Description

Technical Field

[0001] This invention relates to the field of dust removal devices for building construction, and particularly to a dust removal device for building construction. Background Technology

[0002] Construction dust control equipment is a device specifically designed to solve the problem of dust pollution at construction sites. With rapid urbanization, construction activities are becoming increasingly frequent, and the resulting dust has a significant impact on air quality, the surrounding environment, and worker health. Construction work not only includes outdoor operations but also leaves thick layers of dust on the ground after indoor work. During manual cleaning, this dust is inevitably re-ignited, affecting the workers' working environment and the cleanliness of the indoor areas. Therefore, in current technological applications, cleaning machines are used in most cases to solve this problem.

[0003] However, the cleaning machine has the following technical problems in use. During the settling process, dust combines with some waste materials in the room, causing the dust to clump together. Existing cleaning machines mostly have a single rotating cleaning structure, which has limited ability to break up this clumping, making it impossible to quickly clean it. This results in some dust residue remaining in the cleaning path, requiring the machine to clean repeatedly, reducing dust removal efficiency. Furthermore, to ensure a cleaning range, existing cleaning machines often have very large individual cleaning structures, reducing the cleaning effect on the edges of the structures. This again requires workers to repeatedly clean the covered area, further reducing dust removal efficiency. Summary of the Invention

[0004] The main objective of this invention is to provide a dust removal device for construction work, which aims to reduce the dust residue rate after a single pass, expand the cleaning range, and improve dust removal efficiency.

[0005] To achieve the above objectives, the present invention provides a dust removal device for construction sites, comprising: The cleaning machine body has a dust suction port at the front end for absorbing dust in the building. Several air blowing pipes are provided below the dust suction port to raise the building dust for easy suction. The cleaning machine body has a traveling component at the bottom, which includes traveling wheels and guide wheels. The scrubbing assembly is disposed on one side of several air pipes and is used to scrub the agglomerated dust. The scrubbing assembly includes two scrubbing discs that move in opposite directions, and each scrubbing disc is slidably connected to the underside of the cleaning machine body. A transmission system, which is disposed between the traveling wheel and the scrubbing assembly, is used to control the reciprocating motion of the two scrubbing discs by the driving force of the traveling wheel; A material-aggregating strip is disposed on the side of the cleaning machine body away from the scrubbing components, and an exhaust fan is fixedly connected between the material-aggregating strip and the cleaning machine body.

[0006] In one possible implementation, the scrubbing assembly further includes: A limiting plate is slidably connected to the lower side of the cleaning machine body. A limiting cylinder is fixedly connected to the lower side of the limiting plate. A transmission plate is hinged to both sides of the limiting cylinder. A transmission groove is opened on each of the transmission plates. The scrubbing disc abuts against the inner wall of each transmission groove. The linkage plate is rotatably connected between the cleaning machine body and the limiting plate. The non-center position of the linkage plate abuts against the slot on the limiting plate, which is used to drive the back-and-forth reciprocating motion of the limiting plate.

[0007] In one possible implementation, the underside of the scrubbing disc is provided with several scrubbing strips and several scrubbing protrusions.

[0008] In one possible implementation, each of the scrubbing discs is coaxially and fixedly connected to a transmission gear on the side facing the cleaning machine body, each of the transmission gears is meshed with a transmission rack on one side, and each of the transmission racks is fixedly connected to the lower side of the cleaning machine body.

[0009] In one possible implementation, an elastic column is slidably connected to the limiting cylinder, and a scrubbing block is fixedly connected to the end of the elastic column away from the scrubbing disc. A limiting spring is connected between the end of the elastic column away from the scrubbing block and the limiting cylinder.

[0010] In one possible implementation, a dustproof plate is fixedly connected to the main body of the cleaning machine near the dust suction port.

[0011] In one possible implementation, the transmission system includes: A first gear and a second gear mesh with each other. The first gear is rotatably connected to the lower side of the washing machine body, and the second gear is fixedly connected to the shaft between the second gear and the travel wheel. The chain drive includes a first sprocket and a second sprocket. The first sprocket is coaxially and fixedly connected to the linkage disc, and the second sprocket is coaxially and fixedly connected to the first gear.

