Description

Technical Field

[0001] This utility model relates to the field of road construction equipment technology, and in particular to a dust suppression device for road construction. Background Technology

[0002] Dust pollution has always been a significant factor affecting the construction environment and surrounding air quality during road construction. While traditional water trucks can help reduce dust to some extent, their nozzles are usually fixed and cannot be adjusted in terms of spray range and direction, resulting in limited dust reduction effectiveness. This is especially true under different road conditions and construction needs, as they cannot flexibly and effectively control dust, making it difficult to meet the diverse dust control requirements of road construction.

[0003] Chinese invention patent CN108086230A discloses a road dust suppression water sprinkler truck, including a chassis. A water sprinkler device is fixedly installed on the upper side of one end of the chassis. A water tank is fixedly installed on one side of the water sprinkler device. A water inlet button is fixedly installed on the upper side of the water tank. A water outlet is opened on the lower side of the water tank. A dust collection box is fixedly installed on one side of the water tank. A vortex fan is fixedly installed on the lower side of the dust collection box. A dust collection plate is fixedly installed next to the vortex fan. A small hydraulic pump station is fixedly installed on one side of the dust collection box and the vortex fan. This invention discloses a road dust suppression water sprinkler truck that pre-treats dust on the road surface through a vortex fan located at the front, thereby avoiding splashing mud and water during the water sprinkler truck's operation. Furthermore, the water sprinkler system of the truck is synchronized with the movement of the wheels, avoiding water waste while waiting at red lights.

[0004] However, in this solution, the water spraying device is fixed, and the spraying angle and range are constant, making it impossible to make adaptive adjustments according to actual needs and difficult to adapt to different road construction scenarios. Utility Model Content

[0005] To address the shortcomings in the aforementioned background technology, this utility model proposes a dust suppression and water spraying device for road construction, which solves the problem that the existing technology has a constant spraying angle and range, making it difficult to adapt to different construction watering scenarios.

[0006] The technical solution of this utility model is implemented as follows: A dust suppression and water spraying device for road construction includes a sprinkler truck body. A sprinkler tank is fixedly installed on the sprinkler truck body. A high-pressure pump is connected to the output end of the sprinkler tank. A plurality of nozzles are connected to the output end of the high-pressure pump. A swing assembly is installed on the sprinkler truck body. The swing assembly is connected to a crossbar and is used to drive the crossbar to swing. The nozzles are installed on the crossbar. By driving the crossbar to swing through the swing assembly, the nozzles are driven to swing, thereby adjusting the spray range and direction, effectively solving the problem of fixed nozzles in existing sprinkler trucks and improving the dust suppression effect.

[0007] Preferably, the swing assembly includes support frames fixedly mounted on both sides of the sprinkler truck. A fixed seat is fixedly mounted on each support frame, and a swing rod is rotatably mounted on the fixed seat. An electric push rod is rotatably connected to the middle of the swing rod, and the electric push rod is hinged to the support frame. The swing rod is fixedly connected to the end of the crossbar. When the electric push rod extends or retracts, it drives the swing rod to rotate on the fixed seat, thereby driving the crossbar to swing. The structure is simple, reliable, and easy to control, enabling precise adjustment of the nozzle swing angle to adapt to different dust suppression needs.

[0008] Preferably, the high-pressure pump is connected to a delivery pipe with several evenly distributed interfaces, each connected to a nozzle via a flexible hose. Several fixing rings are equidistantly arranged on the crossbar, each fixing ring having a threaded bolt on one side. The nozzle is mounted on the fixing ring and locked in place by the fixing bolt, facilitating nozzle installation and removal. The support frame is an L-shaped support frame. The L-shaped support frame effectively supports the weight of the swing assembly and the crossbar.

[0009] Preferably, a solenoid valve is installed on the delivery pipe. A drain pipe is connected to the delivery pipe between the output end of the high-pressure pump and the solenoid valve, and a valve is installed on the drain pipe. Impurities and sediments in the delivery pipe can be periodically discharged through the drain pipe and valve to prevent clogging of the nozzles and ensure the normal operation of the equipment.

[0010] Preferably, the water tank has a water tank opening at its top, and a water tank cover is hinged to one side of the water tank opening. A limiting groove is equidistantly spaced in a ring inside the water tank opening, and a filter screen engages within the limiting groove. The filter screen can perform preliminary filtration of the added water, intercepting large particles of impurities, protecting the high-pressure pump and spray nozzles, and extending their service life.

