Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to a crab farming device. Background Technology

[0002] Large-scale aquaculture is already quite common in existing aquaculture, but due to the characteristics of crab farming, most crab farming is still in the traditional farming mode, resulting in high farming costs, small scale, and large labor input. Some farming bases are using crab farming tanks for large-scale factory farming.

[0003] For example, Chinese utility model patent CN209572876U discloses a crab farming device, including a main water inlet pipe, a main drain pipe, and multiple sets of farming boxes arranged between the main water inlet pipe and the main drain pipe. The farming box includes a box body arranged between the main water inlet pipe and the main drain pipe, and a farming plate arranged inside the box body. The device allows water to enter the farming box through the main water inlet pipe while draining water from the farming box through the main drain pipe, realizing rapid water exchange and cleaning of the farming box. However, uneaten food and feces left by the crabs tend to accumulate in the area under the farming plate, which is inconvenient to clean and affects the water quality of the farming box. Utility Model Content

[0004] The purpose of this invention is to provide a crab farming device to solve the problems mentioned in the background art.

[0005] The above-mentioned objective of this utility model is achieved through the following technical solution: a crab farming device, including an inlet pipe, an outlet pipe, and multiple farming boxes disposed between the inlet pipe and the outlet pipe. A partition plate is disposed near the bottom of each farming box, dividing the farming box into a farming chamber and a sludge accumulation chamber. The farming chamber and the sludge accumulation chamber are distributed vertically. Filter holes are disposed on the partition plate, and the farming chamber and the sludge accumulation chamber are connected through the filter holes. The inlet pipe is connected to the sludge accumulation chamber through a first connecting pipe, and the outlet pipe is connected to the sludge accumulation chamber through a second connecting pipe.

[0006] Preferably, the partition plate includes a high plate, a low plate, and an inclined plate connecting the high plate and the low plate, and the filter array is distributed on the low plate.

[0007] Preferably, a gap groove is formed between the end of the low-position plate and the inner wall of the breeding box.

[0008] Preferably, an overflow pipe is provided above the partition plate, and the breeding chamber is connected to the water outlet pipe through the overflow pipe.

[0009] Preferably, a filter screen is provided at the inlet end of the overflow pipe.

[0010] Preferably, both the first connecting pipe and the second connecting pipe are equipped with control valves.

[0011] Preferably, the upper end of the breeding box is provided with a cover plate, and the cover plate is provided with a feeding port.

[0012] Preferably, the breeding box is equipped with a movable box, the outer wall of which is fitted to the inner wall of the breeding box, and the partition is fixedly connected to the bottom of the movable box.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model divides the breeding box into a breeding chamber and a sludge accumulation chamber by setting a partition plate and filter holes, making it easier to collect sludge and achieving effective separation of breeding water and sludge. This not only keeps the breeding chamber clean, but also provides a healthier growth environment for crabs.

[0015] 2. The inlet pipe is directly connected to the sludge chamber, facilitating the introduction of fresh water for water quality renewal; while the outlet pipe also extends from the sludge chamber, allowing for more efficient removal of old water and waste. This design simplifies the water quality management process and improves management efficiency. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described in detail below with reference to the accompanying drawings.

[0022] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.

[0023] Example 1:

[0024] like Figure 1 and Figure 2 As shown, a crab farming device includes an inlet pipe 1, an outlet pipe 2, and multiple farming boxes 3 disposed between the inlet pipe 1 and the outlet pipe 2. The inlet pipe 1 and the farming boxes 3 are connected by a first connecting pipe 4, and the outlet pipe 2 and the farming boxes 3 are connected by a second connecting pipe 5. Both the first connecting pipe 4 and the second connecting pipe 5 are equipped with control valves 6, which are solenoid valves.

[0025] The upper end of the breeding box 3 is provided with a cover plate 9, which covers the upper end of the breeding box 3, and a feeding port 901 is provided on the cover plate 9.

[0026] A partition plate 7 is installed near the bottom of the breeding box 3. The partition plate 7 divides the breeding box 3 into a breeding chamber 301 and a sludge accumulation chamber 302. The breeding chamber 301 and the sludge accumulation chamber 302 are distributed vertically. The partition plate 7 is provided with filter holes 704, and the breeding chamber 301 and the sludge accumulation chamber 302 are connected through the filter holes 704.

[0027] The inlet pipe 1 is connected to the sludge chamber 302 via the first connecting pipe 4, and the outlet pipe 2 is connected to the sludge chamber 302 via the second connecting pipe 5.

[0028] The partition plate 7 includes a high plate 701, a low plate 703, and an inclined plate 702 connecting the high plate 701 and the low plate 703. The filter holes 704 are arrayed on the low plate 703.

[0029] A gap groove 11 is formed between the end of the low-level plate 703 and the inner wall of the breeding tank 3. The width of the gap groove 11 is larger than the aperture of the filter hole 704. When the breeding tank 3 discharges water, the water flows towards the outlet pipe 2, carrying the uneaten feed and feces on the partition plate 7 downward to the low-level plate 703. The feces then enter the sludge accumulation chamber 302 below through the filter hole 704 and the gap groove 11 on the low-level plate 703 and are discharged with the outlet pipe 2, preventing the uneaten feed and feces from accumulating in the breeding tank 3.

[0030] An overflow pipe 8 is installed above the partition plate 7. The breeding chamber 301 is connected to the water outlet pipe 2 through the overflow pipe 8. A filter screen 10 is installed at the inlet end of the overflow pipe 8. When the water level in the breeding tank 3 is higher than the overflow pipe 8, the excess water is discharged through the overflow pipe 8 to prevent the water level in the breeding tank 3 from being too high.

[0031] Example 2:

[0032] like Figure 3 and Figure 4 As shown, the difference from Embodiment 1 is that a movable box 12 is provided inside the breeding box 3. The outer wall of the movable box 12 is attached to the inner wall of the breeding box 3, and the partition plate 7 is fixedly connected to the bottom of the movable box 12. When it is necessary to remove all the crabs from the breeding box 1, the cover plate 9 is opened and the movable box 12 is lifted upwards. During the lifting process, the water in the movable box 12 is discharged into the breeding box 1 through the hole 704 and the gap groove 11.
