DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0022] Please see the attached Figure 1 -Attached Figure 5The embodiment of the present invention provides a dust reduction treatment equipment for construction engineering sites, including a base 1 and a water tank, the top of the base 1 is rotatably connected to a U-shaped connecting frame 2, the center of the connecting frame 2 is fixedly connected to an electric push cylinder 3, the driving end of the electric push cylinder 3 is fixedly connected to a wind tube 4, the inner wall of the wind tube 4 is fixedly provided with a fan, the tube mouth of the wind tube 4 is sleeved with a stepped pipe body 5, the lower surface of the pipe body 5 is fixedly connected to the water tank through a supporting column, a dust reduction component 6 is installed inside the pipe body 5, the dust reduction component 6 includes a fixing ring 601, one end of the fixing ring 601 is fixedly connected to the inner wall of the wind tube 4, a plurality of liquid inlet pipes 602 are slidably connected to the surface of the fixing ring 601, and an atomizing nozzle 603 is provided at one end of the liquid inlet pipe 602 near the center of the wind tube 4, and The other end of the liquid inlet pipe 602 is rotatably connected to a roller 604, and elastic members 605 are respectively provided on both sides of the liquid inlet pipe 602. The elastic members can be leaf springs, coil springs, torsion bar springs, rubber springs, etc. In this embodiment, a coil spring is used, and the two ends of the elastic member 605 are respectively fixedly connected to the outer wall of the liquid inlet pipe 602 and the outer wall of the fixed ring 601. Moving wheels are respectively fixedly provided at the four corners of the bottom of the base 1. The tube body 5 includes a ring body 1 51, a ring body 2 52 and a ring body 3 53 with diameters gradually increasing from small to large. Annular slopes are respectively provided between the ring body 1 51 and the ring body 2 52 and between the ring body 2 52 and the ring body 3 53. The slopes are used for allowing the roller 604 to move between the ring body 1 51 and the ring body 2 52 or the ring body 2 52 and the ring body 3 53.

[0023] Specifically, the base 1 is used to support the connecting frame 2 for rotation, and the angle of the wind tube 4 can be adjusted to control the dust reduction direction by rotating the connecting frame 2. The liquid inlet pipe 602 is used to input atomized liquid into the atomizing nozzle 603, and the electric push cylinder 3 is used to drive the wind tube 4 to move along the tube body 5. When dust reduction is needed, the device is moved to the construction site, and the mist droplets are sprayed through the atomizing nozzle 603. The long-range mist droplets are sprayed through the high-power fan, so that the mist droplets are combined with the suspended dust particles at the construction site and settled to achieve the effect of dust reduction. The elastic force applied to the liquid inlet pipe 602 by the elastic member 605 is made to make the roller 604 tightly press against the inner wall of the tube body 5. The operation of the electric push cylinder 3 drives the wind tube 4 to move, and the movement of the wind tube 4 drives the liquid inlet pipe 602 installed on the fixed ring 601 to move, so that the roller 604 can move between the ring body 1 51, the ring body 2 52 and The roller 604 moves along the inner wall of the ring body 3 53, and when the roller 604 is inside the ring body 1 51, the inner wall of the ring body 1 51 is shorter than the distance to the center of the wind tube 4, so that the atomizing nozzle 603 is distributed in a circular contraction as a whole. When the roller 604 is inside the ring body 2 52, the inner wall of the ring body 2 52 is longer than the distance to the center of the wind tube 4. At this time, the atomizing nozzle 603 is distributed in a circular expansion as a whole. When the roller 604 moves to the inside of the ring body 3 53, the distance between the inner wall of the ring body 3 53 and the center of the wind tube 4 is the longest. At this time, the overall expansion range of the atomizing nozzle 603 is the largest. Therefore, by adjusting the position of the roller 604 at the ring body 1 51, the ring body 2 52 or the ring body 3 53, the overall expansion range of the atomizing nozzle 603 can be automatically adjusted in three gears, which is convenient for adjustment according to different dust reduction ranges to achieve the effect of rational use of water resources.

[0024] Please see the attached Figure 4 -Attached Figure 5 The dust reduction component 6 also includes three groups of gradually increasing diameters of duct one 606, duct two 608 and duct three 609. One end of the duct one 606 is fixedly connected to the inner wall of the wind tube 4, and the outer wall of the duct one 606 is provided with a connecting ring 607. The side wall of the connecting ring 607 is fixedly connected with a fixing column 9. The other end of the fixing column 9 passes through the wind tube 4 and is fixedly connected to the inner wall of the connecting frame 2. One end of the duct two 608 is fixedly connected to a plurality of T-shaped connecting rods 1 617. The other end of the connecting rod 1 617 passes through the connecting ring 607, and the surface of the connecting rod 1 617 is provided with an elastic part 2 610. One end of the duct three 609 is fixedly connected to a plurality of T-shaped connecting rods 2 611. The other end of the connecting rod 2 611 passes through the connecting ring 607, and the surface of the connecting rod 2 611 is provided with an elastic part 3 612. The fan is located inside the duct one 606.

