Description

Technical Field

[0001] This invention relates to the field of long-distance surface dust negative pressure cleaning technology, and more particularly to a long-distance surface dust negative pressure cleaning device. Background Technology

[0002] The cement production area inevitably generates dust due to the production processes such as raw material crushing and transportation, cement grinding and transportation. Even with fully enclosed equipment, dust leakage is unavoidable. In particular, belt conveyor corridors, transfer stations, and silo storage and unloading points for raw materials are not only key dust generators, but also areas where equipment and facilities are located, resulting in problems such as uneven structures, long corridor distances, and multiple layers of space in transfer stations.

[0003] Chinese patent CN119405202A discloses a long-distance surface dust negative pressure cleaning device, including a dust removal subsystem and a centralized dust bin. The number of dust removal subsystems is multiple and they are arranged in parallel. Each dust removal subsystem includes a dust collection component and a dust conveying component.

[0004] However, when dust escapes from the factory production process and is distributed on the ground, it tends to accumulate on the inside of the machine's bottom support and in the corners. At the same time, the accumulated dust will also become damp and combined. During regular cleaning, it is necessary to manually break up the scattered dust and frequently change the end of the cleaning rake to adapt to different locations. The process is tedious and time-consuming. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a long-distance surface dust negative pressure cleaning device. By setting up a cleaning mechanism, it enables rapid adjustment of corner positions during the cleaning process and improves the cleaning effect. It solves the technical problem that dust easily accumulates and combines in the inner side and corners of the machine's bottom support, making manual cleaning cumbersome and labor-intensive.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a long-distance surface dust negative pressure cleaning device, comprising a vacuum cleaner main unit and a main pipe connected to the vacuum cleaner main unit and having multiple sets of connection ends, and further comprising: The cleaning mechanism is engaged with the connecting end and includes a rake head assembly connected to the connecting end, a directional component disposed on the rake head assembly, a disturbance component disposed on both sides of the rake head assembly, a side suction component disposed at both ends of the rake head assembly, a piercing component disposed on the side suction component, and a stirring component disposed on the side suction component. When the cleaning work begins, the worker connects the rake head assembly to the connection end on the main pipe. The negative pressure of the vacuum cleaner drives the surface dust to be collected. When cleaning the space at the bottom of the equipment, the worker changes the working state of the rake head assembly from horizontal to vertical movement by squeezing it against the side wall and adjusting the directional component. At the same time, the agitation component moves the dust accumulated at the side edge. When it reaches the corner, the side suction component squeezes against the corner while the piercing component and the agitation component work together to disperse and collect the stubborn dust in the corner.

[0007] Furthermore, the rake head assembly includes a dust collection box with two sets of collection ports at the bottom, a cover plate connected to the dust collection box, a connecting pipe passing through the cover plate and connected to the cover plate by a torsion spring, and two sets of rollers connected to both ends of the dust collection box by a rotating shaft.

[0008] Furthermore, the steering assembly includes a first half gear connected to the connecting pipe, two sets of first drive racks respectively connected to the cover plate by a first telescopic member and meshing with the first half gear, a first rack connected to the end of the first drive rack by a second telescopic member, and a first gear connected to the rotating shaft and meshing with the first rack.

[0009] Furthermore, the disturbance component includes mounting slots on both sides of the dust collection box, multiple sets of fixing rings connected in the mounting slots, positioning wheels connected to the fixing rings, trigger rods connected to the inner side of the positioning wheels, multiple sets of inner rods connected in the mounting slots and corresponding to the fixing rings, sleeve rods sleeved on the inner rods and connected to the mounting slots via a first spring, a spiral guide rail connected to the sleeve rods and cooperating with the trigger rods to drive the sleeve rods to move, and a disturbance seat connected to the bottom of the sleeve rods.

[0010] Furthermore, the side suction assembly includes a side suction frame that runs through the dust collection box and is connected to the dust collection box via a third telescopic member, as well as two sets of guide ports that are opened on the side suction frame and are used to cooperate with the connecting pipe to change the collection direction.

