Mobile shrimp-crab breeding oxygenator

Abstract

The invention discloses a mobile shrimp-crab breeding oxygenator which comprises an airbag, a sleeve, a cover, three supporting rods, a protecting plate, a motor, a bottom plate, a mounting seat, a fixed shaft, stirring blades, a rotating shaft, a base, bolts, a paddle and a protecting cover. The mounting seat is arranged in the middle of the bottom plate, the motor is arranged on the mounting seat, the rotating shaft is arranged at the bottom of the motor, the output end of the motor is in transmission connection with the rotating shaft, the protecting plate is arranged at the top of the motor, the three supporting rods are arranged on the outer side of the bottom plate, one ends of the three supporting rods are fixedly connected on the outer side wall of the bottom plate, the protectingcover is arranged at the bottoms of the supporting rods, the rotating shaft is arranged inside the protecting cover, the sleeve is arranged at the other ends of the supporting rods, the airbag is arranged on the sleeve, the cover is arranged at the top of the airbag, the base is arranged at the bottom of the rotating shaft, the stirring blades are arranged around the bottom of the base, one end ofeach stirring blade is provided with a through hole, and a threaded hole is formed in the base corresponding to the through holes of the stirring blades.

Description

technical field [0001] The invention relates to the technical field of shrimp and crab cultivation equipment, in particular to a mobile shrimp and crab cultivation aeration machine. Background technique [0002] Shrimp and crabs are another family of arthropods, which belong to the order Decapod of crustacea. These animals are closely related to humans. Some are the main aquaculture or fishing objects, especially shrimps, lobsters and crabs. The output of my country's marine fishery catches is quite large, especially prawns, hairy shrimps, swimming crabs, etc., which are rich in nutrition, high in output value, and more important in status. There are many types of shrimps and crabs in my country. There are more than 1,000 species, including more than 400 species of shrimp and more than 600 species of crab. Water quality control is the key to shrimp and crab farming. Water is added once every 2-3 days in the high temperature season. Take oxygen-increasing measures. During the w...

Problems solved by technology

[0003] Generally, the aerators used for aquaculture mainly move the water surface by the rotation of the blades, so that the air naturally enters the fish pond. However, the amount of oxygen added by the traditional aerators is quite limited. It can increase oxygen for local areas of the water surface, but its oxygenation range is limited and cannot achieve good circulation of deep water flow. In addition, although the oxygenation range of traditional jet flow aerators is increased, its structure still cannot allow water flow to achieve sufficient circulation. , the gas brought into the pool cannot be fully diffused at the bottom of the pool, the gas forms larger bubbles, and then emerges from the water surface, and the oxygenation effect is not good. Therefore, a mobile shrimp and crab breeding aerator is proposed.
