Description

A dust suppression device for highway construction Technical Field

[0001] This utility model relates to the field of dust suppression technology, specifically to a dust suppression device for highway construction. Background Technology

[0002] Dust from highway construction not only pollutes the environment but may also affect the health of nearby residents. The main sources of dust from highway construction are earthwork excavation, material transportation, and road paving. Fog cannons are widely used dust suppression equipment in highway construction. They mainly use high-pressure atomization technology to convert water into micron-sized water mist particles, which adsorb dust in the air and cause it to settle, thereby effectively suppressing the spread of construction dust.

[0003] Existing fog cannons, as mentioned in the authorized publication number CN 219023751 U "A Mobile Fog Cannon", have a limitation in dust suppression range because the nozzles can only be directed in one direction and position. This results in dust suppression blind spots due to the solidification of the spray trajectory. Operators often need to frequently move the base of the device to compensate for the insufficient spray coverage, which not only consumes manpower but also affects the dust suppression effect. Summary of the Invention

[0004] This invention addresses the problem of limited spray range in fog cannons used for dust suppression during highway construction; it provides a dust suppression device for highway construction that expands the spray range of fog cannons and improves dust suppression effectiveness.

[0005] To solve the above problems, the technical solution of this utility model is:

[0006] A dust suppression device for highway construction includes a fog cannon, a housing, a support plate, and a drive plate. The support plate is located on the outer top surface of the housing and its lower end is rotatably connected to the top plate of the housing via a rotating shaft. The fog cannon is mounted on the support plate. The drive plate is vertically mounted inside the housing and is driven to rotate by a motor. A groove is recessed on the circumference of the drive plate. The upper longitudinal section of the groove is an isosceles trapezoid with a wide opening and a narrow inner bottom. Multiple sets of teeth are spaced apart on one side of the groove, and multiple sets of teeth are opposite to the adjacent sets of teeth on the other side. The lower end of the rotating shaft extends into the groove and is connected to a bevel gear. The bevel gear meshes with the teeth that move to the upper end of the drive plate. A transmission component is provided on the upper side of the housing. When the support plate rotates, the transmission component drives the fog cannon to swing up and down.

[0007] Furthermore, a drive shaft is fixedly mounted at the center of the drive plate, and the rear end of the drive shaft is rotatably connected to the rear side plate of the housing, while the front end is driven to rotate by a motor located on the front side plate of the housing.

[0008] Furthermore, the front and rear sides of the top of the bearing plate are respectively fixed with a vertical cylinder and a column. The front end of the peripheral wall of the fog cannon is provided with a rotating rod one that passes through and is rotatably connected to the rear side plate of the vertical cylinder. The rear end of the peripheral wall of the fog cannon is rotatably connected to the column via a rotating rod two.

[0009] Furthermore, the transmission component includes a second bevel gear and a drive rod. The free end of the first rotating rod is connected to the second bevel gear located inside the vertical cylinder. The drive rod is located inside the vertical cylinder. The upper part of the drive rod is fitted with a third bevel gear that meshes with the second bevel gear. The lower end of the drive rod movably passes through the lower side plate and the support plate of the vertical cylinder. The drive rod is rotatably connected to the lower side plate of the vertical cylinder. When the drive rod rotates with the support plate, it is driven to rotate by the drive component on the housing.

[0010] Furthermore, the driving component includes an annular groove two. The outer top surface of the housing on the lower side of the bearing plate is recessed with an annular groove two. Multiple sets of teeth three are spaced apart on one side of the annular groove two, and multiple sets of teeth four are provided on the other side, which are opposite to the adjacent two sets of teeth three. The lower end of the driving rod extends into the annular groove two, and the lower end of the driving rod is connected to a spur gear located in the annular groove two. When the spur gear moves along the annular direction of the annular groove two, the spur gear meshes with teeth three or teeth four.

[0011] Furthermore, the second annular groove, the bearing plate, and the rotating shaft are coaxially arranged; the second annular groove is an annular groove with its opening facing upwards.

[0012] The beneficial effects of this utility model through the above technical solution are as follows:

[0013] When the fog cannon sprays water mist to suppress dust, the motor drives the drive plate to rotate. The drive plate drives the support plate to swing forward or backward via the rotating shaft, which in turn drives the fog cannon to swing back and forth. Moreover, when the support plate drives the fog cannon to swing back and forth, the spray end of the fog cannon can be driven to swing upward or downward via the transmission component. Therefore, the spray range of the fog cannon can be increased, and the dust suppression effect is improved. In addition, no manual adjustment is required, saving time and effort.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0020] As shown in Figures 1-4, a dust suppression device for highway construction includes a mist cannon 1, a housing 2, a support plate 3, and a drive plate 4. The housing 2 is a rectangular box with its lower opening sealed by a bottom plate. The support plate 3 is a circular plate, located on the outer top surface of the housing 2, and its lower end is rotatably connected to the top plate of the housing 2 via a rotating shaft 5. The rotating shaft 5 is rotatably connected to the top plate of the housing via a bearing. The mist cannon 1 is mounted on the support plate 3, with its right end serving as the spraying end. The drive plate 4 is a circular plate, vertically positioned inside the housing 2, and driven by a motor 6. When the drive plate 4 rotates, an annular groove 7 is recessed on its circumferential surface. The upper longitudinal section of the annular groove 7 is an isosceles trapezoidal shape with a wide opening and a narrow inner bottom. Multiple sets of teeth 8 are spaced apart on one side of the annular groove 7, and multiple sets of teeth 9 are provided on the other side, which are opposite to the adjacent sets of teeth 8. The lower end of the rotating shaft 5 extends into the annular groove 7 and is connected to a bevel gear 10. The bevel gear 10 meshes with the teeth 8 or teeth 9 that move to the upper end of the drive plate 4. A transmission component is provided on the upper side of the housing 2. When the bearing plate 3 rotates, the transmission component is used to drive the fog cannon 1 to swing up and down.

