Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular to an asphalt spraying device. Background Technology

[0002] Asphalt spraying equipment is a key piece of equipment in road construction, mainly used for asphalt spraying operations during asphalt pavement paving or maintenance. With the diversification of road construction needs, higher requirements are placed on the uniformity of spraying, anti-clogging ability and adaptability of the equipment. Traditional equipment has problems such as easy clogging of nozzles, insufficient spraying volume control accuracy and high heating energy consumption when facing asphalt containing impurities or complex road conditions. Moreover, the mechanical structure is mostly fixed, which makes it difficult to meet the construction needs of irregular road surfaces.

[0003] A search revealed Chinese Patent Publication No. CN222878449U, which discloses an asphalt spraying device. This device includes a support assembly, a storage tank, a moving assembly, a spraying assembly, and an marking assembly. The storage tank, located on the support assembly, stores asphalt emulsion. The moving assembly, also on the support assembly, moves the support assembly. The spraying assembly, connected to the storage tank, sprays the asphalt emulsion from the storage tank onto the road surface. The marking assembly, located on the support assembly, indicates the spraying range of the spraying assembly. This asphalt spraying device, by using the marking assembly to indicate the spraying range, allows operators to estimate the actual spraying position in advance, facilitating the initial selection of the spraying location. This reduces the reliance on manual experience and the technical requirements for operators in asphalt spraying operations. However, in actual use, spraying control often employs solenoid valves or mechanical valves, which have slow response times and can become stuck due to asphalt solidification, leading to uneven spraying. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an asphalt spraying device, which aims to improve the problem of slow response speed of electromagnetic valves or mechanical valves in the prior art, and valve jamming due to asphalt solidification.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an asphalt spraying device, including a mobile platform, a spraying mechanism on the right side of the mobile platform, a constant temperature mechanism on the top left side of the mobile platform, rotatably connected to the outer walls of the mobile platform, a lifting assembly on the top right side of the mobile platform, a push column fixedly connected to the left side of the mobile platform, and a suction assembly on the top front side of the mobile platform. The spraying mechanism includes a U-shaped plate, the left side of which is slidably connected to the right side of the mobile platform. Fixed cylinders are fixedly connected to the front and rear sides of the right side of the U-shaped plate. A triangular arc-shaped cylinder is rotatably connected to the inner wall of the fixed cylinder. A shaftless auger is fixedly connected to the inner wall of the triangular arc-shaped cylinder. Adjacent sides of the two shaftless augers penetrate the outer wall of the fixed cylinder and are fixedly connected to a linkage gear. Collection components are provided on opposite sides of the inner walls of the two fixed cylinders. A drive component is provided at the bottom of the U-shaped plate. Multiple spray nozzles are connected to the bottom end of the outer wall of the fixed cylinder.

[0006] The above technical solution works as follows: the rotating wheels allow the mobile platform to move as needed. By activating the drive assembly, the triangular arc-shaped cylinders on both sides rotate inside the fixed cylinder. When the arc-shaped baffle above the triangular arc-shaped cylinder blocks the bottom of the fixed cylinder, the asphalt cannot be sprayed from the nozzle. When the gap above the triangular arc-shaped cylinder rotates to the bottom of the fixed cylinder, the asphalt is sprayed out through the nozzle. The high-speed rotation of the triangular arc-shaped cylinder causes the arc-shaped baffle above it to continuously scrape, preventing impurities or particles in the asphalt from entering the nozzle. At the same time, the impurities or particles in the asphalt are pushed to both sides by the rotation of the shaftless auger, causing the impurities or particles to enter the collection assembly.

[0007] As a further description of the above technical solution: The constant temperature mechanism includes a constant temperature barrel, the bottom of which is fixedly connected to the top left side of the moving platform. A heating device is fixedly connected to the top center of the moving platform. A heat-conducting column is fixedly connected to the left side of the heating device. The left end of the heat-conducting column penetrates the outer wall of the constant temperature barrel and is fixedly connected to an anti-stick sleeve. Multiple heat dissipation rings are fixedly connected to the outer wall of the anti-stick sleeve. A sealing assembly is provided at the top of the constant temperature barrel. A control device is fixedly connected to the top of the heating device.

