[0002] Municipal engineering refers to urban infrastructure construction projects, which cover all aspects of urban life and play a vital role in the normal operation and development of cities. Municipal engineering construction sites generate a large amount of dust. If the dust is not treated, it will fly in the air and affect the breathing of workers. At present, most dust suppression mechanisms for municipal engineering use water mist for dust suppression. During dust suppression, the nozzles are mostly fixed, and the water mist is sprayed from the same position, which cannot be evenly sprayed and the dust suppression effect is poor. Therefore, we propose a dust suppression mechanism for municipal engineering construction sites. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0016] Example 1:

[0017] Please see Figure 1 This utility model provides a technical solution: a dust suppression mechanism for municipal engineering construction sites, including a base 1, with four sets of universal wheels at the bottom of the base 1. The base 1 is characterized by: a water tank 2 at the top, a water pump 9 at the top of the water tank 2, a water supply pipe 8 connected to the output end of the water pump 9, a connecting pipe 7 at one end of the water supply pipe 8, four sets of connecting pipes 5 on the outer wall of the connecting pipe 7, the connecting pipes 5 being made of rubber material, and an outlet pipe 10 at one end of each of the four sets of connecting pipes 5, with an atomizing nozzle 6 at one end of the outlet pipe 10. The base 1 is topped with a vertical plate 3, and an adjustment mechanism 4 is provided on the side wall of the vertical plate 3.

[0018] Please see Figure 1 and Figure 3 The adjusting mechanism 4 includes a slide rod 48 on the side wall of the vertical plate 3. Four sets of sliders 49 are sleeved on the outer wall of the slide rod 48. Guide grooves are provided on the side wall of the vertical plate 3. Guide blocks matching the guide grooves are provided on the side walls of all four sets of sliders 49. Under the action of the guide grooves and guide blocks, the sliders 49 move more stably. The outer wall of the connecting pipe 5 is connected to the outer wall of the sliders 49. Three sets of return springs 400 are sleeved on the outer wall of the slide rod 48. The two ends of the return springs 400 are respectively connected to the side walls of two adjacent sets of sliders 49. Two sets of pressing blocks 47 are slidably connected to the side wall of the vertical plate 3. Two sets of limiting grooves are provided on the side wall of the vertical plate 3. Limiting blocks matching the limiting grooves are provided on the side walls of both sets of pressing blocks 47. Under the action of the limiting grooves and limiting blocks, the pressing blocks 47 move up and down. More stable, the extrusion block 47 is set in the shape of an isosceles trapezoid. The inclined surface of the extrusion block 47 cooperates with the slider 49. When the extrusion block 47 moves downward, it can extrude the slider 49. The slider 49 can move on the outer wall of the slide rod 48. The top of both sets of extrusion blocks 47 is provided with extrusion rods 40. The side wall of the vertical plate 3 is provided with a fixed plate 41. One end of both sets of extrusion rods 40 passes through the bottom of the fixed plate 41 and is connected to the movable plate 43 provided on the outside. The outer wall of both sets of extrusion rods 40 is fitted with springs 42. One end of the springs 42 is connected to the bottom of the movable plate 43, and the other end of the springs 42 is connected to the top of the fixed plate 41. The top of the vertical plate 3 is provided with a support plate 46. The outer wall of the support plate 46 is provided with a motor 45. The output end of the motor 45 is connected to a cam 44.

[0019] Working principle: Water pump 9 draws water from water tank 2 into connecting pipe 7 through water supply pipe 8, and then into atomizing nozzle 6 through water outlet pipe 5 for dust suppression. Motor 45 drives cam 44 to rotate. The protrusion of cam 44 can strike movable plate 43, which can compress spring 42. Movable plate 43 drives extrusion rod 40 and extrusion block 47 to move downward. The inclined surface of extrusion block 47 can compress slider 49, so slider 49 can move on the outer wall of slide rod 48. Slider 49 can compress and stretch spring 42, so slider 48 can drive water outlet pipe 10 to move back and forth. Atomizing nozzle 6 can spray dust evenly, with good dust suppression effect.
