[0033] When in use, the fog cannon mechanism 3 can swing back and forth under the drive of the driving mechanism 2, thereby increasing the atomization spray range, that is, the dust reduction range. When the driving motor 206 rotates, the driving gear 2061 can drive the rotating disk 203 to rotate through the rotating gear 2031. When the rotating disk 203 rotates, it can drive the driving block 205 to rotate synchronously.

The gear teeth of the swinging gear 2041 and the reciprocating rack 2022 are engaged for transmission. When the reciprocating disk 202 moves back and forth, the reciprocating rack 2022 can drive the swinging base 204 to rotate back and forth through the swinging gear 2041, thereby realizing the swinging action of the swinging base 204, so that the fog cannon mechanism 3 installed on the top of the swinging base 204 will also swing back and forth, thereby realizing the function of increasing the atomization spraying range, and being flexible and convenient to use.

[0034] Among them, the side of the adjusting rod 401 is provided with a locking top spring 4012, and the two ends of the locking top spring 4012 respectively press against the side of the adjusting rod 401 and the inside of the rotating disk 203, the outside of the adjusting rod 401 is provided with a locking gear 4013, and the inside of the rotating disk 203 is provided with a locking tooth groove 2032. Under the action of the locking top spring 4012, when the adjusting rod 401 is not resisted by an external force, the locking gear 4013 is inserted into the inside of the locking tooth groove 2032. In use, the maximum swing angle of the fog cannon mechanism 3 can be adjusted by the adjusting mechanism 4, and the adjusting mechanism 4 can lock the current swing angle of the fog cannon mechanism 3 when it is in the reset state (the adjusting rod 401 is not pressed by an external force), so that the fog cannon mechanism 3 will not accidentally change the swing angle setting value when in use; Under the action of the spring 4012, the locking gear 4013 is inserted into the inside of the locking tooth groove 2032, so that the adjusting rod 401 cannot rotate. The side of the adjusting rod 401 is provided with a synchronization rod 4011 with a regular polygonal cross-section, and the interior of the positioning rod 402 is provided with a synchronization groove 4021. The synchronization rod 4011 is inserted into the interior of the synchronization groove 4021. The synchronization rod 4011 of the adjusting rod 401 can pass through the synchronization groove 4021 to prevent the positioning rod 402 from rotating. Therefore, when the positioning rod 402 does not rotate, the use position of the driving block 205 will not change through the action of the thread of the driving block 205, so that the rotation radius of the driving block 205 when following the rotation of the rotating disk 203 will not change, and the set swing angle of the swing seat 204 will not change, and it is stable to use.

[0035] Among them, the outside of the rod body of the positioning rod 402 is provided with a thread, and the positioning rod 402 is screwed to the inside of the driving block 205 through the rod body thread. In use, when it is necessary to adjust the swing angle of the fog cannon mechanism 3, it is only necessary to press and rotate the adjusting rod 401. When the adjusting rod 401 is pressed, the locking gear 4013 will be out of the locking tooth groove 2032, and the locking top spring 4012 will be compressed. After that, the adjusting rod 401 can rotate freely, and when the adjusting rod 401 rotates, the synchronization rod 4011 can drive the positioning rod 401 through the synchronization groove 4021. 2 rotation, the positioning rod 402 can drive the driving block 205 to move along the radial direction of the rotating disk 203 through the rod body thread when rotating. After the driving block 205 moves, the rotation radius when it follows the rotating disk 203 is changed, thereby changing the maximum reciprocating distance of the reciprocating disk 202, and further changing the maximum angle that the reciprocating disk 202 can drive the swing seat 204 to rotate.

After the adjustment is completed and the adjustment rod 401 is released, the adjustment mechanism 4 will automatically reset under the action of the locking top spring 4012 to prepare for the next adjustment.

[0036] The specific usage and function of this embodiment: In the present invention, the sprinkler truck body 1 can realize the function of cleaning and flushing the ground, and the water pump inside the water tank can pump the water into the cleaning pipe and then spray it out, thereby cleaning and cleaning the dust, dirt and impurities on the ground. At the same time, the dust reduction component can achieve the dust reduction effect, and the water pump can pump the water into the interior of the atomizing nozzle 304 through the water pump and the pipe and spray it out in atomization. Under the entrainment and acceleration of the air flow blown out by the fan inside the fog cannon barrel 302, the water mist is sprayed out at a specific diffusion angle and range. The wind flow generated by the fan not only gives the water mist greater kinetic energy, so that it can cover a longer distance and a wider area, but also promotes the water mist to diffuse evenly in the space, thereby achieving the purpose of efficient dust reduction. The fog cannon mechanism 3 can be driven by the driving mechanism 2 when in use. When the driving motor 206 rotates, the driving gear 2061 can drive the rotating disk 203 to rotate through the rotating gear 2031, and the rotating disk 203 can drive the driving block 205 to rotate synchronously. When the driving block 205 follows the rotation of the rotating disk 203, the driving lever 2051 can drive the reciprocating disk 202 to move back and forth laterally inside the mounting seat 201 through the reciprocating slot 2021. When the reciprocating disk 202 moves back and forth, the reciprocating rack 2022 can drive the swing seat 204 to rotate back and forth through the swing gear 2041, that is, the swinging action of the swing seat 204 is realized, so that the fog cannon mechanism 3 installed on the top of the swing seat 204 will also swing back and forth, thereby realizing the function of increasing the atomizing spraying range; The maximum swing angle of the fog cannon mechanism 3 can be adjusted by the adjustment mechanism 4, and the adjustment mechanism 4 can lock the current swing angle of the fog cannon mechanism 3 when it is in the reset state (the adjustment rod 401 is not pressed by external force), so that the fog cannon mechanism 3 will not accidentally change the swing angle setting value when in use. Under the action of the locking top spring 4012, the locking gear 4013 is inserted into the locking tooth groove 2032, so that the adjustment rod 401 cannot rotate, and the synchronization rod 4011 of the adjustment rod 401 can make the positioning rod 402 unable to rotate through the synchronization groove 4021. Therefore, when the positioning rod 402 is not rotating, the use position of the driving block 205 will not change through the action of the thread of the driving block 205, so that the rotation radius of the driving block 205 when following the rotation of the rotating disk 203 will not change, and the set swing angle of the swing seat 204 will not change. When the adjusting rod 401 is pressed, the locking gear 4013 will be disengaged from the locking tooth groove 2032, and the locking top spring 4012 will be compressed. Thereafter, the adjusting rod 401 can rotate freely, and when the adjusting rod 401 rotates, the synchronous rod 4011 can drive the positioning rod 402 to rotate through the synchronous groove 4021. When the positioning rod 402 rotates, it can drive the driving block 205 to move along the radial direction of the rotating disk 203 through the rod body thread. After the driving block 205 moves, it will change its rotation radius when following the rotating disk 203, thereby changing the maximum distance when the reciprocating disk 202 reciprocates, and further changing the maximum angle that the reciprocating disk 202 can drive the swing seat 204 to rotate. It is convenient to adjust and flexible to use. After the adjustment is completed and the adjusting rod 401 is released, the adjusting mechanism 4 will automatically reset under the action of the locking top spring 4012 for the next adjustment.
