Raise dust prevention spraying device for earth excavation

Abstract

The utility model discloses a dust-raising-preventing spraying device for earth excavation. The dust-raising-preventing spraying device comprises an angle control mechanism installed at one end of the upper surface of a dust-raising-preventing spraying vehicle and a water storage tank installed at the other end of the upper surface of the dust-raising-preventing spraying vehicle. When clean water in a water storage tank is sprayed to an earth excavation construction site through a spray head, a driving motor drives a rotating disc to rotate, the rotating disc drives a gear to rotate through a gear block, so that a rotating rod rotates, and the rotating rod drives a spraying strip-shaped pipe at the upper end and the spray head to rotate at an angle; at the moment, the spring structure is in a stretched state, when the rotating disc rotates to the surface without the gear blocks, the mutual meshing force between the gear blocks and the surface of the gear is lost, and the rotating rod is pulled back to rotate in the opposite direction through the reset elastic force of the spring structure till the next gear block rotates to be meshed with the surface of the gear; and the rotating rod rotates leftwards and rightwards in this way, so that the spray head at the upper end swings leftwards and rightwards for spraying.

Description

Technical Field

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

[0002] The dust suppression spraying device for earthwork excavation is an environmentally friendly equipment mainly used in earthwork excavation areas such as construction sites and mines. By installing nozzles at a certain height, water is atomized and evenly sprayed onto the air above or around the work surface to increase air humidity and suppress dust, preventing dust particles from suspending and spreading into the atmosphere, thereby effectively reducing dust pollution at the construction site and protecting the environment and the health of workers.

[0003] In current earthwork excavation operations, dust suppression spraying devices are commonly used to effectively control dust pollution at construction sites. However, most existing dust suppression spraying devices are designed to be fixedly installed on pipelines. This design means that the spraying device can only spray dust at preset fixed locations. Since the spray coverage is difficult to adjust, it is difficult to flexibly adjust the spraying for different construction areas and dust levels during actual use, which has certain limitations. These limitations not only affect the effectiveness of dust suppression spraying but may also lead to resource waste and reduced construction efficiency.

[0004] Therefore, how to improve existing dust suppression spraying devices to make them more adjustable and adaptable has become an important issue in the environmental management of earthwork excavation sites. Utility Model Content

[0005] One objective of this invention is to provide a dust suppression spraying device for earthwork excavation. This invention addresses the problem that most existing dust suppression spraying devices mentioned in the background adopt a design that is fixedly installed on pipelines. This design means that the spraying device can only spray dust suppression at preset fixed locations. Since the spraying coverage is difficult to adjust, it is difficult to flexibly adjust it according to different construction areas and dust levels during actual use, thus presenting certain limitations.

[0006] A dust suppression spraying device for earthwork excavation according to an embodiment of the present utility model includes an angle control mechanism installed at one end of the upper surface of a dust suppression spraying vehicle and a water tank installed at the other end of the upper surface of the dust suppression spraying vehicle. The angle control mechanism includes a rotating disk and a gear. An L-shaped connecting plate is fixedly connected to one end of the upper surface of the dust suppression spraying vehicle. A drive motor is fixedly connected to the lower surface of the L-shaped connecting plate. The output end of the drive motor is driven and connected to the rotating disk. A toothed block is engaged with the side surface of the rotating disk through a number of sets of adjustment mechanisms. A rotating rod is provided on one side of the rotating disk. A gear is fixedly connected to the lower end of the rotating rod. A spraying pipe is installed at the top end of the rotating rod.

[0007] Preferably, the adjustment mechanism includes a toothed groove and a T-shaped locking block. The toothed groove is formed on the side surface of the rotating disk, and the T-shaped locking block is fixedly connected to one side surface of the toothed block. The toothed block is engaged and connected to the inside of the toothed groove by the T-shaped locking block.

[0008] Preferably, a locking cover plate is engaged at the upper end of the tooth groove.

[0009] Preferably, a first fixing rod is fixedly connected to the upper surface of the L-shaped connecting plate, and a second fixing rod is fixedly connected to the side surface of the rotating rod, with a spring structure provided between the first fixing rod and the second fixing rod.

