Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0023] See also Figure 1-4A device for filling asphalt for road cracks includes a base plate 1, a storage tank 2 and a push rod 5 are fixedly connected to the upper side of the base plate 1, a flow pipe 31 is fixedly connected to the interior of the storage tank 2, and one end of the flow pipe 31 passes through the base plate 1, the upper end of the flow pipe 31 is connected to the interior of the storage tank 2, and a valve body 32 is arranged on the outer side of the flow pipe 31. The base plate 1 can play a role in installing and fixing the storage tank 2, and the storage tank 2 can be used to store asphalt particles that need to fill the cracks. At the same time, the setting of the flow pipe 31 allows the asphalt particles stored in the storage tank 2 to flow smoothly through the flow pipe 31 to the ground, thereby filling the cracks in the road, and the valve body 32 can play a role in opening and closing control of the flow pipe 31, so that when the cracks do not need to be filled, the asphalt is not easy to flow to the ground through the flow pipe 31 at will.

[0024] Specifically, a rotating pressure roller 6 and a connecting block 41 are provided on the lower side of the base plate 1, and a universal wheel 42 is fixedly connected to the lower side of the connecting block 41. The base plate 1 can be connected to the universal wheel 42 through the connecting block 41, and the setting of the universal wheel 42 enables the staff to push the base plate 1 smoothly and simply, and the push rod 5 can facilitate people to move the base plate 1 through the universal wheel 42, and make it easy to push the base plate 1. The rotating pressure roller 6 can flatten the asphalt particles that flow to the ground through the circulation pipe 31, and an adjustment mechanism is provided on the lower side of the base plate 1. The setting of the adjustment mechanism enables the staff to smoothly and simply adjust the outlet size of the lower end of the circulation pipe 31 when encountering narrow or uneven cracks, and when encountering narrow cracks, the asphalt particles flowing out through the circulation pipe 31 are not easy to flow out too much.

[0025] Specifically, the adjustment mechanism includes a fixed rod 76 fixedly connected to the lower side of the circulation tube 31, and the outer side of the fixed rod 76 is rotatably connected to a blocking block 71. The circulation tube 31 can be connected to the blocking block 71 through the fixed rod 76, and the blocking block 71 can block the outlet on the lower side of the circulation tube 31 through the rotational connection between itself and the fixed rod 76, thereby achieving the effect of changing the size of the outlet of the circulation tube 31, and the outer side of the blocking block 71 is rotatably connected to the connecting telescopic rod 72, and the blocking block 71 can also play a role in installing and connecting the connecting telescopic rod 72, so that the connecting telescopic rod 72 can be used smoothly. The lower side of the base plate 1 is fixedly connected to a connecting plate 75, and one side of the connecting plate 75 is rotatably connected to a screw rod 74, and the outer side of the screw rod 74 is threadedly connected to a threaded block 73. The base plate 1 can install the screw rod 74 through the connecting plate 75, and the screw rod 74 can be rotated smoothly.

[0026] Specifically, the screw rod 74 can be connected to the threaded block 73, and the threaded block 73 is rotatably connected to the connecting telescopic rod 72, so that when the screw rod 74 rotates, the blocking block 71 can smoothly limit the threaded block 73 through the connecting telescopic rod 72, so that the threaded block 73 can be smoothly moved by the rotation of the screw rod 74, and the threaded block 73 will drive the connecting telescopic rod 72 to move through the connection relationship between itself and the connecting telescopic rod 72 when moving. The connecting telescopic rod 72 itself is not easy to be extended and moved when moving, and while moving, it can also pull the blocking block 71 to make the blocking block 71 rotates around the fixed rod 76 to adjust the position of the blocking block 71, and by adjusting the position of the blocking block 71, the size of the outlet at the lower end of the circulation tube 31 is adjusted, so that when the circulation tube 31 comes into contact with a narrow crack, it is not easy for too many asphalt particles to flow out. The connecting telescopic rod 72 is composed of a first telescopic rod and a second telescopic rod, and the first telescopic rod is movably inserted into the inside of the second telescopic rod, so that the connecting telescopic rod 72 can smoothly follow the movement of the screw rod 74 to extend and retract when the screw rod 74 moves, and reduces the possibility of obstructing the rotation of the blocking block 71 due to the inability of the connecting telescopic rod 72 to extend and retract smoothly.

