Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a dust suppression device for building construction. Background Technology

[0002] Construction refers to the production activities during the implementation phase of a project. It is the process of building various types of buildings, or the process of turning the lines on the design drawings into physical objects at a designated location. During construction, a large amount of dust is generated due to building materials, and dust suppression is generally achieved by spraying.

[0003] Existing technologies, such as Chinese Patent Publication No. CN220656877U, disclose a dust suppression device for construction, including a spray nozzle. A bracket is fixedly connected to the surface of the spray nozzle, and a support frame is also fixedly connected to the surface of the spray nozzle. A support block is fixedly connected to the bottom surface of the support frame, and an adapter is movably connected to the surface of the support block. This invention uses a lifting device to allow the dust suppression device to adjust its angle, thereby improving the dust suppression effect. When the dust suppression device adjusts the angle of the spray nozzle, the motor drives the gear to rotate clockwise, causing the rotating column to rotate clockwise. Because a disc is fixedly connected to the surface of the rotating column, the disc also rotates clockwise. When the disc rotates clockwise, it causes the column to move upward, which in turn pushes the support column upward. The support column is connected to the support frame via the adapter, so the support column pushes the support frame upward, thus allowing the spray nozzle to adjust its angle upward. However, this invention only uses a single spray nozzle for dust suppression. Although the angle can be adjusted, the spray range is still relatively small, resulting in low dust suppression efficiency.

[0004] To address the issue that existing dust suppression devices used in construction sites are not suitable for rapid, large-scale spraying, most existing equipment uses a single spray nozzle, which is not convenient for rapid, large-scale dust suppression. Construction sites are often large, dusty, and densely populated, so there is a greater need for dust suppression measures that can quickly carry out large-scale spraying operations. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing dust suppression devices for construction are not convenient for rapid, large-scale spraying dust suppression, and to propose a dust suppression device for construction.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a dust suppression device for construction, comprising a vehicle body, a water tank, a water pump, a hose, a nozzle, and a dust suppression mechanism. The water tank is fixedly connected to the surface of the vehicle body, the water pump is fixedly installed on the surface of the water tank, the hose is fixedly connected to the surface of the water pump, the nozzle is fixedly connected to the surface of the hose, and the dust suppression mechanism is disposed on the surface of the vehicle body. The dust suppression mechanism includes a motor, which is fixedly installed on the surface of the vehicle body. A worm gear is fixedly connected to the output end of the motor. An inner cavity is formed inside the vehicle body, and a bracket is fixedly connected to the surface of the inner cavity. A bidirectional threaded rod is rotatably connected to the inner wall of the bracket. A worm wheel is fixedly connected to the surface of the bidirectional threaded rod, and the worm wheel meshes with the surface of the worm gear. A movable platform is threadedly connected to the surface of the bidirectional threaded rod. A limit groove is formed on the surface of the vehicle body, and the movable platform is slidably connected to the surface of the limit groove. A rotating shaft is rotatably connected to the surface of the movable platform, and a placement platform is fixedly connected to the surface of the rotating shaft. The nozzle is disposed inside the placement platform.

[0007] Furthermore, the surface of the vehicle body is provided with a sliding groove, and a U-shaped plate is slidably connected to the surface of the sliding groove. A cleaning brush is fixedly connected to the bottom surface of the U-shaped plate. The surface of the vehicle body is provided with a connecting groove, and a gear is rotatably connected to the surface of the connecting groove.

[0008] Furthermore, the limiting groove is connected to the inner cavity, the sliding groove is connected to the inner cavity, the limiting groove and the sliding groove are connected through a connecting groove, and the surfaces of the movable table and the U-shaped plate are fixedly connected with rack one, and the surfaces of rack one and gear one are meshed.

[0009] Furthermore, the number of the water tank, water pump, hose, nozzle, movable platform, limiting groove, rotating shaft, placement platform, slide, U-shaped plate, connecting groove and gear one are all two sets.

[0010] Furthermore, the surface of the placement platform is provided with an adjustment mechanism, the adjustment mechanism including a magnet one, the magnet one being fixedly connected to the surface of the placement platform, and a magnet two being fixedly connected to the surface of the nozzle.

[0011] Furthermore, a second gear is fixedly connected to the surface of the rotating shaft, a slide rod is slidably connected to the inner wall of the movable platform, an adjusting plate is fixedly connected to the surface of the slide rod, a rack is fixedly connected to the surface of the adjusting plate, and the rack and gear are meshed together.