[0011] Preferably, the filter screen has uniformly spaced filter holes inside, and a limit block is provided on the outer ring of the filter screen corresponding to the position of the limit groove. A filter is provided at the inlet end of the high-pressure pump. The filter can further filter impurities in the water, preventing impurities from entering the high-pressure pump and causing equipment damage or affecting the spraying effect of the nozzles, thus improving the reliability and stability of the entire device.

[0012] The beneficial effects of this utility model are: By setting up a swing component to drive the crossbar to swing, which in turn drives the nozzle to swing, the problem of fixed and unadjustable nozzles in existing sprinkler trucks is effectively solved. This allows for flexible adjustment of the nozzle's spray range and direction based on actual road construction conditions and dust distribution, achieving more precise and efficient dust suppression. This significantly improves dust suppression effectiveness, adapts to the needs of different road construction scenarios, and provides strong support for dust control in road construction environments. Furthermore, the water tank opening at the top of the sprinkler tank facilitates water filling, and the internal filter screen performs preliminary filtration of the added water, intercepting large particles of impurities. The filter at the high-pressure pump inlet further filters impurities in the water. This double-layer filtration effectively protects critical equipment such as the high-pressure pump and nozzles, preventing impurities from entering and causing damage or blockage, ensuring the spraying effect of the nozzles. The installation of a drain pipe and valves facilitates the regular discharge of impurities and sediment from the delivery pipe, ensuring the normal operation of the equipment and reducing maintenance costs and equipment failure rates.

Detailed Implementation

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

[0016] like Figure 1 , 2 As shown in Embodiment 1, a dust suppression device for road construction includes a water truck body 110, on which a water tank 111 is fixedly mounted. A high-pressure pump 125 is connected to the output end of the water tank 111, and a plurality of nozzles 121 are connected to the output end of the high-pressure pump 125. A swing assembly 300 is mounted on the water truck body 110, connected to a crossbar 120 and used to drive the crossbar 120 to swing. The nozzles 121 are mounted on the crossbar 120. In actual use, by using the swing assembly to drive the crossbar to swing, which in turn drives the nozzles to swing, the problem of fixed and unadjustable nozzles in existing water trucks is effectively solved. The device allows for flexible adjustment of the spray range and direction of the nozzles according to the actual road construction conditions and dust distribution, achieving more precise and efficient dust suppression operations. This significantly improves the dust suppression effect, adapts to the needs of different road construction scenarios, and provides strong support for dust control in road construction environments.

[0017] Example 2: A dust suppression and water spraying device for road construction, based on Example 1, such as... Figure 4 As shown, the swing assembly 300 includes support frames 310 fixedly mounted on both sides of the sprinkler truck. A fixed seat 311 is fixedly mounted on the support frame 310, and a swing rod 312 is rotatably mounted on the fixed seat 311. An electric push rod 313 is rotatably connected to the middle of the swing rod 312. The electric push rod 313 is hinged to the support frame 310, and the swing rod 312 is fixedly connected to the end of the crossbar 120. Through the extension and retraction of the electric push rod 313, the swing rod 312 swings on the fixed seat 311, thereby realizing the left and right swing of the crossbar 120, and thus flexibly adjusting the spray range and direction of the nozzle 121.

[0018] Specifically, in this embodiment, the support frame 310 adopts an L-shaped support frame, which provides stable support for the swing assembly 300 and the crossbar 120, ensuring the stability of the device during operation. By manually or automatically controlling the extension and retraction of the electric push rod 313, the swing rod 312 drives the crossbar 120 to swing, thereby adjusting the spray range and orientation of the nozzle 121 to achieve the best dust suppression effect.

[0019] Example 3: A dust suppression and water spraying device for road construction, based on Example 2, such as... Figure 5 As shown, the high-pressure pump 125 is connected to a delivery pipe 123, which has several evenly distributed interfaces. These interfaces are connected to the nozzle 121 via flexible hoses 122. A number of fixing rings 130 are equidistantly arranged on the crossbar 120. In this embodiment, the fixing rings 130 are metal rings, the crossbar is a metal rod, and the fixing rings are welded and fixedly mounted on the crossbar, with the axis of the fixing rings perpendicular to the axis of the crossbar. A fixing bolt 131 is threaded onto one side of the fixing ring 130. The nozzle 121 is mounted on the fixing ring 130 and locked in place by the fixing bolt 131. The fixing bolt 131 secures the nozzle 121 through rotational friction. This connection method not only facilitates the installation and removal of the nozzle 121 but also allows adjustment of the position and angle of the nozzle 121 on the crossbar 120 according to actual needs.

