Oxygenation device for crab breeding

Abstract

The invention relates to the technical field of crab breeding, in particular to an oxygenation device for crab breeding. The oxygenation device comprises a box body, a protective frame, a ball screw,a first bevel gear, a rotating rod, a rotating disc, a grip, a second bevel gear, a ball nut, a support rod and an oxygenation mechanism, wherein the protective frame is fixedly connected to one sideof the inner wall of the box body, the ball screw is rotationally connected to the middle of the interior of the protection frame through a bearing, the first bevel gear fixedly is connected with thetop of the outer surface of the ball screw in a sleeved mode, the rotating rod is rotationally connected to the top of the middle of one side of the box body through a bearing, and the rotating disc is fixedly connected to one end of the rotating rod. Rotational motion can be converted into linear motion through cooperation of the ball screw and the ball nut, the oxygenation mechanism can be driven to move up and down through the supporting rod, the position of the oxygenation mechanism in the box body can be conveniently adjusted, oxygenation can be conveniently conducted on aquaculture waterat different depths in the box body, and the using effect is improved.

Description

technical field [0001] The invention relates to the technical field of crab cultivation, in particular to an aeration device for crab cultivation. Background technique [0002] Crabs, Animalia, Arthropoda, Crustacea, Molecula, Eucola, Decapod, Ventricula, Brachyura. It is a crustacean, the body is protected by a hard shell, and it breathes by gills. The body is rich in protein. Due to its delicious meat and various cooking methods, it has become a delicacy on the table in recent years. [0003] In order to stimulate economic benefits, many farmers use breeding boxes for breeding, which has low investment costs and is easy to fish. However, due to the small space in the breeding boxes and the low oxygen content in the water, it is not conducive to the growth of crabs. Therefore, farmers use oxygenation. The device ensures the oxygen content inside the breeding box. However, most of the current oxygenation devices are fixed inside the breeding box, which is not conducive to ...
