Description

Technical Field

[0001] This utility model relates to the field of dredging aquaculture waters, and in particular to an automatic dredging device for aquaculture. Background Technology

[0002] In aquaculture, there are certain requirements regarding the thickness of silt in the ponds. Excessive silt reduces water volume, decreases the living space for fish, increases oxygen consumption, and makes fish more susceptible to diseases. Therefore, removing excess silt is a crucial technical step.

[0003] If the aquaculture pond is small, the drainage and dredging method can be used, that is, first drain the water from the pond to expose the silt, and then clean it. However, this method is not suitable for large-scale ecological aquaculture in fishponds. Therefore, dredging work needs to be carried out without draining the water and with minimal impact on the aquaculture. Based on this, the applicant proposes an automatic dredging device for aquaculture. Utility Model Content

[0004] To address the technical challenges of dredging ribbonfish during large-scale ecological aquaculture, this invention provides an automatic dredging device for aquaculture.

[0005] This utility model is achieved by the following technical solution: an automatic silt removal device for aquaculture, including a silt removal pump, a fixing plate fixedly connected to the bottom of the silt removal pump, and a fixture further mounted on the fixing plate:

[0006] A telescopic shaft is fixedly mounted on the fixed plate, and a mounting bracket is fixedly connected to the lower end of the telescopic shaft;

[0007] A sludge removal pipe is provided in the middle of the mounting frame, and the upper end of the sludge removal pipe is connected to the sludge removal pump;

[0008] A crushing assembly is movably mounted on the mounting bracket, and the crushing assembly includes a crushing blade disposed at the bottom of the sludge removal pipe.

[0009] With the above technical solution, in practical use, the fixing plate can be installed on a small boat, which then moves the entire equipment. The dredging pipe is lowered underwater via a telescopic shaft, ensuring its lower end contacts the silt. When the dredging pump is started, the silt is sucked into the dredging pipe and then discharged through the pump, completing the dredging process. While the dredging pump is operating, the crushing blades in the crushing assembly also rotate, breaking up any clumps of silt entering the dredging pipe and preventing silt from jamming the pump.

[0010] As a further improvement to the above solution, the telescopic shaft is vertically fixedly installed on the fixed plate, the lower end of the telescopic shaft passes through the fixed plate and is located below the fixed plate, and a fixed frame is fixedly connected to the outside of the telescopic shaft, and the fixed frame and the fixed plate are fixedly connected.

[0011] The above technical solution uses the extension of the telescopic shaft to move the entire mounting frame downwards and into the water, allowing the dredging pipe to contact the silt at the bottom of the water.

[0012] As a further improvement to the above solution, the mounting frame includes a mounting plate and a mounting cylinder, which are fixedly connected. The lower end of the telescopic shaft is fixedly connected to the mounting plate. A circular through hole is provided in the middle of the mounting cylinder. The sludge removal pipe is fixedly connected to the mounting frame through the circular through hole. The upper end of the sludge removal pipe is connected to the sludge removal pump through a connecting hose.

[0013] As a further improvement to the above solution, the crushing component includes:

[0014] An internal toothed ring, wherein a retaining ring is fixedly connected to the outer side wall of the internal toothed ring, and an annular groove is opened at the corresponding position on the inner side wall of the mounting cylinder, and the retaining ring is movably installed in the annular groove;

[0015] The crushing shaft is further fixedly connected to the inside of the mounting cylinder, and the crushing shaft and the mounting cylinder are rotatably connected. At the same time, the lower end of the crushing shaft extends out of the mounting cylinder, and the crushing blade is fixedly connected to the crushing shaft.

[0016] The gear is fixedly connected to the crushing shaft and is located inside the cage. The gear meshes with the internal gear ring.

[0017] As a further improvement to the above solution, the crushing component also includes a motor, which is fixedly mounted on the mounting cylinder, and the motor is connected to one of the gears.

