中文摘要:高速精密播种作业是大豆、玉米等作物播种的主要发展方向之一。该文针对高速精密播种作业中气吸式排种器,设计了排种器吸种状态检测系统(seed disc suction performance detection system, SDSPS),该系统采用凹形光电传感器采集排种盘吸种信息、应用光电旋转编码器采集排种轴转动角度等信息,通过对光电传感器的输出信号和光电编码器脉冲信号进行处理,得到排种盘每个吸孔的吸种情况,从而进一步获取整个排种器的工作状况。与排种器试验台常用的图像处理检测系统(seeding detecting system based on image processing, SDSIP)在6组作业条件下进行了试验台对比试验,并单独进行了检测单个吸孔吸种量可行性试验。试验通过F检验和T检验(α=0.05)得出2种系统测量值总体方差相同和均值一致。精度分析结果表明SDSPS相比于SDSIP的最大相对误差为0.31%,系统稳定性分析结果表明SDSPS与SDSIP的波动幅值比较接近,两者的最大相对偏差值都不超过1%,SDSPS检测单个吸孔吸种量的最大相对误差为16.67%。通过田间试验验证,SDSPS对于漏吸种量和多吸种量,检测系统检测值与实际值相对误差平均值分别为3.87%和8.42%。SDSPS能有效的进行排种盘吸种性能检测,对单个吸孔吸种量的检测也具有较高的可信度,可以为气吸式排种器性能检测与改进提供技术支撑。

Abstract: The air suction type soybean seed-metering device is the core component of the air suction soybean planter. Therefore, the stability and reliability of the machine in working determines the seeding quality of the whole machine. Therefore, high-speed and precision sowing is one of the main development directions of soybeans, corns and other sowing crops. The working state of the seeding machine in the working process is difficult to be directly observed with the naked eye. Once the fault of the metering device occurs, it is very difficult to find and deal with it in time. In?this?paper,?the application of air suction type seed-metering device in high-speed and precision seed metering was discussed, and the seed disc suction performance detection system (SDSPS) was designed. The system used a concave photoelectric sensor to collect the information of seed suction of the platters and used the photoelectric rotary encoder to collect information of the rotation angle of the seed-bearing shaft. By processing the output signal of the photoelectric sensor and the pulse signal of the photoelectric encoder, the seed disc suction performance detection system (SDSPS) can detect every suction holes’ sucking condition, so that the working condition of the whole metering device can be detected. It is of great significance to improve the working performance of air-sucking soybean seed metering device. Bench tests were carried out under six working conditions, and the experimental data were collected. At the same time, the feasibility tests were carried out to detect the absorption of single hole to the seeds. All the test data were collected and compared with the test data of the commonly used system which called Seeding Detecting System based on Image Processing (SDSIP)). Through F-test and t-test (α=0.05), it was found that the total variances of the two systems were the same and the mean values were the same. The results of accuracy analysis showed that the maximum relative error of SDSPS was 0.31% compared with that of SDSIP. The results of system stability analysis showed that the fluctuation amplitude of SDSPS was similar to that of SDSIP, and the maximum relative deviation between SDSPS and SDSIP was less than 1%. The maximum relative error of the SDSPS in the detection of the suction amount of single suction hole was 16.67%. Through the field test,for the effects of SDSPS on the amount of seed lost and the amount of multiple species absorbed, the average relative error of detection value and real value of detection system was 3.87% and 8.42% respectively, and the maximum relative error values were 10.34% and 20.00% respectively. The reason for the error is the complex conditions of the fields, such as the uneven surface environment and so on. The vibration of the machines and tools caused by the rough ground makes the data measured by this method deviate, resulting in abrupt errors. SDSPS can effectively measure the seed absorption performance of seeding suction. There is also a high reliability in the detection of the amount of seed absorbed by a single suction hole. It can provide technical support for the performance detection and improvement of the air suction type seed-metering?device. The test system designed in this paper can effectively detect the working performance of sucking holes in the metering disk. It can also find out the problem of seed suction hole, and provide reference for subsequent improvement and performance improvement of seed tray so as to speed up the research and development of the metering device.
