Problems solved by technology

[0002] Dust pollution on construction sites has a great impact on the city environment. The coverage of traditional spray devices is adjusted by manually changing the direction of the spray tube or by changing the power of the fan in the spray tube through a complex control system to change the spray range. The system is in Poor stability and short lifespan in dusty and humid environment

Embodiment 1

[0021] see Figure 1-4 , in an embodiment of the present invention, a construction dust suppression device includes a car body 1 and a spray tube 2; a fan 16 is arranged in the spray tube 2, and atomizing nozzles 8 distributed in a circle are arranged at the opening of the front end of the spray tube 2 The two sides of the spray tube 2 are connected with the turret 4 through the rotating shaft 3, and the bottom of the turret 4 is fixedly connected with the support shaft 5, and the support shaft 5 extends into the car body 1 and is connected with the car body 1 in rotation; the support shaft 5. The output shaft of the drive motor 7 is connected to the first transmission gear set 6, and the drive motor 7 drives the turret 4 to rotate through the support shaft 5, so as to realize the circular motion of the spray tube 2 and achieve circular spraying and dust reduction.

[0022] The atomizing nozzle 8 is connected with an annular pipe 9, the annular pipe 9 is connected with a hose ...

Embodiment 2

[0024] The difference between this embodiment and Embodiment 1 is that the spray tube 2 is connected with an up and down swing mechanism, and the up and down swing mechanism includes a passive gear 18 sleeved on the rotating shaft 3, and the driven gear 18 is engaged with a rack plate 19. The lower end of the plate 19 is fixedly connected with a rectangular frame 20, the rectangular frame 20 is nested with an eccentric column 21, the eccentric column 21 is connected with a turntable 23, and the turntable 23 is rotatably connected with the turret 4 through a horizontal shaft 27; the horizontal shaft 27 passes through the second The transmission gear set 28 is connected with a vertical shaft 29, the vertical shaft 29 runs through the turret 4 and extends to the bottom of the turret 4, the lower end of the vertical shaft 29 is fixedly connected with a rolling gear 30, and the rolling gear 30 is toothed with a rack ring 31, The rack ring 31 is fixedly connected with the car body 1;...

Abstract

The invention discloses a dust falling device for construction engineering. The dust falling device comprises a car body and a spray barrel, wherein a rotating bracket is rotationally connected with the two sides of the spray barrel through a rotating shaft, and a supporting shaft is fixedly connected with the bottom of the rotating bracket and connected with an output shaft of a drive motor through a first transmission gear set; and a vertical swing mechanism is connected with the spray barrel. By means of the rotating bracket, the supporting shaft and the vertical swing mechanism comprisinga driven gear, a rack plate, a rotating disc, a rolling gear and a rack ring, vertical swing motion is performed while the spray barrel moves circumferentially, a larger spray coverage range is realized, and the dust falling effect is improved; a moving block, a radial groove, a screw rod and a regulating wheel are arranged, so that the vertical swing range of the spray barrel is changed, meets the requirement of different spray scenes for the spray coverage area and has good adaptability.

Description

technical field [0001] The invention relates to the field of construction engineering equipment, in particular to a construction engineering dust suppression device. Background technique [0002] Dust pollution on construction sites has a great impact on the city environment. The coverage of traditional spray devices is adjusted by manually changing the direction of the spray tube or by changing the power of the fan in the spray tube through a complex control system to change the spray range. The system is in Poor stability and short lifespan in dusty and humid environment. The present application provides a mechanical adjustment mechanism to stably realize the adjustment of spray coverage. Contents of the invention [0003] The purpose of the present invention is to provide a construction engineering dust suppression device to solve the problems raised in the above background technology. [0004] To achieve the above object, the present invention provides the following ...
