Description

Technical Field

[0001] The invention relates to the technical field of fish fry cultivation, in particular to a hatching tank capable of preventing fish fry from sticking to a net. Background Art

[0002] Although the cultivation time from fry to fingerlings is very short, their survival rate and physical condition have a great influence on the cultivation effect of the entire fish species, so they must be taken seriously. In the early stage of fry cultivation, the fry need to be placed in the hatching and culture tank. During the cultivation process of fry, water needs to be constantly replenished to form flowing water. Nowadays, water is generally discharged directly into the tank through a water pipe. However, the impact force of water discharged directly into the tank is large, causing the water flow to drive the fry toward the barrier net, resulting in a large number of fry hanging on the barrier net, causing them to die, which greatly reduces the survival rate of the fry. Summary of the Invention

[0003] The purpose of the present invention is to provide a hatching tank which can prevent fry from sticking to the net, so as to solve the above-mentioned problem.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] The present invention provides a hatching tank for preventing fry from sticking to a net, comprising a tank body, a bracket installed on the top of one end of the tank body, a filter buffer assembly connected to the bracket, an internal connection of an intercepting net at one end of the tank body away from the bracket, a reverse thrust assembly provided on the side of the intercepting net away from the bracket, and a drain pipe connected to the end of the tank body close to the reverse thrust assembly.

[0006] Furthermore, the filter buffer assembly includes a basket, a plurality of leakage holes are opened at the bottom of the basket, and a buffer sponge is provided inside the basket.

[0007] Furthermore, a filter is connected to the center of the bracket.

[0008] Furthermore, the blocking net is connected to the plug plate, and both ends of the plug plate are respectively inserted into the first slots opened on the inner wall of the tank body.

[0009] Furthermore, the reverse thrust assembly includes a self-priming pump installed in the trough body, the water outlet end of the self-priming pump is connected to the round-shaped pipe through a connecting pipe, the round-shaped pipe is connected to the inner wall of the trough body, and a plurality of cross pipes are connected to the round-shaped pipe. The end surface of the round-shaped pipe and the cross pipe close to the barrier net are provided with a plurality of water outlet holes.

[0010] Furthermore, two symmetrically arranged second slots are provided on the inner wall of the tank body, and the side ends of the circular tube are inserted into the second slots.

[0011] Compared with the prior art, the present invention has the following beneficial technical effects:

[0012] The present invention buffers the water discharged into the basket through the buffer sponge, so as to prevent the water from directly rushing into the tank body, reduce the impact force, and filter the water source. In addition, through the backflush component, the water is rushed to the barrier net through the self-priming pump through the circular pipe and the horizontal pipe, thereby offsetting the impact force generated by the water falling into the tank body from the water supply end, and can flush down the fry hanging on the barrier net, thereby greatly improving the survival rate of the fry.

DETAILED DESCRIPTION

[0020] like Figure 1-5 As shown, a hatching tank for preventing fry from sticking to the net includes a tank body 1, a bracket 2 is installed on the top of one end of the tank body 1, and a filter screen 6 is connected to the center position of the bracket 2.

[0021] The bracket 2 is connected to a filter and buffer assembly, which includes a basket 4 with a plurality of leak holes at the bottom. A buffer sponge 5 is located within the basket 4. During use, the water supply pipe is placed on the buffer sponge 5, allowing water from the water supply pipe to be buffered by the buffer sponge 5 and then slowly fall into the tank 1, reducing the impact of water entering the tank 1. The buffer sponge 5 also filters the water source and prevents impurities from entering the tank 1.

[0022] A barrier net 3 is connected to the end of the tank body 1 away from the bracket 2. The barrier net 3 is connected to an insert plate 7. The two ends of the insert plate 7 are respectively inserted into first slots 8 provided on the inner wall of the tank body 1. The barrier net 3 separates the tank body 1 into an area with fry and an area without fry.

[0023] A reverse thrust assembly is provided on the side of the barrier net 3 away from the bracket 2 , and a drain pipe 15 is connected to one end of the tank body 1 close to the reverse thrust assembly, through which water in the fry-free area of the tank body 1 is discharged.

[0024] The reverse thrust assembly includes a self-priming pump 9 installed in the tank body 1. The water outlet end of the self-priming pump 9 is connected to a circular pipe 11 through a connecting pipe 10. The circular pipe 11 is connected to the inner wall of the tank body 1. Two symmetrically arranged second slots 14 are provided on the inner wall of the tank body 1. The side ends of the circular pipe 11 are inserted into the second slots 14. The circular pipe 11 is connected to a plurality of transverse pipes 12. A plurality of water outlet holes 13 are provided on the end surface of the circular pipe 11 and the transverse pipe 12 near the barrier net 3.

[0025] The self-priming pump 9 sucks water into the end of the tank away from the fry, and then discharges the water into the circular pipe 11 and the horizontal pipe 12 through the water outlet end, and then discharges the water toward the barrier net 3 through the water outlet hole 13, so that the discharged water backwashes the barrier net 3, offsets the impact force generated by the water supply, and can also flush down the fry hanging on the barrier net 3, preventing the fry from hanging on the barrier net 3 and causing death.

[0026] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by persons skilled in the art should fall within the scope of protection defined by the claims of the present invention.
