DETAILED DESCRIPTION

[0032] The technical solutions of the present application will be described clearly and completely below in combination with the drawings of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. Embodiment one

[0033] Please refer to the drawings of the present application Figure 1 - the drawings of the present application Figure 5The embodiment of the present application provides a kind of site dust treatment equipment for construction engineering, including base 1 and water tank, the top of base 1 is rotatably connected with the connecting frame 2 of U shape, the center of connecting frame 2 is fixedly connected with electric push cylinder one 3, the drive end of electric push cylinder one 3 is fixedly connected with wind tube 4, the inner wall of wind tube 4 is fixedly provided with fan, the mouth of wind tube 4 is equipped with the pipe body 5 of ladder type, the lower surface of pipe body 5 is fixedly connected with water tank by support column, dust fall assembly 6 is installed in the inside of pipe body 5, dust fall assembly 6 includes fixed ring 601, one end of fixed ring 601 is fixedly connected with the inner wall of wind tube 4, the surface of fixed ring 601 is slidably connected with several liquid inlet pipes 602, the end of liquid inlet pipe 602 close to the center of wind tube 4 is equipped with atomizing nozzle 603, and the other end of liquid inlet pipe 602 is rotatably connected with gyro wheel 604, elastic piece one 605 is respectively arranged on the both sides of liquid inlet pipe 602, elastic piece can be steel plate spring, spiral spring, torsion bar spring, rubber spring etc., spiral spring is used in the embodiment, the both ends of elastic piece one 605 are fixedly connected with the outer wall of liquid inlet pipe 602 and the outer wall of fixed ring 601, mobile wheel is respectively fixedly arranged at the bottom four corners of base 1, pipe body 5 includes ring body one 51, ring body two 52 and ring body three 53, the diameter gradually from small to big, annular slope is respectively arranged between ring body one 51 and ring body two 52 and ring body two 52 and ring body three 53, slope is used for gyro wheel 604 to move between ring body one 51 and ring body two 52 or ring body two 52 and ring body three 53.

[0034] Specifically, the connecting frame 2 is rotatably supported by the base 1, and the angle of the air cylinder 4 can be adjusted by rotating the connecting frame 2 to control the dust falling direction. The liquid inlet pipe 602 is used to input atomizing liquid into the atomizing nozzle 603. The electric push cylinder one 3 is used to drive the air cylinder 4 to move along the pipe body 5. When dust falling is needed, the device is moved to the construction site, and the atomizing nozzle 603 sprays mist droplets. The high-power fan sprays mist droplets to a long range, so that the mist droplets combine with the suspended dust particles in the construction site to settle down, achieving the effect of dust falling. The elastic force of the elastic member one 605 applied to the liquid inlet pipe 602 makes the roller 604 tightly abut against the inner wall of the pipe body 5. The air cylinder 4 is driven to move by the operation of the electric push cylinder one 3, and the liquid inlet pipe 602 installed on the fixed ring 601 is driven to move by the movement of the air cylinder 4, so that the roller 604 can move at the inner wall of the ring body one 51, the ring body two 52 and the ring body three 53. When the roller 604 is inside the ring body one 51, the inner wall of the ring body one 51 is relatively short compared with the distance from the center of the air cylinder 4, so that the atomizing nozzle 603 is distributed in a ring shape. When the roller 604 is inside the ring body two 52, the inner wall of the ring body two 52 is relatively long compared with the distance from the center of the air cylinder 4, so that the atomizing nozzle 603 is distributed in a ring shape. When the roller 604 moves to the inside of the ring body three 53, the inner wall of the ring body three 53 is the longest compared with the distance from the center of the air cylinder 4, so that the atomizing nozzle 603 is distributed in the largest ring shape. Therefore, by adjusting the position of the roller 604 in the ring body one 51, the ring body two 52 or the ring body three 53, the atomizing nozzle 603 can be automatically adjusted in three gears, which is convenient for adjusting according to different dust falling ranges, and achieves the effect of reasonable use of water resources.

[0035] Please refer to the accompanying drawings Figure 4 - the accompanying drawings Figure 5 The dust falling assembly 6 further comprises three groups of pipes one 606, pipes two 608 and pipes three 609 with gradually increasing diameters. One end of the pipes one 606 is fixedly connected with the inner wall of the air cylinder 4, and the outer wall of the pipes one 606 is sleeved with a connecting ring 607. The side wall of the connecting ring 607 is fixedly connected with a fixed column 9, and the other end of the fixed column 9 penetrates through the air cylinder 4 and is fixedly connected with the inner wall of the connecting frame 2. One end of the pipes two 608 is fixedly connected with a plurality of T-shaped connecting rods one 617, the other end of the connecting rods one 617 penetrates through the connecting ring 607, and the surface of the connecting rods one 617 is sleeved with an elastic member two 610. One end of the pipes three 609 is fixedly connected with a plurality of T-shaped connecting rods two 611, the other end of the connecting rods two 611 penetrates through the connecting ring 607, and the surface of the connecting rods two 611 is sleeved with an elastic member three 612. The fan is located inside the pipes one 606.

