Description

Technical Field

[0001] This utility model belongs to the field of dredging devices, specifically a dredging device for rice-fish farming. Background Technology

[0002] Rice-fish farming, as a highly efficient and ecological agricultural model, combines the advantages of both rice cultivation and aquaculture, improving land use efficiency and promoting ecological balance. However, during the rice-fish farming process, the accumulation of organic matter from rice growth and fish farming, as well as potential sediment deposition, easily leads to the formation of a silt layer at the bottom of the paddy field. This not only affects the growth of rice roots and nutrient absorption but may also adversely impact the fish's living environment. Therefore, regular silt removal is a crucial aspect of rice-fish farming management.

[0003] In existing technologies, silt is manually pushed with tools and then pumped out and cleaned using a sludge pump. This is not only time-consuming and labor-intensive, but also very troublesome for the planting area on top when cleaning the silt with tools. Therefore, this solution is designed with an intelligent control device for cleaning silt, which makes silt cleaning more convenient. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a dredging device for rice-fish farming, which solves the problem in the prior art where manual tools are used to push the silt, followed by a dredging pump to extract and clean it. This is not only time-consuming and labor-intensive, but also causes great trouble in the planting area at the top when cleaning the silt with tools.

[0005] A dredging device for rice-fish farming includes a planting pond and a planting board. The planting board is planted on the surface of the planting pond, and a partition is provided at the bottom of the planting pond. A water injection pipe is provided in the space between the partition and the water injection pipe. A high-pressure nozzle is installed on the water injection pipe and is located on the surface of the partition. Four sets of augers are installed inside the planting pond. A pulley is installed at one end of each of the four sets of augers. The pulleys are connected by belts, and a motor is installed on the middle pulley.

[0006] Preferably, one side of the planting pool is provided as an inclined plate, and the head of the inclined plate is provided with a groove, and a sludge removal pump is placed inside the groove.

[0007] Preferably, a pipe is provided on the planting pool and at the top of the inclined plate, and a water spray nozzle is installed on the pipe.

[0008] Preferably, the water spray nozzle is positioned directly opposite the top of the inclined plate.

[0009] Preferably, the dredging pump is equipped with a delivery pipe, which is connected to the sludge storage tank.

[0010] Preferably, a filter plate is provided at the bottom of the sludge storage tank, with the bottom of the filter plate facing the ground.

[0011] Compared with the prior art, this utility model has the following beneficial effects: By starting the motor, the motor drives the auger to rotate, which in turn moves the sludge at the bottom of the planting pool. This allows the auger to transport the sludge to the inclined plate, and the sludge is continuously transported to the sludge removal pump by the water spray nozzle. The sludge removal pump is then started, and the sludge is transported to the sludge storage tank through the conveying pipe. The sludge storage tank stores the sludge. This utility model can intelligently extract and store the sludge accumulated at the bottom of the rice paddy, thus avoiding the situation where the sludge gradually accumulates at the bottom of the rice paddy planting device and is difficult to clean.

[0016] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0017] like Figure 1-3 As shown, this utility model provides a dredging device for rice-fish farming, including a planting pond 1 and a planting board 2. The planting board 2 is planted on the surface of the planting pond 1. A partition 3 is provided at the bottom of the planting pond 1. A water injection pipe 4 is provided in the space between the partition 3. A high-pressure nozzle 5 is installed on the water injection pipe 4. The high-pressure nozzle 5 is located on the surface of the partition 3. The high-pressure nozzle 5 can wash out the silt deposited at the bottom of the planting pond 1, which facilitates the transportation of silt by four sets of augers 6. Four sets of augers 6 are installed inside the planting pond 1. A pulley 7 is installed at one end of the four sets of augers 6. The pulleys 7 are connected to each other by a belt 8. A motor 9 is installed on the middle pulley 7, which can drive the four sets of augers 6 to rotate.

[0018] One side of the planting pond 1 is set as an inclined plate, and the head of the inclined plate is provided with a groove. A sludge pump 12 is placed inside the groove. The sludge pump 12 is set at the lowest position, so that the sludge pump 12 can continuously clean the sludge and transport all the sludge in the planting pond 1 to the sludge pump 12.

[0019] A pipe 10 is installed on the planting pool 1 and at the top of the inclined plate. A water spray nozzle 11 is installed on the pipe 10. The water spray nozzle 11 is directly facing the top of the inclined plate. The water spray nozzle 11 can continuously flush the sludge, making the sludge pump 12 more efficient in pumping out the sludge.

[0020] The dredging pump 12 is equipped with a conveying pipe 13, which is connected to the sludge storage tank 14. The dredging pump 12 can convey sludge into the sludge storage tank 14 through the conveying pipe 13.

[0021] A filter plate 15 is provided at the bottom of the sludge storage tank 14. The bottom of the filter plate 15 faces the ground. The sludge can be filtered through the filter plate 15, so that the sludge accumulates inside the sludge storage tank 14, which is convenient for cleaning the sludge inside the sludge storage tank 14 later.

[0022] Working principle: When the sludge accumulated at the bottom of the planting pond 1 needs to be cleaned, the motor 9 is started. The motor 9 drives the four screw conveyors 6 to rotate, and at the same time, water is injected into the pipe 10 and the water injection pipe 4, so that the high-pressure nozzle 5 and the water spray nozzle 11 continuously impact the sludge until the sludge is transported to the inclined plate and continuously transported to the sludge cleaning pump 12. The sludge is then pumped by the sludge cleaning pump 12 to the sludge storage tank 14. The filter plate 15 filters the sludge, allowing water to permeate to the bottom. The filter plate 15 is filled with the remaining sludge after filtration, and then the sludge can be cleaned.

[0023] The embodiments of this utility model are given for the purpose of illustration and description. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
