Description

Technical Field

[0001] The invention belongs to the technical field of highway maintenance equipment, and in particular relates to a highway asphalt gravel synchronous sealing robot. Background Art

[0002] Traditional chip seal processes typically involve spraying asphalt first, followed by spreading aggregate. This gap between the two applications can cause the asphalt to cool too quickly, resulting in poor adhesion between the aggregate and the asphalt. The advent of synchronized chip sealers allows for simultaneous asphalt spraying and aggregate spreading, significantly reducing the reaction time between the two.

[0003] With the continuous expansion of highway construction and the increasing quality requirements, intelligent construction has become a trend in the industry. In this context, the introduction of robotic technology into the field of highway asphalt gravel synchronous sealing construction is an inevitable choice. Intelligent robots can automatically complete complex construction tasks through pre-programming or real-time sensor feedback, improving construction efficiency and quality. For example, using advanced sensor technology, robots can perceive the flatness, width and other information of the road surface in real time, and automatically adjust the parameters of asphalt spraying and gravel spreading based on this information to achieve precise construction.

[0004] Existing Chinese patent publication number CN118087335B discloses an asphalt gravel synchronous sealing vehicle, comprising a tractor, an asphalt folding and spreading mechanism, and a gravel evenly distributing and spreading mechanism. The asphalt folding and spreading mechanism is located on top of the tractor, and the gravel evenly distributing and spreading mechanism includes an asphalt transmission mechanism and a spreading adjustment mechanism. The gravel evenly distributing and spreading mechanism includes a gravel transmission mechanism, an evenly distributing mechanism, and an adaptive adjustment mechanism. This invention features an evenly distributing mechanism that, through the movement of an L-shaped telescopic rod, drives two evenly distributing shafts to slide within slots toward the evenly distributing main axis. The evenly distributing spring's uniform force distribution evenly distributes the evenly distributing sliders between the two L-shaped telescopic rods, thus adapting to road surfaces of varying widths. This solves the problem of missed or over-applied gravel caused by varying road widths in conventional technologies, significantly improving the applicability and resource utilization efficiency of the invention.

[0005] However, in the process of spraying asphalt onto the road surface through an asphalt nozzle in the above-mentioned patent, the fixed-angle spraying may result in insufficient asphalt spraying at the edge part or excessive concentration in the middle part. The nozzles of the spraying equipment are usually arranged in a certain straight line and pointed at a fixed angle toward the center of the road surface. Asphalt may not be effectively sprayed on the edge part of the road surface, especially near the shoulder. Such uneven edge coverage may also lead to a poor bonding effect between the gravel and the asphalt. Due to insufficient asphalt at the edge, the gravel cannot obtain sufficient adhesive after spreading and is prone to falling off, thereby reducing the anti-skid performance and durability of the seal layer. Summary of the Invention

[0006] The embodiment of the present invention provides a highway asphalt gravel synchronous sealing robot to solve the problems in the prior art.

[0007] The embodiment of the present invention adopts the following technical solution: a highway asphalt gravel synchronous sealing robot, including a robot body, an asphalt placement bin and a gravel placement bin are provided at the rear of the robot body, and an installation frame is also provided at the rear of the robot body. A gravel distribution mechanism for discharging gravel is provided in the installation frame, and the gravel distribution mechanism is rotatably connected to a position below the installation frame.

The spraying swing mechanism is located on the spraying movement mechanism, and a spraying part connected to the asphalt placement bin is provided on the spraying swing mechanism. A protective cover is provided on the top of the installation frame.

[0008] The present invention drives the spray nozzle to swing left and right through the swing shaft, which can achieve more uniform distribution of asphalt in the width direction of the road, so that the asphalt and gravel are better combined, and the anti-skid performance and durability of the sealing layer are improved.

[0009] Furthermore, a conveying auger is horizontally arranged in the gravel placement bin, a conveying motor transmission-connected to the conveying auger is provided on the side wall of the gravel placement bin, and an inclined conveying channel extending into the installation frame is provided on the side wall of the gravel placement bin.

[0010] Furthermore, the inclined conveying channel is a structure that is small at the top and large at the bottom. The mounting frame is provided with a number of discharge frames arranged at equal intervals, and the plurality of discharge frames are docked with the inclined conveying channel.

[0011] Furthermore, the gravel distribution mechanism includes a drive motor, a drive shaft and several distribution parts arranged at equal intervals in the discharge frame, the drive shaft passes through the several discharge frames and is rotatably connected to the several discharge frames, the drive motor is located on the side wall of the mounting frame and is transmission-connected to the drive shaft, and the distribution parts include four distribution plates arranged at equal intervals on the drive shaft.

