Fish fry feeding device

Abstract

The invention relates to the field of fish fry farming, and particularly relates to a fish fry feeding device which comprises a storage structure and a rotating component, wherein the storage structure and the rotating component are combined by a support frame and arranged beside a farming hard pool; when fish fries need to be fed, an outlet end of the storage structure is propped against a rotating platform of the rotating component, then a feed is poured into a filling cylinder of the storage structure, and then a sliding rod slides downward, so that a gap is reserved between the rotating platform and the outlet end of the storage structure; when the rotating platform is rotated, convex bars on the rotating platform can gradually extrude the feed out from the gap between the outlet end of the storage structure and the rotating platform, a U-shaped rod of a material poking bar can block the feed on an outermost edge, and the feed drops from a side edge of the rotating platform to a farming pool when the feed is stacked to exceed a diameter range of the rotating platform so as to achieve a purpose of feeding automatically and quantitatively; and the fish fry feeding device furtherhas advantages of farming acceleration and convenience.

Description

technical field [0001] The invention relates to the field of fry breeding, in particular to a fry feeding device. Background technique [0002] Today's research results in aquaculture are quite fruitful. At present, there have been remarkable achievements in the improvement of species of farmed fish and the improvement of farming techniques; During the breeding process, pay attention to the change of water quality and the way of fish feeding, so as to avoid the large difference in water quality from affecting the growth of fry, and even causing the death of fish; moreover, there are many factors to change the water quality of aquaculture ponds, in addition to being affected by environmental temperature, fish In addition to the impact of fish excrement, feeding too much bait is also a factor for water quality deterioration. Therefore, the early fish farming method was to manually quantify bait in a specific period of time according to the number and size of fish schools to be...

[0002] Today's research results in aquaculture are quite fruitful. At present, there have been remarkable achievements in the improvement of species of farmed fish and the improvement of farming techniques; During the breeding process, pay attention to the change of water quality and the way of fish feeding, so as to avoid the large difference in water quality from affecting the growth of fry, and even causing the death of fish; moreover, there are many factors to change the water quality of aquaculture ponds, in addition to being affected by environmental temperature, fish In addition to the impact of fish excrement, feeding too much bait is also a factor for water quality deterioration. Therefore, the early fish farming method was to manually quantify bait in a specific period of time according to the number and size of fish schools to be reared. Feeding operations to achieve the purpose of controlling the amount of bait fed; however, such an operation method requires more labor costs and does not meet modern needs. Therefore, the present invention provides a fish fry feeding device
