Description

Technical Field

[0001] This utility model relates to the field of pond silt removal technology, and in particular to a silt removal device for crab farming ponds. Background Technology

[0002] During the crab farming process, the crabs' feces, excrement, uneaten feed, and dead plankton accumulate continuously. At the same time, surface impact debris and silt washed by rainwater also continuously settle at the bottom of the pond. These substances are fermented and decomposed by microorganisms, mixing with the moist soil on the surface of the pond bottom to gradually form a certain thickness of silt. The silt contains a large amount of organic matter and nutrients, which consume a lot of oxygen during decomposition, leading to oxygen deficiency in the pond water. It also produces toxic and harmful substances such as hydrogen sulfide and ammonia nitrogen, which deteriorates the water quality and affects the growth environment of the crabs.

[0003] Most existing mixing components are fixed with lock nuts. However, if the lock nuts are tightened or loosened improperly, excessive force is applied, unsuitable tools are used, or impurities are present in the threads, the threads can be easily damaged. In addition, repeated tightening and loosening over a long period of time will gradually wear down the threads, reduce the thread fit accuracy and connection strength, and may eventually cause the lock nuts to fail to effectively fix the mixing components.

[0004] Therefore, there is an urgent need to provide a dredging device for crab farming ponds to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a dredging device for crab farming ponds.

[0006] To solve the above-mentioned technical problems, the present invention provides a dredging device for crab farming ponds, comprising a water pump body, an installation ring fixedly connected to the bottom of the water pump body, a drainage box fixedly connected to the bottom of the installation ring, a linkage disc installed at the output end of the water pump body, an impeller fixedly connected to the bottom of the linkage disc, a stirring assembly installed on the impeller, a support member fixedly connected to the bottom of the drainage box, and multiple reinforcing blocks fixedly connected to the outer wall of the support member.

[0007] The present invention is further configured such that: the stirring assembly includes a linkage rod fixedly connected to the top of the inner wall of the impeller, the bottom of the outer wall of the linkage rod is provided with a thread, a connecting rod is slidably connected to the inner wall of the linkage rod, a fixing member is threadedly connected to the outer wall of the linkage rod, a plurality of first racks are fixedly connected to the bottom of the inner wall of the fixing member, a plurality of second racks are fixedly connected to the outer wall of the connecting rod, a plurality of cutting blades are fixedly connected to the bottom of the outer wall of the connecting rod, and a reinforcing block is fixedly connected between the outer walls of every two cutting blades.

[0008] With the above technical solution, during installation, firstly, the connecting rod is slidably connected into the inner wall of the linkage rod. Then, the fixing part is slid upward along the outer wall of the connecting rod until the first rack and the second rack mesh. Then, the fixing part is threadedly connected to the outer wall of the linkage rod through the threaded line. At this time, the top of the connecting rod will be tightly fitted with the top of the inner wall of the linkage rod. During disassembly, first rotate the fixing part to make it detach from the outer wall of the linkage rod. Then, simply slide the connecting rod out of the inner wall of the linkage rod.

[0009] The present invention is further configured such that: the top of the inner wall of the fixing member is provided with an internal thread adapted to the thread line, and the fixing member is threadedly connected to the outer wall of the linkage rod through the internal thread.

[0010] The above technical solution can firmly connect the fixing component and the linkage rod together to form a stable structure, ensuring that the various parts of the stirring component will not easily undergo relative displacement during equipment operation, thus guaranteeing the stability of the entire system.

[0011] The present invention is further configured such that the first rack and the second rack are staggered, and all of the first racks mesh with the second rack.

[0012] Through the above technical solution, when the first and second racks mesh, they not only transmit power, but also restrict each other's lateral and longitudinal movement to a certain extent, making the structure of the entire stirring assembly more stable, reducing the relative shaking and displacement between components, improving the stability and reliability of the structure, and helping to extend the service life of the stirring assembly.

[0013] The present invention is further configured such that: all of the plurality of cutting blades are located on the same plane, and every two cutting blades are arranged at a 60° angle.

[0014] The above technical solution ensures that all cutting blades act on the material simultaneously during cutting, making the cutting action more coordinated and unified. Furthermore, the 60° angle setting allows the cutting blades to cut the material sequentially during rotation, forming a continuous cutting process, reducing the time the material spends in the cutting area, and improving cutting efficiency.

[0015] The present invention is further configured such that the outer wall of the impeller is tightly fitted with the inner wall of the drainage tank, and two sludge inlets are provided at the bottom of the impeller.

