Description

Technical Field

[0001] This utility model relates to the field of demolition equipment technology, and in particular to an automatic dust suppression device for demolition. Background Technology

[0002] During demolition operations, the removal, breaking, and transportation of buildings will generate particulate dust from building materials such as concrete, bricks, and wood. When demolishing buildings using machinery or manual labor, the wall and ground structures will be damaged, turning the originally fixed building materials into small pieces or powder. These small pieces and powder will form dust under the action of gravity and external forces. For example, when an excavator demolishes a wall, the collapse and breakage of the wall will generate a large amount of dust.

[0003] However, traditional equipment dismantling lacks dust removal mechanisms, generating a large amount of dust during the process. Without dust removal, the dust will spread unimpeded into the surrounding environment, causing a sharp decline in air quality. This not only affects the health of construction workers but also seriously disrupts the lives of nearby residents, such as causing respiratory diseases and affecting their normal travel and outdoor activities. The location and range of dust generation at the demolition site are complex and variable. If the angle of the water spraying mechanism is fixed, it is difficult to fully cover all dust-generating areas. This can result in some areas being sprayed with excessive water while others fail to achieve effective dust suppression, thus reducing the effectiveness of water spraying for dust suppression. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic dust suppression device for demolition, which can solve the problem that traditional devices lack dust removal mechanisms during demolition. A large amount of dust is generated during the demolition process. Without a dust removal mechanism, the dust will spread into the surrounding environment without hindrance, causing a sharp decline in air quality. This not only affects the health of construction workers, but also seriously interferes with the lives of nearby residents, such as causing respiratory diseases and affecting residents' normal travel and outdoor activities. The location and range of dust generation at the demolition site are complex and variable. If the angle of the water spraying mechanism is fixed, it is difficult to fully cover all dust-generating areas. There will be situations where some areas are sprayed with excessive water, while other areas cannot be effectively dusted, thus reducing the effectiveness of water spraying for dust suppression.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic dust suppression device for demolition, including an excavator arm and a dust removal mechanism disposed on the outer side of the end of the excavator arm;

[0006] The dust removal mechanism includes a first rotating arm rotatably connected to the outer sides of both ends of the excavating arm. A first gear is fixedly connected to the outer side of one end of the first rotating arm. A first connecting plate is rotatably connected to one side of the first gear. A third rotating arm is rotatably connected to the outer side of one end of the first connecting plate. A second gear is fixedly connected to one side of the third rotating arm. The first gear and the second gear are meshed together. A limit plate is rotatably connected to one side of the first rotating arm. A second rotating arm is rotatably connected to the outer side of one end of the limit plate. A third gear is fixedly connected to one side of the second rotating arm. A second connecting plate is rotatably connected to one side of the third gear. A fourth rotating arm is rotatably connected to one side of the second connecting plate. A fourth gear is fixedly connected to one side of the fourth rotating arm. The third gear and the fourth gear are meshed together. A sliding plate is rotatably connected to one side of the third and fourth rotating arms. A water spray assembly is provided on one side of the sliding plate.

[0008] In a preferred embodiment, a first motor is mounted on one side of the excavating arm, and the outer side of the main shaft of the first motor is fixedly connected to one side of the first rotating arm.

[0009] In a preferred embodiment, two sets of first slide rails are installed on the outer side of one end of the excavator arm, and the slide plate moves through the first slide rails.

[0010] In a preferred embodiment, the water spray assembly includes a mounting plate fixedly connected to one side of the slide plate, an adjusting plate rotatably connected to the outer end of the mounting plate, and multiple sets of water spray strips mounted on one side of the adjusting plate.

[0011] In a preferred embodiment, a second motor is mounted on one side of the mounting plate. A threaded rod is fixedly connected to the outer side of the main shaft of the second motor. A rod sleeve is threadedly connected to the outer side of the end of the threaded rod. Support arms are rotatably connected to the outer sides of both ends of the rod sleeve. The outer side of the end of the support arm is rotatably connected to the inner side of one end of the adjusting plate.

[0012] In a preferred embodiment, a second slide rail is mounted on one side of the mounting plate, and the rod sleeve moves relative to the mounting plate via the second slide rail.

[0013] In a preferred embodiment, the water spray bar has a strip-shaped structure, and two sets of the water spray bar are arranged on both sides of the excavator arm.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In use, this utility model starts by starting the first motor to drive the first rotating arm to rotate, which in turn drives the first gear, the second gear, and the third rotating arm in sequence. Then, through the limiting plate, the third gear, and the fourth gear, the fourth rotating arm is driven to rotate synchronously with the third rotating arm. Finally, the fourth rotating arm and the third rotating arm pull and push the slide plate, which can flexibly adjust the position of the water spray component on one side of the slide plate to meet the dust removal needs of different areas and ensure full coverage of the dust-generating area. The presence of the first slide rail makes the excavator arm and the slide plate slide more smoothly, ensuring smooth cooperation of each component during the operation of the device, reducing jamming and wear, and improving the stability and efficiency of the device.

