Description

Technical Field

[0001] This invention relates to the field of road surface breaking equipment technology, specifically to a low-noise old road surface demolition equipment. Background Technology

[0002] Old road surface demolition equipment is a core component of road renovation and reconstruction projects. Its core function is to dismantle the old road surface structure through methods such as crushing and milling, laying the foundation for new road paving. This type of equipment is widely used in various road reconstruction scenarios, including municipal roads, highways, and rural roads. It mainly includes various types such as hydraulic breakers, milling machines, and hydraulic picks. Its operational efficiency and environmental performance directly affect the construction progress, the quality of the surrounding environment, and the health of operators, playing a vital role in ensuring the smooth progress of road reconstruction projects.

[0003] Currently, existing technologies for demolishing old roads mostly involve installing breaker posts at the end of excavators to break up the road surface. Most existing breakers are single breaker posts without noise reduction mechanisms, making it impossible to absorb and reduce noise during road demolition. The high-intensity impact noise generated by the breaking operation often far exceeds environmental protection standards, causing noise pollution and seriously interfering with the normal activities of nearby residents, schools, hospitals, and other medical facilities. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a low-noise old road surface demolition equipment, which solves the problems mentioned in the background art.

[0015] This invention provides a low-noise old road surface demolition equipment. Compared with the prior art, it has the following advantages: 1. When demolishing old road surfaces, the upper and lower shells of the noise reduction component can form a cover structure, which is fitted onto the outside of the demolition column. Together with the noise reduction cotton board in the installation groove, it can effectively absorb the noise generated by the demolition and reduce noise pollution. Two sets of observation components allow for observation of the internal working status when the noise reduction component is closed, improving operational convenience. In addition, the dust suction and cleaning component sucks the dust in the connecting shell into the connecting shell and removes it. At the same time, it wipes and cleans the observation components to ensure the clarity of the image captured by the observation components, further improving operational convenience. The drive rod can adjust the height of the lower shell to adapt to the noise reduction requirements of different demolition depths. 2. By setting up a dust filter component, when the air circulates, it drives the dust into the connecting shell, sucking the dust into the interior of the connecting shell. The air passes through the opening and is discharged through the vent. During this process, the dust filter component filters the dust in the air, so that the dust remains in the connecting shell, effectively preventing the dust from being directly emitted into the ambient air and reducing the reduction of ambient air quality, thus reducing dust pollution to the environment. 3. By setting up dust removal components, when the shaft rotates, two sets of dust removal components clean the dust on the surface of the sponge block, achieving a cleaning effect on the sponge block, which is beneficial for the subsequent cleaning of the transparent cover by the sponge block.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, 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.

[0019] To address the technical problems in the background section, the following low-noise old road surface demolition equipment is provided: Combination Figures 1-12 As shown, the present invention provides a low-noise old road surface demolition construction equipment, comprising: Connecting arm 1, with a vertically shaped crushing column 11 installed at the bottom of connecting arm 1, and connecting blocks 12 integrally formed on both sides of connecting arm 1; The noise reduction component 2 is sleeved on the outside of the crushing column 11 and connected to two connecting blocks 12. The noise reduction component 2 includes a mounting base 21, an upper shell 22, a drive rod 23, a lower shell 24, and a noise reduction cotton board 25. Mounting bases 21 that fit against the bottom of the connecting arm 1 are symmetrically installed on the two connecting blocks 12. The upper shell 22 is symmetrically fixedly installed on the bottom of the two mounting bases 21. The two upper shells 22 are fitted together on their respective sides. The drive rods 23 that are vertically oriented are symmetrically installed on the bottom of the upper shells 22. The piston rods of the two drive rods 23 are fixedly installed with the lower shells 24 that are movably sleeved on their outside. The top of the lower shell 24 is movably sleeved on the outside of the upper shell 22 and fits against the cross section of the upper shell 22. Mounting grooves are opened in both the upper shell 22 and the lower shell 24. Noise reduction cotton boards 25 are fixedly installed on both the upper shell 22 and the lower shell 24 and located in the mounting grooves. The observation component 3 is installed in two sets. Both sets of observation components 3 are installed at the bottom of the mounting base 21 and located on both sides of the crushing column 11. The observation component 3 is used to observe the working status of the inner side of the two lower housings 24. The dust removal component 4 includes a connecting shell 41 and a dust suction and cleaning component 42. A connecting hole 221 is provided at the top of the upper shell 22. The connecting shell 41 is fixedly installed on the upper shell 22 and inside the connecting hole 221. The dust suction and cleaning component 42 is installed inside the connecting shell 41. The dust suction and cleaning component 42 is used to suck the dust in the noise reduction component 2 into the connecting shell 41 and discharge it through the connecting shell 41. The dust suction and cleaning component 42 also wipes and cleans the observation component 3.

