中文摘要:针对目前克氏原螯虾加工去除虾肠主要依靠手工,存在劳动强度大、生产效率低、产品易污染的问题,设计了一种连续夹拉式克氏原螯虾去肠机,将经过去头工序的克氏原螯虾虾尾放在虾尾夹下夹上,随着虾尾夹一起运动,在夹盖导轨和弹簧的作用下使虾尾夹上盖闭合,夹住虾尾运动到去虾肠装置时,去虾肠组件在链条的带动下运动,尾扇沿着尾扇导板进入去肠夹嘴中,去肠夹嘴将尾扇先夹紧,后连同虾肠一起拉出。详细阐述了克氏原螯虾去肠机的关键部件设计,包括去虾肠机构、去虾肠导轨、输送装置、虾尾夹紧自锁、虾肠清扫等,并完成传动系统的设计和样机试制,设计的样机通过调节虾尾夹与去肠夹嘴的相对位置,对不同大小的克氏原螯虾适应性好。通过样机试验测试,其去肠率达91.0%,去净率达86.5%,单组机构生产效率为1.4个/s。

Abstract:At present, Procambarus clarkii processing enterprises mainly remove shrimp intestines manually. The problems of large labor intensity, low production efficiency and easy to pollution were existed. A continuous clamping and pulling intestine removing machine for Procambarus clarkii was designed. After the head removing process, the shrimp tail was put in the clamping device and moved with it at the same time. The upper cover of the shrimp tail was closed with the action of the clip cover guide rail and the spring. When the shrimp tail moved to the intestine removing device, the shrimp sausage component was driven by chains. The tail fan got into the intestine removing clamp mouth along the tail fan guide. The intestine removing clamp mouth first clamped the tail fan, and then pulled it out with the shrimp intestines. The key parts of continuous clamping and pulling intestine removing machine were descripted, including shrimp intestines institutions, shrimp intestines guide rail, conveyer, shrimp tail clamp lock, shrimp intestine cleaning, etc. The transmission system design and prototype test were also accomplished. Though adjusting the relative position of the shrimp tail clamp and intestinal clamp mouth, different sizes of Procambarus clarkii could adapted well. Through the prototype test, the following result could be got as intestine removing rate of 91.0%, net rate of 86.5%, production efficiency of single mechanism of 1.4 shrimp per second.

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.
