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.
