Description

Technical Field

[0001] The present invention belongs to the technical field of dust cleaning, and more specifically, particularly relates to a dust cleaning device for intelligent building construction. Background Art

[0002] Building construction covers various links from the basic engineering of the project, such as earth excavation and foundation treatment, to the construction of the main structure, including concrete pouring, masonry, steel structure installation, etc., and then to the decoration stage of the building, such as interior and exterior wall plastering, floor laying, door and window installation, etc. During the construction of each link, due to material cutting, grinding, material separation, etc., a large amount of dust is generated, so it is necessary to handle the dust.

[0003] Chinese Patent Publication No.: CN117259379A, a dust cleaning device for building construction. In this invention, by turning on the fan, the fan provides suction, and the air with dust is sucked into the dust collection box through the dust suction pipe 3 and filtered through the filter screen to achieve the dust removal effect. At the same time, the nozzle of the dust suction pipe is adjusted through the steering mechanism, and the dust suction range of the dust suction pipe 3 can be increased without moving the dust collection box.

[0004] Existing dust suction devices have the following disadvantages:

[0005] 1. The size of the dust suction head of existing dust suction devices cannot be adjusted. In the face of different construction processes, such as brick cutting, wall grinding, and sand and stone separation, the range of dust generation is different. The fixed-size dust suction head diameter is difficult to match different construction processes. If the dust suction head is too large, it may affect the construction work, and if the dust suction head is too small, it may cause incomplete dust adsorption.

[0006] 2. When existing dust suction devices are in use, it is inconvenient to adjust the opening size of the dust suction pipe to adapt to the dust suction head. If the opening of the dust suction head is very large but the pipe diameter is small, it may cause excessive internal pressure in the pipe when a large amount of dust and air are inhaled, damaging the pipe and connecting components. When the opening is very small and the pipe diameter is too large, it may cause insufficient suction and affect dust suction.

[0007] In view of this, research and improvement are carried out on the existing structure and deficiencies, and a dust cleaning device for intelligent building construction is provided with the expectation of achieving a more practical value. Summary of the Invention

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the present invention, by providing a fixed bracket, a motor, a first threaded rod and an adjustable sleeve rod in cooperation, the position adjustment of the dust suction head in the longitudinal and transverse directions can be realized. In the construction scene, dust may be distributed at different heights, such as near cutting equipment, on the surface of high building components, etc. By adjusting the height of the dust suction head, it can be accurately close to the dust source, effectively suck dust at different heights, avoid the problem of incomplete cleaning caused by inappropriate height, and improve the cleaning effect.

[0014] In the present invention, by providing a damping bearing, a rotating shaft and a mounting ring in cooperation, during the actual use of the dust suction head, the angle of the dust suction head can also be adjusted, enabling the dust suction head to adapt to a more complex construction environment, aligning the best angle with the dust source, and adjusting the orientation of the dust suction head according to the air flow direction and intensity, so as to better capture dust and reduce the interference of the air flow on the cleaning work.

[0015] In the present invention, by providing a dust suction head with an adjustable opening size, for different types and distributions of dust, adjusting the opening size of the dust suction head can optimize the dust suction effect. When cleaning a large area of dispersed light dust, enlarging the opening of the dust suction head can increase the dust suction range and improve the cleaning speed; while when cleaning a small area of concentrated heavy dust or particles, narrowing the opening can concentrate the suction force and more effectively suck the dust, enabling the device to adapt to different construction environments for dust suction.

[0016] In the present invention, by providing a second threaded rod, an adjusting ring and an arc-shaped rod in cooperation, the opening size of the dust suction head can be manually controlled and is convenient to adjust. During the construction process, the generation situation of dust is constantly changing. There may suddenly be a large amount of dust, or the distribution and nature of the dust may change. The operator can, according to his own observation and judgment, combined with the actual construction situation, adjust the opening size of the dust suction head at any time, which can be achieved by rotating the second threaded rod forward or backward, so that the dust suction head always maintains the best dust suction state and ensures the efficient progress of the dust cleaning work.

[0017] In the present invention, by providing a linkage rod, a connecting block and a triangular plate in cooperation, when the linkage rod moves upward or downward to drive the opening of the dust suction head to become larger or smaller, the adjusting ball in the throat tube will be driven to move simultaneously, realizing the synchronous change of the throat tube opening. When the opening of the dust suction head becomes larger, it means that there is more dust and a larger adsorption area. At this time, the adjusting ball moves away from the throat tube, making the throat tube opening larger, enabling more air and dust to pass through smoothly. While ensuring the suction force, the dust suction coverage range is increased, and the efficiency of cleaning large-area dust is improved. On the contrary, when facing less dust and small-area adsorption, the device can quickly and accurately adsorb.

