Description

Technical Field

[0001] The invention relates to the technical field of road maintenance, and in particular to a road bridge and tunnel construction device. Background Art

[0002] Road maintenance is the maintenance and upkeep of roads, roads and structures and facilities on them, maintaining road performance as much as possible, ensuring safe, comfortable and smooth driving, and saving transportation costs and time. In the hot summer, roads are prone to thermal expansion, and workers need to spray water on the road to cool it down or remove dust on the road surface. In existing road maintenance spraying devices, road maintenance agents are prone to precipitation in the water bucket, resulting in a low content of maintenance agents in the sprayed water, and the road maintenance effect is not obvious.

[0003] In order to solve the above problems, a Chinese patent with publication number CN217973968U discloses a road maintenance spraying device for road bridges and tunnels, including a vehicle floor, dampers are fixedly connected at both ends of the bottom of the fixed block, support rods are penetrated and slidably connected at the center of the bottom of the two dampers, a motor is fixedly connected at the middle position on the left side of the bottom of the vehicle floor, a rotating rod is fixedly connected at the output end of the motor, a high-pressure water pump is fixedly connected near the center position on the right side of the top of the vehicle floor, a water spray plate is penetrated and rotatably connected on the support shaft, and multiple uniformly distributed water spray ports are penetrated and fixedly connected on the right side of the water spray plate. When the motor is working, the rotating rod is driven to rotate, thereby driving the stirring paddle to rotate, and at the same time, the water in the bucket is stirred and mixed with the curing agent under the cooperation of the auxiliary stirring paddle, so as to prevent the curing agent from settling at the bottom of the bucket due to the long spraying time, so that the curing agent content in the sprayed water is low, and the road maintenance effect is not obvious.

[0004] The above-mentioned device has the following problems during actual use: the device can only spray water on the dust adhering to the surface of the road surface through the water spray plate to achieve the flushing and cleaning of the dust, but during the maintenance of the road surface, a large amount of dust will be diffused above the road surface. If the dust is not promptly treated, the environment of the road surface will be polluted by the dust, thereby reducing the environmental comfort of the construction environment, and the workers will also inhale more dust, causing harm to their health, that is, the practicability is low and the maintenance effect of the road surface is poor. Summary of the invention

[0005] The invention provides a road bridge and tunnel construction device to solve the problem that the existing spraying device cannot perform dust reduction treatment on the dust dispersed on the road surface.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a road bridge and tunnel construction device, a mobile base, a water storage tank, the water storage tank is fixedly connected to the mobile base, and also includes an installation box with a bottom opening and an adjustment mechanism arranged in the installation box; the installation box is fixedly connected to the water tank, and air ports are opened on both sides of the installation box; the maintenance mechanism includes a vertical pipe, a horizontal pipe, and an adjustment component symmetrically arranged on both sides of the vertical pipe along the length direction of the vertical pipe; the vertical pipe is fixedly connected to the installation box, and the vertical pipe is connected to the water tank; the horizontal pipe is connected to the free end of the vertical pipe; the adjustment component includes an adjustment pipe, an atomizing nozzle, a maintenance part , a side hole opened on the vertical tube, a top hole opened on the transverse tube, an adjusting block for sealing the top hole, and a driving part for driving the adjusting block to reciprocate along the length direction of the transverse tube; the two ends of the adjusting tube are respectively connected with the side hole and the top hole; the atomizing nozzle is connected with the free end of the transverse tube, and the free end of the atomizing nozzle faces the air port; the maintenance part includes a plurality of maintenance units equidistantly arranged along the length direction of the transverse tube; the maintenance unit includes a maintenance pipe and a bottom hole opened on the transverse tube; the maintenance pipe is connected with the outer wall of the bottom of the transverse tube, and the maintenance pipe is connected with the bottom hole; the adjusting block is slidably connected with the inner wall of the transverse tube.

