[0014] 1. In the present utility model, with the cooperation of the stirring mechanism and the flattening mechanism, first, the device can be moved more easily through four universal wheels, reducing the working intensity of the staff.

[0022] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0023] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0024] Embodiment 1, as Figures 1-4 shown, the present invention provides a crack filling device for highway maintenance, including a stirring mechanism 1, and a flattening mechanism 2 is fixedly installed on the top of the stirring mechanism 1;

[0025] The stirring mechanism 1 includes a bottom plate 101, a square hole 102 is opened on the top of the bottom plate 101, a handle 103 is fixedly installed on the top of the bottom plate 101, four universal wheels 104 are fixedly installed on the bottom of the bottom plate 101, a stirring bin 105 is fixedly installed on the top of the bottom plate 101, a hole 106 is opened on the top of the stirring bin 105, a feeding port 107 is opened on the top of the stirring bin 105, a rotating rod 108 is movably inserted into the inner wall of the hole 106, a helical blade 109 is fixedly sleeved on the outer surface of the rotating rod 108, a motor 110 is arranged on the top of the rotating rod 108, a hole 111 is opened on the outer surface of the stirring bin 105, a hose 112 is fixedly communicated with the inner wall of the hole 111, a valve 113 is arranged on the outer surface of the hose 112, and the output end of the hose 112 is fixedly communicated with a discharge pipe 114.

[0026] The effect achieved by the entire Embodiment 1 is as follows. First, the motor 110 is connected to the rotating rod 108, and the rotating rod 108 is fixedly connected to the spiral blade 109. When the motor 110 operates, it can drive the spiral blade 109 to rotate, stirring the asphalt in the mixing bin 105, enabling automatic material stirring, greatly reducing the time and effort required for manual stirring. This not only improves the efficiency of the filling work and shortens the construction period but also helps reduce the workload of personnel and the fatigue and work injury risks caused by long-term manual operation. The setting of the discharge pipe 114 makes it easier to insert the discharge pipe 114 into the crack, preventing asphalt waste.

[0027] Embodiment 2 is as follows Figures 2-4 As shown, the flattening mechanism 2 includes a support frame 201. A hole three 202 is opened at the top of the support frame 201. A hydraulic cylinder 203 is fixedly installed at the top of the support frame 201. A piston rod 204 is provided at the output end of the hydraulic cylinder 203. A connecting frame 205 is fixedly installed at the bottom of the piston rod 204. A hole four 206 is opened on the outer surface wall of the connecting frame 205. A connecting rod 207 is fixedly inserted into the inner surface wall of the hole four 206. A flattening roller 208 is movably sleeved on the outer surface wall of the connecting rod 207. The top of the bottom plate 101 is fixedly connected to the bottom of the support frame 201.

[0028] The effect achieved by the entire Embodiment 2 is as follows. When the device is in normal use, since the hydraulic cylinder 203 is connected to the piston rod 204, the piston rod 204 is fixedly connected to the connecting frame 205. A hole four 206 is opened on the outer surface wall of the connecting frame 205. A connecting rod 207 is fixedly inserted into the inner surface wall of the hole four 206. A flattening roller 208 is movably sleeved on the outer surface wall of the connecting rod 207. The connecting frame 205 is lowered by the hydraulic cylinder 203 to contact the crack filled with asphalt, and the device is pushed to make the flattening roller 208 roll on the ground, enabling the filling material to better bond with the road surface, forming a solid filling layer. This helps enhance the durability and stability of the filling material, extend its service life, and reduce the repeated repair work caused by the failure of the filling material.

[0029] Among them, both the motor 110 and the hydraulic cylinder 203 are prior arts, and their components and operating principles are publicly known technologies, so no further explanation will be given here.

[0030] Working principle: Firstly, when the device is in normal use, by holding the handle 103 and pushing the device, the four universal wheels 104 can run to make the device move more easily. It can be easily moved to the position where the crack needs to be filled. Whether on a flat road surface or in a complex road condition, the staff can conveniently push the device and quickly reach the working point. At the same time, since the universal wheels 104 can turn flexibly, the device can easily handle curves, slopes or narrow sections, making the positioning more accurate and convenient. Place the asphalt in the mixing bin 105. At this time, when the motor 110 runs, it can drive the rotating rod 108 to rotate, so that the spiral blade 109 rotates to stir the asphalt, and can automatically complete the mixing work of the asphalt without manual stirring, thus saving a large amount of time and labor costs. At the same time, due to the uniform mixing, it can also reduce the cost increase caused by material waste. Secondly, insert the discharge pipe 114 into the crack, then open the valve 113, and the asphalt enters the discharge pipe 114 through the hose 112 and enters the crack to fill the crack. After the asphalt is filled, close the valve 113 and clamp the hose 112 in the buckle on the outer wall of the mixing bin 105 to fix it on the outer wall of the mixing bin 105. Secondly, through the operation of the hydraulic cylinder 203, drive the piston rod 204 to extend and retract, so as to drive the connecting frame 205 to move, lower the connecting frame 205, and make the flattening roller 208 contact the ground. At this time, push the device to make the flattening roller 208 move back and forth on the just-filled ground to flatten it, and can compact the filling material to the same height as the surrounding road surface to ensure the flatness of the road surface after filling. This helps to reduce the bumps and vibrations during vehicle driving, improve driving comfort and safety, not only simplifies the work process, but also reduces the working time and improves the work efficiency.

[0031] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