[0018] In the present invention, by providing a dust suction head and a Venturi tube for linkage adjustment, while adjusting the opening of the dust suction head, the size of the internal opening of the Venturi tube is driven to be adjusted, enabling the device to automatically adjust the suction force distribution according to the actual dust suction requirements. When the opening of the dust suction head is very large, but the throat tube diameter is small, it may cause excessive internal pressure in the throat tube when a large amount of dust and air are inhaled, resulting in equipment wear. Avoiding the situation where the throat tube and the dust suction head opening do not match may cause air flow turbulence in the pipeline, resulting in increased erosion of the inner walls of the throat tube and the Venturi tube by dust and accelerating pipeline wear, thus protecting the long-term operation of the equipment.

When facing different construction scenarios, the user can also drive the Venturi tube 4 and the dust suction head 5 to rotate by rotating the mounting ring 37, so as to realize the adjustment of the angle of the dust suction head 5. The rotation of the mounting ring 37 drives the rotating shaft 36 to rotate in the damping bearing 35, and the rotation of the rotating shaft 36 is limited through the two damping bearings 35;

[0033] The Venturi tube 4 is fixedly installed on the inner side wall of the mounting ring 37. A throat 41 is provided on the Venturi tube 4. Two communication grooves 42 are penetratingly opened at the side end part of the Venturi tube 4. An adjusting ball 43 is provided on the inner side wall of the throat 41.

At least two bent grooves 71 are penetratingly opened at the side end part of the adjusting ring 7. An arc-shaped rod 72 is fixedly installed at the circumferential end part of the adjusting ring 7. The arc-shaped rod 72 is slidably installed on the inner side wall of the side groove 51. An arc-shaped groove 73 is penetratingly opened at the side end part of the arc-shaped rod 72. A fixed ring 76 is fixedly installed on the inner side wall of the suction head 5. At least two inclined guide grooves 77 are penetratingly opened at the side end part of the fixed ring 76. At least two adjusting pieces 74 are provided on the adjusting ring 7 and the fixed ring 76. Plug rods 75 are fixedly installed at both side end parts of each adjusting piece 74. Each plug rod 75 is respectively slidably installed on the inner side walls of the bent groove 71 and the inclined guide groove 77. The movement of the arc-shaped rod 72 drives the adjusting ring 7 to rotate inside the suction head 5. The rotation of the adjusting ring 7 will drive the rotation of each bent groove 71. The rotation of each bent groove 71 will move through the plug rod 75. The movement of each plug rod 75 will drive the movement of each adjusting piece 74. And the plug rods 75 on the other side are all located in the inclined guide grooves 77. At this time, each adjusting piece 74 will gradually slide along the track of the inclined guide groove 77. At this time, the opening at the suction head 5 gradually expands. The user can adjust the opening at the suction head 5 to an appropriate size for construction treatment;

[0034] A connecting block 81 is fixedly installed at the side end part of the linkage rod 8. A push rod 83 is fixedly installed at the side end part of the connecting block 81. The push rod 83 is slidably installed on the inner side wall of the arc-shaped groove 73. After the position of the suction head 5 is adjusted, the user can adjust the opening of the suction head 5 according to the specific construction environment. When the user adjusts the opening of the suction head 5, as shown in Figure 6 and Figure 7 shown, at this time each adjusting piece 74 is in the initial state, that is, the suction head 5 is in the closed state. When the user needs to open the opening of the suction head 5, the second threaded rod 54 can be rotated. The rotation of the second threaded rod 54 drives the connecting block 81 to move upward through the second thread groove 82. The upward movement of the connecting block 81 drives the push rod 83 to move upward. The upward movement of the push rod 83 in the arc-shaped groove 73 drives the arc-shaped rod 72 to slide in the side groove 51;