[0036] Specifically, the connecting ring 607 is fixed and supported by the fixed column 9, the connecting rod one 617 is used to support the conduit two 608, the elastic member two 610 is used to apply a pushing force to the conduit two 608, so that one end of the conduit two 608 abuts against the liquid inlet pipe 602, the connecting rod two 611 is used to support the conduit three 609, and the elastic member three 612 is used to apply a pushing force to the conduit three 609, so that one end of the conduit three 609 abuts against the liquid inlet pipe 602. The atomizing nozzle 603 is located inside the ring body one 51, and the dust falling range is small. The wind generated by the fan flows through the conduit one 606, and the wind force is more concentrated through the conduit one 606 with a smaller diameter, so as to adapt to local small-range dust falling. Similarly, when the atomizing nozzle 603 is located inside the ring body two 52, the dust falling range is expanded. At this time, the conduit two 608 is pushed to move and abut against the liquid inlet pipe 602 by the elastic force of the elastic member two 610, so that the flow range of the wind force through the conduit one 606 into the conduit two 608 is expanded, and the wind force is dispersed to be suitable for relatively large-range dust falling operation. Similarly, when the atomizing nozzle 603 is located inside the ring body three 53, the dust falling range is the largest. At this time, the conduit three 609 is pushed to move and abut against the liquid inlet end by the elastic force of the elastic member three 612. At this time, the flow range is further expanded when the wind force through the conduit one 606 into the conduit two 608, and then into the conduit three 609, so that the wind force is dispersed to the largest extent and is suitable for the largest-range dust falling operation. Through the cooperation of the atomizing nozzle 603 and the three groups of conduits, the outflow pressure and range can be automatically adjusted according to the spraying range of the atomizing nozzle 603, so as to meet the dust falling operation in multiple ranges.

[0037] Please refer to the accompanying drawings Figure 11 One end of the pipe body 5 is fixedly provided with a plurality of inclined plates 10 distributed in a ring shape. The inclined plate 10 can also be replaced by a horn-shaped ring plate. The number of the inclined plate 10 is consistent with the number of the atomizing nozzle 603, and the inclined plate 10 is located on the moving track of the roller 604.

[0038] Specifically, when the roller 604 moves above the inclined plate 10 from the conduit three 609, the atomizing nozzle 603 can further move outward, so as to increase the unfolding amplitude of the atomizing nozzle 603 and adapt to large-range dust falling operation, thereby improving the application range of the dust falling assembly 6. Embodiment two

[0039] Please refer to the accompanying drawings Figure 6 -Appendix Figure 9The inlet pipe 602 comprises 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 rotationally connected with an atomizing pipe 6022, one end of the atomizing pipe 6022 is fixedly connected with the atomizing nozzle 603, and the other end of the atomizing pipe 6022 is fixedly connected with an extension rod 6023, one side of the outer cylinder 6021 close to the atomizing nozzle 603 is provided with a rotating opening 6024 for the atomizing nozzle 603 to pass through, and the other side of the outer cylinder 6021 is provided with an opening 6025 for the extension rod 6023 to rotate, the inner wall of the ring body one 51 is fixedly connected with a plurality of annularly distributed limiting blocks one 54, the inner wall of the ring body three 53 is fixedly connected with a plurality of annularly distributed limiting blocks two 55, the inner wall of the ring body two 52 is rotationally connected with a plurality of limiting blocks 56 through torsion spring shafts, and the limiting blocks 56 are kept vertically distributed with the horizontal center of the ring body two 52 through the torsion of the torsion spring shafts.

