[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

When large-scale mechanical construction is carried out in a local area of ​​the construction site, a large amount of dust is easily generated. At this time, the multiple electric sliders 11 cooperate with the connecting components to drive the dust reduction boxes 12 to slide and gather in the large-scale mechanical construction area for spraying and dust reduction. After the large-scale mechanical construction is completed, the multiple dust reduction boxes 12 are reset and continue to spray water for dust reduction, which plays the effect of adjusting the dust reduction range according to different construction environments, replaces the traditional dust reduction equipment that is too large in size, and is suitable for various complex construction environments where walls can be built, thereby improving the dust reduction effect on road and bridge construction.

[0031] like Figures 1 to 4 , Figure 7As shown, the connecting assembly includes a No. 1 connecting rod 2, a No. 2 connecting rod 21, a sliding plate 22 and a No. 2 pipe 23; the No. 1 connecting rod 2 is fixedly connected to the outside of a dust reduction box 12; the No. 2 connecting rod 21 is slidably connected to the inner wall of the No. 1 connecting rod 2; a plurality of sliding plates 22 are slidably connected to the inner wall of the dust reduction track 1, and a plurality of sliding plates 22 are all fixedly connected to the dust reduction box 12, and one end of the No. 2 connecting rod 21 away from the No. 1 connecting rod 2 is fixedly connected to the outer wall of the dust reduction box 12 on the sliding plate 22; the No. 2 pipe 2 3 is fixed to the outer wall of the dust suppression box 12 on the sliding plate 22, and the second pipe 23 is slidably connected to the inner wall of the first pipe 13 on the electric slider 11; when dust is suppressed around the road and bridge construction, the two electric sliders 11 slide on the two ends of the dust suppression track 1 respectively, and the multiple sliding plates 22 are installed between the two electric sliders 11. The two electric sliders 11 and the multiple sliding plates 22 are all fixed with dust suppression boxes 12. The multiple dust suppression boxes 12 are connected by the first connecting rod 2 and the second connecting rod 21. The two dust suppression boxes 12 are connected by a The No. 1 pipe 13 and the No. 2 pipe 23 are connected to the water source. After the water pump 16 pumps water into the water inlet pipe 14, the water is sent from one end of the No. 1 pipe 13 to a dust suppression box 12, and part of the water is sent from the other end of the No. 1 pipe 13 to another dust suppression box 12 connected to the No. 2 pipe 23. Finally, the dust is sprayed from the four-hole groove 15, which plays a role in connecting multiple dust suppression boxes 12. When dust is gathered in a local area, the two electric sliders 11 slide close to each other, driving the No. 2 connecting rod 21 on a dust suppression box 12. The dust reduction box 12 is retracted into the interior of the No. 1 connecting rod 2 of another dust reduction box 12. After the No. 2 connecting rod 21 slides from the front end inside the No. 1 connecting rod 2 to the end inside the No. 1 connecting rod 2, the No. 2 pipe 23 is synchronously retracted into the interior of the No. 1 pipe 13. Then the dust reduction box 12 on the electric slider 11 can push the dust reduction box 12 on the sliding plate 22 to slide synchronously, so that multiple dust reduction boxes 12 are gathered in the large machinery construction area for dust reduction. After the dust reduction is completed, the multiple dust reduction boxes 12 can be reset by sliding in the opposite direction, thereby adjusting the dust reduction range.

[0032] like Figures 1 to 4 As shown, a plurality of the dust suppression boxes 12 are provided with a No. 2 double hole 31, and the No. 2 double hole 31 is located below the four-hole slot 15; a plurality of the dust suppression boxes 12 are provided with a No. 1 double hole 3, and the No. 1 double hole 3 is located below the No. 2 double hole 31, the No. 1 double hole 3 and the No. 2 double hole 31 are vertically arranged, and a plurality of No. 2 atomizing nozzles are fixedly connected to the No. 1 double hole 3 and the No. 2 double hole 31; when dust is suppressed during road and bridge construction, due to the small construction volume in some areas, large-scale water spraying for dust suppression is likely to cause waste of resources, and the No. 1 double hole 3 and the No. 2 double hole 31 provided on the dust suppression box 12 are used as spray holes, and according to the planning of the construction site, the No. 1 double hole 3 or the No. 2 double hole 31 is selected to cooperate with the No. 2 atomizing nozzle for spraying dust suppression, and the remaining spray holes are blocked, so as to achieve the effect of slight dust suppression in areas with small local construction volume.

