Therefore, a building construction spray dust reduction device that is easy to adjust and has height adjustment and can rotate and adjust the spray angle is designed. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a building construction spray dust reduction device that is easy to adjust, solving the problems raised in the above background technique.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A building construction spray dust suppression device that is easy to adjust, including a trolley. A water storage tank is fixedly installed on the top of the trolley. A lifting mechanism is arranged on the top of the trolley. A lifting plate is fixedly installed at the top of the lifting mechanism. A rotating platform is rotatably installed on the top of the lifting plate. A spray cylinder is rotatably installed on the surface of the rotating platform. An adjusting device for adjusting the spray angle is arranged on the surface of the lifting plate. The adjusting device includes a motor. The motor is fixedly installed at the bottom of the lifting plate. The output end of the motor is fixedly installed with a turntable. A first tooth block is fixedly installed on the surface of the turntable. A first fixed rod is fixedly installed on the surface of the turntable. A second tooth block is fixedly installed on the surface of the rotating platform. A swing plate is fixedly installed on the surface of the rotating platform.

[0007] According to the above technical solution, the first tooth block meshes with the second tooth block. The water storage tank is communicated with the spray cylinder through a first water pipe, realizing the adjustment of the working height of the equipment and improving the adaptability of the equipment.

[0008] According to the above technical solution, a first sliding groove is opened on the surface of the swing plate. The first fixed rod is slidably connected to the inner wall of the first sliding groove, realizing the multi-angle swinging spray of the spray cylinder, improving the dust suppression effect of the equipment, making the water mist cover a wider area, and ensuring the uniform distribution of the spray. In this way, the construction site can be more comprehensively covered, avoiding that some areas cannot be effectively dust suppressed due to the fixed spray angle, and ensuring a more uniform dust suppression effect.

[0009] According to the above technical solution, an adaptation device adapted to the spray adjustment angle is arranged on the inner wall of the spray cylinder. The adaptation device includes a collar. The collar is slidably installed on the surface of the spray cylinder. An inner collar is fixedly installed on the surface of the collar. A sliding ring is slidably installed on the inner wall of the spray cylinder. A fixed block is fixedly installed on the circumferential surface of the sliding ring. One end of the fixed block away from the sliding ring is rotatably installed with a connecting block. A nozzle is fixedly penetrated through the surface of the connecting block. A linkage rod is rotatably installed on the surface of the nozzle. A rotating shaft is rotatably installed on the circumferential surface of the collar. One end of the rotating shaft away from the collar is fixedly installed with a telescopic sliding plate. One end of the telescopic sliding plate away from the rotating shaft is rotatably installed with a sliding block. A threaded rod is rotatably penetrated through the surface of the sliding block. When the angles of the nozzles are concentrated, the spraying distance also increases accordingly. When the angles of the nozzles diverge, the spraying range increases accordingly, realizing the adaptability of the shooting range and the range of the equipment, so as to carry out the dust suppression work well.

[0010] According to the above technical solution, one end of the telescopic connecting rod away from the rotating table is rotatably installed on the surface of the sleeve ring, one end of the linkage rod away from the nozzle is rotatably connected to the inner sleeve ring, the spray barrel is connected to the sliding ring through water pipe 1, and the sliding ring is connected to the nozzle through water pipe 2, thereby improving the stability of the sliding block when it moves or is stationary.

[0011] According to the above technical solution, a sliding groove 2 is opened on the surface of the rotating table, the sliding block is slidably connected to the bottom of the inner wall of the sliding groove 2, the threaded rod is rotatably connected to the surface of the rotating table, and the inner sleeve ring is slidably connected to the inner wall of the spray barrel, thereby preventing the sliding block from being improperly displaced or shaken during the spray dust reduction process after the angle of the spray barrel is adjusted, thereby reducing the dust reduction accuracy of the spray barrel.

