Breeding device capable of collecting fish excrement

Abstract

The invention discloses a breeding device capable of collecting fish excrement, and relates to the technical field of fish breeding devices. The breeding device comprises a device body, an excrement storing and discharging box, an excrement collecting screen, an opening and closing screen plate and an up-down sliding device, wherein the excrement storing and discharging box is arranged below the device body, and the excrement collecting screen is slidably connected with the inner wall of the device body through the up-down sliding device. The excrement collecting screen comprises water-permeable grids and excrement-permeable grids. The opening and closing screen plate comprises a water-permeable fixing block, excrement blocking plates are hinged to the two sides of the top of the water-permeable fixing block, water-permeable holes are fully distributed in the excrement blocking plates, the water-permeable fixing block is fixed below the water-permeable grids, and rotation of the excrement blocking plates on the two sides is used for controlling opening and closing of the excrement-permeable grids. Limiting plates are arranged at the bottom of the water-permeable fixing block towards the two sides in a protruding mode. Fish excrement can be rapidly and effectively cleared, the operation mode is simple and convenient, under the condition that fish breeding is not affected, the excrement-permeable grids are opened and closed under the action of resistance of water generated when the excrement collecting screen slides up and down on the excrement blocking plates, and thereforerapid and effective excrement collecting and clearing are achieved.

Description

technical field [0001] The invention relates to the technical field of fish farming devices, in particular to a farming device for collecting fish feces. Background technique [0002] Fish farming is also known as aquaculture, pisciculture and pisciculture. Through fish farming, many species have been successfully introduced to new areas. With the development of aquaculture in recent years, the development of fine farming techniques in high-density ponds Breakthroughs have been made, and the production of farmed fish has continued to increase. However, our country has also encountered a series of problems in the process of fish farming. At present, due to the high-density farming of farmers, fish feces cannot be cleaned quickly and effectively, which makes the environment of the culture water deteriorate rapidly, and the pollution increases, causing pathogenic bacteria The breeding of fish will increase the probability of fish disease, seriously affecting the quality of fis...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the fact that feces cannot be cleaned quickly and effectively during fish farming, which leads to rapid deterioration of the culture water environment and aggravated pollution, which leads to the growth of pathogenic bacteria and increases the probability of fish disease, which seriously affects the quality of fish. In order to improve the quality of fish products, a breeding device for collecting fish feces was proposed.
