Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to an aquaculture fish fry hatching device. Background Art

[0002] With the development of aquaculture, the requirements for fish fry hatching technology are also increasing.

[0003] Traditional fish fry hatching devices often have problems such as poor water quality management, insufficient dissolved oxygen in the water, and uneven distribution of nutrients. These problems directly affect the hatching rate of fish eggs and the survival rate of fish fry, thereby restricting the further development of aquaculture.

[0004] Most of the fish fry hatching devices on the market currently have water circulation and filtration systems, and also need to set up a separate oxygen pump to increase the dissolved oxygen in the water. When adding nutrients, adding them from a single location can easily lead to uneven distribution of nutrients, resulting in a less than ideal growth environment for fish eggs and fry. For this reason, we propose an aquaculture fish fry hatching device. Utility Model Content

[0005] The purpose of the utility model is to provide an aquaculture fish fry hatching device to solve the problems raised by the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an aquaculture fish fry hatching device, comprising a water tank and a circulation tank, a first water pump is installed on one side of the circulation tank, a water pipe is connected to the bottom of the water tank, one end of the water pipe is connected to the water inlet of the first water pump, a second water pump is installed on one side of the circulation tank, a soft water pipe is connected to the water outlet of the second water pump, a nozzle is fixedly installed on one end of the soft water pipe, and a moving component for supporting the nozzle is installed on one side of the water tank;

[0007] A plurality of limit blocks are fixedly installed inside the water tank, a fish egg box is slidably installed inside the limit blocks, a support member abutting against the limit blocks is installed on one side of the fish egg box, and a plurality of exchange holes are opened on the bottom surface of the fish egg box.

[0008] Preferably, the moving component includes a linear motor, which is fixedly mounted on one side of the water tank. An L-shaped mounting plate is fixedly mounted on the moving end of the linear motor. The nozzle passes through the L-shaped mounting plate, and the L-shaped mounting plate is fixed to the nozzle.

[0009] Preferably, the support member is specifically a plurality of support rods, the support rods are fixedly mounted on the top surface of the fish egg box, and one end of the support rods is in contact with the top surface of the limit block.

[0010] Preferably, the nozzle is located above the water tank.

[0011] Preferably, a filter screen is installed in the inner cavity of the circulation box.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The aquaculture fry hatching device, turns on the switches of the first water pump and the second water pump, the first water pump pumps the water in the water tank into the circulation box through the water pipe, the second water pump draws the water in the circulation box through the soft water pipe and sprays it back into the water tank through the nozzle, thereby realizing water circulation. During the water circulation process, the filter net has a filtering effect, filters impurities in the water to prevent them from returning to the water tank, and when the nozzle sprays water back to the water tank, the sprayed water can increase the dissolved oxygen content in the water in the water tank, so that only the water circulation system is needed to automatically increase the dissolved oxygen content in the water to ensure the normal hatching of fish eggs.

[0014] 2. In the aquaculture fish fry hatching device, after adding nutrients into the circulation box, the nutrients will be sprayed out from the nozzle as the water circulates. Turning on the switch of the linear motor drives the L-shaped mounting plate to move back and forth horizontally, thereby continuously changing the spraying position of the nozzle, so that the nutrients can be quickly dispersed, ensuring that the nutrients in the water are uniform, and preventing the hatching of fish fry from being affected.
