Description

Automatic fish feeding device

Technical Field

The invention relates to a fish feeding device, in particular to an automatic fish feeding device realized by utilizing physical and mechanical principles.

Background

Because a complete food chain does not exist in the small environment of the common fish tank, feed needs to be put into the fish tank every day in the cultivation process of the ornamental fish. First, the time and amount of artificial feeding may be unscientific, resulting in fish overeating and death. Secondly, after the fish in the fish tank is fed with the special fish food, if the fish is not eaten in time, the residual granular fish food can be softened and decomposed under the condition of disappearance and soaking, so that the water becomes turbid. If the fish tank is provided with the device which can automatically put feed into the fish tank and immediately remove residual fish food, a large amount of manpower and material resources can be saved.

A conventional automatic fish feeding device generally adopts an electric principle, calculates timing through a central processing unit, and controls an actuating mechanism to move so as to pour bait into a fish tank, for example, a patent with the application number of 200910191893.1 discloses a timing automatic feeding fish tank which comprises a feeding device and a timing device. The feeder is arranged at the top of the fish tank, and the timing device is arranged on the outer wall of the fish tank. After a timing switch of the timing device is set, the feeder starts to feed automatically when the preset time is up. After the default time, the feeder is closed, and feeding is finished. The devices have complex circuit structures, low safety, standby power consumption of the central processing unit and high cost for specially setting the execution mechanism. In search, patent with application number 201410319440.3 discloses an environment-friendly fish tank feeder, which employs fish food belts for feeding bait in a relatively novel manner, but the disadvantages are too obvious, and firstly, the most important point is that the fish tank feeder cannot feed automatically, and the fish tank feeder needs to rely on the continuous rotation of double turntables in the same direction to feed the fish food belts; secondly, the bait is soaked in water for a long time, even the feeding wheel and the receiving wheel are partially in the water, and the bait is easy to deteriorate; thirdly, most of the fish food belt is only close to the water surface, and the fish can not effectively take food.
