[0039] As shown in Figure 4 The rotational adjustment mechanism 4 comprises a protective shell 401; The protective shell 401 is fixedly installed on the front side of the mounting frame 2, and the worm 402 is rotatably installed in the protective shell 401; The worm 402 is connected with the worm gear 403, and the worm gear 403 is fixedly connected with the end of the rotating shaft 201; The side of the protective shell 401 is fixedly installed with a motor 404, and the output shaft of the motor 404 is fixedly connected with the end of the worm 402.

[0040] The motor 404 drives the worm 402 to rotate, and the meshing transmission between the worm 402 and the worm gear 403 drives the rotating shaft 201 to drive the spray barrel 3 to rotate and adjust the spraying angle, and the angle-adjustable design meets the spraying operation in different angle directions.

[0041] As shown in Figure 2 And Figure 6 The top side and the bottom side of the movable ring 601 are fixedly installed with a frame 602, the frame 602 is rotatably installed with a hinge shaft 605, the hinge shaft 605 is fixedly connected with a connecting strip 603, and the connecting strip 603 is fixedly connected with the end cover 604. The reset torsion spring 606 is sleeved on the hinge shaft 605, and the two ends of the reset torsion spring 606 are connected with the frame 602 and the connecting strip 603 respectively.

[0042] As shown in Figures 1-2 At this time, the whole device is in idle state, the opening end of the spray barrel 3 is closed by the end cover 604, and the air inlet 304 is closed by the cover 802. Foreign matters are prevented from entering the spray barrel 3.

[0043] When the opening end of the spray barrel 3 is opened, the telescopic rod 7 is retracted, the movable ring 601 and the two end covers 604 on the movable ring 601 are moved away from the opening end of the spray barrel 3, the end cover 604 is pushed open through the opening end of the spray barrel 3, the end cover 604 is flipped open through the hinged shaft 605, and the reset torsion spring 606 is energized. After opening, as shown in Figure 7 .

[0044] When the opening end of the spray barrel 3 is re-opened, the telescopic rod 7 is extended, the movable ring 601 is reset, the end cover 604 is reset and flipped through the reset torsion spring 606, and is restored to the state as shown in Figures 1-2 .

[0045] Among them, the telescopic rod 7 is an electric push rod 9, a gas cylinder or a hydraulic cylinder.

[0046] As shown in Figure 1 and Figure 5 , the elastic movable cover 8 includes a guide seat 801; the guide seat 801 is fixedly connected with the side wall of the telescopic rod 7, the guide seat 801 is provided with a sliding channel in the length direction, the sliding channel is slidably connected with a sliding block 804, the sliding channel is provided with a spiral spring 805, the sliding block 804 is elastically connected with one end of the sliding channel through the spiral spring 805, and the sliding block 804 is fixedly connected with a cover body 802 through a connecting rod 803. The cover body 802 covers the outer wall of the spray barrel 3 at the position of the air inlet 304.

[0047] In specific implementation, the air inlet 304 position can be provided with a filter screen; for water mist spraying operation, in the open state of the air inlet 304, larger foreign matters are prevented from entering the air inlet 304.

[0048] Although the filter screen is provided to protect the air inlet 304, part of smaller foreign matters and dust can still enter through the mesh, and the purpose of the elastic movable cover 8 is to ensure that no foreign matter enters the air inlet 304 in the idle state of the entire device.

[0049] The opening of the elastic movable cover 8 is as follows: in the opening process of the sealing mechanism 6, the movable ring 601 drives the push rod 9 to move close to the cover body 802, provides a pushing force for the cover body 802, and makes the cover body 802 move away from the air inlet 304, so that the opening end of the spray barrel 3 is opened and the air inlet 304 is opened at the same time; when the cover body 802 moves away from the air inlet 304, the connecting rod 803 drives the sliding block 804 to slide in the sliding channel, and the spiral spring 805 is compressed to form a reset elastic force.

[0050] The closing of the elastic movable cover 8 is as follows: during the closing of the sealing mechanism 6, the movable ring 601 drives the push rod 9 away from the cover body 802, the cover body 802 loses the pushing force, and the sliding block 804, the connecting rod 803 and the cover body 802 are reset together through the compression elastic force of the spiral spring 805, and the cover body 802 covers the air inlet 304 again.

The side of the annular pipe 301 away from the spray head 302 is provided with a fan 303, and the fan 303 is fixedly installed in the spray barrel 3.

[0053] As shown in Figures 1-2 , the water supply mechanism 5 comprises a water tank 501, the inside of the water tank 501 is provided with a water pump 504, the water outlet end of the water pump 504 is connected with a hose 503, the hose 503 is connected with a straight pipe 505, the straight pipe 505 passes through the closed end of the spray barrel 3, and the straight pipe 505 is fixedly connected with the inner wall of the bottom of the spray barrel 3. The end of the straight pipe 505 away from the hose 503 is fixedly communicated with the annular pipe 301.

[0054] After the opening end of the spray barrel 3 and the air inlet 304 are opened, when spraying water mist, the water pump 504 pumps the water in the water tank 501, transports it through the hose 503 and the straight pipe 505, enters the annular pipe 301, and then sprays out from the spray head 302. At the same time, the fan 303 generates airflow, and the airflow and the water mist are sprayed out from the opening end of the spray barrel 3 together, so as to spray water mist on the construction site and reduce dust.

[0055] The top of the water tank 501 is provided with a water inlet, and the water inlet is provided with a sealing cover 502.

[0056] It also comprises a movable base 1, and the top surface of the movable base 1 is fixedly connected with the bottom surface of the mounting frame 2 and the bottom surface of the water tank 501.