[0020] When demolishing old road surfaces, the upper and lower shells of the noise reduction component can form a cover structure, which is fitted onto the outside of the demolition column. Together with the noise reduction cotton board in the installation groove, it can effectively absorb the noise generated by the demolition and reduce noise pollution. The two sets of observation components make it easy to observe the internal working status of the noise reduction component when it is closed, which improves the convenience of operation. In addition, the dust suction and cleaning component 42 sucks the dust in the connecting shell 41 into the connecting shell and removes it. At the same time, it wipes and cleans the observation component 3 to ensure the clarity of the image captured by the observation component 3, which further improves the convenience of operation. The drive rod 23 can adjust the height of the lower shell 24 to adapt to the noise reduction requirements of different demolition depths.

[0021] Combination Figures 1-12 As shown, the observation component 3 includes a bracket 31, an industrial camera 32, a transparent cover 33, connecting wires 34, and a display screen 35. The bracket 31 is fixedly installed at the bottom of the mounting base 21, the industrial camera 32 is fixedly installed at the bottom of the bracket 31, and a transparent cover 33 is fixedly installed at the bottom of the bracket 31, covering the outside of the industrial camera 32. Connecting wires 34 are installed on the industrial camera 32, passing through the mounting base 21, and the ends of the two connecting wires 34 are connected to the display screen 35. Specifically, the display screen 35 is used to be installed in the cab of the excavator. In use, the two industrial cameras 32 capture the scene below the crushing column 11 in real time and transmit it to the display screen 35 for display. The operator can observe the position of the crushing column 11 through the display screen 35.

[0022] Combination Figures 1-12 As shown, the vacuum cleaning component 42 includes an air extraction component 421 installed inside the connecting shell 41. One end of the air extraction component 421 is fitted with a cleaning component 422 that contacts the transparent cover 33. The air extraction component 421 includes a vertical plate 4211 fixedly installed on the top wall inside the connecting shell 41. A horizontally oriented rotating shaft 4212 is rotatably mounted on the vertical plate 4211. A vent hole 411 is provided at the end of the connecting shell 41 away from the upper shell 22. One end of the rotating shaft 4212 extends into the vent hole 411 and is coaxially fixedly connected to a fan blade 4213. A motor is fixedly mounted on the vertical plate 4211. The output shaft of the motor is connected to the rotating shaft via a bevel gear assembly 4214. The cleaning component 422 is connected to the rotating shaft 4212. When in use, the control motor is turned on, and the rotating shaft 4212 is driven to rotate on the upright plate 4211 through the bevel gear assembly 4214. This drives the fan blade 4213 to rotate around the rotating shaft 4212, drawing the air out of the connecting shell 41 and discharging it out through the vent 411. External air flows into the inner side of the cover structure through the two upper shells 22 and the two lower shells 24. When the air flows, it carries dust into the connecting shell 41, sucking the dust into the interior of the connecting shell 41. The air passes through the notch 412 and is discharged through the vent 411, achieving the purpose of guiding the airflow.