[0027] Specifically, a mounting plate 81 is fixedly connected to one side of the connecting plate 75, and a first servo motor 82 is fixedly connected to the upper side of the mounting plate 81. The output shaft of the first servo motor 82 passes through the connecting plate 75, and the output shaft of the first servo motor 82 is fixedly connected to the screw 74 through a coupling. The connecting plate 75 can install and fix the first servo motor 82 through the mounting plate 81, and the first servo motor 82 can drive the screw 74 to rotate during operation, so that when the staff needs to rotate the screw 74, it can be simple and convenient enough.

[0028] Specifically, a cover plate 103 is provided on the upper side of the storage tank 2, and the cover plate 103 can play a certain closing role on the upper side of the storage tank 2, thereby reducing the possibility of dust and debris falling into the storage tank 2. A second servo motor 101 is fixedly connected to the upper side of the cover plate 103, and the output shaft of the second servo motor 101 passes through the cover plate 103. The output shaft of the second servo motor 101 is fixedly connected to a stirring block 102 through a coupling, and the stirring block 102 is rotatably connected to the inner side of the storage tank 2. The cover plate 103 can install and fix the stirring block 102 through the second servo motor 101, and the second servo motor 101 can drive the stirring block 102 to rotate through its own operation, so that the stirring block 102 can smoothly stir the asphalt inside the storage tank 2 through its own rotation, thereby reducing the possibility of asphalt particles solidifying inside the storage tank 2.

[0029] Specifically, a hollow groove 111 is opened on the inner side of the storage tank 2, and a heating plate 112 is fixedly connected to the storage tank 2 inside the hollow groove 111. The storage tank 2 can install and fix the heating plate 112 through the hollow groove 111, and the heating plate 112 can heat the inside of the storage tank 2 during operation, thereby cooperating with the stirring block 102 to further reduce the possibility of solidification of asphalt particles inside the storage tank 2 and increase the fluidity of the asphalt particles. At the same time, the heating plate 112 is similar to the principle of the existing electric heating resistance wire, so the specific working process of the heating plate 112 will not be elaborated here.

[0030] The working principle and use process of the utility model: when the device is in use, the staff can add the asphalt particles needed to be used into the interior of the storage tank 2, and after adding, install the cover plate 103 to the upper side of the storage tank 2, and start the second servo motor 101 and the heating plate 112 at the same time. At this time, the second servo motor 101 will drive the stirring block 102 to rotate, and the heating plate 112 can heat the interior of the storage tank 2, so as to reduce the possibility of solidification of the asphalt particles inside the storage tank 2. After that, the staff can adjust the outlet size of the lower end of the circulation pipe 31 according to the size of the road crack.

[0031] When adjusting the size of the outlet on the lower side of the circulation pipe 31, the staff can start the first servo motor 82. The first servo motor 82 will drive the screw rod 74 to rotate through its own operation, and the screw rod 74 will drive the threaded block 73 to move when it rotates. When the threaded block 73 moves, it will drive the connected telescopic rod 72 to move through its connection with the connected telescopic rod 72. The connected telescopic rod 72 itself is not easy to be extended and retracted to achieve movement when moving. While moving, the blocking block 71 can also be pulled to rotate the blocking block 71 around the fixed rod 76 to adjust the position of the blocking block 71. When the blocking block 71 rotates to different positions, the size of the outlet at the lower end of the circulation pipe 31 will also be different. The more the blocking block 71 rotates, the larger the size of the outlet at the lower end of the circulation pipe 31 will be. When the outlet size at the lower end of the circulation pipe 31 is adjusted to the required size, the staff can open the circulation pipe 31 through the valve body 32 to allow the asphalt particles inside the storage tank 2 to flow out from the inside of the storage tank 2.

[0032] At the same time, the push rod 5 and the universal wheel 42 push the bottom plate 1 and the circulation pipe 31 to move, so as to fill the road cracks, and the rotating pressure roller 6 can flatten the flowing asphalt particles while following the movement of the bottom plate 1. This can solve the problem that most existing road cracks are of different widths and the discharge pipe cannot adjust the size of the discharge port, so that when encountering narrower road cracks, more asphalt particles may be discharged, thereby causing the problem of waste of asphalt particles.

[0033] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the utility model according to the technical solution and improved ideas of the utility model, which should be included in the protection scope of the utility model.
