Description

Technical Field

[0001] This invention belongs to the field of demolition robot technology, specifically relating to a highly corrosion-resistant fire-fighting demolition robot. Background Technology

[0002] In the field of modern emergency rescue, fire-fighting demolition robots, as a core component of unmanned rescue equipment, are widely used in complex and dangerous scenarios such as building collapses, chemical accidents, and maritime rescues. They undertake key tasks such as breaking down obstacles, opening rescue channels, and transferring hazardous materials. With the acceleration of urbanization and the diversification of industrial production, the environmental complexity and corrosiveness of various rescue scenarios have significantly increased: in chemical industrial park accidents, leaked acidic and alkaline chemicals and toxic and corrosive gases can easily corrode the robot's body and core components; in marine rescues or disaster response in coastal areas, high salt spray and high humidity environments can accelerate the corrosion and aging of metal components; and the high-temperature smoke and corrosive extinguishing gases remaining at fire scenes can also cause damage. Fire can also have a continuous impact on the structural integrity and operational reliability of equipment. Meanwhile, as the emergency rescue industry continues to demand higher durability and adaptability from its equipment, demolition equipment with strong environmental tolerance has become an important direction for technological development. The development of highly corrosion-resistant fire demolition robots can effectively adapt to the rescue needs of corrosive scenarios such as chemical plants, marine environments, and high-temperature fire residues. By optimizing the protective structure and material adaptation design, the damage of corrosive media to core components can be reduced, ensuring the long-term stable operation of equipment in complex environments. This provides reliable technical support for rescue operations in various challenging corrosive scenarios and promotes the development of fire rescue equipment towards multi-functionality, high tolerance, and long service life.

[0003] Existing demolition robots generate a large amount of suspended dust during operation. On the one hand, this leads to the deterioration of the rescue site environment and increases the health risk of rescuers inhaling toxic and harmful dust. Especially in confined spaces or poorly ventilated scenarios, dust accumulation may cause secondary hazards. On the other hand, the scattered dust easily adheres to the surface of the robot's core components such as transmission mechanisms, hydraulic systems, and electrical components. In conjunction with corrosive media, it exacerbates component wear and corrosion, shortens equipment maintenance cycles and service life, and may even cause key components to jam or malfunction, affecting the continuity of demolition operations and rescue efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a highly corrosion-resistant fire-fighting demolition robot.

[0005] The technical solution adopted to solve the above technical problems is: a highly corrosion-resistant fire-fighting demolition robot, including a fixed plate, a rotating disk installed on the top of the fixed plate, tracks on both sides of the fixed plate, and multiple first hydraulic rods fixedly installed on the top of the fixed plate; A mounting box is fixedly installed on the top of the rotating disk, a buckle plate is fixedly connected to the rear end of the mounting box, a transmission assembly is installed on the mounting box, and a dust collection assembly is installed on the buckle plate. The dust collection component can perform dust collection during the operation of the demolition robot, and the bottom of each of the first hydraulic rods is fixedly connected to a support plate.

[0006] Furthermore, the transmission assembly includes a mounting component fixedly connected to the mounting box. A first power arm is rotatably connected between the two sides of the mounting component. A second hydraulic rod is rotatably mounted between the rear end of the first power arm and the mounting box. A second power arm is rotatably connected between the inner sides of the upper end of the first power arm. A third hydraulic rod is rotatably mounted between the front end of the first power arm and the second power arm. A third power arm is rotatably connected to the front end of the second power arm. A fourth hydraulic rod is rotatably mounted between the bottom of the second power arm and the third power arm. A first connecting rod and a second connecting rod are fixedly connected to the front ends of both sides of the third power arm. An arc-shaped plate is rotatably connected to the outer surface of each of the two first connecting rods. A mounting base is rotatably mounted between the two second connecting rods. A linkage plate is rotatably connected between the two arc-shaped plates and the mounting base. A fifth hydraulic rod is rotatably mounted between the two arc-shaped plates and the third power arm. A demolition drill bit is fixedly connected to the bottom of the mounting base.