[0012] This invention's technical solution incorporates a dust suction port and multiple air blowing pipes on the main body of the cleaning machine. The former absorbs dust, while the latter raises dust as the machine moves, allowing it to be better captured by the suction port. This preliminary treatment effectively reduces the workload of the subsequent scrubbing components and improves the cleaning efficiency for stubborn dust. The scrubbing components consist of two opposing scrubbing discs, expanding the cleaning range compared to traditional single-scrubbing structures. They also effectively break up clumps of dust by generating shearing and compressive forces. In the transmission system, the driving force of the traveling wheels is converted into the reciprocating motion of the scrubbing discs, further enhancing cleaning efficiency. The aggregate strip design effectively gathers unraised dust, and through the negative pressure adsorption of the exhaust fan, forms a complete dust removal process, including pre-raising, mechanical scrubbing, and secondary adsorption, significantly reducing the dust residue rate after a single pass. This equipment not only reduces dust dispersion into the surrounding environment but also improves air quality at the construction site, enhancing worker health. In addition, the efficient design and optimized transmission system of the cleaning machine enable it to operate well in environments with different types of dust, which helps reduce energy consumption and downtime, thereby extending operating time and improving overall economic efficiency.

[0016] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0018] This invention proposes a dust removal device for building construction.

[0019] Example 1 Reference Figures 1 to 7 It includes the cleaning machine body 1, scrubbing components, transmission system and aggregate strip 14: The dust suction port 11 for absorbing dust in the building is located at the front end of the cleaning machine body 1. Several air blowing pipes 12 for raising building dust so that the dust suction port 11 can be absorbed are fixedly located below the dust suction port 11. The traveling component is located below the cleaning machine body 1. The traveling component includes a traveling wheel 13 and a guide wheel 131. During the movement of the cleaning machine body 1, the air blowing pipe 12 and the dust suction port 11 pre-lift and adsorb, which initially loosens and partially absorbs the deposited and agglomerated dust before the scrubbing components operate, reducing the working load of the scrubbing disc 21 and indirectly improving the efficiency of the scrubbing components in breaking up stubborn agglomerated dust.

[0020] The scrubbing assembly is located on one side of several air pipes 12 and is used to scrub the agglomerated dust. The scrubbing assembly includes two scrubbing discs 21 that move in opposite directions. Each scrubbing disc 21 is slidably connected to the lower side of the cleaning machine body 1. First, during the movement of the cleaning machine body 1, the pre-lifting and adsorption effect of the air blowing pipe 12 and the dust suction port 11 can initially loosen and partially absorb the agglomerated dust deposited along the travel path. This preliminary treatment significantly reduces the workload of the scrubbing disc 21, thereby improving the efficiency of the scrubbing assembly in dispersing stubborn dust. Second, the scrubbing assembly of the cleaning machine body 1 uses two scrubbing discs 21 that move in opposite directions, which expands the scrubbing coverage area of ​​a single travel path compared to the traditional single scrubbing structure. In addition, the shearing and compressive forces generated by the opposite movement achieve efficient dispersal of stubborn agglomerated dust.

[0021] A transmission system for controlling the reciprocating motion of the two scrubbing discs 21 by the driving force of the travel wheel 13 is disposed between the travel wheel 13 and the scrubbing assembly. The material gathering strip 14 is located on the side of the cleaning machine body 1 away from the scrubbing components, and the exhaust fan 15 is fixedly connected between the material gathering strip 14 and the cleaning machine body 1.

[0022] The material-gathering strip 14, with its curved shape, collects dust particles that haven't been dispersed. Combined with the negative pressure adsorption of the exhaust fan 15, this achieves a complete dust removal process: pre-dispersal adsorption, mechanical scrubbing and dispersion, and secondary adsorption, significantly reducing dust residue after each pass. The material-gathering strip 14, combined with the negative pressure adsorption of the exhaust fan 15, creates a localized dust interception zone, preventing the dispersed dust from escaping to the surrounding area. Reduced dust residue not only improves operational efficiency but also directly improves air quality at the construction site, significantly impacting worker health. Furthermore, the dual scrubbing discs 21 enhance the equipment's adaptability to different types of dust environments, enabling effective use under various construction conditions. By reducing secondary dust generation, the equipment can also be used in more sensitive environments, such as indoor construction sites, minimizing environmental impact. Ultimately, the efficient design of the cleaning machine reduces energy and time investment, effectively lowering operating costs and improving overall economic benefits.

[0023] The transmission system converts the driving force of the traveling wheel 13 into the reciprocating motion power of the scrubbing disc 21. By adding a drive motor to the scrubbing assembly and coordinating with manual operation, the energy consumption of the equipment is reduced. Furthermore, the synergistic effect of manual pushing and the equipment's own driving force reduces the load and power consumption of the travel drive module, solving the problem of frequent charging interruptions caused by traditional equipment in factory dust removal. This extends the continuous operation time after a single charge and improves overall dust removal efficiency.

