One end of the transmission pipe 5 penetrates through the top of the tank cover 2 and is placed inside the mixing tank 1. A support component 7 is arranged at one end of the transmission pipe 5. When the cleaning motor 4 is started, the cleaning motor 4 drives the transmission pipe 5 to rotate through the second gear 10 and the first gear 9. The transmission pipe 5 drives the mud scraping frame 8 to rotate. The mud scraping frame 8 will scrape the drilling mud attached to the inner wall of the mixing tank 1, realizing the cleaning of the inner wall of the mixing tank 1.

[0026] The top of the bracket 3 is fixedly provided with a stirring motor 11. The transmission shaft of the stirring motor 11 is fixedly provided with a stirring rod 12. Main stirring plates 13 and auxiliary stirring plates 14 are respectively fixedly provided on the surface of the stirring rod 12. There are eight main stirring plates 13 and two auxiliary stirring plates 14. The contact part between the stirring rod 12 and the bracket 3 is rotatably connected through a sealing bearing. When the stirring motor 11 is started, the stirring motor 11 will drive the main stirring plates 13 and the auxiliary stirring plates 14 to rotate through the stirring rod 12. The main stirring plates 13 and the auxiliary stirring plates 14 stir the oil and chemical treatment agents inside the mixing tank 1 to complete mud mixing.

[0027] The transmission pipe 5 is sleeved outside the stirring rod 12. The surface of the mud scraping frame 8 is slidably connected to the inner wall of the mixing tank 1. A stable seat 15 is fixedly provided on the inner wall of the bottom end of the mud scraping frame 8. The contact part between the stable seat 15 and the stirring rod 12 is rotatably connected through a sealing bearing. When the mud scraping frame 8 is idle, it is fixed by the limiting component 6 through the transmission pipe 5. At this time, the mud scraping frame 8 remains stationary and limits the end of the rotating stirring rod 12 through the stable seat 15, improving the stability of the stirring rod 12 during rotation.

[0028] The limiting component 6 includes a clamping seat 61, a guiding frame 62 and a baffle 63. The clamping seat 61 is fixedly arranged on the surface of the transmission pipe 5. A clamping groove 66 is formed on the back surface of the clamping seat 61. Both the guiding frame 62 and the baffle 63 are fixedly arranged at the top end of the tank cover 2. An electric push rod 64 is fixedly arranged on the back surface of the baffle 63. A clamping bar 65 which is engaged with the clamping groove 66 is fixedly arranged at the telescopic end of the electric push rod 64.

A laser distance sensor 67 is fixedly arranged on the front surface of the guiding frame 62. The laser distance sensor 67 measures the distance between the laser distance sensor 67 and the clamping seat 61, and transmits the measured value to the single-chip microcomputer inside the touch all-in-one machine body 76. A program is preset inside the single-chip microcomputer. When the stirring motor 11 is turned off by using the touch all-in-one machine body 76, the single-chip microcomputer will compare the measured value with the preset value of the program. When the measured value is equal to the preset value, it indicates that the clamping groove 66 is aligned with the clamping bar 65. At this time, the single-chip microcomputer will automatically turn off the stirring motor 11. When the measured value is not equal to the preset value, it indicates that the clamping groove 66 is not aligned with the clamping bar 65, and the single-chip microcomputer keeps the stirring motor 11 rotating until the measured value is equal to the preset value, so as to ensure that the clamping groove 66 is automatically aligned with the clamping bar 65 after the stirring motor 11 is turned off, facilitating the use of the limiting component 6. It should also be emphasized that on the premise that the worker does not turn off the stirring motor 11 by using the touch all-in-one machine body 76, even if the measured value is equal to the preset value, the stirring motor 11 will not be automatically turned off, thus avoiding the interruption of the process of stirring and mixing the mud by this program.

Then start the electric push rod 64. The telescopic end of the electric push rod 64 will extend and push the clamping strip 65 to move, so that the clamping strip 65 is clamped into the clamping groove 66 to complete the fixation of the transmission pipe 5, avoiding the transmission pipe 5 and the mud scraping frame 8 from being rotated by the moving mud when stirring the mud. Finally, start the cleaning motor 4 through the touch all-in-one machine body 76. The cleaning motor 4 drives the transmission pipe 5 to drive through the second gear 10 and the first gear 9. The transmission pipe 5 drives the mud scraping frame 8 to rotate. The mud scraping frame 8 scrapes the drilling mud attached to the inner wall of the mixing tank 1 to realize the cleaning of the inner wall of the mixing tank 1. After cleaning, open the electric valve 22 to discharge the sewage and control the clamping strip 65 to return to its original position through the touch all-in-one machine body 76, and then it is ready for the next mud mixing. Compared with the prior art, there is no need to manually lift the top cover and rotate multiple screws before and after cleaning the mixing tank 1, reducing the labor intensity and being convenient to use.