[0025] Specifically, the connecting ring 607 is fixedly supported by the fixing column 9, the connecting rod 1 617 is used to support the conduit 2 608, the elastic member 2 610 is used to apply a thrust to the conduit 2 608 so that one end thereof is against the liquid inlet pipe 602, the connecting rod 2 611 is used to support the conduit 3 609, the elastic member 3 612 is used to apply a thrust to the conduit 3 609 so that one end thereof is against the liquid inlet pipe 602, the atomizing nozzle 603 is located inside the ring body 1 51, and the dust reduction range is small. The wind generated by the fan flows through the conduit 1 606, and the wind force is more concentrated through the conduit 1 606 with a smaller diameter, thereby adapting to local small-scale dust reduction. Similarly, when the atomizing nozzle 603 is located inside the ring body 2 52, the dust reduction range is expanded. At this time, the conduit is pushed by the elastic force of the elastic member 2 610. The second conduit 608 moves against the liquid inlet pipe 602, so that the flow range is expanded when the wind enters the second conduit 608 through the first conduit 606, making the wind dispersion suitable for a relatively large range of dust reduction operations. Similarly, when the atomizing nozzle 603 is located inside the third ring body 53, the dust reduction range is the largest. At this time, the elastic force of the third elastic member 612 pushes the third conduit 609 to move against the liquid inlet end. At this time, the wind enters the second conduit 608 through the first conduit 606, and then enters the third conduit 609 through the second conduit 608. The flow range is further expanded, making the wind dispersion reach the maximum and suitable for the largest range of dust reduction operations. By using the atomizing nozzle 603 in conjunction with the three groups of conduits, the air outlet pressure and range can be automatically adjusted according to the spray range of the atomizing nozzle 603 to meet dust reduction operations in various ranges.

[0026] Please see the attached Figure 11 One end of the tube body 5 is fixed with several annularly distributed inclined plates 10, which can also be replaced by a trumpet-shaped annular plate. The number of inclined plates 10 is consistent with the number of atomizing nozzles 603, and the inclined plates 10 are located on the moving track of the roller 604.

[0027] Specifically, when the roller 604 moves from the conduit three 609 to above the inclined plate 10, the atomizing nozzle 603 can move further outward, thereby increasing the expansion range of the atomizing nozzle 603, adapting to a wide range of dust reduction operations, and improving the applicability of the dust reduction component 6. Example 2

[0028] Please see the attached Figure 6 -Attached Figure 9The liquid inlet pipe 602 includes an outer cylinder 6021. The outer surface of the outer cylinder 6021 is provided with a limiting protrusion. When the limiting protrusion passes through the fixing ring 601, the outer cylinder 6021 can be prevented from rotating. The inner wall of the outer cylinder 6021 is rotatably connected to the atomizing pipe 6022. One end of the atomizing pipe 6022 is fixedly connected to the atomizing nozzle 603, and the other end of the atomizing pipe 6022 is fixedly connected to the extension rod 6023. The outer cylinder 6021 is provided with a side close to the atomizing nozzle 603 for supplying liquid to the atomizing nozzle 603. 03 passes through a rotating opening 6024, and an opening 6025 for the extension rod 6023 to rotate is provided on the other side of the outer cylinder 6021, the inner wall of the ring body 1 51 is fixedly connected with a plurality of blocking blocks 1 54 distributed in a ring shape, the inner wall of the ring body 3 53 is fixedly connected with a plurality of blocking blocks 2 55 distributed in a ring shape, the inner wall of the ring body 2 52 is rotatably connected with a plurality of blocking plates 56 through a torsion spring shaft, and the blocking plates 56 are kept vertically distributed with the horizontal center of the ring body 2 52 by the torsion force of the torsion spring shaft.

