Description

Technical Field

[0001] The utility model relates to the technical field of dust prevention, and more specifically, to a dust prevention device for engineering buildings. Background Art

[0002] A construction dust control device is a device designed to control the dust generated during construction at a construction site, protect the environment, and reduce the impact on the health of surrounding residents and construction workers. These devices are usually used in places where dust is easily generated, such as earthworks, demolition operations, and construction material processing.

[0003] In the existing technology, firstly, some devices will not be able to effectively control the size of the dust hopper entrance, which may result in the inability to adjust the amount of dust-containing air sucked in according to actual needs. Without the position control of the movable sealing plate, dust may flow in reverse, reducing the dust prevention effect and causing more dust to escape. Secondly, some devices will find it difficult to achieve stable connection of the connecting components, which may result in loose connection and affect the normal operation of the equipment. The snap-in action will become cumbersome, reducing operating efficiency and prolonging installation and maintenance time. Finally, some devices will find it difficult to achieve rotational adjustment of the snap-in rod, which may result in the snap-in rod being unable to reach the correct position and affecting the performance of the equipment. Without a stabilizing spring and a guide block, the stability and guidance of the snap-in rod will be affected, which may result in unstable operation or failure of the equipment.
