Description

Technical Field

[0001] This invention relates to the field of construction dust control technology, specifically to a ground dust control device for construction sites. Background Technology

[0002] At construction sites, activities such as material transportation, earthwork excavation, and mechanical operations generate a large amount of dust on the ground. This dust not only poses a serious threat to the health of construction workers, causing respiratory diseases, but also pollutes the surrounding environment and affects air quality. Therefore, it is crucial to effectively control dust on the ground at construction sites. Currently, the most common method for dust removal at construction sites is sweeping machines. While sweeping machines can clean the ground, they are prone to generating secondary dust during the cleaning process, resulting in low dust removal efficiency. Furthermore, they are not adaptable to ground surfaces with varying flatness and cannot effectively remove dust from depressions. Therefore, it is necessary to improve this feature.

[0003] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Summary of the Invention

[0004] The purpose of this invention is to provide a dust removal device for construction sites, in order to solve the problems mentioned in the background art, such as the easy generation of secondary dust during the cleaning process, low dust removal efficiency, and difficulty in cleaning dust in depressions with different flatness.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A dust removal device for construction sites, comprising: The cleaning unit includes a cleaning component for rotating and cleaning dust on the ground, and an adjustment component located on one side of the cleaning component for adjusting the angle of the cleaning component to remove dust generated during the cleaning process.

Multiple sets of rotating rollers are rotatably mounted below the drag block to support and guide its movement. The sweeping brushes are evenly distributed at the lower end of the turntable and are used to sweep the dust on the ground. The plane at the lower end of the sweeping brushes is lower than the lower end of the rotating roller and is used to clean the dust on the ground. The air guide block is fixedly connected inside the receiving groove near the exhaust pipe, and the air guide block is arranged in a figure-eight pattern.

[0007] Furthermore, the cleaning assembly also includes: A protrusion is provided on one side of the drag block located in the exhaust pipe; The guide wheel is rotatably connected to the lower corner of the protrusion and is used to support and guide the protrusion.

[0008] Furthermore, the adjustment components include: The mounting base is fixedly connected to the upper end of the drag block and located on one side of the drive motor. A shaft is fixedly connected between the upper openings of the mounting base. A collar is rotatably fitted onto the outside of the shaft between the openings of the mounting base; The push-pull rod is fixedly connected to the outside of the collar and is used to adjust the angle of the cleaning assembly.

[0009] Furthermore, the vacuuming unit also includes a connecting mechanism disposed between the exhaust pipe and the protrusion, the connecting mechanism comprising: A sleeve is fitted over the lower end of the exhaust pipe; A hinge shaft is fixedly connected to the lower part of the outer side of the sleeve, and a hinge hole for limiting the hinge shaft is provided on the outer side of the protrusion.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figure 1-7 The present invention provides a technical solution: A dust removal device for construction sites, comprising: The cleaning unit 1 includes a cleaning component 11 for rotating and cleaning dust on the ground, and an adjustment component 12 located on one side of the cleaning component 11 for adjusting the angle of the cleaning component 11 to remove the dust generated during the cleaning process. The dust collection unit 2 includes an exhaust pipe 21 located on one side of the cleaning assembly 11 for providing a negative pressure state inside the cleaning assembly 11, a dust collection cylinder 24 located at the air outlet of the exhaust pipe 21 for filtering the drawn-in air, and an exhaust fan 25 located on the upper part of the dust collection cylinder 24 for continuously drawing air into and out of the dust collection cylinder 24.

[0017] It should be noted that: by pushing the exhaust pipe 21, the cleaning component 11 moves forward along the ground. The cleaning component 11 sweeps the dust accumulated on the ground and draws it into the dust collection cylinder 24 through the exhaust pipe 21 for filtration. If there is a lot of dust accumulation that causes dust to be stirred up during the cleaning process, the adjustment component 12 can be pulled to rotate the cleaning component 11 relative to the exhaust pipe 21 at a certain angle. This ensures that the exhaust port at the bottom of the cleaning component 11 quickly and timely sucks the stirred-up dust into the dust collection cylinder 24, preventing dust from spreading everywhere and threatening the health of the construction workers.

[0018] As an improvement, such as Figure 1-3 As shown, the cleaning assembly 11 includes: A drag block 111, the lower end of which is provided with a receiving groove 1112; The drive motor 112 is installed at the middle of the upper end of the drag block 111; A turntable 113 is disposed inside the receiving groove 1112, and the upper end of the turntable 113 is connected to the driving end of the drive motor 112. Multiple sets of rotating rollers 1111 are rotatably disposed at the lower part of the drag block 111, which are used to support the drag block 111 and guide the movement of the drag block 111. Sweeping brushes 114 are evenly distributed at the lower end of the turntable 113 and are used to sweep dust off the ground. The plane at the lower end of the sweeping brushes 114 is lower than the lower end of the rotating roller 1111 and is used to clean dust off the ground. The air guide block 115 is fixedly connected inside the receiving groove 1112 near the exhaust pipe 21, and the air guide block 115 is arranged in a figure-eight pattern.

