[0033] When earthwork construction or loading and unloading of goods such as earth, stone, sand and other goods is required at the construction site, a lot of dust will fly on the site, affecting the health and safety of the construction workers. It is necessary to spray dust reduction at the construction site to prevent the flying dust during the construction process from causing harm to the construction workers and surrounding personnel.

[0034] When spray dust removal is required, first push the cart 1 to move to a suitable dust removal position, then stimulate the pushing mechanism 3 to raise the height of the spray to a suitable position, then stimulate the spray mechanism 4, and through the cooperation of the rotating mechanism 5 and the pushing mechanism 3, continuously rotate and swing during the spraying process to further expand the spraying range of the water mist. At the same time, in the spraying process, cooperate with the rotating mechanism 5 to blow the water mist scattered above the cart 1 to the outside, further increase the combination of water mist and dust, and save water resources;

[0035] At the same time, during the swinging process of the rotating mechanism 5 cooperating with the pushing mechanism 3, the blowing mechanism 6 is triggered, so that part of the structure of the blowing mechanism 6 is continuously pressurized and inflated. When the dust removal is completed, during the resetting process of the spray mechanism 4 driven by the pushing mechanism 3, the high-pressure gas is ejected from the inside of the nozzle 451 through the cooperation with the blowing mechanism 6, and the inside of the nozzle 451 is self-cleaned to avoid dust clogging the nozzle 451 during the spray dust removal process and affecting subsequent use.

[0036] During the operation of this embodiment, through the cooperation of the rotating mechanism 5 and the pushing mechanism 3, the spray mechanism 4 can continuously rotate and swing when spraying water mist, so that the water mist can cover a wider area and is no longer limited to spraying at a fixed angle, thereby effectively increasing the range of water mist spraying, and can better suppress dust, reduce the harm to personnel caused by flying dust in and around the construction site. At the same time, during the swinging process of the rotating mechanism 5 and the pushing mechanism 3, the blowing mechanism 6 will be triggered so that part of its structure is continuously pressurized and inflated. After the dust removal is completed, it can cooperate with the blowing mechanism 6 to spray high-pressure gas from the inside of the nozzle 451, effectively self-clean the inside of the nozzle 451, prevent dust from clogging the nozzle 451 during the spray dust removal process, ensure the smooth flow of the nozzle 451, and reduce the manpower and time costs caused by manual cleaning due to the blockage of the nozzle 451.

[0039] Specifically, when the cart 1 is pushed to a suitable position as a whole, the hydraulic cylinder 31 is activated, and then the output end of the hydraulic cylinder 31 pushes the push plate 32 upward. Furthermore, in the process of the push plate 32 being pushed upward, the push plate 32 will drive the upper end of the telescopic rod 33 and the Y-shaped rod 34 and the lever 321 upward at the same time. At this time, the telescopic rod 33 is stretched. When the Y-shaped rod 34 rises to a suitable height, the operation of the hydraulic cylinder 31 is stopped, and then the Y-shaped rod 34 and the push plate 32 stop rising and stay at a suitable height.

The lower end of the water pump 43 is fixedly connected to the upper end of the push plate 32, and the two water spray rings 45 are respectively fixedly connected to the outer surface of the inclined part of the Y-shaped rod 34.

[0042] When the Y-shaped rod 34 drives the two water spray rings 45 and the plurality of nozzles 451 to be lifted to a suitable height, the water pump 43 is activated, and then the water inside the water storage barrel 41 cooperates with the hose 1 42. The water pump 43 can continuously atomize the water inside the water storage barrel 41 and transport it to the inside of the two water spray rings 45 through the hose 2 44, and then spray the water mist outward through the plurality of nozzles 451.

[0043] See also Figure 3 The rotating mechanism 5 includes a gear three 56 rotatably connected to the upper end of the fixed seat 11, the upper end of the gear three 56 is fixedly connected to the motor 51, the outer surface of the gear three 56 is meshed with a gear one 52, the upper parts of the gear one 52 and the gear three 56 are jointly provided with a gear two 53, the middle part of the upper end of the gear two 53 is fixedly connected to a rotating shaft 54, and the lower part of the outer surface of the rotating shaft 54 ​​is fixedly connected to a dial plate 55.