[0023] Combination Figures 1-12 As shown, the cleaning component 422 includes a rotating rod 4221 that is vertically rotatably mounted on the inner top wall of the communicating shell 41. The rotating rod 4221 is connected to the rotating shaft 4212 via a bevel gear assembly 4222. A connecting frame 4223 with a U-shaped longitudinal section is fixedly mounted on the inner top wall of the communicating shell 41 near the support 31. A sliding plate 4224 is slidably mounted horizontally on the bottom of the connecting frame 4223. One end of the sliding plate 4224 extends to the bottom of the transparent cover 33 and is fixedly mounted with a sponge block 4225 that fits against the inside of the transparent cover 33. A turntable 4226 is coaxially fixedly connected to the bottom of the rotating rod 4221. A connecting shaft 4227 is fixedly mounted at an eccentric position on the bottom of the turntable 4226. The other end extends below the turntable 4226 and is slidably hinged to the connecting shaft 4227. In use, when the rotating shaft 4212 rotates on the upright plate 4211, it drives the rotating rod 4221 to rotate inside the connecting shell 41 through the bevel gear assembly 4222. The turntable 4226 rotates around the rotating rod 4221, and the connecting shaft 4227 makes cylindrical motion around the turntable 4226. The connecting shaft 4227 rotates with the sliding plate 4224, and the connecting shaft 4227 slides on the sliding plate 4224, causing the sliding plate 4224 to slide horizontally back and forth on the bottom plate of the connecting frame 4223. This causes the sponge block 4225 to move horizontally back and forth, thus wiping the bottom plate of the transparent cover 33 and keeping the bottom of the transparent cover 33 clean.

[0024] Combination Figures 1-12 As shown, dust removal components 5 are installed at the bottom of the bracket 31 and on both sides of the transparent cover 33, which act on the sponge block 4225. Both sets of dust removal components 5 are connected to the rotating shaft 4212. When the rotating shaft 4212 rotates, the dust on the surface of the sponge block 4225 is cleaned by the two sets of dust removal components 5. By setting the dust removal components 5, when the rotating shaft 4212 rotates, the dust on the surface of the sponge block 4225 is cleaned by the two sets of dust removal components 5, thus achieving a cleaning effect on the sponge block 4225, which is beneficial for the subsequent cleaning of the transparent cover 33 by the sponge block 4225.

[0025] Combination Figures 1-12As shown, the dust removal component 5 includes a fixed frame 51 fixedly installed at the bottom of the bracket 31 and located on one side of the transparent cover 33. A horizontally oriented rotating shaft 52 is rotatably installed on the fixed frame 51. A brush roller 53 that can contact the sponge block 4225 is fixedly installed on the rotating shaft 52 and located inside the fixed frame 51. The rotating shaft 52 and the rotating shaft 4212 are connected by a transmission component 54. In this embodiment, the transmission component 54 adopts a belt and pulley transmission assembly. When in use, when the rotating shaft 4212 rotates on the upright plate 4211, the two rotating shafts 52 are driven to rotate by the two sets of transmission components 54 respectively. The two brush rollers 53 rotate around the two rotating shafts 52 on both sides of the transparent cover 33. When the sponge block 4225 moves to the outside of the transparent cover 33, it contacts the bristles of the brush roller 53. When the brush roller 53 rotates, it can clean the sponge block 4225 and the transparent cover 33.

