Technical Field
[0001] This utility model relates to the field of blasting excavation technology, specifically to an environmentally friendly dust suppression device for blasting excavation. Background Technology
[0002] In many engineering construction fields, such as mining, road construction, and large building foundation construction, blasting excavation is a common and efficient construction method. The enormous energy released instantaneously by the explosion of explosives can quickly break up rocks and soil, creating favorable conditions for subsequent engineering operations. However, the blasting process generates a large amount of dust, which, under the impact of the explosion, rapidly spreads in all directions, permeating the construction site and surrounding areas. Therefore, dust suppression measures are necessary.
[0003] In blasting and excavation scenarios such as mining and road construction, most existing dust suppression technologies use fixed sprinkler heads. This method is limited by the fixed installation structure and can only suppress dust in specific areas. It cannot be adjusted according to the dynamic range of dust diffusion after blasting. Therefore, we provide an environmentally friendly dust suppression device for blasting and excavation. Utility Model Content
[0004] The purpose of this utility model is to provide an environmentally friendly dust suppression device for blasting excavation, so as to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: An environmentally friendly dust suppression device for blasting excavation includes an environmentally friendly dust suppression device body, the environmentally friendly dust suppression device body includes a base, the base is provided in two sets, the two sets of bases are provided with mounting holes on all four sides, the top of the two sets of bases are fixedly installed with a rotating shaft, and a bearing rod is rotatably installed inside the rotating shaft.
[0006] A dust-collecting ring is fixedly sleeved on the outer surface of the bearing rod, and a nozzle is fixedly installed on the inner side of the dust-collecting ring.
[0007] A further improvement of this utility model is that a water pump is fixedly installed on the top of the base on the left side, and a water pump pipe is fixedly installed on the pumping end of the water pump. The other end of the water pump pipe is connected to an external water pipe.
[0008] A further improvement of this utility model is that: a drain pipe is fixedly installed at the discharge end of the water pump, and a conveying hose is fixedly installed at the other end of the drain pipe. The other end of the conveying hose is fixedly installed inside the outer side of the dust suppression ring frame. The model of the water pump is ZW50-15-30.
[0009] A further improvement of this utility model is that a protective cover is fixedly installed on the top outer side of the base on the right side, and a bracket is fixedly installed inside the protective cover.
[0010] A further improvement of this utility model is that a servo motor is fixedly installed inside the bracket, and a main gear is fixedly installed on the output end of the servo motor. The model of the servo motor is MHMF042L1U2M.
[0011] A further improvement of this utility model is that a driven gear is meshed above the main gear, and the driven gear is fixedly sleeved on one end of the outer side of the bearing rod.
[0012] A further improvement of this utility model is that: limiting rings are fixedly installed on both sides of the two sets of bases, and the limiting rings have sliding grooves inside. Sliding rods are fixedly installed at the bottom of the inner walls on both sides of the dust collection ring frame, and the sliding rods are slidably connected inside the sliding grooves.
[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1. This utility model provides an environmentally friendly dust suppression device for blasting excavation. By setting up a water pump in conjunction with a water pumping pipe, a drainage pipe and a conveying hose to form a stable water supply channel, it can continuously deliver clean water to the dust suppression ring frame, ensuring that the atomized water curtain is uninterrupted. The dust suppression ring frame, together with the nozzles fixedly installed on its inner side, can form an atomized water curtain, which can directly intercept and moisten the dust generated by blasting, and suppress the spread of dust from the source.
[0014] 2. This utility model provides an environmentally friendly dust suppression device for blasting excavation. A servo motor drives the main gear to rotate, which in turn rotates the meshing driven gear and the fixedly fitted bearing rod. This causes the dust suppression ring frame on the outer surface of the bearing rod to rotate synchronously. Combined with the sliding cooperation of the limiting ring and the sliding rod, the rotation of the dust suppression ring frame is ensured to be smooth and without deviation. The angle of the dust suppression ring frame can be flexibly adjusted according to the actual conditions such as the blasting operation range and the direction of dust diffusion, allowing the atomized water curtain to fully cover the core area of dust diffusion. This effectively solves the problems of limited coverage and numerous dead zones in traditional dust suppression methods, significantly improving dust suppression efficiency and reducing dust pollution to the construction site and surrounding environment.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1
[0018] like Figure 1-5 As shown, this utility model provides an environmentally friendly dust suppression device for blasting excavation, including an environmentally friendly dust suppression device body 1. The environmentally friendly dust suppression device body 1 includes a base 2, and the base 2 is provided in two sets. The two sets of base 2 are provided with mounting holes 21 on all four sides. The top of the two sets of base 2 are fixedly installed with a rotating shaft 3. The rotating shaft 3 is rotatably installed with a bearing rod 4 inside. A dust suppression ring frame 41 is fixedly sleeved on the outer surface of the bearing rod 4. A nozzle 42 is fixedly installed on the inner side of the dust suppression ring frame 41. A water pump 22 is fixedly installed on the top of the left base 2 at the outer side. A water pump pipe 23 is fixedly installed at the liquid pumping end of the water pump 22. The other end of the water pump pipe 23 is connected to an external water pipe. A drain pipe 24 is fixedly installed at the liquid discharge end of the water pump 22. A conveying hose 25 is fixedly installed on the other end of the drain pipe 24. The other end of the conveying hose 25 is fixedly installed inside the outer side of the dust suppression ring frame 41.
