Description

Technical Field

[0001] This invention relates to the field of construction engineering technology, and in particular to a dust suppression spray device for construction engineering. Background Technology

[0002] During the construction process, a large amount of dust is generated from earthwork excavation, material transportation, and mechanical operations. This dust not only seriously pollutes the construction environment and affects the health of construction workers, but may also spread to surrounding areas, causing environmental complaints and even violating relevant environmental protection standards. Therefore, dust suppression spray devices are commonly used on construction sites to suppress dust in the air, thereby improving the working environment and reducing dust spread.

[0003] In practice, some problems still exist: Existing dust suppression spraying devices mainly use nozzles to evenly spray water mist onto the construction area to achieve dust reduction. However, in actual use, existing spraying devices still have many shortcomings. On the one hand, the water sources commonly used at construction sites generally have many impurities and poor water quality, which can easily cause nozzle blockage and affect the spraying effect. On the other hand, most of the nozzles in existing devices have a fixed direction and cannot automatically adjust the spraying direction or coverage area according to the actual working conditions, resulting in blind spots and low dust reduction efficiency. At the same time, some devices lack efficient filtration and cleaning mechanisms. Once the filter is blocked by impurities, it needs to be manually disassembled and cleaned, which increases the maintenance frequency and labor costs and affects the continuity of construction. Summary of the Invention

[0004] (a) Technical problems to be solved To address the aforementioned problems in the prior art, this invention provides a dust suppression spray device for construction engineering, which solves the problems of easy nozzle clogging, non-adjustable direction, inconvenient cleaning, and impact on spraying effect and construction efficiency.

[0005] (II) Technical Solution To achieve the above objectives, the main technical solution adopted by the present invention is as follows: A dust suppression spray device for construction engineering includes a dust suppression spray device body, an adaptive filtration mechanism on one side of the dust suppression spray device body, and an adjustment mechanism on the outside of the dust suppression spray device. An adaptive filtration mechanism includes an output shaft, supports, return springs, push plates, and anti-clogging brushes. The middle part of the output shaft is fixedly connected to two supports, the inner sides of the two supports are fixedly connected to two return springs, one end of each of the two return springs is fixedly connected to the inner side of the push plate, and the inner sides of the two push plates are fixedly connected to the inner sides of the two anti-clogging brushes. An adjustment mechanism is provided, comprising a transmission component, a crank, and a mounting base. One end of the transmission component is rotatably connected to one end of the crank, and the other end of the crank is fixedly connected to the outer side of the transmission component.

[0006] The dust suppression spray device has a spray pipe rotatably connected to the inner side of its main body, a nozzle fixedly connected to the outer wall of the spray pipe, and a connecting pipe fixedly connected to one end of the spray pipe.

[0007] A transfer pump is provided on one side of the dust-proof spray device body. The water outlet of the transfer pump is fixedly connected to one end of the connecting pipe, and a filter pipe is fixedly connected to the water inlet of the transfer pump.

[0008] Two drive wheels are rotatably connected to the top of the filter tube, and a drive belt is sleeved between the two drive wheels. A drive rod is fixedly connected to the bottom of one of the drive wheels, and a drive blade is fixedly connected to the bottom of the drive rod.

[0009] The drive blade is rotatably connected to the inner wall of the filter tube. A collar is engaged with the inner wall of the filter tube. A filter screen is fixedly connected to the inner wall of the collar. A connecting plate is fixedly connected to the middle of the collar. The middle of the connecting plate is rotatably connected to the output shaft.

[0010] A fixing rod is fixedly connected to one side of the inner wall of the filter tube, and a first bevel gear is fixedly connected to the inner side of the fixing rod. A second bevel gear is engaged at the top of the first bevel gear.

[0011] One of the transmission wheels has a connecting rod fixedly connected to its bottom end. The bottom end of the connecting rod penetrates the outer wall of the filter tube and is fixedly connected to the top end of the second bevel gear. The inner side of the anti-clogging brush is attached to the outer wall of the filter screen.

[0012] A scraper is fixedly connected to the outer side of the support, and a limit rod is fixedly connected to the bottom end of the scraper. One end of the limit rod is fixedly connected to the outer side of the scraper, and the inner side of the first bevel gear is fixedly connected to one end of the output shaft.

