Description

Technical Field

[0001] The utility model relates to the technical field of pavement crack filling, in particular to an automatic pavement crack filling machine. Background Art

[0002] As the road surface is used for a longer time, cracks and irregular potholes will appear on the asphalt road surface. In order to ensure the normal use of the asphalt road surface, the cracks need to be repaired. Among them, the automatic pavement crack filling machine is a more common equipment for crack repair.

[0003] After searching, the Chinese patent "A Asphalt Pavement Sealing Machine for Highway Maintenance" authorization announcement number is "CN220364840U". In this device, workers do not need to hold the spray gun for a long time to spray the cracks, which reduces the labor intensity of workers. The electric-controlled hydraulic rod 202 pushes the flattening roller to contact the ground, and at the same time uses the complex hydraulic rod 204 to drive the flattening roller 206 to flatten the ground back and forth, solving the problem that if the flattening process is not carried out in time, the road surface will still be uneven after the asphalt solidifies, or the gaps on both sides are not filled solidly.

[0004] Although the flattening roller used in the above application can flatten the filled asphalt, asphalt will adhere to the surface of the flattening roller during the flattening process, resulting in an uneven surface of the flattening roller, thereby affecting the flattening effect of the flattening roller on the filled cracks.

[0005] Therefore, an automatic pavement crack filling machine is proposed to solve the above problems. Utility Model Content

Due to the diameter difference between the first and second pulleys, the rotational speed of the reciprocating screw driven by the first pulley is advantageously greater than the rotational speed of the flattening roller, thereby ensuring the cleaning effect of the cleaning plate on the scraper.

[0010] Preferably, baffles are fixedly connected to both sides of the top of the collection frame, the baffles are arranged at an angle, and one side of the baffles contacts the surface of the flattening roller, which is conducive to allowing the cleaned asphalt to enter the collection frame for collection better.

[0012] Preferably, the vertical cross section of the scraper is a right triangle, and the bottom end of the cleaning plate is in oblique contact with the scraper, which is conducive to better scraping the asphalt on the surface of the flattening roller.

[0013] Preferably, both sides of the cleaning plate form an angle with the vertical plane, which is beneficial for the cleaning plate to guide the impurities cleaned on the scraper, so that the cleaned impurities can enter the collection frame better.

[0014] Preferably, a limit rod is fixedly connected to the surface of the mounting plate, and the other end of the limit rod passes through the moving vehicle, which is beneficial for limiting the movement of the mounting plate and the mounting frame and enhancing the stability of the device during operation.

Moreover, during the rotation of the flattening roller, the scraper is used to scrape off the asphalt adhering to the surface of the flattening roller, and the cleaned asphalt is collected by the collecting frame, which is beneficial to keeping the surface of the flattening roller in a flat state at all times to flatten the filled asphalt, thereby improving the flattening effect of the flattening roller on the asphalt. At the same time, during the rotation of the flattening roller, the reciprocating screw is driven to drive the cleaning plate to move back and forth through the connecting rod to clean the asphalt on the inclined surface of the scraper, which is beneficial to keeping the scraper clean and cleaning the surface of the flattening roller, thereby enhancing the cleaning effect of the scraper on the surface of the flattening roller;

[0017] Under the effect of the diameter difference between the first pulley and the second pulley, the rotation speed of the reciprocating screw driven by the first pulley is greater than the rotation speed of the flattening roller, thereby ensuring the cleaning effect of the cleaning plate on the scraper.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the 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.

[0024] When implementing: Figure 1-4As shown, an automatic road crack filling machine includes: a mobile vehicle 1, a crack filling machine 2 is installed on the top of the mobile vehicle 1, a fan 3 is installed on one side of the top of the mobile vehicle 1, the air outlet of the fan 3 is connected to the blowing pipe 4, and a flattening mechanism 5 is provided on one side of the mobile vehicle 1;

[0025] Among them, the flattening mechanism 5 includes an electric push rod 51 fixedly connected to one side of the mobile vehicle 1, the bottom end of the electric push rod 51 is fixedly connected to the mounting plate 52, one end of the mounting plate 52 is fixedly connected to the mounting frame 53, the inner wall of the mounting frame 53 is rotatably connected to the flattening roller 54, one side of the mounting frame 53 is fixedly connected to the collecting frame 55, the top of the collecting frame 55 is fixedly connected to the scraper 56, one side of the scraper 56 is in contact with the surface of the flattening roller 54, the inner wall of the mounting frame 53 is rotatably connected to the reciprocating screw 57, the surface of the reciprocating screw 57 is provided with a connecting rod 58, the other end of the connecting rod 58 passes through the mounting frame 53 and is fixedly connected to the cleaning plate 59.

[0026] The crack filling machine 2 is a relatively common device in the prior art. When filling cracks in the road surface, the mobile vehicle 1 is used to move the crack filling machine 2 to the desired position, and the discharge pipe in the crack filling machine 2 is aligned with the crack. The controller starts the fan 3 to blow air out of the blowing pipe 4. This method is the same as the original solution. The blowing pipe 4 can be extended and retracted, and the controller starts the electric push rod 51 to push the surface of the flattening roller 54 to contact the ground, pushing the mobile vehicle 1 forward. At this time, the blowing pipe 4 will clean the crack. After cleaning, the discharge pipe of the crack filling machine 2 fills the crack with asphalt. After filling, the flattening mechanism 5 flattens the crack. The midpoint of the flattening roller 54 is located on the same horizontal plane as the midpoint of the discharge pipe of the crack filling machine 2 and the midpoint of the blowing pipe 4.

