Swimming crab binding machine

The invention discloses a swimming crab binding machine, and belongs to the field of binding devices. The swimming crab binding machine is used for binding swimming crabs during on-site operation of fishing boats. The swimming crab binding machine comprises a frame, a rubber band conveying mechanism and a binding mechanism. A transfer mechanism and the binding mechanism are connected with a power mechanism. The power mechanism is connected with a control device. The transfer mechanism comprises a conveying guide rail which is matched with at least two conveying wheels. The binding mechanism comprises an expanding mechanism. Pushing mechanisms are arranged on two sides of the expanding mechanism which is connected with a transfer guide rail. The control device comprises a sensing device and a control circuit. The sensing device is connected with the control circuit. The control circuit is connected with the power mechanism. Due to the technical scheme, the swimming crab binding machine has the advantages that the swimming crabs can be bound quickly after being fished by the fishing boats and the number of operators for binding the swimming crabs can be reduced, so that labor cost is reduced while binding efficiency of the swimming crabs is improved.
