Auxiliary beach oratosquilla oratoria catching device

Abstract

The invention relates to the technical field of marine product catching, and discloses an auxiliary beach oratosquilla oratoria catching device. The device comprises an inner barrel; a piston is movably installed on the inner wall in an inner barrel cavity; a pressing rod is fixedly installed at the top end of the piston; the top end of the pressing rod extends out of the outer side of the inner barrel through a hollow part in the top of the inner barrel; a pressing ball is arranged on a top plate; and a fixed plate is fixedly installed on the inner wall of an air hole in the top plate. According to the auxiliary beach oratosquilla oratoria catching device, by arranging the inner barrel, the pressing rod, the piston, a bottom barrel and a one-way valve, a beach comber continuously pressesthe top plate in a reciprocating mode, and air in the inner barrel cavity is continuously blown into an oratosquilla oratoria hole, so that seawater in the oratosquilla oratoria hole becomes turbid, and oratosquilla oratoria runs away to the outside of the oratosquilla oratoria hole under instinctive reaction; and the seawater in the oratosquilla oratoria hole becomes turbid through the air, so that the oratosquilla oratoria is choked and runs out, and the oratosquilla oratoria catching efficiency of the beach comber is improved.

Description

technical field [0001] The invention relates to the technical field of seafood catching, in particular to an auxiliary catching device for mantis shrimp on a beach. Background technique [0002] Mantis shrimps are commonly known as Pipi shrimps. When the tide goes down, those who catch the sea will carry bamboo baskets on the diving beach to catch the mantis shrimps. The caves of the mantis shrimps are generally connected to each other. The existing mantis shrimps There are generally two types of capture. The first type is that the mantis shrimps are directly excavated by the sea hunters with a shovel to dig out the mantis shrimps in the caves. However, this situation often causes the mantis shrimps to escape to other caves. Finally, the water quality in this area is turbid, and it is difficult to catch the mantis shrimp, so that the mantis shrimp can escape. Secondly, this kind of situation makes it more time-consuming and laborious for the sea hunters. The mantis shrimp ha...

[0002] Mantis shrimps are commonly known as Pipi shrimps. When the tide goes down, those who catch the sea will carry bamboo baskets on the diving beach to catch the mantis shrimps. The caves of the mantis shrimps are generally connected to each other. The existing mantis shrimps There are generally two types of capture. The first type is that the mantis shrimps are directly excavated by the sea hunters with a shovel to dig out the mantis shrimps in the caves. However, this situation often causes the mantis shrimps to escape to other caves. Finally, the water quality in this area is turbid, and it is difficult to catch the mantis shrimp, so that the mantis shrimp can escape. Secondly, this kind of situation makes it more time-consuming and laborious for the sea hunters. The mantis shrimp has to bend down many times to operate. The second method, Sea hunters use their arms and fists to continuously press the mantis shrimp caves, pressing the seawater in the mantis shrimp caves into a turbid state, and "choking" the mantis shrimps out. In this case, the labor intensity of the sea hunters is also increased. The speed is low, and the efficiency is low, and it is also easy to cause abrasions on the arms and arms of the sea catcher
