Large-scale crab culture system

Abstract

The invention relates to the technical field of aquaculture, and discloses a large-scale crab culture system. The large-scale crab culture system comprises a culture tank, wherein a funnel is fixedlyconnected with the interior of the culture tank, a fixing cylinder with an open end is fixedly connected with inner side walls of the culture tank, an output end of the funnel communicates with a cylinder wall of the fixing cylinder, a plugging block is slidingly connected with the interior of the fixing cylinder, an inner threaded pipe is fixedly connected with the side wall, away from the outputend of the funnel, of the plugging block, a threaded rod is connected with the interior of the inner threaded pipe through threads, a first motor is installed on an outer side wall of the culture tank, and an output end of the first motor is connected with one end of the threaded rod through a coupler. According to the large-scale crab culture system, crab excrement or impurities which are stacked on the bottom of the culture tank can be discharged, the crab excrement and the impurities can be conveniently cleared completely and thoroughly, effects on a culture environment of crabs are avoided, and crab feed can be evenly and automatically sprinkled over the interior of a culture cage, so that breeding of the crabs is facilitated.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a large-scale crab breeding system. Background technique [0002] Crab is one of the common foods in life. Because it is rich in protein, vitamin D and trace elements, it has a good nourishing effect on the body, so it is very popular in the market. Therefore, there are more and more crab breeding enterprises, and the output of crabs is increasing, allowing large-scale farming. This is because while the supply of crabs increases, along with the increasing needs of people's living standards, the demand for crabs also increases significantly, which also greatly stimulates the further development of crab farming. [0003] The Chinese patent authorization announcement number is CN204120009U, which discloses a crab breeding system, which has the advantages of increasing the oxygen content of the water body, observing the breeding environment in real time, improving the water qual...

AI Technical Summary

Problems solved by technology

[0005] In view of the deficiencies in the prior art, the present invention provides a large-scale crab breeding system, which can clean up all the excrement or impurities accumulated at the bottom of the breeding pond, and can evenly and automatically sprinkle the crab feed into the breeding cage. It is beneficial to the breeding of crabs, and solves the problem that it is difficult to clean up all the excrement and impurities of crabs, which affects the breeding environment of crabs, and cannot evenly and automatically sprinkle the feed of crabs into the breeding cages.
