[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Reference Figures 1-7 The present invention provides a construction dust reduction treatment device, comprising: A mobile body 1; a pair of spray pipes 2, which are arranged on the mobile body 1, and a lifting member is arranged on the mobile body 1, and a lifting end of the lifting member is connected to an adjusting seat 3, and a driving assembly is arranged on the adjusting seat 3, and a driving end of the driving assembly is connected to the pair of spray pipes 2, so that the pair of spray pipes 2 rotate relative to the adjusting seat 3, and the pair of spray pipes 2 rotate synchronously in opposite directions, and in the dust reduction process, the spray pipes 2 reciprocate in a direction away from the adjusting seat 3; The fan 4 is arranged on the mobile body 1. The mobile body 1 is connected with a transfer rod 5. The transfer rod 5 is fixedly connected to the fan 4 so that the fan 4 can rotate relative to the mobile body 1. The air outlet end of the fan 4 faces the spray pipe 2. The rotating plate 6 is connected to the top surface of the moving vehicle body 1 , and a pair of spray pipes 2 and the fan 4 are arranged on the rotating plate 6 .

[0021] In the present invention, a pair of spray pipes 2 are arranged on a moving vehicle body 1. A lifting member is used to adjust the height of an adjusting seat 3, and the pair of spray pipes 2 are arranged on the adjusting seat 3. A driving assembly is used to drive and control the pair of spray pipes 2, so that the pair of spray pipes 2 can rotate relative to each other and also relative to the adjusting seat 3. In addition, during the spraying process of the spray pipes 2, they reciprocate relative to the moving vehicle body 1, thereby fully improving the spraying range of the spray pipes 2. Combined with a fan 4 arranged on the moving vehicle body 1, by the fan 4 blowing air towards the spray pipes 2, the coverage range of the sprayed water mist can be further expanded. Moreover, a rotating plate 6 drives the fan 4 and the spray pipes 2 to rotate relative to the moving vehicle body 1, so that the spray pipes 2 and the fan 4 rotate synchronously and spray and dust fall along the circumferential direction of the moving vehicle body 1 into the construction site, achieving an improvement in the working efficiency of the dust fall treatment work.

[0022] Specifically, a water tank 7 is also fixedly connected to the moving vehicle body 1. On the premise of not affecting the rotation of the rotating plate 6, the water tank 7 is communicated with the pair of spray pipes 2 through a connecting pipe 8, and a pump 9 is arranged on the connecting pipe 8 to introduce water into the spray pipes 2 and atomize and spray and dust fall into the construction site through the nozzles.

[0023] It can be understood that the lifting member adopts a common multi-stage telescopic hydraulic cylinder 10, and the top end of the piston rod of the multi-stage telescopic hydraulic cylinder 10 is fixedly connected to the adjusting seat 3.

[0024] Furthermore, the driving assembly includes: A transfer plate 11, one end of which is pivotally connected to the adjusting seat 3 through a rotating shaft 12. An installation plate 13 is fixedly connected to one side of the adjusting seat 3, and a first driving motor 14 is fixedly connected to the installation plate 13. The output shaft of the first driving motor 14 is coaxially fixedly connected to the rotating shaft 12; A first cylinder 15 is fixedly connected to the end of the transfer plate 11 far from the adjusting seat 3. The piston rod of the first cylinder 15 is fixedly connected to a connecting seat 16, and a reciprocating part reciprocates on the connecting seat 16, and the reciprocating part is connected to the pair of spray pipes 2.

[0025] The first driving motor 14 drives the rotating shaft 12 to rotate, so that the transfer plate 11 rotates relative to the adjusting seat 3, driving the spray pipes 2 to rotate with the adjusting seat 3. The first cylinder 15 connects the connecting seat 16 to the transfer plate 11, and the connecting seat 16 is connected to the pair of spray pipes 2 through the reciprocating part, so that while the spray pipes 2 are rotating, the distance between the spray pipes 2 and the transfer plate 11 can also be adjusted, and the reciprocating part is used to drive the spray pipes 2 to achieve the reciprocating movement of the spray pipes 2 and improve the spraying range.