[0008] The above technical solution involves adding asphalt into a constant temperature tank through a semi-conical feed block. Once the tank is full, the heating equipment is activated. The heat-conducting column heats the anti-stick sleeve and the outer heat dissipation ring, thereby heating and maintaining the temperature of the asphalt in the constant temperature tank. This ensures that the asphalt remains in a liquid state and prevents it from cooling and solidifying in the equipment, which could lead to blockage.

[0009] As a further description of the above technical solution: The collecting assembly includes two cover caps, the outer walls of which are threaded to the inner walls of the corresponding U-shaped plates. A conical ring is fixedly connected to the inner wall of each cover cap, and the outer wall of the conical ring has multiple connecting holes.

[0010] The above technical solution involves rotating the cover cap to remove it, which facilitates the cleaning of impurities or particles. The conical ring prevents impurities or particles from flowing back into the fixed cylinder. Furthermore, the connecting hole above the cover cap allows asphalt to flow back into the fixed cylinder from the cover cap, thus preventing impurities or particles in the asphalt from clogging the spray nozzle during use.

[0011] As a further description of the above technical solution: The drive assembly includes a DC motor, the top of which is fixedly connected to the middle of the bottom of the U-shaped plate, and a drive gear is fixedly connected to the output end of the DC motor.

[0012] The above technical solution involves starting the DC motor in the drive assembly, causing the drive gear to rotate, which in turn drives the linkage gear to rotate.

[0013] As a further description of the above technical solution: The sealing assembly includes a semi-conical feed block whose bottom end is connected to the top of the constant temperature barrel. A semi-circular block is rotatably connected to the inner wall of the semi-conical feed block. A limiting rod is fixedly connected to the top of the semi-circular block. A T-shaped locking block is slidably connected to the middle of the top of the semi-conical feed block. The outer wall of the semi-circular block engages with the inner wall of the semi-conical feed block.

[0014] The above technical solution involves rotating the semicircular block to close the semi-conical feed block, and then sliding the T-shaped locking block to engage the limiting rod with the T-shaped locking block, thereby completing the fixation.

[0015] As a further description of the above technical solution: The lifting assembly includes a placement groove. The outer wall of the placement groove is formed on the top right side of the mobile platform. A hydraulic rod is fixedly connected to the left side of the inner wall of the placement groove. One end of the hydraulic rod is scraped and connected to a U-shaped block. Sliding grooves are formed on both the front and rear sides of the inner wall of the placement groove. The front and rear sides of the outer wall of the U-shaped block are slidably connected to the inner walls of the corresponding sliding grooves. A rotating plate is rotatably connected to the inner wall of the U-shaped block. The right end of the rotating plate is rotatably connected to the bottom center of the U-shaped plate.

[0016] The above technical solution involves placing a groove to provide installation space for the hydraulic rod, then starting the hydraulic rod, which in turn moves the U-shaped block. Simultaneously, the rotating plate rotates as the U-shaped block moves, causing the U-shaped plate to move up and down above the moving platform, thereby changing the position of the entire spray nozzle. The sliding groove restricts the direction of movement of the U-shaped block.

[0017] As a further description of the above technical solution: The suction assembly includes a suction pump. The bottom of the suction pump is fixedly connected to the top front side of the mobile platform. A suction pipe is connected to the left side of the suction pump. The other end of the suction pipe is connected to the front side of the constant temperature tank. A heat-insulating hose is connected to the other end of the suction pump. A U-shaped tube is connected to the other end of the heat-insulating hose. The front and rear ends of the U-shaped tube are respectively connected to the top of the outer wall of the corresponding fixed cylinder.

[0018] The above technical solution involves starting the suction pump to extract the asphalt to be sprayed, guiding the asphalt into the U-shaped pipe through the insulated hose, and then diverting it into the fixed cylinders on both sides.

[0019] As a further description of the above technical solution: The outer wall of the drive gear meshes with the outer wall of the linkage gear, and the inner wall dimension of the fixed cylinder is the same as the outer wall dimension of the triangular arc cylinder.

[0020] Through the above technical solution: the outer wall of the drive gear meshes with the outer wall of the linkage gear to realize the transmission of kinetic energy, while the inner wall size of the fixed cylinder is the same as the outer wall size of the triangular arc cylinder, ensuring that the triangular arc cylinder scrapes the inner wall of the fixed cylinder when rotating, avoiding impurities from clogging the spray nozzle.