[0012] Furthermore, the spraying moving mechanism includes a moving motor, a moving gear and two moving gear plates. The moving motor is located in the installation frame, the moving gear is connected to the main shaft of the moving motor, and the two moving gear plates are symmetrically slidably connected to the bottom position of the installation frame. The moving gear is engaged with the two moving gear plates.

[0013] Furthermore, two spraying swing mechanisms are provided, and the two spraying swing mechanisms are respectively arranged at the bottom positions of the two movable tooth plates.

[0014] Furthermore, each of the spray swing mechanisms includes a mounting frame, a swing motor, a swing plate, a swing shaft and two support plates, the two support plates are symmetrically arranged at the two ends of the bottom of the movable tooth plate, the two ends of the swing shaft are respectively rotatably connected with the two support plates, the mounting frame is located in the middle position of the bottom of the movable tooth plate, the swing plate is connected to the main shaft of the swing motor, two symmetrically fixed connecting plates are provided on the swing shaft, a sliding rod is provided between the two connecting plates, a sliding sleeve is provided on the sliding rod, a sliding column is provided on the sleeve, and the sliding column is slidably fitted with the swing plate.

[0015] Furthermore, there are two spraying parts, each of which includes a delivery pump, a delivery pipe, a connecting pipe, a plurality of spray nozzles and a plurality of mounting seats. The plurality of mounting frames are arranged at equal intervals at the bottom position of the swing shaft, and the plurality of spray nozzles are respectively located on the plurality of mounting seats. The connecting pipe is connected to the plurality of spray nozzles. The delivery pump is located on the robot body and next to the asphalt placement bin. One end of the delivery pipe is connected to the asphalt placement bin and to the delivery pump, and the other end of the delivery pipe extends to be connected to the connecting pipe.

[0016] The at least one technical solution adopted in the embodiment of the present invention can achieve the following beneficial effects:

[0017] First, in the process of spraying asphalt of the present invention, the swing motor drives the swing plate to rotate, thereby driving the sliding column to slide on the swing plate, and the sliding column slides to drive the sleeve to slide left and right on the sliding rod, thereby driving the position of the two connecting plates to swing, so that the swing shaft swings on the two support plates. In the process of spraying asphalt, the swing shaft will drive the position of the spray nozzle to swing left and right, and the swing shaft drives the spray nozzle to swing left and right, which can make the asphalt more evenly distributed in the width direction of the road; when the spray nozzle swings left and right, the asphalt can cover a wider area and contact the gravel at a more appropriate angle and thickness, just like providing a uniform and complete layer of glue (asphalt) to the puzzle pieces (gravel), so that the gravel can be more easily embedded in the asphalt to form a tight embedded structure. This good bonding effect can enhance the shear strength and stability of the seal layer, reduce the risk of gravel falling off during subsequent use, and thus extend the service life of the highway asphalt gravel synchronous seal layer; during the swinging process of the spray nozzle, the asphalt can be sprayed onto the base surface at different angles and positions, which helps to enhance the adhesion between the asphalt and the base layer, and improve the anti-skid performance and durability of the seal layer.

[0018] Secondly, the present invention's movable motor drives the movable gear to rotate. This rotation of the movable gear drives the two movable tooth plates at the bottom of the mounting frame to move closer to or farther from each other. The movement of the two movable tooth plates causes the positions of the spray nozzles to move back and forth horizontally. During the asphalt spraying process, first, the spraying distance can be adjusted according to the width of the road surface. By controlling the movement distance of the two movable tooth plates on the mounting frame, the asphalt can be sprayed comprehensively according to the road surface width. Second, the back-and-forth movement can achieve a more even distribution of asphalt within the spraying area. The reciprocating motion of the movable tooth plates causes the position of the spray nozzles to continuously change, just like moving a spray nozzle regularly on a plane. This ensures a more uniform asphalt spray thickness across both the width and length of the road. This is very important for ensuring the quality of the road asphalt layer and effectively prevents early damage to the road surface caused by uneven asphalt thickness, such as potholes and cracks.

DETAILED DESCRIPTION

[0030] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] The following describes in detail a technical solution of a highway asphalt macadam synchronous sealing robot according to various embodiments of the present invention in conjunction with the accompanying drawings.