[0013] The other end of the output shaft is rotatably connected to a second fixing rod. The top end of the second fixing rod is fixedly connected to the inner wall of the top end of the filter tube, and the push plate is slidably connected to the outer wall of the connecting plate.

[0014] A motor base is fixedly connected to one side of the dust suppression spray device body, an output rod is fixedly connected to the output end of the motor base, the output rod is fixedly connected to the outer wall of the transmission component, and the mounting base is fixedly connected to the spray pipe.

[0015] (III) Beneficial Effects The beneficial effects of this invention are: In this invention, by setting an adaptive filtration mechanism, dynamic filtration and synchronous self-cleaning can be achieved before the construction water enters the spray system. This mechanism adopts a structure in which the output shaft drives the filter screen to rotate. Combined with the elastic contact cleaning design of the anti-clogging brush and scraper, the filtration process can operate continuously without relying on external electronic control. During the rotation, it effectively removes particulate impurities attached to the filter screen and deposits on the inner wall of the filter tube. The power conversion is completed by the water flow driven transmission blade and transmission components. The water flow energy is converted into the rotational power of the filter components through the bevel gear set, and a self-circulation mechanism of water flow activation-power linkage-impurity removal is constructed. This effectively solves the problems of easy clogging, difficult cleaning, and frequent maintenance of traditional static filtration devices. At the same time, the limit rod controls the movement range of the scraper to prevent interference and improve the reliability of the system structure. This design not only improves the filtration efficiency and operational stability and extends the working cycle of the filter element, but also significantly reduces the need for manual maintenance and improves the automation of the device and its ability to adapt to complex construction environments. In this invention, an adjustment mechanism enables real-time dynamic control of the nozzle direction and spray angle based on dust distribution and spraying requirements at the work site. The adjustment mechanism consists of a motor base, transmission components, a crank, and a mounting base. The motor base drives the transmission components to move in a circular or reciprocating motion, thereby driving the crank to adjust the rotation or elevation angle of the spray pipe, achieving precise spray direction control. Multiple nozzles are evenly distributed on the outer wall of the spray pipe, which is supplied with water via a connecting pipe and a transmission pump. During rotational adjustment, the water path remains continuous and stable, preventing water pressure fluctuations or nozzle blockage caused by angle adjustment. The mounting base is tightly connected to the spray pipe, ensuring adjustment accuracy and transmission consistency. This mechanism is compact, responsive, and not prone to jamming, adapting to multi-angle work scenarios. It is particularly suitable for construction sites with high dust levels and complex terrain, effectively improving spray coverage and dust suppression, and enhancing the overall construction adaptability and intelligent control level of the device.

In actual implementation, the spray pipe 2 can be angled through the rotating connector at its bottom, and the nozzle 3 is connected to the connecting pipe 4 to form a stable water channel structure.

In actual implementation, the construction water source impacts the drive blade 704 from the bottom, pushing the drive rod 703 to rotate.

[0028] Optionally, a motor base 801 is fixedly connected to one side of the dust suppression spray device body 1, an output rod 805 is fixedly connected to the output end of the motor base 801, the output rod 805 is fixedly connected to the outer wall of the transmission component 804, and the mounting base 802 is fixedly connected to the spray pipe 2.

