中文摘要:为了获得胡萝卜缨果拉拽式分离装置最优设计参数,以获取最佳分离效果,建立了拉拽式缨果分离装置运动学模型,定性分析了相关参数对拉拽杆运动学特性的影响。设计了胡萝卜缨果拉拽式分离试验台并进行了缨果分离正交试验,经分析发现拉拽杆的转速对胡萝卜缨果分离效果影响最大,拉拽杆与输送带的夹角对胡萝卜缨果分离效果的影响显著;同时得到了胡萝卜缨果分离装置的最佳参数组合:拉拽杆转速为200r/min、输送带线速度为1.2m/s、拉拽杆与输送带夹角为40°,此时缨果分离的一致性为97%,成功率为94%,损伤率为7.7%。

Abstract:Separating carrot tassel from fruit by pulling can meet the requirement of tassel fruit separation better. In order to provide design parameters for pull type carrot tassel fruit separation device, and obtain the best separation effect, the influence of related parameters on the pull rod kinematics characteristics should be analyzed qualitatively. To analyze the influence of relevant parameters on the kinematic characteristics of pull rod accurately, the kinematics model of pulling device type tassel fruit separation should be established. To verify the correctness of the previous theoretical analysis, the pull type carrot tassel fruit separation test device was designed. Then a series of orthogonal tests were carried out to explore the factors that affecting the effect of tassel fruit separation. In the orthogonal testing, the pull rod speed, belt line speed and the angle between pull rod and conveyer belt were test factors. The comparison between the results of test and theoretical analysis showed that the pull rod speed had the biggest influence on carrot tassel fruit separation effect, and angle between pull rod and conveyer belt also had significant effects on carrot tassel fruit separation effect. At the same time, the best combination of parameters in carrot tassel fruit separating device was obtained as follows: pull rod speed was 200r/min, belt line speed was 1.2m/s, and angle between pull rod and conveyer belt was 40°. The results showed that the concordance rate in the tassel fruit separation was 97%, the success rate was 94%, and the injury rate was 7.7%.

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.