[0012] Furthermore, the surface of the adjustment plate is provided with adjustment holes, the surface of the movable platform is provided with positioning holes, a positioning rod is inserted and connected to the surface of the positioning hole, the positioning rod is slidably connected to the surface of the adjustment hole, and there are multiple adjustment holes that are evenly distributed.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting up a dust suppression mechanism, the motor is started to drive the worm gear to rotate, which in turn drives the bidirectional threaded rod to rotate. This causes two sets of movable platforms to move towards or away from each other along the limiting groove, thereby adjusting the position of the nozzles on the platform. The water pump is started to draw water from the water tank and spray it out through the hose and nozzles for dust suppression. At the same time, under the action of gear one and rack one, the movable platform moves, causing the U-shaped plate to slide in the opposite direction along the slide groove. The cleaning brush is used to sweep the dust on the ground. The motor can be continuously reversed to make the nozzles and cleaning brushes move back and forth alternately, expanding the spraying and sweeping range. By setting up a dust suppression mechanism, the two sets of nozzles and cleaning brushes that move alternately can perform spraying and sweeping operations over a larger area, increasing the efficiency of dust suppression and saving manpower and time, thus effectively improving the convenience of the equipment.

[0015] 2. In this utility model, by setting an adjustment mechanism, the nozzle can be fixed on the placement platform by the magnetic attraction effect of magnet one and magnet two. When it is necessary to change the nozzle angle, first pull out the positioning rod, pull the slide rod to drive the adjustment plate to move, and under the action of gear two and rack two, drive the rotating shaft and the placement platform to rotate. After the nozzle is rotated to the appropriate angle, the positioning rod is reinserted into the positioning hole and the corresponding adjustment hole to fix the adjustment plate, so that gear two and the rotating shaft are fixed accordingly. By setting an adjustment mechanism, the nozzle angle can be conveniently adjusted as needed to meet different dust suppression requirements, thereby effectively improving the applicability of the equipment.

[0024] The specific setup and function of its dust suppression mechanism 6 and adjustment mechanism 7 will be explained below.

[0025] In this implementation scheme: the dust suppression mechanism 6 includes a motor 601, which is fixedly installed on the surface of the vehicle body 1. A worm gear 602 is fixedly connected to the output end of the motor 601. An inner cavity 603 is opened inside the vehicle body 1. A bracket 604 is fixedly connected to the surface of the inner cavity 603. A bidirectional threaded rod 605 is rotatably connected to the inner wall of the bracket 604. A worm wheel 606 is fixedly connected to the surface of the bidirectional threaded rod 605. The worm wheel 606 is meshed with the surface of the worm gear 602.

A placement platform 610 is fixedly connected to the surface of the rotating shaft 609. The nozzle 5 is disposed inside the placement platform 610.

[0026] The effects achieved by the above components are as follows: the starting motor 601 drives the worm gear 602 to rotate, which in turn drives the worm wheel 606 to rotate the bidirectional threaded rod 605, causing the movable table 607 to slide along the limiting groove 608, thereby adjusting the position of the nozzle 5 on the placement table 610. The inner cavity 603 is set to place some components. The bracket 604 is set to cooperate with the worm wheel 606 to limit the bidirectional threaded rod 605, so that it only rotates and does not move axially. The limiting groove 608 is set to prevent the movable table 607 from rotating with the bidirectional threaded rod 605. The rotating shaft 609 is set to facilitate the adjustment of the angle of the nozzle 5. The placement table 610 is set to place the nozzle 5.

[0028] The effects achieved by the above components are as follows: the slide groove 611 is provided to facilitate the movement of the U-shaped plate 612; the U-shaped plate 612 and the cleaning brush 613 are provided to facilitate the cleaning of dust and foreign objects on the ground; the connecting groove 614 is provided to facilitate the rotation of the gear 615 and to facilitate the engagement of the gear 615 and the rack 616.

[0030] The effect achieved by the above components is that when the movable table 607 moves, under the action of gear 615 and rack 616, the U-shaped plate 612 is driven to move in the opposite direction along the slide groove 611.

[0031] Specifically, the number of water tank 2, water pump 3, hose 4, nozzle 5, movable platform 607, limiting groove 608, rotating shaft 609, placement platform 610, sliding groove 611, U-shaped plate 612, connecting groove 614 and gear 615 are all two sets.