[0021] This utility model has the following beneficial effects: 1. In this utility model, the rotation of the linkage gear causes the triangular arc-shaped cylinder to rotate simultaneously within the fixed cylinder 202. When the arc-shaped baffle of the triangular arc-shaped cylinder blocks the bottom of the fixed cylinder, the asphalt cannot be sprayed out. When the gap rotates to the bottom, the asphalt is sprayed out and scrapes the fixed cylinder under the high-speed rotating triangular arc-shaped cylinder, preventing impurities from entering the spray nozzle. The impurities are pushed to the collection component by the shaftless auger, thereby avoiding clogging the nozzle and causing uneven spraying.

[0022] 2. In this utility model, asphalt is fed into the constant temperature barrel through a semi-conical feeding block. The semi-circular block is rotated to close the feeding block. Then, the T-shaped locking block is slid to engage the limiting rod with the T-shaped locking block, thus sealing the constant temperature barrel. The heating equipment is then started, and the heat-conducting column heats the anti-stick sleeve and heat dissipation ring to ensure that the asphalt inside the barrel is heated and kept warm, preventing it from cooling and solidifying.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 5 , Figure 6 and Figure 8This utility model provides an embodiment of an asphalt spraying device, including a mobile platform 1, a spraying mechanism 2 on the right side of the mobile platform 1, a constant temperature mechanism 3 on the top left side of the mobile platform 1, and rotatable wheels 4 rotatably connected to the outer walls of the mobile platform 1. The rotation of the wheels 4 allows the mobile platform 1 to move as needed. A lifting assembly 5 is located on the top right side of the mobile platform 1, a push column 6 is fixedly connected to the left side of the mobile platform 1, and a suction assembly 8 is located on the top front side of the mobile platform 1. Under the action of the suction assembly 8, the asphalt to be sprayed is diverted into a fixed cylinder 202; the spraying mechanism 2... The system includes a U-shaped plate 201, with its left side slidably connected to the right side of the mobile platform 1. Fixed cylinders 202 are fixedly connected to the front and rear sides of the right side of the U-shaped plate 201. A triangular arc-shaped cylinder 203 is rotatably connected to the inner wall of the fixed cylinder 202. When the arc-shaped baffle above the triangular arc-shaped cylinder 203 blocks the bottom of the fixed cylinder 202, asphalt cannot be sprayed from the nozzle 208. When the gap above the triangular arc-shaped cylinder 203 rotates to the bottom of the fixed cylinder 202, asphalt is sprayed through the nozzle 208. A shaftless auger 2 is fixedly connected to the inner wall of the triangular arc-shaped cylinder 203. 04. Impurities or particulate matter in the green are pushed to both sides by the rotation of the shaftless auger 204. The adjacent sides of the two shaftless augers 204 pass through the outer wall of the fixed cylinder 202 and are fixedly connected to the linkage gear 205. Under the rotation of the linkage gear 205, the triangular arc-shaped cylinders 203 on both sides rotate inside the fixed cylinder 202. The inner walls of the two fixed cylinders 202 are provided with collection components 206 on the side away from each other. The bottom of the U-shaped plate 201 is provided with a drive component 207. The bottom end of the outer wall of the fixed cylinder 202 is connected to multiple spray nozzles 208. The collection component 206 includes two cover caps 20. 61. The outer walls of the two cover caps 2061 are respectively threaded to the inner walls of the corresponding U-shaped plates 201. A conical ring 2062 is fixedly connected to the inner wall of the cover cap 2061. The outer wall of the conical ring 2062 has multiple connecting holes 2063. The drive assembly 207 includes a DC motor 2071. The top of the DC motor 2071 is fixedly connected to the middle of the bottom end of the U-shaped plate 201. The output end of the DC motor 2071 is fixedly connected to a drive gear 2072. When the DC motor 2071 in the drive assembly 207 is started, the drive gear 2072 rotates, thereby driving the linkage gear 205 to rotate. Specifically, the rotation of the moving wheel 4 causes the moving platform 1 to move as needed. Under the action of the suction component 8, the asphalt to be sprayed is diverted into the fixed cylinder 202. By starting the DC motor 2071 in the drive component 207, the drive gear 2072 rotates. Then, under the rotation of the linkage gear 205, the triangular arc-shaped cylinders 203 on both sides rotate inside the fixed cylinder 202. When the arc-shaped baffle above the triangular arc-shaped cylinder 203 blocks the bottom of the fixed cylinder 202, the asphalt cannot be sprayed out from the spray nozzle 208. When the gap above the triangular arc-shaped cylinder 203 rotates to the bottom of the fixed cylinder 202, the asphalt is sprayed out through the spray nozzle 208 and passes through the triangular arc-shaped cylinder 203 at high speed. As the cylinder rotates, the arc-shaped baffle above the triangular arc-shaped cylinder 203 continuously scrapes, preventing impurities or particles in the asphalt from entering the spray nozzle 208. Simultaneously, the impurities or particles in the asphalt are pushed to both sides by the rotation of the shaftless auger 204, causing them to enter the collection component 206. When the asphalt spraying is complete, simply rotate the cover cap 2061 to remove it, making it easier to clean the impurities or particles. The conical ring 2062 prevents impurities or particles from flowing back into the fixed cylinder 202, and the connecting hole 2063 above it allows the asphalt to flow back into the fixed cylinder 202 from the cover cap 2061 through the connecting hole 2063, thus preventing impurities or particles in the asphalt from clogging the spray nozzle 208 during use.

