[0028] Preferably, a rubber ring is fixedly installed on the side of the air duct away from the filter screen, and a pump body is fixedly installed on the top of the water tank below the air duct. The pump body's suction end is connected to a suction pipe, which is also connected to the water tank. The end of the suction pipe is located deep inside the water tank. The pump body's delivery end is connected to a hose, and the end of the hose away from the pump body passes through the air duct and is connected to an annular pipe. A water filling pipe is connected to the upper left side of the water tank. A hydraulic push rod is hinged to the lower side of the air duct on the side of the pump body, and the end of the hydraulic push rod away from the air duct is hinged to the water tank.

[0029] By adopting the above technical solution, the angle of the air duct can be flexibly adjusted.

[0030] Compared with the prior art, the beneficial effects of the present invention are: the on-site dust suppression device based on construction site can automatically absorb water droplets on the nozzle after the spraying operation ends. After absorption, it can prevent water droplets from adhering to the nozzle, and prevent water stains from being left on the nozzle after water evaporation, which would cause concentrated salt to adhere to the nozzle and cause corrosion, thus extending the service life of the nozzle. After cleaning, the water absorption plate can be squeezed to avoid high water content on the water absorption plate affecting subsequent cleaning work. At the same time, after the dust suppression operation is completed, the nozzle can be isolated from the surrounding environment to protect the nozzle and prevent dust and impurities from adhering.

[0031] 1. When dust suppression spraying is required at a construction site, the left end of the air duct is lifted using a hydraulic push rod. The air duct rotates on the support frame, and the lifting of the air duct causes the arc-shaped frame to move circumferentially. This movement, in turn, drives the rotating rod to rotate through the meshing of the teeth and rotating gears. Then, the meshing of the first and second bevel gears drives the rotating shaft to rotate. The rotation of the rotating shaft, through the connection of the first and second pulleys, causes the rotating shaft to rotate clockwise, thus rotating the rotating frame. The rotation of the rotating frame causes the fixed seat to shift away from one end of the air duct, and the fixed seat rotates synchronously during the lifting of the air duct. The air duct, through the arc-shaped frame, drives the fixed seat to rotate. Even with a small rotation of the air duct, it can still cause a large rotation of the fixed seat, causing the rubber ring to deform during the lifting of the air duct, preventing friction and collision between the air duct and the fixed seat. Afterwards, the fan and pump are started. The water pumping pipe draws water from the water tank, and the water flow enters the annular pipe through the hose, causing the nozzles to spray water mist for dust suppression. After the spraying operation ends, the hydraulic push rod resets the air duct, bringing it to a horizontal position. At this time, the mounting base resets, and the water suction plate can absorb and clean the water droplets adhering to the nozzles, allowing for nozzle wiping. The water suction plate can be made of a highly absorbent material such as natural sponge. After the air duct resets, the mounting base can always cover the outside of several nozzles, isolating them from the surrounding environment. This allows for automatic absorption of water droplets from the nozzles after the spraying operation ends, preventing water droplets from adhering to the nozzles and avoiding water stains left after evaporation, which could lead to concentrated salts adhering to the nozzles, causing corrosion and extending the service life of the nozzles.

[0032] 2. After the dust suppression spraying operation is completed, the residual moisture on the nozzle can be absorbed. After absorption, the air duct can be raised again. After raising, the fixed base can be rotated to one side of the limiting plate, so that the water suction plate is aligned with the limiting plate. When the rotating frame is rotated to one side of the limiting plate, the ball bearings on the mounting base can rotate on the ramp of the push block. As the water suction plate and the limiting plate are aligned, the circular plate can be moved by the push block, so that the movable rod can slide on the fixed base, thereby moving the pressure plate. Through the pressure plate and the limiting plate, the water suction plate can be squeezed out, thereby avoiding the water suction plate having a high water content and avoiding affecting subsequent use.

[0033] 3. The water tank is easily moved using rollers. After the water tank is moved, the operator can turn the handle to rotate the limiting rod half a turn, causing the upper limit block of the limiting rod to disengage from the lower limiting groove inside the upper waist-shaped groove. Then, pull the limiting rod to disengage it from the upper waist-shaped groove. Next, the operator can step on the pedal to move the moving rod downwards, allowing the insertion rod to be inserted into the ground. Continuing to move the moving rod downwards causes the movable block to slide in the movable groove and stretch the return spring. As the moving rod moves, the limiting rod aligns with the lower waist-shaped groove. The limiting rod can then be inserted into the lower waist-shaped groove. The operator removes their foot from the pedal, and under the action of the return spring, one end of the limiting rod moves upwards inside the lower waist-shaped groove, causing the limiting block to engage with the upper limiting groove inside the lower waist-shaped groove. This allows the moving rod to be positioned, and the insertion rod can then be used to position the water tank, preventing the water tank from moving during the dust suppression spray process and avoiding changes in the dust suppression area.

