[0017] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.
[0018] Figures 1-6 This diagram illustrates a structural diagram of a movable spraying apparatus according to an embodiment of this application. Figures 1-6 As shown, the spraying device may include: Flatbed truck 100; The first spraying assembly 200 is mounted on the flatbed 100 and is located at the end of the flatbed 100 in the forward direction. The second spraying assembly 300 is mounted on the flatbed trolley 100 and rotates relative to the flatbed trolley 100. The third spraying component 400 is mounted on the flatbed trolley 100 and rotates relative to the flatbed trolley 100. The third spraying component 400 and the first spraying component 200 are located on the same side.
[0019] In this embodiment, the first spraying component 200 is disposed at the front end of the flatbed 100. The flatbed 100 travels with the end of the first spraying component 200 mounted as the front end. The first spraying component 200 sprays the front of the flatbed 100. The second spraying component 300 sprays the side of the flatbed 100 in the direction of travel. The second spraying component 300 is rotatably disposed on the flatbed 100. When spraying is not required, the second spraying component 300 can be folded and disposed on the side of the flatbed 100. The third spraying component 400 is disposed on the side of the flatbed 100 away from the end of the first spraying component 200, and the third spraying component 400 is on the same side as the second spraying component 300, which facilitates spraying the ground behind the wheels of the flatbed 100. By setting up the first spraying component 200, the second spraying component 300 and the third spraying component 400, the sides, bottom and tires of the flatbed 100 are sprayed to ensure the integrity of the spraying. When spraying is not required, the second spraying component 300 can be folded and set on the side of the flatbed 100, and the third spraying component 400 is set on the side of the flatbed 100 away from the first spraying component 200, saving the floor space of the flatbed 100. Specifically, the flatbed truck 100 is driven by a generator, which is equipped with a generator fuel tank, and the flatbed truck 100 is driven by a driver.
[0020] like Figures 1-2 and Figure 6 As shown, in one embodiment, it further includes: The material storage component 500 is mounted on the flatbed trolley 100 and is connected to the first spraying component 200, the second spraying component 300 and the third spraying component 400 via pipes.
[0021] In this embodiment, asphalt is placed inside the storage component 500 and insulated by the storage component 500 to prevent the asphalt from solidifying inside the storage component 500. It is then transported through pipelines to the first spraying component 200, the second spraying component 300 and the third spraying component 400 for spraying.
[0022] like Figures 1-3 As shown, in one embodiment, it further includes: The first spraying assembly 200 includes: The first slide rail 210 is mounted on the flatbed trolley 100. The first slider 220 is disposed on the first slide rail 210; The first driving component 230 drives the first slider 220 to move along the first slide rail 210; The cable chain 240 has one end mounted on the flatbed 100 and the other end mounted on the first slider 220. The first nozzle assembly 250 is mounted on the first slider 220 and is connected to the material storage assembly 500 via a pipe.
[0023] In this embodiment, the first drive component 230 drives the slider to move along the first slide rail 210, causing the first nozzle component 250 to move accordingly, spraying asphalt laterally onto the ground. The drag chain 240 is used to protect the pipeline. Specifically, the first drive component 230 is preferably a motor, which drives the lead screw to rotate. The first slider 220 is threaded onto the lead screw. Alternatively, other drive components can be used, which only need to drive the first slider 220 to move along the first slide rail 210.
[0024] like Figure 1 and Figure 3 As shown, in one embodiment, The first nozzle assembly 250 includes: Pressure boosting component 251 is connected to the pipeline; A plurality of first nozzles 252 are disposed on the pressurizing member 251.
[0025] In this embodiment, the pressurizing component 251 is a common pressure stabilizing pump, which pressurizes the first nozzle 252 to ensure stable spraying from the first nozzle.
[0026] like Figures 1-2 and Figure 4 As shown, in one embodiment, The second spraying assembly 300 includes: The first guide rail bracket 310 is mounted on the flatbed cart 100; The second guide rail 320 is mounted on the guide rail bracket; The second slider 330 is disposed on the second guide rail 320; The second drive assembly 340 drives the second slider 330 to move along the second guide rail 320; The second nozzle assembly 350 is mounted on the second slider 330 and is connected to the discharge assembly via a pipe.
