Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a road construction filling device that improves the smoothness of asphalt cold patch material supply, reduces manual operation, and increases the efficiency of road filling and repair.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a road construction leveling device, comprising a frame, a hopper mounted on the frame, and a flat tamping mechanism. Two casters are mounted on one side of the bottom of the frame, and the flat tamping mechanism is hinged to the side of the frame away from the casters. The bottom of the casters is flush with the bottom of the flat tamping mechanism. The bottom of the hopper is provided with a discharge pipe communicating with the inside of the hopper. The flat tamping mechanism provides vibration power for the frame vibration and for compacting the asphalt cold patch material.
[0007] Preferably, a leveling mechanism is installed at the discharge pipe.

[0016] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0017] As described in the background art, a road construction filling device is used to fill potholes in asphalt roads. Cold asphalt patching material is used for filling, but it has a certain degree of stickiness, which makes it difficult to discharge smoothly at the feeding mechanism. Cold asphalt patching material requires operators to vibrate and compact it, which is labor-intensive and inefficient.
[0018] To solve this technical problem, this utility model provides a road construction filling device, which is applied to the filling of potholes in asphalt roads.
[0019] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0021] Example 1 Please refer to Figure 1-3 A road construction leveling device includes: a frame 1, a hopper 2 mounted on the frame 1, and a flat tamping mechanism. Two casters 3 are mounted on one side of the bottom of the frame 1. The flat tamping mechanism is hinged to the side of the frame 1 away from the casters 3, and the bottom of the casters 3 is flush with the bottom of the flat tamping mechanism. The bottom of the hopper 2 is provided with a discharge pipe 4 that communicates with the inside of the hopper 2. The flat tamping mechanism provides vibration power for the frame 1 and is used for compacting the asphalt cold patch material.
[0022] For details, please refer to Figures 1-3 A cone frame 11 is fixedly installed inside the hopper 2, and a piercing cone 12 is fixedly installed on the top of the cone frame 11.
[0023] For details, please refer to Figure 1 A spring 13 is installed between the hopper 2 and the frame 1, and the hopper 2 and the frame 1 are elastically connected by the spring 13. Furthermore, one end of the spring 13 is fixedly connected to the hopper 2, and the other end of the spring 13 is fixedly connected to the frame 1. The spring 13 is a rigid spring with a certain supporting strength.
[0024] The road construction filling device provided in this embodiment can directly put bagged cold asphalt patch material into the cone frame 11 inside the hopper 2. Under the action of the piercing cone 12 and the cone frame 11, the packaging bag containing the cold asphalt patch material is punctured, eliminating the need for manual bag opening and reducing manual operation while further improving the efficiency of road pothole repair. When the flat plate leveling mechanism drives the frame 1 and the hopper 2 to vibrate, the spring 13 can improve the vibration effect of the hopper 2, so that the cold asphalt patch material in the hopper 2 can be discharged more smoothly through the discharge pipe 4, and at the same time, it is convenient for the cold asphalt patch material in the packaging bag to be fully discharged.
[0025] Example 2 The road construction grading device provided in Example 1 has been further optimized. For details, please refer to [link / reference]. Figures 3-4A leveling mechanism is installed at the discharge pipe 4. The leveling mechanism includes a cylinder frame 5 rotatably mounted on the discharge pipe 4, a paving blade 6 fixedly mounted on the cylinder frame 5, and a rotary drive component that provides power for the rotation of the cylinder frame 5. The centerline of the paving blade 6 coincides with the center axis of the cylinder frame 5. The rotary drive component includes a first motor 7 fixedly mounted on the frame 1 and a transmission component 8. The output end of the first motor 7 drives the cylinder frame 5 to rotate through the transmission component 8. Furthermore, the paving blade 6 divides the interior of the cylinder frame 5 into two semi-circular channels. The semi-circular channels allow the asphalt cold patch material to pass through without interfering with the feeding of the asphalt cold patch material. At the same time, it can ensure that the asphalt cold patch material in the potholes is fully paved, avoiding the formation of paving dead corners. The cylinder frame 5 is rotatably connected to the discharge pipe 4 through bearings, etc. The transmission component 8 can be a chain, gear set, transmission belt, or other equivalent component with transmission effect.
[0026] Specifically, the bottom of the paving blade 6 is 1-3cm higher than the bottom of the flat plate leveling mechanism.
[0027] For details, please refer to Figure 4 Multiple spiral guide vanes 9 are installed inside the cylinder frame 5, and the spiral guide vanes 9 are provided with leakage holes 10; the first motor 7 is a speed-regulating motor; furthermore, the first motor 7 can be a variable frequency speed-regulating motor, voltage-regulating speed-regulating motor or other equivalent motors with speed regulation effect.
