摘　　要：为了解决对虾在机械自动化剥壳过程中定向难的问题，作者设计了一种对虾头尾与背腹定向装置。根据对虾的体型特征，分别利用倾斜布置的V型滑槽和曲型面滑道实现对虾的头尾定向和背腹定向，并进行了原理分析。针对分级后长度为110～130mm的新鲜南美白对虾进行了试验研究，结果表明利用V型槽进行对虾头尾定向的成功率达到了99．4％，利用曲型面滑道进行对虾背腹定向成功率达到了89％，定向装置原理合理，方法可行。研究结果可为对虾机械自动化剥壳加工中定向连续喂料设备的产品开发提供技术依据。In order to solve the difficulty of directional transport in the automatic peeling process of shrimps, a directional transport device of Penaeus vannarnei was designed. Based on the physical characteristics of shrimps, a mechanism was dopted in which the tilt arrange- ment of type V groove was used to set the shrimps~ heads forward,and the tilt arrangement of slideway with curved surface was used for setting the shrimps＇ back inside. The theory and principles of the mechanism were also analyized. The shrimp with a body length between 110 mm to 130 mm after a strict grading were taken as the research object and the experiment of directional transport was carried out. The experimental results showed that the measured av- erage success rate of heads forward setting of the shrimp was 99.4% by using the V groove, and the success rate of backs inside setting was 89 % by using the curved surface slide. There-fore, the orientation principles of the mechanism are reasonable, and the method is feasible. The results could provide technical references for the design of feeding machines which can be used in continuous processing of shrimps.
