Abstract

The invention provides a suction type crab catching device comprising a vacuum sucker. The top of the vacuum sucker is connected with a pipe connector; a side branch of the pipe connector communicates with a vacuum connector; the lower end of a supporting rod is mounted in a threaded connection hole in the top of the pipe connector via threads; a vacuum generator is installed on the supporting rod; the vacuum generator is connected with the vacuum connector on the side of the pipe connector via a pipeline. The suction type crab catching device is simple in structure and convenient to use; with the device, workers do not need to stoop to catch crabs with hands directly, so that the work safety is improved and the crab catching efficiency is increased.

Description

technical field [0001] The invention relates to the field of crab-catching devices, in particular to an adsorption-type crab-catching device. Background technique [0002] In crab farming, crabs can be caught after they mature from September to October every year. Crab nets or crab cages can be used to catch crabs in the water, or they can be caught when crabs come ashore at night. In the prior art, night crabs rely on the staff to catch the crabs by hand, which is poor in safety and requires bending over, which will adversely affect the health of the staff. Contents of the invention [0003] The purpose of the present invention is to provide an adsorption type crabbing device to solve the problems in the prior art of artificial crabbing at night. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] An adsorption crabbing device, characterized in that it includes a vacuum suction cup made of silicone rubber mat...