[0007] The principles and advantages of this solution are:

[0008] 1. When the road surface needs to be maintained, the maintenance liquid is introduced into the vertical pipe through the water storage tank, and the maintenance liquid is then discharged through the horizontal pipe and the maintenance pipe and acts on the road surface to achieve the maintenance of the road surface. While the maintenance pipe sprays the maintenance liquid, the drive unit drives the adjustment block to reciprocate along the length direction of the horizontal pipe. When the two adjustment blocks are close to each other, the adjustment blocks will gradually block the bottom holes, thereby reducing the number of bottom holes through which the maintenance liquid can flow, that is, the pressure of the maintenance liquid sprayed through the maintenance pipe will increase, with a stronger force and a longer action distance. After the force of the maintenance liquid is enhanced, it will act on the road surface to form a splashing liquid. The splashing liquid can expand the area of ​​contact with the road surface, thereby allowing the maintenance liquid to better wash the dust adhering to the road surface, reduce the amount of dust adhering to the road surface, improve the cleanliness of the road surface, enhance the maintenance effect on the road surface, and improve the maintenance efficiency.

[0009] 2. When the two adjustment blocks are close to each other, that is, when the adjustment blocks move away from the top hole, the adjustment blocks will gradually be misaligned with the top hole, so that the curing liquid in the vertical pipe can flow to the liquid outlet of the horizontal pipe through the adjustment pipe. When the curing liquid flows to the liquid outlet of the horizontal pipe, the curing liquid will be transformed into atomized liquid by the atomizing nozzle. When the atomized liquid is sprayed out, it can reduce the dust dispersed on the road surface, thereby reducing the amount of dust dispersion, improving the environmental comfort of the road surface, and reducing the pollution of dust to the environment and the harm to the staff.

[0010] To sum up, by moving the two adjusting blocks closer to or farther away from each other, the maintenance liquid flowing into the transverse pipe can be pressurized and converted into atomized liquid. On the one hand, it expands the spraying area of ​​road pavement maintenance and enhances the maintenance effect of the road pavement. On the other hand, it improves the comfort of the road pavement environment and improves the practicability of the device.

[0011] Furthermore, the adjustment component also includes a linkage part; the linkage part includes a fixed block, a worm, a plurality of worm wheels equidistantly arranged along the axial direction of the worm, and a power part for driving the worm to rotate forward and reverse; the fixed block is fixedly connected to the outer wall of the bottom of the transverse tube; the worm is rotatably connected to the fixed block; the maintenance tube is rotatably connected to the transverse tube, the worm wheel is fixedly connected to the maintenance tube, and the worm wheel is meshed with the worm.

[0012] During the spraying of curing liquid by the curing pipe, the meshing of the worm wheel and the worm enables the curing pipe to rotate. During the rotation of the curing pipe, the curing pipe has a certain centrifugal force, and the curing liquid can be discharged from the circumferential direction of the curing pipe under the action of the centrifugal force, thereby expanding the curing liquid's action range, allowing the curing liquid to contact the road surface more fully and comprehensively, enhancing the effect of the curing liquid, improving the utilization rate of the curing liquid, and ensuring the curing quality of the road surface by the curing liquid.

[0013] Furthermore, the adjustment component also includes a swinging part; the swinging part includes a swinging shaft, a connecting block, a swinging block, a plurality of swinging units equidistantly arranged along the length direction of the swinging block, and a motion unit for driving the swinging shaft to rotate forward and reverse; the swinging shaft is rotatably connected to the fixed block; the two ends of the connecting block are respectively fixedly connected to the swinging shaft and the swinging block; the swinging unit includes a swinging tube and a limiting hole opened on the swinging block; the swinging tube is hinged to the maintenance tube, and the swinging tube is in contact with the limiting hole.

