中文摘要:在弹齿滚筒式捡拾器试验台上,以紫花苜蓿为捡拾对象,滚筒转速、机器前进速度和牧草含水率为试验因素,功率消耗与捡拾损失率作为性能检测指标,进行了正交试验和弹齿端部加速度试验,旨在探索弹齿滚筒式捡拾器的工作参数、结构参数与牧草收获条件对捡拾性能的影响。试验结果表明:凸轮廓线对捡拾器工作性能有较大影响;滚筒转速和牧草含水率均对捡拾器工作性能影响极显著,机器前进速度对工作性能影响显著;捡拾器工作性能的影响因素主次顺序为滚筒转速、牧草含水率、机器前进速度,最佳性能参数组合为滚筒转速42r/min、机器前进速度4.0km/h、牧草含水率15.1%。弹齿端部加速度频谱分析表明:在滚筒转速、机器前进速度保持一定的情况下,随着牧草含水率的增加,弹齿端部加速度呈上升趋势,捡拾器功率消耗增加,捡拾效率下降。

Abstract:Cylinder rotational speed and forward speed are two main working parameters of spring-finger cylinder pickup collector. Harvesting, different ways of storage and transportation also have forage moisture content requirements. Through researching the influence law of forage moisture content and working parameters on the pickup collector collecting performance, the pickup performance index of optimal parameter combination can be got, and it can be used to guide the actual production and provide technical support and theoretical basis for pickup collector design and manufacturing. For collecting alfalfa, taking cylinder rotational speed, machine forward speed and forage moisture content as test factors, taking power consumption and leakage rate of picking up as performance index, orthogonal experiments were done on the original device of spring-finger pickup cylinder collector and the improved convex contour line device at the same time. Through the orthogonal experiment and the spring finger end of acceleration experiment, effects of the three factors on collecting performance were analyzed. Levels of orthogonal test factors were selected from single factor experiment results, namely the machine forward speed of 3.5km/h, 4.0km/h and 5.0km/h, cylinder rotational speed of 42r/min, 50r/min and 60r/min, forage moisture content of 15.1%, 17.3% and 22.3%. The test results showed that the CAM track had greater influence on collecting performance, the cylinder rotational speed and forage moisture content had extremely significant effects on working performance, the machine forward speed had influence on working performance. The affecting sequence of importance for three factors on power consumption and leakage collecting rate were cylinder rotational speed, forage moisture content and machine forward speed. When cylinder rotational speed was 42r/min, forage moisture content was 15.1%,and machine forward speed was 4.0km/h, the collecting performance of the pickup collector was the best.Through the spectrum analysis, it was concluded that the spring-finger end acceleration was increased with the increase of forage moisture content, power consumption was increased and pickup leakage rate was declined with the increase of forage moisture content. It would lay research foundation for the spring-finger pickup cylinder collector to match the optimal working parameters and structure parameters and collecting performance for the future.

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.
