Description

Technical Field

[0001] The utility model relates to the technical field of dust suppression devices, in particular to a dust suppression device for building construction. Background Art

[0002] With the rapid development of social economy, in the early stage of construction, the road surface of the construction site is all earth road surface, and the construction environment of the construction site is relatively poor. During the construction, dust pollution is one of the important items. In order to control dust, construction sites often take a series of control measures, such as covering the surface of sand and gravel with dust nets, spraying water on the construction site, setting up nozzles and washing pools for washing vehicles at the vehicle entrances and exits, and the transport vehicles entering and leaving the construction site must be clean and must not pollute the road. The transport vehicles must leave the construction site after being washed clean to prevent the vehicles from taking mud and sand out of the site. Taking corresponding measures has reduced dust to a certain extent.

[0003] Chinese utility model disclosure CN212594666U discloses a dust suppression device for construction. A dust suppression device with adjustable height is designed to facilitate different usage needs. The principle is that a plurality of adjusting thread grooves are opened on the outer wall of a water tank, and then a slide groove is opened on one side of the water tank. At the same time, an atomizing nozzle is connected to a slider, and the slider slides inside the slide groove. By adjusting the height of the atomizing nozzle, after adjusting to a suitable height, the positioning bolt needs to be rotated so that one end of the positioning bolt is inserted into the inside of the adjusting thread groove to complete the fixation of the atomizing nozzle, and then a water pump is used to supply water to generate water vapor for dust reduction.

[0004] However, when the existing device is adjusted, the atomizing nozzle will block the adjustment thread groove when it moves, so that the positioning bolt needs to be inserted after multiple attempts, and the rotation adjustment method is slow and inefficient. Therefore, a snap-on adjustment method is designed to solve the above problems, which makes the adjustment faster and more efficient. Utility Model Content

The top inner side wall slope of the slot 22 is in contact with the top slope of the block 26. The adjusting component 2 also includes: a pull button 28, which is provided at the top of the pull rod 27. The adjusting component 2 also includes: a cross bar 29, which is provided on one side of the water storage tank 12, and the two ends are correspondingly connected to the moving block 23.

[0031] When in use, use the cart 11 to move the water tank 12 to the place where dust reduction is required, then adjust the height of the cross pipe 14 to align it with the area where dust reduction is required, then hold the cross bar 29. When holding it, the sponge cover 291 can make the surface softer, and then pull the cross bar 29 upward to make the moving block 23 slide upward on the rectangular slide bar 21. At this time, the card block 26 is squeezed and retracted into the inside of the slot 24 by the card slot 22. At the same time, the card block 26 compresses the spring 25 until the card block 26 is aligned with the next card slot 22. After that, the spring 25 rebounds and pushes the card block 26 to engage with it. When the cross bar 29 drives the moving block 23 to slide upward, the card block 26 repeats The above action drives the cross tube 14 upward when the moving block 23 moves upward, and at the same time stretches the telescopic hose. After the cross tube 14 is adjusted to a suitable height, the cross bar 29 is released. At this time, the spring 25 pushes the block 26 to engage and fix it with the slot 22. Then the water pump 13 is connected to an external power supply to discharge the water inside the water tank 12 into the interior of the cross tube 14 through the telescopic hose and spray it out through the atomizing nozzle to reduce dust. When it is necessary to adjust it downward after use, the pull button 28 can be pulled to make the pull rod 27 drive the block 26 to separate from the slot 22. At this time, the fixation of the moving block 23 is released, and the moving block 23 can be moved downward, driving the cross tube 14 downward at the same time.
