Fish feed throwing device floating on water surface

Abstract

The invention discloses a fish feed throwing device floating on a water surface. The fish feed throwing device comprises a ship hull, a base, a feed conveying barrel and a feed lifting barrel. The base, the feed conveying barrel and the feed lifting barrel are sequentially arranged on the top surface of the ship hull from the left to the right, a first motor is arranged on the base, a conveying shaft is arranged in the feed conveying barrel, a propelling blade sleeves the conveying shaft, a stirring barrel is arranged on the left side of the top of the feed conveying barrel, a third motor is embedded in the bottom wall of the feed lifting barrel, a rotary shaft is fixedly connected with a motor shaft of the third motor, an auger sleeves the rotary shaft, a rotary barrel is rotationally connected with the top of the outer circumferential surface of the feed lifting barrel by a third bearing, a centrifugal disc sleeves the bottom of the outer circumferential surface of the rotary barrel, and a plurality of discharge pipes which are matched with the centrifugal disc are uniformly communicated and connected with the upper portion of the wall of an inner cavity of the feed lifting barrel in the circumferential directions. The fish feed throwing device has the advantages that fish feed and nutrition additives can be stirred by the stirring barrel, accordingly, the fish feed can be mixed, and uniform nutrition of the fish feed can be guaranteed; the fish feed can be sprayed by the aid of the centrifugal disc at 360-degree angles without dead angles, and accordingly the fish feed throwing device is wide in spraying range.

Description

technical field [0001] The invention relates to the technical field of fish farming equipment, in particular to a fish material throwing device floating on the water surface. Background technique [0002] For fish farming in ponds, the main breeding techniques include polyculture and close-breeding, round fishing and shifting, daily management and comprehensive management. China's pond fish farming now ranks first in the world in terms of total output, aquaculture area, and average yield per unit of concentrated contiguous fish ponds. [0003] At present, in the practice of fish farming, the fish in the fish pond are usually fed by artificial throwing. It is a very tiring and time-consuming task for the breeder to feed the fish ponds of tens of acres or even dozens of acres. It is laborious, so not only the work efficiency is low, but also the labor intensity is high. At the same time, the fish feed sprinkled is not uniform enough, and the fish feed cannot be evenly dispers...

Problems solved by technology

[0003] At present, in the practice of fish farming, the fish in the fish pond are usually fed by artificial throwing. It is a very tiring and time-consuming task for the breeder to feed the fish ponds of tens of acres or even dozens of acres. It is laborious, so not only the work efficiency is low, but also the labor intensity is high. At the same time, the fish feed sprinkled is not uniform enough, and the fish feed cannot be evenly dispersed in the pond. The fish will be crowded and scrambled during eating, which will cause the water in the pond to change. If the fish is turbid, including sediment, floating objects, etc., the fish will breathe some impurities into the body during the breathing process, which will cause the fish to get sick
