[0068] The use process of the spraying device 1 provided in this embodiment is as follows: when in use, the bolts on the two rotating plates are unscrewed to release the restrictions on the two rotating plates, and the rotating unit 2218 is flipped. At this time, the protective cavity is opened, and then the movable rod 122 is rotated to open the accommodating cavity 11. The movable rod 122 drives the upper fixing seat 15 and the corrugated tube 13 to move. At this time, the U-shaped frame is set on the steel bar column to be sprayed, and then the movable rod 122 is flipped to close the accommodating cavity 11, and the rotating unit 2218 is flipped and closed and the fixing bolts are tightened. At this time, the steel bar column to be sprayed is surrounded by the spray head 14 on all sides, and the corrugated tube 13 is connected to an external water pump to extract the rust remover, so that the rust remover passes through the spray head 14. A plurality of nozzles 14 are used to spray around the steel bar column to be sprayed to remove rust on the steel bar column to be sprayed. During the process, the staff can hold the handle 34 to adjust the height up and down, and the height can be further adjusted. The adjusting tube 332 is rotated, and the adjusting tube 332 will rotate on the two limiting rings 334 through two annular grooves respectively, so as to prevent the adjusting tube 332 from slipping. The adjusting tube 332 is continuously rotated, and the adjusting tube 332 drives the threaded tube 331 to rotate. The rotating threaded tube 331 drives the screw rod to move vertically. The vertically moving screw rod drives the fixed block 35 to move, and then the fixed block 35 drives the guide rod 36 to slide in the guide groove, thereby limiting the movement of the screw rod. The height of the screw rod and the fixing block 35 can be adjusted by rotating the adjusting tube 332 forward and backward, so as to facilitate adjustment according to the height of the steel bar column to be sprayed. During the spraying process, the U-shaped protective plate and the connecting baffle 2219 are used to block the wind and prevent the mist of the rust remover from drifting out. The two U-shaped frames are adjusted according to the environmental conditions. The knobs 2225 on both sides are turned so that the knobs 2225 drive the screw rod 2221 to rotate. The continuously rotating screw rod 2221 drives the linkage block 2222 to slide in the direction of the U-shaped frame. The sliding linkage block 2222 drives one end of the first connecting rod 2223 and the second connecting rod 2224 to flip and move The first U-shaped frame 2212 and the second U-shaped frame 2213 are moved so that the other ends of the first connecting rod 2223 and the second connecting rod 2224 respectively push the first U-shaped frame 2212 and the second U-shaped frame 2213 to move away from each other. The moving first U-shaped frame 2212 slides on the first limiting rod 2216 through the first limiting groove, and the moving second U-shaped frame 2213 slides on the second limiting rod 2217 through the second limiting groove, thereby limiting the sliding direction of the U-shaped frame. The continuously sliding U-shaped frame will drive the rotating plate to slide on the connecting baffle 2219. During the movement of the rotating plate, the gap can be blocked by setting the connecting baffle 2219, thereby extending the range of wind and fog blocking.
