[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 , the utility model provides a technical solution: a gravel spraying device, comprising a U-shaped frame 1, a spraying assembly 2 is arranged on the top of the U-shaped frame 1, and anti-dumping assemblies 3 are arranged on both sides of the U-shaped frame 1;

[0023] The spray assembly 2 includes a first pipe 21, which is rotatably installed through the center of the top of the U-shaped frame 1, and the lower end of the first pipe 21 is connected to a water collecting plate 25, and a spray head 26 is provided at the bottom of the water collecting plate 25. The upper end of the first pipe 21 is rotatably installed with a second pipe 23 through a sealing bearing 22, and the outer wall of the second pipe 23 is fixedly connected to the top of the U-shaped frame 1 through a fixing rod 24;

[0024] A motor 27 is fixed on the top of the U-shaped frame 1 , a first gear 28 is fixed to the output end of the top of the motor 27 , a second gear 29 is meshed with one side of the first gear 28 , and the inner wall of the second gear 29 is fixedly connected to the outer wall of the first pipe 21 .

[0025] The anti-dumping assembly 3 includes a movable ring 31, which is nested on both sides of the U-shaped frame 1. A support rod 32 is rotatably mounted on the outer wall of the movable ring 31, and a bottom plate 33 is rotatably mounted on the lower end of the support rod 32. A fixing bolt 34 penetrates the interior of the bottom plate 33.

[0026] Two fixing rods 24 are provided, and the fixing rods 24 are symmetrically distributed about the central axis of the second pipe 23 , so that the second pipe 23 can be stably fixed, which is beneficial to the rotation of the first pipe 21 .

[0027] The spray heads 26 are evenly spaced at the bottom of the water collecting plate 25, thereby increasing the spray range and improving the dust reduction range.

[0028] The movable ring 31 and the U-shaped frame 1 are threadedly connected. Three support rods 32 are provided on the movable ring 31 . The height of the movable ring 31 can be adjusted, so that the support angle of the support rods 32 can be adjusted.

[0029] Working principle: When using the gravel spraying device, first rotate the movable ring 31 to move the movable ring 31 on the U-shaped frame 1. After the movable ring 31 moves to a suitable position, rotate the support rod 32 to make the bottom plate 33 at the bottom of the support rod 32 contact the ground, and then insert the fixing bolt 34 on the bottom plate 33 into the ground, thereby completing the fixing of the bottom plate 33. Since three support rods 32 are arranged on the movable ring 31, the support rods 32 play a good supporting role on the U-shaped frame 1, preventing the U-shaped frame 1 from tipping over, and at the same time allowing the water collecting plate 25 to rotate stably;

[0030] First, the end of the second pipe 23 is connected to the water source and the water pump, and the water pump is started, so that the water in the water source can enter the interior of the water collecting plate 25 through the second pipe 23 and the first pipe 21, and finally the water mist is sprayed out through the spray head 26, and then the motor 27 is started. At this time, the motor 27 drives the first gear 28 to rotate, and then the first gear 28 rotates simultaneously through the second gear 29, the first pipe 21, the water collecting plate 25 and the spray head 26. Under the action of centripetal force, the spray range of the spray head 26 is increased, thereby increasing the dust reduction range, which can effectively reduce the dust generated by the broken stones.

[0031] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