[0010] Preferably, the spray pipeline includes a rigid pipeline, a flexible pipeline, and a spray strip pipe. The spray strip pipe is rotatably connected to the upper end of the dust suppression spray vehicle via a rotating rod, and several sets of nozzles are fixedly connected to the side surface of the spray strip pipe.

[0011] Preferably, a rigid pipe is fixedly connected to the lower end of the side surface of the water storage tank, a flexible pipe is fixedly connected to the end of the rigid pipe, and a telescopic pipe is fixedly installed between the flexible pipe and the spray strip pipe.

[0012] Preferably, the rigid pipe is fixedly connected to the side surface of the water storage tank by a pipe fixing buckle.

[0013] Preferably, the upper surface of the water storage tank is provided with a water inlet.

[0014] The beneficial effects of this utility model are:

[0015] This invention, through its angle control and adjustment mechanisms, sprays clean water from the storage tank onto the earthwork excavation site via nozzles. A drive motor rotates a rotating disc, which in turn rotates a gear via toothed blocks, causing a rotating rod to rotate. This rotating rod then rotates the upper spray strip and nozzles at an angle. During this rotation, the spring structure is stretched. When the rotating disc reaches a surface without toothed blocks, the meshing force between the toothed blocks and the gear surface is lost. The spring structure's restoring force pulls the rotating rod back in the opposite direction until the next toothed block meshes with the gear surface. This process repeats, allowing the rotating rod to rotate. The device rotates left and right, causing the upper nozzles to swing left and right while spraying. To reduce the spray coverage area by decreasing the swing angle, a certain number of toothed blocks are removed from the tooth grooves, reducing the meshing distance between the gears and the toothed blocks, thus reducing the rotation angle of the gears and ultimately decreasing the spray swing angle. To increase the spray coverage area, the number of toothed blocks is increased, increasing the meshing distance between the gears and the toothed blocks. This increases the rotation angle of the gears driven by the rotating disc, ultimately increasing the spray swing angle. This allows for flexible adjustment of the nozzle angle and control of the spray coverage area, thereby improving the efficiency and adaptability of dust suppression spraying.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] refer to Figure 1-4 A dust suppression spraying device for earthwork excavation includes an angle control mechanism 4 installed at one end of the upper surface of a dust suppression spraying vehicle 1 and a water tank 2 installed at the other end of the upper surface of the dust suppression spraying vehicle 1. The angle control mechanism 4 includes a rotating disk 404 and a gear 403. An L-shaped connecting plate 401 is fixedly connected to one end of the upper surface of the dust suppression spraying vehicle 1. A drive motor 402 is fixedly connected to the lower surface of the L-shaped connecting plate 401. The output end of the drive motor 402 is driven by the rotating disk 404. A toothed block 405 is engaged with the side surface of the rotating disk 404 through several sets of adjustment mechanisms 5. The toothed block 405 is engaged with the inside of the tooth groove 501 by a T-shaped locking block 502. The toothed block 405 can be detached at will. By increasing the number of toothed blocks 405, the meshing distance between the rotating disk 404 and the gear 403 is lengthened, thereby increasing the rotation angle of the gear 403 and increasing the spraying range of the nozzle 306. The number of toothed blocks 405 is reduced, shortening the meshing distance between the rotating disk 404 and the gear 403, thereby reducing the rotation angle of the gear 403 and achieving a smaller spray range of the nozzle 306. When installing the toothed blocks 405, the T-shaped locking block 502 is inserted into the tooth groove 501, and then the locking cover plate 503 is locked on the surface of the tooth groove 501 to fix the position of the toothed blocks 405. When disassembling, the locking cover plate 503 is removed to remove the toothed blocks 405 from the inside of the tooth groove 501. A rotating rod 307 is provided on one side of the rotating disk 404. The lower end of the rotating rod 307 is fixedly connected to the gear 403, and the top end of the rotating rod 307 is equipped with a spray pipe 3. By rotating the rotating rod 307 left and right, the upper spray pipe 3 is driven to swing left and right in a circular motion. By increasing or decreasing the number of toothed blocks 405, the swing amplitude of the spray pipe 3 is adjusted, ultimately achieving the purpose of adjusting the spray coverage range of the nozzle 306.

