中文摘要:为了方便、准确地检测不同种类玉米精量排种器的排种性能参数,设计了一种排种质量自动检测仪。该检测仪由PLC、伺服电动机、光电传感器、触摸屏组成,可以在不同播种参数(如播种粒距、播种速度、排种盘型孔数)下实时检测排种器的合格率、漏播率、重播率、粒距变异系数等播种质量参数,并可以检测指夹式排种器各个指夹的重播数和漏播数,同时对种子的下落情况进行实时的动画模拟;当下种粒数达到设定的下种目标时,系统自动停止检测并将检测到的排种质量参数自动显示和保存。为验证该检测系统的检测精度,分别与JPS—12型检测台和MeterMax型排种器检测仪进行了对比试验,试验结果表明:在4、8、12km/h 3种播种行进速度下,本文检测仪的检测精度与JPS—12型检测台的检测精度相近(检测结果相差不超过2%);在4~12km/h的速度下,本文检测仪的检测精度与MeterMax型排种器检测仪的检测精度也相近(对指夹式排种器的检测结果相差小于2%,对气吸式排种器的检测结果相差小于0.7%)。试验证明该检测仪的检测精度符合使用要求。

Abstract:In order to test the performance of different types of maize precision seed meters accurately and conveniently, an instrument for testing seed meter’s performance was designed. Utilizing PLC as control component, the instrument can achieve driving seed meter by servo motor, detecting falling seeds by photoelectric seed sensor, setting planting parameters and displaying detection results by touch screen. Besides, under different planting parameters (i.e., seed spacing, planting speed, and number of holes on seed plate), it can real-timely test seed meter’s seeding performance indices, such as quality of feed index, miss index, multiple index and precision index. Meanwhile, the instrument can detect the multiple and miss number of each clip in finger pick-up seed meter and make real-time animation simulation to the dropping situation of seeds. When the quantity of dropping seeds met the number set out, the instrument would stop detecting and save the results automatically. To verify the detection precision of the instrument, a comparison experiment with JPS—12 seed meter detection platform and MeterMax seed meter detector was carried out. Experimental results showed that the instrument and JPS—12 seed meter detection platform’s performance were almost the same at three speeds of 4km/h, 8km/h and 12km/h, and the quality of feed index for testing finger pick-up seed meter was differed by less than 2%. The detection precision of the instrument and MeterMax seed meter detector were much the same at nine speeds from 4km/h to 12km/h, because the results for testing finger pick-up seed meter were differed by less than 2% and the results for testing air-suction seed meter were differed by less than 0.7%. As a consequence, the instrument met requirements for testing seed meter’s performance.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