[0011] Furthermore, the piercing assembly includes multiple sets of piercing rods that pass through both ends of the side suction frame and are connected to the top via a receiving member, multiple sets of second springs that are sleeved on the piercing rods and located between the receiving member and the side suction frame, and a trapezoidal block that is connected to the dust collection box via a fourth telescopic member and is used to drive the receiving member to move downward.

[0012] Furthermore, the agitation assembly includes a first bracket and a second bracket connected to the inner and outer sides of the side suction frame respectively, a transmission ring and a transmission shaft connected to the first bracket and the second bracket respectively, a belt drive component connected to the transmission ring and the transmission shaft at both ends and passing through the side suction frame, a second gear connected to the transmission shaft, a second rack connected to the dust collection box and meshing with the second gear, a sprocket and chain drive component connected to multiple sets of piercing rods, and an agitation claw connected to the end of the piercing rod.

[0013] Furthermore, the long-distance surface dust negative pressure cleaning device also includes: A connecting mechanism, wherein the connecting mechanism is disposed on the main pipeline and includes a sealing component connected to the main pipeline and a detection component disposed on the main pipeline; Before the rake head assembly is connected to the connecting end, the detection component checks the blockage inside the main pipe. Then, when the rake head assembly engages with the corresponding connecting end, the sealing component cuts off the internal space of the main pipe at the corresponding position.

[0014] Furthermore, the sealing assembly includes multiple sets of first sealing plates connected inside the main pipe and corresponding to the connection ends, a storage groove opened in the first sealing plate, a shaft rod that passes through the main pipe and the first sealing plate in sequence and has a follower gear connected to its top, a second sealing plate connected to one end of the shaft rod and located in the storage groove, a third spring sleeved on the shaft rod and located between the main pipe and the follower gear, a locking frame connected to the main pipe and located outside the connection end, an annular cap connected to one end of the connecting pipe, a second half gear connected to the connecting pipe and meshing with the follower gear, and a locking block connected to the connecting pipe and cooperating with the locking frame to fix the connecting pipe.

[0015] Furthermore, the detection component includes two sets of fixed pulleys connected to the main pipe, a drive wheel connected to the motor output end, a transmission rope passing through the main pipe and wound around the fixed pulleys and drive wheel, and multiple sets of cleaning blocks connected to the transmission rope and located inside the main pipe.

[0016] The beneficial effects of this invention are as follows: (1) By setting up a cleaning mechanism that works with the main pipeline, the present invention not only achieves large-area coverage cleaning of the factory, but also achieves precise and efficient cleaning of complex dead corners through the linkage design of unique directional components, disturbance components, side suction components, piercing components and stirring components. It is particularly good at mechanically piercing and dispersing the hardened dust in the corners and side walls, thus solving the technical problem that traditional methods are difficult to thoroughly clean the accumulated materials in the corners, and workers need to frequently change tools or make complex adjustments, which is cumbersome.

[0017] (2) By setting up a blocking component, the present invention dynamically optimizes the negative pressure of the system and improves the cleaning efficiency under long pipes. Through the blocking component in the connecting mechanism, the remote pipe can be automatically cut off at the moment the cleaning mechanism is connected to the main pipe, effectively shortening the actual working pipe length, greatly reducing the loss of negative pressure of the blower due to pipe friction, and ensuring that the cleaning end always has sufficient suction.

[0018] (3) By setting up a detection component, the present invention enables the system to have pipeline self-inspection and anti-blocking functions, ensuring the reliability of system operation. Before each cleaning operation, the detection component can automatically inspect the internal condition of the main pipeline, and use the movement of the cleaning block to judge and initially clear the blockage point. This preventive measure ensures that the air path is unobstructed, avoids the interruption of operation due to sudden pipeline blockage, and also ensures that the sealing component can work normally, improving the stability and maintainability of the entire system.

