Especially for strongly adhering substances, the rotary motion can provide stronger mechanical force, improving the dredging efficiency. The stainless steel material has good corrosion resistance and wear resistance, which can maintain the sharpness and surface smoothness of the dredging piece for a long time, prolonging the service life. The aperture of the dredging piece is matched with the aperture of the nozzle, ensuring that the dredging piece can smoothly enter the nozzle hole without damaging the nozzle hole. The combination of the telescopic cylinder and the rotary motor realizes semi-automatic dredging process. The operator only needs to place the nozzle on the nozzle carrier seat and start the equipment to automatically complete the dredging, reducing manual intervention and improving work efficiency. The telescopic cylinder and the rotary motor can be operated through a simple control panel or button, which is easy to operate and easy to use.

[0009] Further, the telescopic end of the telescopic cylinder I is connected to the rotary motor through bolts, the power output end of the rotary motor is welded with a nut, and the tail end of the dredging piece is provided with a thread matched with the nut of the power output end.

The power output end of the rotary motor is connected to the dredging piece through a welded nut, ensuring stable power transmission and making the dredging piece more stable during rotation, improving the dredging effect. Through thread connection, different aperture dredging pieces can be easily replaced to adapt to different specifications of nozzles, enhancing the versatility and flexibility of the device. If it is necessary to adjust the length or shape of the dredging piece, different dredging pieces can be replaced to achieve the adjustment without major changes to the entire device.

[0013] Further, the nozzle carrier seat comprises a nozzle positioning hole and a residue discharge hole, the nozzle positioning hole is vertically arranged at the central position of the nozzle carrier seat, and the residue discharge hole is horizontally arranged at the bottom of the nozzle carrier seat and communicates with the nozzle positioning hole.
[0014] By adopting the above technical scheme, the nozzle positioning hole is vertically arranged at the central position of the nozzle bearing seat, ensuring that the nozzle can be fixed vertically and stably on the bearing seat. This not only facilitates the installation and disassembly of the nozzle, but also ensures the stability of the nozzle during the dredging and cleaning process, avoiding poor dredging and cleaning effect caused by the inclination or loosening of the nozzle.

Once a component fails, it can be quickly diagnosed and handled through the power supply device, reducing downtime.
[0017] Further, the pump machine is connected with an external water supply device.
[0018] By adopting the above technical solution, the pump, connected to an external water supply device, can ensure a continuous and stable water supply, avoiding interruptions caused by insufficient internal water storage, thus improving the continuity and efficiency of cleaning. The external water supply device typically has a large water storage capacity and high water pressure, providing a large flow of cleaning fluid to ensure the efficiency and thoroughness of the cleaning process. The external water supply device can provide high-pressure water flow, which is delivered to the cleaning nozzles by the pump, ensuring that residues and dirt inside the nozzle orifices are thoroughly removed, improving the cleaning effect. The external water supply device can connect to different cleaning fluid sources, such as clean water and cleaning agent solutions, allowing for the selection of appropriate cleaning fluids according to different cleaning needs, improving the flexibility and adaptability of cleaning. Providing a water source through an external water supply device reduces the need for internal water storage devices, making the nozzle cleaning device lighter and easier to move and install.
[0019] Furthermore, the bottom of the bracket is provided with rollers.
