It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0025] The following describes the specific implementation of the present utility model in detail with reference to specific embodiments.

[0026] Please refer to Figures 1 to 5 , a dust suppression spraying device for construction engineering construction provided by an embodiment of the present utility model, the dust suppression spraying device for construction engineering construction includes: an electric trolley 1.

[0027] In an embodiment of the present utility model, please refer to Figure 1 , Figure 2 and Figure 3, a water storage tank 2 is provided on the electric trolley 1, a spray tube 3 is provided above the water storage tank 2, a connecting component 4 for supporting the spray tube 3 is provided on the water storage tank 2, and adjusting components 6 for adjusting the port specifications of both sides of the spray tube 3 are provided on both sides of the spray tube 3; the adjusting component 6 includes a support ring 61, the support ring 61 is sleeved on the end of the spray tube 3, several annularly distributed connecting frames 611 are provided on one side of the outer wall of the support ring 61 close to the end of the spray tube 3, two rotatably connected shaft rods 612 are provided inside the connecting frame 611, a sealing piece 62 is provided on the shaft rod 612 close to the center of the spray tube 3, an adjusting motor 615 is provided at the end of the shaft rod 612 far from the center of the spray tube 3, a driving tooth 613 is sleeved on the center of the outer wall of the shaft rod 612, a linkage tooth 614 which is meshed and connected is provided outside the driving tooth 613, the linkage tooth 614 is sleeved on the other shaft rod 612, and a flexible connecting piece 63 is provided between adjacent two sealing pieces 62.

[0028] It should be noted that: through the setting of the adjusting component 6, during later use, the staff can control the unfolding angles of several sealing pieces 62 in the adjusting component 6, and then can change the opening area of the port surrounded by several sealing pieces 62. By reducing the opening area, the distance of the sprayed water mist can be made farther during use, and by increasing the opening area, the distance of the sprayed water mist can be reduced and the spraying range can be increased during use, so that the later use of the device can be more flexible;

[0029] And through the setting of the flexible connecting piece 63, the flexible connecting piece 63 can seal the gap between adjacent two sealing pieces 62. Therefore, during later horizontal spraying, the water mist can only be ejected from the port parts of the sealing pieces 62, reducing the phenomenon of water mist leaking everywhere, so that more accurate control of the water mist can be realized.

[0030] In the embodiment of the present utility model, please refer to Figure 1 、 Figure 2 and Figure 4 , the connecting component 4 includes a support frame 41, the bottom of the support frame 41 abuts against and is slidably connected to the top of the water storage tank 2, a horizontal driving motor 42 is provided inside the support frame 41, and the horizontal driving motor 42 is connected to the water storage tank 2. The inner top of the support frame 41 is rotatably connected to the spray tube 3 through a rotating shaft. A vertical driving motor 43 is provided on one side of the outer wall of the support frame 41, and the output end of the vertical driving motor 43 is fixedly connected to one end of the rotating shaft for erecting the spray tube 3.

[0031] It should be noted that: through the setting of the connecting component 4, during use, the horizontal driving motor 42 and the vertical driving motor can be controlled to rotate as needed. The rotating horizontal driving motor 42 can drive the spray nozzle 3 to rotate in the horizontal direction through the support frame 41, and the working vertical driving motor can drive the spray nozzle 3 to rotate in the vertical direction, thereby realizing the all-round angle adjustment of the spray nozzle 3 and further improving the flexibility of the device during later use.

[0032] In an embodiment of the present utility model, please refer to Figure 2 and Figure 4 , an air inlet hole 32 is provided at the center inside the spray nozzle 3, and fans 31 are provided on both sides inside the spray nozzle 3.

[0033] It should be noted that: through the setting of the air inlet hole 32, when the fans 31 are working, the external air can smoothly enter the inside of the spray nozzle 3, and then the air can smoothly circulate inside the spray nozzle 3. And through the circulation of the air, the water mist sprayed out by the nozzle 521 can be blown, and dust reduction operation can be carried out when spraying outward.

[0034] In an embodiment of the present utility model, please refer to Figure 1 , Figure 2 and Figure 5 , a water supply component 5 for outputting water source is provided on the water storage tank 2. The water supply component 5 includes a water pump 51. The water pump 51 is provided on the water storage tank 2. The input end of the water pump 51 is communicated with the inside of the water storage tank 2. A three-way pipe 511 is provided at the output end of the water pump 51. Valves 512 are provided on both branches of the three-way pipe 511 away from the water pump 51.

One end of the connecting hose 513 away from the three-way pipe 511 is provided with a communicating water guide ring 52. The water guide ring 52 is located on one side near the port inside the spray nozzle 3. A number of communicating nozzles 521 are provided on one side of the outer wall of the water guide ring 52 near the port of the spray nozzle 3.

[0035] It should be noted that: through the setting of the water supply component 5, during use, by controlling the opening state of the corresponding valve 512, the state of the outlet sprayed by the spray nozzle 3 during the use of the device can be controlled, and thus the device can be flexibly adjusted for single-way spraying and two-way spraying at will. And through the setting of the connecting hose 513, when the angle of the spray nozzle 3 is adjusted by the support component later, the connecting hose 513 can move along with the adjustment of the spray nozzle 3, so that the water supply component 5 can smoothly supply water.

[0036] The working principle of the dust reduction spray device for construction engineering provided by the present utility model is as follows:

[0037] In the later stage of using this device, the staff can first control the horizontal drive motor 42 and the adjustment motor 615 to rotate according to needs. The rotating horizontal drive motor 42 can drive the spray nozzle 3 to rotate horizontally through the support frame 41, and the working vertical drive motor can drive the spray nozzle 3 to rotate vertically, thereby realizing the all-round angle adjustment of the spray nozzle 3;

[0038] After completing the angle adjustment of the spray nozzle 3, the staff can control the water pump 51 in the water supply component 5 to work. The working water pump 51 can input the water source in the water storage tank 2 into the spray head 521 through the three-way pipe 511 and the connecting hose 513, and spray it out through the spray head 521. At this time, the working fan 31 can blow outwards, and the flowing wind force can drive the water mist sprayed by the spray head 521 to spray outwards;

[0039] During this process, the staff can also control the adjustment motor 615 to work. The working adjustment motor 615 can drive the corresponding shaft 612 to rotate, and drive the drive gear 613 on the outer wall to rotate through the shaft 612. At this time, the drive gear 613 can drive the corresponding sealing piece 62 to rotate through the meshing with the outer wall linkage gear 614. By adjusting multiple sealing pieces 62, the size of the annular opening structure formed by multiple sealing pieces 62 can be changed;

[0040] By reducing the opening area, the sprayed water mist can be made to travel farther during use, and by increasing the opening area, the spraying distance of the water mist can be reduced and the spraying range can be increased during use, thereby making the later use of this device more flexible. Thus, this device can be smoothly used for dust reduction operations.

[0041] The circuits and controls involved in this utility model are all prior arts and will not be elaborated here.

[0042] The above are only the embodiments of this utility model, and do not limit the patent scope of this utility model accordingly.