[0032] The effects achieved by the above components are as follows: setting up two sets of nozzles 5, movable platform 607, placement platform 610 and U-shaped plate 612 is to increase the spraying and cleaning range and improve dust suppression efficiency.

[0033] Specifically, the surface of the placement platform 610 is provided with an adjustment mechanism 7, which includes a magnet 71, which is fixedly connected to the surface of the placement platform 610, and a magnet 72 is fixedly connected to the surface of the nozzle 5.

[0034] The effect achieved by the above components is that the magnetic attraction of magnet 1 71 and magnet 2 72 makes it easy to put the nozzle 5 into and fix it in the placement platform 610.

[0035] Specifically, a gear 73 is fixedly connected to the surface of the rotating shaft 609, a slide rod 74 is slidably connected to the inner wall of the movable table 607, an adjusting plate 75 is fixedly connected to the surface of the slide rod 74, a rack 76 is fixedly connected to the surface of the adjusting plate 75, and the rack 76 meshes with the surface of the gear 73.

[0036] The effect achieved by the above components is as follows: when the sliding rod 74 is pulled to move the adjusting plate 75, the rack 76 and gear 73 drive the rotating shaft 609 and the placement platform 610 to rotate, thereby adjusting the angle of the nozzle 5. When the adjusting plate 75 is fixed, the rotating shaft 609 and the placement platform 610 are fixed accordingly, preventing the nozzle 5 from moving randomly.

[0037] Specifically, the surface of the adjusting plate 75 is provided with adjusting holes 77, the surface of the movable table 607 is provided with positioning holes 78, a positioning rod 79 is inserted and connected to the surface of the positioning hole 78, the positioning rod 79 is slidably connected to the surface of the adjusting hole 77, and there are multiple adjusting holes 77 that are evenly distributed.

[0038] The effect achieved by the above components is as follows: when the positioning rod 79 is inserted into the positioning hole 78 and the adjustment hole 77, the position of the adjustment plate 75 is fixed. When the positioning rod 79 is pulled out, the adjustment plate 75 can be moved. The multiple adjustment holes 77 are provided so that the adjustment plate 75 can be fixed in multiple positions and the nozzle 5 can be fixed at multiple angles.

[0039] Working principle: By setting up the dust suppression mechanism 6, the motor 601 is started to drive the worm gear 602 to rotate, which in turn drives the worm wheel 606 to rotate the bidirectional threaded rod 605. This causes the two sets of movable platforms 607 to move towards or away from each other along the limiting groove 608, thereby adjusting the position of the nozzles 5 on the placement platform 610. The water pump 3 is started to draw water from the water tank 2, which is then sprayed out through the hose 4 and the nozzles 5 for dust suppression. At the same time, under the action of gear 615 and rack 616, the movable platform 607 moves, causing the U-shaped plate 612 to slide in the opposite direction along the sliding groove 611. The cleaning brush 613 is used to sweep the dust on the ground. The motor 601 can be continuously rotated forward and backward, causing the nozzles 5 and the cleaning brush 613 to move back and forth alternately, expanding the spraying and sweeping range. By setting up the dust suppression mechanism 6, the two sets of nozzles 5 and the cleaning brush 613, which move alternately, can perform spraying and sweeping operations over a larger area, increasing the efficiency of dust suppression and saving manpower and time, thus effectively improving the convenience of the equipment.

[0040] Furthermore, by setting up an adjustment mechanism 7, the nozzle 5 can be fixed on the placement platform 610 using the magnetic attraction effect of magnet 1 71 and magnet 2 72. When it is necessary to change the angle of the nozzle 5, first pull out the positioning rod 79, pull the slide rod 74 to move the adjustment plate 75. Under the action of gear 2 73 and rack 2 76, the rotating shaft 609 and the placement platform 610 are rotated. After the nozzle 5 is rotated to the appropriate angle, the positioning rod 79 is reinserted into the positioning hole 78 and the corresponding adjustment hole 77 to fix the adjustment plate 75, so that gear 2 73 and rotating shaft 609 are fixed accordingly. By setting up the adjustment mechanism 7, the angle of the nozzle 5 can be conveniently adjusted as needed to meet different dust suppression requirements, thus effectively improving the applicability of the equipment.