[0014] During the maintenance of the road surface by the maintenance pipe, the swing shaft is driven to rotate through the motion unit. During the rotation of the swing shaft, the swing shaft drives the swing block to move synchronously through the connecting block. During the movement of the swing block, the swing block can drive the swing pipe to swing back and forth. During the swing of the swing pipe, the water spraying path of the maintenance pipe can be changed, that is, the swing pipe can swing to spray water. During the swing of the swing pipe to spray water, the range of water spraying of the maintenance pipe will be further expanded, so that the maintenance liquid can be diffused over a large area, and then the maintenance liquid can have a more comprehensive and complete effect on the road surface, thereby further improving the utilization rate of the maintenance liquid, enhancing the maintenance effect, and ensuring the maintenance quality.

[0015] Furthermore, the adjustment component also includes an auxiliary part; the auxiliary part includes a guide block, a wedge block, a spring, a baffle plate, and a wedge surface opened on the adjustment block; the guide block is fixedly connected to the inner wall of the vertical tube; the wedge block is vertically slidably connected to the guide block; the two ends of the spring are respectively connected to the wedge block and the guide block; the baffle plate is fixedly connected to the wedge block, and the side hole is located on the movement trajectory of the baffle plate; the wedge block is located on the movement trajectory of the wedge surface.

[0016] As the two adjustment blocks gradually approach each other, more maintenance liquid can only move along the adjustment tube to the position close to the atomizing nozzle. During the movement of the adjustment block, when the wedge surface is in contact with the wedge block, the wedge surface continues to move, so that the wedge block can move vertically upward and the spring is compressed. During the vertical upward movement of the wedge block, the wedge block can drive the baffle to gradually move closer to the position where the side hole is located. During the movement of the baffle, the baffle can gradually reduce the diameter of the maintenance liquid flowing into the side hole, thereby accelerating the flow rate of the maintenance liquid flowing into the adjustment tube. Through the above movement, after the flow rate of the maintenance liquid increases, the atomized liquid sprayed from the atomizing nozzle has a stronger force and a wider range of action. That is, it ensures that the atomized liquid can efficiently, comprehensively and fully reduce the dust on the road surface, further enhances the dust reduction effect of the atomized liquid, and improves the efficiency of the atomized liquid.

[0017] Similarly, when the two adjustment blocks move away from each other, the baffle is reset under the action of the spring, and the baffle moves vertically downward, so that the effective distance of the atomized liquid sprayed from the atomizing nozzle gradually returns to the initial distance, so that the atomizing nozzle can spread the atomized liquid over a large area from near to far. That is, the effect of the atomizing nozzle is fully enhanced, ensuring that the atomized liquid can contact more dust when sprayed, so that the dust can be quickly reduced, and the dust reduction time is shortened.

[0018] Furthermore, the adjustment component also includes an extrusion part; the extrusion part includes a movable block, an extrusion block, and a power unit for driving the movable block to perform vertical reciprocating motion; the movable block is vertically slidably connected to the transverse tube; the extrusion block is fixedly connected to the movable block; the adjustment tube is a rubber tube, and the extrusion block is fixedly connected to the rubber tube.

[0019] During the vertical reciprocating motion of the movable block, the extrusion block moves synchronously. During the motion of the extrusion block, the extrusion block can continuously stretch and squeeze the rubber tube. During the stretching of the rubber tube, the amount of curing liquid that can flow in the rubber tube increases, so that a sufficient amount of curing liquid is converted into atomized liquid to reduce dust on the road surface, ensuring the dust reduction effect of the atomized liquid on the dispersed dust on the road surface.

[0020] During the period when the rubber tube is squeezed, the diameter of the tube through which the curing liquid flows in the rubber tube becomes smaller, thereby increasing the pressure in the rubber tube, causing the flow rate of the curing liquid flowing in the rubber tube to increase, further increasing the force of the atomized liquid when it is sprayed out, and increasing the effective distance of the atomized liquid, thereby ensuring that the atomized liquid can perform more efficient dust reduction treatment on the dust, thereby accelerating the progress of dust reduction treatment.

