[0042] Figure 1 It is a structural schematic diagram of an asphalt spraying device provided in an embodiment of the utility model.

[0043] See also Figure 1 The embodiment of the utility model provides an asphalt spraying device, which includes a support assembly 100, a storage tank 200, a moving assembly 300, a spraying assembly 400 and an identification assembly 500. The storage tank 200 is arranged on the support assembly 100, and the storage tank 200 is used to store asphalt emulsion. The storage tank 200 and the support assembly 100 can be fixedly connected or detachably connected. The fixed connection has good stability, and the detachable connection is easy to replace. The specific setting method can be adaptively selected according to the actual situation.

[0044] The mobile component 300 is arranged below the supporting component 100. The mobile component 300 can be specifically configured as a plurality of casters or rollers to meet the mobility requirements of the asphalt spraying device. The mobile component 300 can be adaptively designed according to the prior art, and the embodiment of the utility model does not impose too many restrictions on this.

[0045] Figure 2 It is a schematic diagram of the coordination of the identification component and the spray component provided in the embodiment of the utility model.

[0046] See also Figure 1 The spraying assembly 400 is disposed above the supporting assembly 100 and connected to the storage tank 200. The spraying assembly 400 is used to spray the asphalt emulsion in the storage tank 200 onto the construction road surface. The marking assembly 500 is disposed on the supporting assembly 100. Figure 2 The identification component 500 is used to indicate the spraying range of the spraying component 400 .

[0047] See also Figure 1 and Figure 2It can be understood that the asphalt spraying device provided by the embodiment of the utility model characterizes the spraying range of the spraying component 400 by setting the identification component 500. In this way, during the construction process, the operator and other construction personnel can clearly see the boundary of the spraying area, thereby avoiding repeated spraying or omissions, and ensuring the uniformity and efficiency of the construction. In addition, before the construction process, the operator can pre-estimate the actual spraying position of the spraying component 400 based on the identification component 500 to facilitate the selection of the initial spraying position, which can reduce the difficulty of using the asphalt spraying device and reduce the degree of dependence of the asphalt spraying operation on manual experience and the requirements for the professional skills of the operator.

[0048] Continue reading Figure 1 In an optional embodiment of the utility model, the spray assembly 400 includes a connecting pipe 410, a pump 430 and a rotating component 440. The connecting pipe 410 is connected to the storage tank 200. A nozzle 420 is provided at one end of the connecting pipe 410 away from the storage tank 200, and the nozzle 420 is arranged toward the construction road surface; the pump 430 is arranged on the connecting pipe 410, and the pump 430 is used to pump the asphalt emulsion in the storage tank 200 to the nozzle 420 and provide sufficient spraying force for the asphalt emulsion; the rotating component 440 is connected to the nozzle 420, and the rotating component 440 is used to drive the nozzle 420 to swing back and forth.

[0049] See also Figure 1 It can be understood that the spray assembly 400 provided in the embodiment of the utility model drives the spray head 420 to swing back and forth by setting a rotating part 440. In this way, during the construction operation, automatic swinging spraying of asphalt emulsion can be achieved. Compared with the prior art, one person pushes the device body by hand, and one person holds the spray rod in the spray system in front to spray asphalt on the road surface. The asphalt spraying device provided in this embodiment can be operated by one person. With the help of a single person directly pushing, rapid asphalt spraying on the road surface can be achieved without the cooperation of two people, which saves labor and improves spraying efficiency.

[0050] In addition, during the asphalt spraying process, the reciprocating swing of the nozzle 420 can help break up the agglomerates that may form in the asphalt emulsion, thereby reducing the risk of clogging the nozzle 420. In addition, the movement of the rotating part 440 also helps to keep the inside of the nozzle 420 clean and prevent asphalt residues from drying and solidifying and clogging the nozzle 420. This design optimizes the continuity and uniformity of asphalt spraying and improves construction efficiency and device reliability.