[0020] As a further specific implementation, a solenoid valve 124 is installed on the delivery pipe 123 to realize automatic control of water flow. A drain pipe 126 is connected to the delivery pipe 123 between the output end of the high-pressure pump 125 and the solenoid valve 124. A valve 127 is installed on the drain pipe 126 to facilitate the periodic discharge of impurities and sediments in the delivery pipe 123 and prevent clogging of the nozzle 121.

[0021] Example 4: A dust suppression and water spraying device for road construction, based on Example 3, such as... Figure 3 , 4 As shown, the water tank 111 has a water tank opening 113 at its top, and a water tank cover 112 is hinged to one side of the water tank opening 113. A limiting groove 114 is equidistantly spaced in a ring inside the water tank opening 113. A filter screen 115 is engaged inside the limiting groove 114. The filter screen 115 has uniformly spaced filter holes, and a limiting block 116 is provided on the outer ring of the filter screen 115 corresponding to the position of the limiting groove 114. When water is added to the water tank 111 through the water tank opening 113, the filter screen 115 can perform preliminary filtration of the added water when the water tank is connected to the municipal water pipe, intercepting large particles of impurities. This prevents foreign objects and impurities from entering the water tank 111 body when replenishing the water supply, reducing blockage and damage to the pump body and pipes, and protecting equipment such as the high-pressure pump 125 and the spray nozzle 121. The setting of limiting groove and limiting block enables quick snap-fit ​​installation of filter screen, making filter screen 115 easy to install, disassemble, clean and replace.

[0022] As a further specific implementation, a filter is provided at the inlet end of the high-pressure pump 125 to further filter impurities in the water, preventing impurities from entering the high-pressure pump 125 and causing equipment damage or affecting the spraying effect of the nozzle 121. In this embodiment, a conventional Y-type filter can be selected, which has the characteristics of simple structure, low resistance, and convenient sewage discharge. It can effectively remove impurities in the medium, protect the normal use of the equipment, adapt to the limited installation environment in the water spraying dust suppression device, and can perform a final filtration of the water in the water tank to prevent impurities from entering the high-pressure pump.

[0023] In actual road construction dust suppression operations, operators can first inject water into the sprinkler tank 111 through the water tank inlet 113. After preliminary filtration by the filter screen 115, the water enters the sprinkler tank 111. The high-pressure pump 125 is then started, drawing water from the sprinkler tank 111. After further filtration by the filter, the water is delivered to each nozzle 121 through the delivery pipe 123. According to actual dust suppression needs, the opening and closing of the solenoid valve 124 is controlled to achieve water flow control for the corresponding nozzle 121. The valve 127 is periodically opened to discharge impurities and sediments from the delivery pipe 123 through the drain pipe 126, ensuring the normal operation of the equipment.

[0024] As a further optional solution, the main control room inside the sprinkler truck body 110 has a control panel that can operate the solenoid valve 124, high-pressure pump 125, and electric push rod 313, etc., with specific connections made via wires. The solenoid valve 124 mainly controls the water flow through the delivery pipe 123, enabling precise water usage control and water conservation. The drain pipe 126, in conjunction with the valve 127, is mainly used to promptly clean and drain the accumulated water inside the sprinkler tank 111. Alternatively, filtration can be achieved by adding a filter sponge core at the inlet of the high-pressure pump 125.

[0025] The dust suppression sprinkler system for road construction in this embodiment uses a swing assembly to drive the nozzles to swing, enabling flexible adjustment of the nozzle spray range and direction. This effectively solves the problem of fixed nozzles on existing sprinkler trucks and improves dust suppression efficiency. Furthermore, its simple and reasonable structure makes it easy to operate and maintain, and its strong adaptability allows it to meet the dust suppression needs of different road construction scenarios, providing a strong guarantee for improving the road construction environment.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