[0021] Furthermore, the adjustment component also includes a boosting part; the boosting part includes an elastic wind hood, a connecting plate, a bidirectional screw, a first guide rod, a boosting unit symmetrically arranged at both ends of the bidirectional screw, and a driving unit for driving the bidirectional screw to rotate forward and reverse; the elastic wind hood is connected to the air outlet of the transverse tube; the connecting plate is fixedly connected to the outer wall of the bottom of the transverse block; the bidirectional screw is rotatably connected to the connecting plate; the first guide rod is fixedly connected to the connecting plate; the boosting unit includes a nut seat and a boosting block; the nut seat is threadedly connected to the bidirectional screw, and the nut seat is slidably connected to the first guide rod; the boosting block is fixedly connected to the nut seat, and the elastic wind hood is located on the movement trajectory of the boosting block.

[0022] The elastic wind hood is set to expand the diameter of the atomized liquid when it is discharged, so that the atomized liquid can diffuse faster and wider after being pressurized by the baffle and rubber tube, thereby ensuring the dust reduction effect of the atomized liquid on dust and further shortening the dust reduction time of the atomized liquid on dust.

[0023] While the atomized liquid is flowing in the elastic wind hood, the two boosting blocks can be constantly moved closer or farther away through the rotation of the bidirectional screw. While the two boosting blocks are approaching each other, the two boosting blocks can squeeze the elastic wind hood, thereby causing the elastic wind hood to deform. After the elastic wind hood is deformed, the caliber of the elastic wind hood when discharging the atomized liquid can be reduced, thereby increasing the pressure inside the elastic wind hood, that is, after the atomized liquid is pressurized by the elastic wind hood, the force of the atomized liquid when it is discharged can be enhanced, thereby making the atomized liquid act at a greater distance, further expanding the range of action of the atomized liquid, and then enhancing the dust reduction effect of the atomized liquid on dust, ensuring that the dust on the road surface is reduced more comprehensively and fully.

[0024] Similarly, when the two booster blocks move away from each other, the elastic wind shield returns to its initial shape, and the distance of the atomized liquid gradually returns to the initial distance. That is, by continuously adjusting the distance that the atomized liquid can act, the atomized liquid can perform comprehensive dust reduction treatment on both nearby and distant dust, further reducing dust pollution to the environment and harm to workers.

[0025] Furthermore, the adjustment component also includes a blowing part; the blowing part includes a blowing shaft, fan blades, and an auxiliary unit for driving the blowing shaft to rotate; the blowing shaft is rotatably connected to the fixed block; the fan blades are fixed to the blowing shaft, and the air outlet of the elastic wind cover faces the fan blades.

[0026] The blower shaft is driven to rotate by the auxiliary unit, and the fan blades rotate synchronously during the rotation of the blower shaft. During the rotation of the fan blades, the effective distance of the atomized liquid and the effective range of the atomized liquid can be further increased, so that the atomized liquid can contact more dust, thereby making the dust reduction effect of the atomized liquid on the dust more significant, that is, shortening the dust reduction time and improving the dust reduction efficiency.

[0027] Moreover, during the rotation of the fan blades, the dust on the road surface can be dispersed, so that the dust does not accumulate, the dust content in the air is reduced, and the air quality is improved. At the same time, it is beneficial to the circulation of air on the road surface, that is, the flow speed of the atomized liquid and dust is increased, and the dust reduction progress is accelerated.

[0028] Furthermore, the driving part includes a one-way screw, a second guide rod, a first gear, a first rack, and a driving member for driving the first rack to perform vertical reciprocating motion; the one-way screw is rotatably connected to the inner wall of the transverse tube; the second guide rod is fixedly connected to the inner wall of the transverse tube; the adjustment block is threadedly connected to the one-way screw, and the adjustment block is slidably connected to the second guide rod; the first gear is fixedly connected to the one-way screw; the first rack is vertically slidably connected to the transverse tube, and the first rack is meshed with the first gear.

[0029] During the vertical reciprocating motion of the first rack, the first rack meshes with the first gear, so that the first gear can rotate forward or reverse. During the rotation of the first gear, the one-way screw rotates synchronously. During the rotation of the one-way screw, the adjustment block can reciprocate along the length direction of the second guide rod. Therefore, the two adjustment blocks can move closer to or farther away from each other.