[0033] like Figures 1 to 5 As shown, the inner walls of the plurality of dust suppression boxes 12 are slidably connected with a switching plate 4; the switching plate 4 is provided with four holes, and the four holes correspond to the four-hole grooves 15; the switching plate 4 is provided with a water inlet hole 41 on the side close to the No. 1 pipe 13, and the water inlet hole 41 corresponds to the No. 1 pipe 13; when switching between the No. 1 double hole 3, the No. 2 double hole 31 and the four-hole groove 15, the water pump 16 is provided with three gears. When the output power of the water pump 16 is adjusted to the first gear, the water pressure is relatively small, and the water entering the dust suppression box 12 can enter the interior of the switching plate 4 through the water inlet hole 41 for flushing, flushing the switching plate 4 up to open the No. 1 double hole 3 to spray water by atomization. At this time, the No. 2 double hole 31 and the four-hole groove 15 are blocked by the switching plate 4. ; When the output power of the water pump 16 is adjusted to the second gear, the water pressure is greater than the first gear water pressure, and the water entering the dust reduction box 12 can flush the switch plate 4 up to the top until the second double hole 31 is opened and the water is atomized and sprayed. At this time, the No. 1 double hole 3 and the four-hole slot 15 are blocked by the switch plate 4; when the output power of the water pump 16 is adjusted to the third gear, the water pressure is greater than the second gear water pressure, and the water entering the dust reduction box 12 can flush the switch plate 4 up to the top until the four-hole slot 15 is opened and the water is atomized and sprayed. At this time, the No. 1 double hole 3 and the No. 2 double hole 31 are blocked by the switch plate 4. When the water pump 16 lowers the gear, the switch plate 4 will slide down due to its own gravity until it reaches the lowest gear, thereby switching between the No. 1 double hole 3, the No. 2 double hole 31 and the four-hole slot 15 for dust reduction.

[0034] like Figures 1 to 4 As shown, multiple limit blocks 5 are slidably connected to the inner walls of the multiple dust reduction boxes 12, and multiple limit blocks 5 are located at the switching plate 4; multiple limit blocks 5 are fixedly connected to the inner walls of the dust reduction box 12; when switching between the No. 1 double hole 3, the No. 2 double hole 31 and the four-hole groove 15, multiple limit blocks 5 are used in conjunction with the No. 1 elastic member to be set at the sliding position of the switching plate 4. When the water pump 16 increases the water pressure to flush the switching plate 4 and slide up, the switching plate 4 will squeeze the limit blocks 5 into the inner wall of the dust reduction box 12, thereby achieving the effect of switching between the No. 1 double hole 3, the No. 2 double hole 31 and the four-hole groove 15. The multiple limit blocks 5 are mainly used to increase the resistance when switching between the No. 1 double hole 3, the No. 2 double hole 31 and the four-hole groove 15, and play a role in assisting the limiting of the switching plate 4.

[0035] A plurality of the dust reduction boxes 12 are fixedly connected to the inside with a shunt pipe 6, and the shunt pipe 6 passes through the dust reduction box 12 and the sliding plate 22; a solenoid valve 61 is fixedly connected to the inner wall of the shunt pipe 6 near the No. 1 pipe 13; when the dust reduction track 1 is built on the wall of the road and bridge construction for a long time, the internal slide groove of the dust reduction track 1 is prone to accumulate impurities and dust, affecting the sliding effect of the electric slider 11 and the sliding plate 22. The dust reduction box 12 is driven to slide by the plurality of electric sliders 11 and the sliding plate 22, and the solenoid valve 61 in the dust reduction box 12 is opened. When water enters the dust reduction box 12, part of the water enters the inside of the shunt pipe 6, and the bottom end of the shunt pipe 6 flushes the internal slide groove of the dust reduction track 1, thereby reducing the influence of impurities on the sliding of the electric slider 11 and the sliding plate 22.