[0050] A fixing plate 205 is fixedly installed on one side of the air duct 103, and an arc-shaped frame 206 is fixedly installed at the bottom of the fixing plate 205. Several teeth 209 are fixedly installed on the lower side of one side of the arc-shaped frame 206. Meanwhile, a fixing frame 207 is symmetrically installed on the top of the water tank 1 on one side of the arc-shaped frame 206. A rotating rod 208 is rotatably connected between the two fixing frames 207. A rotating gear 210 is fixedly installed on the outer side of the rotating rod 208, and the rotating gear 210 meshes with several teeth 209.

[0051] A mounting bracket 211 is fixedly installed on one side of the two fixed brackets 207 at the top of the water tank 1. A rotating shaft 212 is rotatably connected to the upper part of the mounting bracket 211. A second bevel gear 213 is fixedly installed at one end of the rotating shaft 212. At the same time, one end of the rotating rod 208 passes through one side of the fixed bracket 207 and is fixedly installed with a first bevel gear 2081. The second bevel gear 2081 meshes with the first bevel gear 213.

[0052] A first pulley 214 is fixedly installed at the end of the rotating shaft 212 away from the second bevel gear 213, and a second pulley 215 is fixedly installed on the outer side of the rotating shaft 201, and the second pulley 215 is rotatably connected to the first pulley 214 via a belt.

[0053] A rubber ring 108 is fixedly installed on the side of the air duct 103 away from the filter screen 104. A pump body 109 is fixedly installed on the top of the water tank 1 below the air duct 103. A water suction pipe 111 is connected through the water suction end of the pump body 109. The water suction pipe 111 is connected through the water tank 1. The end of the water suction pipe 111 is located deep inside the water tank 1. A hose 110 is connected through the water delivery end of the pump body 109. The end of the hose 110 away from the pump body 109 passes through the air duct 103 and is connected through the annular pipe 106. A water filling pipe is connected through the upper left side of the water tank 1. A hydraulic push rod 112 is hinged to the lower side of the air duct 103 on the side of the pump body 109. The end of the hydraulic push rod 112 away from the air duct 103 is hinged to the water tank 1.

[0054] Example 1: As Figures 1-6As shown, when dust suppression spraying is required at a construction site, the left end of the air duct 103 is lifted by the hydraulic push rod 112. The air duct 103 rotates on the support frame 102. After the air duct 103 is lifted, it drives the arc frame 206 to move circumferentially. Then, through the meshing of the teeth 209 and the rotating gear 210, the rotating rod 208 is driven to rotate. Afterwards, through the meshing of the first bevel gear 2081 and the second bevel gear 213, the rotating shaft 212 is driven to rotate. After the rotating shaft 212 rotates, it can drive the first pulley 214 and the second pulley 215 to rotate. The rotating shaft 201 rotates clockwise, causing the rotating frame 202 to rotate. After the rotating frame 202 rotates, the fixed seat 203 is misaligned with one end of the air duct 103. The fixed seat 203 rotates synchronously with the air duct 103 during lifting. The air duct 103 drives the fixed seat 203 to rotate via the arc-shaped frame 206. Even with a small rotation amplitude, the air duct 103 can drive the fixed seat 203 to rotate over a large range, causing the rubber ring 108 to deform during the lifting of the air duct 103. This prevents friction and collision between the air duct 103 and the fixed seat 203 during lifting. The blower 105 and pump body 109 are started, and water is pumped from the water tank 1 through the water suction pipe 111. The water flow can enter the annular pipe 106 through the hose 110, so that the nozzle 107 sprays water mist for dust suppression. After the spraying work is completed, the air duct 103 can be reset by the hydraulic push rod 112, so that the air duct 103 is in a horizontal state. At this time, the fixed base 203 is reset, and the water suction plate 204 can suck up and clean the water droplets attached to the nozzle 107. The nozzle 107 can be wiped, and the water suction plate 204 can also be used to wipe the nozzle 107. Made of a highly absorbent material like natural sponge, the fixing base 203 can always cover the outside of several nozzles 107 after the air duct 103 is reset, isolating the nozzles 107 from the surrounding environment. This allows the air duct 103 to automatically absorb the water droplets on the nozzles 107 after the spraying operation ends, preventing water droplets from adhering to the nozzles 107 and avoiding water stains left on the nozzles 107 after water evaporation, which could lead to concentrated salt adhering to the nozzles 107, thus preventing corrosion of the nozzles 107 and extending their service life.

