[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. This type of crane spray dust reduction device installs the spray device on the crane, so that the crane can solve the dust reduction problem by itself during operation, and reduce dust from the construction source. Compared with the prior art that uses a sprinkler truck or a water pipe to assist in spraying water to reduce dust, the present invention does not require additional manpower to operate the water spray equipment, saving labor costs. Only a remote control is needed to control the spray device, making the dust reduction operation more convenient. In addition, the fan-shaped water mist formed during the operation can effectively prevent dust from flying, saving water resources and not easily generating water accumulation;

[0023] 2. When it is necessary to further reduce the water mist particles, the micro motor is started through the control panel to rotate at high speed. Only the micro motor needs to work to drive the components on it to rotate. The micro motor, rotating rod, electric push rod, moving plate and through-hole needle are equivalent to a centrifugal fan that crushes the water mist particles and centrifugally decomposes the water mist particles, which is conducive to the nozzle spraying smaller water mist particles, improving the spray efficiency, and thus conducive to better dust reduction effect;

[0024] 3. If the spray hole needs to be pierced, both the micro motor and the electric push rod need to work. The micro motor can rotate the through-hole needle to correspond to the spray hole, and the electric push rod works to drive the through-hole needle into the spray hole to perform the through-hole operation. At this time, the micro motor, rotating rod, electric push rod, moving plate and through-hole needle are equivalent to through-hole components to prevent the spray hole from being blocked and affecting the water output.

The flow rate of the nozzle 11 is 1L / h. When multiple nozzles 11 are working, a fan-shaped water curtain is formed. A rotating part is installed in the center of the nozzle 11, and a transverse driving part is installed on the rotating part. Three rows of through-hole needles 17 are fixed on the transverse driving part, and the three rows of through-hole needles 17 only correspond to the spray holes 18 on one side of the nozzle 11.

[0036] like Figure 5 and 6 As shown, the rotating part includes a micro motor 12 and a rotating rod 13. The micro motor 12 is installed at the center of the inner wall on the side opposite to the spray hole 18 of the nozzle 11. The micro motor 12 is electrically connected to the control panel in the hook machine 1. The rotating rod 13 is fixed to the output end of the micro motor 12. The transverse driving part is installed on the rotating rod 13. A circle of sliding groove 14 is opened inside the nozzle 11. The end of the rotating rod 13 extends into the sliding groove 14 and is slidably connected thereto. The length of the rotating rod 13 is slightly longer than the inner diameter of the nozzle 11.

[0037] like Figure 5 and 6As shown, the transverse driving member includes an electric push rod 15 and a movable plate 16. The electric push rod 15 is fixed on the rotating rod 13. The electric push rod 15 is electrically connected to the control panel in the hook machine 1, and the output end of the electric push rod 15 is fixed on the movable plate 16. The length of the movable plate 16 is smaller than the inner diameter of the nozzle 11. Three rows of through-hole needles 17 are fixed on the movable plate 16. The rotating rod 13 is rotatably connected to a limit rod 24 at the rotation center. The end of the limit rod 24 is fixed on the inner wall of the nozzle 11, and the limit rod 24 is slidably sleeved with a limit sleeve 25, and the limit sleeve 25 is fixedly connected to the movable plate 16.

[0038] like Figure 1-3 As shown, a sleeve 6 is fixed at the turning point of the robot arm 2 through a fixing ring 7, the sleeve 6 is sleeved on the outside of the hose 5, and a plurality of balls 8 are rotatably connected inside the sleeve 6, the balls 8 are rollingly connected to the outer wall of the hose 5, and a plurality of humidity sensors 9 are installed in the sleeve 6 through grooves.

[0039] The working principle of the device is as follows:

[0040] Before the hook machine 1 works, the high-pressure micro-mist device 21 in the installation frame 4 is started by the remote control. A high-pressure water pump is arranged inside the high-pressure micro-mist device 21. The water in the water tank 19 is pumped out and pressurized to a certain pressure by the high-pressure water pump and the connecting pipe 22, and is transported to the three nozzles 11 through the hose 5. Inside the nozzle 11, the high-pressure water flows through atomizing components such as microporous plates, microporous tubes or ceramic spray sheets, and is dispersed into extremely small water mist particles (usually 3-15 microns in diameter). The water mist sprayed by the three nozzles 11 forms a fan-shaped water curtain, which is sprayed above the bucket 3.

[0041] When the excavator 1 is working, the mechanical arm 2 is used to drive the bucket 3 to perform excavation work. A large amount of dust is generated during the excavation process. The fan-shaped water mist sprayed by the three nozzles 11 can efficiently adsorb the dust raised near the bucket 3 on the water droplets, reducing environmental pollution. The spray device (i.e., the water tank 19, the high-pressure micro-mist equipment 21 and the injection assembly) is installed on the excavator 1, so that the excavator 1 can solve the problem of dust reduction by itself during operation, and reduce dust from the source of construction. Compared with the prior art that uses a sprinkler truck or a water pipe to assist in water spraying and dust reduction, the present invention does not require additional manpower to operate the water spraying equipment, saving labor costs. Only a remote control is needed to control the spray device, making the dust reduction operation more convenient. In addition, the fan-shaped water mist formed during the operation can effectively block dust from flying, save water resources and is not easy to produce water accumulation.