[0016] 2. In use, this utility model, by starting the second motor to drive the threaded rod to rotate, pushes the support arm through the rod sleeve, and can push and pull the adjustment plate, thereby flexibly adjusting the angle of the adjustment plate. According to the dust distribution at the demolition site, the angle of the suppression device can be precisely adjusted to better target the dust source. The second slide rail makes the rod sleeve slide more smoothly, ensuring stable operation of the device, reducing friction loss between components, reducing the probability of failure, and enabling the device to work continuously and efficiently. The strip-shaped water spray strip has a larger spray range, which can cover a larger area of ​​the demolition area, improve dust suppression efficiency, and more comprehensively suppress dust diffusion.

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.

[0025] Please see Figure 1 - Figure 4 This utility model provides a technical solution: an automatic dust suppression device for demolition, including an excavator arm 1, and a dust removal mechanism 2 disposed on the outer side of the end of the excavator arm 1. The dust removal mechanism 2 includes a first rotating arm 21, which is rotatably connected to the outer sides of both ends of the excavator arm 1. A first gear 22 is fixedly connected to the outer side of one end of the first rotating arm 21. A first connecting plate 23 is rotatably connected to one side of the first gear 22. A third rotating arm 25 is rotatably connected to the outer side of one end of the first connecting plate 23. A second gear 26 is fixedly connected to one side of the third rotating arm 25. The first gear 22 and the second gear 26 are meshed. A limiting plate 221 is rotatably connected to one side of the first rotating arm 21. A second rotating arm 24 is rotatably connected to the outer side of one end of the limiting plate 221. A first gear 26 is fixedly connected to one side of the second rotating arm 24. Three gears 27, a second connecting plate 28 is rotatably connected to one side of the third gear 27, a fourth rotating arm 29 is rotatably connected to the outer side of one end of the second connecting plate 28, a fourth gear 222 is fixedly connected to one side of the fourth rotating arm 29, the third gear 27 and the fourth gear 222 are meshed together, a slide plate 210 is rotatably connected to one side of the third rotating arm 25 and the fourth rotating arm 29, a water spray assembly is provided on one side of the slide plate 210, the first rotating arm 21 and the second rotating arm 24 are arranged in parallel, the third rotating arm 25 and the fourth rotating arm 29 are arranged in parallel, a first motor 212 is installed on one side of the excavating arm 1, the outer side of the main shaft of the first motor 212 is fixedly connected to one side of the first rotating arm 21, two sets of first slide rails 211 are installed on the outer side of one end of the excavating arm 1, and the slide plate 210 moves through the first slide rails 211.

[0026] When a user needs to use the device to remove dust from a designated area, the user can start the first motor 212. The first motor 212 drives one side of the first rotating arm 21 to rotate, which in turn drives the first gear 22 to perform circular motion. At the same time, under the action of the first connecting plate 23, the first gear 22 and the second gear 26 are tightly meshed, which in turn drives the second gear 26 to rotate to a certain extent. The second gear 26 drives the third rotating arm 25 to rotate. At the same time, the limiting plate 221 can push the outer side of one end of the second rotating arm 24 to rotate, which drives the fourth rotating arm 29 and the third rotating arm 25 to rotate synchronously through the third gear 27 and the fourth gear 222. The parallel fourth rotating arm 29 and the third rotating arm 25 can then pull and push the slide plate 210, thereby adjusting the water spray component on one side of the slide plate 210. The position of the water spray component on one side of the slide plate 210 can be flexibly adjusted to meet the dust removal needs of different areas, ensuring full coverage of the dust-generating area. The presence of the first slide rail 211 makes the sliding of the excavator arm 1 and the slide plate 210 smoother. By starting the first motor 212, the first rotating arm 21 is driven to rotate, which in turn drives the first gear 22, the second gear 26, and the third rotating arm 25. Then, through the limit plate 221, the third gear 27, and the fourth gear 222, the fourth rotating arm 29 and the third rotating arm 25 are driven to rotate synchronously. Finally, the fourth rotating arm 29 and the third rotating arm 25 pull and push the slide plate 210, which can flexibly adjust the position of the water spray component on one side of the slide plate 210 to meet the dust removal needs of different areas and ensure full coverage of the dust-generating area. The presence of the first slide rail 211 makes the sliding of the excavator arm 1 and the slide plate 210 smoother, ensuring smooth cooperation of various components during the operation of the device, reducing jamming and wear, and improving the working stability and efficiency of the device.