[0027] like Figure 2 and Figure 4 As shown, the flattening mechanism 5 also includes a second pulley 511 fixedly connected to one end of the rotating shaft of the flattening roller 54, one end of the reciprocating screw 57 passes through the mounting frame 53 and is fixedly connected to the first pulley 510, and a transmission belt 512 is connected between the first pulley 510 and the second pulley 511.

[0028] When the surface of the flattening roller 54 contacts the ground, when the mobile vehicle 1 is pushed to move, the flattening roller 54 will rotate while moving under the action of the friction between the flattening roller 54 and the ground, thereby driving the second pulley 511 to rotate, and driving the first pulley 510 to rotate synchronously under the action of the transmission belt 512. The diameter of the first pulley 510 is smaller than the diameter of the second pulley 511. Therefore, the rotation speed of the first pulley 510 is greater than the rotation speed of the second pulley 511. A protective frame is installed on the surface of the mounting frame 53, and the first pulley 510, the second pulley 511 and the transmission belt 512 are arranged in the protective frame.

[0029] like Figure 4 As shown, baffles 514 are fixedly connected to both sides of the top of the collection frame 55. The baffles 514 are arranged at an angle, and one side of the baffles 514 contacts the surface of the flattening roller 54. The two baffles 514 form a trumpet-shaped opening on one side of the top of the collection frame 55. The bottom end of the collection frame 55 forms an angle with the horizontal plane, and when the flattening roller 54 contacts the ground, the bottom end of the collection frame 55 is away from the ground.

[0030] like Figure 3 As shown, a plurality of annularly distributed grooves 515 are provided at both ends of the surface of the flattening roller 54. When the mobile vehicle 1 pushes the flattening roller 54 to move, the grooves 515 increase the friction between the flattening roller 54 and the ground.

[0031] like Figure 3 As shown, the vertical cross-section of the scraper 56 is a right triangle, and the bottom end of the cleaning plate 59 is in oblique contact with the scraper 56.

[0032] During the rotation of the flattening roller 54 , the scraper 56 cleans the asphalt on the surface of the flattening roller 54 , and the cleaned asphalt enters the collection frame 55 through the inclined surface of the scraper 56 .

[0033] like Figure 4 As shown, both sides of the cleaning plate 59 form an angle with the vertical plane, which is conducive to guiding the asphalt being cleaned.

[0034] like Figure 2 As shown, the surface of the mounting plate 52 is fixedly connected to a limit rod 513, and the other end of the limit rod 513 extends through the mobile vehicle 1. The surface of the limit rod 513 is slidably connected to the inner wall of the mobile vehicle 1. When the electric push rod 51 drives the mounting plate 52 to move up and down, it also drives the limit rod 513 to move up and down synchronously.

[0035] When the utility model is in use, the mobile vehicle 1 is used to move the crack filling machine 2 to the required position, so that the discharge pipe in the crack filling machine 2 is aligned with the crack, and the electric push rod 51 is started by the controller to push the mounting plate 52 to drive the mounting frame 53 and the flattening roller 54 to move downward, so that the surface of the flattening roller 54 is in contact with the ground. After completing this operation, the mobile vehicle 1 is pushed forward, and the fan 3 is started by the controller to blow air out of the crack from the blowing pipe 4 for cleaning. At the same time, the crack filling machine 2 is driven to run so that the discharge pipe of the crack filling machine 2 fills the crack with asphalt. During the movement of the mobile vehicle 1, the flattening roller 54 is rotated under the action of the friction between the flattening roller 54 and the ground to flatten the filled asphalt. Flattening, and during the rotation of the flattening roller 54, when the asphalt adhered to the surface of the flattening roller 54 passes through the scraper 56, the scraper 56 will scrape the asphalt, and the scraped asphalt will enter the collecting frame 55. When the flattening roller 54 rotates, it will drive the second pulley 511 to rotate, and under the action of the transmission belt 512, it will drive the reciprocating screw 57 to rotate synchronously through the first pulley 510, thereby driving the connecting rod 58 to move back and forth. When the connecting rod 58 moves back and forth, it will drive the cleaning plate 59 to move synchronously, so that the cleaning plate 59 cleans the asphalt on the surface of the scraper 56, so that the scraper 56 remains clean and cleans the surface of the flattening roller 54.

[0036] The reciprocating screw 57 is in the form of two thread grooves with the same pitch and opposite rotation direction, and the two ends are connected by a transition curve. Through the rotation of the reciprocating screw 57, the side of the spiral groove pushes the slider placed in the spiral groove to perform axial reciprocating motion. Therefore, when the reciprocating screw 57 rotates, it will drive the connecting rod 58 to move back and forth.

[0037] It should be noted that the electric push rods 51 and the like in the above description are all relatively mature devices in existing technology applications. The specific models can be selected according to actual needs. At the same time, the electric push rods 51 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0038] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
