DETAILED DESCRIPTION

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] See also Figure 1-7 As shown in the figure, this embodiment provides a construction dust reduction spray device, such as Figure 1 As shown, it includes a mobile cart assembly 1, a first liquid storage barrel 2 is fixedly installed on the top of the mobile cart assembly 1; a first spraying dust reduction mechanism 3 is connected to the top of the first liquid storage barrel 2, a compensation mechanism 4 is fixedly installed on the top of the first liquid storage barrel 2, and a second spraying dust reduction mechanism 5 is fixedly installed on the bottom of the first liquid storage barrel 2; Figure 2 As shown, the first spraying dust reduction mechanism 3 includes an electric suction pipe 31 connected to the top of the first liquid storage barrel 2, one end of the electric suction pipe 31 extending into the inner cavity of the first liquid storage barrel 2 is connected to an auxiliary suction pipe 32, the top of the electric suction pipe 31 is connected to a fluid guide pipe 33, and the outer wall of the fluid guide pipe 33 is connected to a plurality of liquid nozzles 34, and the offset mechanism 4 includes an air storage cylinder 41 fixedly installed on the top of the first liquid storage barrel 2, the top of the air storage cylinder 41 is connected to a gas guide pipe 42, and the outer wall of the gas guide pipe 42 is connected to a plurality of gas nozzles 43.

[0023] Combination Figure 3-4 As shown, the interior of the air cylinder 41 is arranged in a hollow state, and the air cylinder 41 penetrates the top of the first liquid storage barrel 2 and extends into the inner cavity of the first liquid storage barrel 2. The inner cavity of the air cylinder 41 is installed with a piston sealing rod 44 in an up and down sliding state, and the interior of the first liquid storage barrel 2 is provided with a driving component for driving the piston sealing rod 44 to reciprocate up and down.

[0024] Specifically, the first spraying and dust reduction mechanism 3 can extract the liquid inside the first liquid storage barrel 2 and generate water mist for dust reduction, and the offset mechanism 4 is located on one side around the first spraying and dust reduction mechanism 3; when the electric suction pipe 31 is started, the electric suction pipe 31 can extract the liquid inside the first liquid storage barrel 2 through the auxiliary suction pipe 32 and spray it through the liquid nozzle 34 on the fluid guide pipe 33 to form water mist; the gas nozzle 43 can accelerate the water mist generated by the liquid nozzle 34.

[0025] It is understandable that when a large amount of dust is generated during construction, the staff can push the mobile cart assembly 1 to move the present invention to the area where dust reduction operations are required, and then adjust the orientation of the first spraying dust reduction mechanism 3 and the offset mechanism 4 toward the target area, and start the electric suction pipe 31 to suck the liquid in the inner cavity of the first liquid storage barrel 2 and disperse it through multiple liquid nozzles 34 to spray it out to form a water mist group. At the same time, start the offset mechanism 4 to form an airflow through multiple gas nozzles 43 to accelerate the water mist formed by the liquid nozzle 34, which can reduce the impact of external wind on the water mist, so that the water mist can quickly and accurately enter the target area, thereby improving the dust reduction effect.

[0026] Furthermore, the fluid guide tube 33 and the gas guide tube 42 are both arranged in a ring shape, the outer circumferential diameter length of the gas guide tube 42 is greater than the outer circumferential diameter length of the fluid guide tube 33, and the plurality of liquid nozzles 34 are arranged in a ring shape around the outer circumferential surface of the fluid guide tube 33 and are equidistant from each other, and the plurality of gas nozzles 43 are arranged in a ring shape around the outer circumferential surface of the gas guide tube 42 and are equidistant from each other. The purpose of such an arrangement is that when the liquid nozzle 34 sprays water mist, the blowing range of the gas nozzle 43 can be larger than the water outlet range, thereby being able to accelerate the water mist more comprehensively, so that the water mist can enter the target area and improve the dust reduction effect.

[0027] Furthermore, the driving assembly includes a first guide balance ring 45 fixedly mounted on the outer wall of the piston sealing rod 44, and the inner cavity of the first liquid storage barrel 2 is fixedly mounted with a positioning strut 46 which is slidably connected to the first guide balance ring 45. The purpose of this arrangement is that when the piston sealing rod 44 is driven to move up and down, the auxiliary limiting mechanism of the positioning strut 46 can keep the first guide balance ring 45 always in contact with the inner wall of the first liquid storage barrel 2 for up and down reciprocating movement, so that the piston sealing rod 44 always maintains a vertical state for up and down movement.

[0028] Furthermore, the driving assembly further comprises a guide drum 47 rotatably connected to the first liquid storage barrel 2. Figure 2 and Figure 4As shown, a spiral limit slide 48 is fixedly installed on the outer wall of the guide drum 47, and a positioning slide 49 fixedly connected to the first guide balance ring 45 is slidably installed in the inner cavity of the spiral limit slide 48. When the guide drum 47 rotates, it can drive the first guide balance ring 45 to move up and down in the inner cavity of the first liquid storage barrel 2, thereby driving the piston sealing rod 44 to move up and down in the gas storage cylinder 41. The bottom of the piston sealing rod 44 is fixedly installed with a first telescopic spring 410 fixedly connected to the first liquid storage barrel 2, wherein the first guide balance ring 45 is installed on the inner wall of the first liquid storage barrel 2 in an up and down sliding state, and the first guide balance ring 45 is slidably installed on the outer wall of the auxiliary suction pipe 32. The purpose of such a setting is to prevent the first guide balance ring 45 from affecting the suction work of the auxiliary suction pipe 32 on the dust reduction liquid in the inner cavity of the first liquid storage barrel 2 when it moves up and down. At the same time, the bottom of the guide drum 47 is fixedly connected with a stepping motor for driving it to rotate.

