Technical Field

[0001] This utility model relates to the technical field of construction environmental protection equipment, specifically to a dust suppression device for construction site use. Background Technology

[0002] Dust particles are easily generated during activities such as building construction, road and pipeline construction, building demolition, material transportation, material storage, and road cleaning, which can pollute the atmosphere. In particular, construction sites may be dusty, and construction workers who work in such environments for long periods of time will inhale a lot of dust, which will affect their health.

[0003] However, traditional dust suppression equipment suffers from a fixed spray range and blind spots due to the inconvenience of nozzle angle adjustment. Therefore, those skilled in the art have developed a dust suppression device for construction sites to address the problems mentioned in the background section. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A dust suppression device for construction site use includes a trailer platform, a storage tank for storing water is installed at the top of the trailer platform, a spraying mechanism for spraying water mist is installed at the top of the storage tank, and a drive mechanism for driving the storage tank is installed on one side of the top of the trailer platform.

[0006] Preferably, the spraying mechanism includes two sets of support plates, and a spray cannon for spraying atomized water is rotatably mounted between one set of support plates. One end of the spray cannon is connected to the bottom of the storage tank.

[0007] Preferably, a limiting plate is fixedly installed on both sets of support plates, and a first limiting rod is fixedly installed at both ends on one side of the spray cannon. A first limiting groove is opened on both limiting plates, and the two first limiting rods are respectively movably installed in the two first limiting grooves.

[0008] Preferably, both ends of one side of the limiting plate are fixedly installed with fixing plates, and both sides between the two fixing plates are rotatably installed with lead screws. One end of each of the two lead screws is driven by a first motor. Both first motors are fixedly installed on the top of a fixing plate, and adjusting plates are threaded onto the two lead screws.

[0009] Preferably, one end of each of the two adjusting plates is provided with a limiting hole, and one side of each of the two first limiting rods is movably disposed in the two limiting holes, and both ends of each of the two fixing plates are equipped with a first switch for adjusting the rotation direction of the first motor.

[0010] Preferably, the drive mechanism includes a mounting bracket and an arc-shaped rack. A second motor is fixedly mounted on the mounting bracket, and a drive gear is fixedly mounted on the output shaft of the second motor. The drive gear and the arc-shaped rack are meshed together.

[0011] Preferably, the arc-shaped rack is fixedly connected to one side of the storage tank, and connecting plates are fixedly installed on both sides of the top of the trailer plate. A second switch for driving the second motor to rotate in the opposite direction is installed on one end of each of the two connecting plates.

[0012] Preferably, a second limiting groove is provided on both sides of the top of the trailer plate, and a second limiting rod is movably installed in each of the two second limiting grooves, and the top of each of the two second limiting rods is fixedly connected to the bottom of the storage tank.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The spraying and driving mechanisms facilitate the rotation of the lead screw driven by the first motor, thereby driving the adjusting plate to move between the two fixed plates. The limiting hole and the first limiting groove enable the first limiting rod to move in an arc shape, thereby driving one end of the spray cannon to rotate on the two support plates. The second motor drives the drive gear to rotate, thereby causing the meshing arc rack to rotate. The two second limiting rods move within the two second limiting grooves, thereby causing the storage tank to rotate. This, in turn, drives the spray cannon located at the top of the storage tank to rotate laterally. Combined with the rotation direction driven by the first motor, the spray range of the spray cannon can be increased. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to embodiments:

[0021] This utility model discloses a dust suppression device for construction site use. (Refer to...) Figure 1-4 It includes a trailer platform 1, a storage tank 2 for storing water is installed on the top of the trailer platform 1, a spraying mechanism for spraying water mist is installed on the top of the storage tank 2, and a drive mechanism for driving the storage tank 2 is installed on one side of the top of the trailer platform 1.

[0022] By adopting the above technical solution, this utility model, through the spray mechanism and drive mechanism, facilitates the rotation of the lead screw 9 driven by the first motor 10, thereby driving the adjusting plate 11 to move between the two fixed plates 8. The function of the limiting hole 12 and the first limiting groove 7 can drive the first limiting rod 6 to move in an arc shape, thereby driving one end of the spray cannon 4 to rotate on the two support plates 3. The second motor 16 drives the drive gear 17 to rotate, thereby causing the meshing arc rack 15 to rotate. The two second limiting rods 21 move within the two second limiting grooves 20, thereby causing the storage tank 2 to rotate, which in turn drives the spray cannon 4 located at the top of the storage tank 2 to rotate laterally. In conjunction with the rotation direction driven by the first motor 10, the spray range of the spray cannon 4 can be improved.