[0029] Specifically, the impact force exerted by the water flow on the atomizing tube 6022 drives the atomizing tube 6022 to rotate and tilt, so that the extension rod 6023 presses against the bottom end of the outer cylinder 6021 away from the side of the wind tube 4, and the atomizing tube 6022 is supported by the outer cylinder 6021. When the atomizing nozzle 603 moves inside the ring body 51, the extension rod 6023 is blocked by the blocking block 54, so that the extension rod 6023 drives the atomizing tube 6022 and the atomizing nozzle 603 to rotate toward the center as a whole, and the atomizing nozzle 603 is rotated toward the center. 03 against the upper side of the rotating port 6024, the electric push cylinder 1 3 is stopped, so that the atomizing nozzle 603 sprays inward, thereby making the overall spraying range of the atomizing nozzle 603 more concentrated. When the atomizing nozzle 603 moves from the ring body 1 51 to the inside of the ring body 2 52, the extension rod 6023 is blocked by the blocking plate 56 until the extension rod 6023 rotates vertically compared to the center line of the wind tube 4 and stops moving. At this time, the atomizing nozzle 603 maintains horizontal spraying, so that the spraying range of the atomizing nozzle 603 is relatively uniform when the atomizing nozzle 603 is sprayed as a whole, and the mist is When the atomizing nozzle 603 moves from the second ring body 52 to the third ring body 53, the extension rod 6023 rotates upward under the obstruction of the blocking plate 56, so that the extension rod 6023 rotates upward through the opening 6025 and rotates out of the outer cylinder 6021, thereby causing the extension rod 6023 to rotate upward until it is staggered with the blocking plate 56, so that the atomizing nozzle 603 can enter the interior of the third ring body 53. When the atomizing nozzle 603 moves from the interior of the third ring body 53 to the interior of the second ring body 52, the extension rod 6023 can push the blocking plate 56 to rotate downward, thereby causing the extension rod 6023 to rotate upward until it is staggered with the blocking plate 56, so that the atomizing nozzle 603 can enter the interior of the third ring body 53. When the long rod 6023 passes through the blocking plate 56 and the atomizing nozzle 603 moves to the inside of the ring body three 53, the blocking block two 55 drives the extension rod 6023 to block it, so that the extension rod 6023 drives the atomizing tube 6022 and the atomizing nozzle 603 to rotate in the opposite direction, and stops the operation of the electric push cylinder 1 3 after the atomizing nozzle 603 rests against the bottom side of the rotating mouth 6024, so that the atomizing nozzle 603 sprays outward, thereby making the overall spraying range of the atomizing nozzle 603 more dispersed, thereby achieving the effect of automatically adjusting the direction of the atomizing nozzle 603. When the atomizing tube 6022 is located inside the second ring body 52 and rotates vertically, one end of the connecting rod 1 617 abuts against the connecting ring 607 to limit the second conduit 608, so that the second conduit 608 is at the longest extension distance at this time. When the outer cylinder 6021 continues to move to the inside of the third ring body 53, the second conduit 608 is no longer driven by the elastic force of the second elastic member 610 to move, and the third conduit 609 is driven by the elastic force of the third elastic member 612 to continue to move against the outer cylinder 6021, so that the first conduit 606, the second conduit 608 and the third conduit 609 are extended in a stepped manner, automatically adjusting the diameter at the air outlet.

[0030] Please see the attached Figure 6A delivery pipe 6026 is fixedly provided on the surface of the atomizing tube 6022. The other ends of several delivery pipes 6026 all pass through the air duct 4 and are fixedly connected to a ring-shaped tube 6027. The ring-shaped tube 6027 is sleeved on the outside of the air duct 4. The bottom end of the ring-shaped tube 6027 is fixedly provided with a liquid inlet end, which is connected to the booster pump. The water tank is fixedly provided on the base 1. The lower surface of the tube body 5 is fixedly connected to the water tank through a support column. The atomizing tube 6022 adopts a hard tube and the delivery pipe 6026 adopts a soft tube.

[0031] Specifically, the booster pump is used to pump the dust suppression liquid inside the water tank into the annular pipe 6027 , then into the atomizing pipe 6022 through the delivery pipe 6026 , and finally sprayed out from the atomizing nozzle 603 .

[0032] Please see the attached Figure 5 and attached Figure 10 One end of the second conduit 608 and the third conduit 609 is respectively provided with a ring-shaped notch 613, and the notch 613 is used for the extension rod 6023 to rotate through. The inner wall of the notch 613 is provided with a receiving groove 614, and the interior of the receiving groove 614 is slidably connected to a baffle 615. One end of the baffle 615 located inside the receiving groove 614 is fixedly connected to an elastic member 4 616, and the other end of the elastic member 4 616 is fixedly installed on the inner wall of the receiving groove 614.

[0033] Specifically, the gap 613 is used to allow the atomizing tube 6022 and the extension rod 6023 to pass through the conduit two 608 and the conduit three 609 when they are blocked by the blocking plate 56 for rotation, thereby avoiding motion interference. The baffle 615 elastically presses against the outer cylinder 6021 at one end through the elastic force of the elastic member four 616 and slides as the atomizing tube 6022 and the extension rod 6023 rotate, which helps to reduce the loss of wind force at the gap 613.

[0034] Please see the attached Figure 1 and attached Figure 6 The inner wall of the connecting frame 2 is fixedly connected with an elastic member 5 7, the other end of the elastic member 5 7 is fixedly connected to the outer wall of the annular tube 6027, the upper surface of the base 1 is rotatably connected with an electric push cylinder 2 8, and the driving end of the electric push cylinder 2 8 is rotatably connected to the lower side wall of the wind tube 4.

[0035] Specifically, elastic force is applied to the annular tube 6027 by the elastic member 5 7, so that the delivery tube 6026 remains elastic and taut, thereby preventing the delivery tube 6026 from becoming loose and affecting the movement of the roller 604. The operation of the electric push cylinder 2 8 can drive the air cylinder 4 to rotate, thereby adjusting the spray angle of the droplets.

[0036] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
