中文摘要:针对立辊式玉米收获机割台夹持输送装置存在夹持均匀性和稳定性差,故障率高等问题,设计了一种结构简单、输送效果好、可靠性高的间隙定位夹持输送装置。提出了玉米植株间隙定位夹持输送方式,分析了间隙夹持定位输送装置主要结构与运动参数的设计方法;通过正交试验确定了影响夹持输送质量的3个主次因素依次为输送轨道间隙、夹持输送链速度和夹持输送链长度;确定A2B3C3为较优组合,即夹持输送链长度为130cm、输送轨道间隙为3.1cm、夹持输送链速度为4.5m/s;在该条件下喂入姿态成功率为92.5%、断茎率为0.25%,输送过程稳定可靠,不存在堵塞问题,满足立辊式玉米收获机的作业要求。

Abstract:In view of the gripping and conveying device which belongs to the existing vertical corn harvest header with low gripping uniformity, stability and high failure rate, a clearance located gripping and conveying device with simple structure, favorable conveying effect and high reliability was developed. The device solved the stem gesture adjusting, breaking stem and blocking problems in the working process of vertical corn reaper;ensured that the stem would be located, stably conveyed and directionally fed;and improved the reliability of vertical roller corn harvest header. A corn clearance located and conveyed method was proposed and the designation method of the main structure and motion parameter of clearance located gripping and conveying device was analyzed, its main structure and working parameters that influenced the reliability of ordered located conveying were explored and then the relevant design theory was established. A theory reference was provided for design of vertical roller gripping and conveying device. The main parameter influenced the gripping and conveying quality was determined by orthogonal test method which included the clearance of the gripping and conveying track, the velocity of the clearance gripping and conveying chain and the length of the clearance gripping and conveying chain, and the optimal result showed that the best combination was A2B3C3 group that the length of the clearance gripping and conveying chain was 130cm, the clearance of track was 3.1cm, the velocity of the clearance gripping and conveying chain was 4.5m/s. And the corresponding performance indexes were as follows: the success ratio of stem gesture feeding was 92.5%, the ration of break stem was 0.25%, the conveying process was stable and without blocking, which could completely satisfy the requirement of the vertical roller corn reaper. This research can supply the study basis to structure improvement and performance optimizaiton of delivery mechanism for vertical-rollers type of corn harvester.

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.
