Description

Technical Field

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

[0002] Crab ponds are aquatic environmental facilities specifically designed, constructed, and managed for the artificial breeding of economic crab species such as river crabs, mud crabs, and swimming crabs. Their core function is to achieve high-density and sustainable crab production by simulating or optimizing the natural habitat conditions of crabs.

[0003] Traditional crab pond dredging relies on manual labor, which requires stopping the water supply and emptying the pond. Operators must manually remove the silt in a small, damp environment, and it is difficult to thoroughly clean the hardened silt at the bottom of the pond. This method is labor-intensive and inefficient. Utility Model Content

[0004] To address the technical problems of traditional crab pond dredging relying on manual labor, which makes it difficult to thoroughly clean the silt deposited on the pond bottom, and is also labor-intensive and inefficient, this utility model provides an automatic crab pond dredging device.

[0005] This utility model is achieved using the following technical solution: a recycling box for recovering sludge, wherein a screening frame is provided inside the recycling box, and guide rods are fixedly installed on both sides of the screening frame, with both guide rods sliding through the recycling box; an installation box, which is fixedly installed on the top of the recycling box, and a sludge pump is fixedly installed inside the installation box, with a retractable hose fixedly connected to the inlet end of the sludge pump, a horizontal pipe provided on the retractable hose, and multiple suction pipes provided on the horizontal pipe, and a sludge discharge pipe fixedly connected to the outlet end of the sludge pump, the outlet end of the sludge discharge pipe extending into the recycling box; a crushing mechanism, which is provided on the recycling box, for crushing the sludge that has hardened at the bottom of the pool; and a screening mechanism, which is provided on the recycling box, for screening stones and branches in the sludge.

[0006] Through the above technical solution, the recycling bin, as the main container of the entire sludge recycling and treatment system, provides a closed and suitable operating space for subsequent processing steps such as sludge collection and screening. The screening frame is the component that carries the sludge during the screening process. Under the action of the screening mechanism, the sludge is separated from impurities such as stones and branches. The sludge pump, as the power source of the entire sludge recycling system, uses its strong suction to draw the sludge from the bottom of the crab pond into the suction pipe, and then transports it to the recycling bin through the extendable hose and discharge pipe, realizing automatic sludge recycling. This greatly improves the efficiency of sludge recycling, reduces the intensity of manual labor, and the suction power can be adjusted according to actual needs to ensure the smooth operation of sludge recycling. The discharge pipe removes the sludge... The sludge discharged by the pump is guided to the recycling tank, realizing the transportation process of sludge from the crab pond to the recycling tank. The crushing mechanism can crush the compacted sludge at the bottom of the pond during the dredging process, breaking down the originally tightly bound and difficult-to-handle compacted sludge into loose small particles, making the sludge structure looser and facilitating subsequent sludge processing. The screening mechanism can screen the crushed sludge to separate impurities such as stones and branches, achieving complete separation of sludge and impurities, improving the quality of the recycled sludge. The sludge after removing impurities can be better applied to other fields, such as as fertilizer and soil conditioner, realizing the resource utilization of sludge, while reducing the damage that impurities may cause to subsequent processing equipment and reducing equipment maintenance costs.

[0007] As a further improvement to the above solution, the crushing mechanism includes a mounting frame, a rotating motor, a rotating rod, and multiple crushing blades. The mounting frame is installed on one side of the recycling box, the rotating motor is fixedly installed on the mounting frame, the rotating rod is rotatably installed on the mounting frame and one end is fixed to the output shaft of the rotating motor, and multiple crushing blades are all located on the rotating rod.

[0008] Through the above technical solution, the mounting frame serves as the installation foundation and support structure for other components of the crushing mechanism, providing a stable installation position for the rotating motor, rotating rod, etc. The rotating motor, as the power source of the crushing mechanism, provides power for the rotation of the rotating rod. Through its own rotation, it drives the rotating rod to rotate, thereby causing the crushing blades mounted on it to generate high-speed rotational motion, realizing the function of crushing sludge. Multiple crushing blades work together, greatly increasing the contact area and force with the sludge, which can quickly and effectively crush plated sludge and facilitate the sludge to be sucked into the recycling bin.