[0042] In order to protect the hose 5 at the turning point of the robot arm 2, a sleeve 6 with a ball 8 inside is provided at the turning point of the robot arm 2. Specifically, when the robot arm 2 moves, the hose 5 will be driven to move, and the hose 5 will drive the ball 8 inside the sleeve 6 to roll. The sleeve 6 can effectively protect the hose 5 at the turning point of the robot arm 2 to prevent the hose 5 from being stuck at the turning point of the robot arm 2 or directly contacting the robot arm 2. It should be noted that the length of the hose 5 outside the reel 23 is sufficient for the movement of the robot arm 2 to ensure normal spraying of the spray device. The reel 23 is used to collect excess hose 5 to make the interior of the installation frame 4 tidier.

[0043] Since the hose 5 at the turning point of the robot arm 2 is more worn than the hose 5 at other places, in order for the staff to know whether the hose 5 is leaking in time, multiple humidity sensors 9 are installed in each sleeve 6, and the humidity sensor 9 is electrically connected to the control panel. Before the spray device is used, the humidity sensors 9 in the multiple sleeves 6 first test the humidity in the multiple sleeves 6, and take the average humidity measured by these humidity sensors 9 as the humidity value of the humidity sensor 9 preset in the control panel. For later judgment, when the hose 5 transports water, if the humidity sensor 9 in the sleeve 6 measures the humidity is less than or equal to the humidity value, it means that the hose 5 at the turning point of the robot arm 2 has no leakage; otherwise, it means that there is a leakage, and the humidity sensor 9 will transmit the data to the control panel, and the control panel will promptly remind the staff which specific part of the hose 5 is leaking, so as to take remedial measures in time.

[0044] The micro motor 12 is a variable speed motor. The micro motor 12 can be set to rotate at a low speed or a high speed through the control panel in the hook machine 1. When rotating at a low speed, it can be set to rotate 90° or 180° before stopping. When the spray device is in working state, the rotating rod 13, the moving plate 16 and the through-hole needle 17 are not opposite to the spray hole 18, and the rotating rod 13 is downward under the action of gravity to avoid affecting the normal operation of the spray head 11. If it is necessary to further reduce the water mist particles, the micro motor 12 is started to rotate at a high speed through the control panel. The machine 12 will drive the rotating rod 13 to rotate in the slide groove 14. When the rotating rod 13 rotates, it will drive the electric push rod 15, the movable plate 16 and the through-hole needle 17 to rotate. At this time, the micro motor 12, the rotating rod 13, the electric push rod 15, the movable plate 16 and the through-hole needle 17 are equivalent to a centrifugal fan that crushes water mist particles and centrifugally decomposes water mist particles, which is beneficial for the nozzle 11 to spray smaller water mist particles, improves the spray efficiency, and further facilitates better dust reduction effect. During this process, the limit sleeve 25 rotates on the limit rod 24.

[0045] After the hook machine 1 has finished working, the power of the high-pressure micro-mist device 21 is turned off by using the remote control. Water droplets and dust will adhere to the surface of the nozzle 11, and the dust is very likely to enter the spray hole 18 through the flow of water droplets. When there are no more water droplets flowing on the surface of the nozzle 11 or before the next hook machine 1 works, the micro motor 12 is started to rotate at a low speed through the control panel. When the micro motor 12 drives the rotating rod 13 to rotate 90°, the control panel will turn off the micro motor 12, and at the same time, the electric push rod 15 will be started to drive the moving plate 16 and the through-hole needle 17 to approach the spray hole 18. As the through-hole needle 17 continues to move, it will enter the corresponding spray hole 18, and the spray hole 18 can be through-hole operated. When the spray hole 18 on one side is through-hole, the electric push rod 15 will drive the moving plate 1 6 and the through-hole needle 17 return to their original positions, then the control panel will turn off the electric push rod 15 and start the micro motor 12. When the micro motor 12 drives the rotating rod 13 to rotate 180°, the control panel will turn off the micro motor 12. At this time, the through-hole needle 17 corresponds to the spray hole 18 on the other side. Then the control panel will start the electric push rod 15 to drive the through-hole needle 17 to perform the second through-hole operation. The specific operation will not be repeated. After the through-hole is completed, the electric push rod 15 will drive the moving plate 16 and the through-hole needle 17 to return to their original positions. Finally, the control panel will turn off the electric push rod 15. At this time, the micro motor 12, the rotating rod 13, the electric push rod 15, the moving plate 16 and the through-hole needle 17 are equivalent to the through-hole component to prevent the spray hole 18 from being blocked and affecting the water output, thereby realizing the dual use of the same component.