[0012] According to the above technical solution, a cleaning device for preventing and cleaning dust is provided on the surface of the rotating table, and the cleaning device includes a second fixing rod, and the second fixing rod is fixedly installed on the surface of the sliding block, and a dust cover is fixedly installed on the end of the second fixing rod away from the sliding block, and a cleaning plate is fixedly installed on the surface of the dust cover, and a tooth plate one is fixedly installed on the surface of the dust cover, and a tooth plate two is fixedly installed on the surface of the rotating table, and a sliding rod is fixedly installed on the surface of the sliding block, and a brush plate is fixedly installed on the circumferential surface of the sliding rod, so as to brush and clean the surface of the lifting plate, thereby preventing the lifting plate from being in the construction site for a long time to work so that too much impurities and dust accumulate on its surface, which may cause the rotating table to get stuck or cause damage to the equipment during swinging operation.

[0013] According to the above technical solution, bristles are provided on the surface of the cleaning plate, and the brush plate is slidably connected to the surface of the rotating table, driving the dust cover to vibrate to prevent the dust cover from being stuck at the bottom by debris and impurities during cleaning, thereby affecting the working efficiency of the dust cover.

[0014] The present invention provides a construction spray dust suppression device that is easy to adjust. It has the following beneficial effects: (1) The easily adjustable construction spray dust suppression device starts the lifting mechanism, which pushes the lifting plate to move upward. At the same time, the lifting plate moves upward, which drives the spray barrel to move upward, so as to adjust the working height of the equipment, thereby improving the adaptability of the equipment and avoiding the situation in which the equipment cannot operate well due to height problems in a working area with a limited working height, thereby affecting the spray dust suppression effect of the equipment. The swing of the rotating table drives the spray barrel to swing, and then the water storage tank is opened. The water storage tank transports water into the interior of the spray barrel for spray dust removal, thereby realizing multi-angle swing spraying of the spray barrel, improving the spray dust suppression effect of the equipment, and making the water mist cover a wider area, ensuring that the spray is evenly distributed. In this way, the construction site can be covered more comprehensively, avoiding the situation in which some areas cannot be effectively suppressed due to fixed spray angles, and ensuring a more uniform dust suppression effect.

[0015] (2) In the spray dust suppression device for building construction that is easy to adjust, as the linkage rod rotates, one end away from the inner collar rotates. At this time, the rotation of the linkage rod drives the nozzle to rotate. Under the action of the linkage rod, the nozzle rotates towards the direction close to the center of the spray cylinder. When the angles of the nozzles are concentrated, it avoids the dispersion of the sprayed water, resulting in a shortened horizontal distance, and thus increases the spraying distance. When the angles of the nozzles diverge, the spraying range increases accordingly, achieving the adaptability of the shooting range and the spraying range of the device, so as to carry out the dust suppression work well. The sliding block and the threaded rod are connected by threads. The sliding block slides on the circumferential surface of the threaded rod and self-locks, improving the stability of the sliding block when it moves or is stationary, and avoiding improper displacement or shaking of the sliding block during the spray dust suppression process after the angle of the spray cylinder is adjusted, which may lead to a decrease in the dust suppression accuracy of the spray cylinder.

[0016] (3) In the spray dust suppression device for building construction that is easy to adjust, as the second fixed rod moves, the dust-proof cover moves. The movement of the dust-proof cover drives the cleaning plate to move and brush the surface of the lifting plate, avoiding excessive accumulation of impurities and dust on the surface of the lifting plate during long-term operation at the construction site, which may cause jamming during the swinging operation of the rotating table or damage to the device. At the same time, the vibration of the first toothed plate drives the dust-proof cover to vibrate, avoiding the bottom of the dust-proof cover being stuck by sundries and impurities during the cleaning work, which may affect the working efficiency of the dust-proof cover. When the sliding block moves, it drives the sliding rod to move. At the same time, the movement of the sliding rod drives the brush plate to move. At this time, the movement of the brush plate cleans the surface of the rotating table, avoiding the blockage of the gaps of the rotating table by dust or foreign objects, which may affect the normal operation of the rotating table and thus the working efficiency of the device.

When it is necessary to spray and dust a construction area at a specific angle, rotate the electric telescopic rod 77, and the rotation of the electric telescopic rod 77 drives the spray tube 6 to adjust the angle.

