[0031] To solve this technical problem, this utility model provides a new type of dust removal device for engineering entrances and exits, which is applied to dust removal at engineering entrances and exits.

[0038] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings.

[0039] Embodiment 1:

[0040] Please refer to Figure 1 - Figure 3 , a novel dust reduction device for the engineering entrance, which includes:

[0041] A dust reduction frame 1, the dust reduction frame 1 includes a spray pipe 5. A plurality of nozzles 6 are fixedly distributed along the length direction at the lower end of the spray pipe 5. Connecting vertical pipes 7 are vertically arranged at both ends of the spray pipe 5, and the end of the spray pipe 5 is connected to the connecting vertical pipe 7 through a connecting pipe 8. It can be seen that water source is transported into the spray pipe 5 through the connecting vertical pipe 7 and the connecting pipe 8, and can be sprayed out through the nozzles 6, thereby achieving the dust reduction effect. Among them, the connecting pipe 8 is a corrugated pipe, so that the spray pipe 5 can move up and down and can maintain the connection state with the connecting vertical pipe 7, so that the height position of the spray pipe 5 can be adaptively adjusted according to the needs.

[0042] A liquid supply pipe 2 is arranged at the end of the dust reduction frame 1. The liquid supply pipe 2 is fixedly connected to the connecting vertical pipe 7, and the liquid supply pipe 2 is internally connected to the connecting vertical pipe 7.

[0043] Adjusting frame 3 is arranged at a position on one side of the end of the dust reduction frame 1. The adjusting frame 3 includes a fixed frame 9, and the fixed frame 9 is arranged parallel to the connecting vertical pipe 7. On the side of the fixed frame 9 close to the connecting vertical pipe 7, a lifting frame 10 is arranged vertically. The upper end of the lifting frame 10 is buckled and connected to the end of the spray pipe 5, and the lower end of the lifting frame 10 is slidably connected to the fixed frame 9. Further, a limiting chute 13 is vertically opened on the side of the fixed frame 9 close to the dust reduction frame 1, and the lower end of the lifting frame 10 is vertically slidably connected to the limiting chute 13. A limiting knob 14 is arranged on the side surface of the lower end of the lifting frame 10 for limiting the movement of the lifting frame 10. It can be seen that the support for the lifting frame 10 can be realized through the fixed frame 9, the guiding and limiting of the movement of the lifting frame 10 can be realized through the limiting chute 13, and through the buckling of the upper end of the lifting frame 10 and the end of the spray pipe 5, the spray pipe 5 can be driven to move up and down when the lifting frame 10 moves up and down, and the limiting of the lifting frame 10 after movement can be realized by tightening the limiting knob 14 after each movement of the lifting frame 10.

[0044] Connecting pieces are arranged at the upper and lower ends of the side surface of the fixed frame 9. The connecting pieces include connecting piece one 11 and connecting piece two 12. Connecting piece one 11 is fixedly connected to the upper part of the side surface of the fixed frame 9, and connecting piece two 12 is fixedly connected to the lower part of the side surface of the fixed frame 9. The connecting vertical pipe 7 is located inside connecting piece one 11 and connecting piece two 12, and the lifting frame 10 is also located inside connecting piece one 11. Through connecting piece one 11 and connecting piece two 12, the connection between the connecting vertical pipe 7 and the fixed frame 9 can be realized, so that the fixed frame 9 can support the dust reduction frame 1, and through connecting piece one 11, the guiding and limiting of the upper part of the lifting frame 10 can be realized, reducing the shaking phenomenon of the lifting frame 10.

[0045] Embodiment 2:

[0047] Through the above structural design, the quick connection between the adjusting frame 3 and the dust reduction frame 1 can be realized, and combined with the buckling of the upper part of the lifting frame 10 and the spray pipe 5, the integral separation of the adjusting frame 3 from the dust reduction frame 1 can also be realized.

[0048] Embodiment 3:

[0049] The novel engineering entrance and exit dust reduction device provided in Embodiment 1 is further optimized. Specifically, as Figure 4As shown, a stabilizing frame 4 is vertically arranged inside the dust suppression frame 1, and the stabilizing frame 4 is used for auxiliary support when the spray pipe 5 is raised or lowered. Specifically, the stabilizing frame 4 includes a connecting frame 15, and a connecting buckle seat 16 is fixedly connected to the upper end of the connecting frame 15. The connecting frame 15 is buckled and connected to the end of the spray pipe 5 through the connecting buckle seat 16. The lower part of the connecting frame 15 is slidably connected to a guide seat 17, and the guide seat 17 is plug-connected with the connecting piece 11.

[0050] Through the above-mentioned structural design, the connecting frame 15 is connected to the spray pipe 5 through the connecting buckle seat 16 at the upper end, and the lower part of the connecting frame 15 can be limited by the guide seat 17, so that when the spray pipe 5 is raised or lowered, the movement of the spray pipe 5 is limited by the connecting frame 15, thereby reducing the occurrence of shaking of the spray pipe 5.