[0027] Reference Figure 1 , Figure 3 and Figure 7The temperature control mechanism 3 includes a temperature control tank 301. The bottom end of the temperature control tank 301 is fixedly connected to the top left side of the moving platform 1. A heating device 302 is fixedly connected to the top center of the moving platform 1. A heat-conducting column 303 is fixedly connected to the left side of the heating device 302. The left end of the heat-conducting column 303 penetrates the outer wall of the temperature control tank 301 and is fixedly connected to an anti-stick sleeve 305. Multiple heat dissipation rings 304 are fixedly connected to the outer wall of the anti-stick sleeve 305. When the heating device 302 is activated, the heat-conducting column 303 heats the anti-stick sleeve 305 and the outer heat dissipation rings 304, thereby heating and keeping the asphalt placed in the temperature control tank 301 warm. A sealing component 306 is provided at the top of the temperature control tank 301. The heating device 302 is fixedly connected to the top of the regulating device 7; the sealing assembly 306 includes a semi-conical feeding block 3061 whose bottom end is connected to the top of the constant temperature barrel 301, a semi-circular block 3062 rotatably connected to the inner wall of the semi-conical feeding block 3061, a limiting rod 3063 fixedly connected to the top of the semi-circular block 3062, and a T-shaped locking block 3064 slidably connected to the middle of the top of the semi-conical feeding block 3061. The outer wall of the semi-circular block 3062 engages with the inner wall of the semi-conical feeding block 3061. Rotating the semi-circular block 3062 closes the semi-conical feeding block 3061. Then, sliding the T-shaped locking block 3064 causes the limiting rod 3063 to engage with the T-shaped locking block 3064, thereby completing the fixing. Specifically, asphalt is added to the constant temperature tank 301 through the semi-conical feed block 3061. After the asphalt is filled, the semi-circular block 3062 is rotated to close the semi-conical feed block 3061. Then, the T-shaped locking block 3064 is slid to engage the limiting rod 3063 with the T-shaped locking block 3064, thereby completing the fixation and closing the constant temperature tank 301. At this time, the heating device 302 is started, and the heat conduction column 303 heats the anti-stick sleeve 305 and the outer heat dissipation ring 304, thereby heating and keeping the asphalt placed in the constant temperature tank 301 warm, ensuring that the asphalt is always in a liquid state and preventing it from cooling and solidifying in the equipment, thus causing blockage.