[0055] The fixed base 203 has symmetrical sliding connections of movable rods 216 inside, and pressure plates 218 are fixedly installed at one end of the two movable rods 216, and circular plates 219 are fixedly installed at the other end of the two movable rods 216. At the same time, telescopic springs 217 are sleeved on one side of the circular plate 219 on the outside of the two movable rods 216, and the two ends of the telescopic springs 217 are fixedly connected to the circular plate 219 and the fixed base 203 respectively.

[0056] A mounting base 220 is fixedly installed on the side of the circular plate 219 away from the fixed base 203, and a ball bearing 221 is hinged to the inside of the mounting base 220. A positioning frame 222 is fixedly installed on the side of the water tank 1 located on the rotating shaft 201. A limiting plate 223 is fixedly installed on the top of the positioning frame 222, and a J-shaped frame 224 is fixedly installed on the top of the limiting plate 223. A push block 225 is fixedly installed on the lower inner side of the J-shaped frame 224, and a ramp is provided on one side of the push block 225.

[0057] Example 2: Figure 2 and Figures 5-7 As shown, after the dust suppression spraying operation is completed, the residual moisture on the nozzle 107 can be absorbed. After absorption, the air duct 103 can be lifted again. After lifting, the fixed base 203 rotates to one side of the limiting plate 223, so that the water suction plate 204 is aligned with the limiting plate 223. When the rotating frame 202 rotates to one side of the limiting plate 223, the ball bearings 221 on the mounting base 220 can rotate on the ramp of the push block 225. As the water suction plate 204 is aligned with the limiting plate 223, the push block 225 can push the circular plate 219 to move, so that the movable rod 216 slides on the fixed base 203, thereby moving the pressure plate 218. Through the pressure plate 218 and the limiting plate 223, the water suction plate 204 can be squeezed, thereby avoiding the water suction plate 204 having a high water content and avoiding affecting subsequent use.

[0058] Positioning components 3 are symmetrically arranged on the left and right sides of water tank 1;

[0059] The positioning component 3 includes mounting plates 301 symmetrically installed on the lower left and right sides of the water tank 1, and a limiting frame 302 is fixedly installed on the lower side of one side of the mounting plate 301. A moving rod 303 is slidably connected inside the limiting frame 302, and an active groove 305 is opened inside the lower part of the moving rod 303.

[0060] The sliding rod 303 is internally slidably connected to a sliding rod 306, and a plug rod 309 is fixedly installed at the bottom end of the sliding rod 306. A return spring 307 is sleeved on the upper part of the sliding rod 306. Meanwhile, a movable block 308 is fixedly installed at the top end of the sliding rod 306, and the movable block 308 is slidably connected to the movable groove 305. The two ends of the return spring 307 are fixedly connected to the movable block 308 and the movable groove 305 respectively.

[0061] A pedal 304 is fixedly installed at the top of the moving rod 303, and a positioning block 310 is fixedly installed on one side of the top of the pedal 304. A limiting rod 311 passes through the inside of the positioning block 310. A handle 312 is fixedly installed at one end of the limiting rod 311. A waist-shaped groove 313 is symmetrically opened on the upper side of one side of the mounting plate 301. The limiting rod 311 is inserted into the waist-shaped groove 313. A limiting groove 314 is fixedly installed on the side of the two waist-shaped grooves 313 that are close to each other. A limiting block 315 is fixedly installed on the outer side of the limiting rod 311. The limiting block 315 is engaged with the limiting groove 314.

[0062] Example 3: Figure 1 and Figures 8-9 As shown, the water tank 1 is easily moved via the roller 101. After the water tank 1 is moved, the operator can rotate the handle 312 to rotate the limiting rod 311 half a turn, causing the upper limit block 315 of the limiting rod 311 to disengage from the lower limiting groove 314 inside the upper waist-shaped groove 313. Then, the operator can pull the limiting rod 311 to disengage from the upper waist-shaped groove 313. After that, the operator can step on the pedal 304 to move the moving rod 303 downward, causing the insertion rod 309 to insert into the ground. Then, the operator can continue to move the moving rod 303 downward, causing the movable block 308 to slide in the movable groove 305 and stretch the return spring 307. The movement of the moving rod 303 aligns the limiting rod 311 with the lower waist-shaped groove 313. Then, the limiting rod 311 can be inserted into the lower waist-shaped groove 313. When the operator's foot leaves the pedal 304, under the action of the return spring 307, one end of the limiting rod 311 moves upward inside the lower waist-shaped groove 313, causing the limiting block 315 to engage with the limiting groove 314 above the lower waist-shaped groove 313. This allows the moving rod 303 to be positioned, and the water tank 1 can be positioned by the insertion rod 309, preventing the water tank 1 from moving during the dust suppression spray process and avoiding changes in the dust suppression area.