[0028] The road construction leveling device provided in this embodiment allows cold asphalt patch material to fall into potholes on the road, forming a cone-shaped pile. A rotating drive unit rotates the cylinder frame 5 and the paving blade 6, which gradually level the cold asphalt patch material without manual intervention, further reducing manual labor and improving construction efficiency. The bottom of the flat-plate leveling mechanism is flush with the road surface, while the paving blade 6 is 1-3 cm higher than the bottom of the flat-plate leveling mechanism (the distance between the paving blade 6 and the ground can be adjusted appropriately according to the properties of the cold asphalt patch material). This ensures that the cold asphalt patch material is 1-3 cm higher than the road surface before being compacted. After the cold asphalt patch material is compacted, the upper part of the pothole is basically level with the road surface, which is suitable for asphalt... The compaction drop height of the cold patch material is pre-compensated with a height allowance. Due to the adhesiveness of the cold patch material, the spiral guide blade 9 can support the cold patch material at the discharge hopper 2 to prevent it from falling off by itself. When the cold patch material needs to be discharged, the first motor 7 drives the cylinder frame 5 to rotate, and the spiral guide blade 9 rotates with the cylinder frame 5. The spiral guide blade 9 produces a shoveling and conveying effect on the cold patch material, so that the cold patch material is discharged from the discharge pipe 4. The leakage hole 10 can increase the leakage amount of the cold patch material. The first motor 7 is a speed-regulating motor, which can adjust the speed of the spiral guide blade 9 to control the supply of cold patch material and avoid excessive supply of cold patch material.
[0029] Example 3 The road construction grading device provided in Example 2 has been further optimized. For details, please refer to [link / reference needed]. Figures 1-3 The flat tamping mechanism includes a tamping plate 14, a vibration driver and a power driver 15 mounted on the tamping plate 14. The vibration driver includes a housing 16, a rotating shaft 17 rotatably mounted inside the housing 16, and an eccentric hammer 18 fixedly mounted on the rotating shaft 17. The power driver 15 provides power for the rotation of the rotating shaft 17. A handle 19 is fixedly mounted on the tamping plate 14. Furthermore, the power driver 15 can be a diesel engine, a gasoline engine, or an electric motor, etc. The output shaft of the power driver 15 is connected to the rotating shaft 17 via a transmission belt, etc. The operator can control the direction of travel of the device through the handle 19.
[0030] For details, please refer to Figure 1 A lifting support mechanism is installed on the ramming plate 14. The lifting support mechanism includes a mounting base 20, a lifting seat 21 that is slidably mounted on the mounting base 20, a threaded screw 22 that is rotatably mounted on the mounting base 20, and a second motor 23 that provides power for the rotation of the threaded screw 22. The threaded screw 22 is threadedly connected to the lifting seat 21. A roller 24 is rotatably mounted on the lifting seat 21. Furthermore, the mounting base 20 is provided with a sliding groove, and the lifting seat 21 is slidably mounted in the sliding groove. The lifting seat 21 is provided with an internal threaded hole that fits with the threaded screw 22, and the threaded screw 22 is screwed into the internal threaded hole. There are multiple lifting support mechanisms.
[0031] The road construction leveling device provided in this embodiment has a power drive 15 that drives the rotating shaft 17 to rotate, and the rotating shaft 17 drives the eccentric hammer 18 to rotate. During the rotation, the eccentric hammer 18 generates eccentric force and drives the tamping plate 14 to vibrate up and down. During the vibration, the tamping plate 14 compacts and flattens the asphalt cold patch material in the pit. When the device needs to be moved as a whole, the second motor 23 drives the threaded screw 22 to rotate. After the threaded transmission, the lifting seat 21 moves downward, and the roller 24 contacts the ground and supports the tamping plate 14. This makes the tamping plate 14 separate from the ground, thereby improving the ease of movement of the device.
[0032] The process of using the road construction filling device provided by this utility model is as follows: Move the device to the top of the pothole on the road surface to be repaired, place the bagged asphalt cold patch material on the cone frame 11 in the hopper 2, puncture the packaging bag with the puncturing cone 12, drive the rotating shaft 17 and the eccentric hammer 18 to rotate with the power drive 15, the universal wheel 3 serves as the support point of the frame 1, and the flat plate leveling mechanism is hinged to the frame 1. After the flat plate leveling mechanism is started, it can synchronously drive the frame 1 and the hopper 2 on the frame 1 to vibrate. Under the action of vibration, the asphalt cold patch material in the hopper 2 enters the discharge pipe 4. The second motor 23 drives the cylinder frame 5 to rotate, and the spiral guide blade 9 transports the asphalt cold patch material in the discharge pipe 4 outward. The asphalt cold patch material falls into the pothole of the road, and the paving blade 6 can simultaneously spread the asphalt cold patch material. Then push the flat plate leveling mechanism to move towards the pothole filled with asphalt cold patch material, and flatten the asphalt cold patch material by the flat plate leveling mechanism.