[0047] Furthermore, when the gear 1 52 and the gear 3 56 are driven to rotate by the output end of the motor 51, the plurality of shift bars 1 521 on the upper end of the gear 1 52 and the plurality of shift bars 2 561 on the upper end of the gear 3 56 are driven to rotate. When the plurality of shift bars 1 521 are respectively in close contact with the outer surface of the gear 2 53, the gear 1 52 drives the plurality of shift bars 1 521 to rotate, and the plurality of shift bars 1 521 will shift the gear 2 53 to rotate 90 degrees, and then the gear 2 53 is driven to rotate 90 degrees clockwise. degrees, which will drive the shaft 54 ​​and the dial plate 55 to rotate in the same direction. When the plurality of first dials 521 rotate to no longer fit tightly against the outer surface of the second gear 53, the second gear 53 will no longer rotate, and then the shaft 54 ​​and the dial plate 55 will not rotate. When the third gear 56 rotates until the plurality of second dials 561 begin to fit tightly against the outer surface of the second gear 53, the plurality of second dials 561 cooperate to drive the second gear 53 to rotate 90 degrees counterclockwise, and then the second gear 53 will cause the shaft 54 ​​and the dial plate 55 to rotate in the same direction.

[0048] When the motor 51 continues to run, it drives the gear 2 53 , the rotating shaft 54 ​​and the shift plate 55 to realize a 90 degree reciprocating rotation left and right.

[0049] Furthermore, when the rotating shaft 54 ​​is driven to rotate back and forth, the telescopic rod 33 will be driven to rotate continuously, and then the Y-shaped rod 34 will be driven to rotate back and forth left and right during the rotation of the telescopic rod 33, which will drive the two water spray rings 45 and a plurality of nozzles 451 to run in the same direction, so that the water mist sprayed from the nozzle 451 can cover a wider range, reduce the dust content in the air, and improve the comfort and environmental quality of the construction site.

[0050] See also Figure 5 The fixing mechanism 2 includes a U-shaped fixing frame 21 fixedly connected to the upper end of the fixing seat 11, and a roller 1 22 is symmetrically rotatably connected to the lower side of the front end of the U-shaped fixing frame 21. The outer surfaces of the two rollers 1 22 are close to each other and are commonly connected to the outer surface of the output end of the motor 51. The upper part of the vertical part of the U-shaped fixing frame 21 away from each other is rotatably connected to a roller 24, and the outer surfaces of the two rollers 24 away from each other are fixedly connected to a fan 23. The outer surfaces of the two rollers 24 are respectively connected to the roller 1 22 on the same side, and the middle part of the vertical part of the U-shaped fixing frame 21 close to each other is commonly connected to the upper end of the motor 51.

[0051] The motor 51 mentioned above drives the two rollers 22 to rotate through the bevel gear transmission group in the prior art. When the motor 51 rotates, the two rollers 22 rotate continuously. At the same time, the two rollers 22 drive the rollers 24 to rotate continuously through the transmission belts in the prior art.

[0052] Furthermore, when the motor 51 drives the Y-shaped rod 34 to reciprocate through the gear 2 53 and the rotating shaft 54, the motor 51 causes the two rollers 1 22 to rotate continuously, and then the two rollers 2 24 are continuously rotated through the transmission belt, further driving the two fans 23 to rotate;

[0053] When the two fans 23 are continuously rotating, the two fans 23 cooperate with each other to guide the water mist scattered above the cart 1 to be blown outward, so that more water mist is combined with dust, etc., to achieve a better dust removal effect and further reduce dust. At the same time, part of the water mist falls on various structures above the cart 1 and the fixed seat 11, and the two fans 23 cooperate with each other to accelerate the evaporation of the water mist and further extend the use time of the equipment.

[0054] See also Figure 6-8 The blowing mechanism 6 includes a fixing plate 61 fixedly connected to the upper end of the fixing seat 11, a U-shaped plate 62 is arranged at the rear end of the fixing plate 61, a rectangular plate 63 is fixedly connected to the middle part of the upper end of the fixing seat 11, and an airbag 1 64 is fixedly connected to the rectangular plate 63 and the U-shaped plate 62 on one side close to each other, a hose 3 65 is fixedly connected to the rear side of the outer surface of the airbag 1 64, an airbag 2 69 is fixedly connected to the end of the hose 3 65 away from the airbag 1 64, an elastic box 66 is fixedly connected to the outer surface of the airbag 2 69, a spherical shell 67 is arranged on the front side of the outer surface of the airbag 2 69, and a hose 4 68 is fixedly connected to the upper end of the spherical shell 67, a spring 612 is fixedly connected to the middle part of the side close to each other of the fixing plate 61 and the U-shaped plate 62, and a guide rail 611 is symmetrically fixedly connected to the rear end of the fixing plate 61 below the spring 612, and the outer surfaces of the two guide rails 611 are slidably connected to the lower end of the U-shaped plate 62.