[0021] A drive shaft 11 is fixedly mounted in the center of the drive plate 4. The rear end of the drive shaft 11 is rotatably connected to the rear side plate of the housing 2, and the front end is driven to rotate by a motor 6 located on the front side plate of the housing 2.

[0022] The top front and rear parts of the bearing plate 3 are respectively fixed with a vertical tube 12 and a column 13. The vertical tube 12 is a rectangular tube with its lower opening blocked by a lower side plate. The column 13 is a rectangular column. The front end of the peripheral wall of the fog cannon tube 1 is provided with a rotating rod 14 that passes through and is rotatably connected to the rear side plate of the vertical tube 12. The rear end of the peripheral wall of the fog cannon tube 1 is rotatably connected to the column 13 via a rotating rod 2 15.

[0023] The transmission component includes a second bevel gear 16 and a drive rod 17. The free end of the rotating rod 14 is connected to the second bevel gear 16 located inside the vertical cylinder 12. The drive rod 17 is located inside the vertical cylinder 12. The upper part of the drive rod 17 is fitted with a third bevel gear 18 that meshes with the second bevel gear 16. The upper end of the drive rod 17 is rotatably connected to the top plate of the vertical cylinder 12. The lower end of the drive rod 17 movably passes through the lower side plate of the vertical cylinder 12 and the support plate 3. The drive rod 17 is rotatably connected to the lower side plate of the vertical cylinder 12 via a second bearing. When the drive rod 17 rotates with the support plate 3, it is driven to rotate by the drive component on the housing 2.

[0024] The driving component includes an annular groove 19. The outer top surface of the housing 2 on the lower side of the bearing plate 3 is recessed with an annular groove 19. Multiple sets of teeth 20 are spaced apart on one side of the annular groove 19, and multiple sets of teeth 21 are provided on the other side, which are opposite to the adjacent sets of teeth 20. The lower end of the driving rod 17 extends into the annular groove 19. The lower end of the driving rod 17 is connected to a spur gear 22 located in the annular groove 19. When the spur gear moves along the annular direction of the annular groove 19, the spur gear 22 meshes with the teeth 20 or the teeth 21.

[0025] The second annular groove 19, the bearing plate 3, and the rotating shaft 5 are coaxially arranged; the second annular groove 19 is an annular groove with the opening facing upward.

[0026] In use, the housing 2 of this utility model is mounted on a movable device, which moves the utility model to a designated area. The spray end of the mist cannon 1 faces the dust suppression area that needs to be sprayed with water mist. Initially, the spray end of the mist cannon 1 is horizontal. When the mist cannon 1 sprays water mist, the motor 6 drives the drive plate 4 to rotate clockwise (the clockwise rotation of the drive plate 4 is the left view in Figure 3). When any set of teeth 8 moves to the upper end of the drive plate 4, at this time, teeth 8 mesh with bevel gear 10, and bevel gear 10 drives the rotating shaft 5 to rotate counterclockwise (the counterclockwise rotation of the rotating shaft 5 is the top view in Figure 3). The bearing plate 3 rotates counterclockwise with the rotating shaft 5. The vertical cylinder 12 and column 13 drive the fog cannon 1 to rotate counterclockwise. As the drive plate 4 continues to rotate, the tooth 8 at the upper end of the drive plate 4 disengages from the bevel gear 10 and moves to a set of teeth 9 at the upper end of the drive plate 4 to mesh with the bevel gear 10. The teeth 9 drive the bevel gear 10 to drive the rotating shaft 5 to rotate clockwise (the clockwise rotation of the rotating shaft 5 is the top view in Figure 3). The bearing plate 3 drives the fog cannon 1 to rotate clockwise along with the rotating shaft 5. Therefore, during the continuous rotation of the drive plate 4 driven by the motor 6, the teeth 8 and teeth 9 on the drive plate 4 alternately drive the bearing plate 3 to rotate back and forth. When the bearing plate 3 rotates counterclockwise or clockwise, it can drive the fog cannon 1 to swing back and forth.

[0027] Furthermore, when the support plate 3 rotates counterclockwise, the drive rod 17 moves with the support plate 3. The drive rod 17 drives the spur gear 22 to move along the annular direction of the annular groove 19. During the movement of the spur gear 22, when the spur gear 22 meshes with any set of teeth 20, the drive rod 17 rotates clockwise (the clockwise rotation of the drive rod 17 is the top view in Figure 2). The bevel gear 18 rotates with the drive rod 17, and the bevel gear 18 meshes with the bevel gear 16, driving the rotating rod 14 to rotate counterclockwise (the counterclockwise rotation of the rotating rod 14 is the left view in Figure 2). The fog cannon 1 rotates counterclockwise with the rotating rod 14, and the spray end gradually moves upward. 22 continues to move along the annular groove 29. After the spur gear 22 disengages from the tooth 3 20, it begins to mesh with the tooth 4 21. The drive rod 17 rotates counterclockwise, which in turn drives the rotating rod 14 to rotate clockwise. As the rotating rod 14 rotates clockwise, the fog cannon 1 moves with its spray end gradually pointing downwards. Similarly, when the support plate 3 rotates clockwise, the spur gear 22 on the drive rod 17 can also alternately mesh with the tooth 3 20 or the tooth 4 21, which can also drive the fog cannon 1 to swing up and down. Therefore, when the motor 6 of this utility model drives the fog cannon 1 to swing back and forth, it can drive the fog cannon 1 to swing up and down through the transmission component, thereby increasing the spray range of the spray end of the fog cannon 1.

However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