[0051] In an optional embodiment of the present invention, the pump 430 can be driven by a diesel engine. Of course, a self-driven pump 430 can also be used. Specifically, it can be adaptively selected according to actual conditions.

[0052] Continue reading Figure 1 In an optional embodiment of the utility model, the spray assembly 400 also includes an output pipe 450, which is arranged between the connecting pipe 410 and the nozzle 420. In other words, one end of the output pipe 450 is connected to the connecting pipe 410, and the other end is connected to the nozzle 420. The rotating component 440 is connected to the nozzle 420 through the output pipe 450, and the rotating component 440 is suitable for driving the nozzle 420 to swing back and forth through the output pipe 450. It should be noted that the output pipe 450 is a hard pipe and the connecting pipe 410 is a hose. In this way, on the one hand, the swinging motion of the nozzle 420 can be guaranteed, and on the other hand, the motion interference between the rotating component 440 and the output pipe 450 can be avoided.

[0053] It is understandable that during the construction process, if it is necessary to replace a nozzle 420 with a different aperture, by setting an output pipe 450, compared to directly connecting the nozzle 420 to the rotating part 440, the spray assembly 400 provided in the embodiment of the utility model only needs to be disassembled once to complete the replacement of the nozzle 420. In this way, the replacement efficiency of the nozzle 420 can be improved, the difficulty of replacing the nozzle 420 can be reduced, and it is more conducive to the maintenance of the nozzle 420.

[0054] Continue reading Figure 1 In an optional embodiment of the utility model, the rotating component 440 further includes a motor 441, a first transmission rod 442, a second transmission rod 444 and a rotating support shaft 443. The motor 441 is arranged on the supporting assembly 100. The first transmission rod 442 is connected to the output shaft of the motor 441. The first transmission rod 442 is suitable for rotating around the output shaft of the motor 441 under the drive of the motor 441. One end of the rotating support shaft 443 is rotatably connected to the supporting assembly 100, and the other end is rotatably connected to the output pipe 450. The rotating support shaft 443 is used to support the output pipe 450 to reciprocate. One end of the second transmission rod 444 is connected to the first transmission rod 442, and the other end is rotatably connected to the output pipe 450. The second transmission rod 444 is suitable for reciprocating around the rotating support shaft 443 under the drive of the first transmission rod 442.

[0055] See also Figure 1 and Figure 2 It can be understood that the rotating component 440 provided in the embodiment of the utility model uses the motor 441 as the power source, and transmits movement to the nozzle 420 through the first transmission rod 442 and the second transmission rod 444, so that the nozzle 420 reciprocates along a predetermined path. This design helps to simulate the action of manual spraying in a mechanized way, which can improve the efficiency of asphalt spraying while ensuring the consistency of the spraying effect.

[0056] Continue reading Figure 2In an optional embodiment of the utility model, the reciprocating swing angle of the nozzle 420 is a, wherein the value range of a is -60° to +60°. For example, the swing angle a of the nozzle 420 can be -60°, -30°, 0, +30° or +60° (the positive and negative signs here only represent the angular direction of a relative to the center line of the device). It can be understood that limiting the swing angle of the nozzle 420 to the above-mentioned value range can ensure that the swing range of the nozzle 420 is within the optimal working range, thereby ensuring that the asphalt is evenly distributed on the construction road surface and avoiding excessive spraying to non-construction areas.

[0057] Continue reading Figure 1 In an optional embodiment of the utility model, the support assembly 100 includes a support plate 110, an armrest 120 and an anti-collision component 130. The support plate 110 is arranged above the moving assembly 300 and is used to set the storage tank 200 and the spray assembly 400. The armrest 120 is arranged on the support plate 110 and is located on the side of the storage tank 200 away from the spray assembly 400. The anti-collision component 130 is arranged on at least one side of the support plate 110 and is connected to the armrest 120. The anti-collision component 130 is used to protect the storage tank 200 and the spray assembly 400.