[0036] A shovel plate 7 is fixedly connected to the bottom end of the diverter pipe 6, and the shovel plate 7 is located at the bottom end of the sliding plate 22; spray holes 71 are opened on both sides of the shovel plate 7, and the spray holes 71 are connected to the diverter pipe 6; when a large amount of impurities are accumulated in the internal slide groove of the dust reduction track 1, the shovel plate 7 at the bottom end of the diverter pipe 6 is driven to scrape the internal slide groove of the dust reduction track 1 during the sliding process of the electric slider 11 and the sliding plate 22 to scrape away the impurities, and when scraping the impurities, the spray holes 71 connected to the diverter pipe 6 are sprayed to improve the cleaning effect of the impurities in the internal slide groove of the dust reduction track 1.

[0037] like Figure 1 , Figure 2 and Figure 6 As shown, the inner wall of the dust reduction track 1 is slidably connected with a plurality of squeezing rods 8; a plurality of sensors are installed inside the dust reduction track 1, and the sensors are electrically connected to the solenoid valve 61; a No. 2 elastic member is fixedly connected between the plurality of squeezing rods 8 and the sensors; when the plurality of electric sliders 11 and the sliding plates 22 slide, the plurality of squeezing rods 8 are squeezed respectively during the sliding process of the plurality of electric sliders 11 and the sliding plates 22, and the squeezing rods 8 are squeezed and contracted synchronously with the No. 2 elastic member, and the squeezing rods 8 trigger the sensor, which is a pressure sensor. After being squeezed, the sensor will send a signal to the controller, and the controller will send a signal to the nearest solenoid valve 61 to open, and the solenoid valve 61 will open within the set time, so that water can enter the inside of the diversion pipe 6, and the solenoid valve 61 will close after the set time, thereby realizing the function of automatically controlling the opening and closing of the solenoid valve 61.

[0038] A plurality of downstream grooves 9 are provided at the bottom end of the dust reduction track 1; filter plates 91 are fixedly connected to the inner walls of the plurality of downstream grooves 9; when cleaning the impurities in the internal slide groove of the dust reduction track 1, the impurities are scraped by the shovel plate 7, and the shovel plate 7 slides along with the electric slider 11 and the sliding plate 22 until the scraped impurities and the sprayed water are sent into the plurality of downstream grooves 9, and the filter plate 91 will filter the impurities on its surface, and the water will flow down through the filter plate 91, which can be used for water recovery and treatment, thereby playing the role of collecting the impurities scraped by the scraper.

[0039] like Figures 1 to 4 , Figure 7 As shown, the dust reduction boxes 12 on the two sliding plates 22 can be connected by a No. 1 connecting rod 2 and a No. 2 connecting rod 21; the two dust reduction boxes 12 are connected by a No. 1 pipe 13 and a No. 2 pipe 23; when multiple sliding plates 22 are installed on the inner wall of the dust reduction track 1 for sliding use, a No. 1 connecting rod 2 and a No. 2 connecting rod 21 can be built between the dust reduction boxes 12 on the two sliding plates 22 as a connection, and a No. 1 connecting rod 2 and a No. 2 connecting rod 21 can also be built between a sliding plate 22 and a dust reduction box 12 on an electric slider 11 as a connection, which is mainly used to synchronously drive the aggregation and diffusion of multiple dust reduction boxes 12. The two dust reduction boxes 12 are connected by a No. 1 pipe 13 and a No. 2 pipe 23, which can mainly reduce the unstable water pressure, thereby improving the dust reduction effect on road and bridge construction.