[0063] Working principle: When using this on-site dust suppression device based on building construction, firstly, according to... Figures 1-9As shown, when dust suppression spraying is required at a construction site, the left end of the air duct 103 is lifted by the hydraulic push rod 112. The air duct 103 rotates on the support frame 102. After the air duct 103 is lifted, it drives the arc frame 206 to move circumferentially. Then, through the meshing of the teeth 209 and the rotating gear 210, the rotating rod 208 rotates. Afterward, through the meshing of the first bevel gear 2081 and the second bevel gear 213, the rotating shaft 212 rotates. After the rotating shaft 212 rotates, through the connection of the first pulley 214 and the second pulley 215, it can drive the rotating shaft 201 to rotate clockwise, causing the rotating frame 202 to rotate. After the rotating frame 202 rotates, the fixed seat 203 is misaligned with one end of the air duct 103. The fixed seat 203 rotates synchronously during the lifting of the air duct 103. The air duct 103 drives the fixed seat 203 to rotate through the arc frame 206. Even when the rotation amplitude of the air duct 103 is small, it can still drive the fixed seat 203. The large-range rotation causes the rubber ring 108 to deform during the lifting of the air duct 103, preventing friction and collision between the air duct 103 and the fixed seat 203. Then, the fan 105 and pump body 109 are started, and water is pumped from the water tank 1 through the water pipe 111. The water flow can enter the annular pipe 106 through the hose 110, so that the nozzles 107 can spray water mist for dust suppression. After the spraying work is over, the air duct 103 can be reset by the hydraulic push rod 112, so that the air duct 103 is in a horizontal state. At this time, the fixed seat 203 is reset, and the water suction plate 204 can absorb and clean the water droplets attached to the nozzles 107. The nozzles 107 can be wiped, and the water suction plate 204 can be made of a material with good water absorption such as natural sponge. After the air duct 103 is reset, the fixed seat 203 can always cover the outside of several nozzles 107, which can isolate the nozzles 107 from the surrounding environment.

[0064] After the dust suppression spraying operation is completed, the residual moisture on the nozzle 107 can be absorbed. After absorption, the air duct 103 can be raised again. After being raised, the fixed base 203 rotates to one side of the limiting plate 223, so that the water suction plate 204 is aligned with the limiting plate 223. When the rotating frame 202 rotates to one side of the limiting plate 223, the ball bearings 221 on the mounting base 220 can rotate on the ramp of the push block 225. As the water suction plate 204 is aligned with the limiting plate 223, The circular plate 219 can be moved by the pusher 225, causing the movable rod 216 to slide on the fixed seat 203, which in turn moves the pressure plate 218. The pressure plate 218 and the limiting plate 223 can squeeze water out of the water-absorbing plate 204. The roller 101 facilitates the movement of the water tank 1. After the water tank 1 is moved, the operator can turn the handle 312 to drive the limiting rod 311 to rotate half a turn, so that the limiting rod 311 is aligned with the limiting block 315 and the lower part of the upper waist-shaped groove 313. After disengaging from the slot 314, the limiting rod 311 is pulled to disengage from the upper waist-shaped slot 313. Then, the foot pedal 304 is stepped on to move the moving rod 303 downward, causing the insertion rod 309 to insert into the ground. The moving rod 303 continues to move downward, causing the movable block 308 to slide in the movable slot 305 and stretch the return spring 307. As the moving rod 303 moves, the limiting rod 311 aligns with the lower waist-shaped slot 313. The limiting rod 311 can then be inserted into the lower waist-shaped slot 313. The worker's foot leaves the pedal 304, and under the action of the return spring 307, one end of the limiting rod 311 moves upward inside the lower waist-shaped slot 313, causing the limiting block 315 to engage with the upper limiting slot 314 inside the lower waist-shaped slot 313. This allows the moving rod 303 to be positioned, and the insertion rod 309 can then be used to position the water tank 1, preventing the water tank 1 from moving during the dust suppression spray process and avoiding changes in the dust suppression area.
