[0019] Example: Figure 1-4 As shown, this embodiment mainly includes an automatic rotating base 1, a central fixed spindle 2, an adjustable scraping support 4 and a vibrating scraper 5. The automatic rotating base 1 is arranged in the conical pool body 6 and is arranged coaxially with the conical pool body 6. The upper part of the automatic rotating base 1 is connected with the central fixed spindle 2, and the two sides of the central fixed spindle 2 are symmetrically provided with adjustable scraping supports 4, and the ends of the adjustable scraping supports 4 are connected with a vibrating scraper 5, which is arranged on the side surface of the conical pool body 6. The automatic rotating base 1 can drive the central fixed spindle 2, the adjustable scraping support 4 and the vibrating scraper 5 on its upper part to rotate in sequence by rotation, that is, the automatic rotating base 1 drives the central fixed spindle 2 to rotate by rotation, and the central fixed spindle 2 drives the adjustable scraping support 4 to rotate, and then the adjustable scraping support 4 drives the vibrating scraper 5 to rotate, and finally the vibrating scraper 5 completes the scraping work on the side surface of the conical pool body 6.

[0020] like Figure 1 and Figure 2As shown, the automatic rotating base 1 includes a support 11, a motor 12, a battery 13, a turntable 14, a gear plate 15 and a gear 16. The motor 12 and the battery 13 are respectively installed on both sides of the bottom of the support 11. The motor 12 and the battery 13 are installed at the bottom of the support 11 to reduce the overall center of gravity and improve the stability of the device. The lower layer of the turntable 14 is firmly welded to the top of the support 11, and the upper layer of the turntable 14 is welded with a gear plate 15. The support 11, the turntable 14 and the gear plate 15 are located at the same axis, and the middle is a hollow structure, and the central fixed main shaft 2 can be inserted into it. A gear 16 is provided at the end of the rotating shaft of the motor 12, and it is meshed with the gear plate 15. The rotation of the motor 12 can drive the gear plate 15 to rotate to realize the unified rotation of the upper structure of the gear plate 15. At the same time, the opening and closing of the motor 12 and its speed can be controlled by the remote control, thereby controlling whether the device is working and the scraping rate.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the central fixed spindle 2 is fixed on the upper part of the automatic rotating base 1, and a vertical axle plate 24 is arranged around the central fixed spindle 2 to enhance its stability, wherein the axle plate 24 is fixed to the gear plate 15 by a first screw 25. The upper part of the central fixed spindle 2 is threaded, that is, the upper part of the central fixed spindle 2 is a spindle screw 21, and a threaded sleeve 22 is installed on the spindle screw 21. By rotating the threaded sleeve 22, the upper and lower positions of the threaded sleeve 22 can be adjusted on the spindle screw 21. A first nut 23 is respectively arranged on the upper and lower parts of the threaded sleeve 22, and the two first nuts 23 are both arranged on the threaded section of the spindle screw 21, and the position of the threaded sleeve 22 can be fixed. A pair of ear plates 3 are respectively arranged on the upper and lower ends of the threaded sleeve 22, and the four ear plates 3 are located in the same plane and are symmetrically distributed, and are used to fix the adjustable scraping support 4.