[0026] Furthermore, the reciprocating part includes: A moving plate 17, a chute is formed in the connecting seat 16, and the moving plate 17 is slidably connected in the chute in a limited manner and is connected to the pair of spray pipes 2; The reciprocating screw 18 is connected in the slide slot, and the moving plate 17 is threadedly sleeved on the reciprocating screw 18; The second drive motor 19 is fixedly connected in the connecting seat 16 , and the output shaft of the second drive motor 19 is coaxially fixedly connected with the reciprocating screw 18 .

[0027] In this technical solution, the movable plate 17 is connected to a pair of spray pipes 2, the second drive motor 19 is used to drive the reciprocating screw 18 to rotate, the movable seat is threadedly sleeved on the reciprocating screw 18, and the movable seat and the connecting seat 16 are limitedly slidably connected to realize the reciprocating motion of the movable plate 17, thereby causing the reciprocating motion of the pair of spray pipes 2.

[0028] Furthermore, a pair of limiting columns 20 are fixedly connected to the movable plate 17 symmetrically along the center.

[0029] Furthermore, it also includes: The driving seat 21 is slidably connected to the end of the connecting seat 16 away from the first cylinder 15. The driving seat 21 is fixedly connected to the movable plate 17 through the limiting column 20. An empty slot is opened on the driving seat 21, and a pair of spray pipes 2 are symmetrically arranged on both sides of the empty slot along the center. The third driving motor 22 is fixedly connected in the driving seat 21. The output shaft of the third driving motor 22 is connected to a pair of spray pipes 2 through a transmission member so that the pair of spray pipes 2 rotate synchronously in opposite directions. The transmission member is a self-locking structure.

[0030] The driving seat 21 is slidably connected to the connecting seat 16, and the movable plate 17 is fixed to the driving seat 21 by using the limiting column 20. The reciprocating motion of the movable plate 17 drives the pair of spray pipes 2 to move, thereby increasing the spray coverage area. The third driving motor 22 can be connected to the pair of spray pipes 2 through the transmission member, so that the spray pipes 2 can rotate synchronously to adjust the spray angle. The transmission member of the self-locking structure can keep the pair of spray pipes 2 stably fixed and maintained at the adjusted angle position after the third driving motor 22 stops.

[0031] Furthermore, the transmission member includes: The worm 23 is coaxially fixed to the output shaft of the third driving motor 22, and the worm 23 is transferred into the empty slot; A pair of worm wheels 24 are connected to a pair of spray pipes 2 one by one. A support rod 25 is fixedly connected to the axis of the worm wheel 24. The two ends of the support rod 25 are connected to the opposite sides of the inner wall of the empty groove. The pair of worm wheels 24 are symmetrically meshed on both sides of the worm 23 along the center.

[0032] When the worm 23 rotates, the pair of worm wheels 24 rotate in opposite directions, thereby controlling the pair of spray pipes 2 to rotate relative to each other to expand or close, thereby adjusting the spray angle. When the pair of spray pipes 2 are coaxially distributed in the horizontal direction, the maximum spray angle is achieved.

[0033] Further, fixed seats 26 are fixedly connected to the mutually remote ends of a pair of worm wheels 24. Grooves are formed in the fixed seats 26. One end of the spray pipe 2 extends into the groove, and a support rod 27 is inserted through the part of the spray pipe 2 extending into the groove. The support rod 27 is rotatably connected to the fixed seat 26. A torsion spring 28 is wound around the support rod 27, and both ends of the torsion spring 28 are fixedly connected to the support rod 27 and the fixed seat 26 respectively.

[0034] The support rod 27 is elastically connected to the fixed seat 26 through the torsion spring 28, and the spray pipe 2 is fixedly connected to the support rod 27, so that the spray pipe 2 is elastically rotatably connected to the fixed seat 26. When the moving plate 17 reciprocates, the driving seat 21 drives a pair of spray pipes 2 to reciprocate. During this process, the spray pipe 2 elastically rotates relative to the fixed seat 26, thereby generating an elastic swinging effect, which can further expand the original spraying range of the spray pipe 2, throw the water mist out, and reduce dust in the construction site.

