Constant-temperature rotary jet-type fish feed casting device

Abstract

The invention discloses a constant-temperature rotary jet-type fish feed casting device, structurally comprising a storage box, a solar panel, a spraying device, a box cover, a fixing rack, a fixing holding plate, fixing rings, and floaters. The storage box is arranged between the floaters and fixedly mounted above the fixing holding plate; the solar panel is embedded in the upper end of the box cover and electrically connected with the storage box. Compared with the prior art, the constant-temperature rotary jet-type fish feed casting device has the advantages that a constant-temperature cooling pipe and a circulating constant-temperature block provide constant temperature heat exchanging for feed in a storage bucket, external heat is isolated, the quality of the feed is maintained, proteins and necessary elements to compose the feed are avoided being damaged by high heat or the feed never cakes and blocks an outlet of the storage bucket due to low temperature, a retainer divides an air flow generated by an air pump to blow vortex blades so that a vortex blade block and a spray nozzle are rotated, the feed is scattered to the water surface around the device herein in a circular form, and it is avoided that fishes eat less and are even dead due to oxygen reduction of a water area caused by feed stacking in the area.

Description

technical field [0001] The utility model belongs to the field of fish farming equipment, and specifically relates to a constant temperature rotary jet fish feed feeding device. Background technique [0002] With the continuous development of science and technology, in order to follow up the increasing demand of the market and the high requirements of consumer groups, the traditional aquaculture industry is becoming more and more intelligent and mechanized, and has introduced various aquaculture equipment. Feed feeding device is also one of them. Its feeding forms include centrifugal type, air blowing type and falling type. It can be fed at fixed time, quantitative, fixed point, and automatically. It has the characteristics of saving labor and time, reducing feed waste, and protecting the water environment. , but the lack of consideration in the prior art is: [0003] 1. When feeding feed in the open-air pond, there is no shelter around it, and it is exposed to the sun for a...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a constant temperature rotary jet fish feed feeding device to solve the problem of easily destroying the protein, various elements and enzymes in the feed, so that the fish cannot absorb the necessary feed. nutrient, leading to their weight loss, physical decline, increased disease rate, and even death. Adding feed will cause them to accumulate in a fixed water area, causing all fish to tend to compete in this area, resulting in a decrease in the oxygen content of the water area. Fish eat less, or eat but stop growing, expending their own energy, causing weight loss, and suffocation when the oxygen content in the water falls below its minimum limit