[0029] It can be understood that, in actual use, the guide drum 47 is rotated by driving the motor, which can cause the spiral limit slide 48 to rotate synchronously, and then the positioning slide 49 is driven by the spiral limit slide 48 to move up and down, and then drive the first guide balance ring 45 to move back and forth up and down in the inner cavity of the first liquid storage barrel 2, and then drive the piston sealing rod 44 to move back and forth up and down in the air storage cylinder 41, so as to achieve the acceleration of the water mist by the offset mechanism 4.

[0030] Further, refer to Figure 5-7 As shown, the second spraying and dust reduction mechanism 5 includes a second liquid storage barrel 51 fixedly installed at the bottom of the mobile cart assembly 1 and interconnected with the first liquid storage barrel 2, a third liquid storage barrel 52 is installed at the bottom of the second liquid storage barrel 51 in an up and down sliding state, a limiting pressure rod 53 is installed in the inner cavity of the third liquid storage barrel 52 in an up and down sliding state, and a second telescopic spring 54 fixedly connected to the third liquid storage barrel 52 is fixedly installed on the top of the limiting pressure rod 53.

[0031] Specifically, under normal conditions, the second telescopic spring 54 presses the limiting pressure rod 53 to extend downward from the bottom of the third liquid storage barrel 52 as a whole. When the third liquid storage barrel 52 moves downward as a whole and the limiting pressure rod 53 comes into contact with the ground and continues to move downward, the second telescopic spring 54 will be stretched by the force, thereby causing the limiting pressure rod 53 to move as a whole relative to the third liquid storage barrel 52 toward the inside of the third liquid storage barrel 52.

[0032] Furthermore, combined with Figure 4 and Figure 7As shown, a limiting slide groove 55 is provided on the outer wall of the third liquid storage barrel 52, and a connecting sealing plate 56 fixedly connected to the second telescopic spring 54 is slidably installed in the inner cavity of the limiting slide groove 55. Under normal circumstances, the connecting sealing plate 56 is attached to the second liquid storage barrel 51. When the limiting pressure rod 53 moves relative to the third liquid storage barrel 52 toward the inside of the third liquid storage barrel 52, it can synchronously drive the connecting sealing plate 56 to gradually move upward and away from the surface of the second liquid storage barrel 51.

[0033] A plurality of through-holes 57 are provided at the bottom of the second liquid storage barrel 51, and a plurality of sealing limit rods 58 plugged into the flow guide holes 57 are fixedly installed at the bottom of the connecting sealing plate 56. Under normal circumstances, the sealing limit rods 58 are plugged into the inner cavity of the flow guide holes 57, so that the bottom of the second liquid storage barrel 51 remains sealed. When the limiting pressure rod 53 is moved upward as a whole, driving the connecting sealing plate 56 away from the bottom of the second liquid storage barrel 51, the sealing limit rod 58 is pulled out from the inner cavity of the flow guide hole 57, and the bottom of the second liquid storage barrel 51 is communicated with the outside world, so that the dust reduction water in the inner cavity of the second liquid storage barrel 51 can be sprayed onto the ground through the plurality of guide holes 57, thereby performing auxiliary water sprinkling and dust reduction work on the ground.

[0034] Further, refer to Figure 4 As shown, a second guide balance ring 59 is fixedly installed at the bottom of the piston sealing rod 44 , and the second guide balance ring 59 is slidably installed on the outer wall of the positioning support rod 46 , and a support bracket 510 fixedly connected to the third liquid storage barrel 52 is fixedly installed at the bottom of the second guide balance ring 59 .

[0035] It can be understood that in actual use, by moving the piston sealing rod 44 downward, the third liquid storage barrel 52 is pushed downward through the second guide balance ring 59 and the support bracket 510, and when the limiting pressure rod 53 comes into contact with the ground, the limiting pressure rod 53 is forced to move upward by continuously pushing downward, and the multiple sealing limiting rods 58 are pulled out from the inner cavity of the guide hole 57, so that the inner cavity of the second liquid storage barrel 51 is connected to the outside, and the water inside is sprinkled out to reduce dust;

[0036] When the piston sealing rod 44 drives the third liquid storage barrel 52 to move upward as a whole, the elastic restoring force of the second telescopic spring 54 is combined to pull the limiting pressure rod 53 downward as a whole, so that the multiple sealing limiting rods 58 can be plugged into the inner cavity of the guide hole 57 again, and reciprocate in sequence. By combining with the rotating guide drum 47 to drive the piston sealing rod 44 to move up and down, the limiting pressure rod 53 can also move up and down in the inner cavity of the third liquid storage barrel 52, and open and close the bottom of the second liquid storage barrel 51, so that in the process of dust reduction on the ground, intermittent quantitative watering treatment is achieved, and the dust reduction effect at the construction site is further improved.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
