Description

Technical Field

[0001] The invention relates to a three-dimensional amphibious circulation breeding device for amphibians. Background Art

[0002] There are many species of amphibians with high economic value and industrial development potential. For example, the artificial breeding of turtles and frogs has become a characteristic economy in many regions, especially bullfrogs, because they have edible advantages such as fast growth, delicious taste, rich nutrition, and high protein content. Their skin can be made into leather. The skin is thin, soft and tough, which is the material for making high-quality wallets, belts, ties, leather shoes, musical instruments, and surgical threads. The organs can be used to make medicines, and frog oil can be used to make high-grade lubricants. It has great economic value and has huge global market demand potential.

[0003] Traditional breeding technology is heavily dependent on large areas of natural water and soil resources, and even occupies farmland to build greenhouses and other backward breeding. Not only is the efficiency low and the quality poor, but it is also not conducive to farmland and environmental protection. The backward breeding technology has restricted the healthy development of the industry. In recent years, in order to solve this problem, people have carried out a lot of research and development of three-dimensional breeding technology, and have also achieved many scientific and technological achievements, such as application number 202111254242X a three-dimensional bullfrog breeding system and bullfrog waste purification method, 2023210958736 an improved circulating water bullfrog breeding device, 2022223807068 a green and antibiotic-free circulating water breeding device for bullfrogs, 202210403209 7 an automatic three-dimensional bullfrog breeding device and bullfrog breeding method and other technical equipment. However, through investigation and research on the current status of the industry, it is found that there are still many problems in the existing technologies including the above-mentioned technologies.

[0004] 1. In order to realize three-dimensional breeding, the existing three-dimensional breeding technology device sets a multi-layer bracket, generally at least two layers, and some have as many as five layers or more. Each layer is set as the same stocking platform. The platform structure has trough type, box type, and cage type. There are water bodies and frog habitat facilities on each platform. The hardware facilities look the same, but the growth environment is actually very different. Because the light, air temperature and humidity, and density composition of suspended matter on the upper and lower layers are different, the air circulation is poor, resulting in inconsistent growth environment on each layer of this three-dimensional breeding device, which is bound to seriously affect the quality of breeding.

[0005] 2. The water treatment system is complex and ineffective. Each layer has water flow facilities for animals to live, which will inevitably lead to complex and large water supply and decontamination facilities, increasing the cost of breeding.

[0006] The above two issues are the key factors affecting the development of three-dimensional farming and need to be solved urgently. Summary of the invention
