Description

Technical Field

[0001] The utility model relates to the technical field of construction dust reduction, in particular to a dust reduction device for engineering construction. Background Technique

[0002] If we want to reasonably control the construction site environment and use a dust reduction device to reasonably reduce dust in the construction environment, the construction site environment will be better purified, the air quality will be comprehensively improved, and naturally the air environment of the construction site will become healthier, which will provide good protection for the physical health of construction workers.

[0003] When using a dust reduction device for a large-scale construction site, a single dust reduction device can only reduce dust in one direction and cannot achieve a larger range of dust reduction effect. Often, multiple dust reduction devices need to be used, resulting in increased use of water and electricity, thus indirectly increasing the construction cost.

[0004] Moreover, during the use of the dust reduction device, there will be a certain degree of water accumulation at the bottom of the inner wall of the water spray nozzle. And as the atomized water is sprayed out, water droplets will also accumulate on the surface of the water spray nozzle. These water and water droplets will fall to the ground, resulting in the inability to be reused. When the dust reduction device is used for too long, the water falling to the ground will also increase, causing waste of water resources. Content of the Utility Model

[0005] The purpose of the utility model is to provide a dust reduction device for engineering construction to solve the problems raised in the above background technique.

Both sides of the rotating block are fixedly connected with connecting frames. One side of the surface of the connecting frame is threadedly connected with a fixing block. One side of the surface of the fixing block is fixedly connected with a sprayer assembly;

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figure 1-6As shown in the figure, a dust reduction device for engineering construction includes a vehicle frame 1. Inside the vehicle frame 1, a base 2 is installed. At the top of the base 2, a protective shell 3 is fixedly connected. Inside the protective shell 3, a swing mechanism 4 is installed. Under the action of the protective shell 3, it can prevent dust from contacting the internal parts of the swing mechanism 4 and causing a decrease in its operating efficiency. On one side of the swing mechanism 4, a rotating block 6 is installed. Under the action of the swing mechanism 4, it can drive the rotating block 6 to rotate. At the top of the base 2, a support rod 7 is fixedly connected. The support rod 7 is slidably connected to the inner wall of the rotating block 6. Under its action, it can assist in supporting the rotating block 6. On both sides of the rotating block 6, connecting frames 8 are fixedly connected. When the rotating block 6 rotates, it can drive the connecting frames 8 to move. The connecting frame 8 is composed of a fixed frame and a bolt. One side of the surface of the connecting frame 8 is slidably connected to the top of the base 2. On one side of the surface of the connecting frame 8, a fixing block 9 is threadedly connected. On one side of the surface of the fixing block 9, a sprayer assembly 10 is fixedly connected. Under the action of the connecting frame 8, the fixing block 9 can drive the sprayer assembly 10 to rotate. On one side of the surface of the sprayer assembly 10, a collecting shell 11 is fixedly connected. Under the action of the collecting shell 11, the accumulated water at the bottom of the inner wall of its water outlet and the water droplets condensed on its surface can be collected, preventing them from falling to the ground and causing waste of water resources. On one side of the collecting shell 11, a conveying mechanism 12 is installed. Inside the cavity of the base 2, a water storage tank 13 is installed. The collecting shell 11, the conveying mechanism 12, and the water storage tank 13 are used in cooperation. Under the action of the conveying mechanism 12, the water inside the collecting shell 11 can be conveyed to the inside of the water storage tank 13, enabling it to be reused. Inside the conveying mechanism 12, an installation frame 14 is provided. Inside the installation frame 14, a filter plate 15 is installed. The filter plate 15 and the conveying mechanism 12 are used in cooperation. Under the action of the filter plate 15, the collected water can be filtered to prevent dust and water from mixing during the collection process and causing blockage to the dust reduction mechanism during secondary use. On both sides of the conveying mechanism 12, fixing shells 16 are provided. Inside the cavity of the fixing shell 16, a limiting mechanism 17 is installed. The limiting mechanism 17 and the installation frame 14 are used in cooperation. Under its action, the installation frame 14 can be limited to prevent it from moving easily and reducing the filtering effect of the filter plate 15.

