeds as test object. The experiment result showed that the optimal parameter combination of factors were vacuum pressure of 7 k Pa,suction hole diameter of 0. 8 mm,seed box moving speed of 0. 03 m / s,and under the optimal parameter combination of factors,the singleseeding rate was 93. 82%,miss-seeding rate was 3. 71%,and reseeding rate was 2. 47%. Furthermore,under the above conditions,a seeding performance test was carried out. The test showed that the singleseeding rate can reach 92. 63% with seeding efficiency of 400 tray per hour,which can meet the requirements of precision seeding agronomic for vegetables.
