Of course, there are also systems that use sprinkler trucks to replace conventional sprinkler systems, adding different numbers of sprinkler trucks for different blasting areas, thereby achieving a certain degree of comprehensive coverage of the blasting area. However, existing sprinkler truck systems have the problem that the water spraying position adjustment process requires manual assistance. Although they can spray water at fixed points in different dust areas, manual assistance is also affected by the dust on site, which cannot guarantee the personal safety of people, affects the water spraying and dust suppression process, and cannot meet the usage requirements.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0016] Examples, such as Figures 1-5As shown, a dust suppression water spraying device for open-pit mine blasting includes a dust suppression water spraying device body, which includes a support frame 1 to ensure the stability of the device. Rollers can also be installed at the lower corners of the support frame 1 to allow for easy adjustment of the device's position according to different usage needs, improving its practicality. A rotating component 2 is installed above the support frame 1, allowing for convenient horizontal adjustment of the water spraying component 10, especially suitable for different blasting zones. A mounting plate 3 is installed above the rotating component 2, with a T-shaped stabilizing frame 4 on one side. Support rods 5 are arranged at an angle above the mounting plate 3. The stabilizing frame 4 supports the support rods 5 and ensures the stability of the device. Simultaneously, the circumferential rotation of the rotating component 2 drives the mounting plate 3, stabilizing frame 4, and support rods 5 to adjust horizontally, ensuring usability. The upper end of the support rod 5 is equipped with a vertical rotation mechanism 6, which allows for convenient adjustment of the vertical position of the water spraying component 10. A vertical drive cylinder 7 is installed on the support rod 5 to provide driving power to the vertical rotation mechanism 6 for convenient adjustment of the vertical position of the water spraying component 10. A horizontal rotation adjustment component 8 is installed inside the vertical rotation mechanism 6, which allows for convenient adjustment of the horizontal position of the equipment after it has been adjusted to a suitable position, so that the equipment can perform water spraying and dust suppression in multiple directions after being oriented. The vertical rotation mechanism 6 and the horizontal rotation adjustment component 8 work together to achieve convenient adjustment of the water spraying component 10 in multiple directions to meet different usage needs. A water supply pipe 9 is installed inside the horizontal rotation adjustment component 8, and the water spraying component 10 is installed at the end of the water supply pipe 9. This can form a comprehensive spraying area, and with the multi-directional movement and adjustment of the equipment, it not only ensures the comprehensiveness of the spraying area, but also allows for targeted water spraying in dusty areas of the blasting zone to ensure dust suppression effect and meet usage requirements. In the above process: the established rotating component 2 allows for convenient multi-directional adjustment of the water spraying component 10 in the horizontal direction, especially enabling adaptive water spraying for different blasting zones; the established vertical rotating mechanism 6 allows for convenient adjustment of the vertical position of the water spraying component 10; and the established horizontal rotating adjustment component 8 allows for convenient adjustment of the horizontal position of the equipment after it has been adjusted to a suitable location, enabling the equipment to perform multi-directional water spraying and dust suppression after directional placement. The vertical rotating mechanism 6 and the horizontal rotating adjustment component 8 work together to achieve convenient multi-directional adjustment of the water spraying component 10, meeting different needs. The device meets various usage requirements. Utilizing the installed water spraying components 10, a comprehensive spraying area can be formed. With the equipment's multi-directional movement and adjustment, not only is the spraying area comprehensive, but targeted watering can also be applied to dusty areas within the blasting zone, ensuring dust suppression and meeting usage needs. This device is rationally designed, simple in structure, and easy to manufacture. Its usage direction can be freely adjusted according to different dust concentration areas within the blasting zone. In particular, it can replace manual adjustment during the equipment adjustment process, improving the device's functionality. Simultaneously, by utilizing the dust suppression spraying components, the spraying area is fully expanded, enhancing the dust suppression process and effectively meeting usage needs.