[0025] The swing mechanism 4 includes a stepper motor 41. One side of the surface of the stepper motor 41 is fixedly connected to the bottom of the inner wall of the protective shell 3. The output shaft of the stepper motor 41 is fixedly connected with a half gear 42. Under its action, the half gear 42 can be driven to rotate. A half tooth ring 44 is arranged inside the protective shell 3. The half tooth ring 44 is composed of a half tooth shell and 4 connecting rods. The connecting rod of the half tooth ring 44 is fixedly connected to the bottom of the half gear 42. The half gear 42 is located inside the half tooth ring 44. The number of its racks is equal, at the same horizontal plane but in opposite positions. When the half gear 42 rotates, the half tooth ring 44 can be driven to rotate. A timing gear 43 is meshed and connected to the surface of the half gear 42. The center of the bottom of the rotating block 6 penetrates through the top of the protective shell 3 and is rotationally connected to the penetrating part. The bottom of the rotating block 6 is fixedly connected to the top of the timing gear 43. Under the action of the rotating block 6, it can be prevented from falling, and when the timing gear 43 rotates, it can be driven to rotate. The half gear 42, the timing gear 43, and the half tooth ring 44 are used in cooperation. When the half gear 42 rotates to a suitable position, it meshes with one side of the timing gear 43 and drives it to rotate in the positive direction. When the half gear 42 continues to rotate and disengages from the surface of the timing gear 43, when the half tooth ring 44 rotates to a suitable position, it meshes with the other side of the timing gear 43 and drives it to rotate in the reverse direction. Repeating like this, the timing gear 43 can be driven to achieve reciprocating rotation. A positioning groove 5 is opened on the inner wall of the protective shell 3. The inner wall of the positioning groove 5 is slidably connected to the surface of the half tooth ring 44. Under the action of the positioning groove 5, it can be limited to prevent it from falling.

[0026] The conveying mechanism 12 includes a telescopic hose 121. The telescopic hose 121 is communicated with the collection shell 11. The other end of the telescopic hose 121 is communicated with an installation shell 122. The installation shell 122 is communicated with a water delivery pipe 123. The water delivery pipe 123 is communicated with the water storage tank 13. The inner wall of the installation shell 122 is slidably connected to the surface of the installation frame 14. The installation shell 122, the installation frame 14, and the filter plate 15 are used in cooperation. Under the action of the filter plate 15, the water entering the inside of the installation shell 122 can be filtered. When the collected water is reused, the telescopic hose 121 can convey the water inside the collection shell 11 to the installation shell 122, and the water delivery pipe 123 can convey the filtered water to the inside of the water storage tank 13. Under the operation of the dust reduction device, the water can be reused.

[0027] The limiting mechanism 17 includes a telescopic spring 171. One end of the telescopic spring 171 is fixedly connected to one side of the inner wall of the fixed shell 16, and the other end of the telescopic spring 171 is fixedly connected to a stopper 173. A stop rod 172 is fixedly connected to one side of the inner wall of the fixed shell 16. The stop rod 172 penetrates through the stopper 173 and is slidably connected to the penetration part. The stop rod 172 is located inside the telescopic spring 171. Under the action of the stop rod 172, the telescopic spring 171 can be prevented from generating a large displacement. The stopper 173 is L-shaped and is used in cooperation with the mounting bracket 14. The surface of the stopper 173 is slidably connected to the inner wall of the mounting bracket 14. Under the action of the stopper 173, the mounting bracket 14 can be limited to prevent it from moving easily. When the staff needs to clean and replace the filter plate 15, they pull the two side stoppers 173. The stoppers 173 drive the telescopic spring 171 to extend. When the stoppers 173 are moved out of the mounting bracket 14 and the stoppers 173 are rotated, the staff slows down the pulling force. Under the action of the telescopic spring 171, the stoppers 173 can be driven to move back. When the stoppers 173 move to one side of the mounting shell 122, they can be limited by the mounting shell 122. The staff can pull the pull rod on one side of the mounting bracket 14 to take it out, improving the replacement efficiency.

[0028] It should be noted that: technical features such as the sprayer assembly 10 proposed in this technical solution should be regarded as prior art. For the specific structures, working principles, possible control methods, and spatial arrangement methods of these technical features, conventional selections in this field can be adopted, and this technical solution will not be further specifically elaborated.

[0029] Working principle: The staff turns on the stepper motor 41. The stepper motor 41 drives the half gear 42 to rotate. When the half gear 42 rotates, it makes the half tooth ring 44 rotate. When the half gear 42 rotates to a suitable position, it meshes with one side of the timing gear 43 and drives it to rotate in the positive timing direction. The half gear 42 continues to rotate and disengages from the surface of the timing gear 43. When the half tooth ring 44 rotates to a suitable position, it meshes with the other side of the timing gear 43 and drives it to rotate in the reverse direction, so that the timing gear 43 rotates reciprocally. Under the action of the timing gear 43, the rotating block 6 rotates reciprocally. The rotation of the rotating block 6 drives the connecting frame 8 to rotate. When the connecting frame 8 rotates, it drives the sprayer assembly 10 to swing reciprocally through the fixed block 9, increasing the dust reduction range of the dust reduction device. During the use of the dust reduction device, the water accumulated at the bottom of the inner wall of its water outlet and the water droplets condensed on its surface fall into the collection shell 11. Under the action of the telescopic hose 121, the water inside it flows into the mounting shell 122. The water delivery pipe 123 can deliver the filtered water to the inside of the water storage tank 13, thus reducing the waste of water resources.

Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