[0019] In summary, the present invention has the advantages of strong adaptability and thorough cleaning. Attached Figure Description

Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] Example 1 like Figures 1 to 10 As shown, this embodiment provides a long-distance surface dust negative pressure cleaning device, including a vacuum cleaner host 100 and a main pipe 300 connected to the vacuum cleaner host 100 and having multiple sets of connection ends 200, and also includes: The cleaning mechanism 1 is engaged with the connecting end 200 and includes a rake head assembly 11 connected to the connecting end 200, a directional component 12 disposed on the rake head assembly 11, a disturbance component 13 disposed on both sides of the rake head assembly 11, a side suction component 14 disposed at both ends of the rake head assembly 11, a piercing component 15 disposed on the side suction component 14, and a stirring component 16 disposed on the side suction component 14. When the cleaning work begins, the worker connects the rake head assembly 11 to the connection end 200 on the main pipe 300. The negative pressure of the vacuum cleaner 100 drives the surface dust to be collected. When cleaning the space at the bottom of the equipment, the worker changes the working state of the rake head assembly 11 from horizontal to vertical movement by squeezing and adjusting the directional assembly 12 with the side wall. At the same time, the agitation assembly 13 drives the dust gathered at the side edge to be stirred. When it reaches the corner, the side suction assembly 14 squeezes the corner with the corner while the piercing assembly 15 and the stirring assembly 16 are used to disperse and collect the stubborn dust in the corner.

[0024] In this embodiment, by setting up the cleaning mechanism 1, the cleaning effect can be quickly adjusted for the corners during the cleaning process, thus solving the technical problem that dust easily accumulates and combines in the inner side and corners of the machine's bottom support, making manual cleaning tedious and labor-intensive. In addition, the self-made vacuum cleaner host 100 includes: a high-pressure energy-saving fan, 16 filter bags and cages, 5 pulse valves, 1 pneumatic ash discharge butterfly valve, etc., and a modified electrical cabinet is used to control the dust removal system. The main pipe 300 is laid along the transfer station or corridor wall with φ75 plastic pipes as a centralized dust collection pipe. A quick interface 200 is opened every 6m on it to connect the rake head assembly 11. By forming a main unit + pipe layout, the entire area to be cleaned can be covered. The vacuum main unit 100 is turned on and connected to the cleaning mechanism 1 to perform negative pressure cleaning. After cleaning one location, the connection 200 is closed and the cleaning mechanism 1 is connected to another connection 200 to clean another location. This setting makes cleaning stairs, belt conveyor heads, tails and bottom spaces very simple, and the cleaning efficiency is high with no secondary dust. Its features are multi-functionality: it can be used for floor cleaning, as well as vertical surfaces such as walls, belt corridor walls, machine frame protective covers, inclined surfaces and stair treads.

[0025] Furthermore, such as Figures 1 to 3 As shown, the rake head assembly 11 includes a dust collection box 111 with two sets of collection ports 110 at the bottom, a cover plate 112 connected to the dust collection box 111, a connecting pipe 114 passing through the cover plate 112 and connected to the cover plate 112 by a torsion spring 113, and two sets of rollers 116 connected to both ends of the dust collection box 111 by a rotating shaft 115.

[0026] In this embodiment, by setting collection ports 110 on both sides of the dust collection box 111, it can get closer to the dust position when it is near the wall, thereby improving collection efficiency and effect. In addition, the torsion spring 113 keeps the dust collection box 111 and the connecting pipe 114 in a vertical state, which facilitates operation during work.

[0027] In detail, after the connecting pipe 114 engages with the connecting end 200 on the main pipe 300, the vacuum cleaner host 100 is started, and the worker pushes the dust collection box 111 to move through the connecting pipe 114 to collect dust on the ground.

[0028] It should be noted that the connecting pipe 114 includes a cleaning hose of approximately 3-4 meters to accommodate various operations.

[0029] Furthermore, such as Figures 2 to 6 As shown, the steering assembly 12 includes a first half gear 121 connected to the connecting pipe 114, two sets of first drive racks 123 respectively connected to the cover plate 112 via first telescopic members 122 and meshing with the first half gear 121, a first rack 125 connected to the end of the first drive rack 123 via a second telescopic member 124, and a first gear 126 connected to the rotating shaft 115 and meshing with the first rack 125.