[0023] Reference Figure 1-4 The spraying mechanism includes two sets of support plates 3. A spray cannon 4 for spraying atomized water is rotatably installed between the support plates 3. One end of the spray cannon 4 is connected to the bottom of the storage tank 2.

[0024] By adopting the above technical solution, the spray cannon 4 can be easily driven to adjust its angle during the spraying process, thereby increasing the spraying range of the spray cannon 4.

[0025] Reference Figure 1-4 Limiting plates 5 are fixedly installed on both sets of support plates 3. First limiting rods 6 are fixedly installed at both ends of one side of the spray cannon 4. First limiting grooves 7 are opened on both limiting plates 5, and the two first limiting rods 6 are respectively movably installed in the two first limiting grooves 7.

[0026] By adopting the above technical solution, the first limiting groove 7 and the first limiting rod 6 are provided to facilitate the movement of the first limiting rod 6 within the first limiting groove 7 when the spray cannon 4 is rotated, thereby enabling one side of the spray cannon 4 to rotate with the other side of the spray cannon 4, thus adjusting the angle of the spray cannon 4.

[0027] Reference Figure 1-4 Both ends of one side of the limiting plate 5 are fixedly installed with fixing plates 8. Both sides between the two fixing plates 8 are rotatably installed with lead screws 9. One end of the two lead screws 9 is driven by a first motor 10. The two first motors 10 are fixedly installed on the top of a fixing plate 8. Adjusting plates 11 are threaded on the two lead screws 9.

[0028] By adopting the above technical solution, the adjustable plate 11 can be easily driven by the lead screw 9 to move up and down between the two fixed plates 8, thereby driving the first limiting rod 6 to move upward. Through the limiting of the first limiting groove 7, one side of the spray cannon 4 rotates in an arc shape.

[0029] Reference Figure 1-4 One end of each of the two adjusting plates 11 has a limiting hole 12, and one side of each of the two first limiting rods 6 is movably disposed in the two limiting holes 12. Both ends of the two fixing plates 8 are equipped with a first switch 13 for adjusting the rotation direction of the first motor 10.

[0030] By adopting the above technical solution, the first switch 13 is set so that when the adjusting plate 11 moves to the end of the fixed plate 8, the first switch 13 can be activated, thereby allowing the first switch 13 to transmit an electrical signal to the first motor 10, which in turn causes the first motor 10 to rotate in the direction of rotation.

[0031] Reference Figure 1-4 The drive mechanism includes a mounting bracket 14 and an arc-shaped rack 15. A second motor 16 is fixedly mounted on the mounting bracket 14, and a drive gear 17 is fixedly mounted on the output shaft of the second motor 16. The drive gear 17 and the arc-shaped rack 15 are meshed together.

[0032] By adopting the above technical solution, the arc-shaped rack 15 facilitates the rotation of the drive gear 17 by the second motor 16, thereby driving the arc-shaped rack 15, which in turn drives the storage tank 2 to rotate, causing the spray cannon 4 located at the top of the storage tank 2 to rotate laterally.

[0033] Reference Figure 1-4 The arc-shaped rack 15 is fixedly connected to one side of the storage tank 2. Connecting plates 18 are fixedly installed on both sides of the top of the trailer plate 1. A second switch 19 for driving the second motor 16 to rotate in the opposite direction is installed on one end of each connecting plate 18.

[0034] By adopting the above technical solution, the second switch 19 is set so that when one end of the arc-shaped rack 15 rotates to a certain position, it can push the second switch 19, thereby enabling the second switch 19 to transmit an electrical signal to the second motor 16, which in turn enables the second motor 16 to drive in reverse.

[0035] Reference Figure 1-4 The trailer plate 1 has two second limiting grooves 20 on both sides of its top end. A second limiting rod 21 is movably installed in each of the two second limiting grooves 20, and the top ends of the two second limiting rods 21 are fixedly connected to the bottom end of the storage tank 2.

[0036] By adopting the above technical solution, the second limiting groove 20 and the second limiting rod 21 are provided, which facilitate the movement of the second limiting rod 21 within the second limiting groove 20, thereby limiting the storage tank 2 which is fixedly connected to the second limiting rod 21 and maintaining the stability of the storage tank 2.

[0037] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