[0018] With the above technical solution, the motor drives one of the gears to rotate, which in turn drives the gear ring to rotate, and thus also drives the remaining two gears to rotate. Therefore, the three crushing shafts will drive the crushing blades to rotate together.

[0019] As a further improvement to the above solution, an isolation net is fixedly connected to the bottom of the mounting cylinder and outside the dredging pipe, and a scraper is fixedly connected to the crushing shaft.

[0020] As a further improvement to the above solution, an outer protective frame is also fixedly connected to the outer wall of the mounting cylinder, and the outer protective frame is located outside the crushing blade.

[0021] Through the above technical solution, the isolation net can prevent leaves, garbage bags and other possible garbage from entering the dredging pump and clogging the pipes, thus damaging the dredging pump. At the same time, the scraper rotates with the crushing shaft to remove the garbage from the surface of the isolation net, preventing garbage from blocking the sludge and maintaining the dredging efficiency.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] This utility model uses a dredging pump in conjunction with a connecting hose and a dredging pipe to extract silt from the bottom of the water, thereby achieving the purpose of dredging. During the dredging process, the crushing blade can be controlled to rotate together with the crushing shaft to break up the clumps of silt, making it easy to discharge the silt through the dredging pipe. The isolation net can prevent garbage from entering the dredging pump pipeline, protecting the dredging pump. When the scraper rotates, it can remove garbage from the surface of the isolation net, preventing garbage from blocking the silt and maintaining dredging efficiency. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Please combine Figures 1-4This embodiment of an automatic sludge removal device for aquaculture includes a sludge removal pump 1 and a fixing plate 3. The sludge removal pump 1 is first fixedly installed on the fixing plate 3. In actual use, the fixing plate 3 can be connected to a small boat (not shown in the figure), and the entire device can be moved by the small boat to dredge the aquaculture area. The sludge removal pump 1 includes a sludge inlet and an outlet, with a connecting hose 2 connected to the inlet via a flange.

[0031] A telescopic shaft 4 is also fixedly connected to the fixed plate 3. The telescopic shaft 4 is installed vertically, and its lower end passes through the fixed plate 3 and is fixedly connected to the mounting bracket 6. Since the telescopic shaft 4 needs to be installed vertically, a fixing bracket 5 is also provided to maintain stability. The fixing bracket 5 is fixedly sleeved on the outside of the telescopic shaft 4, and the fixing bracket 5 is fixedly connected to the fixed plate 3.

[0032] The mounting bracket 6 includes a mounting plate 7 and a mounting cylinder 8, which are fixedly connected, and the lower end of the telescopic shaft 4 is fixedly connected to the mounting plate 7.

[0033] The mounting cylinder 8 has a through hole in the middle, through which a sludge removal pipe 9 is fixedly connected. The upper end of the sludge removal pipe 9 is connected to the connecting hose 2. When the sludge removal pump 1 starts working, a negative pressure is formed inside it. Under the action of external pressure, the sludge enters the sludge removal pipe 9, and then exits from the outlet end of the sludge removal pump 1 through the connecting hose 2. In actual use, the outlet end is also connected with a hose, and the discharged sludge accumulates on the ship, awaiting subsequent cleaning.

[0034] In addition to silt, the bottom of aquaculture areas may also contain other garbage, such as unrotted leaves or even plastic bags. To prevent this garbage from entering the dredging pump 1 and clogging the pipes, an isolation net 19 is fixedly connected to the bottom of the installation cylinder 8, i.e., the bottom inlet of the dredging pipe 9, to prevent the aforementioned garbage from entering the dredging pump 1 through the dredging pipe 9 and damaging the dredging pump 1.

[0035] In addition, the aquaculture area may contain clumps of silt that cannot be directly sucked in by the sludge removal pipe 9, so a crushing component 10 is also provided. Specifically, the crushing component 10 includes an internal gear ring 11 and a gear 16. First, a retaining ring 12 is fixedly connected to the outer wall of the internal gear ring 11. An annular groove 13 is opened at the corresponding position on the inner wall of the mounting cylinder 8, in which the retaining ring 12 is engaged in the annular groove 13. Therefore, at this time, the internal gear ring 11 can only rotate and cannot move its position.