[0030] Furthermore, the power unit is a second gear; the second gear is fixedly connected to the worm, and the second gear is meshed with the first rack.

[0031] Furthermore, the motion unit includes an incomplete bevel gear, a first bevel gear, and a second bevel gear; the incomplete bevel gear is fixedly connected to the blower shaft; the first bevel gear and the second bevel gear are both fixedly connected to the swing shaft; the incomplete bevel gear is located between the first bevel gear and the second bevel gear, and the first bevel gear and the second bevel gear can both mesh with the incomplete bevel gear.

[0032] During the rotation of the blower shaft, the incomplete bevel gear rotates synchronously. During the rotation of the incomplete bevel gear, when the incomplete bevel gear is meshed with the first bevel gear, the incomplete bevel gear is not meshed with the second bevel gear, and the swing shaft rotates forward; when the incomplete bevel gear is meshed with the second bevel gear, the incomplete bevel gear is not meshed with the first bevel gear, and the swing shaft rotates reversely. Therefore, the swing shaft can rotate forward and reverse. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] Specific implementation process:

[0058] When the road surface needs to be maintained, the water storage tank 2 and the installation box 4 are moved by the mobile base 1. During the movement of the installation box 4, the curing liquid is introduced into the vertical pipe 5 by the water pump in the water storage tank 2, and the curing liquid is then discharged through the transverse pipe 6 and the curing pipe 11 and acts on the road surface to achieve the maintenance of the road surface. During the curing liquid spraying of the curing pipe 11, the cylinder 37 is started. The first rack 36 is driven to move by the output shaft of the cylinder 37. During the vertical reciprocating motion of the first rack 36, since the first rack 36 is meshed with the first gear 35, the first gear 35 can rotate forward or reverse.

Therefore, the two adjustment blocks 10 can approach or move away from each other.

[0059] When the two adjusting blocks 10 are close to each other, the adjusting blocks 10 will gradually block the bottom holes 47, thereby reducing the number of bottom holes 47 through which the curing liquid can flow, that is, the pressure of the curing liquid sprayed through the curing pipe 11 will increase, with a stronger force and a longer acting distance. After the force of the curing liquid is enhanced, it will act on the road surface to form a splashing liquid, which can expand the area of ​​contact with the road surface, thereby allowing the curing liquid to better wash the dust adhering to the road surface, reduce the amount of dust adhering to the road surface, improve the cleanliness of the road surface, enhance the maintenance effect on the road surface, and improve the maintenance efficiency.

[0060] When the two adjustment blocks 10 are close to each other, that is, the adjustment blocks 10 move away from the top hole, the adjustment blocks 10 will gradually be misaligned with the top hole, so that the curing liquid in the vertical pipe 5 can flow to the liquid outlet of the horizontal pipe 6 through the adjustment pipe 7. When the curing liquid flows to the liquid outlet of the horizontal pipe 6, the curing liquid will be transformed into atomized liquid by the atomizing nozzle 8. When the atomized liquid is sprayed, it can reduce the dust dispersed on the road surface, thereby reducing the amount of dust dispersion, improving the environmental comfort of the road surface, and reducing the pollution of dust to the environment and the harm to the staff.

[0061] To sum up, by moving the two adjustment blocks 10 closer to or farther away from each other, the maintenance liquid flowing into the transverse pipe 6 can be pressurized and converted into an atomized liquid. On the one hand, the spraying area of ​​the road pavement maintenance is expanded and the maintenance effect of the road pavement is enhanced. On the other hand, the comfort of the road pavement environment is improved, thereby improving the practicality of the device.

