Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides a technical solution:

[0025] A dust suppressor for construction projects includes a mobile cart 1, with a battery pack 4 fixedly mounted on top of the cart 1. The interior of the cart 1 is equipped with a dust suppressing mechanism 2 to expand the dust suppressing space. The dust suppressing mechanism 2 includes:

[0026] Water supply unit 21 is installed inside the mobile cart 1 and is used to provide clean water;

[0027] Angle unit 22 is installed inside the mobile trolley 1 and is used to adjust the dust falling direction;

[0028] The spray unit 23 is located above the mobile cart 1 and includes a set of fixed steel pipes 231 fixedly installed on the front and rear sides of the mobile cart 1 via a folding assembly 3. Several fixed rods 232 are installed on the surface of the fixed steel pipes 231. A rotating pipe 233 is rotatably installed at the bottom end of the fixed rod 232. A spray head 234 is fixedly installed at one end of the rotating pipe 233. A connecting water pipe 239 is fixedly installed on one side of the fixed rod 232. A connecting pipe 2310 is fixedly installed above the connecting water pipe 239. One end of the connecting pipe 2310 passes through the interior of the fixed steel pipe 231 to connect with the several connecting water pipes 239, thereby expanding the dust suppression space.

[0029] Clean water is fed into the connecting water pipe 239 through the connecting pipe 2310 via the water supply unit 21, and then into the rotating pipe 233 through the connecting water pipe 239. The water is then sprayed out through the spray head 234, thereby achieving multi-point spray dust suppression and increasing the lateral dust suppression space.

[0030] In this embodiment, a fan 235 is fixedly mounted on the surface of the rotating tube 233, and a gear ring 236 is fixedly mounted on the surface of the rotating tube 233. A mounting base 2311 is fixedly mounted at the bottom end of the fixing rod 232. A micro motor 237 is fixedly mounted on one side of the mounting base 2311, and a drive gear 238 is fixedly mounted through the mounting base 2311 at the output end of the micro motor 237. The drive gear 238 meshes with the gear ring 236 to increase the spray distance of the spray head 234.

[0031] The micro motor 237, model KV3SF-8521F-WR, is electrically connected to an external power source and can be turned on and off via a human-operated control panel. When the micro motor 237 runs, it drives the drive gear 238 to rotate, which in turn drives the fan 235 to rotate. The fan 235 then drives the rotating pipe 233 to rotate, which in turn drives the fan 235 and the spray head 234 to rotate, thus increasing the spray distance.

[0032] In this embodiment, the water supply unit 21 includes a water tank 211 fixedly installed on the bottom plate of the mobile cart 1, a water pump 212 fixedly installed on the bottom plate of the mobile cart 1, and the water tank 211 and the water pump 212 are connected by a pipe. The output end of the water pump 212 is fixedly installed with a water pipe 213, and the water pipe 213 is connected to the connecting pipe 2310.

[0033] The water pump 212 is model 42113-25A. It is electrically connected to an external power source and can be started and stopped by a human control panel. When the water pump 212 is running, it pumps clean water from the water tank 211 into the connecting pipe 2310 through the water pipe 213.

[0034] In this embodiment, the angle unit 22 includes a connecting base 221 fixedly installed above the mobile trolley 1, and a connecting top seat 222 rotatably installed above the connecting base 221. A connecting rod 224 is fixedly installed on one side of the connecting top seat 222. A connecting seat 223 is fixedly installed above the mobile trolley 1. An electric push rod 225 is connected between the connecting seat 223 and the electric push rod 225. The electric push rod 225 is connected to the battery pack 4 via a wire.

[0035] The electric push rod 225, model SLEL205, is electrically connected to an external power source and is operated by a human-controlled control panel. During the dust suppression spraying process, the electric push rod 225 reciprocates and drives the connecting top seat 222 to reciprocate and rotate through the connecting rod 224, thereby realizing the up and down spraying dust suppression of the spraying unit 23.

[0036] In this embodiment, the folding assembly 3 includes a first rotating seat 31 and a second rotating seat 32 rotatably mounted on the top of the connecting top seat 222, and a fixed steel pipe 231 is fixedly mounted inside the first rotating seat 31 and the second rotating seat 32 respectively for folding the fixed steel pipe 231. A rotating post 33 is fixedly mounted on one side of the first rotating seat 31, and a locking post 34 is fixedly mounted on one side of the second rotating seat 32. A locking rod 35 is rotatably mounted on one end of the rotating post 33, and one end of the locking rod 35 is locked with the locking post 34.

[0037] The first rotating seat 31 and the second rotating seat 32 drive the fixed steel pipe 231 to rotate into a horizontal state, and by rotating the locking rod 35, the locking rod 35 and the locking post 34 are locked together, thereby fixing and folding the position of the fixed steel pipe 231.

[0038] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0039] During operation, firstly, the first rotating seat 31 and the second rotating seat 32 drive the fixed steel pipe 231 to rotate to a horizontal state, and by rotating the clamping rod 35, the clamping rod 35 is locked with the clamping post 34 to fix the position of the fixed steel pipe 231.

[0040] Next, the water pump 212 operates, drawing clean water from the water tank 211 into the connecting pipe 2310 through the water pipe 213. The water then flows into the connecting pipe 239 through the connecting pipe 2310, and finally into the rotating pipe 233 through the connecting pipe 239. The water is then sprayed out through the spray head 234. Simultaneously, the micro motor 237 operates, driving the drive gear 238 to rotate. The drive gear 238 drives the fan 235 to rotate, which in turn drives the rotating pipe 233 to rotate. The rotating pipe 233 then drives the fan 235 and the spray head 234 to rotate, increasing the spray distance.

[0041] Then, during the dust suppression spraying process, the electric push rod 225 reciprocates and drives the connecting top seat 222 to reciprocate and rotate through the connecting rod 224, thereby realizing the up and down spraying dust suppression of the spraying unit 23.