[0026] Combination Figures 1-12 As shown, the two sides of the upright plate 4211 are respectively attached to the inner walls of the two sides of the connecting shell 41. There is a gap 412 between the bottom of the upright plate 4211 and the inner bottom wall of the connecting shell 41. An installation port 413 is provided on the bottom of the connecting shell 41, on the side away from the vent 411 and located at the gap 412. A dust filter component 6 is installed on the connecting shell 41 and in the installation port 413. The dust filter component 6 blocks the gap 412. The dust filter component 6 is used to filter the air discharged from the vent 411. By setting the dust filter component 6, when the air flows, it drives the dust to flow into the connecting shell 41, and the dust is sucked into the interior of the connecting shell 41. The air passes through the gap 412 and is discharged through the vent 411. During this process, the dust filter component 6 filters the dust in the air, so that the dust remains in the connecting shell 41, effectively preventing the dust from being directly emitted into the ambient air, which would reduce the ambient air quality and reduce dust pollution to the environment. The dust filtering component 6 includes a collection box 61, a side blocking plate 62, a filter plate 63, and a sealing plate 64. A collection box 61 with an open top is inserted into the mounting opening 413 on the connecting shell 41. The collection box 61 is fixed to the bottom of the connecting shell 41 by screws. The top of the collection box 61 is flush with the inner bottom wall of the connecting shell 41. A side blocking plate 62, fitting against the upright plate 4211, is integrally formed on the top of the collection box 61 near the upright plate 4211, sealing the opening 412. A groove 621 communicating with the opening 412 is formed on the side blocking plate 62. A filter plate 63, sealing the groove 621, is inserted into the side blocking plate 62. A discharge port is formed at the bottom of the collection box 61. A sealing plate 64, horizontally movable and penetrating on one side of the bottom of the collection box 61, is used to seal its interior. During use, air circulation is possible. The dust is drawn into the connecting shell 41 and sucked into its interior. Air passes through the opening 412 and is then discharged through the vent 411. During this process, the filter plate 63 filters the dust in the air, and the dust adheres to the surface of the filter plate 63. Some of the dust falls into the collection box 61 under its own gravity and is collected. To clean the dust collected in the collection box 61, the operator manually pulls the sealing plate 64 to move it outward on the collection box 61, allowing the dust to be discharged through the discharge port. This facilitates the cleaning of the dust in the collection box 61. To replace the filter plate 63, the operator uses tools to remove the screws that fix the collection box 61 and pulls the filter plate 63 out of the groove 621, thus removing the filter plate 63 for replacement. The operation is simple and convenient for replacing the filter plate 63.

[0027] Combination Figures 1-12 As shown, a cleaning component 7 that acts on the filter plate 63 is installed on the upright plate 4211. The cleaning component 7 is connected to the rotating shaft 4212. When the rotating shaft 4212 rotates, the side of the filter plate 63 away from the upright plate 4211 can be cleaned through the cleaning component 7. The cleaning component 7 includes a fixed base 71 fixedly installed on the side wall of the upright plate 4211. A horizontal shaft 72 is rotatably installed on the fixed base 71. A fixed plate 73 is integrally formed on the side of the shaft 72 near the filter plate 63. A brush plate 74 in contact with the filter plate 63 is fixedly installed on the fixed plate 73. The shaft 72 and the rotating shaft 4212 are connected by a transmission component 75. In this embodiment, both the first transmission component 54 and the second transmission component 75 are belt and pulley transmission assemblies. By setting the cleaning component 7, when the rotating shaft 4212 rotates on the upright plate 4211, the second transmission component 75 drives the shaft 72 to rotate on the fixed base 71. The fixed plate 73 rotates around the shaft 72, which drives the brush plate 74 to rotate around the shaft 72. The brush plate 74 brushes the surface of the filter plate 63, achieving a cleaning effect on the surface of the filter plate 63 and effectively preventing a large amount of dust from adhering to the surface of the filter plate 63 and reducing the airflow effect.

