Description

Technical Field

[0001] This invention belongs to the technical field of road construction dust suppression equipment, and in particular relates to a curbstone cutting dust suppression device for road construction. Background Technology

[0002] Dust suppression devices are needed when cutting curbs during road construction. They can improve the environmental protection effect of curb cutting, prevent dust, and reduce the impact on the environment.

[0003] Because most existing curb stones require on-site cutting to the appropriate size before laying, a large amount of dust is inevitably generated during the cutting process. Current methods for dust suppression involve either placing sprinkler systems around the construction area to control the dust, which inevitably wastes a lot of water, or installing a spray system on the cutting equipment to control dust. However, since the spray system is integrated with the cutting equipment, it is difficult to replace or maintain the spray system after long-term use, and its position on the cutting equipment cannot be adjusted, making it difficult to effectively control the dust generated during curb stone cutting. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0005] This invention relates to a dust suppression device for curbstone cutting in road construction, comprising a mobile trolley. A settling box is fixed to the upper surface of the trolley's base plate. The settling box is divided into a water storage chamber and a dust collection chamber by a partition. A water pump is installed inside the water storage chamber, and the water pump's outlet pipe is connected to a main water supply pipe. A spray settling mechanism is installed on the right side of the main water supply pipe, passing through the water storage chamber. A fan is fixed above the dust collection chamber, and a suction pipe is connected to the right side of the dust collection chamber. A dust collection mechanism is installed at the free end of the suction pipe. The spray settling mechanism and the dust collection mechanism are detachably and synchronously installed on the cutting cover of the curbstone cutting disc to settle the dust generated during curbstone cutting and collect the particulate dust generated during cutting.

[0006] Furthermore, the spray settling mechanism includes a water distribution plate, a guide hose, a rigid clamp, a connecting bend, and a spray head. The water distribution plate is installed at the inlet of the main water supply pipe, and a dispersion chamber is provided inside the water distribution plate. Several guide hoses are fixedly installed on the circumference of the right end face of the water distribution plate, and the several guide hoses are connected to the dispersion chamber. A rigid clamp is fixed on the outer circumference of the inlet of each guide hose away from the water distribution plate, and the inlet of each guide hose is inclined outward and connected to a connecting bend. A spray head is installed at the inlet of each connecting bend.

[0007] Furthermore, the dust collection mechanism includes an air distribution plate, air guide hoses, support tubes, locking blocks, magnets, and a dust collection hood. The air distribution plate is connected to the inlet of the main dust collection pipe, and an air chamber is formed inside the air distribution plate. Several air guide hoses are arranged in a circular array on the right side of the air distribution plate, and the air guide hoses are connected to the air chambers. Each air guide hose has a support tube connected to its inlet away from the air distribution plate, and a locking block is fixed to the outer circumference of each support tube. Magnets are installed on the corresponding circumferential surfaces of several locking blocks to attract and fix the locking blocks to the cutting cover. Each locking block has a locking groove on its outer side, and a rigid locking tube is slidably engaged in each locking groove. A dust collection hood is installed at the inlet of each support tube.

[0008] Furthermore, an external threaded pipe is fixedly connected to the left side of the water distribution plate, and an internal threaded pipe is fixed to the opening of the main water supply pipe. The external threaded pipe is threadedly connected to the internal threaded pipe. A threaded hole is opened on the left side of the air distribution plate, and an external threaded suction pipe is provided at the opening of the main dust suction pipe. The external threaded suction pipe is threadedly connected to the threaded hole, and the diameter of the external threaded suction pipe is the same as the inner diameter of the internal threaded pipe.

[0009] Furthermore, a collection box is slidably inserted into the dust collection chamber. The right side and top of the collection box are respectively provided with a dust suction hole and a suction hole. The right inner wall and the lower top wall of the dust collection chamber are both fixed with elastic sealing tubes, and both elastic sealing tubes adopt a conical structure design. One end of the elastic sealing tube located on the right inner wall is connected to the opening of the dust suction main pipe, and the large diameter opening of the conical elastic sealing tube is squeezed and aligned with the opening of the dust suction hole. The opening of the elastic sealing tube located on the lower top wall is connected to the air duct of the fan, and the large diameter opening of the elastic sealing tube is squeezed and aligned with the opening of the suction hole. A filter screen is installed on the top of the collection box, and the filter screen is located at the opening of the suction hole.

