[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1-4As shown, the utility model provides an embodiment: a conveniently adjustable dust removal device for construction, including a base plate 1, the base plate 1 is used for support, a chassis 2 is arranged on the top of the base plate 1, the chassis 2 is used for support and adjustment, a protective cylinder 3 is fixedly connected to the top of the chassis 2, a lifting column is slidably arranged in the protective cylinder 3, a top plate 4 is arranged on the top of the lifting column, the top plate 4 provides support, a fixed box 5 is fixedly connected to the top of the top plate 4, the fixed box 5 provides support, a nozzle 53 is arranged on the top of the fixed box 5, and the nozzle 53 can spray water for dust removal.

[0028] Preferably, a lifting structure for driving the lifting column to rise and fall is provided in the protective cylinder 3. Specifically, the lifting column can be set as a rack, and a gear that meshes with the rack is rotatably provided at the bottom of the protective cylinder 3. The gear can be driven by turning a crank or by a motor to rotate, thereby driving the lifting column and the top plate 4 on the top of the lifting column to rise and fall.

[0029] The top of the bottom plate 1 is provided with a rotating assembly, which includes a limiting groove 23, which is opened at the top of the bottom plate 1 and is located below the chassis 2. There are multiple groups of limiting grooves 23, and the multiple groups of limiting grooves 23 are all opened at the top of the bottom plate 1 near the bottom of the chassis 2. The multiple groups of limiting grooves 23 are arranged in a circle, and the bottom end of the chassis 2 is slidably connected to the limiting ball 22, and the limiting ball 22 is elastically connected to the chassis 2 through a spring 21. The limiting ball 22 slides on the inner wall of the limiting groove 23, and the limiting ball 22 is driven to slide by rotating the chassis 2. The limiting ball 22 slides and is squeezed by the bottom plate 1 and then moves upward to squeeze the spring 21. When the direction of the chassis 2 is adjusted, the limiting ball 22 can be reset and slide into the limiting groove 23 by the reverse force of the squeezing of the spring 21, so that the chassis 2 can be limited. The direction of the protective tube 3 and the nozzle 53 can be adjusted by rotating the chassis 2, and the direction of the spray can be conveniently adjusted to adapt to dust points in different directions, thereby improving the dust removal efficiency.

[0030] In this embodiment, the water spraying direction of the nozzle 53 is set to the front side.

[0031] In this embodiment, three nozzles 53 are provided, and the three nozzles 53 are arranged in left and right arrangement at the top of the fixed box 5 and are rotatably connected to the fixed box 5. An adjustment component is provided at the top of the fixed box 5, and the adjustment component includes two support plates 52. The two support plates 52 are respectively provided at positions near the left and right ends of the top of the fixed box 5, and the two support plates 52 are respectively fixedly connected to the outer walls of the two nozzles 53 located at the top of the fixed box 5 near the left and right ends, and a positioning plate 51 is fixedly provided at one end of the front side of the two support plates 52 away from the nozzle 53.

[0032] The adjustment assembly also includes a connecting plate 57 hinged to the two positioning plates 51 respectively, and the other ends of the two connecting plates 57 are hinged to the sliding sleeve 54. The connecting plate 75 can drive the two positioning plates 51, the two support plates 52 and the two nozzles 53 to rotate in opposite directions. At the same time, the nozzle 53 located in the middle position of the top of the fixed box 5 does not rotate, so as to expand the range of the spray so that the spray can cover a wider area, thereby improving the dust removal efficiency. At the same time, due to the setting position of the positioning plate 51, the rotation range of the two nozzles 53 can be increased, so that the spray range is larger and the dust removal efficiency is higher.

[0033] In this embodiment, the two connecting plates 57 , the two supporting plates 52 , and the two positioning plates 51 are all symmetrically arranged with the center line of the fixing box 5 as the axis of symmetry.

[0034] In this embodiment, the top end of the fixed box 5 is located at the rear side of the nozzle 53 and is fixedly connected to two limit blocks 59. The two limit blocks 59 respectively limit the rotation of the two support plates 52 to prevent the support plates 52 from rotating too much and being unable to be pushed back by the connecting plate 57. A positioning frame 55 extending toward the back side of the fixed box 5 is fixedly connected between the two sets of limit blocks 59. A sliding groove 58 is provided at the top end of the positioning frame 55, and a threaded rod 56 is rotatably provided inside the positioning frame 55.

[0035] Preferably, the threaded rod 56 passes through the rear side wall of the positioning frame 55 and is connected to a rotating crank or a motor, as long as it can drive the threaded rod 56 to rotate.

[0036] The ends of the two connecting plates 57 are hinged with the same sliding sleeve 54, and the sliding sleeve 54 can drive the two groups of connecting plates 57 to move. The sliding sleeve 54 is threadedly connected to the threaded rod 56. The threaded connection between the sliding sleeve 54 and the threaded rod 56 can be used to rotate the threaded rod 56 to drive the sliding sleeve 54 to move, so that the two groups of nozzles 53 can be easily adjusted. The sliding sleeve 54 is slidably connected to the inner wall of the sliding groove 58.

[0037] Preferably, a water tank is further provided on the top of the base plate 1 , and a water pipe connected to the three nozzles 53 is provided on the water tank to provide water for the three nozzles 53 .

[0038] Working principle: When in use, the protective tube 3 and the top plate 4 are driven to rotate by rotating the chassis 2, and the limiting ball 22 is driven to slide by the rotation of the chassis 2. At the same time, the limiting ball 22 slides and is squeezed by the bottom plate 1 to move the squeezing spring 21 upward. When the direction of the chassis 2 is adjusted, the limiting ball 22 can be reset and slide into the limiting groove 23 by the reverse force of the squeezing of the spring 21, so that the chassis 2 can be limited, and the direction of the spray can be conveniently adjusted to adapt to dust points in different directions, thereby improving the dust removal efficiency.

[0039] By rotating the threaded rod 56, which is threadedly connected to the sleeve 54, the sleeve 54 can be moved. The movement of the sleeve 54 pulls the connecting plate 57 and the positioning plate 51, and the positioning plate 51 pulls the support plate 52 and the nozzle 53 to rotate. By symmetrically arranging two groups of connecting plates 57, positioning plates 51, support plates 52, and nozzles 53, the two groups of nozzles 53 located at the left and right ends can be rotated in opposite directions, and the nozzle 53 located in the middle of the fixed box 5 does not rotate, thereby expanding the range of the spray and allowing the spray to cover a wider area, thereby improving the dust removal efficiency.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
