How to make automatic feeding fish

patent name manufacturing method of automatic feeder for fish tank technical field the invention relates to an automatic feeder for fish tank. Background art Because there is no complete food chain in the small environment of ordinary fish tanks, it is necessary to put feed into the fish tanks every day during the cultivation of ornamental fish. When family members travel for more than one day, they should entrust others to look after the fish in the fish tank. Their main job is to throw food into the fish tank on time. If there is a device that can automatically put feed into the fish tank on time, it can save a lot of manpower and material resources. Summary of the Invention The object of the present invention is to provide an automatic fish tank feeder which is simple in structure and convenient to use, and can quantitatively feed the fish tank on time. In order to achieve the above purpose, the invention adopts the following technical scheme: the automatic feeder for fish tanks comprises a container and a base, and is characterized in that the container is drum-shaped, a rotating shaft is arranged at the axial position of the container, a plurality of clapboards are arranged in the inner cavity of the container, the clapboards are uniformly distributed around the rotating shaft in a radial manner, a container feeding port is arranged on the outer circumferential wall of the container, and at least one container feeding port is arranged between two adjacent clapboards; The base is provided with a container sleeve capable of containing containers, the inner cavity of the container sleeve is matched with the outer circumference of the container, the inner wall of the container sleeve is provided with sealing strips, the number of the sealing strips is equal to that of the clapboards, the sealing strips are evenly distributed on the inner wall of the container sleeve along the circumference, and at least one jacket feeding port penetrating through the side wall of the container sleeve is arranged on the container sleeve; The rotating shaft is in transmission connection with the driving motor through a transmission mechanism. A driving shaft sleeve is installed in the center of the container sleeve through a bearing, the driving shaft sleeve is tubular, the lower end of the rotating shaft is inserted into the driving shaft sleeve, and the driving shaft sleeve is splined with the rotating shaft; The outer surface of the driving shaft sleeve is fixedly sleeved with a turbine, and the driving motor is in transmission connection with the turbine through a worm. The diameter of the upper end of the container is larger than that of the lower end. After adopting the technical scheme, under the control of the timer, the automatic feeder for fish tank can feed the fish tank regularly and quantitatively, thus solving the problem of raising ornamental fish when the owner goes out, replacing manual operation, saving time and labor.