[0010] Furthermore, a dispersion component is provided inside the collection box. The dispersion component includes a support shaft, dispersion blades, a suspension rod, and a bearing. The support shaft is horizontally arranged inside the collection box and aligned with the dust suction hole. Dispersion blades are fixedly sleeved on the support shaft, and a bearing is sleeved on the support shaft, with the bearing located to the left of the dispersion blades. A suspension rod is fixedly attached to the top wall of the collection box and is fixedly connected to the outer ring surface of the bearing.

[0011] Furthermore, the filter cylinder is made of elastic metal material, and the bottom of the filter cylinder is located above the dust suction hole. The support shaft extends to the bottom of the filter cylinder, and a cam block is fixedly sleeved on the support shaft. The protrusion of the cam block rotates and presses against the bottom of the filter cylinder.

[0012] Furthermore, the lower wall of the collection box is horizontally provided with discharge grooves at the front and back, and a strip-shaped sealing plug is sealed and inserted into the discharge groove. Arc-shaped elastic plates are fixedly installed on the left and right sides of the collection box, and the bottom of the arc-shaped elastic plates is connected to the bottom of the collection box. The support shaft extends above the arc-shaped elastic plates, and a cam extrusion plate is fixed at the end of the support shaft away from the dispersing blades. The protrusion of the cam extrusion plate makes rotational extrusion contact with the arc-shaped elastic plates.

[0013] The present invention has the following beneficial effects:

[0014] 1. This invention, through the cooperation of a spray settling mechanism and a dust collection mechanism, along with several guide hoses and several air guide hoses, magnetically attaches multiple dust hoods and multiple spray heads to different positions on the outer surface of the cutting hood. This allows the dust hoods to first draw in and collect the particulate dust generated during cutting, reducing pollution caused by particulate dust around the construction area. Simultaneously, the spray heads can spray water mist around the cutting hood to settle the flying dust, preventing significant water waste. Furthermore, the dust hoods and spray heads are detachable from the cutting hood, facilitating the replacement and maintenance of the spray settling and dust collection mechanisms after prolonged use. The installation positions of the dust hoods and spray heads on the cutting hood can also be adjusted at any time, enabling concentrated suction and settling of dust generated in different locations around the cutting hood, thereby improving the dust settling effect during curbstone cutting.

[0015] 2. The present invention features a collection box that can be pulled out and installed inside the dust collection chamber. The conical elastic sealing tube can be compressed and slidably fitted to the outer side of the collection box. This not only enables the fan duct and the main suction pipe to be sealed and connected to the suction hole and the dust collection hole respectively, thus allowing particulate dust to be sucked into the collection box for collection, but also does not interfere with the collection box being pulled out of the dust collection chamber. This facilitates the quick removal of the collection box from the dust collection chamber to clean up the collected particulate dust.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-7 As shown, the present invention is a dust suppression device for curbstone cutting in road construction, including a mobile cart 1. A settling box 2 is fixed on the upper surface of the bottom plate of the mobile cart 1. The settling box 2 is divided into a water storage tank 21 and a dust collection tank 22 by a partition. A water pump is installed inside the water storage tank 21, and the water outlet pipe of the water pump is connected to a water supply main pipe 3. A spray settling mechanism 4 is installed on the right side of the water storage tank 21 through the water supply main pipe 3. A fan is fixed above the dust collection tank 22, and a dust suction main pipe 5 is connected to the right side of the dust collection tank 22. A dust collection mechanism 6 is installed at the free end of the dust suction main pipe 5. The spray settling mechanism 4 and the dust collection mechanism 6 are detachably installed on the cutting cover of the curbstone cutting disc to settle the dust generated by the cutting of the curbstone and collect the particulate dust generated by cutting.