[0024] Example 1: The adjusting mechanism 5 includes a toothed groove 501 and a T-shaped locking block 502. The toothed groove 501 is formed on the side surface of the rotating disk 404. The T-shaped locking block 502 is fixedly connected to one side surface of the toothed block 405. The toothed block 405 is engaged with the inside of the toothed groove 501 by the T-shaped locking block 502. A locking cover plate 503 is engaged with the upper end of the inside of the toothed groove 501. The locking cover plate 503 limits the installation position of the toothed block 405 inside the toothed groove 501, preventing the toothed block 405 from being installed in the groove. Sliding out from inside the tooth groove 501, the upper surface of the L-shaped connecting plate 401 is fixedly connected to a first fixed rod 406, and the side surface of the rotating rod 307 is fixedly connected to a second fixed rod 407. A spring structure 408 is provided between the first fixed rod 406 and the second fixed rod 407. When the gear 403 rotates, the spring structure 408 is stretched. After the gear 403 loses the biting force of the tooth block 405, the spring structure 408 pulls the rotating rod 307 back to rotate, realizing the reciprocating rotation of the rotating rod 307.

[0025] Example 2: The spray pipeline 3 includes a rigid pipeline 301, a flexible pipeline 302, and a spray strip pipe 305. The spray strip pipe 305 is rotatably connected to the upper end of the dust suppression spray vehicle 1 via a rotating rod 307. Several sets of nozzles 306 are fixedly connected to the side surface of the spray strip pipe 305. The rigid pipeline 301 is fixedly connected through the lower end of the side surface of the water tank 2. The flexible pipeline 302 is fixedly connected to the end of the rigid pipeline 301. 2. A flexible connection is made between the spray strip pipe 305 and the rigid pipe 301. A telescopic pipe 303 is fixedly installed between the flexible pipe 302 and the spray strip pipe 305. The pipe will not be stretched and break when the spray strip pipe 305 swings. The rigid pipe 301 is fixedly connected to the side surface of the water storage tank 2 through the pipe fixing buckle 304. A water inlet 201 is opened through the upper surface of the water storage tank 2. Water is injected into the water storage tank 2 through the water inlet 201.

[0026] In use, spray water is injected into the water storage tank 2 through the water inlet 201. Then, according to the area of ​​dust suppression required for spraying at the earthwork excavation site, the corresponding number of toothed blocks 405 are inserted into the toothed grooves 501. After the toothed blocks 405 are installed, the locking cover plate 503 is locked inside the upper end of the toothed grooves 501. After the toothed blocks 405 are installed, the drive motor 402 is started. The drive motor 402 drives the rotating disk 404 to rotate, causing the toothed blocks 405 to rotate accordingly. The toothed blocks 405 and the gear 403 mesh with each other, and the toothed blocks 405 drive the gear 403 to rotate. The gear 403 ultimately drives the rotating rod 307 to rotate, thereby causing the upper spray strip pipe 305 to rotate at an angle. When the toothed blocks 405 and the gear 403 are meshed, the gear 403 rotates clockwise, and the spring knot... When the structure 408 is in a stretched state, and the rotating disk 404 rotates to the side without the toothed block 405, it loses the meshing force between the toothed block 405 and the gear 403. Through the restoring force of the spring structure 408, the rotating rod 307 rotates in the opposite direction until the next toothed block 405 contacts the surface of the gear 403. This process is repeated to make the rotating rod 307 and the upper spray pipe 3 rotate and swing left and right, spraying and reducing dust in the space within the range. When the dust reduction range is small, a certain number of toothed blocks 405 are reduced, thereby reducing the contact distance between the rotating disk 404 and the gear 403. When the dust reduction range is increased, a certain number of toothed blocks 405 are added, thereby increasing the contact distance between the rotating disk 404 and the gear 403, thus increasing the spray range.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
