Description

Technical Field

[0001] This utility model relates to the field of municipal construction technology, specifically to a dust suppression spraying device for municipal construction. Background Technology

[0002] Municipal engineering refers to urban public works projects such as urban roads, bridges, water supply and drainage, sewage treatment, urban flood control, landscaping, road greening, streetlights, and environmental sanitation. Dust pollution is a very common problem during the construction of municipal engineering projects. In order to reduce the impact of dust on the surrounding environment, dust suppression spraying equipment is used to spray water mist on the construction site. The nozzle position of existing dust suppression spraying equipment is generally fixed, which limits the coverage area of ​​the sprayed atomized liquid. When the construction area is large, multiple spraying equipment often need to work at the same time. There are also equipment that can increase the coverage by swinging the nozzle, but the swing amplitude is generally fixed and the spraying range cannot be adjusted. When the spraying range is too large, it is easy to wet the construction personnel, resulting in poor performance. Utility Model Content

Detailed Implementation

[0019] 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.

[0020] Please see Figure 1-3 This embodiment provides a technical solution: a dust suppression spraying device for municipal construction, including a support shell 1 and a control unit 8;

[0021] Support shell 1: A rotating frame 2 is rotatably connected to the left end of its upper surface. The support shell 1 is installed on a municipal construction vehicle and moved to the municipal construction site. The upper end of the rotating frame 2 is equipped with evenly distributed nozzles 5. The rotating frame 2 drives the nozzles 5 to swing through the support cylinder 3 and the annular tube 4, thereby creating a fan-shaped spray and increasing the spraying range. The lower end of the rotating frame 2 is equipped with a gear 7. The right side of the support shell 1 is equipped with a control switch group 11, the input end of which is electrically connected to an external power source. The upper end of the rotating frame 2 is equipped with a support cylinder 3, which contains a fan to blow air and increase the travel distance of the droplets. The left end of the support cylinder 3 is provided with an annular pipe 4, and the left end of the nozzle 5 is fixedly connected to the water outlet on the right side of the annular pipe 4. The support shell 1 is provided with a water pump 6. The water outlet pipe of the water pump 6 is connected to the liquid inlet end of the outer arc surface of the annular pipe 4. The liquid inlet end of the water pump 6 is connected to a clean water source. The input end of the water pump 6 is electrically connected to the output end of the control switch group 11. By adjusting the control switch group 11, the water pump 6 works and supplies water to the inside of the annular pipe 4. Then the water flow is sprayed out from the left end of the nozzle 5. The water mist particles diffuse in the air and come into contact with the dust particles. They will collide and adhere to each other, so that a layer of water film is attached to the surface of the dust particles. Due to the increase in mass, the dust particles with the water film attached cannot continue to be suspended in the air and gradually settle down, thus achieving the dust suppression effect.