[0058] It is understandable that the support assembly 100 provided by the embodiment of the utility model can protect the support assembly 100, the storage tank 200 and the spray assembly 400 from accidental collisions during the operation of the device by providing the anti-collision component 130, thereby reducing device damage and potential safety risks caused by collisions. In addition, the presence of the anti-collision component 130 helps to absorb impact energy, which can reduce the wear and tear on the device caused by direct impact, thereby extending the service life of the device. Furthermore, due to the protective effect of the anti-collision component 130, the number of times the device needs to be maintained and repaired is reduced in daily use, simplifying the maintenance process and reducing the long-term use cost.

[0059] Continue reading Figure 1 In an optional embodiment of the utility model, the anti-collision component 130 includes a first anti-collision rod 131 and a second anti-collision rod 132. The first anti-collision rod 131 is arranged on the first side of the support plate 110 and is connected to the handrail 120. The second anti-collision rod 132 is arranged on the second side of the support plate 110 and is connected to the handrail 120. It can be understood that by setting the first anti-collision rod 131 and the second anti-collision rod 132, the storage tank 200 and the spray assembly 400 can be protected from both sides thereof, thereby improving the safety of the storage tank 200 and the spray assembly 400.

[0060] Continue reading Figure 1In an optional embodiment of the utility model, the identification component includes a first identification member 510, which is arranged on the first anti-collision bar 131 and extends along the first anti-collision bar 131 in a direction away from the second anti-collision bar 132. When the nozzle 420 rotates to the extreme position of the first side of the support plate 110, the length of the first identification member 510 is used to characterize the spraying limit range of the nozzle 420 on the first side.

[0061] It can be understood that, by setting the first identification member 510, the operator can intuitively estimate the spraying range limit when the nozzle 420 is at the extreme position on the first side of the support plate 110 during the spraying process, which can help the operator adjust the actual spraying movement path to ensure the accuracy and uniformity of asphalt spraying; furthermore, the existence of the first identification member 510 allows the operator to clearly see the spraying boundary range of the nozzle 420 on the first side of the support plate 110. Based on this, the operator can better plan the construction path to avoid repeated spraying or missing areas. At the same time, the clear spraying range indication helps other personnel maintain a safe distance to reduce safety accidents caused by unclear vision.

[0062] In addition, the first identification member 510 can also help improve the success rate of the initial spraying, that is, it can improve the efficiency of the entire construction process. Furthermore, in an uneven construction site or a construction site with obstacles, the first identification member 510 can help the operator better judge the spraying trajectory of the nozzle 420 on the first side of the support plate 110 to avoid the asphalt spraying device from colliding with obstacles.

[0063] Continue reading Figure 1 In an optional embodiment of the utility model, the identification component also includes a second identification member 520, which is arranged on the second anti-collision bar 132 and extends along the direction of the second anti-collision bar 132 away from the first anti-collision bar 131. When the nozzle 420 rotates to the extreme position on the second side of the support plate 110, the length of the second identification member 520 is used to characterize the spraying limit range of the nozzle 420 on the second side.

[0064] It can be understood that, by setting the second identification member 520, the operator can intuitively estimate the spraying range limit when the nozzle 420 is at the extreme position on the second side of the support plate 110 during the spraying process, which can help the operator adjust the actual spraying movement path to ensure the accuracy and uniformity of asphalt spraying; furthermore, the existence of the second identification member 520 allows the operator to clearly see the spraying boundary range of the nozzle 420 on the second side of the support plate 110. Based on this, the operator can better plan the construction path to avoid repeated spraying or missing areas. At the same time, the clear spraying range indication helps other personnel maintain a safe distance to reduce safety accidents caused by unclear vision.

[0065] In addition, the second identification member 520 can also help improve the success rate of the initial spraying, that is, it can improve the efficiency of the entire construction process. Furthermore, in an uneven construction site or a construction site with obstacles, the second identification member 520 can help the operator better judge the spraying trajectory of the nozzle 420 on the second side of the support plate 110 to avoid the asphalt spraying device from colliding with obstacles.