[0024] Reference Figures 2 to 5 The scrubbing assembly also includes a limiting plate 22 and a linkage plate 25. The limiting plate 22 is slidably connected to the lower side of the washing machine body 1, the limiting cylinder 23 is fixedly connected to the lower side of the limiting plate 22, the two transmission plates 24 are respectively hinged to the two sides of the limiting cylinder 23, the transmission groove 241 is opened on the transmission plate 24, and the scrubbing disc 21 abuts against the inner wall of each transmission groove 241. The linkage plate 25 is rotatably connected between the cleaning machine body 1 and the limiting plate 22. The non-center position of the linkage plate 25 abuts against the groove on the limiting plate 22, which is used to drive the back and forth reciprocating motion of the limiting plate 22.

[0025] The linkage disc 25 is driven to rotate by the transmission system, and then abuts against the groove on the limiting plate 22 at its non-center position. This causes the limiting plate 22 to slide back and forth along the sliding direction of the lower side of the cleaning machine body 1. Based on this, the two wiping discs 21 on both sides slide back and forth in a regular manner, thereby effectively wiping the dust clumps on the travel path of the cleaning machine body 1. This makes the force of the wiping discs 21 on the dust clumps more stable, avoiding component wear caused by excessive local force, and improving the efficiency of dispersing the clumps of dust. The two transmission plates 24 are symmetrically hinged to both sides of the limiting cylinder 23, driving the corresponding wiping discs 21 to move back and forth in opposite directions synchronously. This ensures that the wiping area on the single travel path is evenly covered, avoiding dust removal dead corners caused by asynchronous movement of the wiping discs, and further improving the dust removal effect of a single operation.

[0026] Reference Figures 2 to 3 Several scraping strips 211 and several scraping protrusions 212 are provided on the lower side of the scrubbing disc 21.

[0027] The strip-shaped protrusions of the scraping strips 211 and the dot-shaped protrusions of the scraping bosses 212 form a composite line-point contact, which significantly increases the contact area and contact pressure with agglomerated dust compared to the smooth surface of the scrubbing disc. Through the combined action of squeezing, shearing, and scraping, dust agglomerates of different hardness and thickness can be quickly broken up. The staggered distribution of the scraping strips 211 and the scraping bosses 212 allows for multiple impacts and scrapings on dust agglomerates in the same area during the reciprocating motion of the scrubbing disc 21, further improving the efficiency of agglomerated dust dispersal and reducing dust residue.

[0028] The linear extension structure of the scraping strip 211 can cover the radial working area of ​​the scrubbing disc 21, and the dotted distribution of the scraping protrusions 212 can fill the gaps between the scraping strips, forming a full-area scrubbing coverage without dead corners, avoiding the omission of local dust clumps caused by the smooth surface of the scrubbing disc, and ensuring that the dust clumps on the single travel route are fully treated.

[0029] The raised structure of the scrubbing strip 211 and the scrubbing boss 212 adopts a non-full-coverage design. Compared with the overall raised scrubbing disc surface, it reduces the contact area with the ground, reduces the frictional resistance during the reciprocating motion of the scrubbing disc 21, and, together with the power reuse design of the transmission system, further reduces the energy consumption of the equipment and extends the operating time.

[0030] Reference Figures 2 to 5 Each scrubbing disc 21 is coaxially and fixedly connected to the transmission gear 31 on the side facing the cleaning machine body 1. Each transmission gear 31 meshes with the transmission rack 32, and each transmission rack 32 is fixedly connected to the lower side of the cleaning machine body 1.

[0031] The meshing of the transmission gear 31 and the transmission rack 32 causes the scrubbing disc 21 to undergo a rotational motion on top of its original reciprocating linear motion, forming a combined action mode of reciprocating scraping and rotational crushing. Compared to single reciprocating motion, this combined motion can generate multi-directional shearing, compressive, and crushing forces on agglomerated dust, enabling rapid breakup of dense dust agglomerates with high hardness and high density.

[0032] The rotational motion drives the scraping strip 211 and the scraping boss 212 to dynamically impact the dust clumps, avoiding the attenuation of force at local positions during reciprocating motion, and further improving the removal effect of dust clumps in hidden gaps.

[0033] The rotational motion of the scrubbing disc 21 expands the effective area of ​​the scrubbing strips 211 and the scrubbing protrusions 212 from linear coverage to area coverage. Combined with the stroke coverage of the reciprocating linear motion, it greatly increases the effective scrubbing area on a single travel path, reduces the number of reciprocating operations of the equipment, and improves the overall dust removal efficiency.

