Description
Technical Field
[0001] This utility model relates to the technical field of dust suppression spraying devices, specifically a dust suppression spraying device for construction sites. Background Technology
[0002] Construction sites generate a large amount of dust during operations. This dust pollutes the air, negatively impacting worker health and hindering construction. Therefore, dust suppression measures are necessary. Most existing dust suppression devices on construction sites use multiple atomizing nozzles installed through water pipes for spraying. While these can suppress dust drifting towards the perimeter walls, the effect is not ideal and cannot effectively reduce dust over large areas. Utility Model Content
[0003] To overcome the above-mentioned shortcomings, this utility model provides a dust suppression spraying device for construction sites.
[0004] The technical solution adopted by this utility model is as follows:
[0005] A dust suppression spraying device for construction sites includes a water truck. A water tank is located on the upper part of the rear side panel of the water truck. A vent pipe is fixedly connected to the upper part of the water tank, communicating with the interior of the water tank. A water inlet is located on the front top of the water tank, and a cap is threaded onto the top of the inlet. Two lifting mechanisms are fixedly installed in the middle of the top of the water tank. An upper frame is installed on top of each lifting mechanism. The upper frame is a frame structure, and the upper part of the upper frame is a flat plate. A servo motor is fixedly installed at the bottom of the flat plate. The output shaft of the servo motor passes through the flat plate and is rotatably connected to it. A turntable is fixedly connected to the top of the servo motor's output shaft. The turntable is rotatably connected to the upper part of the flat plate. Fixed plates are vertically fixed to the front and rear sides of the top of the turntable. The top of the two nozzles is rotatably connected to each other. One end of the nozzle has a narrowed diameter, which is smaller than the other end. The two nozzles are positioned opposite each other. A ring pipe is fixedly connected to the small diameter end of the nozzle. Several nozzles are fixedly connected to the outer wall of the ring pipe and are evenly distributed around the ring pipe. A water spray connector is fixedly connected to the bottom of the ring pipe. A blower is fixedly installed on the inner wall of the large diameter end of the nozzle. The bottom of the nozzle is fixedly connected to the upper part of the connecting rod, which is close to the small diameter end of the nozzle. Two cylinders are rotatably connected to the top of the turntable. The two cylinders are distributed front and back. The bottom of the cylinder barrels of the two cylinders are rotatably connected to the top of the two turntables respectively. The piston rod ends of the two cylinders are rotatably connected to the bottom of the connecting rod respectively. The connecting rod has an inverted U-shaped structure.
[0006] Two submersible pumps are installed on the inner bottom wall of the water tank. The output end of the submersible pumps is fixedly connected to a hose. The other end of the two hoses is fixedly connected to two water spray connectors respectively. The hoses pass through the top of the water tank and are fixedly connected to the top of the water tank.
[0007] The lifting mechanism includes a lower frame, an upper frame, and two scissor structures. The lower frame is U-shaped and fixed to the top of the water tank.

The top and bottom right sides of the scissor structures are rotatably connected to the upper and lower frames, respectively. The top and bottom left sides of the scissor structures are slidably engaged with the sliding groove 2 and sliding groove 1, respectively. A connecting rod is fixedly connected between the bottom left sides of the two scissor structures, and the connecting rod is slidably connected to the sliding groove 1. The inner right side wall of the lower frame is fixedly connected to the bottom of the cylinder of cylinder 1. The piston rod end of cylinder 1 is rotatably connected to the connecting rod.

A nozzle 17 is rotatably connected between the two nozzles 17. One end of the nozzle 17 has a narrowed diameter, which is smaller than the other end. The two nozzles 17 are arranged with their smaller diameters facing away from each other. A ring pipe 20 is fixedly connected to the smaller diameter end of the nozzle 17. Several nozzles 21 are fixedly connected to the outer wall of the ring pipe 20. The nozzles 21 are evenly distributed around the ring pipe 20. A water spray connector 22 is fixedly connected to the bottom of the ring pipe 20. A blower 23 is fixedly installed on the inner wall of the larger diameter end of the nozzle 17. The bottom of the nozzle 17 is fixedly connected to the upper part of the connecting rod 18. The connecting rod 18 is close to the smaller diameter end of the nozzle 17. Two cylinders 19 are rotatably connected to the top of the turntable 15. The two cylinders 19 are distributed front and back. The bottom of the cylinder barrel of the two cylinders 19 is rotatably connected to the top of the two turntables 15 respectively. The piston rod ends of the two cylinders 19 are rotatably connected to the bottom of the connecting rod 18 respectively. The connecting rod 18 has an inverted U-shaped structure.
[0018] Two submersible pumps 24 are installed on the inner bottom wall of the water tank 2. The output end of the submersible pump 24 is fixedly connected to a hose 25. The other end of the two hoses 25 is fixedly connected to two water spray connectors 22 respectively. The hoses 25 pass through the top of the water tank 2 and are fixedly connected to the top of the water tank 2.
[0019] The lifting mechanism includes a lower frame 5, an upper frame 6, and two scissor structures 11. The lower frame 5 is U-shaped and fixed to the top of the water tank 2. The upper frame 6 is located above the lower frame 5. The top of the front and rear sides of the lower frame 5 has sliding holes 7, and the front and rear sides of the bottom of the upper frame 6 have sliding holes 8. The front and rear side walls of the lower frame 5 have sliding grooves 9 that communicate with the sliding holes 7. The front and rear side walls of the bottom of the upper frame 6 have sliding grooves 10 that communicate with the sliding holes 8. The two scissor structures 11 are located on the top front and rear sides of the lower frame 5, respectively. The bottom of the blade structure 11 is located in the sliding hole 7, and the top of the scissor structure 11 is located in the sliding hole 8. The top and bottom right sides of the scissor structure 11 are rotatably connected to the upper frame 6 and the lower frame 5, respectively. The top and bottom left sides of the scissor structure 11 are slidably engaged with the sliding groove 10 and the sliding groove 9, respectively.

[0020] The scissor structure 11 is an existing technology device, such as the existing scissor lift, which also uses this structure to achieve the purpose of lifting.
[0021] When carrying out watering operations, first ensure that the water tank 2 is full of water through the inlet 3 and close the cover 4.
[0022] By operating cylinder 13, the cylinder column extends and retracts to push connecting rod 12, which in turn drives the two scissor structures 11 to expand or contract.
[0023] The unfolding and retraction of the scissor structure 11 will cause the upper frame 6 to rise or fall relative to the lower frame 5, thereby adjusting the height of the nozzle 17.
[0024] Start the servo motor 14. The rotation of the servo motor 14 drives the turntable 15 to rotate. The fixed plate 16 and the nozzle 17 on the turntable 15 rotate accordingly, which can adjust the direction of water spray. The rotation angle of the servo motor 14 must be within a certain range to prevent the hose 25 from getting tangled.
[0025] Meanwhile, by adjusting the extension and retraction length of the piston rod of cylinder 2 19, the relative position of connecting rod 2 18 and turntable 15 can be changed, thereby adjusting the tilt angle of nozzle 17.
[0026] The submersible pump 24 is started to draw water from the water tank 2 and deliver it to the spray nozzle 22 through the hose 25. The water enters the spray pipe 17 from the spray nozzle 22 and is sprayed out in a mist from the nozzle 21 by the airflow generated by the fan 23. The nozzles 21 are evenly distributed around the ring pipe 20 to ensure uniform dust suppression spraying. This utility model only protects the mechanical parts; the functions implemented by the software control part are not within the scope of protection of this utility model.
