Anti-jumping-out fishing device for raw shrimp detection

Abstract

The invention discloses an anti-jumping-out fishing device for raw shrimp detection. The anti-jumping-out fishing device comprises a raw shrimp tank, a first spring, a guide wheel, a crank and a fishing net; a movable plate is movably arranged above the raw shrimp tank, the first spring is fixed at one end of a connecting plate, a fixed shaft is fixed at the inner side of the connecting plate, and the guide wheel sleeves the outer side of the fixed shaft; and an operating rod is fixed to the upper end face of the movable plate, limiting plates are connected to the two ends of a winding rod, one end of a traction rope is wound around the outer side of the winding rod, the fishing net is arranged at the lower side of a fishing frame, a fixing rod is arranged at the upper side of the fishing frame, and a fixing plate is movably installed at the other side of the fishing frame. According to the anti-jumping-out fishing device for raw shrimp detection, raw shrimps in containers of different specifications can be caught through the same device, the catching accuracy can be guaranteed, the phenomenon that the caught raw shrimps jump out can be avoided, and then the catching convenience before raw shrimp detection is improved.

Description

technical field [0001] The invention relates to the technical field of raw shrimp detection, in particular to a jump-proof fishing device for raw shrimp detection. Background technique [0002] After the raw shrimp is caught, even if it meets the requirements for salvage of aquatic products, it is still necessary to sample and test the raw shrimp after being collected into the bulk storage container of raw shrimp. Because raw shrimp is different from other aquatic products, it has strong aggressiveness and It is more flexible, so when sampling, it is necessary to use a specific fishing device. While fishing, because the activity of raw shrimp is better, it is necessary to sample on the basis of not affecting its activity as much as possible. However, the existing raw shrimp detection The fishing device still has the following disadvantages in actual use: [0003] 1. Most of the current fishing for raw shrimp is carried out by fishing nets, and the size of the net opening is...

Problems solved by technology

[0006] The object of the present invention is to provide a fishing device for detecting raw shrimp that prevents jumping out, so as to solve the above-mentioned background technology. It is proposed that raw shrimp can easily jump out of the fishing net after fishing, and repeated fishing is required. Therefore, the same fishing device can be used for different specifications. The problem that the raw shrimp fishing in the container is not convenient enough