[0016] The above technical solution enables the impeller to more effectively drive the liquid flow when rotating, reducing backflow and turbulence around the impeller. The liquid can pass through the impeller more smoothly and be transported to the outlet of the drainage box, thereby improving the drainage efficiency of the entire drainage system.

[0017] The present invention is further configured such that multiple bolts are threadedly connected between the mounting ring and the drainage box and between the support member and the drainage box.

[0018] The above technical solution uses bolts as universal standard parts, which can be quickly replaced when damaged, without the need for customized special parts, thus reducing maintenance costs. At the same time, the modular design avoids the problem of the entire equipment being scrapped due to damage to the mounting ring, drainage box, support components and drainage box.

[0019] The beneficial effects of this utility model are as follows: 1. By setting up a mixing component, this utility model eliminates the need to spend a lot of time disassembling complex fixing devices when the mixing equipment is damaged during river repair and dredging, thus greatly shortening the repair time and improving the overall work efficiency. 2. By setting up support components and reinforcing blocks, this utility model can provide reliable support for each component of the dredging device, ensuring that the device maintains a stable posture during operation and preventing shaking, tilting or even collapse due to external forces or its own vibration, thus ensuring the normal progress of dredging work.

The connecting rod 603 has multiple cutting blades 607 fixedly connected to its outer bottom wall. A reinforcing block 608 is fixedly connected between the outer walls of every two cutting blades 607. During installation, the connecting rod 603 is first slidably connected into the inner wall of the linkage rod 601. Then, the fixing member 604 is slid upwards along the outer wall of the connecting rod 603 until the first rack 605 meshes with the second rack 606. Finally, the fixing member 604 is threaded onto the outer wall of the linkage rod 601 via the threaded wire 602. At this point, the top of the connecting rod 603 will be tightly fitted against the top of the inner wall of the linkage rod 601. During disassembly, the fixing member 604 is first rotated to disengage from the outer wall of the linkage rod 601. Then, simply slide the connecting rod 603 out of the inner wall of the linkage rod 601. The top of the inner wall of the fixing member 604 is provided with an internal thread that matches the thread line 602. The fixing member 604 is connected to the outer wall of the linkage rod 601 through the internal thread. This can firmly connect the fixing member 604 and the linkage rod 601 together to form a stable structure, ensuring that the various parts of the stirring assembly 6 will not easily undergo relative displacement during equipment operation, thus ensuring the stability of the entire system. The first rack 605 and the second rack 606 are staggered, and multiple first racks 605 mesh with the second rack 606. When the first rack 605 and the second rack 606 mesh, they not only transmit power but also... To a certain extent, the lateral and longitudinal movement of each other is restricted, making the structure of the entire mixing assembly 6 more stable, reducing the relative shaking and displacement between components, improving the stability and reliability of the structure, and helping to extend the service life of the mixing assembly 6. Multiple cutting blades 607 are all on the same plane, and every two cutting blades 607 are set at a 60° angle; this ensures that when cutting materials, all cutting blades 607 can act on the materials simultaneously, making the cutting action more coordinated and unified. In addition, the 60° angle setting allows the cutting blades 607 to cut the materials sequentially during rotation, forming a continuous cutting process, reducing the residence time of materials in the cutting area, and improving cutting efficiency. like Figure 1 , Figure 2 and Figure 3As shown, a support member 7 is fixedly connected to the bottom of the drainage tank 3, and multiple reinforcing blocks 8 are fixedly connected to the outer wall of the support member 7. The outer wall of the impeller 5 is tightly fitted to the inner wall of the drainage tank 3, and two sludge inlets are provided at the bottom of the impeller 5. This allows the impeller 5 to more effectively push the liquid flow when rotating, reducing backflow and turbulence around the impeller 5. The liquid can pass through the impeller 5 more smoothly and be transported to the outlet of the drainage tank 3, thereby improving the drainage efficiency of the entire drainage system. Multiple bolts are threadedly connected between the mounting ring 2 and the drainage tank 3, and between the support member 7 and the drainage tank 3. The bolts are general standard parts, which can be quickly replaced after damage without the need for customized special parts, reducing maintenance costs. At the same time, the modular design avoids the problem of the entire equipment being scrapped due to damage to the mounting ring 2, drainage tank 3, support member 7, and drainage tank 3.

Then, the fixing member 604 is threaded to the outer wall of the linkage rod 601 through the thread 602. At this time, the top of the connecting rod 603 will be tightly fitted with the top of the inner wall of the linkage rod 601. During disassembly, first rotate the fixing member 604 to disengage it from the outer wall of the linkage rod 601. Then, simply slide the connecting rod 603 out of the inner wall of the linkage rod 601.
