Description

Technical Field

[0001] The utility model relates to the technical field of road construction equipment, and specifically relates to a dust suppression device for road construction. Background Art

[0002] During the process of municipal construction, the current dust control is a very important process.

[0003] The existing road detection and dust suppression equipment usually adds a water mist spraying device on the construction site fence. This device is usually composed of a main pipe, several shunt pipes and several atomizing nozzles. The main pipe is usually connected to a water pump or a water pipe. After the main pipe is filled with water, the water automatically enters each shunt pipe through water pressure, and then sprays out from the atomizing nozzles. However, this device has a simple structure, which makes the water pressure of the shunt pipes closer to the water inlet of the main pipe larger, and the water pressure of the shunt pipes far from the water inlet of the main pipe smaller. As a result, the water mist sizes sprayed out by each part of the entire dust suppression device are different, and the spraying angle of the water mist cannot be adjusted. The arrangement of the shunt pipes also fixes the spraying angle, resulting in the inability to adjust the direction of the water mist sprayed out by the shunt pipes. Therefore, a road dust suppression device is needed in which the water pressure of each shunt pipe on the dust suppression device is the same and the sprayed water can also be adjusted in angle.

[0026] The following further describes the present invention with reference to the embodiments.

[0027] Refer to Figures 1-4, A dust suppression device for road construction in this embodiment includes a main pipe 1. A branch pipe 2 is fixedly installed on the outer surface of the main pipe 1. A water pressure controller 3 is fixedly installed on the outer surface of the branch pipe 2. The water pressure controller 3 includes a pressure motor 31, a threaded shaft 32, a first spring 33, a second spring 34, a piston 35, a baffle 36, a connecting pipe 37, a pressure sensor 38, and a top block 39. A spraying angle adjusting mechanism 4 is fixedly installed at the top of the branch pipe 2. The spraying angle adjusting mechanism 4 includes a fixing plate 41, a rotating motor 42, a rotating shaft 43, a main gear 44, a driven gear 45, a rotating cylinder 46, and an atomizing nozzle 47.

[0028] As Figure 3 and 4 shown, both the pressure motor 31 and the pressure sensor 38 are controlled by an external control software, and can freely adjust the water pressure in each branch pipe 2 on the main pipe 1.

[0029] As Figure 3 and 4 shown, the right side of the pressure motor 31 is fixedly connected to the outer surface of the connecting pipe 37. The output end of the pressure motor 31 is fixedly connected to the outer surface of the threaded shaft 32 through a speed reducer. The outer surface of the threaded shaft 32 is threadedly connected to the inner surface of the top block 39.

[0030] As Figure 3 and 4 shown, the bottom of the top block 39 is fixedly connected to one end of the first spring 33. The other end of the first spring 33 is fixedly connected to the right side of the piston 35. The outer surface of the piston 35 is slidably connected to the inner surface of the connecting pipe 37.

[0031] As Figure 3 shown, the inner wall of the connecting pipe 37 is fixedly connected to the outer surface of the baffle 36. The left side of the piston 35 is fixedly connected to one end of the second spring 34. The other end of the second spring 34 is fixedly connected to the inner wall of the connecting pipe 37. The left side of the pressure sensor 38 is communicated with the outer surface of the connecting pipe 37.

[0032] As Figure 1 and 2 shown, the top of the fixing plate 41 is fixedly connected to the bottom of the rotating motor 42. The output end of the rotating motor 42 is fixedly connected to the outer surface of the rotating shaft 43 through a speed reducer.

[0033] As Figure 1 and 2 shown, the outer surface of the rotating shaft 43 is fixedly connected to the inner surface of the main gear 44. The outer surface of the main gear 44 is meshed with the outer surface of the driven gear 45. The inner surface of the driven gear 45 is fixedly connected to the outer surface of the rotating cylinder 46.

[0034] As Figure 1 and 2As shown, the top end of the rotating cylinder 46 is in communication with the bottom end of the atomizing nozzle 47. The inner surface of the fixing plate 41 is fixedly connected to the outer surface of the branch pipe 2, and the top of the fixing plate 41 is rotatably connected to the bottom of the rotating cylinder 46.

[0035] As Figure 1 and 2 shown, the rotating cylinder 46 is fixedly mounted on the atomizing nozzle 47 at a certain angle.

[0036] In summary, the dust suppression device for road construction can install the water pressure controller 3 on the branch pipe 2, and then the main pipe 1 is filled with water. The water flow first enters the communicating pipe 37, and then flows into the other end of the communicating pipe 37 through the gap between the communicating pipe 37 and the piston 35. The pressure sensor 38 measures the water pressure on the other side of the communicating pipe 37. When the water pressure is too high or too low, the pressure sensor 38 will send a signal to the pressure motor 31. The pressure motor 31 drives the threaded shaft 32 to rotate. The threaded shaft 32 drives the first spring 33 to move through the top block 39. The first spring 33 drives the piston 35 to move up and down to adjust the gap between the piston 35 and the baffle 36 to control the water flow rate, thereby controlling the water pressure in the branch pipe 2. When the water pressure of all the branch pipes 2 is controlled to the specified value, the water flow will first pass through the rotating cylinder 46 and then be sprayed out from the atomizing nozzle 47. When the spraying angle of the atomizing nozzle 47 is different, the rotating motor 42 drives the rotating shaft 43 to rotate. The rotating shaft 43 drives the driven gear 45 to rotate through the main gear 44. The driven gear 45 drives the atomizing nozzle 47 to rotate through the rotating cylinder 46 to adjust the angle of the atomizing nozzle 47 to prevent the water mist sprayed by the atomizing nozzle 47 from failing to cover the dust.