[0030] In this embodiment, the direction of the roller 116 is controlled by the directional component 12, which makes it easier for workers to push the dust collection box 111 along the wall when cleaning the wall. Furthermore, by setting the transmission differences between the first drive rack 123 and the first half gear 121, and between the first rack 125 and the first gear 126, the first rack 125 and the first gear 126 can complete the 90° rotation transmission of the roller 116 in the initial stage of the meshing transmission between the first drive rack 123 and the first half gear 121. Thus, during the cleaning process, the worker can arbitrarily change the angle between the connecting pipe 114 and the dust collection box 111 by pressing against the wall, and at the same time immediately change the orientation of the roller 116, which facilitates the cleaning work.

[0031] In detail, when cleaning an open area, because there is a certain driving distance between the first drive rack 123 and the first half gear 121, that is, when the dust collection box 111 vibrates during the cleaning process, causing a slight change in the angle between it and the connecting pipe 114, it will not drive the adjusting component 12 to work, and the roller 116 will always remain in its current state. When the worker needs to clean the bottom support of the machine, the dust located by the wall needs to be pushed by the worker through the connecting pipe 114 so that its side is in contact with the wall. Then, the worker rotates the connecting pipe 114, and the first half gear 121 located on the connecting pipe 114 begins to rotate. When the first half gear 121 meshes with the first drive rack 123, the first drive rack 123 drives the first rack 125 to move through the second telescopic member 124, and the first rack 125 moves. Under the meshing of the first gear 126 and the first gear 125, the rotating shaft 115 drives the roller 116 to quickly complete a 90° rotation. The first rack 125 and the first gear 126 also disengage. Then, when the worker continues to reduce the angle between the connecting pipe 114 and the wall on the same side, the first rack 125 stops moving when it comes into contact with the edge of the dust collection box 111. The second telescopic member 124 retracts to compensate. Similarly, when cleaning the other side of the wall, the first telescopic member 122 retracts to compensate for the distance that the connecting pipe 114 drives the first drive rack 123 to move. When the roller 116 is parallel to the wall, the worker pushes the connecting pipe 114 to make the dust collection box 111 move along the wall to collect dust. After collection, the connecting pipe 114 resets. Under the drive of the first telescopic member 122 and the second telescopic member 124, the adjusting component 12 and the roller 116 also reset.

[0032] It should be noted that a damper is provided at the connection between the rotating shaft 115 on the roller 116 and the dust collection box 111 to improve the stability of the roller 116 and prevent it from changing its orientation during vibration. In addition, the meshing of the first rack 125 and the first gear 126 also plays a certain locking role.

[0033] Furthermore, such as Figures 2 to 7As shown, the disturbance component 13 includes mounting slots 130 on both sides of the dust collection box 111, multiple sets of fixing rings 131 connected in the mounting slots 130, positioning wheels 132 connected to the fixing rings 131, trigger rods 133 connected to the inner side of the positioning wheels 132, multiple sets of inner rods 134 connected in the mounting slots 130 and corresponding to the fixing rings 131, sleeve rods 136 sleeved on the inner rods 134 and connected to the mounting slots 130 through a first spring 135, a spiral guide rail 137 connected to the sleeve rods 136 and cooperating with the trigger rods 133 to drive the sleeve rods 136 to move, and a disturbance seat 138 connected to the bottom of the sleeve rods 136.

[0034] In this embodiment, by setting the disturbance component 13, the disturbance component 13 can be quickly extended to disturb the dust accumulated on the wall side when cleaning along the wall, so that it is dispersed and made easier for the dust collection box 111 to collect, thereby improving the cleaning effect. The presence of the positioning wheel 132 also reduces the friction between the dust collection box 111 and the wall surface, protecting the integrity of the surface of the dust collection box 111.