[0062] During the spraying of curing liquid by the curing pipe 11, the first rack 36 meshes with the second gear 38, so that the second gear 38 can rotate forward and reverse. During the rotation of the second gear 38, the worm 13 rotates synchronously. During the rotation of the worm 13, the curing pipe 11 can rotate through the meshing of the worm wheel 14 and the worm 13. During the rotation of the curing pipe 11, the curing pipe 11 has a certain centrifugal force. Under the action of the centrifugal force, the curing liquid can be discharged from the circumferential direction of the curing pipe 11, thereby expanding the scope of action of the curing liquid, so that the curing liquid can contact the road surface more fully and comprehensively, enhance the effect of the curing liquid, improve the utilization rate of the curing liquid, and ensure the curing quality of the road surface by the curing liquid.

[0063] Meanwhile, while the maintenance pipe 11 is maintaining the road surface, the one-way screw 33 drives the third rack to make vertical reciprocating motion through the third gear 42. The third rack reciprocates vertically, and since the third rack is meshed with the fourth gear 46, the fourth gear 46 rotates. During the rotation of the fourth gear 46, the blower shaft 31 rotates synchronously. During the rotation of the blower shaft 31, the incomplete bevel gear 39 rotates synchronously. During the rotation of the incomplete bevel gear 39, when the incomplete bevel gear 39 is meshed with the first bevel gear 40, the incomplete bevel gear 39 is not meshed with the second bevel gear 41, and the swing shaft 15 rotates forward; when the incomplete bevel gear 39 is meshed with the second bevel gear 41, the incomplete bevel gear 39 is not meshed with the first bevel gear 40, and the swing shaft 15 rotates reversely. Therefore, the swing shaft 15 can rotate forward and reverse.

[0064] During the rotation of the swing shaft 15, the swing shaft 15 drives the swing block 17 to move synchronously through the connecting block 16. During the rotation of the swing shaft 15, the swing shaft 15 drives the swing block 17 to move synchronously through the connecting block 16. During the movement of the swing block 17, the swing block 17 can drive the swing tube 18 to swing back and forth. During the swinging of the swing tube 18, the water spraying path of the maintenance pipe 11 can be changed, that is, the swing tube 18 can swing to spray water. During the swinging of the swing tube 18 to spray water, the water spraying range of the maintenance pipe 11 will be further expanded, so that the maintenance liquid can be diffused over a large area, and then the maintenance liquid can have a more comprehensive and complete maintenance effect on the road surface, thereby further improving the utilization rate of the maintenance liquid, enhancing the maintenance effect, and ensuring the maintenance quality.

[0065] In summary, by increasing the pressure of the curing liquid flowing in the curing pipe 11 through the adjusting block 10, the rotation of the curing pipe 11 and the swinging of the swinging pipe 18 can comprehensively expand the curing area of ​​the curing liquid on the road surface, so that the curing liquid can fully and thoroughly wash the dust adhering to the road surface, thereby enhancing the curing effect of the curing liquid, comprehensively improving the utilization rate of the curing liquid, and shortening the maintenance time of the road surface.

[0066] As the two adjustment blocks 10 gradually approach each other, more maintenance liquid can only move along the adjustment tube 7 to the position close to the atomizing nozzle 8. During the movement of the adjustment block 10, when the wedge surface 22 is in contact with the wedge block 20, the wedge surface 22 continues to move, thereby enabling the wedge block 20 to move vertically upward, and the spring is compressed. During the vertical upward movement of the wedge block 20, the wedge block 20 can drive the baffle 21 to gradually move toward the position close to the side hole 9. During the movement of the baffle 21, the baffle 21 can gradually reduce the caliber of the maintenance liquid flowing into the side hole 9, thereby accelerating the flow rate of the maintenance liquid flowing into the adjustment tube 7. Through the above movement, after the flow rate of the maintenance liquid increases, the atomized liquid sprayed from the atomizing nozzle 8 has a stronger force and a wider range of action. That is, it is ensured that the atomized liquid can perform efficient, comprehensive and sufficient dust reduction treatment on the road surface, further enhancing the dust reduction effect of the atomized liquid and improving the efficiency of the atomized liquid.