[0028] In the design of this invention, the settling tank 2 is divided into a water storage tank 21 and a dust collection tank 22. The water storage tank 21 is connected to a spray settling mechanism 4 via a water supply main pipe 3, while the dust collection tank 22 is connected to a dust collection mechanism 6 via a dust suction main pipe 5. When construction workers are cutting the curbstone, they install several air distribution pipes on the dust collection mechanism 6 at different positions on the cutting hood, and then install the water distribution pipes of the spray settling mechanism 4 on the outside of the air distribution pipes. Therefore, when the cutting disc generates dust from cutting the curbstone, the dust collection mechanism 6 first sucks the dust particles generated during cutting into the dust suction main pipe 5 through multiple air distribution pipes, and then into the dust collection tank 22 for collection. At the same time, several water distribution pipes located on the outside spray water mist onto the outside of the cutting hood. The dust generated during cutting is treated to settle, thus the particulate dust produced during curbstone cutting is first absorbed and collected, reducing the pollution caused by particulate dust around the construction area. At the same time, the spray settling mechanism 4 can spray water mist around the cutting cover to settle the flying dust, which not only avoids a large waste of water, but also allows the spray settling mechanism 4 and the dust collection mechanism 6 to be detachably installed on the cutting cover. This makes it easy to replace and maintain the spray settling mechanism 4 and the dust collection mechanism 6 after long-term use. At the same time, the installation position of the spray settling mechanism 4 and the dust collection mechanism 6 on the cutting cover can be adjusted at any time, which makes it easy to concentrate the suction and settling of dust generated in different locations around the cutting cover, thereby improving the dust settling effect generated during curbstone cutting.

[0029] In one embodiment of the present invention, the spray settling mechanism 4 includes a water distribution plate 41, a guide hose 42, a rigid clamping pipe 43, a connecting bend pipe 44, and a spray head 45. The water distribution plate 41 is installed at the inlet of the main water supply pipe 3, and a dispersion chamber 411 is provided inside the water distribution plate 41. A plurality of guide hoses 42 are fixedly installed on the circumference of the right end face of the water distribution plate 41, and the plurality of guide hoses 42 are connected to the dispersion chamber 411. A rigid clamping pipe 43 is fixed on the outer ring surface of the inlet of each guide hose 42 away from the water distribution plate 41, and the inlet of each guide hose 42 is inclined outward and connected to a connecting bend pipe 44. A spray head 45 is installed at the inlet of each connecting bend pipe 44.

[0030] In the design of this invention, when the cutting equipment needs to cut the curbstone, the construction personnel first move the settling equipment to the cutting area, then the dust collection mechanism 6 is installed on the cutting cover, and then several guide hoses 42 are clamped to the dust collection mechanism 6 through rigid clamps 43, so that the spray head 45 at the end of the connecting bend 44 is tilted towards the outside of the cutting cover. The water pump in the water storage tank 21 will inject the spray water into the water distribution plate 41 through the water supply main pipe 3, and then distribute it to multiple guide hoses 42 through the dispersion chamber 411 in the water distribution plate 41. This makes it easier for the spray water to be sprayed in an atomized form to the area around the cutting cover through the spray head 45. This not only enables the settling of the dust generated by cutting, but also eliminates the need for large-area water spraying and settling treatment in the construction area, thereby reducing water waste.

[0031] In one embodiment of the present invention, the dust collection mechanism 6 includes an air distribution plate 61, air guide hoses 62, a support pipe 63, a locking block 64, a magnet 65, and a dust collection hood 66. The air distribution plate 61 is connected to the inlet of the main dust collection pipe 5, and an air chamber 611 is formed inside the air distribution plate 61. A plurality of air guide hoses 62 are arranged in a circular array on the right side of the air distribution plate 61, and the air guide hoses 62 are connected to the air chamber 611. Each air guide hose 62 is located at a distance from the air chamber 61. Each of the air distribution plate 61 has a support pipe 63 connected to its port, and each of the support pipes 63 has a locking block 64 fixed on its outer ring surface. Each of the locking blocks 64 has a magnet 65 installed on its corresponding circumferential surface to attract and fix the locking block 64 to the cutting cover. Each locking block 64 has a locking groove 641 on its outer side, and each locking groove 641 has a rigid locking tube 43 slidably engaged in it. Each of the support pipes 63 has a dust suction cover 66 installed at its port.

