中文摘要:针对杂粮含水率检测设备不配套和无法快速准确测定多种杂粮含水率的问题,参考国际干燥箱法测定标准,基于TRIZ理论创新设计了一种自主转送式杂粮含水率快速检测装置,实现物料盘在圆柱凸轮轨道上有序可靠的运行,并完成多工位转送机构、自动称量系统和闪烘机构等关键部件的仿真设计与装配验证。应用PLC耦合自主控制技术,实现定量入料、闪烘测量和快速除料3种工序切换,通过精准模块化运算,实时获得准确的杂粮含水率。采用二次正交旋转组合设计的方法,构建表征杂粮含水率检测精度和检测行程时间的协同评价定量模型,优化了闪烘温度、物料粒度和物料质量的参数组合,提升了该装置的运行效能与检测精准性。研究表明,该含水率检测仪的重复性和再现性可靠,检测相对偏差在0.2%以内,测量准确,自动化程度高,可为多样性杂粮含水率快速测定仪的广泛应用提供技术支持。

Abstract:Aiming at the problem of grain moisture detection equipment not matching and the inability to quickly and accurately determine the moisture content of various coarse cereals. According to international standard for oven method, combined with the theory of grain weightlessness, the transferring multistage type quick measuring moisture content equipment was designed by using TRIZ innovative design method, which realized orderly and reliable operation of loading disc on cylindrical cam track. The simulation design and assembly verification of key components such as multi-station transfer mechanism, automatic weighing system and flash drying mechanism were completed. The PLC coupling control technology was applied to realize the cyclic switching of three working positions: quantitative feeding, flash drying measurement and rapid material removal. Accurate moisture value of grain can be obtained in real time by precise modular operation. The quadratic orthogonal rotational combination design method was used to construct a quantitative model for synergistic evaluation of moisture detection accuracy and detection time of miscellaneous grains. The parameters combination of flash drying temperature, grain size and detection quantity was optimized, and the operation efficiency and detection accuracy of the device were improved. The results showed that the device had good performance, high degree of automation, simple structure and operation, the measurement accuracy, repeatability and reproducibility of the measurement system were reliable, and the relative deviation of detection was less than 0.2%, which provided technical support for the wide application of the rapid moisture meter for the variety of coarse cereals.

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.