[0021] The first tooth block 73 meshes with the second tooth block 75, the water storage tank 2 is communicated with the spray tube 6 through a first water pipe, the swing of the rotating table 5 drives the spray tube 6 to swing, and then the water storage tank 2 is opened, and the water storage tank 2 conveys water into the interior of the spray tube 6 for spray dust reduction.

[0023] During the operation of this embodiment: The staff pushes the equipment to the construction area where dust suppression is required. When there is an obstruction in the dust suppression area, the lifting mechanism 3 is started. The lifting mechanism 3 pushes the lifting plate 4 to move upward. At the same time, the upward movement of the lifting plate 4 drives the spray cylinder 6 to move upward, realizing the adjustment of the working height of the equipment, improving the adaptability of the equipment, and avoiding the situation that the equipment cannot operate well due to height problems in the working area with limited working height, which affects the dust suppression effect of the equipment by spraying. Subsequently, the motor 71 is started. The output end of the motor 71 rotates to drive the turntable 72 to rotate. The rotation of the turntable 72 drives the first fixed rod 74 to rotate around the output end of the motor 71. The rotation of the first fixed rod 74 drives the swing plate 76 to swing. At the same time, the swing of the swing plate 76 drives the rotating platform 5 to swing. The swing of the rotating platform 5 drives the spray cylinder 6 to swing.

In this way, the construction site can be more comprehensively covered, avoiding the situation that some areas cannot be effectively dust suppressed due to the fixed spray angle, ensuring that the dust suppression effect is more uniform. When spray dust removal needs to be carried out on the construction area at a specific angle, the electric telescopic rod 77 is started. The free end of the electric telescopic rod 77 moves to drive the spray cylinder 6 to adjust the angle.

[0024] Please refer to Figures 1 - 8 Based on the above embodiment, in another embodiment of the present invention, an adaptation device adapted according to the spray adjustment angle is provided on the inner wall of the spray cylinder 6. The adaptation device includes a collar 81. The collar 81 is slidably installed on the surface of the spray cylinder 6. An inner collar 82 is fixedly installed on the surface of the collar 81. A sliding ring 83 is slidably installed on the inner wall of the spray cylinder 6. A fixed block 84 is fixedly installed on the circumferential surface of the sliding ring 83. One end of the fixed block 84 away from the sliding ring 83 is rotatably installed with a connecting block 85. A nozzle 86 is fixedly penetrated through the surface of the connecting block 85. A linkage rod 87 is rotatably installed on the surface of the nozzle 86. A rotating shaft 88 is rotatably installed on the circumferential surface of the collar 81. One end of the rotating shaft 88 away from the collar 81 is fixedly installed with a telescopic sliding plate 89. One end of the telescopic sliding plate 89 away from the rotating shaft 88 is rotatably installed with a sliding block 810. A threaded rod 811 is rotatably penetrated through the surface of the sliding block 810. Since the sliding block 810 is threadedly connected with the threaded rod 811, the sliding block 810 slides on the circumferential surface of the threaded rod 811 and is self-locking.

[0025] One end of the electric telescopic rod 77 away from the rotating platform 5 is rotatably installed on the surface of the collar 81. One end of the linkage rod 87 away from the nozzle 86 is rotatably connected to the inner collar 82. The spray cylinder 6 is communicated with the sliding ring 83 through a first water pipe. The sliding ring 83 is communicated with the nozzle 86 through a second water pipe. The movement of the collar 81 drives the inner collar 82 to move. The movement of the inner collar 82 drives one end of the linkage rod 87 away from the nozzle 86 to rotate.

[0026] A sliding groove 2 is provided on the surface of the rotating table 5, the sliding block 810 is slidably connected to the bottom of the inner wall of the sliding groove 2, the threaded rod 811 is rotationally connected to the surface of the rotating table 5, the inner ring 82 is slidably connected to the inner wall of the spray tube 6, and the nozzle 86 rotates toward the center of the spray tube 6 under the action of the linkage rod 87.