[0032] In the design of this invention, after the mobile trolley 1 moves the settling box 2 to the construction area, the construction personnel first inject water into the water storage tank 21 through the water injection hole on the front side. Then, they remove the main suction pipe 5 from the bottom plate of the mobile trolley. The main suction pipe 5 is made of rubber hose material. They pull it to the vicinity of the cutting equipment. Then, several air guide hoses 62 are magnetically attracted to the outer side of the cutting cover by the magnet 65 on the locking block 64. Depending on which part of the cutting cover produces a large amount of dust, multiple air guide hoses 62 are densely installed at that position. The clamping block 64, which is fixed by adsorption, provides gravity support to the air guide hose 62 through the support tube 63. At this time, multiple dust collection hoods 66 are arranged flush with the bottom opening of the cutting hood. Then, the operator presses the rigid clamping tubes 43 on the outer ring of several guide hoses 42 into the clamping grooves 641 opened on the outer side of the clamping block 64, so that the clamping grooves 641 can clamp and fix the rigid clamping tubes 43. This allows the spray head 45, which is inclined and set through the connecting bend 44, to be tilted downwards and located outside the dust collection hood 66. Then, the suction force generated by the fan above the dust collection chamber 22 will pass through the air distribution plate 61 and the air chamber. 611 and several air guide hoses 62 are connected to several fixed dust collection hoods 66, so that the particulate dust generated when the cutting disc inside the cutting hood cuts the curbstone is sucked into the multiple air guide hoses 62, and then enters the dust collection chamber 22 through the air distribution plate 61 and the dust collection main pipe 5. This prevents the particulate dust generated after cutting from accumulating in the construction area, which would not only cause pollution to the surrounding environment, but also make it difficult to collect and treat the dust generated after cutting. The spray head 45 can spray water in an atomized form around the cutting hood to settle the dust that flies after cutting. After the curbstone is cut, the construction workers first remove the rigid clamping tube 43 from the clamping groove 641, so that the guide hose 42 separates from the air guide hose 62 in sequence. Then, the magnet 65 on the clamping block 64 is removed from the cutting cover and fixed by adsorption, which makes it easy to quickly remove the dust suction cover 66 and the spray head 45 from the cutting equipment. This facilitates the collection and settling of dust for the next curbstone to be cut. Moreover, the settling device of the present invention can also be applied to other cutting equipment with cutting covers made of metal materials, so as to achieve efficient collection and settling of dust generated during road construction.

[0033] In one embodiment of the present invention, an external threaded pipe 46 is fixedly connected to the left side of the water distribution plate 41, an internal threaded pipe 47 is fixed to the opening of the water supply main pipe 3, the external threaded pipe 46 is threadedly connected to the internal threaded pipe 47, a threaded hole is opened on the left side of the air distribution plate 61, an external threaded suction pipe 67 is provided at the opening of the dust suction main pipe 5, and the external threaded suction pipe 67 is threadedly connected to the threaded hole, the diameter of the external threaded suction pipe 67 is the same as the inner diameter of the internal threaded pipe 47;

[0034] In the design of this invention, the water distribution plate 41, through the cooperation of the external threaded pipe 46 and the internal threaded pipe 47, allows the main water supply pipe 3 to be disassembled, thereby facilitating the disassembly of the spray settling mechanism 4 from the main water supply pipe 3 and enabling the replacement of any damaged components in the spray settling mechanism 4. Meanwhile, the dust suction pipe 5, connected to the threaded hole on the air distribution plate 61 via the external threaded suction pipe 67, allows for the disassembly and connection of the dust suction pipe 5 to the dust collection mechanism 6. This not only facilitates the replacement of any damaged components in the dust collection mechanism 6 but also allows for the removal and replacement of dust accumulated within the air distribution plate 61. The particulate dust is cleaned and discharged. After the water supply main pipe 3 is disassembled from the water distribution plate 41, and the dust suction main pipe 5 and the air distribution plate 61 are disassembled, the construction personnel can connect the external threaded air suction pipe 67 to the internal threaded pipe 47. The water supply main pipe 3 and the dust suction main pipe 5 are connected. Then, the construction personnel can use the water pump and the water supply main pipe 3 to introduce water into the dust suction main pipe 5. The water source can not only clean the dust suction main pipe 5 and prevent particulate dust from clogging the dust suction main pipe 5, but also clean the dust collection chamber 22, so as to facilitate the rapid cleaning and discharge of particulate dust collected in the dust collection chamber 22.

[0035] In one embodiment of the present invention, a collection box 7 is slidably inserted into the dust collection chamber 22. The collection box 7 has a dust suction hole 71 and a suction hole 72 respectively opened on the right side and top. An elastic sealing tube 74 is fixed on the right inner wall and the top lower wall of the dust collection chamber 22. Both elastic sealing tubes 74 adopt a conical structure design. One end of the elastic sealing tube 74 located on the right inner wall is connected to the opening of the dust suction main pipe 5. The large diameter opening of the conical elastic sealing tube 74 is squeezed and aligned with the opening of the dust suction hole 71. The opening of the elastic sealing tube 74 located on the top lower wall is connected to the air duct of the fan. The large diameter opening of the elastic sealing tube 74 is squeezed and aligned with the opening of the suction hole 72. A filter screen cylinder 75 is installed on the top of the collection box 7. The filter screen cylinder 75 is located at the opening of the suction hole 72.