[0007] Through the above technical solution, firstly, the second hydraulic rod extends and retracts, driving the first power arm to rotate around the mounting component, thus extending the first power arm from its retracted state to the working angle. Then, the third hydraulic rod extends and retracts, causing the second power arm to rotate around the inner side of the upper end of the first power arm, adjusting the working posture of the second power arm. Next, the fourth hydraulic rod extends and retracts, pushing the third power arm to rotate around the front end of the second power arm, adjusting the demolition drill bit to a position close to the working surface. Finally, the fifth hydraulic rod extends and retracts, causing the arc plate to rotate around the first connecting rod. The arc plate pulls the mounting base to rotate around the second connecting rod through the linkage plate, ultimately adjusting the working angle of the demolition drill bit. At this time, the demolition drill bit starts, coordinating with the posture maintenance of each power arm to perform demolition operations on the working surface. After the operation is completed, each hydraulic rod moves in reverse, sequentially driving the third power arm, the second power arm, and the first power arm to retract, so that the transmission components return to the initial state.

[0008] Furthermore, both of the arc-shaped plates are rotatably sleeved on the outer surface of the corresponding first connecting rod, and the fifth hydraulic rod is rotatably connected between the two arc-shaped plates and the third power arm.

[0009] The above technical solution can achieve precise and flexible multi-angle micro-adjustment of the demolition drill bit through symmetrical layout and rotational coordination, and can also form a stable triangular force structure to disperse concentrated stress during operation, reduce component friction resistance, balance the overall force to improve the structure's resistance to deformation and vibration, and can also offset the demolition impact force by reserving buffer space through rotational connection, effectively protecting key components and adapting to complex demolition scenarios.

[0010] Furthermore, the upper inner side of the mounting base is rotatably connected to two second connecting rods, and the mounting base can rotate around the axes of the two second connecting rods.

[0011] The above technical solution can provide stable rotational support for the mounting base and the demolition drill bit, ensuring coaxiality and stability during angle adjustment. It can also work with the transmission of the arc plate and the linkage plate to achieve flexible angle adaptation of the demolition drill bit. At the same time, the dual-point rotational connection can disperse the impact force during demolition operations, reduce the single-point load, and improve the structural stability and service life of the mounting base.

[0012] Furthermore, both the first connecting rod and the second connecting rod are fixed to the front ends of both sides of the third power arm, and the first connecting rod and the second connecting rod are distributed along the length direction of the third power arm.

[0013] The above technical solution can provide staggered installation support points for the arc plate and mounting base, forming a reasonable force transmission path. It can also achieve precise angle adjustment of the demolition drill bit in conjunction with the linkage structure. Furthermore, it can make the layout of each component compact and the force balanced, avoiding spatial interference. At the same time, it can disperse the concentrated load during demolition operations, improve the structural bearing capacity and overall transmission stability of the front end of the third power arm.

[0014] Furthermore, the vacuuming assembly includes a vacuum box slidably mounted on a buckle plate, a rotatable door mounted on the vacuum box, two first threaded tubes fixedly connected to the top of the vacuum box, a buckle groove provided at the front end of the vacuum box, a mounting box fixedly connected to the rear end of the vacuum box, a mesh screen fixedly installed inside the vacuum box, a motor mounted on one side of the outer wall of the mounting box, a rotating rod fixedly connected to the output end of the motor, a rotating wheel fixedly installed on the outer surface of the rotating rod, multiple heat dissipation slots opened at the rear end of the mounting box, limit plates fixedly connected to both sides of the second power arm, first threaded tubes fixedly connected to both ends of the two limit plates, first threaded tubes fixedly connected to both sides of the upper surface of the mounting base, and multiple... Each of the first threaded tubes has a second threaded tube threaded to its outer wall. Each of the second threaded tubes has an anti-detachment groove on its inner side. Each of the anti-detachment grooves has a retaining ring rotatably installed inside. A suction pipe is fixedly connected between every two retaining rings. Each suction pipe passes through a corresponding support ring and support plate. Two mounting tubes are fixedly connected to the bottom of the mounting base. Each of the two mounting tubes has two guide grooves at its bottom. Guide rods are fixedly connected inside each of the guide grooves. Springs are slidably connected to the outer surface of each guide rod. A protective disc is slidably installed between every two guide rods. A fixing ring is installed at the bottom of each of the two mounting tubes. Multiple bolts are threadedly connected between each fixing ring and its corresponding mounting tube.

