Detailed implementation manners

[0020] The following will further describe the present application in detail with reference to the attached Figures 1-3 drawings.

[0021] An embodiment of the present application discloses a dust suppression spray component. Referring to Figures 1-3 , a dust suppression spray component includes a base 1. Fixed plates 2 are installed at both ends of the top of the base 1. Side plates 3 are slidably connected inside the fixed plates 2. A fixed pipe 4 is installed between the two side plates 3. A support frame 41 is installed on the side wall of the fixed pipe 4. An installation groove 42 is formed in the support frame 41. A spray head 6 is rotatably connected to the inside of the installation groove 42 through a rotating shaft 5. The spray head 6 is communicated with the fixed pipe 4 through a hose 61. And a driving component 7 for driving the spray head 6 to rotate around the rotating shaft 5 is arranged on the support frame 41. The driving component 7 includes a moving rack 73 slidably arranged inside the support frame 41. A plurality of gears 74 are meshed with the moving rack 73. The plurality of gears 74 are respectively fixedly installed on the outer sides of the corresponding rotating shafts 5. And a driving motor 71 is fixedly installed on the side wall of the support frame 41. A cam 72 for abutting against the moving rack 73 is fixedly installed on the output shaft of the driving motor 71. And a tension spring 75 for pulling the moving rack 73 to move is installed on the other side wall of the support frame 41.

[0022] Here, by starting the driving motor 71, the driving motor 71 can drive the cam 72 to rotate. The cam 72 presses the moving rack 73 and cooperates with the pulling spring, so that the moving rack 73 can move left and right. When the moving rack 73 moves left and right, it can drive the gears 74 and the rotating shaft 5 to rotate reciprocally, and drive the spray head 6 to rotate around the rotating shaft 5 reciprocally, thereby expanding the spraying range of the spray head 6 and improving the practicability of the device.

[0023] Referring to Figure 2, a limiting groove is provided on the outer wall of the cam 72, and the end of the moving rack 73 extends into the interior of its limiting groove.

[0024] By providing a limiting groove on the outside of the cam 72 here, the moving rack 73 can be better squeezed.

[0025] Refer to Figure 3 , a threaded rod 11 is rotatably connected to the base 1, and a connecting plate 31 is threadedly connected to the outside of the threaded rod 11. The connecting plate 31 is fixedly connected to the two side plates 3.

[0026] By rotating the threaded rod 11 here, the threaded rod 11 can push the connecting plate 31 to move up and down, so that the height of the fixed pipe 4 and the spray pipe can be adjusted, improving the practicability of the device.

[0027] Refer to Figure 1 , a water pump 33 is fixedly installed on the side wall of the side plate 3. The output end of the water pump 33 is communicated with the fixed pipe 4, and the input end of the water pump 33 is communicated with a water tank 32 installed on the top of the connecting plate 31 through a connecting pipe.

[0028] By starting the water pump 33 here, the water pump 33 can send the dust suppression liquid inside the water tank 32 into the fixed pipe 4 and spray it out through the hose 61 and the spray head 6 for dust suppression operation.

[0029] Refer to Figure 3 , a turntable 12 is fixedly installed on the top of the threaded rod 11, and a plurality of anti-slip grooves are provided in the circumferential direction of the turntable 12.

[0031] The implementation principle of a dust suppression spray assembly in an embodiment of the present application is as follows: when in use, place the device at a designated position, then connect the power supply, and start the water pump 33. The water pump 33 can send the dust suppression liquid inside the water tank 32 into the fixed pipe 4 and spray it out through the hose 61 and the spray head 6 to achieve the dust suppression operation; at the same time, by starting the driving motor 71, the driving motor 71 drives the cam 72 to rotate. The cam 72 cooperates with the tension spring 75, so that the moving rack 73 can move left and right. The moving rack 73 meshes with the gear 74, thereby driving the spray head 6 to rotate around the rotating shaft 5, so that the spraying dust suppression area can be expanded, improving the practicability of the device. Secondly, the device can rotate the turntable 12, the turntable 12 can drive the threaded rod 11 to rotate, the threaded rod 11 can push the connecting plate 31 to move up and down, and the connecting plate 31 drives the side plate 3, the fixed pipe 4 and the spray head 6 to move up and down, so that the height of the spraying can be adjusted.