[0040] Specifically, the impact force applied by the water flow to the atomizing pipe 6022 drives the atomizing pipe 6022 to rotate and tilt, so that the extension rod 6023 is away from the side of the air duct 4 at the bottom end of the outer cylinder 6021, and the atomizing pipe 6022 is rotationally supported by the outer cylinder 6021. When the atomizing nozzle 603 moves inside the ring body one 51, the extension rod 6023 is blocked by the blocking block one 54, so that the extension rod 6023 drives the atomizing pipe 6022 and the atomizing nozzle 603 to rotate as a whole to the center, and after the atomizing nozzle 603 abuts against the upper side of the rotating port 6024, the electric push cylinder one 3 stops running, 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 one 51 to the ring body two 52, the extension rod 6023 is blocked by the blocking plate 56, and stops moving until the extension rod 6023 is perpendicular to the center line of the air duct 4. At this time, the atomizing nozzle 603 sprays horizontally, so that the spraying range of the atomizing nozzle 603 is relatively uniform when it sprays out as a whole. When the atomizing nozzle 603 moves from the ring body two 52 to the ring body three 53, the extension rod 6023 rotates upward under the blocking 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 making the extension rod 6023 rotate upward until it is out of engagement with the blocking plate 56, so that the atomizing nozzle 603 can enter the ring body three 53. When the atomizing nozzle 603 moves from the ring body three 53 to the ring body two 52, the extension rod 6023 can drive the blocking plate 56 to rotate downward, so that the extension rod 6023 passes through the blocking plate 56. When the atomizing nozzle 603 moves to the ring body three 53, the extension rod 6023 is blocked by the blocking block two 55, so that the extension rod 6023 drives the atomizing pipe 6022 and the atomizing nozzle 603 to rotate in the opposite direction, and after the atomizing nozzle 603 abuts against the bottom side of the rotating port 6024, the electric push cylinder one 3 stops running, so that the atomizing nozzle 603 sprays outward, thereby making the overall spraying range of the atomizing nozzle 603 more dispersed, and achieving the effect of automatically adjusting the direction of the atomizing nozzle 603. When the atomizing pipe 6022 is rotated vertically inside the ring body two 52, one end of the connecting rod one 617 abuts against the connecting ring 607 to limit the guide pipe two 608, so that the guide pipe two 608 is at the longest extension distance at this time, and when the outer cylinder 6021 continues to move inside the ring body three 53, the guide pipe two 608 is not driven to move by the elastic force of the elastic member two 610, and the guide pipe three 609 is driven to continue moving by the elastic force of the elastic member three 612 and abuts against the outer cylinder 6021, so that the guide pipe one 606, the guide pipe two 608 and the guide pipe three 609 are arranged in a stepped manner, and the diameter of the air outlet is automatically adjusted.

[0041] Please refer to the accompanying Figure 6The surface of the atomizing pipe 6022 is fixedly provided with a conveying pipe 6026, the other end of the conveying pipe 6026 penetrates the air cylinder 4 and is fixedly connected with an annular pipe 6027, the annular pipe 6027 is sleeved outside the air cylinder 4, the bottom end of the annular pipe 6027 is fixedly provided with a liquid inlet end, the liquid inlet end is connected with the booster pump, the water tank is fixedly arranged on the base 1, the lower surface of the pipe body 5 is fixedly connected with the water tank through the supporting column, the atomizing pipe 6022 is a hard pipe, and the conveying pipe 6026 is a soft pipe.

[0042] Specifically, the booster pump is used for extracting dust-settling liquid in the water tank into the annular pipe 6027, into the atomizing pipe 6022 through the conveying pipe 6026, and finally sprayed out by the atomizing nozzle 603.

[0043] Please refer to the accompanying drawings Figure 5 and the accompanying drawings Figure 10 One end of the guide pipe two 608 and the guide pipe three 609 is respectively provided with a notch 613 in the form of annular distribution, the notch 613 is used for rotating the extension rod 6023 to pass through, the inner side wall of the notch 613 is provided with a receiving groove 614, the receiving groove 614 is slidably connected with a baffle 615, one end of the baffle 615 in the receiving groove 614 is fixedly connected with an elastic member four 616, and the other end of the elastic member four 616 is fixedly installed on the inner side wall of the receiving groove 614.

[0044] Specifically, the notch 613 is used for the atomizing pipe 6022 and the extension rod 6023 to pass through the guide pipe two 608 and the guide pipe three 609 when being blocked from rotating by the blocking plate 56, so as to avoid motion interference, and the baffle 615 is elastically abutted against the outer cylinder body 6021 through the elastic force of the elastic member four 616 and slides with the atomizing pipe 6022 and the extension rod 6023, which helps to reduce the loss of wind power at the notch 613.

[0045] Please refer to the accompanying drawings Figure 1 and the accompanying drawings Figure 6 The inner side wall of the connecting frame 2 is fixedly connected with an elastic member five 7, the other end of the elastic member five 7 is fixedly connected with the outer wall of the annular pipe 6027, the upper surface of the base 1 is rotatably connected with an electric push cylinder two 8, and the driving end of the electric push cylinder two 8 is rotatably connected with the lower side wall of the air cylinder 4.

[0046] Specifically, the elastic member five 7 is used for applying elastic force to the annular pipe 6027, so that the conveying pipe 6026 is elastically taut, and the movement of the roller 604 is not affected by the loose conveying pipe 6026, and the electric push cylinder two 8 is used for rotating the air cylinder 4, so as to adjust the spray angle of the mist droplets.