[0035] In detail, when the dust collection box 111 is pushed forward along the wall, the positioning wheel 132 on one side starts to rotate due to friction with the wall. When it rotates, the trigger rod 133 connected to its inner wall also rotates and squeezes the spiral guide rail 137. Finally, under the pressure of the trigger rod 133, the spiral guide rail 137 drives the sleeve rod 136 to move downward along the inner rod 134. This also causes the disturbance seat 138 connected to the lower end of the sleeve rod 136 to extend downward. As the movement progresses, the disturbance effect on the dust on the wall side is achieved through the end. At the end, the positioning wheel 132 is rotated in the opposite direction due to friction, and the disturbance component 13 is reset under the action of the first spring 135.

[0036] It should be noted that the surface of the positioning wheel 132 is made of rubber to improve the friction effect, and the bottom of the disturbance seat 138 is set in a serrated shape to improve its effect on breaking up agglomerated dust; both ends of the first spring 135 are free ends.

[0037] Furthermore, such as Figures 2 to 3 and Figure 8 As shown, the side suction assembly 14 includes a side suction frame 142 that runs through the dust collection box 111 and is connected to the dust collection box 111 via a third telescopic member 141, and two sets of guide ports 140 that are opened on the side suction frame 142 and are used to cooperate with the connecting pipe 114 to change the collection direction.

[0038] In this embodiment, the side suction component 14 is set to facilitate the collection of dust in the corner of the wall. At the same time, by changing the channel, the airflow speed is higher and the negative pressure is greater when approaching the corner, which can enhance the cleaning effect in this position.

[0039] In detail, when cleaning the corner, the dust collection box 111 is pushed so that one side of the side suction bracket 142 comes into contact with the corner. As the third telescopic member 141 retracts, the guide port 140 on the side suction bracket 142 gradually aligns with the end of the connecting pipe 114, changing the channel position and starting to collect dust from the corner through the side suction bracket 142.

[0040] It should be noted that the channels on both sides of the side suction holder 142 are not connected.

[0041] Furthermore, such as Figure 2 and Figures 8 to 10 As shown, the piercing assembly 15 includes multiple piercing rods 152 that pass through both ends of the side suction frame 142 and are connected to the top via a receiving member 151, multiple second springs 153 that are sleeved on the piercing rods 152 and located between the receiving member 151 and the side suction frame 142, and a trapezoidal block 155 that is connected to the dust collection box 111 via a fourth telescopic member 154 and is used to drive the receiving member 151 to move downward.

[0042] In this embodiment, since dust is extremely prone to becoming damp and hardened after accumulating in the corner, the piercing component 15 can effectively pierce the hardened dust and disperse it into small pieces for collection, thereby ensuring the cleaning effect.

[0043] In detail, while squeezing the side suction frame 142 towards the corner, the trapezoidal block 155 connected to the dust collection box 111 via the fourth telescopic component 154 begins to squeeze the inclined position of the receiving component 151. As the trapezoidal block 155 moves forward, the receiving component 151 drives multiple sets of piercing rods 152 to move downward and pierce the caking dust.

[0044] It should be noted that the elastic potential energy of the fourth telescopic component 154 is greater than that of the second spring 153, thus ensuring that the trapezoidal block 155 will not contract when the compression receiving component 151 moves downward.

[0045] Furthermore, such as Figure 2 and Figures 8 to 10 As shown, the agitation assembly 16 includes a first bracket 161 and a second bracket 162 respectively connected to the inner and outer sides of the side suction frame 142, a transmission ring 163 and a transmission shaft 164 respectively connected to the first bracket 161 and the second bracket 162, a belt drive 165 connected at both ends to the transmission ring 163 and the transmission shaft 164 and passing through the side suction frame 142, a second gear 166 connected to the transmission shaft 164, a second rack 167 connected to the dust collection box 111 and meshing with the second gear 166, a sprocket and chain drive 168 connected to multiple sets of piercing rods 152, and an agitating claw 169 connected to the end of the piercing rod 152.

[0046] In this embodiment, by setting the agitation component 16 in conjunction with the piercing component 15, after the piercing rod 152 moves downward, the agitation claw 169 connected to the end of the piercing rod 152 begins to sweep the dust adhering to the corner of the floor, removing the sticky dust and ensuring that the cleaning work is thorough and leaves no dead corners; the agitation component 16 is provided with a dust cover inside the side suction frame 142, which is not shown in the figure.