[0015] With the above technical solution, when the demolition robot starts the demolition operation, the motor on the outer wall of the mounting box is started simultaneously. The motor output drives the rotating rod and the rotating wheel on the outer surface to rotate, generating negative pressure suction. The dust generated during the demolition process is sucked into the suction pipe through the periphery of the bottom of the mounting base, and then transferred to the dust collection box. The screen intercepts and filters the dust. The heat generated by the motor is dissipated through the heat dissipation slots at the rear of the mounting box. During the operation, the protective plate slides along the guide rod with the vibration of the demolition surface, and the spring buffers the impact force to prevent dust from escaping from the gap between the mounting pipe and the working surface. The suction pipe adapts to the posture adjustment of the power arm through the rotation of the buckle ring to ensure that the suction path is always smooth. After the demolition operation is completed, the motor is turned off, the buckle slot is released, and the dust collection box is slid out from the buckle plate. Then the switch door is opened, the dust intercepted in the dust collection box and the attached objects on the screen surface are cleaned, and after checking that there is no damage to the suction pipes, threaded pipe connections and protective structures, the dust collection components are reset and installed, ready for the next operation.

[0016] Furthermore, the buckle plate has sliding grooves on both sides, and the buckle groove at the front end of the dust collection box matches the sliding groove.

[0017] The above technical solution can provide precise sliding guidance for the vacuum cleaner box, ensuring smooth and stable installation and disassembly, avoiding deviation and jamming. It can also enhance the installation stability of the vacuum cleaner box during operation through the fitting and limiting of the sliding groove and the buckle groove, preventing the vacuum cleaner box from shifting due to vibration during disassembly. At the same time, it simplifies the assembly operation, and the positioning and fixing of the vacuum cleaner box can be completed quickly without complex fixing structures.

[0018] Furthermore, multiple fan blades are fixedly connected to the outer surface of the rotating wheel, and the multiple fan blades are evenly distributed along the circumference of the rotating wheel.

[0019] The above technical solution can form a stable and balanced negative pressure suction under the drive of the motor, ensuring the efficient adsorption and transmission of dust by the suction pipe, avoiding dust dispersion caused by uneven suction, and balancing the force when the fan blades rotate, reducing vibration and noise, reducing the operating load of the motor, while the evenly distributed fan blades can improve the airflow circulation efficiency.

[0020] Furthermore, both of the protective discs have sliding holes at their bottoms, and the multiple guide rods are matched with the corresponding sliding holes.

[0021] The above technical solution can provide precise sliding guidance for the protective disc, ensuring its smooth lifting and lowering along the guide rod axis and avoiding deviation and jamming. It can also limit the lateral displacement of the protective disc through the fit between the sliding hole and the guide rod, enhancing its structural stability in the vibration environment of demolition. At the same time, it can make the extension and contraction force of the spring more concentrated, improving the buffering and vibration reduction effect.

[0022] Furthermore, the outer surfaces of the multiple buckle rings are tightly fitted with the corresponding anti-detachment grooves.

[0023] The above technical solution can prevent the buckle ring from falling out of the second threaded tube by fitting and limiting, ensuring the reliability of the vacuum tube connection. It can also reduce the radial sway of the buckle ring without affecting its rotation function, ensuring smooth force transmission of the vacuum tube when the power arm posture is adjusted. At the same time, it can prevent dust from seeping in from the mating gap and causing the parts to jam, thus improving the sealing performance and long-term operational stability of the vacuum assembly.

