DETAILED DESCRIPTION

[0017] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] like Figure 1 and 2 As shown, this embodiment discloses a dust reduction and cleaning machine for a construction site, including a trolley 1 on which a fan 2 and a dust collecting device 3 are provided.

[0019] The fan 2 is located at the front of the trolley 1, and the air outlet at the top of the fan 2 is connected to the dust collecting device 3 through a flexible air duct 4. A trumpet-shaped dust suction hopper 5 is arranged on the front air inlet of the fan 2. A drive motor 6 is arranged at the rear of the fan 2. The drive motor 6 is connected to the fan 2 by power, and the drive motor 6 is connected to the trolley 1 through a support frame 7.

[0020] The dust collecting device 3 is located at the rear of the trolley 1. The dust collecting device 3 includes a box body 301, which is mounted on the trolley 1 through a plurality of legs 302. A detachable top cover 303 is provided on the top of the box body 301, and the top cover 303 is connected to the flexible air duct 4. A constriction 304 is provided at the bottom of the box body 301, and a dust bag 305 is sleeved on the constriction 304. The dust bag 305 is fixed to the constriction 304 through a hoop. A bracket 306 is fixed in the box body 301, and a limiting groove 307 is provided on the bracket 306. A water basin 308 is provided in the limiting groove 307.

[0021] In this embodiment, an air guide tube 309 is fixed to the bottom of the top cover 303 , an upper end of the air guide tube 309 corresponds to the connection port of the flexible air duct 4 , and a lower end of the air guide tube 309 extends to the top of the water basin 308 .

[0022] In this embodiment, a protective net 8 is provided on the port of the dust hopper 5 to prevent larger foreign matter from entering the fan 2.

[0023] In this embodiment, a wire take-up device 9 is provided at the rear of the trolley 1 , and electric wires are wound around the wire take-up device 9 . The electric wires are used to supply power to the driving motor 6 .

[0024] like Figure 3 As shown, in this embodiment, the support frame 7 includes a lower pillar 701, a gear housing 702 is arranged on the top of the lower pillar 701, a vertically arranged rotating shaft 703 is arranged in the gear housing 702, the rotating shaft 703 is rotatably connected in the gear housing 702 through a bearing assembly, and the upper end of the rotating shaft 703 extends to the outside of the gear housing 702 and is connected to the upper pillar 704, the driving motor 6 is mounted and fixed on the upper pillar 704, a turbine 705 is fixed on the rotating shaft 703, a worm 706 is meshed on one side of the turbine 705, the worm 706 is rotatably connected in the gear housing 702, and one end of the worm 706 is exposed on the outside of the gear housing 702 and is connected to the handwheel 707.

[0025] The action process of the utility model is as follows:

[0026] First, the driving motor 6 is powered on to drive the fan 2 to rotate. The negative pressure wind generated by the fan 2 sucks the dust in the air into the dust collecting device 3 through the trumpet-shaped dust hopper 5. The dust accompanied by the negative pressure wind first hits the water basin 308 through the air guide tube 309, and a part of it is absorbed by the water in the water basin 308. The additional dust enters the dust bag 305 along with the negative pressure wind, and the dust bag 305 can filter and collect the dust.

[0027] When the direction of the dust hopper 5 needs to be adjusted, the hand wheel 707 can be rotated, and the hand wheel 707 drives the upper support 704 to rotate through the turbine 705 and the worm 706. The upper support 704 can adjust the direction of the dust hopper 5 during the rotation process.

[0028] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
