a fish feeding device

Abstract

The invention provides a fish feeding device, comprising a barrel and a buoy arranged on the barrel, wherein the barrel is internally provided with a cavity for placing fish food, and is also provided with a plurality of through holes; the barrel comprises an outer barrel and an inner barrel inserted into the outer barrel; an opening of the inner barrel is provided with a turned edge used for facilitating rotation; friction grains are arranged between the inner barrel and the outer barrel, and generate friction force, and when power generated when the turned edge is rotated is greater than the friction force, the inner barrel and the outer barrel can mutually rotate; the outer barrel and the inner barrel are provided with through holes which are corresponding in positions; the buoy is connected onto the outer barrel in a sleeved way and can slide up and down relative to the outer barrel; each of the outer barrel and the inner barrel is provided with a semicircular barrel bottom. The fish feeding device has the beneficial effects of effectively alleviating pollution of the fish food to water in a fish tank, reducing the waste of the fish food, adjusting a discharge rate of the fish food, increasing the exercise amount of fish, being low in manufacturing cost, being made of transparent plastic and facilitating watching.

Description

technical field [0001] The invention relates to the field of fishing gear, in particular to a fish feeding device. Background technique [0002] With the development and progress of society, more and more people use fish tanks to raise fish at home, but now the fish tanks basically put fish food directly into the fish tank, which not only accelerates the water pollution in the fish tank, but also a lot of fish This method of feeding fish is very inconvenient. Contents of the invention [0003] Aiming at the deficiencies of the existing technology, the invention provides a fish feeding device. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a fish feeding device, including a cylinder and a float, the float is arranged on the cylinder, the cylinder is provided with a cavity for placing fish food, and the cylinder is also provided with a There are several through holes. [0005] The cylinder includes an outer cylin...