[0027] In this embodiment, the first guide rail bracket 310 is rotatably mounted on the flatbed 100. When spraying is required, the first guide rail bracket 310 is rotated so that it is vertically mounted on the flatbed 100. The second slider 330 is adjusted to move along the first guide rail by the second drive assembly 340, thereby enabling the second spray head assembly 350 to perform spraying. Specifically, the structures of the second drive assembly 340, the second slider 330, and the second guide rail 320 are the same as those of the first drive assembly 230, the first slider 220, and the first guide rail. The second drive assembly 340 moves the second slider 330 along the second guide rail 320.
[0028] like Figure 4 As shown, in one embodiment, The second nozzle assembly 350 includes: T-pipe 351 is installed on the second slider 330 and is connected to the pipe. Two 6-point pipes 352 are respectively installed on the tee pipe 351; Two second nozzles 353 are respectively installed on the two corresponding six-point pipes 352, and the second nozzles 353 are installed at an angle relative to the six-point pipes 352.
[0029] In this embodiment, a three-way pipe 351 is connected to a six-point pipe 352, thereby enabling two second nozzles 353 to spray asphalt. Both nozzles are equipped with spray cylinders and nozzles, and a stabilizing pump is provided for pressurization to ensure uniform asphalt spraying. The position of the two second nozzles 353 can be adjusted by adjusting the slider of the second drive assembly 340 to expand the spraying range.
[0030] like Figure 4 As shown, in one embodiment, it further includes: The first rotating shaft 360 is located at the end where the first guide rail bracket 310 is connected to the flatbed 100; Encoder 370 is mounted on the first rotating shaft 360.
[0031] In this embodiment, the rotation angle of the first rotating shaft 360 is limited by the encoder 370. Under normal circumstances, when the second nozzle 353 is spraying, the first guide rail bracket 310 is usually perpendicular to the flatbed 100. When the second nozzle 353 is not spraying, the first guide rail bracket 310 is usually in contact with the flatbed 100, thereby saving the floor space of the flatbed 100. Furthermore, the angle of the first guide rail bracket 310 relative to the flatbed trolley 100 can be adjusted in advance to meet the compatibility of the second nozzle 353 during the spraying process and expand the spraying range.
[0032] like Figures 1-2 and Figure 5 As shown, in one embodiment, The third spraying assembly 400 has the same structure as the second spraying assembly 300. The only difference is that the third spraying assembly 400 has a bend 410, which is connected to a pipe.
[0033] In this embodiment, the third spraying component 400 has the same structure as the second spraying component 300, but the third spraying component 400 does not have a three-way pipe 351, but only a bend pipe 410, so only a third nozzle is provided to spray the machine shell behind the wheels of the flatbed 100. Specifically, both the third and second nozzles are angled to facilitate spraying the ground in front of and behind the wheels of the flatbed truck 100, ensuring the integrity of the spraying.
[0034] like Figures 1-5 As shown, in one embodiment, it further includes: Three heating oil pipe joints 600 are respectively located at the connection between the pressurizing component 251 and the pipeline, the connection between the tee pipe 351 and the pipeline, and the connection between the bend pipe 410 and the pipeline.
[0035] In this embodiment, the heating oil pipe joint 600 is used to prevent the asphalt from cooling down after being transported to the heating oil pipe joint 600, which would affect the asphalt spraying. The heating oil pipe joint 600 heats the asphalt, preventing the asphalt from losing temperature during the pipeline transport process.
[0036] like Figures 1-2 and Figure 6 As shown, in one embodiment, The storage assembly 500 includes: Tank 510 is mounted on flatbed truck 100 and stores asphalt inside tank 510; A heat transfer oil pump 520 is installed on one side of the tank 510; Pump body 530, pump body 530 is connected to the pipeline; Level gauge 540 is installed on tank 510.
[0037] In this embodiment, the amount of asphalt in the tank 510 is observed by a level gauge 540. A protective cover is installed on the outside of the level gauge 540 to protect it. A heat transfer oil pump 520 ensures the temperature of the asphalt in the tank 510 to prevent the asphalt from solidifying. The pump body 530 is connected to the pipeline and the asphalt is transported to the first nozzle, the second nozzle 353 and the third nozzle for spraying.
