Float type feeding device capable of floating or sinking for fish farming

Abstract

The invention discloses a float type feeding device capable of floating or sinking for fish farming. The float type feeding device comprises a barrel and a container in the barrel. The float type feeding device capable of floating or sinking is simple in structure as compared with the prior art; during use, the device sinks in water after enough sinkable feed is added on a floating board, the gravity applied to the floating board is reduced greatly as the feed on the floating board is swallowed by fish, the floating board made of light material raises due to buoyancy of water, water flows in each accommodating cavity as through holes between the floating board and accommodating cavity are opened, buoys are applied with force to drive the container to float, and then feed on the next floating board exposes for feeding fish; after enough floatable feed is added on the floating board, the feed can attach the upper portion of each accommodating cavity and floats along with the container after the accommodating cavity is filled with water, and then fish can eat the feed from below; and meanwhile the feed cannot disperse or spill and accordingly cannot be swallowed by birds. The float type feeding device capable of floating or sinking for fish farming has excellent effect.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a self-floating type floating and sinking dual-purpose feed feeding device for fish farming. Background technique [0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding management. In a broad sense, it can also include the proliferation of aquatic resources. [0003] Fish need to eat fish food to grow up. Among the various production inputs of aquaculture, feed input cost is the largest. According to the survey, the feed input cost of general aquaculture products accounts for more than 70% of the total cost of aquaculture. It is artificially throwing fish food into the fish pond for fish to eat, but when manually throwing fish food into the fish pond, it is time-consuming, laborious, long-...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a self-floating, floating and sinking dual-purpose feed feeding device for fish farming, which is simple in structure and easy to operate in order to solve the problems of single feeding and inconvenient recycling of equipment feed in the current aquaculture process , The production cost is low, it can realize the feeding of two types of feed, and it is easy to recycle