[0035] The upper end of the connecting block 81 is penetrated and provided with a second threaded groove 82, the second threaded rod 54 is rotationally installed on the inner side wall of the second threaded groove 82, the upper end of the linkage rod 8 is penetrated and provided with a cylindrical groove 84, a triangular plate 85 is fixedly installed at the upper end of the linkage rod 8, the linkage rod 8 slides on the circumferential end of the vertical rod 61 through the cylindrical groove 84. When the connecting block 81 moves upward, it will drive the linkage rod 8 to move upward. When the linkage rod 8 moves upward, it will drive the triangular plate 85 to move upward. When the triangular plate 85 moves upward, it will push the transmission rod 48 to gradually move away from the position of the Venturi tube 4. The movement of the transmission rod 48 will drive the connecting rod 47 to move. The movement of the connecting rod 47 will drive the adjusting ball 43 to move in the throat 41. At this time, the telescopic rod 45 and the spring 46 are both compressed. The farther the adjusting ball 43 moves away from the inner wall of the throat 41, the larger the opening in the throat 41. The larger the opening of the throat 41, that is, the slower the air flow velocity. The smaller the opening of the throat 41, that is, the faster the air flow velocity. Furthermore, when the connecting block 81 drives the push rod 83 to move upward and drives the adjusting ring 7 to rotate so that the opening of the dust suction head 5 is larger, the upward movement of the linkage rod 8 will drive the triangular plate 85 to move, driving the adjusting ball 43 to slide farther in the throat 41, making the flow velocity at the throat 41 larger.

[0036] Working principle:

[0037] First step, at the construction site of building construction, when carrying out work such as brick cutting, sand separation, and wall surface grinding, a certain amount of dust will be generated at the work site. The user can push the moving support 1 to drive the device to move to the area where dust needs to be processed, adjust the dust suction head 5 to the position where dust suction and dust removal are required, adjust the opening of the dust suction head 5 to an appropriate size, and start the dust suction box 2 to carry out dust suction.

[0038] Second step, before the user carries out dust suction treatment on the dust at the construction site, the user can first adjust the position of the dust suction head 5. When adjusting the height of the dust suction head 5, the user can drive the first threaded rod 14 to rotate forward or reversely by driving the motor 13. The rotation of the first threaded rod 14 will drive the movable rod 3 to move upward or downward through the first threaded groove 31. The movement of the movable rod 3 will drive the two fixing parts 34 to move upward or downward through the two movable blocks 32 and the adjustable sleeve rod 33. The movement of the two fixing parts 34 will drive the dust suction head 5 at the side end of the Venturi tube 4 to move upward or downward through the rotating shaft 36 and the mounting ring 37. After adjusting the height of the dust suction head 5 to an appropriate position, the user can turn off the motor 13. The user can also adjust the position of the dust suction head 5 by adjusting the lengths of the two adjustable sleeve rods 33. When facing different construction scenarios, the user can also drive the Venturi tube 4 and the dust suction head 5 to rotate by rotating the mounting ring 37, so as to realize the adjustment of the angle of the dust suction head 5. The rotation of the mounting ring 37 drives the rotating shaft 36 to rotate in the damping bearing 35, and the limit of the rotation of the rotating shaft 36 is realized through the two damping bearings 35.

[0039] By arranging a fixed bracket 11, a motor 13, a first threaded rod 14 and an adjustable sleeve rod 33 in cooperation, the device can adjust the position of the dust suction head 5 longitudinally and transversely. In the construction scene, dust may be distributed at different heights, such as near cutting equipment, on the surface of building components at high places, etc. By adjusting the height of the dust suction head 5, it can be accurately close to the dust source, effectively suck the dust at different heights, avoid the problem of incomplete cleaning caused by inappropriate height, and improve the cleaning effect;

[0040] By arranging a damping bearing 35, a rotating shaft 36 and a mounting ring 37 in cooperation, during the actual use of the dust suction head 5, the angle of the dust suction head 5 can also be adjusted, enabling the dust suction head 5 to adapt to a more complex construction environment, aligning the best angle with the dust source, and adjusting the orientation of the dust suction head 5 according to the air flow direction and intensity to better capture the dust and reduce the interference of the air flow on the cleaning work;

[0041] In the third step, after completing the adjustment of the position of the dust suction head 5, the user can adjust the opening of the dust suction head 5 according to the specific construction environment. When the user adjusts the opening of the dust suction head 5, as shown in Figure 6 and Figure 7 shown, at this time each adjusting piece 74 is in the initial state, that is, the dust suction head 5 is in the closed state. When the user needs to open the opening of the dust suction head 5, the second threaded rod 54 can be rotated. The rotation of the second threaded rod 54 drives the connecting block 81 to move upward through the second thread groove 82. The upward movement of the connecting block 81 drives the push rod 83 to move upward. The push rod 83 moves upward in the arc groove 73 to drive the arc rod 72 to slide in the side groove 51. The movement of the arc rod 72 drives the adjusting ring 7 to rotate in the dust suction head 5. The rotation of the adjusting ring 7 will drive each bent groove 71 to rotate. The rotation of each bent groove 71 will move through the insertion rod 75. The movement of each insertion rod 75 will drive each adjusting piece 74 to move. And the insertion rods 75 on the other side are all located in the inclined guide groove 77. At this time, each adjusting piece 74 will gradually slide along the track of the inclined guide groove 77. At this time, the opening at the dust suction head 5 gradually expands. The user can adjust the opening at the dust suction head 5 to an appropriate size for construction treatment;