[0067] Similarly, when the two adjustment blocks 10 move away from each other, the baffle 21 is reset under the action of the spring, and the baffle 21 moves vertically downward, so that the effective distance of the atomized liquid sprayed from the atomizing nozzle 8 gradually returns to the initial distance, so that the atomizing nozzle 8 can diffuse the atomized liquid over a large area from near to far. That is, the effect of the atomizing nozzle 8 is comprehensively enhanced, ensuring that the atomized liquid can contact more dust when sprayed, so that the dust can be quickly dusted, and the dusting time is shortened.

[0068] During the vertical reciprocating motion of the second rack 43, the movable block 23 moves synchronously. During the vertical reciprocating motion of the movable block 23, the extrusion block 24 moves synchronously. During the motion of the extrusion block 24, the extrusion block 24 can continuously stretch and squeeze the rubber tube. During the stretching of the rubber tube, the amount of curing liquid that can flow in the rubber tube increases, so that a sufficient amount of curing liquid is converted into atomized liquid to reduce dust on the road surface, ensuring the dust reduction effect of the atomized liquid on the dispersed dust on the road surface.

[0069] During the period when the rubber tube is squeezed, the diameter of the tube through which the curing liquid flows in the rubber tube becomes smaller, thereby increasing the pressure in the rubber tube, causing the flow rate of the curing liquid flowing in the rubber tube to increase, further increasing the force of the atomized liquid when it is sprayed out, and increasing the effective distance of the atomized liquid, thereby ensuring that the atomized liquid can perform more efficient dust reduction treatment on the dust, thereby accelerating the progress of dust reduction treatment.

[0070] The elastic wind hood 25 is provided to expand the diameter of the atomized liquid when it is discharged, so that the atomized liquid can diffuse faster and wider after being pressurized by the baffle 21 and the rubber tube, thereby ensuring the dust reduction effect of the atomized liquid on dust and further shortening the dust reduction time of the atomized liquid on dust.

[0071] During the flow of the atomized liquid in the elastic wind hood 25, the worm 13 meshes with the fourth bevel gear 45 through the third bevel gear 44, thereby driving the bidirectional screw 27 to rotate forward and reverse. Through the rotation of the bidirectional screw 27, the two boosting blocks 30 can continuously approach or move away. During the period when the two boosting blocks 30 approach each other, the two boosting blocks 30 can squeeze the elastic wind hood 25, thereby causing the elastic wind hood 25 to deform. After the elastic wind hood 25 is deformed, the caliber of the elastic wind hood 25 when discharging the atomized liquid can be reduced, thereby increasing the pressure in the elastic wind hood 25, that is, after the atomized liquid is pressurized by the elastic wind hood 25, the force of the atomized liquid when it is discharged can be enhanced, thereby making the atomized liquid act farther, further expanding the range of action of the atomized liquid, and then enhancing the dust reduction effect of the atomized liquid on dust, ensuring that the dust on the road surface is more comprehensive and sufficient.

[0072] Similarly, when the two booster blocks 30 are moving away from each other, the elastic wind shield 25 returns to its initial shape, and the distance of the atomized liquid gradually returns to the initial distance. That is, by continuously adjusting the distance that the atomized liquid can act, the atomized liquid can perform comprehensive dust reduction treatment on both nearby dust and distant dust, further reducing the pollution of dust to the environment and the harm to the staff.

[0073] The blower shaft 31 rotates, and during the rotation of the blower shaft 31, the fan blades 32 rotate synchronously; during the rotation of the fan blades 32, the effective distance of the atomized liquid and the effective range of the atomized liquid can be further increased, so that the atomized liquid can contact more dust, thereby making the dust reduction effect of the atomized liquid on the dust more significant, that is, shortening the dust reduction time and improving the dust reduction efficiency.

[0074] Furthermore, during the rotation of the fan blades 32, the dust on the road surface can be dispersed, so that the dust does not accumulate, the dust content in the air is reduced, and the air quality is improved. At the same time, it is beneficial to the circulation of air on the road surface, that is, the flow speed of the atomized liquid and dust is increased, and the dust reduction progress is accelerated.
