[0019] The utility model is further described below with specific embodiments:

[0020] See also Figures 1 to 4 This embodiment provides a fish farming device that is convenient for collecting feces. The fish farming device includes a fish farming bucket 1 and a feces collecting barrel 2.

[0021] See also Figure 1 and Figure 3 The inner bottom of the fish farming barrel 1 presents a configuration of "high periphery and low center". For the convenience of description, this configuration is called a "central depressed configuration", and the lowest part at the center of this central depressed configuration is called a "central low point".

[0022] A funnel-shaped structure is provided at the central low point of the bottom of the inner side of the fish farming bucket 1, and the structure runs through the bottom of the fish farming bucket 1. That is, there is a hole at the central low point of the bottom of the inner side of the fish farming bucket 1, and a funnel-shaped inclined surface is provided around the hole. For the convenience of description, this structure is called a sedimentation funnel part 11.

[0023] A leak plate 12 is also provided for the sedimentation funnel 11, and the leak plate 12 is arranged at the sedimentation funnel 11 in the fish farming bucket 1 and covers the top of the sedimentation funnel 11. The leak plate 12 is used to prevent the fish in the fish farming bucket 1 from leaking from the sedimentation funnel.

[0024] A drainage pipe 4 is arranged below the bottom of the fish tank 1. The drainage pipe 4 has three pipe openings, one of which faces upward and is directly connected to the sedimentation funnel 11 arranged at the bottom of the fish tank 1, and the other two pipe openings face downward and are respectively provided with control valves.

[0025] In summary, the sewer pipe 4 is connected to the sedimentation funnel 11 provided at the bottom of the fish tank 1, and the sewer pipe 4 is provided with two valve-controlled pipe openings facing downward, namely, a feces discharge valve-controlled pipe opening 41 and a drainage valve-controlled pipe opening 42. The feces discharge valve-controlled pipe opening 41 is used to discharge the fish feces accumulated in the sedimentation funnel 11, and the drainage valve-controlled pipe opening 42 is used for drainage when changing water, and is directly connected to the sewer.

[0026] It should be noted that the valve-controlled pipe outlet mentioned above refers to a pipe outlet provided with a control valve.

[0027] See also Figure 2 The manure collecting barrel 2 is a relatively independent component, and the overall configuration of the manure collecting barrel 2 is: one end is thicker, the other end is thinner, and the two ends are smoothly transitioned. For the convenience of description, this configuration is called a "gradient diameter configuration".

[0028] The manure collecting barrel 2 is provided with an opening at both the thicker end and the thinner end, wherein the opening at the thicker end is called the water receiving port 21, and the opening at the thinner end is called the water filtering port 22. In addition, corresponding covers are provided for the water receiving port 21 and the water filtering port 22 to close the two openings, and the covers are connected to the openings by threads.

[0029] It should be noted that a fixed cloth cover 24 and a filter cloth 23 are also provided for the water filter port 22 of the manure collecting barrel 2. The fixed cloth cover 24 has the same basic configuration as the sealing cover, and can also be assembled on the water filter port 22 of the manure collecting barrel 2 by threaded connection. The difference is that the fixed cloth cover 24 is transparent and open, and its function is to fix the filter cloth 23 at the water filter port 22. When filtering treatment is required, the filter cloth 23 is wrapped at the water filter port 22, and then the fixed cloth cover 24 is assembled on the water filter port 22 through the filter cloth 23, so that the filter cloth 23 is fixed on the water filter port 22.

[0030] For the convenience of description, the thicker end of the feces collecting barrel 2 where the water inlet 21 is arranged is called the "water receiving end", and the thinner end of the feces collecting barrel 2 where the water filtering outlet 22 is arranged is called the "water filtering end".

[0031] See also Figure 1 A bracket 3 is provided on the side of the fish farming barrel 1. The configuration of the bracket 3 matches the manure collecting barrel 2. The function of the bracket 3 is to place the manure collecting barrel 2. At this time, the water filter port 22 of the manure collecting barrel 2 faces the lower inner side of the fish farming barrel 1.

[0032] See also Figure 4 The specific method of using the fish farming device of this embodiment is as follows:

[0033] Since the inner bottom of the fish barrel 1 is a centrally depressed configuration, and a sedimentation funnel 11 is provided at the central low point, such a configuration allows the fish feces in the fish barrel 1 to naturally settle and gather in the sedimentation funnel 11. When collecting feces in a planned manner, the water filter port 22 of the feces collecting cylinder 2 is first sealed with a cover, the cover of the water inlet 21 is opened, the feces collecting cylinder 2 is moved to the bottom of the fish barrel 1, and the water inlet 21 is aligned with the feces discharge valve control port 41 of the sewer pipe 4, and then the valve on the feces discharge valve control port 41 is opened, and the feces in the sedimentation funnel 11 is collected. After all the fish excrement enters the excrement collecting barrel 2, the valve is closed; then the cover of the water inlet 21 is closed, the cover of the water filter outlet 22 is removed and replaced with an assembly combination of the filter cloth 23 and the fixed cloth cover 24, and the excrement collecting barrel 2 is placed on the bracket 3 as a whole, with the water filter outlet 22 of the excrement collecting barrel 2 facing the lower inner side of the fish farming barrel 1, and the water in the excrement collecting barrel 2 flows into the fish farming barrel 1 through the filter cloth 23 at the water filter outlet 22, while the fish excrement cannot pass through the filter cloth 23 and is retained in the excrement collecting barrel 2, that is, the fish excrement is filtered out, thereby realizing the collection of the fish excrement.

[0034] In the fish farming device of this embodiment, a sedimentation funnel 11 is provided at the bottom of the fish farming barrel 1, and a drainage pipe 4 is connected to the sedimentation funnel 11, and the drainage pipe 4 is provided with a feces discharge valve control port 41. When collecting fish feces, the valve on the feces discharge valve control port 41 is opened, and after all the fish feces in the sedimentation funnel 11 enter the feces collecting barrel 2, the valve is closed. In this way, all the fish feces in the fish farming barrel 1 are collected in the feces collecting barrel 2. After the water is filtered out, the fish feces can be used for evaluation and analysis of apparent digestibility.

[0035] The fish farming device of this embodiment is used to farm fish, and the fish feces in the fish farming barrel 1 can be collected to the maximum extent, thereby providing complete and accurate fish feces data for the evaluation and analysis of the apparent digestibility, thereby improving the accuracy and reliability of the data analysis, and the operation process of collecting fish feces is very convenient, thereby reducing manpower and time costs and improving work efficiency; in the process of collecting fish feces, there is no need to use manual or mechanical means to directly collect fish feces from the water body, thereby reducing interference with the living environment of the fish and the pressure on the fish themselves.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
