中文摘要:油茶果机械化采摘是目前亟待解决的难题,其中花苞损伤又成为机械采摘难以克服的问题。设计了一种电动胶辊旋转式油茶果采摘执行器,分析了胶辊机构采摘油茶果的过程和原理,得到了油茶果碰撞脱落的临界条件。通过对采摘头回转架组件参数设计,确定了回转架组件上对辊间距有效调节范围为20~65mm,初步拟定回转架转速范围为20~40r/min。在江西农业大学油茶林进行了油茶果采摘试验,并对电动胶辊旋转式油茶果采摘执行器作业中油茶花苞损伤进行了研究。结果表明:当胶辊直径为30mm,间距为25mm,胶辊旋转速度为30r/min,胶辊线速度为0.833m/s时,直径大于25mm的油茶果能全部被采摘,漏采率为13.6%,且未开的花苞未见明显损伤。

Abstract:It is a dilemma to solve the picking mechanization of camellia fruit in the camellia industry, of which camellia bud damage is a bottleneck. A motor driven picking actuator of camellia fruit with rotate rubber roller was developed. The principle of camellia fruit picking by rotate rubber roller was analyzed. The interaction between camellia fruit and rotate rubber roller can be summarized as contact, impact and abscission during the process of camellia fruit picking by rotate rubber roller, through which corresponding forces were derived and the critical condition of camellia fruit’s falling off was obtained. By analyzing the parameters of swinging strut of picking head, the efficient adjustable range between upper and lower rubber roller of swinging strut was designed as from 20mm to 65mm, and the preliminary rotate speed was proposed from 20r/min to 40r/min. Tests of camellia fruit picking and its bud damaging were conducted in the camellia forest of Jiangxi Agricultural University when the prototype was completed. Experimental results showed that as the diameter of rubber roller was 30mm, the rotate speed was 30r/min, the linear velocity was 0.833m/s, and the gap between up and down of rubber roller was 25mm, the diameter of camellia fruit above 25mm can be harvested by rotate rubber roller, the percentage of residual camellia fruits on the camellia branches was 13.6%. What’s more, the damage of unopened camellia bud was bare, which verified the practicability of this prototype and provided the reference for the development of camellia fruit picking machine.

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.
