Description

Technical Field

[0001] This utility model relates to the field of municipal construction equipment technology, and in particular to a dust suppression device for municipal road construction. Background Technology

[0002] During municipal road construction, processes such as road cutting, excavation, and material loading and unloading inevitably generate a large amount of dust. This dust not only pollutes the air environment but also seriously threatens the health of construction workers. Therefore, adopting effective dust control measures is a necessary step for safe and civilized production at construction sites.

[0003] Currently, water spraying is commonly used for dust suppression at construction sites. The dust suppression devices typically include water trucks and some fixed and mobile spray equipment. However, these existing devices have revealed many shortcomings in actual use. First, the spray head angle of many devices is fixed or has a very limited adjustment range. When facing dust sources at different heights and directions, it is impossible to accurately aim the spray, resulting in low dust suppression efficiency and wasted water resources. Second, some devices rely solely on water pump pressure to spray water, resulting in larger water mist particles that are not effective in suppressing fine dust suspended in the air, and the spray coverage area is also relatively limited. In addition, although some mobile dust suppression devices have a certain degree of flexibility, their nozzle attitude adjustment mechanisms are complex in design and inconvenient to operate, making it difficult to quickly respond to the changing dust suppression needs of construction sites. They suffer from problems such as inflexible adjustment, small spray coverage area, and inability to accurately and efficiently suppress dust.

[0004] Therefore, this utility model proposes a dust suppression device for municipal road construction to address the shortcomings of existing technologies. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0027] Example: Please refer to Figure 1 , Figure 2 and Figure 4As shown, a dust suppression device for municipal road construction includes a support base 314, a spraying mechanism 4, which is vertically mounted on the support base 314, and an adjustment mechanism 3 for adjusting the spraying posture of the spraying mechanism 4. The support base 314 has a rectangular frame structure, and four sets of movable wheels 313 are fixedly installed at the bottom corners of the support base 314. Each set of movable wheels 313 is equipped with a braking mechanism. Handrails 315 are provided on the edge of the support base 314. The support base 314 has slots inside for fixing a water tank 45. The device also includes a movable door 2, which is hinged to the support base 314, allowing the water tank 45 to be removed through the movable door 2. The device also includes a top cover 1, which covers the support base 314. The adjustment mechanism 3 includes... The adjustment mechanism 3 includes a fixed sleeve 31, which is fixedly connected to the top of the upper cover 1. The inner wall of the fixed sleeve 31 is provided with an axial guide groove 34. The adjustment mechanism 3 also includes a telescopic support rod 32, which is slidably inserted into the interior of the fixed sleeve 31. The outer wall of the telescopic support rod 32 is provided with a guide protrusion 33 that matches the axial guide groove 34, ensuring that the telescopic support rod 32 can only move up and down along the axial direction of the fixed sleeve 31. The outer wall of the telescopic support rod 32 is provided with multiple locking holes 35 along the axial direction. The adjustment mechanism 3 also includes a locking pin 36, which can be selectively inserted into any locking hole 35. The adjustment mechanism 3 also includes an adjustment handle 37, which is connected to the locking pin 36 through gear transmission, and is used to drive the locking pin 36 to insert or disengage from the locking hole 35.

[0028] Please refer to Figure 1 , Figure 3 and Figure 5The adjustment mechanism 3 also includes a rotating support 39, which is rotatably connected to the top of the telescopic support rod 32 via a bearing 38. The bearing 38 allows the rotating support 39 to rotate smoothly horizontally around the central axis of the telescopic support rod 32. A rotating handle 310 is fixedly connected to the outer wall of the rotating support 39, allowing the operator to easily rotate the rotating support 39 horizontally by turning the rotating handle 310. The spraying mechanism 4 includes a spray branch pipe 41, which has a multi-segment structure. The spray branch pipe 41 is hinged to the outside of the rotating support 39 via an outer bracket 411 and a hinge 410. This hinged connection allows the spray branch pipe 41 to pitch around the axis of the hinge 410. To adjust and fix the pitch angle, the adjustment mechanism 3 also includes an adjusting screw 311 and a positioning nut 312. One end of the adjusting screw 311 is hinged around the inner wall of the spray branch pipe 41. The other end of 11 passes through the mounting hole on the rotating support 39, and a positioning nut 312 is threaded onto the protruding end. When the pitch angle needs to be adjusted, the operator rotates the positioning nut 312, and the positioning nut 312 moves axially on the adjusting screw 311, thereby changing the extension length of the adjusting screw 311 relative to the rotating support 39. Since the other end of the adjusting screw 311 is hinged to the spray branch pipe 41, the change in the extension length of the adjusting screw 311 will push the spray branch pipe 41 to rotate around the hinge 410, thereby achieving precise adjustment and locking of the pitch angle and tilt angle of the spray branch pipe 41. The spraying mechanism 4 also includes a blower 43, which is fixedly connected to the tail of the spray branch pipe 41 to provide wind power to blow water mist to a greater distance. The spraying mechanism 4 also includes multiple atomizing spray heads 42, which are installed at the front end of the spray branch pipe 41. The atomizing spray heads 42 are used to atomize the water flow into fine water droplets.

