[0002] The land-based barrel farming model is an intensive farming model that builds farming facilities on land. The barrel farming pond has a conical bottom. Generally, a fish toilet and other pipes are installed in the middle of the fish pond for sewage discharge. The flow of water is used to gather waste in the center of the fish pond for easy discharge, which can reduce the accumulation of harmful components in the fish pond.

[0003] However, the initial investment of land-based drum farming is large. Not only does the infrastructure construction require a lot of money, but farming also requires a lot of production investment. It has very high requirements for water quality. It is not easy for multiple indicators such as ammonia nitrogen and salt to meet the index standards, pH value, oxygen content, etc. Oxygen content is very critical. Feces residue will increase ammonia nitrogen and salt. Feces will absorb a lot of oxygen during decomposition, and better oxygenation and defecation are needed. However, the oxygenation system that needs to be installed in the existing system is expensive, and the high operating cost affects the farming efficiency, which is not suitable for small-scale farming. Therefore, the utility model is proposed. Utility Model Content

The blower 2 in this embodiment adopts a Roots blower. The other end of the U-shaped tube 1 is provided with an exhaust pipe 4, and the exhaust pipe 4 is provided with a plurality of exhaust holes 404. The exhaust pipe 4 extends into the interior of the drum breeding pond.

[0029] The exhaust pipe 4 in this embodiment is a retractable pipe body, and the length of the exhaust pipe 4 extending into the drum aquaculture pond can be adjusted according to the water depth inside the aquaculture pond, which is more convenient to use. Figure 2 and Figure 3 The exhaust pipe 4 includes three tubes with gradually decreasing diameters from top to bottom, namely, a first tube 401, a second tube 402 and a third tube 403. The second tube 402 is slidably connected to the inside of the first tube 401, and the third tube 403 is slidably connected to the inside of the second tube 402. The inner walls of the first tube 401 and the second tube 402 are symmetrically provided with slide grooves 405 (the length of the slide grooves is less than the length of the corresponding tubes and is located in the middle of the tubes). The outer walls of the second tube 402 and the outer walls of the third tube 403 are fixed with sliders 406, and the sliders 406 slide up and down along the slide grooves 405. The first tube 401, the second tube 402 and the third tube 403 are provided with a plurality of exhaust holes 404 arranged vertically, and the exhaust holes 404 on the second tube 402 and the third tube 403 correspond to the exhaust holes 404 on the first tube 401.

Two fixing plates 7 are symmetrically fixed to the outer wall of one end of the U-shaped tube 1 close to the exhaust pipe 4. Figure 4As shown, each fixing plate 7 is provided with two fixing holes 701, and the end of the limiting rope 6 away from the limiting plate 5 passes through the two limiting holes 701 in turn and is tied to the fixing plate 7. The limiting plate 5 needs to have a certain weight to be able to drive the third tube body 403 and the second tube body 402 to move downward in the water, and a stainless steel plate or metal block with a certain thickness can be used. When in use, the limiting rope 6 is untied from the fixing plate 7, and the third tube body 403 slides downward under the action of the limiting plate 5, and drives the second tube body 402 to slide downward. After reaching the required length, the limiting rope 6 is tied to the fixing plate 7.

[0031] For ease of use, marks can be set on the limit rope 6 at certain intervals as needed. The marks can be made of ropes of different colors wrapped around the limit rope 6. When in use, the exhaust pipe 4 can be directly extended to the required length according to the marks.

The second mounting plate 9 is provided with a threaded hole, and a locking bolt 10 is provided in the threaded hole. An anti-skid rubber plate 11 is fixed to one end of the locking bolt 10. When in use, the first mounting plate 8 is placed on the side wall of the drum culture pool, so that the two second mounting plates 9 are respectively on the inner and outer sides of the side wall of the culture pool, and the locking bolt 10 is tightened to make the anti-skid rubber plate 11 fit tightly with the side wall of the culture pool. The first mounting plate 8, the second mounting plate 9, the locking bolt 10 and the anti-skid rubber plate 11 can increase the stability of the device.

[0033] An air filter 12 is installed on the connecting pipe 3 to filter the gas entering the culture pond and remove impurities such as dust. Figure 5 As shown, the air filter device 12 includes a box body 1201 and a filter screen 1202. Both ends of the box body 1201 are provided with through holes 1204, which are connected to the connecting pipe 3. Two opposite side walls inside the box body 1201 are provided with U-shaped slide rails. The outer frame of the filter screen 1202 is fixed with a slider, and the slider slides along the U-shaped slide rail. The filter screen 1202 can be a conventional air filter screen in this field. The side wall of the box body 1201 is rotatably connected with a box door 1203, and a lock is also provided between the box door 1203 and the box body 1201. Open the box door 1203, pull the filter screen 1202 outward, so that the slider is separated from the U-shaped slide rail, and remove the filter screen 1202, so that the filter screen 1202 can be cleaned or replaced.