[0019] Furthermore, the external water supply pipeline is sealed and connected to the pumping pipe 23 connected to the pumping end of the top water pump 22 on the left base 2 to complete the water supply path. At this time, the PLC sends a start command to the pumping pump 22 and the servo motor 33. After the pumping pump 22 starts, it draws clean water from the external water pipe through the pumping pipe 23. After the clean water is pressurized by the pumping pump 22, it is transported to the delivery hose 25 through the drain pipe 24 at the drain end. Then, it is introduced into the outer interior of the dust suppression ring frame 41 through the delivery hose 25. Finally, it forms an atomized water curtain through the nozzle 42 fixedly installed on the inner side of the dust suppression ring frame 41. Example 2
[0020] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a protective cover 31 is fixedly installed on the top outer side of the right base 2, a bracket 32 is fixedly installed inside the protective cover 31, a servo motor 33 is fixedly installed inside the bracket 32, a main gear 34 is fixedly installed on the output end of the servo motor 33, a driven gear 35 is meshed above the main gear 34, and the driven gear 35 is fixedly sleeved on one end of the outer side of the bearing rod 4.
[0021] Furthermore, when it is necessary to adjust the angle of the dust collection ring frame 41, the servo motor 33 can be started and drive the main gear 34 at the output end to rotate. The main gear 34 drives the driven gear 35 that meshes with it to rotate. The driven gear 35 then drives the fixedly sleeved bearing rod 4 to rotate inside the rotating shaft 3 at the top of the two sets of bases 2. When the bearing rod 4 rotates, it drives the dust collection ring frame 41 that is fixedly sleeved on the outer surface to rotate synchronously, which can be adjusted to the required angle. Example 3
[0022] like Figure 1-5 As shown, based on embodiments 1-2, this utility model provides a technical solution: preferably, limiting rings 26 are fixedly installed on both sides of the two sets of bases 2, and the limiting rings 26 have sliding grooves 27 inside. Sliding rods 43 are fixedly installed at the bottom of the inner walls on both sides of the dust collection ring frame 41, and the sliding rods 43 are slidably connected inside the sliding grooves 27.
[0023] Furthermore, during the rotation of the dust suppression ring frame 41, the sliding rods 43 fixedly installed at the bottom of the inner walls on both sides will slide along the sliding grooves 27 inside the limiting rings 26 fixedly installed on both sides of the two sets of bases 2, so as to ensure that the dust suppression ring frame 41 rotates smoothly and does not deviate. Under the adjustment of the rotation of the dust suppression ring frame 41, the atomized water curtain achieves all-round coverage of the blasting operation area.
[0024] The solution uses a PLC as the core control component. The PLC establishes a connection with the water pump 22 and the servo motor 33 through RS-485 communication. When it is necessary to start the water pump 22 and the servo motor 33, the PLC sends a start command to the water pump 22 and the servo motor 33, causing the water pump 22 and the servo motor 33 to start.
[0025] The working principle of the environmental dust suppression device used in this blasting excavation will be explained in detail below.
[0026] like Figure 1-5As shown, when using this blasting excavation environmental dust suppression device, firstly, through the mounting holes 21 opened around the two sets of bases 2, expansion bolts and other compatible connectors are used to fix the bases 2 to designated stable positions around the blasting working face, while ensuring that the dust suppression ring frame 41 can cover the core area where dust may spread after blasting. Next, the external water supply pipeline is sealed and connected to the water pump 22 at the top of the left base 2, and the water supply path is completed. At this time, the PLC sends a start command to the water pump 22 and the servo motor 33. After the water pump 22 starts, it draws clean water from the external water pipe through the water pump 23. After the clean water is pressurized by the water pump 22, it is transported to the delivery hose 25 through the drain pipe 24 at the discharge end, and then introduced into the outer interior of the dust suppression ring frame 41 through the delivery hose 25, and finally through the water pump 22. The nozzles 42, which are fixedly installed on the inner side of the dust suppression ring frame 41, form an atomized water curtain. When it is necessary to adjust the angle of the dust suppression ring frame 41, the servo motor 33 can be started and drive the main gear 34 at the output end to rotate. The main gear 34 drives the driven gear 35 that meshes with it to rotate. The driven gear 35 then drives the fixedly sleeved bearing rod 4 to rotate inside the rotating shaft 3 at the top of the two sets of bases 2. When the bearing rod 4 rotates, it drives the dust suppression ring frame 41, which is fixedly sleeved on the outer surface, to rotate synchronously. During the rotation of the dust suppression ring frame 41, the sliding rods 43, which are fixedly installed at the bottom of the inner walls on both sides, will slide along the sliding grooves 27 inside the limiting rings 26 fixedly installed on both sides of the two sets of bases 2 to ensure that the dust suppression ring frame 41 rotates smoothly and does not deviate. The atomized water curtain achieves all-round coverage of the blasting operation area under the rotation adjustment action of the dust suppression ring frame 41.
[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