[0042] By arranging a dust suction head 5 with an adjustable opening size, for different types and distributions of dust, adjusting the opening size of the dust suction head 5 can optimize the dust suction effect. When cleaning a large area of dispersed light dust, enlarging the opening of the dust suction head 5 can increase the dust suction range and improve the cleaning speed; while when cleaning a small area of concentrated heavy dust or particles, reducing the opening can concentrate the suction force and more effectively suck the dust, enabling the device to adapt to different construction environments for dust suction;

[0043] By setting up the cooperation of the second threaded rod 54, the adjusting ring 7 and the arc rod 72, the opening size of the dust suction head 5 can be manually controlled and is convenient to adjust. During the construction process, the generation of dust is constantly changing. There may suddenly be a large amount of dust, or the distribution and properties of the dust may change. The operator can, based on their own observation and judgment, combined with the actual construction situation, adjust the opening size of the dust suction head 5 at any time, which can be achieved by rotating the second threaded rod 54 forward or backward, so that the dust suction head 5 always maintains the best dust suction state and ensures the efficient progress of the dust cleaning work;

[0044] In the fourth step, when the connecting block 81 moves upward, it will drive the linkage rod 8 to move upward. The upward movement of the linkage rod 8 will drive the triangular plate 85 to move upward. The upward movement of the triangular plate 85 will push the transmission rod 48 to gradually move away from the venturi tube 4. The movement of the transmission rod 48 will drive the connecting rod 47 to move. The movement of the connecting rod 47 will drive the adjusting ball 43 to move within the throat tube 41. At this time, the telescopic rod 45 and the spring 46 are both compressed. The farther the adjusting ball 43 moves away from the inner wall of the throat tube 41, the larger the opening in the throat tube 41. The larger the opening in the throat tube 41, that is, the slower the air flow velocity. The smaller the opening in the throat tube 41, that is, the faster the air flow velocity. Furthermore, when the connecting block 81 drives the push rod 83 to move upward and drives the adjusting ring 7 to rotate so that the opening of the dust suction head 5 becomes larger, the upward movement of the linkage rod 8 will drive the triangular plate 85 to move, driving the adjusting ball 43 to slide farther within the throat tube 41, making the flow velocity at the throat tube 41 larger;

[0045] By setting up the cooperation of the linkage rod 8, the connecting block 81 and the triangular plate 85, when the upward or downward movement of the linkage rod 8 drives the opening of the dust suction head 5 to be adjusted larger or smaller, it will simultaneously drive the adjusting ball 43 within the throat tube 41 to move, realizing the synchronous change of the opening of the throat tube 41. When the opening of the dust suction head 5 becomes larger, it means there is more dust and a larger adsorption area. At this time, the adjusting ball 43 moves away from the throat tube 41, making the opening of the throat tube 41 larger, which can allow more air and dust to pass through smoothly. While ensuring the suction force, it increases the dust suction coverage area and improves the efficiency of large-area dust cleaning. On the contrary, when there is less dust and a small-area adsorption, the device can quickly and accurately adsorb;

[0046] The device is provided with a dust collector head 5 and a venturi tube 4 for linkage adjustment. When the opening of the dust collector head 5 is adjusted, the size of the internal opening of the venturi tube 4 is also adjusted, so that the device can automatically adjust the suction force distribution according to the actual dust collection demand. When the opening of the dust collector head 5 is large, but the diameter of the throat 41 is small, the internal pressure of the throat 41 may be too high when a large amount of dust and air are inhaled, causing the equipment to wear. To avoid the mismatch between the throat 41 and the opening of the dust collector head 5, the airflow may be turbulent in the pipeline, resulting in the dust aggravating the scouring of the throat 41 and the inner wall of the venturi tube 4, accelerating the wear of the pipeline, and protecting the long-term operation of the equipment.