[0035] Further, a support 29 is fixedly connected to the top surface of the rotating plate 6. Both sides of the fan 4 are rotatably connected to the support 29 through the rotating rods 5. A fourth driving motor 31 is fixedly connected to the outer side wall of the support 29, and the output shaft of the fourth driving motor 31 is fixedly connected to the adjacent rotating rod 5.

[0036] The fourth driving motor 31 drives the rotating rod 5 to rotate, so as to adjust the rotating angle of the fan 4, make the fan 4 blow air towards the spraying end of the spray pipe 2, improve the diffusion distance of the atomized water droplets, and increase the dust reduction treatment range.

[0037] Further, a circular groove is formed in the top surface of the moving vehicle body 1. The inner wall of the bottom end of the circular groove is rotatably connected to a driven gear 32, and the top end of the driven gear 32 is fixedly connected to the rotating plate 6. A fifth driving motor 34 is fixedly connected inside the moving vehicle body 1, and a driving gear 33 is fixedly connected to the output shaft of the fifth driving motor 34. The driving gear 33 meshes with the driven gear 32.

[0038] The fifth driving motor 34 drives the driving gear 33 to rotate, and the driving gear 33 rotates the driven gear 32, realizing the rotation of the rotating plate 6. And since both the fan 4 and the spray pipe 2 are fixed on the rotating plate 6, the relative position between the fan 4 and the spray pipe 2 is kept stable, realizing the synchronous movement of the fan 4 and the spray pipe 2 while rotating and spraying, and diffusing the atomized water droplets.

[0039] Further, support rods 35 are respectively fixedly connected to the four circumferences of the bottom end of the moving vehicle body 1. A Fukushima wheel 36 is installed on one side of the support rod 35, and the Fukushima wheel 36 selectively makes rolling contact with the ground or not.

[0040] By adopting the caster wheel 36, the lifting can be selectively adjusted. When it is necessary to move the vehicle body 1, the caster wheel 36 is lifted so that the caster wheel 36 is in rolling contact with the ground, meeting the requirement of moving the vehicle body 1. When performing spray dust suppression at a fixed point, the caster wheel 36 is lifted, and the vehicle body 1 is fixed by the abutting rod 35 abutting against the ground.

[0041] The working principle of the construction dust suppression treatment device of the present invention: After moving the vehicle body 1 to the construction site, the caster wheel 36 is lifted to fix the vehicle body 1 on the ground. The multi-stage telescopic hydraulic cylinder 10 is controlled to lift the adjusting seat 3, and the first driving motor 14 rotates the rotating shaft 12 to rotate and unfold the adapter plate 11, so that a pair of spray pipes 2 extend horizontally. Through the stretching of the first cylinder 15, the spray pipes 2 are moved away from the adapter plate 11. At the same time, the third driving motor 22 rotates the worm 23, and the worm 23 meshes with a pair of worm wheels 24 to unfold a pair of spray pipes 2. The water in the water tank 7 is sent into the spray pipes 2 by the pump 9 to suppress dust in the site.

[0042] During the dust suppression process, the second driving motor 19 is started to rotate the reciprocating lead screw 18. The reciprocating lead screw 18 is threadedly connected with the moving plate 17. The driving seat 21 is driven to reciprocate through the moving plate 17 and the limiting column 20, so as to realize the reciprocating movement of a pair of spray pipes 2. Moreover, during the reciprocating movement of the driving seat 21, due to the elastic action of the torsion spring 28 on the support rod 27, the spray pipes 2 elastically rotate around the fixed seat 26, enabling the spray pipes 2 to have a larger spray range. The fourth driving motor 31 is used to rotate the adapter rod 5 to realize the rotation of the fan 4, and the air outlet end of the fan 4 is directed towards the spray pipes 2 to further increase the diffusion range of the atomized water droplets.

[0043] As the dust suppression progresses, by starting the fifth driving motor 34, the driving gear 33 is driven to rotate the driven gear 32, driving the rotating plate 6 to rotate, driving the spray pipes 2 and the fan 4 to rotate synchronously, and performing area dust suppression in the dust suppression site.