[0022] like Figure 1 , Figure 3 and Figure 4As shown, the adjustable scraping support 4 is symmetrically arranged on both sides of the central fixed main shaft 2, and the adjustable scraping support 4 includes an upper telescopic rod 41, a lower telescopic rod 42 and a telescopic support rod 43, and the three are located in the same plane, wherein the upper telescopic rod 41 and the lower telescopic rod 42 are arranged parallel to each other. The upper telescopic rod 41, the lower telescopic rod 42 and the telescopic support rod 43 are all composed of a sleeve 45 and two screw rods 44 connected to both ends of the sleeve 45, and the external threads of the two screw rods 44 are adapted to the internal threads of the sleeve 45. By rotating the sleeve 45, the length of the two screw rods 44 on the upper telescopic rod 41, the lower telescopic rod 42 and the telescopic support rod 43 can be adjusted, thereby realizing the extension and shortening of the upper telescopic rod 41, the lower telescopic rod 42 and the telescopic support rod 43. The ends of the upper telescopic rod 41 and the lower telescopic rod 42 are respectively connected to the ear plate 3 on the threaded sleeve 22 of the central fixed main shaft 2 and the ear plate 3 on the scraping ruler 51 of the vibrating scraper 5, and the upper telescopic rod 41 and the lower telescopic rod 42 can rotate around the ear plate 3 on the threaded sleeve 22 and the ear plate 3 on the scraping ruler 51 of the vibrating scraper 5. Specifically, the upper telescopic rod 41 is connected to the ear plate 3 at the upper end of the threaded sleeve 22, and the lower telescopic rod 42 is connected to the ear plate 3 at the lower end of the threaded sleeve 22. One end of the telescopic support rod 43 is welded and fixed to the central fixed main shaft 2 and cannot rotate, and the other end is fixed to the lower end screw rod 45 of the lower telescopic rod 42 through the ear plate 3, and this end of the telescopic support rod 43 can rotate around the ear plate 3 on the lower end screw rod 45 of the lower telescopic rod 42.

[0023] In this embodiment, the position of the highest point of the adjustable scraping support 4 can be adjusted by adjusting the position of the threaded sleeve 22 on the central fixed spindle 2; the height of the upper telescopic pull 41 and the lower telescopic pull 42 can be adjusted by adjusting the length of the telescopic support rod 43 to determine the height of the scraping area; the upper radius of the scraping area can be adjusted by adjusting the length of the upper telescopic pull rod 41, and the lower radius of the scraping area can be adjusted by adjusting the length of the lower telescopic pull rod 42.

An ear plate 3 is installed at each end of the scraping ruler 51, and the two ear plates 3 are respectively connected to the upper telescopic pull rod 41 and the lower telescopic pull rod 42. The small vibrator 52 is fixed to the middle of the scraping ruler 51 through two fixing rods 53. One end of the two fixing rods 53 is welded to the two sides of the small vibrator 52, and the other ends of the two fixing rods 53 are connected to the ear plates 3 at both ends of the scraping ruler 51. In this way, vibration can be performed while scraping to ensure that the concrete surface is dense and flat. The small vibrator 52 can also be turned on, off and the amplitude can be adjusted by a remote control.

[0025] In this embodiment, the ear plate 3 on the threaded sleeve 22 of the central fixed spindle 2, the ear plate 3 on the lower telescopic pull rod 42 of the adjustable scraping support 4, and the ear plate 3 on the scraping ruler 51 of the vibrating scraper 5 are connected in the same manner, so only the ear plate 3 at the upper end of the threaded sleeve 22 of the central fixed spindle 2 is taken as an example for this description. Figure 3 As shown, the ear plate 3 is a steel plate with a hole in the middle, and the end of the component connected to the ear plate 3 (in this embodiment, the upper telescopic pull rod 41 of the adjustable scraping support 4) is also welded with a steel plate with a hole in the middle, and the second screw 31 passes through the above two holes and is connected and fixed by the second nut 32.

[0026] In addition, combined Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment also has the following working method:

[0027] 1. According to the size, height and slope of the conical pool body, the upper and lower radii of the scraping area and the inclination angle of the scraping are determined by adjusting the position of the threaded sleeve 22 on the central fixed main shaft 2, as well as the lengths of the upper telescopic rod 41, the lower telescopic rod 42 and the telescopic support rod 43;

[0028] 2. Install the device, debug it, and adjust the working state of the motor 12 and the small vibrator 52 through the remote control according to the actual situation, so as to ensure that the concrete surface is dense and flat while scraping. The working state of the motor 12 includes on, off and motor speed, and the working state of the small vibrator 52 includes on, off and amplitude;

[0029] 3. After the scraping work is completed, sort out and recycle the device.
