Description

Technical Field

[0001] The utility model relates to the technical field of dust treatment, in particular to a road construction dust control device. Background Art

[0002] Dust is a solid suspended matter in the atmosphere. It normally exists in the air and is easily scattered everywhere with the wind. Dust is the enemy of human health, so people hate it very much. Dust carries many bacteria, viruses and insect eggs flying everywhere, spreading diseases. Dust is an open pollution source that enters the atmosphere due to the dust on the ground driven by wind, human factors and other factors. It is an important component of the total suspended particulate matter in the ambient air, making the air polluted, affecting the environment, and also harmful to the human body, such as bronchitis and lung cancer. When the road is under construction, the construction equipment may cause dust on the ground to be raised when it is moving or working, making the air polluted and affecting the environment. Therefore, during the construction, corresponding dust control devices need to be used to deal with the dust.

[0003] The prior art authorization announcement number is CN 215539447 U, which is a dust prevention device for road construction. It includes a water tank, a tank cover, a telescopic rod, a water pump and an atomizing nozzle. The tank cover is arranged at the opening at the upper end of the water tank.

When using this device to perform dust reduction operations, the user can control the motor 68 to work through the controller 3. When the motor 68 is working, the reciprocating screw 62, the reciprocating screw nut 66 and the translation plate 65 drive the diverter pipe 611 and the nozzle 612 to move back and forth left and right, thereby utilizing the left and right reciprocating movement of the nozzle 612 to increase the operating range and improve the dust reduction effect.
