Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] The utility model aims to provide a batch hatching bucket for debonded fish eggs, so as to solve the problems existing in the prior art, facilitate artificial propagation of debonded fish eggs and improve hatching effect.
[0019] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0020] like Figure 1As shown, the present embodiment provides a batch hatching barrel for debonding fish eggs, comprising a barrel body 1, a water supply pipe 2, a spoiler pipe 5, an air supply pipe 8 and a drainage element. The upper end of the barrel body 1 is open, so that the situation in the barrel body 1 can be observed from top to bottom. One end of the water supply pipe 2 is connected to an external water supply device for continuously introducing water into the barrel body 1. The other end of the water supply pipe 2 is connected and communicated with a first branch pipe 3 and a second branch pipe 4. One end of the first branch pipe 3 extends toward the bottom of the barrel body 1 to communicate with the spoiler pipe 5. The spoiler pipe 5 is located on the inner bottom surface of the barrel body 1. A plurality of water outlet holes 6 are provided on the spoiler pipe 5, and then water is introduced into the spoiler pipe 5 through the water supply pipe 2 and the first branch pipe 3, and the water in the spoiler pipe 5 flows out through the water outlet holes 6, thereby disturbing the water at the bottom of the barrel body 1, and then disturbing the entire water body of the barrel body 1, so as to avoid the fertilized eggs from piling up and affecting the hatching efficiency. In order to improve the hatching rate and hatching effect, one end of the second branch pipe 4 extends to the drainage element, the upper end of the drainage element is located at the upper end opening of the barrel body 1, and the lower end of the drainage element extends to the lower end of the barrel body 1 and extends out of the lower bottom surface of the barrel body 1. A filter screen 10 is arranged at the upper end of the drainage element. The setting of the filter screen 10 can prevent the fish eggs from being accidentally discharged from the barrel body 1. The second branch pipe 4 can pass water to the upper end of the filter screen 10, and discharge the water from the barrel body 1 through the drainage element, thereby realizing the drainage function and the water level control function. At the same time, in conjunction with the water supply pipe 2, automatic circulation water change can be realized to ensure the fresh water quality in the barrel body 1, and the accumulation of fertilized eggs can be avoided without a medium. One end of the air supply pipe 8 extends to the inner bottom surface of the barrel body 1. While supplying oxygen to the inner bottom of the barrel body 1, gas turbulence is also realized to a certain extent, so that each fish egg can get sufficient oxygen.
[0021] Specifically, the main body of the barrel 1 is a cylinder, the lower part of the barrel 1 is conical, and the inner wall of the barrel 1 is smooth without dead angles. The air outlet of the air supply pipe 8 is located at the bottom of the barrel 1, and the fish eggs that may fall on the bottom of the cone are blown up for hatching, so as to avoid the accumulation of fish eggs and mold caused by insufficient oxygen. At the same time, the oxygen supply at the bottom can ensure that the entire barrel 1 can be supplied with oxygen and the oxygen is sufficient.
[0022] The spoiler pipe 5 is a PVC straight pipe, which is horizontally placed at the bottom of the barrel body 1, and the spoiler pipe 5 is aligned with a diameter of the ground inside the barrel body 1. The water outlet holes 6 are arranged along the length direction of the spoiler pipe 5 and are located on the same side. When water is supplied, the water can flow in the barrel body 1 in a clockwise direction after flowing out through the water outlet holes 6 to avoid the accumulation of fish eggs. At the same time, the water outlet holes 6 on the same side can ensure that the water flows out on the same side, and the regular circulation flow can prevent the irregular water flow from causing damage to the fish eggs.
[0023] The first branch pipe 3 is provided with a valve 11 for controlling the water flow in the first branch pipe 3. The valve 11 can be used to determine whether the rotating nozzle discharges water and the size of the water flow rate. The first branch pipe 3 is provided with a plurality of rotating nozzles at one end away from the water supply pipe 2. The rotating nozzles can rotate and spray water into the drainage element to clean the filter 10, thereby preventing impurities, egg membranes, etc. from clogging the filter 10, resulting in poor water circulation, and also preventing fish eggs from adhering to the filter 10.
[0024] The drainage element includes a funnel 9, a drain pipe 7 and a filter 10. The funnel 9 is installed at the upper end of the drain pipe 7 and is connected to the drain pipe 7. The drain pipe 7 extends to the bottom of the barrel body 1 and extends out of the barrel body 1 to realize water circulation. A plurality of drainage windows are provided on the side wall of the funnel 9. A filter 10 is installed in each drainage window. A shielding element can also be covered above the funnel 9 to prevent fish eggs from entering the funnel 9 to a certain extent.
[0025] The specification of the filter screen 10 is 120 mesh, and those skilled in the art can also adjust its specification according to actual needs.
[0026] A plurality of legs 12 are circumferentially mounted on the lower end of the barrel body 1 to achieve installation and fixation of the barrel body 1 .
[0027] When it is necessary to continuously supply water to a plurality of barrel bodies 1 , the water supply pipes 2 on adjacent barrel bodies 1 can be connected and communicated.
[0028] After the fish eggs are debonded, they are hatched in a batch hatching bucket of the debonded fish eggs in this embodiment. The whole process continuously and automatically circulates and changes water, does not require a medium, and the fish eggs are not piled together. Each fish egg can have sufficient oxygen and fresh water quality, and the hatching rate is high and the hatching quantity is large. A barrel body 1 with a height of 1.5 meters and a diameter of 1 meter is selected, and 2 million fish eggs can be hatched in each batch.
[0029] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of the present invention. At the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