[0029] Working Principle: This system achieves efficient filtration and automatic cleaning of impurities in the construction water source, effectively ensuring the smooth operation and stability of the subsequent spraying system. The filtration mechanism mainly includes an output shaft 712, a support 714, a return spring 717, a push plate 715, an anti-clogging brush 718, and a scraper 708, and operates in conjunction with a power transmission structure located at the top of the filter pipe 6. It features the advantages of continuous operation without manual intervention. During operation, construction water enters the inner cavity of the filter pipe 6 through the inlet of the transfer pump 5 and undergoes primary impurity interception through the built-in filter screen 707. The filter screen 707 is located on the inner wall of a collar 706 within the filter pipe 6. A connecting plate 719 is fixedly connected to the middle of the collar 706, and the connecting plate 719 is rotatably connected to the output shaft 712. When the water flow impacts the drive blade 704 at the bottom of the filter pipe 6, the drive blade 704 rotates accordingly. The transmission rod 703 drives the transmission wheel 702 upwards, which in turn drives one of the transmission wheels 702 to rotate. This transmission wheel 702 transmits power to the other transmission wheel 702 via the transmission belt 701, achieving double-wheel linkage. The bottom end of the second transmission wheel 702 is fixed to the second bevel gear 711 via the connecting rod 709. The second bevel gear 711 meshes with the first bevel gear 710, turning the rotational power vertically to the output shaft 712, thereby driving the output shaft 712 to rotate along its axis. When the output shaft 712 rotates, it drives the connecting plate 719 and the collar 706 to rotate as a whole, which in turn drives the filter screen 707 to rotate around the central axis, achieving dynamic filtration. At the same time, two supports 714 are located on the output shaft 71. 2. At the center of both sides, for axial stability, a return spring 717 is connected to the inner side of the support 714. One end of the return spring 717 is connected to the push plate 715, and the other side of the push plate 715 is fixed with an anti-clogging brush 718. The anti-clogging brush 718 is always in close contact with the outer surface of the filter screen 707 under the elastic force of the spring, and continuously cleans the particulate impurities attached to the surface of the filter screen 707 during the rotation of the filter screen 707, so as to achieve synchronous cleaning and prevent the filter screen 707 from clogging due to the accumulation of impurities. It is worth noting that a scraper 708 is also fixed on the outer side of the support 714. The bottom end of the scraper 708 is connected to the inner wall of the device through the limiting rod 713. When the output shaft 712 rotates and drives the filter assembly to rotate, the scraper 708 is in contact with the outer ring of the filter screen 707 and the filter tube 6. The annular space between the inner walls assists in the friction cleaning of the inner wall of the filter tube 6, preventing large particles or deposits from accumulating in this area, thereby effectively extending the operating cycle of the filter screen 707. The limiting rod 713 structure is used to control the range of motion of the scraper 708, preventing it from deviating from the cleaning area or interfering with other rotating components. Through the above structural design and transmission coordination, this device can dynamically filter the water source before spraying operations. During the filtration process, the anti-clogging brush 718 and the scraper 708 can be automatically cleaned simultaneously, significantly reducing the frequency of nozzle clogging, extending the equipment maintenance cycle, and improving the degree of automation. It has significant beneficial effects such as compact structure, stable operation, strong adaptability, and simple maintenance, and is further enhanced by the setting of the adjustment mechanism 8.To achieve dynamic control of the spray direction and spray force, the adjustment mechanism 8 includes a transmission component 804, a crank 803, and a mounting base 802. One end of the transmission component 804 is rotatably connected to the crank 803, and the other end is fixedly connected to the output rod 805 of the motor base 801. When the motor base 801 starts, it drives the output rod 805 to rotate, thereby driving the transmission component 804 to perform circular or reciprocating motion, causing the crank 803 to move, ultimately achieving fine adjustment of the angle or direction of the nozzle 2. The nozzle 2 body is rotatably connected to the inside of the device body, and multiple nozzles 3 are fixedly installed on its outer wall. It is connected to the transmission pump 5 through a connecting pipe 4 for water supply. In actual operation, the adjustment mechanism 8 controlled by the motor base 801... The nozzle 3 can be adaptively adjusted in direction according to the dust distribution or working angle requirements at the construction site, effectively improving the spray coverage and dust suppression accuracy. The mounting base 802 is fixedly connected to the spray pipe 2, ensuring precise transmission of adjustment actions. The rotation of the spray pipe 2 will not affect the smooth water supply of its connecting pipe 4. At the same time, this structure has good structural stability and transmission coordination, and is not prone to jamming. In addition, with the front-end adaptive filtration mechanism 7 and the linkage anti-clogging system, it can realize the three-in-one linkage operation of water source filtration, anti-clogging cleaning, and direction adjustment during spraying operations, improving the overall intelligence level and construction adaptability of the device, and is particularly suitable for construction sites with high dust and complex terrain.
