There are a large number of substances harmful to the human body in these dusts, which will affect the health of the staff. Therefore, a dust removal device is needed to deal with it.

[0003] The air inlets of existing dust removal devices are relatively small, and most of them cannot perform preliminary screening on dust before collecting it. The utility model patent with the publication number of CN219425215U discloses an efficient dust removal device for building civil engineering construction. The device includes a bottom plate, a shock absorber is fixedly connected to the top of the bottom plate, a waste collection box is fixedly connected to the top of the shock absorber, a first air inlet is arranged on one side of the box body, and a filter screen is arranged inside the first air inlet. This dust removal device can reduce the vibration generated during the operation and movement of the device through the setting of the shock absorber, which can ensure the stability and safety of the device. By setting the filter screen, preliminary screening of dust can be carried out, and larger impurity wastes can be blocked to ensure the subsequent dust removal effect. However, the air inlet of the above patent can only intake air in one direction, and the air inlet is small. Due to the too small contact area with the air, the problem of too low dust removal efficiency still exists. Summary of the Invention

The plurality of dust suction holes 302 all lead to the dust suction cavity 301, and a filter screen 304 is arranged in each dust suction hole 302; the dust suction holes 302 are strip-shaped and extend from one end of the hollow roller body 300 to the other end; one end of the hollow roller body 300 is provided with an air outlet pipe 310, and the port of the air outlet pipe 310 extends outside the support plate 2 on this side. The dust suction pump 309 is fixedly installed on the support plate 2 on the side where the air outlet pipe 310 is provided, and its air suction port is hermetically connected to the outlet end of the air outlet pipe 310. The roller body drive mechanism includes a drive motor 305, a drive gear 306 and a toothed ring 307 fixed to one end of the hollow roller body 300.

[0027] The embodiment provides an efficient dust removal device for civil engineering, as Figures 1 to 4As shown in the figure, the collection component 4 includes a collection chamber 400. The top of the collection chamber 400 is open, and the chamber opening is facing directly below the hollow roller 300. A dust removal brush body 401 is provided on one side of the chamber opening. The top surface of the dust removal brush body 401 is an arc surface or an inclined surface that matches the hollow roller 300 and is in contact with the surface of the hollow roller 300. The direction in which the dust removal brush body 401 is arranged is the same as the rotation direction of the hollow roller 300.

[0028] The embodiment provides an efficient dust removal device for civil engineering. As Figure 1 shown, the sensing and control mechanism 5 includes a humidity sensor 500 and a solenoid valve 501.

The driving motor 305 drives the power rod 308 to rotate, drives the driving gear 306 to rotate, and drives the toothed ring 307 to rotate through meshing transmission, thereby driving the roller 300 to rotate. When the roller 300 rotates past the top of the collection chamber 400, the dust removal brush body 401 brushes the dust on the surface of the hollow roller 300 and drops it into the collection chamber 400.

[0030] During the entire dust removal process, the humidity change in the environment is monitored through the humidity sensor 500. When it rains, the humidity sensor 500 transmits a signal to the solenoid valve 501, and the solenoid valve 501 controls the dust suction pump 309 and the driving motor 305 to stop working.

[0031] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
