Description

Technical Field

[0001] The utility model relates to the technical field of blasting dust reduction devices, and particularly relates to a dust reduction device. Background Art

[0002] With the wide application of engineering blasting, the negative effects of controlled blasting have gradually increased. Controlled blasting not only needs to control traditional blasting hazards such as blasting vibration, flying rocks, shock waves, and noise, but also needs to effectively control the dust generated by blasting. Although blasting demolition has many advantages compared with traditional demolition methods such as mechanical demolition, the large amount of dust generated during the blasting process has a serious impact on the surrounding environment, especially in busy urban areas and densely populated residential areas. At present, the methods to reduce the dust generated by blasting are mostly to set up high-pressure pipe networks for spraying water outside the building and hang a large number of small water bags around the blast holes. In actual projects, the above methods have a large workload, are difficult to implement, cannot meet the needs of high efficiency and environmental protection, and the dust reduction effect is not ideal.

[0003] For example, the Chinese utility model patent (CN212673966U) discloses a blasting dust reduction device, which records: "The turntable can be rotated through the sector gear, and then the first conduit can be pushed to rotate through the water tank, so that the nozzle slides in the arc-shaped chute, increasing the spraying range and quickly reducing dust, and the base can be moved, making it more convenient to use", and also records the technical problem that "the existing blasting dust reduction devices mainly reduce dust by spraying water through high-pressure pipe networks or hanging water belts, with a large workload and difficult to implement, and cannot meet the needs of high efficiency and environmental protection".

[0004] To sum up, the following technical problems exist in the prior art: The dust reduction device in the above patent can only swing and spray dust reduction on both sides of the device, while the front, back, upper and lower sides of the device cannot reduce dust, and the application range is limited. Moreover, the bottom surface of the construction section is often uneven, and it is difficult to move only through the roller device.