[0029] This utility model may also include the following preferred technical solutions, please refer to Figure 1 , Figure 2 and Figure 4 The spraying mechanism 4 also includes a water storage tank 45, which is placed in the slot of the support base 314. The top of the water storage tank 45 is provided with a water inlet. The spraying mechanism 4 also includes a booster water pump 47, which is installed on the top of the water storage tank 45 to provide pressure for spraying. In order to facilitate observation of the water level and replacement of the water tank, a liquid level observation window 49 is provided on the front side of the water storage tank 45. The device also includes a movable door 2, which is hinged to the support base 314. The water storage tank 45 can be easily taken out or put in through the movable door 2. Please refer to Figure 4 and Figure 5The spraying mechanism 4 also includes a water supply pipe 48, which is connected to the booster pump 47 and is used to deliver pressurized water from the booster pump 47 to the atomizing spray head 42. The spraying mechanism 4 also includes a flow control valve 46, which is installed on the water supply pipe 48. Specifically, the flow control valve 46 is located between the water storage tank 45 and the booster pump 47 and is used to adjust the water supply volume. In order to achieve a reliable connection between the water supply pipe 48 and the atomizing spray head 42, the spraying mechanism 4 also includes a pipe connection port 44, which is fixedly connected to the inner wall of the spraying branch pipe 41. The water receiving pipe of the atomizing spray head 42 is fixed through the pipe connection port 44, so that the atomizing spray head 42 is connected to the water supply pipe 48 through the pipe connection port 44. Please refer to Figure 1 and Figure 2 To facilitate the movement and fixation of the device, the four corners of the bottom of the support base 314 are fixedly equipped with moving wheel sets 313, each of which is equipped with a braking mechanism. The edge of the support base 314 is provided with a handrail 315 to facilitate the operator to push the device.

[0030] Working principle: When the device needs to be moved to the construction area, the operator can hold the handle 315. Since the four corners of the bottom of the support base 314 are fixedly installed with moving wheels 313, the entire device can be easily pushed. After reaching the designated dust suppression operation point, the operator can step on the brake mechanism of the moving wheels 313, which are equipped with a braking mechanism, to firmly lock the support base 314 on the road surface, preventing the device from accidentally sliding or shifting during operation and ensuring the stability of the construction. Before starting the spraying operation, the spraying posture of the spraying mechanism 4 needs to be precisely adjusted. First, the height is adjusted. The operator rotates the adjustment handle 37. The adjustment handle 37 is connected to the locking pin 36 through gear transmission. Rotating the adjustment handle 37 can drive the locking pin 36 to disengage from a locking hole 35 on the telescopic support rod 32, releasing the axial lock on the telescopic support rod 32. At this time, the operator can pull the telescopic support rod 32 up and down. Since the telescopic support rod 32 slides into the interior of the fixed sleeve 31, and the outer wall of the telescopic support rod 32 is provided with a guide protrusion 33, the fixed sleeve 31... The inner wall of 1 is provided with an axial guide groove 34 that is adapted to it. The cooperation between the guide protrusion 33 and the axial guide groove 34 ensures that the telescopic support rod 32 can only move smoothly up and down along the axial direction of the fixed sleeve 31, avoiding rotational deviation during the adjustment process. When the telescopic support rod 32 is adjusted to the target height, the operator rotates the adjustment handle 37 in the opposite direction, so that the locking pin 36 is re-inserted into the nearest locking hole 35 under the action of the transmission mechanism, thus completing the height fixation of the telescopic support rod 32. Then, the horizontal adjustment is performed. The operator holds the rotation handle 310 on the outer wall of the rotating support 39 and applies a horizontal rotational force. Since the rotating support 39 is rotatably connected to the top of the telescopic support rod 32 through the bearing 38, the rotating support 39 can rotate easily and smoothly around the central axis of the telescopic support rod 32 with the assistance of the bearing 38. The rotation of the rotating support 39 will drive the entire spraying mechanism 4 fixed on it, including the spray branch pipe 41 and the blower 43, to perform synchronous horizontal turning, thereby achieving horizontal sweeping coverage of the dust suppression area. When adjusting the pitch angle, the operator rotates the positioning nut 312. The positioning nut 312 is threaded onto the end of the adjusting screw 311 that passes through the mounting hole of the rotating support 39. Rotating the positioning nut 312 causes it to move axially along the adjusting screw 311, thereby changing the actual extension length of the adjusting screw 311 relative to the rotating support 39. Since one end of the adjusting screw 311 is hinged to the inner wall of the spray branch pipe 41, and the spray branch pipe 41 is hinged to the outer support 411 of the rotating support 39 via the hinge 410, the change in the extension length of the adjusting screw 311 will push or pull. The spray branch pipe 41 is moved so that it rotates around the axis of the hinge 410, thereby adjusting the elevation or depression angle of the spray branch pipe 41 and accurately locking the attitude of the spray head. After all attitudes are adjusted, the booster pump 47 is started. The booster pump 47 is installed on top of the water storage tank 45, which is placed in the slot of the support base 314. The booster pump 47 draws water from the water storage tank 45 and pressurizes and delivers it through the water supply pipe 48. The water flows through the flow control valve 46 set on the water supply pipe 48. The operator can control the water supply by adjusting the opening of the flow control valve 46. During operation, the operator can monitor the remaining water level in the water tank 45 in real time through the liquid level observation window 49 on the front side of the water tank 45. When water needs to be added or the water tank 45 needs to be replaced, the water tank 45 can be easily removed through the movable door 2 hinged to the support base 314. The pressurized water continues to flow through the water supply pipe 48, enters the pipe connection port 44 fixedly connected to the inner wall of the spray branch pipe 41, and is finally distributed to multiple atomizing spray heads 42 installed at the front end of the spray branch pipe 41. The water flow is atomized into fine water droplets at the atomizing spray head 42. At the same time, the blower 43, which is fixedly connected to the tail of the spray branch pipe 41, is started. The blower 43 generates strong wind and blows the atomized water droplets to the construction dust area at a distance. Through the synergistic effect of the spraying mechanism 4, which is adjustable in height, level and pitch in three dimensions, and the blower 43, this utility model solves the problems of inconvenient adjustment and limited coverage of dust suppression devices in the prior art, and realizes precise and efficient dust suppression of dust sources.
