Crushed material feeder for fishpond

Abstract

The invention provides a crushed material feeder for a fishpond. The crushed material feeder comprises a feeding unit and a storage unit at the upper end of a feeding mechanism. The storage unit comprises a cylindrical storage bin and a crushing mechanism at the upper end of the storage bin. The crushing mechanism comprises an electric lifting table at the top of the storage bin, a crushing motormounted on the electric lifting table and a plurality of horizontal blades mounted on a driving shaft of the crushing motor, and the driving shaft of the crushing motor vertically and downwardly extends into the storage bin. The bottom of the storage bin is provided with an electric valve, the feeding unit comprises a sending pipe connected to the lower portion of the storage bin and a rotary feeding mechanism arranged below the sending pipe, the rotary feeding mechanism comprises a horizontal rotating bin and a feeding motor which drives the horizontal rotating bin to rotate, and a pluralityof feeding pipes are radially distributed on the horizontal rotating bin. By the crushing mechanism, the size of feed particles is changed; by means of radial feeding, a feeding range is wide, and fish gathering can be prevented.

Description

technical field [0001] The technical field of fish pond cultivation of the present invention, in particular relates to a fish pond debris feeder. Background technique [0002] In the process of aquaculture, high-efficiency feeding technology is an extremely important link in aquaculture. Compared with traditional manual feeding, the fishery feeding machinery in the prior art has high feeding efficiency and greatly reduces labor intensity. However, there are still many deficiencies in the existing feeding machinery. Due to the diversity of feed varieties and the diversity of cultured fish, the size of feed particles cannot be changed according to actual needs; and the feeding range is small, resulting in a large number of fish. With the rapid increase of fish species, the dissolved oxygen in the regional waters dropped suddenly, and the PH, ammonia nitrogen, and nitrite indicators of the water quality also became abnormal, which induced the fish's physiological hypoxia and o...

Problems solved by technology

However, there are still many deficiencies in the existing feeding machinery. Due to the diversity of feed varieties and the diversity of cultured fish, the size of feed particles cannot be changed according to actual needs; and the feeding range is small, resulting in a large number of fish. With the rapid increase of fish species, the dissolved oxygen in the regional waters dropped suddenly, and the PH, ammonia nitrogen, and nitrite indicators of the water quality also became abnormal, which induced the fish's physiological hypoxia and often floated their heads, which not only hindered the growth of fish, but also made them susceptible to disease , what's more, it leads to the mass death of fish schools