[0032] Reference Figures 1 to 8 As shown, an embodiment of the present invention provides a highway asphalt gravel synchronous sealing robot, including a robot body 1, an asphalt placement bin 11 and a gravel placement bin 12 are provided at the rear of the robot body 1, and a mounting frame 13 is further provided at the rear of the robot body 1. A gravel distribution mechanism 2 for discharging gravel is provided in the mounting frame 13, and the gravel distribution mechanism 2 is rotatably connected to a position below the mounting frame 13. A spraying movement mechanism 3 and a spraying swing mechanism 4 are also provided on the mounting frame 13. The spraying movement mechanism 3 is arranged in the mounting frame 13 and the spraying movement mechanism 3 and the mounting frame 13 are slidably matched. The spraying swing mechanism 4 is located on the spraying movement mechanism 3, and a spraying member 5 connected to the asphalt placement bin 11 is provided on the spraying swing mechanism 4. A protective cover 6 is provided on the top of the mounting frame 13.

[0033] Specifically, refer to Figure 3 and Figure 4As shown, a conveying auger 121 is horizontally arranged in the gravel placement bin 12, and a conveying motor 122 is provided on the side wall of the gravel placement bin 12, which is transmission-connected to the conveying auger 121. An inclined conveying channel 123 extending into the installation frame 13 is provided on the side wall of the gravel placement bin 12; the inclined conveying channel 123 is a structure that is smaller at the top and larger at the bottom, and the installation frame 13 is provided with a plurality of discharge frames 124 arranged at equal intervals, and the plurality of discharge frames 124 are connected to the inclined conveying channel 123;

[0034] During use, the gravel is located in the gravel placement bin 12, and then the conveying motor 122 works to drive the conveying auger 121 to rotate in the gravel placement bin 12, thereby discharging the gravel from the gravel placement bin 12 to the outside into the inclined conveying channel 123. The inclined conveying channel 123 evenly discharges the gravel into several discharge frames 124, thereby achieving uniform discharge of the gravel.

[0035] Specifically, refer to Figure 5 As shown, the gravel distribution mechanism 2 includes a drive motor 21, a drive shaft 22 and a number of distribution parts equidistantly arranged in the discharge frame 124, the drive shaft 22 passes through the plurality of discharge frames 124 and the drive shaft 22 is rotatably connected to the plurality of discharge frames 124, the drive motor 21 is located on the side wall of the mounting frame 13 and is transmission-connected to the drive shaft 22, and the distribution parts include four distribution plates 23 equidistantly arranged on the drive shaft 22.

[0036] When the gravel falls into the discharge frame 124, the drive motor 21 starts to drive the drive shaft 22 to rotate, thereby driving the distribution plates 23 to rotate in the discharge frames 124, so that the gravel can be more evenly distributed at the outlet of the discharge frame 124. Because the distribution plates 23 can send the gravel in different directions during the rotation process, it can avoid the gravel being concentrated in a certain area of ​​the discharge frame 124. For example, for the spreading of gravel in the width direction of the road, uniform feeding can ensure that every square meter of the road surface can be covered with the appropriate amount of gravel, making the quality of the sealing layer more stable. Without this uniform feeding method, there may be too much gravel on some parts of the road surface, increasing the roughness of the road surface and affecting driving comfort; and too little gravel on some parts of the road surface will reduce the waterproof and wear-resistant properties of the sealing layer;

[0037] The rotating distribution plate 23 precisely controls the rate of gravel delivery based on the asphalt spraying speed and flow rate. When the asphalt spraying speed is high, the drive shaft 22 can be rotated faster to allow more gravel to fall. Conversely, when the asphalt spraying speed slows down, the amount of gravel delivered can be adjusted accordingly. This synchronization helps form a complete, well-bonded seal structure. For example, if the gravel is delivered too slowly during construction, the asphalt may solidify first, resulting in a loose bond between the gravel and the asphalt. On the other hand, if the gravel is delivered too quickly, some of the gravel may not bond well with the asphalt. The drive shaft 22 and distribution plate 23 effectively prevent these situations.

[0038] During the gravel feeding process, segregation is prone to occur, whereby gravel of different particle sizes is separated into layers. The rotation of the distribution plate 23 continuously stirs and mixes the gravel. As the drive shaft 22 rotates the distribution plate 23, the agitation of the distribution plate 23 allows the gravel of various sizes to be better mixed. This is similar to mixing objects of different sizes in a mixing vessel, where mixing prevents stratification caused by natural accumulation. For asphalt gravel simultaneous seals, preventing gravel segregation ensures the consistency of the seal material's performance. Gravel of different particle sizes plays a specific role in the seal structure, and a uniform mix of gravel provides improved intercalation and load-bearing capacity.

[0039] Specifically, refer to Figure 7 As shown, the spraying moving mechanism 3 includes a moving motor 31, a moving gear 32 and two moving tooth plates 33. The moving motor 31 is located in the installation frame 13, and the moving gear 32 is connected to the main shaft of the moving motor 31. The two moving tooth plates 33 are symmetrically slidably connected at the bottom position of the installation frame 13, and the moving gear 32 is engaged with the two moving tooth plates 33.