[0028] Combination Figures 1-12 As shown, the mounting base 21 includes a hinge base 211, a hinge shaft 212, and a mounting plate 213. Both ends of the connecting arm 1 are symmetrically fixed with vertically oriented threaded posts 13. The hinge base 211 is sleeved on the outside of the two threaded posts 13 on the same side of the connecting arm 1. Nuts 14, which abut against the hinge base 211, are threaded onto the threaded posts 13. A mounting plate 213, which can fit against the bottom of the connecting arm 1, is hinged to the hinge base 211 via the hinge shaft 212. A second motor for driving the hinge shaft 212 to rotate is fixedly mounted on the hinge base 211. The housing 22 and bracket 31 are fixedly installed on the bottom of the mounting plate 213. Utilizing the special design of the mounting base 21, which includes a hinge base 211, a hinge shaft 212, and a mounting plate 213, when the ground is broken up and the broken column 11 is transferred to the next breaking point, the two motors are controlled to make the mounting plate 213 rotate around the hinge shaft 212, so that the two mounting plates 213 unfold, remove the blockage of the broken column 11, and make it easy for the operator to intuitively see the position of the broken column 11. At the same time, it prepares for the subsequent grooving cutter 83 to groove the road surface.

[0029] Combination Figures 1-12 As shown, a grooving component 8 for grooving the road surface is installed at the bottom of the lower housing 24; The grooving component 8 includes a base 81 fixedly installed at the bottom of the lower housing 24. A horizontally oriented mounting shaft 82 is rotatably mounted on the base 81. Multiple grooving blades 83, all extending below the base 81, are fixedly mounted on the outer wall of the mounting shaft 82. A motor 3 for driving the mounting shaft 82 to rotate is fixedly mounted on the base 81. By setting up the grooving component 8, when using this equipment to break up and demolish the old road surface, the operator operates the excavator and observes the position of the breaking column 11 through the display screen 35, causing the breaking column 11 to move to the designated position. The two motors 22 are controlled to rotate the mounting plates 213 around the hinge shaft 212, so that both mounting plates 213 are in contact with the bottom plate of the connecting arm 1. During the period when the two upper housings 22 and the two lower housings 24 form a cover structure, the motor 3 drives the mounting shaft 82 to rotate, driving the grooving blades 83 to rotate, thus grooving the road surface. The grooving process can create cracks in the road surface, which is beneficial for the subsequent breaking of the old road surface by the breaking column, improving the breaking efficiency and increasing the efficiency of the old road surface demolition construction.