[0009] As a further improvement to the above scheme, the screening mechanism includes a reciprocating motor, a cam, a wheel, and a return spring. The reciprocating motor is fixedly installed on one side of the recycling box, the cam is rotatably installed on one side of the recycling box and fixed to the output shaft of the reciprocating motor, the wheel is rotatably installed on one end of the guide rod and contacts the cam, and the return spring is sleeved on the outside of the guide rod and its two ends are fixed to the recycling box and the screening frame, respectively.

[0010] Through the above technical solution, the reciprocating motor serves as the power source for the screening mechanism, providing driving force for the rotation of the cam. Through the rotation of its own output shaft, it drives the cam fixed to it to perform circular motion, thereby converting the motor's rotational motion into the specific motion required by subsequent components, driving the entire screening mechanism to operate. A wheel is installed at one end of the guide rod and contacts the cam, playing a role in rolling friction and motion transmission. When the cam rotates, the wheel rolls under the push of the cam profile, converting the cam's rotational motion into the linear motion of the guide rod, while reducing frictional resistance between the wheel and the cam, reducing energy loss and component wear. A return spring is sleeved on the outside of the guide rod, with both ends fixed to the recovery box and the screening frame respectively, mainly playing a role in return and buffering. When the cam pushes the wheel and guide rod to move the screening frame to one side, the return spring is compressed and stores elastic potential energy. When the cam rotates through a specific angle, the return spring releases the elastic potential energy, pushing the screening frame to move in the opposite direction, realizing the reciprocating motion of the screening frame. Simultaneously, the return spring can also buffer the impact force generated during screening, protecting the various components of the equipment from damage.

[0011] As a further improvement to the above solution, a hydraulic rod is fixedly installed on one side of the recycling bin, and a bracket is fixedly installed on the output rod of the hydraulic rod. The bracket is fixed to the horizontal tube and the mounting bracket respectively.

[0012] Through the above technical solution, the hydraulic rod, as a power drive component, provides power for the lifting and lowering of the horizontal pipe and the mounting frame. Through the extension and retraction of its output rod, it drives the fixed bracket to move up and down, thereby realizing the vertical position adjustment of the horizontal pipe and the mounting frame. In the process of crab pond sludge recycling, the sludge depth in different areas may vary. The hydraulic rod can flexibly adjust the height of the horizontal pipe and the mounting frame according to actual needs, so that the suction pipe and the crushing blade can accurately penetrate into the sludge layer at different depths.

[0013] As a further improvement to the above solution, multiple wheel frames are fixedly installed at the bottom of the recycling bin, and each wheel frame is equipped with a rotating caster.

[0014] Through the above technical solution, the combination of multiple wheel frames and mobile wheels gives the recycling box mobility, enabling the entire sludge recycling and treatment equipment to be easily transferred between different crab ponds and different work sites without relying on large lifting equipment or complicated handling processes, which greatly facilitates the use of the equipment in different aquaculture areas.

[0015] As a further improvement to the above solution, a mounting plate is fixedly installed at the bottom of the recycling bin, and a drive motor is fixedly installed on the mounting plate. The output shaft of the drive motor and the moving wheel are both equipped with sprockets, and a chain is fitted on the two sprockets, with the sprockets and the chain meshing together.

[0016] Through the above technical solution, the mounting plate serves as the mounting carrier for the drive motor, providing a stable fixed position for the drive motor. The drive motor, as the power source for the moving wheels, provides driving force for the rotation of the moving wheels. Through the rotation of its output shaft, the power is transmitted to the sprocket connected to it, and then the moving wheels are driven to rotate through the chain, realizing the automatic movement of the equipment. The application of the drive motor frees the equipment from the limitations of manual pushing and enables it to automatically move forward, backward, or turn according to the preset program or the operator's instructions, greatly improving the ease of operation and automation of the equipment and reducing the intensity of manual labor.

[0017] As a further improvement to the above solution, a support rod is slidably installed on one side of the recycling bin, and the support rod is fixed to the bracket.

