[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, the utility model provides a technical solution: a dust suppression device for road construction, comprising a base plate 1, universal wheels 2 are fixedly installed at the four corners of the bottom of the base plate 1, support plates 3 are symmetrically fixedly installed on one side of the top of the base plate 1, and a wind tube 4 is rotatably installed on the top between the two groups of support plates 3, a positioning block 401 is fixedly installed on the top and bottom of one side of the wind tube 4, and the wind tube 4 is symmetrically provided with sockets 402 on both sides of the same end of the positioning block 401, and the sockets 402 correspond to the insertion rod 708, and a fan 403 is fixedly installed on the side of the wind tube 4 away from the positioning block 401. A mounting plate 703 is fixedly installed inside the mounting ring 7, and multiple groups of nozzles 704 are symmetrically fixedly installed on both sides of the mounting plate 703. Because the nozzles 704 and the fan 403 are provided, the fan 403 is started and the nozzles 704 are controlled to spray the liquid transported by the water pump 6 from the nozzles 704 to the construction site. Under the wind force of the fan 403, the liquid is blown to the construction site to suppress dust.

[0023] A mounting ring 7 is provided at one end of the air duct 4 away from the support plate 3, and a stepped groove 701 is provided on one side of the inner wall of the mounting ring 7. Positioning slots 702 are provided at the top and bottom of the stepped groove 701, and the positioning slots 702 correspond to the positioning block 401. Because the positioning block 401 and the positioning slots 702 are provided, it is ensured that when the mounting ring 7 is fixed to one side of the air duct 4, the positioning slots 702 can be stuck on the surface of the corresponding positioning block 401, thereby avoiding misalignment of the mounting ring 7 and the air duct 4 during connection and installation.

[0024] When the lock is unlocked, the lock is unlocked, and the lock is unlocked, so that the lock is unlocked. When the lock is unlocked, the lock is unlocked, and the lock is unlocked.

[0025] A stud 710 is fixedly installed at the central position of the connecting plate 706 near the side of the mounting ring 7, and the stud 710 passes through the sliding plate 707 and is fixedly connected to the mounting ring 7. A fixing screw sleeve 711 is provided on the surface of the stud 710 on the side of the sliding plate 707. Because of the fixing screw sleeve 711, after the mounting ring 7 is clamped and fixed to one end of the wind tube 4, the fixing screw sleeve 711 is tightened to press the sliding plate 707 against the surface of the mounting ring 7 to ensure that the insertion rod 708 will not detach from the socket 402 at will, causing the mounting ring 7 to fall off from one end of the wind tube 4.

[0026] The bottom of the surface of the air duct 4 is located on one side of the support plate 3 and is provided with two groups of electric push rods 5. A rotating frame 1 501 is fixedly installed at both ends of the electric push rod 5, and a rotating frame 2 502 is rotatably installed on the side of the rotating frame 1 501 away from the electric push rod 5. Because the electric push rod 5 is provided, the electric push rod 5 is controlled to extend and retract to lift one end of the air duct 4, thereby controlling the air duct 4 to rotate around the support plate 3, so that the air duct 4 can blow the liquid to a farther range.

[0027] A water pump 6 is fixedly mounted on the top of the base plate 1, on one side of the air duct 4, and is connected to the mounting ring 7. Support mechanisms 8 are symmetrically provided on both sides of the top of the base plate 1. The support mechanisms 8 include a mounting frame 801, with multiple sets of ground spikes 802 evenly fixedly mounted on one side of the mounting frame 801. Three sets of support rods 803 are equidistantly mounted on the side of the mounting frame 801 away from the ground spikes 802, and a rotating frame 3 804 is rotatably mounted on the end of the support rods 803 away from the mounting frame 801. The rotating frame 3 804 is fixedly connected to the base plate 1. By providing the ground spikes 802, the support rods 803 are rotated until the mounting frame 801 is flush with the ground, so that the ground spikes 802 are driven into the ground. This ensures that when the support rods 803 are tilted and supported on both sides of the base plate 1, the base plate 1 will not move freely on the ground.

[0028] The working principle of this utility model is:

[0029] After pushing the base plate 1 to the designated position at the construction site, step on the universal wheel 2 to brake and fix it, rotate the support rod 803 until the mounting bracket 801 is flush with the ground, drive the ground nail 802 into the ground, loosen the two sets of fixing screw sleeves 711, pull the sliding plate 707 to both sides to make the insertion rod 708 away from the step groove 701, clamp the step groove 701 on one end of the wind tube 4, so that the positioning slot 702 is clamped in the corresponding positioning block 401, ensure that the socket 402 corresponds to the insertion rod 708, loosen the sliding plate 707 and press it Under the rebound action of spring 709, the sliding plate 707 is pressed toward the mounting ring 7, so that the insertion rod 708 passes through the mounting ring 7 and is inserted into the corresponding socket 402. The fixing screw sleeve 711 is tightened to press the sliding plate 707 against the surface of the mounting ring 7, and the fan 403 and the water pump 6 are started, so that the fan 403 blows the liquid sprayed from the nozzle 704 to the construction site. The electric push rod 5 is controlled to extend and retract to lift the wind tube 4 and rotate it around the support plate 3, so that the wind tube 4 is tilted at the top of the base plate 1, and the liquid sprayed from the nozzle 704 is blown farther.