[0027] like Figure 1 - Figure 4 As shown, the water spray assembly includes a mounting plate 213, which is fixedly connected to one side of the slide plate 210. An adjusting plate 214 is rotatably connected to the outer end of the mounting plate 213. Multiple sets of water spray strips 215 are installed on one side of the adjusting plate 214. A second motor 216 is installed on one side of the mounting plate 213. A threaded rod 217 is fixedly connected to the outer side of the main shaft of the second motor 216. A rod sleeve 218 is threadedly connected to the outer end of the threaded rod 217. Support arms 219 are rotatably connected to the outer ends of both ends of the rod sleeve 218. The outer end of the support arm 219 is rotatably connected to the inner end of one end of the adjusting plate 214. A second slide rail 220 is installed on one side of the mounting plate 213. The rod sleeve 218 moves relative to the mounting plate 213 through the second slide rail 220. The water spray strips 215 are strip-shaped structures, and two sets of water spray strips 215 are arranged on both sides of the excavator arm 1.

[0028] When using the device, the user can start the second motor 216, which drives the threaded rod 217 on the outer side of its main shaft to rotate. This, in turn, pushes one end of the support arm 219 through the rod sleeve 218, thereby pushing and pulling the adjustment plate 214 through the other end of the support arm 219, thus adjusting the angle of the adjustment plate 214 accordingly. The presence of the second slide rail 220 makes the rod sleeve 218 slide more smoothly, and at the same time, the spray range of the strip-shaped water spray strip 215 is larger. By starting the second motor 216 to drive the threaded rod 217 to rotate, the rod... The sleeve 218 pushes the support arm 219, which can push and pull the adjustment plate 214, thereby flexibly adjusting the angle of the adjustment plate 214. According to the dust distribution at the demolition site, the angle of the suppression device can be precisely adjusted to better target the dust source. The second slide rail 220 makes the sleeve 218 slide more smoothly, ensuring stable operation of the device, reducing friction loss between components, reducing the probability of failure, and enabling the device to work continuously and efficiently. The strip-shaped water spray strip 215 has a larger spray range, which can cover a larger area of ​​the demolition area, improve dust suppression efficiency, and more comprehensively suppress dust diffusion.

[0029] Working principle: When a user needs to use this device to remove dust from a designated area, the user can start the first motor 212. The first motor 212 drives one side of the first rotating arm 21 to rotate, which in turn drives the first gear 22 to perform circular motion. At the same time, under the action of the first connecting plate 23, the first gear 22 and the second gear 26 mesh tightly, which in turn drives the second gear 26 to rotate to a certain extent. This drives the third rotating arm 25 to rotate. Simultaneously, the limiting plate 221 can push the outer side of one end of the second rotating arm 24 to rotate, which drives the fourth rotating arm 29 to rotate synchronously with the third rotating arm 25 through the third gear 27 and the fourth gear 222. This, in turn, drives the fourth rotating arm 29 to rotate synchronously with the third rotating arm 25. The fourth rotating arm 29 and the third rotating arm 25, arranged in a row, pull and push the slide plate 210, thereby adjusting the position of the water spray assembly on one side of the slide plate 210 to flexibly adjust the water spray range. Simultaneously, the presence of the first slide rail 211 makes the sliding of the excavator arm 1 and the slide plate 210 smoother. By starting the first motor 212, the first rotating arm 21 rotates, which in turn drives the first gear 22, the second gear 26, and the third rotating arm 25 in sequence. Then, through the limit plate 221, the third gear 27, and the fourth gear 222, the fourth rotating arm 29 and the third rotating arm 25 rotate synchronously. Finally, the fourth rotating arm 29 and the third rotating arm 25 pull and push the slide plate 210, allowing for flexible adjustment of the water spray assembly on one side of the slide plate 210. The device is positioned to meet the dust removal needs of different areas, ensuring comprehensive coverage of dust-generating areas. The presence of the first slide rail 211 makes the sliding of the excavator arm 1 and the slide plate 210 smoother, ensuring smooth cooperation of all components during device operation, reducing jamming and wear, and improving the stability and efficiency of the device. When using the device, the user can start the second motor 216, which drives the threaded rod 217 on the outside of its main shaft to rotate. This, in turn, pushes one end of the support arm 219 through the rod sleeve 218, thereby pushing and pulling the adjusting plate 214 through the other end of the support arm 219, thus adjusting the angle of the adjusting plate 214 accordingly. The presence of the second slide rail 220 makes the sliding of the rod sleeve 218 even smoother. The second slide rail 220 makes the slide of the rod sleeve 218 smoother, ensuring stable operation of the device, reducing frictional wear between components, lowering the probability of failure, and enabling the device to work continuously and efficiently. The strip-shaped water spray bar 215 has a larger spray range, covering a larger demolition area, improving dust suppression efficiency, and more comprehensively suppressing dust diffusion.
