Description

Technical Field

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

[0002] Construction refers to the construction activities of various buildings and structures in the field of construction engineering. In the process of construction, especially earthwork, transportation of construction materials, dust accumulation, building demolition and other links, a large amount of floating dust may be stirred up, which will not only pollute the air and affect the health of construction workers, but also cover the surface of vegetation, affecting vegetation photosynthesis and polluting water bodies. Therefore, dust suppression equipment is needed to suppress the floating dust in construction.

[0003] A conventional dust suppression device, such as a dust suppression device for construction disclosed in application number CN202321784314.6, includes a base and a mounting seat, a roller is installed at the lower end of the base, a motor is installed in the base, a cylinder is fixedly installed at the upper end of the base, and a circular shaft is rotatably connected in the cylinder; a water tank is installed at the upper end of the mounting seat, a water pipe is fixedly installed on the lower end side wall of the water tank, a water spray head is fixedly installed at the outer end of the water pipe, and a power supply and an air pump are fixedly installed on the outer side of the lower end of the mounting seat; the lower end of the circular shaft is connected to the output end of the motor, and the upper end of the circular shaft is connected to the lower end of the mounting seat.

[0004] When the above technical solution is actually used, the user can start the motor to rotate the circular shaft, and the circular shaft rotates with the mounting base, so that the water tank can rotate accordingly, thereby increasing the spraying range and the dust reduction range. Since the water tank is used to store water, when the water tank is full of water, its weight is very heavy. If the water tank is driven to rotate by the motor at this time, the motor load is too large, which will have an adverse effect on the life of the motor and the circular shaft, so there is still room for improvement.