[0024] The beneficial effects of the present invention are as follows: (1) By setting up a dust suction component, the present invention can adsorb the suspended dust generated during the demolition operation in real time, effectively reducing the dispersion and accumulation of dust in the rescue environment, improving the air quality at the scene from the source, and significantly reducing the health risk of rescuers inhaling toxic and harmful dust and corrosive dust in enclosed spaces, poorly ventilated underground passages or chemical accident sites. At the same time, it can also prevent dust from adhering to the core components such as the robot's transmission mechanism, hydraulic system, electrical components, and precision control interface, greatly improving the service life of the demolition robot; (2) The present invention uses a guide rod, spring and protective disc. The spring absorbs the vibration impact force and the contact stress of the working surface through the extension and deformation, avoiding rigid collisions that could damage the components around the installation pipe. At the same time, the buffering effect can reduce the loosening of components caused by vibration, prevent dust and corrosive media from seeping in due to increased gaps, and further enhance the structural stability of the equipment in complex vibration scenarios.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] like Figure 1 - Figure 12As shown, this embodiment of a highly corrosion-resistant fire-fighting demolition robot includes a fixed plate 1, a rotating disk 2 mounted on the top of the fixed plate 1, tracks 3 on both sides of the fixed plate 1, a plurality of first hydraulic rods 4 fixedly mounted on the top of the fixed plate 1, a mounting box 5 fixedly mounted on the top of the rotating disk 2, a buckle plate 6 fixedly connected to the rear end of the mounting box 5, a transmission assembly 7 mounted on the mounting box 5, the transmission assembly 7 including a mounting component 701 fixedly connected to the mounting box 5, a first power arm 702 rotatably connected between the two sides of the mounting component 701, a second hydraulic rod 703 rotatably mounted between the rear end of the first power arm 702 and the mounting box 5, and a second power arm 704 rotatably connected between the inner sides of the upper ends of the first power arm 702. A third hydraulic rod 705 is rotatably mounted between the front end of a first power arm 702 and a second power arm 704. A third power arm 706 is rotatably connected to the front end of the second power arm 704. A fourth hydraulic rod 707 is rotatably mounted between the bottom of the second power arm 704 and the third power arm 706. First connecting rods 708 and second connecting rods 709 are fixedly connected to the front ends of both sides of the third power arm 706. Arc-shaped plates 7010 are rotatably connected to the outer surfaces of the two first connecting rods 708. A mounting base 7011 is rotatably mounted between the two second connecting rods 709. A linkage plate 7012 is rotatably connected between the two arc-shaped plates 7010 and the mounting base 7011. A linkage plate 7012 is rotatably connected between the two arc-shaped plates 7010 and the third power arm 706. A fifth hydraulic rod 7013 is mounted on the mounting base 7011, and a demolition drill bit 7014 is fixedly connected to the bottom of the mounting base 7011. First, the second hydraulic rod 703 extends and retracts, driving the first power arm 702 to rotate around the mounting component 701, thus extending the first power arm 702 from its retracted state to the working angle. Then, the third hydraulic rod 705 extends and retracts, causing the second power arm 704 to rotate around the inner side of the upper end of the first power arm 702, adjusting the working posture of the second power arm 704. Next, the fourth hydraulic rod 707 extends and retracts, pushing the third power arm 706 to rotate around the front end of the second power arm 704, adjusting the demolition drill bit 7014 to a position close to the working surface. Finally, the fifth hydraulic rod 7013 extends and retracts, driving the arc plate 70... 10 rotates around the first connecting rod 708, and the arc plate 7010 pulls the mounting base 7011 around the second connecting rod 709 through the linkage plate 7012, finally adjusting the working angle of the demolition drill bit 7014. At this time, the demolition drill bit 7014 starts, and in coordination with the posture of each power arm, it performs demolition operation on the working surface. After the operation is completed, each hydraulic rod moves in the opposite direction, sequentially driving the third power arm 706, the second power arm 704, and the first power arm 702 to retract, so that the transmission component 7 returns to the initial state. Both arc plates 7010 are rotated and sleeved on the outer surface of the corresponding first connecting rod 708, and the fifth hydraulic rod 7013 is rotatably connected between the two arc plates 7010 and the third power arm 706.The symmetrical layout and rotating mechanism enable precise and flexible multi-angle micro-adjustment of the demolition drill bit 7014. It also forms a stable triangular force-bearing structure, dispersing concentrated stress during operation, reducing component friction resistance, and balancing overall force to enhance structural resistance to deformation and vibration. Furthermore, the rotating connection provides a buffer space to offset demolition impact, effectively protecting critical components and adapting to complex demolition scenarios. Two second connecting rods 709 are rotatably connected to the upper inner side of the mounting base 7011, and the mounting base 7011 can rotate around the axes of the two second connecting rods 709. This provides stable rotational support for the mounting base 7011 and the demolition drill bit 7014, ensuring coaxiality and stability during angle adjustment. It also works in conjunction with the transmission of the arc plate 7010 and the linkage plate 7012 to achieve the desired demolition drill bit... The flexible angle adaptation of the 7014, along with the dual-point rotation connection, disperses the impact force during demolition operations, reduces single-point load, and improves the structural stability and service life of the mounting base 7011. The first connecting rod 708 and the second connecting rod 709 are both fixed to the front ends of both sides of the third power arm 706, and are distributed along the length of the third power arm 706. This provides staggered mounting points for the arc plate 7010 and the mounting base 7011, forming a reasonable force transmission path. Combined with the linkage structure, this allows for precise angle adjustment of the demolition drill bit 7014. It also ensures a compact layout and balanced force distribution among components, avoiding spatial interference, while dispersing concentrated loads during demolition operations, thus improving the structural load-bearing capacity and overall transmission stability of the front end of the third power arm 706.