[0028] Reference Figure 1 , Figure 2 and Figure 4The lifting assembly 5 includes a placement groove 501. The outer wall of the placement groove 501 is formed on the top right side of the moving platform 1. The placement groove 501 provides installation space for the hydraulic rod 502. The hydraulic rod 502 is fixedly connected to the left side of the inner wall of the placement groove 501. One end of the hydraulic rod 502 is scraped and connected to a U-shaped block 503. Sliding grooves 504 are formed on both the front and rear sides of the inner wall of the placement groove 501. The front and rear sides of the outer wall of the U-shaped block 503 are slidably connected to the inner walls of the corresponding sliding grooves 504. A rotating plate 505 is rotatably connected to the inner wall of the U-shaped block 503. The right end of the rotating plate 505 is rotatably connected to the middle of the bottom end of the U-shaped plate 201. When the hydraulic rod 502 is activated, it drives the U-shaped block 503 to move. At the same time, the rotating plate 505 rotates as the U-shaped block 503 moves, thereby causing the U-shaped plate 201 to move up and down above the moving platform 1. The suction assembly 8 includes a suction pump 801, the bottom of which is fixedly connected to the top front side of the mobile platform 1. A suction pipe 802 is connected to the left side of the suction pump 801, and the other end of the suction pipe 802 is connected to the front side of the constant temperature tank 301. The other end of the suction pump 801 is connected to a heat-insulating hose 803, and the other end of the heat-insulating hose 803 is connected to a U-shaped pipe 804. The front and rear ends of the U-shaped pipe 804 are respectively connected to the top of the outer wall of the corresponding fixed cylinder 202. Under the action of the suction pump 801 in the suction assembly 8, the asphalt to be sprayed is extracted and guided into the U-shaped pipe 804 through the heat-insulating hose 803, and then diverted into the fixed cylinders 202 on both sides. The outer wall of the drive gear 2072 is meshed with the outer wall of the linkage gear 205. The inner wall size of the fixed cylinder 202 is the same as the outer wall size of the triangular arc cylinder 203. Specifically, the groove 501 provides installation space for the hydraulic rod 502. The hydraulic rod 502 is then activated, causing the U-shaped block 503 to move. Simultaneously, the rotating plate 505 rotates as the U-shaped block 503 moves, causing the U-shaped plate 201 to move up and down above the moving platform 1, thus changing the position of the entire spray nozzle 208. The sliding groove 504 restricts the direction of movement of the U-shaped block 503. Under the action of the suction pump 801 in the suction assembly 8, the required asphalt is extracted and guided through the insulated hose 803 into the U-shaped tube 804, and then diverted into the fixed cylinders 202 on both sides. The asphalt enters the constant temperature tank 301 through the semi-conical feed block 3061. Rotating the semi-circular block 3062 closes the semi-conical feed block 3061. Then, sliding the T-shaped locking block 3064 engages the limiting rod 3063 with the T-shaped locking block 3064, sealing the constant temperature tank 301.

[0029] Working principle: First, with the rotation of the moving wheels 4, the moving platform 1 can move accordingly as needed. The suction pump 801 in the suction assembly 8 extracts the asphalt to be sprayed and guides it to the U-shaped pipe 804 through the heat-insulating hose 803. Then, it is diverted to the fixed cylinders 202 on both sides. By starting the DC motor 2071 in the drive assembly 207, the drive gear 2072 starts to rotate, which in turn drives the linkage gear 205, causing the triangular arc-shaped cylinders 203 on both sides to rotate inside the fixed cylinder 202. When the arc-shaped baffle above the triangular arc-shaped cylinder 203 blocks the bottom of the fixed cylinder 202, the asphalt cannot be sprayed from the spray nozzle 208; and when the gap above the triangular arc-shaped cylinder 203 rotates to the fixed cylinder 202, the asphalt cannot be sprayed from the nozzle 208. At the bottom of 2, asphalt is sprayed out through the spray nozzle 208. The high-speed rotation of the triangular arc-shaped cylinder 203 causes the arc-shaped baffle to scrape continuously, effectively preventing impurities or particles in the asphalt from entering the spray nozzle 208. At the same time, these impurities or particles are guided to the collection component 206 by the shaftless auger 204. After the asphalt spraying is completed, it is only necessary to rotate and remove the cover cap 2061 to facilitate the cleaning of impurities or particles. The interception effect of the conical ring 2062 prevents impurities or particles from flowing back to the fixed cylinder 202, while the connecting hole 2063 above it allows asphalt to flow back to the fixed cylinder 202 from the cover cap 2061 through the connecting hole 2063, thereby avoiding the clogging of the spray nozzle 208 by impurities or particles in the asphalt during use. Furthermore, through the constant temperature mechanism 3, asphalt is injected into the constant temperature tank 301 through the semi-conical feed block 3061. After the asphalt is filled, the semi-circular block 3062 is rotated to close the semi-conical feed block 3061. Then, the T-shaped locking block 3064 is slid to make the limiting rod 3063 engage with the T-shaped locking block 3064, thereby achieving fixation. In this way, the constant temperature tank 301 is completely closed. Subsequently, the heating device 302 is started, and the heat-conducting column 303 is used to heat the anti-stick sleeve 305 and the outer heat dissipation ring 304 to heat and keep the asphalt in the constant temperature tank 301 warm, ensuring that the asphalt remains liquid and preventing it from solidifying inside the equipment due to cooling, thereby avoiding blockage.
