Fishery water surface floating feeding device

Abstract

The invention discloses a fishery water surface floating feeding device which comprises a floating cylinder, wherein the upper end of the floating cylinder is sleeved by a driving motor; the driving motor is connected with a vertically arranged rotating shaft; the upper end of the rotating shaft is sleeved by a feeding hopper; the feeding hopper is of a columnar hollow structure; the feeding hopper is provided with a plurality of feeding tubes; a discharge tube is arranged above the feeding hopper; the upper end of the discharge tube is sleeved by a containing cylinder; a plurality of reinforcing support rods are arranged between the containing cylinder and a floating cylinder. Due to adoption of the floating cylinder which can float on a water surface, the device is capable of achieving moveable feeding, is large and uniform in feeding area, high in feed utilization rate, in addition simple in structure, low in manufacturing cost and easy to achieve, the anoxic phenomenon caused by partial dense feeding can be avoided, feed inside the containing cylinder can be thrown smoothly from the feeding hopper under the action of centrifugal force generated when the motor is rotated, waterpollution caused by crushed feed can be avoided, and the economic benefits of aquaculture can be increased.

Description

technical field [0001] The invention relates to a feeding tool for fishery, in particular to a water surface floating feeding device for fishery. Background technique [0002] With the improvement of people's living standards, the demand for aquatic products in the market is increasing. In aquatic products, compound feeds are widely used. Reasonable selection of feeds and high-efficiency feeding techniques have become extremely important links in aquaculture. The traditional feeding method mainly relies on manual feeding, which is time-consuming and labor-intensive. Mechanical feeding machines have emerged as the times require. [0003] At present, the mechanical feeding machine usually builds a feeding platform about 10 meters away from the shore of the pond, and manually transports the feed into the feeding machine for feeding, which is costly; Fan-shaped, fixed feeding, fixed one-way flapping feeding, small feeding area, fish and shrimps tend to be dense when they are gr...

The traditional feeding method mainly relies on manual feeding, which is time-consuming and labor-intensive. The mechanical feeding machine came into being

[0003] At present, the mechanical feeding machine usually builds a feeding platform about 10 meters away from the shore of the pond, and manually transports the feed into the feeding machine for feeding, which is costly; Fan-shaped, and fixed feeding, fixed one-way flapping feeding, feeding area is small, fish and shrimp are likely to be crowded when they are grabbing food, resulting in local hypoxia, low feed feeding rate, and broken feed will also cause water pollution, reduce Economic benefits; in addition, the feed in the feeding box flows downwards by gravity, and agglomeration in the feed will block the outlet, resulting in failure to feed normally