[0022] Control unit 8: It includes a support shaft 81, a second gear 82, a lever arm 83, and a drive assembly 84. The support shaft 81 is rotatably connected to the middle of the support housing 1. The lower end of the support shaft 81 is provided with a second gear 82, which meshes with a first gear 7. The number of teeth of the second gear 82 is greater than the number of teeth of the first gear 7, which can amplify the swing angle. The lever arm 83 is provided in the middle of the outer arc surface of the support shaft 81. The drive assembly 84 is used to drive the reciprocating swing of the lever arm 83. The lever arm 83 reciprocates around the support shaft 81, and the support shaft 81 drives the second gear 82 to rotate reciprocally. The second gear 82 is connected to the first gear... 7 drives the rotating frame 2 to reciprocate. The control unit 8 also includes a lead screw 85, which is threaded to the upper surface of the support shell 1. The left end of the lead screw 85 is rotatably connected to the drive assembly 84. The drive assembly 84 includes a movable seat 841, a rotating disk 842, a round shaft 843, and a motor 844. The movable seat 841 is slidably connected to the middle of the upper surface of the support shell 1. The right end of the movable seat 841 is rotatably connected to the left end of the lead screw 85. The rotating disk 842 is rotatably connected to the middle of the movable seat 841. The round shaft 843 is provided at the edge of the lower surface of the rotating disk 842. The round shaft 843 is connected to the lever arm 8. The long sliding hole in the middle of the 3rd section is slidably connected. A motor 844 is mounted on the upper surface of the moving base 841. The output shaft of the motor 844 is fixedly connected to the upper end of the rotating disk 842. The input end of the motor 844 is electrically connected to the output end of the control switch group 11. When the motor 844 operates, its output shaft drives the rotating disk 842 to rotate. The rotation of the circular shaft 843 on the lower surface of the rotating disk 842 causes the axis of the circular shaft 843 to not coincide with the axis of the rotating disk 842, resulting in longitudinal and lateral movement of the circular shaft 843. The circular shaft 843 slides relative to the long sliding hole in the lateral direction of the lever arm 83. The lead screw 85... A handwheel 9 is provided on the right end. Rotating the lead screw 85 via the handwheel 9 will cause the lead screw 85 to drive the rotating disk 842 and the motor 844 to move laterally via the movable seat 841. This allows adjustment of the distance between the rotating disk 842 and the support shaft 81. The greater the distance between the rotating disk 842 and the round shaft 843 and the support shaft 81, the smaller the rotation range of the drive lever 83. This allows adjustment of the spraying range according to usage requirements. A protective shell 10 is provided on the upper surface of the support shell 1. The movable seat 841 and the motor 844 are both located inside the protective shell 10, which provides protection for the internal components.

[0023] The working principle of the dust suppression spraying device for municipal construction provided by this utility model is as follows: During use, the support shell 1 is installed on the municipal construction vehicle, and the support shell 1 is moved to the construction site. The inlet end of the water pump 6 is connected to a clean water source. During construction, the control switch group 11 is adjusted, and the water pump 6 operates, supplying water to the inside of the annular pipe 4. Then, the water flow is sprayed from the left end of the nozzle 5. The water mist particles diffuse in the air and come into contact with the dust particles. Collisions and adhesion occur between them, causing a water film to adhere to the surface of the dust particles. Due to the increased mass, the dust particles with the water film cannot continue to remain suspended in the air and gradually settle down, thus achieving the dust suppression effect. When the construction area is large and the spraying area is small, the control switch group 11 can be adjusted to operate the motor 844. The output shaft of the motor 844 drives the rotating disk 842 to rotate. The rotation of the circular shaft 843 on the lower surface of the rotating disk 842 causes the circular shaft 843 to rotate. The axis of the rotating disk 842 does not coincide with the axis of the rotating disk 842, resulting in longitudinal and lateral movement of the circular shaft 843. The circular shaft 843 slides relative to the lateral sliding hole of the lever arm 83, simultaneously driving the lever arm 83 to reciprocate around the support shaft 81. The support shaft 81 drives the gear 2 to rotate reciprocally. The gear 2, through the gear 7, drives the rotating frame 2 to reciprocate. The rotating frame 2, through the support cylinder 3 and the annular tube 4, drives the nozzle 5 to swing, thus creating a fan-shaped spray and increasing the spraying range. During use, the screw 85 can be rotated via the handwheel 9. The screw 85, through the moving seat 841, drives the rotating disk 842 and the motor 844 to move laterally, thereby adjusting the distance between the rotating disk 842 and the support shaft 81. The greater the distance between the rotating disk 842 and the circular shaft 843 and the support shaft 81, the smaller the rotation range of the lever arm 83, allowing adjustment of the spraying range according to usage requirements.

[0024] It is worth noting that the motor 844 and water pump 6 disclosed in the above embodiments can be freely configured according to the actual application scenario. The motor 844 can be a geared motor with model number 5IK120RGU-CF, and the water pump 6 can be a diaphragm pump with model number DP-130. The control switch group 11 is equipped with switch buttons corresponding to the motor 844 and the water pump 6 to control their switching operation.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
