[0026] As a preferred embodiment of this example, Figures 1-3As shown, a collection box 2 is fixedly connected to the upper surface of the equipment base plate 1. A distributor 3 is fixedly connected to the lower end of the collection box 2. The lower surface of the distributor 3 is provided with four distribution pipes. Four distribution holes are opened at the bottom inside the distributor 3. The distribution holes and distribution pipes are compatible with each other. A fixing plate 4 is fixedly connected to the upper surface of the equipment base plate 1. A fixing hydraulic rod 5 is fixedly connected to the left side of the fixing plate 4. A motor base 6 is inserted into the left end of the fixing hydraulic rod 5. A drive motor 7 is fixedly connected inside the motor base 6. A drive shaft 8 is inserted into the upper end of the drive motor 7. A turntable 9 is rotatably connected to the upper end of the surface of the drive shaft 8.

During use, the water pump 15 continuously supplies water from the water tank 14 to the nozzle holder 17 via the hose 16. Water is continuously sprayed into the collection tank 2 through the nozzle holder 17 and the cleaning nozzle 18. When the water flows through the distributor 3, the fixed hydraulic rod 5 moves the motor base 6 to the left, and the lifting hydraulic rod 10 moves the base 11 upward, thereby inserting the cleaning roller 13 into the first distribution pipe. The cleaning motor 12 drives the cleaning roller 13 to clean the inside of the first distribution pipe. After cleaning, the lifting hydraulic rod... 10 causes the base 11 to move downward, thereby separating the cleaning roller 13 from the first distribution tube. The drive motor 7 rotates the rotating shaft 8, causing the turntable 9 to rotate. Then, the lifting hydraulic rod 10 moves the base 11 upward, allowing the cleaning roller 13 to insert into the second distribution tube. The cleaning motor 12 drives the cleaning roller 13 to clean the inside of the second distribution tube. This process is repeated for all four distribution tubes. This solves the problem of uneven liquid distribution caused by pipe blockage due to long-term use of the internal pipes of the distributor 3. It achieves the effect of cleaning multiple pipes inside the distributor 3 to ensure unobstructed flow, greatly reducing the uneven distribution caused by the distributor 3.

[0027] like Figure 4 and Figure 5As shown, in this embodiment, a connecting hole is provided at the bottom of the collection box 2. A fixed motor 19 is fixedly connected to the collection box 2 through the connecting hole. A fixed rotating shaft 20 is inserted into the upper end of the fixed motor 19. A baffle 21 is rotatably connected to the upper end of the surface of the fixed rotating shaft 20. The collection box 2 is rotatably connected to the fixed rotating shaft 20 through the connecting hole. The baffle 21 is compatible with the distributor 3.

A cleaning hydraulic rod 27 is fixedly connected inside the cover plate 26. A fixing seat 28 is inserted into the front end of the cleaning hydraulic rod 27. A docking motor 29 is fixedly connected inside the fixing seat 28. A docking shaft 30 is inserted into one end of the docking motor 29. A bracket 31 is rotatably connected to the surface of the docking shaft 30. A cleaning hole is opened on the right side of the bracket 31. A cleaning roller 32 is rotatably connected to the bracket 31 through the cleaning hole. The cleaning roller 32 is compatible with the interior of the collection box 2. A drive groove is opened on the upper surface of the equipment base plate 1. A driver is installed inside the drive groove. The driver model is DM556. This driver is a digital two-phase stepper motor driver based on a 32-bit motor dedicated processor and can be set to 400. The subdivision within ~51200 and any current value within the rated current can meet the application needs of most occasions. The drive integrates an automatic motor parameter recognition function, which can identify different specifications of 57 / 60 motors and automatically generate optimal operating parameters to maximize the performance of the motor. The motor runs smoothly with low vibration, low noise, and high output. During use, the fixed motor 19 drives the fixed shaft 20 to block the lower part of the baffle 21 from the upper surface of the distributor 3. When in use, the fixed motor 19 drives the fixed shaft 20 to separate the lower part of the baffle 21 from the upper surface of the distributor 3, allowing the distributor 3 to perform flow splitting operation. By rotating the motor 23 to drive the connecting shaft 24, the upper shaft seat 25 and the cover plate 26 rotate. The cover plate 26 closes the upper end of the collection box 2. After closing, the water pump 15 continuously supplies water from the inside of the water tank 14 to the nozzle seat 17 through the hose 16. Water is continuously sprayed into the inside of the collection box 2 through the nozzle seat 17 and the cleaning nozzle 18. The docking motor 29 drives the docking shaft 30 to rotate the bracket 31. The rotation of the bracket 31 allows the cleaning roller 32 to clean the inner wall of the collection box 2. At the same time, the cleaning hydraulic rod 27 moves the fixed seat 28 downward to clean the inner wall of the collection box 2. This solves the problem of residual liquid inside the collection box 2 after liquid distribution affecting its reuse. It achieves the effect of rinsing the inside of the collection box 2 and cleaning the inner wall at the same time, greatly enhancing the cleanliness of the equipment.

[0028] The working principle of this practical application is as follows:

[0029] During use, water pump 15 continuously supplies water from inside water tank 14 to nozzle seat 17 via hose 16. The nozzle seat 17 and cleaning nozzle 18 continuously spray water into collection tank 2. When the water flows through distributor 3, the fixed hydraulic rod 5 moves motor seat 6 to the left, and the lifting hydraulic rod 10 moves base 11 upward, allowing cleaning roller 13 to insert into the first distribution pipe. Cleaning motor 12 drives cleaning roller 13 to clean the inside of the first distribution pipe. After cleaning, the lifting hydraulic rod 10 moves base 11 downward, thus... The cleaning roller 13 separates from the first distribution pipe. The drive motor 7 rotates the rotating shaft 8, causing the turntable 9 to rotate. The lifting hydraulic rod 10 then moves the base 11 upwards, allowing the cleaning roller 13 to insert into the second distribution pipe. The cleaning motor 12 drives the cleaning roller 13 to clean the inside of the second distribution pipe. This process is repeated for all four distribution pipes, solving the problem of uneven liquid distribution caused by pipe blockage due to prolonged use of the distributor 3. It achieves the effect of cleaning multiple pipes inside the distributor 3, ensuring unobstructed flow. This greatly reduces the possibility of uneven distribution by the distributor 3. A fixed motor 19 drives a fixed rotating shaft 20, causing the lower part of the baffle 21 to block the upper surface of the distributor 3. During use, the fixed motor 19 drives the fixed rotating shaft 20 to separate the lower part of the baffle 21 from the upper surface of the distributor 3, allowing the distributor 3 to perform flow distribution. A rotating motor 23 drives a connecting rotating shaft 24, causing the upper shaft seat 25 and the cover plate 26 to rotate, thus closing the upper end of the collection tank 2 with the cover plate 26. After closing, the water pump 15 continuously supplies water from the water tank 14 to the nozzle seat 17 via the hose 16. Water can be continuously sprayed into the inside of the collection box 2 through the nozzle seat 17 and the cleaning nozzle 18. The docking motor 29 drives the docking shaft 30 to rotate the bracket 31. As the bracket 31 rotates, the cleaning roller 32 can clean the inner wall of the collection box 2. At the same time, the cleaning hydraulic rod 27 moves the fixed seat 28 downward to clean the inner wall of the collection box 2. This solves the problem of residual liquid inside the collection box 2 after liquid distribution affecting its reuse. It achieves the effect of rinsing the inside of the collection box 2 and cleaning the inner wall at the same time, which greatly enhances the cleanliness of the equipment.