[0036] In the design of this invention, to facilitate the collection and removal of particulate dust collected in the dust collection chamber 22, when the collection box 7 is inserted into the dust collection chamber 22, its top and right side walls will contact the conical elastic sealing tube 74 on the top and right side walls of the dust collection chamber 22. This causes the conical elastic sealing tube 74 to compress against the top and right side walls of the collection box 7. When the collection box 7 is fully inserted into the dust collection chamber 22, the large-diameter opening of the top conical elastic sealing tube 74 will press and seal against the outer opening of the suction hole 72, while the large-diameter opening of the right side conical elastic sealing tube 74 will press and seal against the outer opening of the suction hole 71. This allows the suction hole 71 to be sealed and connected to the main suction pipe 5 through the elastic sealing tube 74, and the suction hole 72 to be sealed and connected to the fan duct through the elastic sealing tube 74. The suction force generated by the fan will then act on the dust collection hood 66 through the collection box 7, the main suction pipe 5, and the air guide hose 62. Once the collection box 7 has collected a certain amount of particulate dust, the construction personnel stop the dust suppression equipment and pull the collection box 7 outwards, causing the two elastic sealing tubes 74 to detach from the suction hole 71 and the extraction hole 72. When the collection box 7 is completely detached from the dust collection chamber 22, the elastic sealing tubes 74 will detach from the outer surface of the collection box 7. The conical elastic sealing tubes 74 can compress and slide against the outer surface of the collection box 7, which not only seals and connects the fan duct and the main suction pipe 5 to the extraction hole 72 and the suction hole 71 respectively, thus allowing the particulate dust to be drawn into the collection box 7 for collection, but also does not interfere with the collection box 7 being pulled out of the dust collection chamber 22. This facilitates the quick removal of the collection box 7 from the dust collection chamber 22 to clean up the collected particulate dust. The filter screen 75 installed at the extraction hole 72 can filter the particulate dust drawn into the collection box 7, preventing the particulate dust from passing through the extraction hole 72 and the elastic sealing tubes 74 into the fan.

[0037] In one embodiment of the present invention, a dispersing component 8 is provided inside the collection box 7. The dispersing component 8 includes a support shaft 81, a dispersing blade 82, a suspension rod 83, and a bearing 84. The support shaft 81 is horizontally arranged inside the collection box 7 and is aligned with the dust suction hole 71. The dispersing blade 82 is fixedly sleeved on the support shaft 81, and the bearing 84 is sleeved on the support shaft 81 and is located to the left of the dispersing blade 82. The suspension rod 83 is fixedly connected to the outer ring surface of the bearing 84 on the top wall of the collection box 7.

[0038] In the design of this invention, when particulate dust enters the collection box 7 through the dust suction hood 66, the air guide hose 62, the air distribution plate 61, and the dust suction main pipe 5, the dispersing blades 82 aligned with the dust suction hole 71 will rotate inside the collection box 7 under the drive of the flowing gas and the mixed particulate dust. The rotating dispersing blades 82 will disperse the particulate dust entering the collection box 7, preventing the particulate dust sucked into the collection box 7 from directly accumulating on the outer wall or below the filter screen cylinder 75. At the same time, the rotating dispersing blades 82 can also break and disperse the sucked-in large particulate dust, thereby preventing large particulate dust from directly impacting the filter screen cylinder 75 and causing damage.

[0039] In one embodiment of the present invention, the filter cylinder 75 is made of elastic metal material, and the bottom of the filter cylinder 75 is located above the dust suction hole 71. The support shaft 81 extends to the bottom of the filter cylinder 75, and a cam block 85 is fixedly sleeved on the support shaft 81. The protrusion of the cam block 85 rotates and presses against the bottom of the filter cylinder 75.

