Automatic feed feeding and water changing device for fish breeding

Abstract

The invention relates to the field of biotechnology, and discloses an automatic feed feeding and water changing device for fish breeding. The automatic feed feeding and water changing device for fishbreeding comprises a fish tank, wherein a top cover is rotatably in clamping connection to the rear wall of the fish tank; a feed storing box is fixedly mounted at the upper part of the top cover; a sliding groove is formed in the rear wall of the fish tank; a mounting block is fixedly connected to the inner part of the left end of the sliding groove; a power shaft is rotatably mounted in the mounting block; and two supporting rods are rotatably in clamping connection to the inner part of the sliding groove. According to the automatic feed feeding and water changing device for fish breeding disclosed by the invention, the sliding groove, the mounting block, a power shaft, the supporting rods, folding gears, a linked rod and an arresting barrier are arranged, so that during water changing,fish can be automatically expelled to one corner; a part of old water is reserved, so that the situations that fish is lack of water, and or is unaccommodated with new water can be avoided, and breeding depletion is reduced; and a connecting frame, a cylinder, fixed blocks, connecting rods and a sealing plate are arranged, so that the fish can be automatically fed, labor is saved, the fish can grow healthy, and the economic benefits of a culturist are increased.

Description

technical field [0001] The invention relates to the field of biological technology, in particular to an automatic feeding and water changing device for fish breeding. Background technique [0002] Fish farming refers to the breeding, raising and stocking of fish, also known as aquaculture, fish farming and fish farming. It is very important to maintain food supply and keep the water quality in fish farming areas clean in fish farming. [0003] Most of the existing fish feeding and water changes are still artificial. Feeding is not only labor-intensive, but also has a serious impact on the growth of fish. During the process, the fish will face a short-term water shortage, and the new water will easily make the fish very uncomfortable. In severe cases, it will have a great impact on their health, increase the loss of breeding, and reduce the economic benefits of the breeder. . [0004] To this end, we have proposed an automatic feeding and water changing device for fish farm...