[0047] In detail, as the piercing rod 152 is in place and the trapezoidal block continues to move forward, its end begins to contract upon contact with the corner of the wall. Simultaneously, due to the misalignment of the side suction frame 142 and the dust collection box 111, the second gear 166 and the second rack 167 begin to mesh and drive. The second gear 166 drives the transmission ring 163 to rotate through the transmission shaft 164 and the belt drive component 165. The transmission ring 163 then drives the internal piercing rod 152 to rotate. Multiple sets of piercing rods 152 operate synchronously through the sprocket and chain drive component 168, and drive the bottom stirring claw 169 to clean the ground.

[0048] It should be noted that during the process of connecting the side suction frame 142 to the connecting pipe 114, the piercing component 15 and the stirring component 16 are completed in sequence. At the same time, the dust collection box 111 can be pushed back and forth multiple times and staggered by a certain distance, thereby driving the piercing component 15 and the stirring component 16 to work at different points multiple times, improving the cleaning effect of the corner.

[0049] Furthermore, such as Figure 1 and Figures 11 to 12 As shown, the long-distance surface dust negative pressure cleaning device further includes: The connecting mechanism 2 is disposed on the main pipeline 300 and includes a sealing component 21 connected to the main pipeline 300 and a detection component 22 disposed on the main pipeline 300. Before the rake head assembly 11 is connected to the connecting end 200, the detection component 22 checks the blockage inside the main pipe 300. Then, when the rake head assembly 11 is engaged with the corresponding connecting end 200, the sealing component 21 cuts off the internal space of the main pipe 300 at the corresponding position.

[0050] It is worth mentioning that by setting up the connecting mechanism 2, not only can the cleaning efficiency be improved, but the cleaning work can also be guaranteed not to be interrupted due to blockage of the main pipe 300.

[0051] Furthermore, such as Figures 1 to 3 and Figures 5 to 6As shown, the sealing assembly 21 includes multiple sets of first sealing plates 211 connected within the main pipe 300 and corresponding to the connection end 200, a receiving groove 210 opened within the first sealing plate 211, a shaft 213 that passes through the main pipe 300 and the first sealing plate 211 in sequence and is connected to a follower gear 212 at the top, a second sealing plate 214 connected to one end of the shaft 213 and located within the receiving groove 210, a third spring 215 sleeved on the shaft 213 and located between the main pipe 300 and the follower gear 212, a locking frame 216 connected to the main pipe 300 and located outside the connection end 200, an annular cap 217 connected to one end of the connecting pipe 114, a second half gear 218 connected to the connecting pipe 114 and meshing with the follower gear 212, and a locking block 219 connected to the connecting pipe 114 and cooperating with the locking frame 216 to fix the connecting pipe 114.

[0052] In this embodiment, by setting the blocking component 21 to separate the originally long main pipe 300 from the position where it is connected to the sweeping rake, the working space of the main pipe 300 is shortened accordingly, thereby reducing the direct consumption of negative pressure generated by the blower and improving the cleaning effect.

[0053] In detail, during the engagement of the connecting pipe 114 and the connecting end 200, the connecting pipe 114 is first operated so that the annular cap 217 on it presses down on one side of the follower gear 212. At this time, the teeth of the second half gear 218 are located on the side away from the follower gear 212. Then, when the locking block 219 on the connecting pipe 114 is engaged in the slot of the vertical part of the locking frame 216, the teeth of the second half gear 218 just mesh with the follower gear 212. The follower gear 212 also drives the second sealing plate 214 to move out of the receiving slot 210 through the shaft rod 213 and engage with the second half gear 212. Once the sealing plate 211 is integrated, the connecting pipe 114 is rotated 90° to allow the locking block 219 to engage with the arc-shaped groove of the locking frame 216. Simultaneously, the second half gear 218 drives the follower gear 212 to rotate. The follower gear 212 drives the first sealing plate 211 to rotate 90° synchronously via the shaft rod 213 and the second sealing plate 214. Thus, the first sealing plate 211 and the second sealing plate 214 together cut off the space of the main pipe 300. When cleaning is finished, the connecting pipe 114 is rotated in the opposite direction, and the third spring 215 enables the sealing assembly 21 to complete the reset work.