[0030] Working principle and usage process of this invention: During installation: the connecting arm 1 is fixedly installed at the end of the excavator arm, the display screen 35 is installed in the excavator cab, and the two industrial cameras 32 capture the scene below the crushing column 11 in real time and transmit it to the display screen 35 for display. When using this equipment to break up and demolish old road surfaces, the operator operates the excavator and observes the position of the breaking column 11 through the display screen 35. The operator moves the breaking column 11 to the designated position and controls two motors to rotate the mounting plates 213 around the hinge shaft 212, ensuring that both mounting plates 213 are in contact with the bottom plate of the connecting arm 1, forming a cover structure with the two upper housings 22 and the two lower housings 24. During this process, two motors are controlled to rotate the two mounting shafts 82, driving multiple grooving cutters 83 to rotate around the mounting shafts 82. Furthermore, by controlling the excavator wall and the drive rod 23, the grooving cutters 83 are kept in contact with the ground. This allows for grooving of the road surface, which facilitates the subsequent crushing of the old road surface by the crushing column 11, creating cracks and improving crushing efficiency. When the crushing column 11 crushes the road surface, it is located inside the cover structure formed by the two upper shells 22 and the two lower shells 24. When the noise generated by the vibration between the crushing column 11 and the road surface is emitted outward through the cover structure, the noise reduction cotton board 25 inside the upper shell 22 and the lower shell 24 absorbs part of the noise before it is emitted outward, thereby reducing noise pollution and benefiting the normal activities of surrounding residents, schools, hospitals, etc. When the operator operates the excavator to move the breaking column 11 to the designated position, the two motors are turned on. Through the bevel gear assembly 4214, the rotating shaft 4212 rotates on the vertical plate 4211, which in turn drives the fan blades 4213 to rotate around the rotating shaft 4212. This draws air out of the connecting shell 41 and discharges it through the vent 411. External air flows into the inner side of the cover structure through the two upper shells 22 and the two lower shells 24. When the air flows, it carries dust into the connecting shell 41 and draws the dust into the interior of the connecting shell 41. The air passes through the notch 412 and is discharged through the vent 411. During this process, the filter plate 63 filters the dust in the air, so that the dust remains in the connecting shell 41, effectively preventing the dust from being directly emitted into the ambient air and reducing the reduction of ambient air quality, thus reducing dust pollution to the environment. After the filter plate 63 filters the dust, the dust adheres to its surface. Some of the dust falls into the collection box 61 under its own gravity. When the rotating shaft 4212 rotates on the vertical plate 4211, it drives the shaft 72 to rotate on the fixed seat 71 through the transmission component 75. The fixed plate 73 rotates around the shaft 72, which in turn drives the brush plate 74 to rotate around the shaft 72. The brush plate 74 brushes the surface of the filter plate 63, achieving a cleaning effect on the surface of the filter plate 63 and effectively preventing a large amount of dust from adhering to the surface of the filter plate 63, thus reducing dust accumulation. In cases of low airflow effect; and when the rotating shaft 4212 rotates on the vertical plate 4211, it drives the rotating rod 4221 to rotate within the connecting shell 41 via the bevel gear assembly 4222. The turntable 4226 rotates around the rotating rod 4221, and the connecting shaft 4227 performs cylindrical motion around the turntable 4226. The connecting shaft 4227 rotates with the sliding plate 4224, and the connecting shaft 4227 slides on the sliding plate 4224, causing the sliding plate 4224 to slide horizontally back and forth on the bottom plate of the connecting frame 4223, thus driving the sponge block. 4225 moves horizontally back to its original position. When the sponge block 4225 contacts the bottom of the transparent cover 33, it can wipe the bottom plate of the transparent cover 33, keeping the bottom of the transparent cover 33 clean and effectively preventing dust from adhering to the bottom of the transparent cover 33, which would affect the industrial camera 32's ability to capture images from below, thus improving the clarity of the captured image. In addition, when the rotating shaft 4212 rotates on the vertical plate 4211, it drives the two rotating shafts 52 to rotate through two sets of transmission components 54, and the two brush rollers 53 respectively wipe the transparent cover 33. The two sides rotate around two rotating shafts 52. The sliding plate 4224 slides horizontally back and forth on the bottom plate of the connecting frame 4223, which drives the sponge block 4225 to move back and forth in the horizontal direction. When the sponge block 4225 moves to the outside of the transparent cover 33, it contacts the bristles of the brush roller 53. When the brush roller 53 rotates, it can brush and clean the dust attached to the sponge block 4225 when the sponge block 4225 cleans the transparent cover 33, thereby achieving a cleaning effect on the sponge block 4225 and facilitating the subsequent cleaning of the transparent cover 33 by the sponge block 4225. By removing the seal inside the collection box 61, the dust inside can fall out through the discharge port, thus facilitating the dust collection and treatment inside the collection box 61. When replacing the filter plate 63, personnel use tools to remove the screws used to fix the collection box 61, allowing the collection box 61 to be pulled downwards from the mounting port 413. This disassembly of the collection box 61 allows the filter plate 63 to be simultaneously pulled out from the inside of the connecting shell 41. Then, force is applied to the filter plate 63 to pull it out from the groove 621, thus disassembling and replacing the filter plate 63. The operation is simple and convenient for replacing the filter plate 63. After the ground is broken up, when the broken column 11 is moved to the next breaking point, the two motors are controlled to make the mounting plates 213 rotate around the hinge shaft 212, so that the two mounting plates 213 are unfolded, the blockage of the broken column 11 is removed, and the operator can intuitively see the position of the broken column 11. At the same time, it prepares for the subsequent grooving cutter 83 to groove the road surface.
