A fishing device for jumping-out prevention raw shrimp detection

Abstract

The invention discloses a fishing device for preventing jumping out of raw shrimp, which comprises a raw shrimp tank, a first spring, a guide wheel, a crank handle and a fishing net. A movable plate is movable above the raw shrimp tank, and the connecting One end of the plate is fixed with a first spring, the inner side of the connecting plate is fixed with a fixed shaft, the guide wheel is sleeved on the outer side of the fixed shaft, the upper end of the movable plate is fixed with a joystick, and the winding rod Both ends are connected with limiting plates, one end of a traction rope is wound around the outside of the winding rod, a fishing net is provided on the underside of the fishing frame, a fixing rod is provided on the upper side of the fishing frame, and the fishing frame The other side is movably equipped with a fixed plate. The anti-jumping-out raw shrimp detection fishing device can realize the fishing of raw shrimps in containers of different specifications through the same device, which can ensure the accuracy of fishing, and can avoid the phenomenon of raw shrimps jumping out after fishing, thereby improving the The convenience of harvesting raw shrimp before testing.

Description

technical field [0001] The invention relates to the technical field of raw shrimp detection, in particular to a jump-out prevention fishing device for raw shrimp detection. Background technique [0002] After the harvest of raw shrimp, even if it meets the requirements of aquatic product salvage, it is necessary to sample and test the raw shrimp after being collected in the raw shrimp batch storage container. 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. At the same time of fishing, because the activity of raw shrimp is good, it is necessary to sample on the basis of not affecting its activity as much as possible. However, the existing raw shrimp detection There are still the following shortcomings in the actual use of the fishing device: [0003] 1. Most of the existing raw shrimp fishing is carried out with fishing nets, and the size of ...

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
