Description

Technical Field

[0001] This utility model belongs to the technical field of dust removal devices, and in particular relates to a dust removal device for construction sites. Background Technology

[0002] Construction refers to the production activities during the implementation phase of a project. It is the process of building various types of buildings, or the process of turning the lines on the design drawings into physical objects at a designated location. The place where construction work is carried out is called the "construction site" or "construction site". On the construction site, various construction operations will generate a certain amount of dust. In order to avoid dust, dust removal devices are usually set up on the construction site.

[0003] Although there are various types of dust removal devices available today, some problems still exist. For example, most current dust removal devices use water mist dust removal, which involves spraying water mist into the air through nozzles to remove dust. However, since most nozzles on current dust removal devices are fixed, that is, fixed to a support structure, their angle cannot be changed. If it is necessary to adjust the spray angle, it needs to be adjusted manually, resulting in a limited dust removal range. Moreover, adjusting the dust removal range requires a lot of manpower and is cumbersome to operate. Utility Model Content

[0025] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] This utility model embodiment provides a dust removal device for construction sites, such as... Figures 1-5 As shown, it includes: a support rod 1, a height adjustment mechanism 2, and a dust removal mechanism 3;

[0027] The height adjustment mechanism 2 is connected to the support rod 1, and the dust removal mechanism 3 is connected to the height adjustment mechanism 2;

[0028] The height adjustment mechanism 2 includes a fixed base 21 and a support rod 22. The fixed base 21 is fixed to the top of the support rod 1, and the support rod 22 is slidably connected to the top of the support rod 1 and slidably connected to the fixed base 21.

[0029] The dust removal mechanism 3 includes a docking seat 31, a linkage rod 32, a connecting cylinder 33, and an atomizing nozzle 34. The docking seat 31 is fixed to the top of the support rod 22, the linkage rod 32 is rotatably connected to one side of the docking seat 31, the connecting cylinder 33 is fixed to one end of the linkage rod 32, and the atomizing nozzle 34 is mounted on the connecting cylinder 33.

[0030] It should be noted that most existing dust removal devices use water mist dust removal, which involves spraying water mist into the air through nozzles. However, since most nozzles on these devices are fixed to a support structure, their angle cannot be changed. Adjusting the spray angle requires manual intervention, resulting in a limited dust removal range and cumbersome operation due to the high manpower required. To address this issue, this solution incorporates a height adjustment mechanism 2 and a dust removal mechanism 3. The atomizing nozzle 34 in the dust removal mechanism 3 atomizes the liquid into the air, achieving dust removal. During dust removal, a limiting cylinder 36 and other structures work together to move the atomizing nozzle 34 up and down on the docking seat 31, increasing the atomization dust removal range and achieving high-efficiency dust removal. This effectively solves the technical problem. Furthermore, the height adjustment mechanism 2 allows operators to quickly adjust the dust removal mechanism 3 to the appropriate height for use, making it simple, efficient, and time-saving.

[0031] Specifically, in this embodiment, the solution mainly includes a support rod 1, a height adjustment mechanism 2, and a dust removal mechanism 3. In use, the dust removal mechanism 3 is first adjusted to an appropriate height by the height adjustment mechanism 2, and then the external guide pipe is connected to the pipe connector 35. The liquid is then introduced into the connecting cylinder 33 and sprayed out through the atomizing nozzle 34 to achieve a dust removal effect. During dust removal, the limiting cylinder 36 rotates and drives the driven seat 37 and the driven rod 38 to move synchronously, thereby driving the linkage rod 32 to rotate, so as to maximize the dust removal angle.

[0032] In a further preferred embodiment of this utility model, such as Figures 1-5 As shown, the dust removal mechanism 3 also includes a pipe connector 35, which is disposed on the side wall of the linkage rod 32 and has a cavity inside the linkage rod 32. The connecting cylinder 33 and the pipe connector 35 are connected through the cavity of the linkage rod 32, and the outer wall of the pipe connector 35 is provided with threads.

[0033] In this embodiment, the external guide pipe can be quickly connected to the dust removal mechanism 3 via the pipe connector 35.

[0034] In a further preferred embodiment of this utility model, such as Figures 1-5 As shown, the dust removal mechanism 3 also includes a limiting cylinder 36, a driven seat 37, a driven rod 38, and a micro servo motor 39;

[0035] The limiting cylinder 36 is rotatably connected inside the docking seat 31, and a special-shaped groove is provided on the side wall of the limiting cylinder 36. One side of the driven seat 37 is rotatably connected to the linkage rod 32, and the driven rod 38 is provided on the other side of the driven seat 37. One end of the driven rod 38 is slidably engaged in the special-shaped groove. The micro servo motor 39 is fixed on the docking seat 31, and the output shaft of the micro servo motor 39 is coaxially connected to the limiting cylinder 36.

[0036] In this embodiment, the micro servo motor 39 drives the limiting cylinder 36 to rotate, thereby causing one end of the driven rod 38 to move in the irregular groove and simultaneously drive the driven seat 37 to move in the same direction. The driven seat 37 then drives the linkage rod 32 to rotate on the docking seat 31.

[0037] In a further preferred embodiment of this utility model, such as Figures 1-5 As shown, the atomizing nozzle 34 is available in various models, and a threaded tube is provided at the mating end of the connecting cylinder 33 and the atomizing nozzle 34. The atomizing nozzle 34 is detachably connected to the connecting cylinder 33 through the threaded tube.

[0038] In this embodiment, staff can select the appropriate model of atomizing nozzle 34 for use based on the actual situation.

[0039] In a further preferred embodiment of this utility model, such as Figures 1-5 As shown, the height adjustment mechanism 2 also includes a toothed groove 23, an adjusting gear 24, a driven gear 25, a transmission rod 26, and a driving gear 27;

[0040] The tooth groove 23 is set on the side wall of the support rod 22. The adjusting gear 24 is rotatably connected in the fixed seat 21 and meshes with the tooth groove 23. The adjusting gear 24 is coaxially fixed on one side of the driven gear 25. The transmission rod 26 is rotatably connected in the fixed seat 21. The driving gear 27 is coaxially fixed on the transmission rod 26 and meshes with the driven gear 25.

[0041] In this embodiment, the driving gear 27 drives the driven gear 25 to mesh and move together, which in turn drives the adjusting gear 24 to rotate. The adjusting gear 24 then drives the support rod 22 to move together, thereby achieving rapid adjustment of the height of the dust removal mechanism 3.

[0042] In a further preferred embodiment of this utility model, such as Figures 1-5 As shown, the height adjustment mechanism 2 also includes a ratchet 28, a pawl 29, and a leaf spring 210. The ratchet 28 is coaxially fixed on the transmission rod 26 and located outside the fixed seat 21. One end of the pawl 29 is rotatably connected to the fixed seat 21, and the other end abuts against the edge of the ratchet 28. One end of the leaf spring 210 is fixed to the fixed seat 21, and the other end abuts against the pawl 29.

[0043] In this embodiment, the ratchet 28 is limited by the pawl 29 to prevent the transmission rod 26 from rotating and causing the height of the support rod 22 to change.