[0018] Through the above technical solution, the support rod that is slidably installed on one side of the recycling box is fixedly connected to the bracket, providing additional support for the bracket and the connected horizontal pipe (driving the sludge suction pipe) and mounting frame (driving the crushing mechanism). When the hydraulic rod drives the bracket to rise and fall, the support rod slides synchronously along the recycling box, which plays the role of guiding the movement trajectory and ensuring that the bracket can rise and fall smoothly along the predetermined vertical direction, avoiding deviation or tilting.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention combines automatic movement and automatic dredging to achieve more efficient and comprehensive dredging operations. It can crush the crusted sludge at the bottom of the pond before dredging and can screen out stones and branches in the sludge for subsequent processing or utilization. It can adjust the height of the suction pipe in real time to accurately match different sludge layer thicknesses, avoid over-cleaning or residue, and improve the sludge recovery rate. It provides a set of efficient, intelligent and sustainable sludge recycling solutions for crab pond aquaculture. Attached Figure Description

The mounting frame 10 is located on one side of the recycling box 1. The rotating motor 11 is fixedly mounted on the mounting frame 10. The rotating rod 12 is rotatably mounted on the mounting frame 10 and one end is fixed to the output shaft of the rotating motor 11.

The cam 15 is rotatably installed on one side of the recycling box 1 and fixed to the output shaft of the reciprocating motor 14. The wheel 16 is rotatably installed on one end of the guide rod 3 and contacts the cam 15. The return spring 17 is sleeved on the guide rod 3 and its two ends are fixed to the recycling box 1 and the screening frame 2, respectively.

[0033] A hydraulic rod 18 is fixedly installed on one side of the recycling bin 1, and a bracket 19 is fixedly installed on the output rod of the hydraulic rod 18. The bracket 19 is fixed to the horizontal tube 7 and the mounting bracket 10 respectively.

[0034] The bottom of the recycling bin 1 is fixedly equipped with multiple wheel frames, and each of the multiple wheel frames is rotatably equipped with a movable wheel 20.

[0035] The bottom of the recycling bin 1 is fixedly installed with an installation plate 21, and a drive motor 22 is fixedly installed on the installation plate 21. The output shaft of the drive motor 22 and the moving wheel 20 are both provided with sprockets 23. A chain 24 is sleeved on the two sprockets 23, and the sprockets 23 and the chain 24 mesh with each other.

[0036] A support rod 25 is slidably installed on one side of the recycling bin 1, and the support rod 25 is fixed to the bracket 19.

[0037] The implementation principle of an automatic silt removal device for crab ponds in this application embodiment is as follows:

[0038] Before use, move the device to the edge of the crab pond that needs to be cleaned, start the drive motor 22, and the output shaft of the drive motor 22 drives the sprocket 23 to rotate. When the sprocket 23 rotates, it will continuously mesh with the chain 24, thereby driving the sprocket 23 on the moving wheel 20 to rotate, so that the moving wheel 20 can be rotated automatically. When it moves to the designated position, start the hydraulic rod 18, and the output rod of the hydraulic rod 18 extends, driving the horizontal tube 7 and the mounting bracket 10 to move to the position of the silt.

[0039] When in use, start the sludge pump 5. The sludge pump 5 sucks up the sludge from the bottom of the crab pond through the suction pipe 8. The sludge enters the recycling box 1 through the telescopic hose 6 and the discharge pipe 9. During this process, if the sludge at the bottom of the pond is hardened, start the rotating motor 11. The rotating motor 11 drives the rotating rod 12 to rotate. The multiple crushing blades 13 on the rotating rod 12 rotate continuously to crush the hardened sludge and loosen it so that it can be sucked in by the sludge pump 5.

[0040] When the sludge is sucked into the screening frame 2 inside the recycling bin 1, the screening mechanism screens the crushed sludge. The reciprocating motor 14 is started, and the reciprocating motor 14 drives the cam 15 to rotate. When the cam 15 rotates, the wheel 16 rolls under the push of the cam 15 profile, converting the rotational motion of the cam 15 into the linear motion of the guide rod 3. Depending on the different contact surfaces between the cam 15 and the wheel 16, the screening frame 2 can be driven to move left and right continuously, thereby separating impurities such as stones and branches from the sludge. The clean sludge remains in the recycling bin 1 for subsequent processing or utilization.
