Crab breeding device

Abstract

The invention discloses a crab breeding device which comprises a first crab pond, a second crab pond, a third crab pond, support columns and hydraulic oil cylinders. The support columns are connectedwith the hydraulic oil cylinders, the first crab pond is arranged on the ground, the second crab pond is perpendicularly connected with the corresponding hydraulic oil cylinders on the ground by the corresponding support columns, the third crab pond is perpendicularly connected with the corresponding hydraulic oil cylinders on the ground by the corresponding support columns, hydraulic rods on thehydraulic oil cylinders can move in the up-down directions, and the support columns can be driven to act in the up-down directions. The crab breeding device has the advantages that the crab ponds canbe supported in midair by support plates, accordingly, the crab breeding areas can be enlarged, a large quantity of crab can be conveniently bred by users, each crab pond can be assuredly basked in sufficient sunlight, and earnings of the users can be increased; the heights of the hydraulic rods on the hydraulic oil cylinders can be adjusted according to requirements of the users on the heights ofthe crab ponds, and accordingly the height of the first crab pond and the height of the second crab pond can be changed; pipes are arranged in the support columns, and accordingly the crab ponds canbe conveniently filled with water by the users.

Description

technical field [0001] The invention relates to a three-dimensional culture device, in particular to a crab culture device. Background technique [0002] Crabs are rich in protein and trace elements, which have a good nourishing effect on the body. Crabs are known as "gutless men".