[0040] Working process: When reducing dust around road and bridge construction, first build the dust reduction track 1 on the fence of the road and bridge construction, the input pipe of the water pump 16 is connected to the nearby water source, and the output pipe of the water pump 16 can be connected to the multiple water inlet pipes 14 through multiple external pipes. The water pump 16 starts to pump water and sends the water source to the multiple water inlet pipes 14 respectively, and then the multiple water inlet pipes 14 are sent to the multiple No. 1 pipes 13. Then the water is sent to the multiple dust reduction boxes 12 and sprayed out by the multiple No. 1 atomizing nozzles at the four-hole slot 15 to reduce dust around the road and bridge construction. When large-scale mechanical construction is carried out in a local area of ​​the construction site, a large amount of dust is easily generated. When the dust is removed from the construction area, the dust removal boxes 12 are moved to the construction site by the electric sliders 11 and the connecting components, respectively. The electric sliders 11 are used to drive the dust removal boxes 12 to slide and gather to the large machinery construction area for spraying and dust reduction. After the large machinery construction is completed, the dust removal boxes 12 are reset and continue to spray water for dust reduction, thereby adjusting the dust reduction range according to different construction environments, replacing the traditional dust reduction equipment that is too large in size, and being suitable for various complex construction environments where walls can be built, thereby improving the dust reduction effect on road and bridge construction. When dust is removed around the road and bridge construction, the two electric sliders 11 slide at the two ends of the dust reduction track 1, respectively, and the multiple sliding plates 22 are installed between the two electric sliders 11. Dust suppression boxes 12 are fixedly connected to each electric slider 11 and multiple sliding plates 22. Multiple dust suppression boxes 12 are connected by No. 1 connecting rod 2 and No. 2 connecting rod 21. The two dust suppression boxes 12 are connected to the water source through No. 1 pipe 13 and No. 2 pipe 23. After the water pump 16 pumps water into the water inlet pipe 14, the water is sent into one dust suppression box 12 from one end of the No. 1 pipe 13, and part of the water is sent into another dust suppression box 12 connected to the No. 2 pipe 23 from the other end of the No. 1 pipe 13. Finally, dust is sprayed from the four-hole groove 15, which plays a role in connecting multiple dust suppression boxes 12. When dust is gathered in a local area, , the two electric sliders 11 slide close to each other, driving the No. 2 connecting rod 21 on one dust reduction box 12 to retract into the No. 1 connecting rod 2 of the other dust reduction box 12. After the No. 2 connecting rod 21 slides from the front end of the No. 1 connecting rod 2 to the end of the No. 1 connecting rod 2, the No. 2 pipe 23 is synchronously retracted into the No. 1 pipe 13. Then, the dust reduction box 12 on the electric slider 11 can push the dust reduction box 12 on the sliding plate 22 to slide synchronously, so that multiple dust reduction boxes 12 gather in the large mechanical construction area for dust reduction. After the dust reduction is completed, the multiple dust reduction boxes 12 can be reset by sliding in the reverse direction, thereby adjusting the dust reduction range.