[0040] In the design of this invention, when the dispersing blade 82 rotates inside the collection box 7, the dispersing blade 82 will drive the support shaft 81 to rotate synchronously and slowly. Since the support shaft 81 is fixed with a cam block 85 and the cam block 85 is located below the filter screen cylinder 75 made of elastic metal material, the rotation of the support shaft 81 will drive the cam block 85 to rotate. As a result, when the protrusion of the cam block 85 rotates, it will squeeze and knock the bottom surface of the filter screen cylinder 75, which will facilitate the knocking off of the particulate dust adhering to the filter screen cylinder 75, preventing the particulate dust from clogging the mesh of the filter screen cylinder 75, thereby affecting the normal suction of particulate dust generated by the dust collection mechanism 6, and thus affecting the dust collection and settling effect generated after the curbstone is cut.

[0041] In one embodiment of the present invention, the lower wall of the collection box 7 is provided with a discharge groove 73 horizontally at the front and back, and a strip-shaped sealing plug 9 is sealed and inserted into the discharge groove 73. Arc-shaped elastic plates 10 are fixedly installed on the left and right sides of the collection box 7, and the bottom of the arc-shaped elastic plate 10 is connected to the bottom of the collection box 7. The support shaft 81 extends above the arc-shaped elastic plate 10, and a cam extrusion plate 86 is fixed at the end of the support shaft 81 away from the dispersing blade 82. The protrusion of the cam extrusion plate 86 makes rotational extrusion contact with the arc-shaped elastic plate 10.

[0042] In the design of this invention, arc-shaped elastic plates 10 are provided on the left and right side walls of the collection box 7. These plates can guide the particulate dust sucked into the collection box 7 to the middle of the collection box 7. When the support shaft 81 rotates, the protrusion of the cam extrusion plate 86 rotates downward and squeezes and knocks the arc-shaped elastic plate 10. This knocks the particulate dust accumulated on the surface of the arc-shaped elastic plate 10 and causes it to slide down to the bottom of the collection box 7. After the collection box 7 is removed, the strip-shaped sealing plug 9 at the bottom is opened, and the particulate dust collected in the middle is discharged from the outside of the collection box 7 through the discharge chute 73. This facilitates the cleaning of the particulate dust collected in the collection box 7. At the same time, the water source filled into the collection box 7 will also rinse the arc-shaped elastic plate 10, thus eliminating the need for construction personnel to manually clean the particulate dust collected inside the collection box 7.

[0043] Working principle:

[0044] After the mobile trolley 1 moves the settling box 2 to the construction area, the construction personnel first inject water into the water storage tank 21 through the water injection hole on the front side. Then, they remove the main suction pipe 5 from the bottom plate of the mobile trolley. The main suction pipe 5 is made of rubber hose. They pull it to the vicinity of the cutting equipment. Then, several air guide hoses 62 are magnetically attracted to the outside of the cutting cover by the magnets 65 on the locking block 64. Depending on which part of the cutting cover produces the most dust, multiple air guide hoses are... The 62 are densely installed in this position, and the magnetic attraction 65 and the locking block 64, which are fixed by magnetic attraction, will provide gravity support for the air guide hose 62 through the support tube 63. At this time, multiple dust collection hoods 66 are arranged and are flush with the bottom opening of the cutting hood. Then, the operator presses the rigid clamping tubes 43 on the outer surface of several air guide hoses 42 into the locking grooves 641 opened on the outer side of the locking block 64, so that the locking grooves 641 can lock and fix the rigid clamping tubes 43, thereby facilitating the spraying of the inclined setting of the connecting bend pipe 44. The spray nozzle 45 is positioned at an angle downwards outside the dust collection hood 66. The suction force generated by the fan above the dust collection chamber 22 is then applied through the air distribution plate 61, air chamber 611, and several air guide hoses 62 to several fixed dust collection hoods 66. This facilitates the intake of particulate dust generated when the cutting disc inside the cutting hood cuts the curbstone into multiple air guide hoses 62, and then through the air distribution plate 61 and the main suction pipe 5 into the dust collection chamber 22. The spray nozzle 45 also atomizes the water source into a mist. The dust is sprayed around the cutting hood to settle the dust that flies up after cutting. After the curbstone is cut, the construction workers first remove the rigid clamp 43 from the clamping groove 641, so that the guide hose 42 separates from the air guide hose 62 in turn. Then, the magnet 65 on the clamping block 64 is removed from the cutting hood and fixed, which makes it easy to quickly remove the dust suction hood 66 and the spray head 45 from the cutting equipment, so as to facilitate the collection and settling of dust for the next curbstone to be cut.
