中文摘要:针对我国现有马铃薯分级机普遍存在的分级等级少、分级效率差等问题,设计了一种新型辊式马铃薯分级机。对该机器的工作原理进行了阐述。通过理论计算对其关键部件进行设计,确定了分选装置的结构参数;对马铃薯运动过程进行分析,确定出影响马铃薯分级机分级效率和分级精度的因素,利用ADAMS仿真软件对马铃薯分级机分级性能进行仿真试验,得出马铃薯运动位移曲线,与结构理论相吻合。以马铃薯的上料量、辊子转速、提升装置的提升角为试验因素,以马铃薯分级机的分级精度和分级效率为试验指标进行样机试验,试验结果表明:马铃薯的上料量为55t/h、辊子转速为120r/min、提升角为24°时,其分级精度为96%,分级效率为53.7t/h,满足马铃薯分级机的作业要求。

Abstract:With the implementation of the “Thirteenth Five Year” development plan of potato processing industry and the promotion of “main food” strategy of potato, the planting area of Chinese potato is getting larger and larger;the shape difference of potato or seed potato before potato planting is different for potato production. It has important influences, and it needs to be accurately screened by grading equipment to classify seed potatoes and potatoes of similar size for the same number of cuts;and quality grading of potatoes is also a necessary step before processing exports. However, most of the potato grading methods in China use traditional manual grading, which not only has high labor intensity, but also has low work efficiency. At present, potato grading machinery in China mostly uses the general equipment of fruit and vegetable products, and the grading equipment for potato is less, which can not meet demand for potato processing and export in China. Aiming at the problems of low grades and poor classification efficiency of the existing potato grading machines in China, a new roller potato grading machine was designed. The working principle of the machine was explained. The key components were designed by theoretical calculation, and the structural parameters of the grading device were determined. The force analysis of the potato movement process was carried out to determine the factors affecting the classification efficiency and classification accuracy of the potato grading machine. The potato grading machine was analyzed by Adams simulation software. The performance was simulated and the displacement curve of the potato was obtained, which was consistent with the structural theory. Taking the feeding amount of potato, the rotation speed of the roller and the lifting angle of the lifting device as the test factors, the bench test was carried out with the classification accuracy and classification efficiency of potato classifier. The test results showed that the potato feeding amount was 55t/h. When the roller advance speed was 120r/min and the lifting angle was 24°, the classification accuracy was 96%, and the extension efficiency was 53.7t/h, which met the operation requirements of potato grading machine. It provided a good foundation for the design and optimization of potato grading devices.

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.
