[0004] The above scheme has the following problems during implementation: the device installs water pipes and nozzles on each fence, so that the water pipes on each fence can be directly connected to each other for spraying. Moreover, when used for a long time or when there is too much dust, the nozzles are likely to be clogged due to dust, so the nozzles need to be replaced. However, most of the nozzles installed on the fences are installed at the top of the fences, which are at a high position. Workers often need to use climbing tools to remove the nozzles, which is troublesome and dangerous, greatly reducing the practicality of the device. To this end, we provide a spray dust reduction mechanism for road construction to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] like Figure 1 and Figure 2As shown, the utility model provides a technical solution: a spray dust reduction mechanism for road construction, comprising a fence 1, a support frame 2 is installed at one end of the fence 1, a mounting groove 11 is opened on the side of the fence 1 close to the support frame 2, and a water pipe 12 is installed in the mounting groove 11, and a branch pipe 13 is installed equidistantly on the upper side of the water pipe 12, and a dust reduction mechanism for construction environmental protection is installed on the upper side of several groups of branch pipes 13, and the dust reduction mechanism includes a spray assembly 3 for spraying water mist and a lowering assembly 4 for lowering the height of the spray assembly 3, and the spray assembly 3 includes a movable groove 31, and the movable groove 31 is opened At the top of the inner wall of the installation groove 11, a hose 32 is installed in the movable groove 31, and the bottom end of the hose 32 is connected to the branch pipe 13, a connecting pipe 33 is installed at the top of the hose 32, and a nozzle 34 is installed at the top of the connecting pipe 33. The hose 32 can be bent and deformed, so that the nozzle 34 can be better raised and lowered. This structure makes it possible to spray water mist for dust reduction, and makes it more convenient to install spray dust reduction equipment after the fence 1 is installed. A groove 35 is provided on the lower side of the inner wall of the movable groove 31 to provide a space for the hose 32 to bend and deform.

[0022] As an implementation method in this embodiment, Figure 3 and Figure 4 As shown, the lowering component 4 is installed on the side of the fence 1 close to the support frame 2 through the connecting pipe 33. The lowering component 4 includes a connecting block 41 and a locking component 5. The connecting block 41 is fixedly connected to the surface of the connecting pipe 33. The bottom end of the connecting block 41 is connected to a support rod 42. A limiting sleeve 14 is installed on the upper side of one end of the fence 1 close to the support frame 2, and the limiting sleeve 14 is sleeved on the upper side of the support rod 42. In order to make the support rod 42 support the connecting pipe 33 and the nozzle 34 more stably through the connecting block 41, a fixing block 43 is installed on the lower side of one end of the fence 1 close to the support frame 2, and a through hole 44 is penetrated through the top of the fixing block 43. The support rod 42 slides in the through hole 44, and the support rod 42 is limited and locked in the through hole 44 by the locking component 5. This structure makes it possible to move the nozzle 34 down from a high place. In this way, it is more convenient to replace the nozzle 34, which greatly increases the practicality of the device. The locking assembly 5 includes a slide groove 51 and a limit groove 54. The slide groove 51 is arranged on the inner wall of the through hole 44, and a spring 52 is installed on the inner side of the slide groove 51. A limit block 53 is slidably installed at the opening of the slide groove 51, and the inner end of the limit block 53 is against the spring 52. The limit groove 54 is arranged on the surface of the support rod 42, and the limit block 53 is inserted in the limit groove 54. The inner end of the limit block 53 is connected with a pull rod 55, and the outer end of the pull rod 55 extends to the outer wall of the fixed block 43. This structure makes it possible to lock the lower side position of the support rod 42 in the through hole 44, so that the nozzle 34 can be lifted and reinstalled. A handle 56 is installed on the outer end of the pull rod 55 to make it more convenient to operate and pull the pull rod 55.

[0023] It should be noted that the groove 35 can not only store the bent and deformed hose 32, but also provide a larger operating space when the nozzle 34 is disassembled after it is moved down, making disassembly more convenient.

[0024] Working principle: If spray dust reduction is required during construction, just splice several groups of fences 1 together, and then connect several groups of water pipes 12. In this way, water can be transported to the water pipes 12 through the high-pressure water pump at the water source, and then enter the hose 32 through the branch pipe 13, and then enter the connecting pipe 33 from the hose 32. Finally, water mist is sprayed out through the nozzle 34 to reduce construction dust;

[0025] In addition, when the nozzle 34 is blocked and needs to be disassembled, it is only necessary to hold the handle 56 and pull it. The handle 56 drives the pull rod 55, and the pull rod 55 drives the limit block 53 to slide in the slide groove 51 to compress the spring 52. Until the limit block 53 is pulled out of the limit groove 54 and completely moves into the slide groove 51, the support rod 42 will lose its limit and slide downward due to gravity. The connecting pipe 33 and the nozzle 34 will also lose their supporting force and slide downward. At this time, it is only necessary to hold the support rod 42 and move it downward manually, and then the support rod 42 drives the connecting pipe 33 and the nozzle 34 to move slowly downward through the connecting block 41. At the same time, the hose 32 will also bend. When the nozzle 34 slides to the lower side of the movable groove 31 corresponding to the groove 35, the space in the groove 35 can be used to disassemble the nozzle 34, making the operation more convenient, greatly increasing the practicality and convenience of the device.

[0026] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