[0027] The surface of the rotating table 5 is provided with a cleaning device for preventing and cleaning dust, and the cleaning device includes a fixed rod 91, which is fixedly installed on the surface of the sliding block 810, and a dust cover 92 is fixedly installed on the end of the fixed rod 91 away from the sliding block 810, and a cleaning plate 93 is fixedly installed on the surface of the dust cover 92, and a tooth plate 94 is fixedly installed on the surface of the dust cover 92. A tooth plate 95 is fixedly installed on the surface of the rotating table 5, and a sliding rod 96 is fixedly installed on the surface of the sliding block 810. A brush plate 97 is fixedly installed on the circumferential surface of the sliding rod 96. When the sliding block 810 moves, the sliding rod 96 is driven to move, and at the same time, the movement of the sliding rod 96 drives the brush plate 97 to move.

[0028] The surface of the cleaning plate 93 is provided with bristles, and the brush plate 97 is slidably connected to the surface of the rotating table 5. The movement of the fixed rod 91 drives the dust cover 92 to move, and the movement of the dust cover 92 drives the cleaning plate 93 to move to brush and clean the surface of the lifting plate 4.

[0029] When the present embodiment is working: when the equipment needs to spray dust reduction on a construction area far away and needs to adjust the angle upward, the electric telescopic rod 77 is started to drive the sleeve ring 81 to move, and at the same time, the movement of the sleeve ring 81 drives the spray barrel 6 to rotate with the rotating table 5 as the center of the circle, and the movement of the sleeve ring 81 drives the inner sleeve ring 82 to move, and the movement of the inner sleeve ring 82 drives the end of the linkage rod 87 away from the spray head 86 to rotate, and the rotation of the linkage rod 87 drives the end away from the inner sleeve ring 82 to rotate. At this time, the rotation of the linkage rod 87 drives the spray head 86 to rotate, and the spray head 86 rotates in the direction close to the center of the spray barrel 6 under the action of the linkage rod 87. When the angle of the spray head 86 is concentrated, the spray distance is also increased. When the angle of the spray head 86 is developed When the dust is dispersed, the range of the spray increases accordingly, realizing the adaptability of the range and scope of the equipment, so as to carry out the dust reduction work well. At the same time, when the ring 81 moves, it will drive the rotating shaft 88 to move, and the movement of the rotating shaft 88 will drive the telescopic sliding plate 89 to move, and the movement of the telescopic sliding plate 89 will drive the sliding block 810 to move. Because the sliding block 810 and the threaded rod 811 are connected by threads, the sliding block 810 slides on the circumferential surface of the threaded rod 811 and is self-locking, which improves the stability of the sliding block 810 when it moves or is stationary, and avoids improper displacement or shaking of the sliding block 810 during the spray dust reduction process after the angle of the spray barrel 6 is adjusted, thereby reducing the dust reduction accuracy of the spray barrel 6.

[0030] When the sliding block 810 swings under the action of the rotating table 5, it drives the second fixed rod 91 to move. The movement of the second fixed rod 91 drives the dust-proof cover 92 to move, and the movement of the dust-proof cover 92 drives the cleaning plate 93 to move to brush and clean the surface of the lifting plate 4, avoiding excessive accumulation of impurities and dust on the surface of the lifting plate 4 during long-term operation at the construction site, which may cause jamming during the swinging operation of the rotating table 5 or damage to the equipment. At the same time, when the spray cylinder 6 adjusts its angle, it drives the dust-proof cover 92 to move. The movement of the dust-proof cover 92 drives the first toothed plate 94 to move. The first toothed plate 94 moves closer to and contacts the surface of the second toothed plate 95. At this time, when the first toothed plate 94 moves, it vibrates under the action of the second toothed plate 95. At the same time, the vibration of the first toothed plate 94 drives the dust-proof cover 92 to vibrate, avoiding jamming of the bottom of the dust-proof cover 92 by sundries and impurities during the cleaning work, thereby affecting the working efficiency of the dust-proof cover 92. When the sliding block 810 moves, it drives the sliding rod 96 to move. At the same time, the movement of the sliding rod 96 drives the brush plate 97 to move. At this time, the brush plate 97 moves to clean the surface of the rotating table 5, avoiding blockage of the gaps of the rotating table 5 by dust or foreign objects, thereby affecting the normal operation of the rotating table 5 and further affecting the working efficiency of the equipment.