[0056] Then, during the pushing process of the U-shaped plate 62, the U-shaped plate 62 will squeeze the airbag 1 64 through the fixed cooperation of the rectangular plate 63, and then part of the gas inside the airbag 1 64 will be squeezed into the inner surface of the airbag 2 69 through the inner surface of the hose 3 65, and at the same time, the left and right parts of the U-shaped plate 62 will be compressed;

[0057] Furthermore, when the paddle plate 55 is driven by the rotating shaft 54 ​​to rotate clockwise and no longer squeezes and pushes the U-shaped plate 62, the spring 612 wants to return to its original state, and then drives the U-shaped plate 62 to slide along the outer surfaces of the two guide rails 611 toward the side close to the fixed plate 61.

[0062] The two one-way valves 682 mentioned above are conventional designs in the prior art. By using the two one-way valves 682 in conjunction with the Y-shaped tube 681, water will not enter the Y-shaped tube 681 during the water spraying process of the two water spray rings 45 in conjunction with the plurality of nozzles 451, while the gas inside the Y-shaped tube 681 can enter the two water spray rings 45 through the one-way valve 682 and then be sprayed out from the plurality of nozzles 451.

[0063] Specifically, when the output end of the hydraulic cylinder 31 pushes the push plate 32 upward to drive the lever 321 to adjust the positions of the two water spray rings 45 upward, the lever 321 moves the right side of the cross bar 673 during the rising process, so that the cross bar 673 is rotated 90 degrees, and then the lever 321 continues to be driven by the push plate 32 to move upward. At this time, the cross bar 673 drives the ball stopper 671 to rotate 90 degrees, and then the through hole 672 is rotated to a state of being disconnected from the inner surface of the ball shell 67 and the inner surface of the hose four 68.

[0064] As the two water spray rings 45 cooperate with the plurality of nozzles 451 and the Y-shaped rod 34 to continuously reciprocate left and right, the paddle plate 55 continuously inflates and pressurizes the inner surface of the airbag 2 69 through the U-shaped plate 62 and the airbag 1 64, and at the same time cooperates with the elastic box 66 to limit the airbag 2 69, so that the inner surface of the airbag 2 69 is continuously pressurized and inflated.

[0065] Then, after the dust removal by spraying water mist is finished, the water pump 43 is first turned off, and then the hydraulic cylinder 31 is activated, so that its output end drives the push plate 32, the lever 321, the Y-shaped rod 34 and the two water spray rings 45 to reset downward, and when the lever 321 is lowered until the outer surface of the lever 321 contacts the upper right outer surface of the cross bar 673, the lever 321 is driven to continue to descend, which drives the cross bar 673 to rotate 90 degrees, and then the ball stopper 671 can be rotated 90 degrees, and then the inner surface of the hose 4 68 and the hose 5 692 and the inner surface of the airbag 2 69 are connected through the through hole 672;

[0066] Then, see Fig.10 The high-pressure gas inside the airbag 2 69 enters the inner surface of the Y-shaped tube 681 through the hose 5 692, the through hole 672 and the inner surface of the hose 4 68 respectively, and then through the coordinated setting of the one-way valve 1 682, the high-pressure gas passes through the inside of the water spray ring 45 and is sprayed out through the several nozzles 451 of the spray mechanism 4, thereby realizing self-cleaning of the nozzle 451 and the inside of the water spray ring 45, and avoiding dust from entering the inside of the nozzle 451 during the spray dust removal process, thereby affecting subsequent use.

[0067] Therefore, in this solution, the Y-shaped rod 34 drives the nozzle 451 to reciprocate 90 degrees through the gear 2 53 and the rotating shaft 54, and the dust will spread over a larger range. The reciprocating rotation of the nozzle 451 can ensure that the water mist can evenly cover the dust-generating areas, effectively suppress the flying of dust, improve the dust removal effect, and reduce the risk of respiratory diseases caused by workers inhaling dust. While expanding the spray range, the scattered water mist can be blown to the outside through the roller 24 and the fan 23 to improve the combination of water mist and dust, and accelerate the evaporation of water mist above the device to extend the service life of the equipment. Through the lever 321 and the cross lever 673 and other structures, the airbag 2 69 is sealed during the process of several nozzles 451 rising to prepare for spraying and dust removal. During the spraying process, the lever plate 55 and the airbag 1 64 and other structures can also be used to inflate and pressurize the inside of the airbag 2 69. During the process of several nozzles 451 descending and resetting, the gas is ejected from the inside of the nozzle 451 to achieve self-cleaning of the inside of the nozzle 451, ensuring that the spray function is not affected during subsequent use.

[0068] It should be noted that the specific installation method of the hydraulic cylinder 31 and the motor 51, the circuit connection method and the control method used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.
