[0002] In the process of breeding striped bream fry, it is necessary to remove the excrement and food residues of the fry every other day in the early stage; as the fry's food intake increases, it is necessary to remove the excrement and food residues of the fry every day; generally, the siphon method is used to suck out the waste manually, and the above operation process will interfere with the fry;

[0003] In the prior art, after the body length of striped porgy fry reaches 5cm, it can be used as mature fry for breeding. However, the fry breeding rate of striped porgy fry can only reach 10%, which is inseparable from the interference effect of sewage absorption on the fry. Summary of the invention

[0007] In the initial state, each of the waste switch conversion ports of the present invention is aligned with each of the waste inlets; water is filled into the lower cavity, so that the waste discharge device sinks to the bottom of the pool below the oxygen generator, and a sealing cover is covered on the left joint and the right joint; under the action of gravity, the excrement and food residues of the fry enter the upper cavity through each of the waste inlets and the waste switch conversion ports;

[0008] After 1 day or several hours, the dirt accumulated in the upper cavity gradually increases, and pressurized tap water is injected into the sewage inlet. The pressure of the tap water pushes the rubber sliding sealing plate toward the nut of the limit screw and limits it, so that each dirt switch conversion port and the corresponding dirt inlet are misaligned, and the pressure of the tap water opens the water incision, and the water flows into the upper cavity through the water incision;

[0009] Under the action of water pressure, the rubber sliding sealing plate is pressed against the top of the upper cavity, and the sewage is discharged out of the breeding pond through the sewage outlet and the sewage hose;

[0010] When there is no dirt in the water discharged from the hose, the staff stops injecting tap water into the sewage inlet, and the rubber sliding seal automatically resets.

[0011] Therefore, the present invention can automatically collect excrement and food residues of fry, and when the dirt accumulated in the upper cavity is removed, each dirt switch conversion port is misaligned with the dirt inlet corresponding thereto, and the rubber sliding sealing plate is against the top of the upper cavity, so that the water flow will not escape from the dirt inlet, and the fry will not be disturbed by the dirt; thus, the dirt can be collected and removed in time without affecting the fry, and the requirement of the culture pond on the dirt cleaning frequency can be met, thereby providing a reliable basis for improving the breeding rate of fry.

[0012] Preferably, the right part of the left cover is provided with an upper left groove and a lower left groove which are respectively connected with the upper cavity and the lower cavity and open to the right, and the left part of the right cover is also provided with a lower right groove which is connected with the lower cavity and open to the left; the lower part of the sewage outlet is connected with the upper left groove.

[0013] The setting of the upper left groove makes the sewage flow more smoothly and improves the efficiency of removing dirt;

[0014] The arrangement of the lower left groove and the lower right groove increases the volume of the lower cavity, and the lower cavity can accommodate more air or water, so that the present invention can be stably suspended in water or sunk to the bottom of the breeding pond.

[0015] Preferably, the rubber sliding sealing plate includes a top plate, a front vertical plate connected to the front edge of the top plate, and a rear vertical plate connected to the rear edge of the top plate; each waste switch conversion port is located on the top plate.

[0016] The structural arrangement of the top plate, the front vertical plate and the rear vertical plate enables the rubber sliding sealing plate to better abut against the top of the upper cavity and seal each dirt inlet after each dirt switch conversion port and the corresponding dirt inlet are misaligned.

The water flow drives the excrement and food residues of the fry into the upper cavity through various dirt inlets and dirt switch conversion ports. Due to the slow water flow, it will not affect the fry.

[0021] Preferably, the dirt inlet is strip-shaped, and the cross section of the dirt inlet is funnel-shaped and upwardly open. The funnel-shaped dirt inlet is convenient for the excrement and food residues of the fry to enter the upper cavity, and the dirt is not easy to leave the upper cavity through the dirt inlet.

[0025] Because dirt is more likely to accumulate around the oxygen generator, the sewage discharge device of the present invention is placed below the oxygen generator.

[0026] Step 2, under the action of gravity, the excrement and food residues of the fry enter the upper cavity through each waste inlet and the waste switch conversion port;

[0027] Step 3, after a period of time, the dirt accumulated in the upper cavity gradually increases, and the staff injects pressurized tap water into the sewage inlet through the water inlet hose. The pressure of the tap water pushes the rubber sliding sealing plate toward the nut of the limit screw and limits it, so that each dirt switch conversion port and the corresponding dirt inlet are misaligned, and the pressure of the tap water opens the water incision, and the water flows into the upper cavity through the water incision;

[0028] Under the action of water pressure, the rubber sliding sealing plate is pressed against the top of the upper cavity, and the water flow will not escape from the sewage inlet, so that the fry will not be disturbed by the sewage; the sewage is discharged out of the breeding pond through the sewage outlet and the sewage hose;

[0029] Step 4, the staff observes the dirt content in the water discharged from the sewage hose. When there is no dirt in the water discharged from the hose, the staff stops injecting tap water into the sewage inlet, and the rubber sliding sealing plate automatically resets; return to step 2.

[0030] Preferably, the right joint is connected to the right lower groove through a connecting channel, and the left joint is connected to the left lower groove through a conducting channel; a plurality of restraint ropes are provided at the lower part of the box body, and the lower ends of the restraint ropes are connected to the counterweight block; step 1 is replaced by the following steps:

[0031] Sealing covers are placed on the left and right joints, and the air is kept in the lower cavity; the sewage discharge device is placed in the breeding pond, and each counterweight falls to the bottom of the breeding pond. The length of the restraining rope is adjusted to make the sewage discharge device stably suspended in the water below the oxygen generator.

[0033] The staff controls the water pump to slowly pump the water in the upper cavity out of the upper cavity; driven by the water flow and the action of gravity, the excrement and food residues of the fry enter the upper cavity through various waste inlets and waste switch conversion ports.

[0034] Therefore, the present invention has the following beneficial effects: it can automatically collect excrement and food residues of fry; when removing dirt, it will not affect the fry, and can meet the requirements of the breeding pond on the frequency of dirt cleaning, providing a reliable basis for improving the breeding rate of fry.
