[0002] The green construction of building projects is an important practice for the construction industry to actively respond to the concept of sustainable development. It emphasizes that during the construction process, by adopting measures such as using environmentally friendly materials, energy conservation and emission reduction technologies, and resource recycling, the negative impact on the environment is minimized to the greatest extent. Green construction not only focuses on the quality and efficiency of the building itself, but also attaches great importance to environmental protection and ecological balance during the construction process.

[0003] During the construction of building projects, when ground drilling operations are carried out, during the drilling process, a large amount of dust is likely to diffuse uncontrollably, the dust accumulates and rises and spreads, seriously polluting the construction site environment. The dispersion of the dust increases the purification burden on the surrounding environment. At the same time, these dusts not only threaten the respiratory health of construction workers, but may also adhere to the surface of building materials, affecting the project quality.

[0004] Therefore, a spray dust reduction device for green construction of building projects is needed to solve the problems raised in the above background technique. Content of the Utility Model

When in use, the whole device is moved to the ground drilling operation area, and the bracket plate 3 is located directly above the ground drilling operation area. The servo motor 7 is started to work. The lead screw 4 is driven to rotate forward and backward reciprocally through the output end of the servo motor 7, and the lead screw nut 15 is guided and limited through the cooperation of the convex rod 14 and the chute b 13, so that the rotating lead screw 4 drives the lead screw nut 15 to move reciprocally. During this process, the lead screw nut 15 drives the external cylinder 5 and the spraying and spreading assembly 1 at the bottom of the sliding rod 16 to move synchronously. The liquid inlet pipe 6 is externally connected to a water pump, and liquid water is conveyed to the inside of the spraying and spreading assembly 1 through the liquid inlet pipe 6, and the water is evenly and finely sprayed out through the spraying and spreading assembly 1 to adsorb and descend the dust generated during the ground drilling operation, realizing dust suppression, reducing the pollution of the dust generated during the operation to the surrounding environment. The spraying range of water can be effectively increased through the arranged spraying and spreading assembly 1 and the reciprocating movement of the spraying and spreading assembly 1, effectively improving the dust suppression effect.

[0022] Further, as Figure 1 , Figure 2 and Figure 4As shown, it is worth specifically explaining that the spraying assembly 1 includes a connecting pipe 106 rotatably connected to the bottom end of the sliding rod 16. A sprinkler head 101 is fixed to the bottom end of the connecting pipe 106. A cavity 108 communicating with the connecting pipe 106 is formed inside the sprinkler head 101. Water outlet holes 104 communicating with the cavity 108 are formed on the cylindrical side surface of the sprinkler head 101. There are multiple water outlet holes 104, and the multiple water outlet holes 104 are equidistantly distributed. A water trough 107 is formed inside the sliding rod 16. The two ends of the water trough 107 are respectively communicated with the liquid inlet pipe 6 and the connecting pipe 106.

During specific operation, the output end of the first motor 105 drives the second gear 103 to rotate, so as to drive the connecting pipe 106 to rotate through the cooperation of the second gear 103 and the first gear 102. The connecting pipe 106 drives the sprinkler head 101 to rotate synchronously. By utilizing the centrifugal force, the spraying range of water can be effectively increased, and the dust reduction effect can be effectively improved.

A rack plate 201 slidably adapted to the chute a203 is fixed to the side surface of the sliding rod 16. A second motor 204 is fixed to the outer side wall of the outer cylinder 5. A third gear 202 meshingly connected with the rack plate 201 is fixed to the output end of the second motor 204.