[0040] The movement of the moving motor 31 drives the moving gear 32 to rotate. The rotation of the moving gear 32 drives the two moving tooth plates 33 at the bottom of the mounting frame 13 to move closer to or farther from each other. The movement of the two moving tooth plates 33 drives the position of the spray nozzles 54 to move back and forth horizontally. During the asphalt spraying process, first, the spraying distance can be adjusted according to the width of the road surface. The movement distance of the two moving tooth plates 33 on the mounting frame 13 is controlled, so that the asphalt can be sprayed comprehensively according to the width of the road surface. Second, the back-and-forth movement process can achieve a more uniform distribution of asphalt within the spraying area. The reciprocating motion of the moving tooth plates 33 causes the position of the spray nozzles to change continuously, just like holding a spray nozzle and moving it regularly on a plane. This ensures a more uniform asphalt spray thickness across both the width and length of the road. This is very important for ensuring the quality of the road asphalt layer and can effectively prevent early damage to the road surface caused by uneven asphalt thickness, such as potholes and cracks.

[0041] Specifically, refer to Figure 8 As shown, the spraying swing mechanism 4 is constructed with two, and the two spraying swing mechanisms 4 are respectively arranged at the bottom position of the two moving tooth plates 33; each of the spraying swing mechanisms 4 includes a mounting frame 40, a swing motor 41, a swing plate 42, a swing shaft 43 and two support plates 44, and the two support plates 44 are symmetrically arranged at the two ends of the bottom of the moving tooth plate 33, and the two ends of the swing shaft 43 are respectively rotatably connected with the two support plates 44, and the mounting frame 40 is located in the middle position of the bottom of the moving tooth plate 33, and the swing plate 42 is connected to the main shaft of the swing motor 41, and the swing shaft 43 is provided with two symmetrically fixed connecting plates 45, and a sliding rod 46 is provided between the two connecting plates 45, and a sliding sleeve 47 is provided on the sliding rod 46, and a sliding column 48 is provided on the sleeve 47, and the sliding column 48 is slidably fitted with the swing plate 42.

[0042] During the process of spraying asphalt, the swing motor 41 drives the swing plate 42 to rotate, thereby driving the sliding column 48 to slide on the swing plate 42. The sliding of the sliding column 48 drives the sleeve 47 to slide left and right on the sliding rod, thereby driving the position of the two connecting plates 45 to swing, so that the swing shaft 43 swings on the two support plates 44. During the process of spraying asphalt, the swing shaft 43 will drive the position of the spray nozzle 54 to swing left and right. The swing shaft 43 drives the spray nozzle to swing left and right, which can make the asphalt more evenly distributed in the width direction of the road; when the spray nozzle swings left and right, the asphalt can cover a wider area and contact the gravel at a more appropriate angle and thickness, just like providing a uniform and complete layer of glue (asphalt) to the puzzle pieces (gravel), making it easier for the gravel to embed in the asphalt to form a tight embedded structure. This good bonding effect can enhance the shear strength and stability of the seal layer, reduce the risk of gravel falling off during subsequent use, and thus extend the service life of the highway asphalt gravel synchronous seal layer; when the spray nozzle swings, the asphalt can be sprayed onto the base surface at different angles and positions, which helps to enhance the adhesion between the asphalt and the base.

[0043] Specifically, there are two spraying parts 5, and each of the two spraying parts 5 includes a delivery pump 51, a delivery pipe 52, a connecting pipe 53, a plurality of spray nozzles 54 and a plurality of mounting seats 55. The plurality of mounting frames 13 are arranged at equal intervals at the bottom position of the swing shaft 43, and the plurality of spray nozzles 54 are respectively located on the plurality of mounting seats 55. The connecting pipe 53 is connected to the plurality of spray nozzles 54. The delivery pump 51 is located on the robot body 1 and is located next to the asphalt placement bin 11. One end of the delivery pipe 52 is connected to the asphalt placement bin 11 and to the delivery pump 51, and the other end of the delivery pipe 52 extends to be connected to the connecting pipe 53.

[0044] When spraying asphalt on the road surface, the delivery pump 51 extracts the asphalt in the asphalt storage bin 11 through the delivery pipe 52, and then delivers it to the connecting pipe 53. The connecting pipe 53 delivers the asphalt to several spray nozzles 54, and the several spray nozzles 54 will spray the asphalt evenly outward onto the road surface.

[0045] The foregoing is merely an embodiment of the present invention and is not intended to limit the present invention. It will be apparent to those skilled in the art that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are intended to be included within the scope of the claims of the present invention.
