Description

Automatic feeding equipment capable of slowly lowering fish feed particles

Technical Field

The utility model relates to the field of aquaculture equipment, in particular to automatic feeding equipment capable of slowly lowering fish feed particles.

Background

When fish aquaculture is carried out in water areas such as fishponds and lakes, farmers need to regularly feed so that fish fries can grow quickly, the growth speed of the fishes can be increased through artificial feeding, and the requirements of the market are met. The mode of feeding is thrown something and fed or the machine is automatic to be adopted to present fish fodder mostly, artifical throwing something and feeding is wasted time and energy, the machine is automatic to throw something and feed and is compared with artifical throwing something and feeding, although the efficiency of throwing something and feeding has been improved, the main function of the equipment of feeding is regularly shed fish fodder automatically, it is the same with artifical throwing something and feeding, can still cause partial fodder to sink to the bottom at the in-process of throwing something and feeding, cause the waste of fish fodder, the fish fodder that sinks simultaneously can also cause water pollution at the bottom deposit too much, influence the healthy growth of fish.

In particular, in the case of fish of interest in food intake, such as mandarin fish, ornamental fish, etc., it is particularly desirable to provide for the proper movement of the feed in the body of water while retarding the rate at which the fish feed pellets sink in the feeding water so as to enhance the food intake of the fish feed pellets by such fish of interest in food intake.

As is known, the mandarin fish is a freshwater edible fish, belongs to murder carnivorous fish, and usually takes other fishes as food, young fishes like fishes and shrimps, adult fishes mainly take fishes, and food intake is stopped in winter. The mandarin fish is rich in nutrition, delicious in taste and free of interspinous needling, so that the mandarin fish is deeply favored by people, the demand of the market for the mandarin fish is more and more large, and the naturally-growing mandarin fish can not meet the demand of people far away. Therefore, more and more aquaculture households depend on natural resources to perform ecological mandarin fish culture, feed needs to be put into the mandarin fish culture pond regularly during mandarin fish culture, and in the prior art, the feed is put into the mandarin fish culture pond manually, so that a large amount of manpower is wasted, the mandarin fish cannot keep normal activity, and the meat quality of the mandarin fish is influenced. Among them, the main reason is that mandarin fish has peculiar habit of ingestion, and mandarin fish only ingests fish feed particles moving in water, while mandarin fish does not ingest static fish feed particles floating on the water surface and sinking to the water bottom. And the mandarin fish can eat a part of fish feed particles in the process of sinking in water, and a considerable part of the fish feed particles can sink to the water bottom, so that waste is caused.

In order to solve the problem, some existing feeding machines are also provided with a water flow impacting device, namely water is sprayed to the water surface through a water discharge pipe at a feeding point, so that fish feed particles are impacted by the water flow to roll in the water, and the feeding interest of the mandarin fish to the fish feed particles is improved. Although the fish feed can sink in the upper water body along a rolling path under the impact of water flow above, after entering the middle water body, the fish feed particles still sink to the bottom of the water more quickly, and part of the fish feed particles sink to waste, so that the feeding efficiency is not high.