[0029] like Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 10 , Figure 11 and Figure 12As shown, a dust collection component 8 is installed on the buckle plate 6. The dust collection component 8 can perform dust collection during the operation of the demolition robot. Multiple first hydraulic rods 4 are fixedly connected to support plates 9 at their bottoms. The dust collection component 8 includes a dust collection box 801 slidably mounted on the buckle plate 6. A switch door 802 is rotatably mounted on the dust collection box 801. Two first threaded tubes 803 are fixedly connected to the top of the dust collection box 801. A buckle groove 804 is provided at the front end of the dust collection box 801. A mounting box 805 is fixedly connected to the rear end of the dust collection box 801. A mesh screen 806 is fixedly installed inside the dust collection box 801. A motor 807 is installed on one side of the outer wall of the mounting box 805. A rotating rod 808 is fixedly connected to the output end of the motor 807. A rotating wheel 809 is fixedly installed on the outer surface of the rotating rod 808. Multiple heat dissipation slots 8010 are provided at the rear end of the mounting box 805. Limiting plates 8021 are fixedly connected to both sides of the second power arm 704. First threaded tubes 803 are fixedly connected to both ends of the two limiting plates 8021. First threaded tubes 803 are fixedly connected to both sides of the upper surface of the mounting base 7011. Second threaded tubes 8011 are threadedly connected to the outer walls of multiple first threaded tubes 803. Anti-detachment grooves 8014 are provided on the inner sides of multiple second threaded tubes 8011. Clamping rings 8013 are rotatably installed inside each anti-detachment groove 8014. A suction pipe 8012 is fixedly connected between every two clamping rings 8013. Each suction pipe 8012 passes through the corresponding support ring 8024 and support plate 8022. Two mounting pipes 8023 are fixedly connected to the bottom of the mounting base 7011. Each mounting pipe 8023 has two guide grooves 8015 at its bottom. Guide rods 8016 are fixedly connected inside each guide groove 8015. Springs 8017 are slidably connected to the outer surface of each guide rod 8016. A protective disc 8018 is slidably installed between every two guide rods 8016. A fixing ring 8019 is installed at the bottom of each mounting pipe 8023. Multiple bolts 8020 are threadedly connected between each fixing ring 8019 and the corresponding mounting pipe 8023. When the demolition robot starts its demolition operation... The motor 807 on the outer wall of the mounting box 805 is started synchronously. The output end of the motor 807 drives the rotating rod 808 and the rotating wheel 809 on the outer surface to rotate, generating negative pressure suction. The dust generated during the demolition process is sucked into the suction pipe 8012 through the bottom periphery of the mounting base 7011 and then transferred to the dust collection box 801. The mesh 806 intercepts and filters the dust. The heat generated by the motor 807 is dissipated through the heat dissipation slot 8010 at the rear end of the mounting box 805. During the operation, the protective plate 8018 slides through the guide rod 8016 with the vibration of the demolition surface, and the spring 8017 buffers the impact force to prevent dust from escaping from the gap between the mounting tube 8023 and the working surface.The suction pipe 8012 adapts to the posture adjustment of the power arm through the rotation of the buckle ring 8013, ensuring that the suction path is always smooth. After the dismantling operation is completed, the motor 807 is turned off, the buckle slot 804 is released, and the suction box 801 is slid out from the buckle plate 6. Then, the switch door 802 is opened, and the dust trapped in the suction box 801 and the attachments on the surface of the mesh 806 are cleaned. After checking that there is no damage to the suction pipes 8012, threaded pipe connections, and protective structures, the suction assembly 8 is reset and installed, ready for the next operation. The buckle plate 6 has sliding grooves on both sides, and the buckle slot 804 at the front of the suction box 801 matches the sliding grooves; It provides precise sliding guidance for the vacuum cleaner 801, ensuring smooth and stable installation and disassembly, avoiding displacement and jamming. The fitting and limiting of the sliding groove and the snap-fit ​​groove 804 enhances the installation stability of the vacuum cleaner 801 during operation, preventing displacement due to vibration during disassembly. It also simplifies assembly, allowing for quick positioning and fixation of the vacuum cleaner 801 without complex fixing structures. Multiple fan blades are fixedly connected to the outer surface of the rotating wheel 809, and these blades are evenly distributed circumferentially along the rotating wheel 809. Driven by the motor 807, this creates a stable and balanced negative pressure suction, ensuring that the suction pipe 8012 effectively removes dust from the vacuum cleaner. The efficient adsorption and transport of dust prevents dust dispersion caused by uneven suction, and ensures balanced force during fan blade rotation, reducing vibration and noise and lowering the operating load on the motor 807. The evenly distributed fan blades also improve airflow circulation efficiency. Both protective discs 8018 have sliding holes at their bottoms, and multiple guide rods 8016 match the corresponding sliding holes. This provides precise sliding guidance for the protective discs 8018, ensuring smooth lifting and lowering along the axis of the guide rods 8016 and preventing deviation or jamming. Furthermore, the close fit between the sliding holes and the guide rods 8016 limits the lateral displacement of the protective discs 8018, enhancing their performance in vibration-prone environments. This design improves structural stability and concentrates the extension and retraction force of the spring 8017, enhancing the cushioning and vibration reduction effect. Multiple locking rings 8013 have their outer surfaces tightly fitted with corresponding anti-detachment grooves 8014. This fit prevents the locking rings 8013 from detaching from the second threaded tube 8011, ensuring the reliability of the suction pipe 8012 connection. It also reduces radial sway without affecting the rotation function of the locking rings 8013, ensuring smooth force transmission to the suction pipe 8012 during power arm posture adjustment. Furthermore, it prevents dust from seeping into the fitting gaps and causing component jamming, thus improving the sealing performance and long-term operational stability of the suction assembly 8.