[0041] When dust is suppressed during road and bridge construction, large-scale water spraying for dust suppression may cause waste of resources due to the small amount of construction in some areas. The No. 1 double hole 3 and the No. 2 double hole 31 opened on the dust suppression box 12 are used as spray holes. According to the planning of the construction site, the No. 1 double hole 3 or the No. 2 double hole 31 is selected to cooperate with the No. 2 atomizing nozzle for spraying dust suppression, and the remaining spray holes are blocked, thereby achieving the effect of slight dust suppression in the area with small local construction volume; when switching between the No. 1 double hole 3, the No. 2 double hole 31 and the four-hole slot 15, the water pump 16 is set There are three gears. When the output power of the water pump 16 is adjusted to the first gear, the water pressure is relatively small, and the water entering the dust suppression box 12 can enter the interior of the switching plate 4 through the water inlet hole 41 to flush the switching plate 4, flushing the switching plate 4 to the top until the No. 1 double hole 3 is opened to spray water. At this time, the No. 2 double hole 31 and the four-hole slot 15 are blocked by the switching plate 4; when the output power of the water pump 16 is adjusted to the second gear, the water pressure is greater than the first gear water pressure, and the water entering the dust suppression box 12 can flush the switching plate 4 to the top until the No. 2 double hole 31 is opened to spray water. At this time, the No. 1 double hole 31 and the four-hole slot 15 are blocked by the switching plate 4. The hole 3 and the four-hole slot 15 are blocked by the switching plate 4; when the output power of the water pump 16 is adjusted to the third gear, it is greater than the second gear water pressure, and the water entering the dust suppression box 12 can flush the switching plate 4 up to open the four-hole slot 15 to spray water. At this time, the No. 1 double hole 3 and the No. 2 double hole 31 are blocked by the switching plate 4. When the water pump 16 lowers the gear, the switching plate 4 will slide down due to its own gravity until it reaches the lowest gear, which plays a role in switching between the No. 1 double hole 3, the No. 2 double hole 31 and the four-hole slot 15 for dust suppression; when the No. 1 double hole 3 When switching between the No. 1 double hole 31 and the four-hole slot 15, a plurality of limit blocks 5 are used in conjunction with the No. 1 elastic member to be set at the sliding position of the switching plate 4. When the water pump 16 increases the water pressure to flush the switching plate 4 and slides upward, the switching plate 4 will squeeze the limit blocks 5 into the inner wall of the dust suppression box 12, thereby achieving the effect of switching between the No. 1 double hole 3, the No. 2 double hole 31 and the four-hole slot 15. The plurality of limit blocks 5 are mainly used to increase the resistance when switching between the No. 1 double hole 3, the No. 2 double hole 31 and the four-hole slot 15, and play a role in assisting the limiting of the switching plate 4;

[0042] When the dust reduction track 1 is built on the fence of the road and bridge construction for a long time, the internal chute of the dust reduction track 1 is prone to accumulate impurities and dust, which affects the sliding effect of the electric slider 11 and the sliding plate 22. The dust reduction box 12 is driven to slide by using multiple electric sliders 11 and the sliding plate 22, and the solenoid valve 61 in the dust reduction box 12 is opened. When water enters the dust reduction box 12, part of the water enters the inside of the shunt pipe 6, and the internal chute of the dust reduction track 1 is flushed by the bottom end of the shunt pipe 6, thereby reducing the influence of impurities on the sliding of the electric slider 11 and the sliding plate 22; when a large amount of impurities accumulate in the internal chute of the dust reduction track 1, the shovel plate 7 at the bottom end of the shunt pipe 6 is driven to scrape the internal chute of the dust reduction track 1 during the sliding of the electric slider 11 and the sliding plate 22, and the impurities are scraped away, and when scraping the impurities, the spray hole 71 connected to the shunt pipe 6 is sprayed to improve the cleaning effect of the impurities in the internal chute of the dust reduction track 1;

[0043] When the multiple electric sliders 11 and the sliding plate 22 slide, the multiple squeezing rods 8 are squeezed respectively during the sliding process of the multiple electric sliders 11 and the sliding plate 22. After the squeezing rods 8 are squeezed, the second elastic member is squeezed and contracted synchronously, and the squeezing rods 8 trigger the sensor, which is a pressure sensor. After the sensor is squeezed, it will send a signal to the controller. The controller sends a signal to the nearest solenoid valve 61 to open. The solenoid valve 61 will open within a set time, so that water can enter the inside of the diversion pipe 6. The solenoid valve 61 will close after the set time, realizing the function of automatically controlling the opening and closing of the solenoid valve 61;

[0044] When cleaning the impurities in the chute inside the dust reduction track 1, the shovel plate 7 is used to scrape the impurities. The shovel plate 7 slides along the electric slider 11 and the sliding plate 22 until the scraped impurities and the sprayed water are sent to multiple downstream troughs 9. The filter plate 91 will filter the impurities on its surface, and the water will flow down through the filter plate 91, which can be used for water recovery and treatment, thereby playing the role of collecting impurities on the scraper.
