[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1-6A dust suppression device for construction projects includes a base 1, a water tank 2 is provided at the top rear portion of the base 1, an angle adjustment mechanism is provided at the top front portion of the base 1, an atomizing spray gun 3 is detachably mounted on the angle adjustment mechanism, the atomizing spray gun 3 is connected to the water tank 2 via a water hose 4, a water pump 5 is connected to the water hose 4, the water pump 5 is fixedly connected to the base 1 and is located between the water tank 2 and the angle adjustment mechanism, an elastic winding mechanism is fixedly provided at the top of the base 1 between the water pump 5 and the angle adjustment mechanism, and the water hose 4 is wound around the elastic winding mechanism. When the device as a whole cannot be moved to the area where dust suppression is required, the atomizing spray gun 3 can be removed separately and operated by hand by a staff member, thereby ensuring the dust suppression effect.

[0025] In this embodiment, the angle adjustment mechanism includes an electric rotating platform 6, a support base 7, and a mounting base. The electric rotating platform 6 is fixedly connected to the top of the base 1, the support base 7 is fixedly connected to the rotating table at the top of the electric rotating platform 6, and the support base 7 can rotate with the rotating table. The top rear portion of the support base 7 is hinged to the bottom rear portion of the mounting base. The top front portion of the support base 7 is fixedly connected to a hydraulic telescopic rod 8. The bottom front portion of the mounting base is provided with a strip slide extending along the length direction of the mounting base. The two side walls of the strip slide are penetrated by strip slide holes 9. The top of the hydraulic telescopic rod 8 is fixedly connected to a sliding shaft 10. The two ends of the sliding shaft 10 are respectively slidably installed in the strip slide holes 9 on both sides. The atomizing spray gun 3 can be detachably installed in the mounting base. By controlling the lifting and lowering of the hydraulic telescopic rod 8, the sliding shaft 10 can slide relatively along the strip slide hole 9, thereby driving the mounting base to complete the vertical angle adjustment with the hinge point with the support base 7 as the axis.

[0026] In this embodiment, the mounting seat includes a base plate 11, and the top two sides of the base plate 11 are fixedly connected with arc-shaped side plates 12 respectively. The strip slide and the strip slide hole 9 are both arranged on the base plate 11, and the atomizing spray gun 3 is located between the two arc-shaped side plates 12. The top of the base plate 11 is provided with a T-shaped slide, and the front end of the T-shaped slide is open. The bottom end of the atomizing spray gun 3 is provided with a T-shaped slider 13, and the T-shaped slider 13 is slidably installed in the T-shaped slide. The rear end of the T-shaped slider 13 is fixedly connected with a clamping block 14, and the clamping block 14 is an extension of the bottom end portion of the T-shaped slider 13. The rear end of the T-shaped slide is provided with a The insertion hole that cooperates with the clamping block 14 is an extension of the bottom part of the T-shaped slide groove. The top of the insertion hole is provided with a mounting hole. The mounting hole is vertically arranged and its bottom is connected to the insertion hole. A clamping column 15 is slidably installed in the mounting hole. The top of the clamping column 15 is fixedly connected with a cover plate. The part of the clamping column 15 located between the cover plate and the base plate 11 is provided with a reset spring 16. The top of the reset spring 16 is fixedly connected to the cover plate, and the bottom end of the reset spring 16 is fixedly connected to the upper surface of the base plate 11. The clamping block 14 is provided with a clamping hole 17 that cooperates with the clamping column 15.

[0027] When the atomizing spray gun 3 needs to be installed on the mounting seat, the T-shaped slider 13 at the bottom end of the atomizing spray gun 3 can be installed from the open end of the T-shaped slide groove, and the atomizing spray gun 3 can be slid backward as a whole, and then the clamping column 15 is pulled up to allow the clamping block 14 to smoothly enter the insertion hole. At this time, the clamping hole 17 on the clamping block 14 is aligned with the mounting hole, and finally the clamping column 15 is loosened. The clamping column 15 is inserted downward into the clamping hole 17 under the action of the return spring 16 to achieve clamping and fixing; when the atomizing spray gun 3 needs to be disassembled for use, it is only necessary to pull up the clamping column 15 and slide the atomizing spray gun 3 forward out of the mounting seat.

[0028] In this embodiment, in order to facilitate the installation of the atomizing spray gun 3, the bottom surface of the clamping column 15 is a slope that gradually slopes downward from the side close to the T-shaped slider 13 to the side away from the T-shaped slider 13. During the installation of the atomizing spray gun 3, when the clamping block 14 slides backward, the inclined surface at the bottom end of the clamping column 15 can automatically push the clamping column 15 to move upward, thereby eliminating the need to manually pull the clamping column 15 and making installation easier.

[0029] In this embodiment, a handle 18 is fixedly connected to the rear portion of the top end of the atomizing spray gun 3 so that a worker can hold the atomizing spray gun 3 to perform dust reduction operations.

[0030] In this embodiment, the elastic winding mechanism includes a fixed shaft 19, which is fixed to the base 1 through a fixed bracket 20. A winding drum 21 is rotatably mounted on the fixed shaft 19, and a spiral spring 22 is installed between the winding drum 21 and the fixed shaft 19. The winding drum 21 is a hollow structure, and the spiral spring 22 is located inside the winding drum 21. One end of the spiral spring 22 is fixedly connected to the inner side wall of the winding drum 21, and the other end is fixedly connected to the side wall of the fixed shaft 19. The water hose 4 is wound on the winding drum 21. When the staff uses the handheld atomizing spray gun 3, the winding drum 21 can be unwound by pulling the water hose 4, thereby increasing the usable length of the water hose 4 so that the atomizing spray gun 3 can be moved to an area farther away from the base 1 for use. When the water hose 4 stops being pulled, the winding drum 21 can automatically rewind the water hose 4 under the action of the spiral spring 22.

[0031] In this embodiment, a transparent observation window 23 is provided on the side wall of the water tank 2, which can facilitate the staff to monitor the water level in the water tank 2 in real time and perform water replenishment operations in time.

[0032] In this embodiment, a plurality of universal wheels 24 with brake pads are provided at the bottom end of the base 1 .

[0033] In this embodiment, a push handle 25 is fixedly connected to the rear of the base 1 to facilitate staff to push the device to move.

[0034] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
