[0047] Monitoring records: When the nozzle 15 sprays the paint, the sensor monitors the working status of the nozzle 15 in real time, such as pressure, flow, temperature, etc., to ensure that the parameters are within the normal range. If the parameters are detected to deviate from the set value, the control system automatically adjusts until the parameters return to normal. After the system confirms that the calibration is completed, it prompts the operator through the display screen. The system records the data during the calibration process to a storage unit or uploads it to a computer or cloud server for subsequent analysis and management.

The rotary spraying device according to any one of claims 1 to 3, characterized in that: The top of the material storage barrel (1) is provided with a barrel cover (23), the barrel cover (23) is provided with the first drive motor (20) and a feed port (24), the interior of the material storage barrel (1) is provided with a paddle rod (25), the top of the paddle rod (25) passes through the barrel cover (23) and is connected to the output end of the first drive motor (20), and a plurality of propeller blades (26) are evenly arranged on the paddle rod (25) for evenly stirring the paint; The concentration detection mechanism comprises a probe (27) and a concentration detector (28); the probe (27) is arranged on the inner wall of the storage barrel (1); the concentration detector (28) is arranged on the outer wall; the probe (27) is connected to the concentration detector (28) and is used to detect the concentration of the coating.

10. A method for using a rotary spraying device, implemented by using the rotary spraying device according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1: pouring the paint into the storage barrel (2) through the feed port (24), starting the first drive motor (20) to drive the paddle rod (25) and the propeller blade (26) to stir the paint, and detecting the paint consistency through the probe (27) and the concentration detector (28); S2: After the paint reaches the required consistency, the cart (1) is pushed to the wall surface where the paint needs to be sprayed, and the pump (16) is started to transport the paint in the storage barrel (2) through the delivery pipe (17) to the spray pipe (14) and then spray it out through the nozzle (15); S3: starting the third driving motor (22) to drive the screw (19) to rotate and then drive the moving seat (3) to move up and down, so as to perform mobile spraying on the wall surface; S4: When the ceiling needs to be sprayed, the second drive motor (21) is started to drive the worm (11) to rotate, the worm (11) drives the worm wheel (10) to rotate, the worm wheel (10) drives the rotating sleeve (13) to rotate, the rotating sleeve (13) drives the spray pipe (14) and the nozzle (15) to flip through the insertion rod (5), and the paint is sprayed on the ceiling; S5: When the spraying range changes, the handle (8) is rotated to drive the bidirectional screw (6) to rotate so that the two screw pairs (7) and the holder (4) move away from each other, so that the rotating sleeve (13) on the holder (4) pulls out the plug rod (5) to replace the nozzle (15).