[0017] To enable convenient horizontal adjustment of the sprinkler assembly 10, especially for adaptable water spraying to different blasting zones, the rotating assembly 2 includes a rotating disk 21. A mounting plate 22 is positioned above the rotating disk 21, and rotating pulleys 23 are located at the corners of the mounting plate 22. Specifically, the rotating disk 21 is driven by a motor to rotate horizontally. The rotation of the rotating disk 21 causes the mounting plate 22 to rotate horizontally, and the rotating pulleys 23 located below the mounting plate 22 also rotate with it. The rotating pulleys 23 improve the smoothness of the mounting plate 22 in the horizontal direction and provide some support for the mounting position of the mounting plate 22, ensuring its stability and improving the functionality of the device to meet usage requirements.
[0018] To improve the functionality of the device and facilitate the adjustment of the vertical position of the sprinkler assembly 10, the vertical rotation mechanism 6 includes a support plate 61 mounted on the upper end of the support rod 5. Bearing seats 62 are located on both sides of the upper part of the support plate 61, and a rotating rod 63 is positioned between the two bearing seats 62. A rotating frame 64 is mounted on the rotating rod 63, and a connecting plate 65 is located above the rotating frame 64 and connected to the output end of the vertical drive cylinder 7. Specifically, during use, the vertical drive cylinder 7 is controlled to rotate according to different usage requirements. The extension or contraction of its output end will act on the connecting plate 65, and the connecting plate 65 will act on the rotating frame 64 as the vertical drive cylinder 7 runs. The lower part of the rotating frame 64 will rotate vertically relative to the rotating rod 63, thereby completing the convenient adjustment of the vertical position of the water spraying component 10, realizing the directional water spraying of the dust area in the blasting zone, thereby completing the dust suppression work. At the same time, it can be used in conjunction with the horizontal rotation adjustment component 8 to realize the convenient adjustment of the water spraying component 10 in multiple directions to meet different usage needs.
[0019] To facilitate convenient horizontal adjustment of the device for multi-directional water spraying and dust suppression, the horizontal rotation adjustment assembly 8 includes a rotating shaft 81 vertically arranged on the inner end of the rotating frame 64.

A drive rack 86 is located inside the limiting seat 85 and meshes with the rotating gear 82. A keyway 851 is formed on one side of the limiting seat 85. A connecting rod 87 is located at the output end of the longitudinal drive cylinder 84, which is adapted to the keyway 851 and connected to the drive rack 86. The rotating shaft 81 is located outside the rotating gear 82. The device is equipped with a swing frame 88, which supports the water pipe 9. The swing frame 88 consists of two swing plates, one of which is fixedly connected to the rotating shaft 81. It can rotate together with the rotating shaft 81. When adjusting its position, the longitudinal drive cylinder 84 is controlled to operate. Its output end acts on the connecting rod 87 and drives the drive rack 86 to slide within the limit seat 85. At the same time, it can mesh with the rotating gear 82. The rotation of the rotating gear 82 can drive the rotating shaft 81 and the swing frame 88 to rotate together, thereby enabling convenient adjustment of the position of the water pipe 9 and the water spraying assembly 10 in the horizontal direction. In particular, it can achieve directional spraying of water source for different concentrations of dust in the blasting area, thereby achieving the purpose of dust suppression and meeting the usage requirements.
[0020] To improve the rationality of the equipment setup, ensure the comprehensiveness of the water spraying area, and guarantee the smooth implementation of dust suppression, the water spraying assembly 10 includes a connecting pipe 101 connected to the water supply pipe 9. A water spraying pipe 102 is provided at the end of the connecting pipe 101. A water spraying hole 1021 is provided inside the water spraying pipe 102.

A locking pipe 104 is provided at the end of the water spraying pipe 102. An extension pipe 1031 is provided inside the discharge hood 103. A through hole 1032 is provided inside the extension pipe 1031, corresponding to the location of the water spraying hole 1021. Specifically, the established water supply... Water pipe 9 receives external water for dust suppression spraying and transports it to connecting pipe 101. The water entering connecting pipe 101 is transported to spray pipe 102, and the water in spray pipe 102 is discharged outward through spray hole 1021. At the same time, when discharged outward through spray hole 1021, it corresponds to and is discharged through through hole 1032 in extension pipe 1031. The water discharged through through hole 1032 is discharged outward along the discharge hood 103. According to the establishment of each discharge hood 103, it will be sprayed outward in a ring shape. The water spraying process between multiple adjacent discharge hoods 103 will form a multi-faceted spraying area, ensuring the dust suppression effect, improving the functionality of the device, and meeting the usage requirements.