[0066] In an optional embodiment of the utility model, the first identification member 510 is rotatably connected to the first anti-collision rod 131. In a non-operating state, the first identification member 510 is adapted to rotate to the side of the first anti-collision rod 131 facing the second anti-collision rod 132. It is understandable that such a setting allows the first identification member 510 to rotate to the inner side of the anti-collision rod in a non-operating state, which can reduce the space occupied by the overall device, so as to facilitate the movement and storage of the device in a small or complex environment. In addition, when the device is transported, the first identification member 510 can be folded up, reducing the possibility of collision with external obstacles during movement, thereby protecting the first identification member 510 from damage and extending its service life.

[0067] In an optional embodiment of the utility model, the second identification member 520 is rotatably connected to the second anti-collision rod 132. In a non-operating state, the second identification member 520 is adapted to rotate to the side of the second anti-collision rod 132 facing the second anti-collision rod 132. It is understandable that such a setting allows the second identification member 520 to rotate to the inner side of the anti-collision rod in a non-operating state, which can reduce the space occupied by the overall device, so as to facilitate the movement and storage of the device in a small or complex environment. In addition, when the device is transported, the second identification member 520 can be folded up, reducing the possibility of collision with external obstacles during movement, thereby protecting the second identification member 520 from damage and extending its service life.

[0068] In an optional embodiment of the utility model, the first identification member 510 is detachably connected to the first anti-collision rod 131. It can be understood that the detachability of the first identification member 510 increases the versatility of the device. When the identification function is not needed, the first identification member 510 can be easily removed to reduce the volume and weight of the device during transportation or storage, thereby improving the portability and storage efficiency of the device. In addition, when the device is not in operation or during transportation, the first identification member 510 can be removed to avoid damage due to collision or extrusion, thereby protecting the overall integrity and function of the device.

[0069] In addition, the detachable design of the first identification member 510 makes maintenance and replacement simple and quick. If the first identification member 510 is damaged or worn, the operator can easily remove and replace it without disassembling the entire device, thereby reducing maintenance costs and time. In addition, the detachable first identification member 510 allows the operator to adjust it according to the specific construction environment or personal preference, for example, replacing it with a first identification member 510 of a different length or material to adapt to a wider or narrower spraying range, or improving the visibility of the identification by changing the color or material of the first identification member 510.

[0070] In an optional embodiment of the utility model, the second identification member 520 is detachably connected to the second anti-collision rod 132. It can be understood that the detachability of the second identification member 520 increases the versatility of the device. When the identification function is not needed, the second identification member 520 can be easily removed to reduce the volume and weight of the device during transportation or storage, thereby improving the portability and storage efficiency of the device. In addition, when the device is not in operation or during transportation, the second identification member 520 can be removed to avoid damage due to collision or extrusion, thereby protecting the overall integrity and function of the device.

[0071] In addition, the detachable design of the second identification member 520 makes maintenance and replacement simple and quick. If the second identification member 520 is damaged or worn, the operator can easily remove and replace it without disassembling the entire device, reducing maintenance costs and time. In addition, the detachable second identification member 520 allows the operator to adjust it according to the specific construction environment or personal preference, for example, replacing it with a second identification member 520 of different length or material to adapt to a wider or narrower spraying range, or improving the visibility of the identification by changing the color or material of the second identification member 520.

[0072] The working principle of the asphalt spraying device provided by the utility model is shown below:

[0073] The pump 430 is started to extract the asphalt emulsion stored in the storage tank 200, and pump it to the nozzle 420 through the connecting pipe 410 and the output pipe 450. Finally, the asphalt emulsion is sprayed on the ground in the form of mist from the nozzle 420. During this process, the motor 441 drives the first transmission rod 442 to rotate, and the first transmission rod 442 then drives the second transmission rod 444 to drive the output pipe 450 to swing back and forth around the rotating support shaft 443, thereby realizing large-area asphalt spraying on the construction road surface.
