摘要
在对目前玉米播种机排种监测方法的研究基础上,设计了一套新的玉米播种机排种监测的试验方法:将4对光电传感器并排安装在导种管内壁以监测空或堵的情况并进行报警;同时,利用安装在排种盘的中心轴上的空心转速编码器,测出排种盘转速连同试验所得的空穴率,从而得出玉米排种量。试验结果表明:该方案模拟实际空或堵的报警率达100%,排种量检测平均精度98.37%,各项性能指标均达到了实际要求。
Based on the research of the current seed monitoring methods of corn planter , a new test method for seed mo-nitoring of corn planter is designed in this paper .Four pairs of photoelectric sensors mounted side by side on the inner wall of the guide tube to monitor the empty or blocked situation and then alarm , moreover , hollow speed encoder mounted on the central axis of the seed plate is used to measure the rotation speed of seed plate , together with empty hole rate ob-tained by a test to calculate the amount of corn seed .Finally , the test results show that alarm rate in simulating the actual empty or blocked situation is 100%in this scheme , accuracy of seeding amount detection on average is to 98 .37%, and all properties and indexes have met the expected standards .