[0054] It should be noted that a connecting valve is installed inside the connecting end 200, which automatically opens after being connected to the connecting pipe 114; one end of the third spring 215 is connected to the main pipe 300, and the other end is a free end; rubber pads are provided on the circumference of the first sealing plate 211 and the second sealing plate 214 to avoid the transmission rope 224 and to provide a sealing function.

[0055] Example 2 like Figure 1 and Figure 11 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows: like Figure 1 and Figure 11 As shown, the detection component 22 includes two sets of fixed pulleys 221 connected to the main pipe 300, a drive wheel 223 connected to the output end of the motor 222, a transmission rope 224 passing through the main pipe 300 and wound around the fixed pulleys 221 and the drive wheel 223, and multiple sets of cleaning blocks 225 connected to the transmission rope 224 and located inside the main pipe 300.

[0056] In this embodiment, by setting the detection component 22 to check and unclog the inside of the main pipe 300 before the cleaning work begins, firstly, it ensures the smooth airflow of the main pipe 300 and prevents blockage from affecting the work. Secondly, it specifically scrapes the area under the first sealing plate 211 and the second sealing plate 214 to ensure the normal operation of the sealing component 21 and avoid the accumulation of dust from affecting the sealing effect.

[0057] In detail, before the rake head assembly 11 engages with the connecting end 200, the motor 222 is started, and the drive wheel 223 at the output end drives the transmission rope 224 to move on the main pipe 300 and the fixed pulley 221, thereby driving multiple cleaning blocks 225 to move and clean the inner wall at the bottom of the main pipe 300, ensuring that there is no dust accumulation below the sealing assembly 21. In addition, the main pipe 300 is provided with an observation window at the connecting end 200, through which the amount of dust pushed by the cleaning blocks 225 can be directly observed. If there is a lot of dust in a certain place, there may be a blockage at the corresponding location. The high-frequency vibrator is used to externally vibrate the corresponding location, thereby dispersing the dust accumulated inside the main pipe 300, and then expelling it through negative pressure, thereby ensuring that the subsequent cleaning work can proceed normally.

[0058] It should be noted that after the inspection is completed, the motor 222 reverses to reset multiple cleaning blocks 225. The cleaning blocks 225 are inclined on both sides to reduce the interception effect of dust. Since the pipeline is long, the location of the blockage can be quickly identified through the cleaning blocks 225. The detection component 22 is equipped with multiple sets.

[0059] Work steps Step 1: Inspection. Before the cleaning mechanism 1 is connected to the main pipe 300, the internal condition of the main pipe 300 is checked by activating the inspection component 22, and the working position of the sealing component 21 is scraped to ensure the sealing effect of the sealing component 21. Step 2: After installation and testing, the locking of the connecting pipe 114 and the connecting end 200 simultaneously drives the sealing component 21 to work, so that the sealing component 21 cuts off the space at the corresponding position inside the main pipe 300, thereby reducing the length of the main pipe 300 involved in cleaning and increasing the negative pressure suction. Step 3: Side cleaning. Workers use the moving rake head assembly 11 to collect dust on the ground under negative pressure. When the machine is at the bottom support position, the rake head assembly 11 is squeezed against the side of the wall. The adjustment assembly 12 is then used to quickly change the orientation of the roller 116, so that it can be in close contact with the side wall for collection. During the process, the disturbance assembly 13 is controlled to disturb the dust accumulated on the side of the wall, thereby improving the collection effect. Step 4: Corner cleaning. When cleaning the corner, the worker presses the side suction component 14 against one side of the corner and then pushes the rake head component 11 to squeeze against the corner, thereby changing the airflow. The dust in the corner begins to be collected from the side suction component 14. At the same time, during the pushing process, the piercing component 15 and the stirring component 16 are used to further disperse the dust that has hardened in the corner, greatly improving the cleaning effect of the corner.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