[0030] The working principle of this embodiment is as follows: First, the second hydraulic rod 703 extends and retracts, driving the first power arm 702 to rotate around the mounting component 701, causing the first power arm 702 to extend from the retracted state to the working angle. Then, the third hydraulic rod 705 extends and retracts, driving the second power arm 704 to rotate around the inner side of the upper end of the first power arm 702, adjusting the working posture of the second power arm 704. Then, the fourth hydraulic rod 707 extends and retracts, pushing the third power arm 706 to rotate around the front end of the second power arm 704, adjusting the demolition drill bit 7014 to a position close to the working surface. Finally, the fifth hydraulic rod 7013 extends and retracts, driving the arc plate 7010 to rotate around the first connecting rod 708. The arc plate 7010 pulls the mounting base 7011 to rotate around the second connecting rod 709 through the linkage plate 7012, finally adjusting the working angle of the demolition drill bit 7014. At this time, the demolition drill bit 7014 starts, coordinating with the posture maintenance of each power arm to perform demolition operations on the working surface. The demolition robot starts demolition. During disassembly, the motor 807 on the outer wall of the mounting box 805 is started simultaneously. The output of the motor 807 drives the rotating rod 808 and the rotating wheel 809 on the outer surface to rotate, generating negative pressure suction. The dust generated during the disassembly process is sucked into the suction pipe 8012 through the bottom periphery of the mounting pipe 8023, and then transferred to the dust collection box 801 through the suction pipe 8012. The mesh 806 intercepts the dust, and the heat generated by the motor 807 is dissipated through the heat dissipation slot 8010 at the rear of the mounting box 805. During the operation, the protective disc 8018 slides along the guide rod 8016 as the demolition surface vibrates, the spring 8017 buffers the impact force, and the suction pipe 8012 adapts to the outer wall of the corresponding first threaded pipe 803 through the rotation of the buckle ring 8013, thereby ensuring that the suction path is always smooth. After the demolition operation is completed, the motor 807 is turned off, and then the switch door 802 is opened to clean the dust in the dust collection box 801 and check each suction pipe 8012, threaded pipe connection and protective structure.

[0031] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
