链板式长短V槽对虾开背去头一体机的设计与试验

Design and experiment on automatic chain head-cutting and back-opening machine for shrimp with V groove

研制一种可在同一工位进行对虾开背去头加工的对虾开背去头一体机,采用长短V槽同步运动进行对虾输送,利用长短V槽相对运动产生的剪切力及去头刀对虾体的划伤进行去头,同时利用开背机构及压紧机构的组合实现对虾开背加工的加工工艺。试验表明,设计的对虾开背去头一体机能够实现对虾的开背及去头工作同时进行,结构紧凑、运行可靠,加工效果好,处理能力远远高于人工,具有推广价值。

An automatic head-cutting and back-opening machine was designed which could open shrimp＇s back and move the head at the same station. The machine used the synchronous movement of the long and the short V groove for shrimp transmission, the shear force produced by the relative motion of the V groove and the scratch by the knife for head removing, and the combination of the back opening institution and compaction mechanism for shrimp＇s back opening. The results showed that, the machine could realize the synchroniza- tion of head-cutting and back-opening for shrimp. The machine has compact structure, reliable operation and good processing quality, and higher processing capacity than artificial. The machine has a high popularization value.