[0019] Furthermore, such as Figure 1 As shown, the cleaning assembly 11 further includes: A protrusion 116 is provided on one side of the drag block 111 located in the exhaust pipe 21; The guide wheel 1162 is rotatably connected at the lower corner of the protrusion 116 and is used to support and guide the protrusion 116.

[0020] Furthermore, the adjustment component 12 includes: Mounting base 121 is fixedly connected to the upper end of the drag block 111 and located on one side of the drive motor 112. A shaft is fixedly connected between the upper openings of the mounting base 121. The collar 122 is rotatably sleeved on the outside of the shaft between the openings of the mounting base 121; The push-pull rod 123 is fixedly connected to the outside of the collar 122 and is used to adjust the angle of the cleaning assembly 11.

[0021] As an improvement, such as Figure 1 , Figure 5 As shown, the vacuuming unit 2 further includes a connecting mechanism 22 disposed between the exhaust pipe 21 and the protrusion 116, the connecting mechanism 22 including: Sleeve 221 is fitted onto the lower end of the exhaust pipe 21; The hinge shaft 222 is fixedly connected to the lower outer side of the sleeve 221, and the outer side of the protrusion 116 is provided with a hinge hole 1161 for limiting the hinge shaft 222. The flexible hose 223 is connected at one end to the exhaust pipe 21 and at the other end to the inside of the receiving groove 1112.

[0022] Furthermore, such as Figure 6-7 As shown, the outer side of the dust collection cylinder 24 is provided with an air inlet 243 that communicates with the air outlet of the exhaust pipe 21; The dust collection cylinder 24 is equipped with a dust filter 244 for filtering the air entering through the air inlet 243; A handle 23 is provided on one side of the dust collection cylinder 24 for fastening the dust collection cylinder 24 to the exhaust fan 25; A pin is slidably provided on one side of the bottom opening of the exhaust fan 25 to lock the dust collection cylinder 24. This pin is used to lock and position the dust collection cylinder 24 after installation, preventing the dust collection cylinder 24 from slipping out of the bottom opening of the exhaust fan 25. The pin is not shown in the figure.

[0023] Furthermore, the dust collection cylinder 24 is provided with guide grooves 241 on the outside, and two sets of guide grooves 241 are arranged in parallel. A limiting groove 242 is provided on the outer side of the dust collection cylinder 24 and below it between the two sets of guide grooves 241; The handle 23 is located on one side of the dust collection cylinder 24 and is used to insert into the guide groove 241 to limit the position of the dust collection cylinder 24. A card seat 233 is fixedly connected to one side of the handle 23 and between the two sets of guide rods 232, which is used to insert into the limiting groove 242 to lock the dust collection cylinder 24. One side of the grip 23 is provided with a limiting bracket 231 for locking and limiting the push-pull rod 123.

[0024] It should be noted that: in the specific implementation process of this invention, such as Figure 1-3 As shown, when dust is swept and collected on the ground, the exhaust fan 25 and drive motor 112 are started simultaneously. The exhaust fan 25 performs exhaust work, so that the air below the receiving tank 1112 passes through the hose 223, exhaust pipe 21, dust collection cylinder 24, and dust filter 244 in sequence, enters the exhaust fan 25 and is discharged. The user holds the handle 23 and pushes it forward. The handle 23 drives the drag block 111 to move forward along the ground through the exhaust pipe 21, realizing the initial switching of the dust collection position. For ground with different flatness, the drive motor 112 drives the cleaning brush 114 to rotate and clean through the turntable 113. This allows the cleaning brush 114 to sweep the dust in the depressions of the ground with different flatness. The dust raised after sweeping is sucked into the dust collection cylinder 24 by the hose 223 for filtration and dust removal. The dust removal effect is good and the adaptability is strong. like Figure 1-5 As shown, in addition, for areas with a lot of dust, if the hose 223 cannot keep up with the dust during the cleaning process of the cleaning brush 114, causing dust to overflow from the receiving groove 1112, then stop pushing the drag block 111 forward and pull the handle 124 upward. The handle 124 drives the mounting base 121 to move upward through the push-pull rod 123. The mounting base 121 drives the drag block 111 to rotate around the hinge shaft 222 under the transition of the protrusion 116, so that the rotating roller 111 is separated from the ground and is only supported on the ground by the guide wheel 1162. At this time, the overflowing dust can be sucked into the dust collection cylinder 24 in time through the hose 223 and filtered by the dust filter screen 244, avoiding the secondary dust generated during the cleaning process from harming the health of the construction personnel and improving the dust removal efficiency. like Figure 6-7 As shown, when the dust in the dust collection cylinder 24 needs to be emptied and the dust filter 244 needs to be cleaned, pull out the pin at the upper opening of the dust collection cylinder 24, and then push the dust collection cylinder 24 downward along the guide rod 232 to separate the card holder 233 from the limiting groove 242, thus completing the disassembly of the dust collection cylinder 24. Subsequently, remove the dust filter 244 from the dust collection cylinder 24 for cleaning, and empty the dust in the dust collection cylinder 24. The cleaning work is convenient and quick.