[0036] For mounting gear 16, a retainer 15 is fixedly connected inside the mounting cylinder 8. A crushing shaft 14 is rotatably connected to the retainer 15 via a bearing, and the lower end of the crushing shaft 14 extends out of the mounting cylinder 8. Gear 16 is fixedly connected to the crushing shaft 14 and is located inside the retainer 15. Gear 16 also meshes with the internal gear ring 11. Three retainers 15, three crushing shafts 14, and three gears 16 are provided. Additionally, a crushing blade 17 is fixedly connected to the portion of the crushing shaft 14 extending out of the mounting cylinder 8.

[0037] To drive the crushing shaft 14 to rotate, a motor 18 is also provided. The motor 18 is fixedly mounted on the mounting cylinder 8, and the output shaft of the motor 18 is fixedly connected to one of the crushing shafts 14. Since it needs to operate underwater, an underwater motor 18 can be used, and proper sealing is required. When the motor 18 is started, the crushing shaft 14 connected to the output shaft of the motor 18 rotates. The crushing shaft 14 drives the gear 16 to rotate together, and the gear 16 drives the meshing internal gear ring 11 to rotate. At the same time, the internal gear ring 11 drives the other two sets of gears 16 and the crushing shaft 14 to rotate together. When the crushing blade 17 rotates, it can break up the clumps of silt, making it easier to discharge.

[0038] Additionally, as described above, an isolation net 19 is installed at the bottom of the mounting cylinder 8. A scraper 20 is also fixedly connected to the crushing shaft 14. The scraper 20 is close to the isolation net 19. If impurities (such as leaves or plastic bags) adhere to the isolation net 19, although these impurities are blocked by the isolation net 19 and will not enter the sludge pump 1, they will obstruct the sludge and reduce the sludge removal speed. Therefore, when the scraper 20 rotates together with the crushing shaft 14, it can remove the impurities and debris attached to it.

[0039] An outer protective frame 21 is welded and fixed to the outside of the mounting cylinder 8, and the outer protective frame 21 also protects the breaker blade 17 inside. When not in use, the outer protective frame 21 can contact the ground, supporting the dredging pipe 9, mounting frame 6, and other structures, preventing the breaker blade 17 from contacting the ground, and facilitating storage and transportation. When in use, the outer protective frame 21 also protects the breaker blade 17, especially when dredging near the shore, preventing the breaker blade 17 from contacting hard structures such as pond slopes. This protects the breaker blade 17.

[0040] The implementation process and principle of an automatic silt removal device for aquaculture in this application embodiment are as follows:

[0041] (a) Attach the fixing plate 3 to the small boat, and move the entire equipment within the aquaculture area using the small boat. Connect the dredging pump 1 and the dredging pipe 9 via the connecting hose 2. By controlling the extension of the telescopic shaft 4, the mounting frame 6 is submerged underwater and comes into contact with the silt on the bottom.

[0042] (II): The dredging pump 1 creates a negative pressure inside, drawing the sludge into the dredging pipe 9, and then discharges it from the outlet end of the dredging pump 1 through the connecting hose 2. The outlet end can also be connected with a hose to accumulate the discharged sludge on the ship for subsequent cleaning.

[0043] While the dredging pump 1 is operating, the motor drives one of the gears 16 to rotate, which, in conjunction with the internal gear ring 11, controls the rotation of the three crushing shafts 14. The crushing blades 17 rotate along with the crushing shafts 14, breaking up the clumps of sludge and facilitating its discharge through the dredging pipe 9. The isolation net 19 prevents debris such as leaves and plastic bags from entering the dredging pump 1's pipe, protecting the pump. Simultaneously, the scraper 20 rotates with the crushing shafts 14, removing debris from the surface of the isolation net 19 to prevent it from obstructing the sludge and maintain dredging efficiency.

[0044] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