[0034] The reciprocating movement of the scrubbing disc 21 is achieved through the meshing transmission of the transmission gear 31 and the transmission rack 32, causing the scrubbing disc 21 to rotate during movement. This eliminates the need for additional drive equipment, simplifies energy consumption, and reduces manufacturing costs.

[0035] Reference Figures 4 to 5 The elastic column 41 is slidably connected to the limiting cylinder 23. The end of the elastic column 41 away from the scrubbing disc 21 is fixedly connected to the scrubbing block 42. The limiting spring 43 is connected between the end of the elastic column 41 away from the scrubbing block 42 and the limiting cylinder 23.

[0036] The scrubbing block 42 is specifically designed to compensate for the problem of reduced scrubbing force in the middle area when the two scrubbing discs 21 move towards each other. During the scrubbing process of the two scrubbing discs 21, the scrubbing effect in the middle position may be worse than that on both sides. Therefore, the scrubbing block 42 is added to the middle travel path to supplement the scrubbing of a certain area.

[0037] Then, a limiting spring 43 was added. Since the level accuracy of the construction site is generally not guaranteed, the distance between the scrubbing block 42 and the ground will change when the cleaning machine body 1 moves. Therefore, the limiting spring 43, together with the sliding connection structure of the elastic column 41, can buffer the impact force of the scrubbing block 42 against the ground protrusion, reduce component wear, and extend the service life of the scrubbing components.

[0038] The supplementary scrubbing function of the scrubbing block 42 works in synergy with the reciprocating scraping and rotating crushing of the scrubbing disc 21 to perform secondary treatment on the dust clumps that have been initially broken up by the scrubbing disc. In particular, it targets the residual clumps in the middle area that have not been completely broken up, achieving efficient dust removal with double crushing and full coverage, and improving the overall dust removal efficiency.

[0039] Reference Figures 1 to 4 The dustproof plate 16 is fixedly connected to the main body 1 of the cleaning machine near the dust suction port 11.

[0040] The dustproof plate 16 can physically block and guide the airflow of dust raised by the blowing pipe 12, preventing some dust from escaping the adsorption range of the suction port 11 due to airflow diffusion, and forcing the raised dust to concentrate and flow into the adsorption area of ​​the suction port 11, directly improving the dust capture rate of the blowing and suction linkage.

[0041] The dustproof plate 16 can prevent dust that is not absorbed in time from spreading towards the operator, reducing the direct contact of dust with the human respiratory tract and skin, improving the on-site environment for dust removal operations in construction, meeting the humanized design requirements of the equipment, and improving the safety and environmental friendliness of the equipment.

[0042] The guiding function of the dustproof plate 16 can make the adsorption airflow of the dust suction port 11 form a more stable negative pressure area, preventing the dust from being raised and settling back to the ground due to the turbulent airflow, thus preventing secondary dust. This works in synergy with the mechanical crushing of the subsequent scrubbing components and the gathering and adsorption of the material strip 14, further ensuring the dust removal effect of a single travel route.

[0043] Reference Figures 6 to 7 The transmission system includes a first gear 51 and a second gear 52 that mesh with each other, and a first sprocket 53 and a second sprocket 54 driven by a chain. The first gear 51 is rotatably connected to the lower side of the cleaning machine body 1, and the second gear 52 is fixedly connected to the shaft between the traveling wheel 13; The first sprocket 53 is coaxially and fixedly connected to the linkage disc 25, and the second sprocket 54 is coaxially and fixedly connected to the first gear 51.

[0044] Through gear meshing and sprocket transmission in the transmission system, the rotational force of the traveling wheel 13 is transmitted to the linkage disc 25, thereby causing the wiping discs 21 on both sides to reciprocate. This allows the wiping discs 21 on both sides to wipe along with the movement of the cleaning machine body 1, thus coordinating the movement of the cleaning machine body 1 with the wiping components and improving the linkage.

[0045] Reference Figures 6 to 7 The first sprocket 53 and the second sprocket 54 maintain a certain wheel diameter ratio. This ratio controls the reciprocating scrubbing speed of the scrubbing disc 21 during the movement of the cleaning machine body 1, allowing for adjustment of the wheel diameter ratio based on actual conditions. To meet different working conditions, the wheel diameter ratio is adjusted to achieve the best scrubbing effect. In areas with thick, hard dust clumps, the wheel diameter ratio is increased to improve the reciprocating speed of the scrubbing disc 21, enhancing the shearing and crushing effect. In areas with thin, easily cleaned dust clumps, the wheel diameter ratio is decreased to reduce the scrubbing speed, thereby reducing equipment energy consumption and ground wear.
