Description

Technical Field

[0001] This utility model relates to the field of road maintenance technology, and more specifically, to a device for filling gaps in highway pavement. Background Technology

[0002] Highway pavements are prone to cracks due to loads and temperature changes. If not repaired in time, rainwater will seep in and erode the roadbed, exacerbating pavement damage and affecting driving safety. Therefore, crack repair is the key to highway maintenance.

[0003] Existing filling methods have obvious drawbacks: manual asphalt scooping with simple containers is inefficient, difficult to control the amount used, and the high temperature of the asphalt can easily burn workers; large crack sealing machines are efficient, but they are bulky, costly, and lack flexibility in repairing narrow road sections or small cracks, resulting in low overall efficiency.

[0004] Currently, there is a lack of equipment that balances low cost, portability, and efficiency, creating an urgent need for a road surface crack filling device with a simple structure to address these issues. Therefore, this invention proposes a road surface crack filling device. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a road surface crack filling device that is easy to operate, efficient, and has low maintenance costs.

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: The utility model relates to a road surface crack filling device, comprising two frames arranged symmetrically from left to right, a connecting rod fixedly connected to the frame at a lower position and a shaft rotatably connected to the frame at an upper position, an asphalt bucket connected in series on the shaft between the two frames, a nozzle extending upward at the rear end of the asphalt bucket, one end of the nozzle communicating with the outside and the other end communicating with the inside of the asphalt bucket, a handle provided above the asphalt bucket, a side plate connected between the handle and the asphalt bucket, and at least one row of rollers arranged at intervals from front to back at the bottom of the frame.

[0007] The present invention is further configured such that: a stop bar is provided at the front end of the asphalt barrel, and the two ends of the stop bar are respectively connected to a vehicle frame.

[0008] The present invention is further configured such that the side plates are arranged symmetrically on both sides of the asphalt bucket and the handle.

[0009] The present invention is further configured such that: a row of rollers arranged at intervals in front and behind are provided at the bottom of the frame.

[0010] The present invention is further configured such that the distance between two adjacent rollers on the same frame is equal.

[0011] In summary, this utility model has the following beneficial effects: 1. The hand-push design with rollers makes it easy to move, allowing operators to easily pour and fill while walking, significantly improving efficiency compared to manual labor; the device has a simple structure, requires no additional power, and has a manufacturing cost far lower than large equipment, greatly reducing the cost of small and medium-sized repairs.

[0012] 2. The tilted nozzle enables directional asphalt discharge, avoiding splashing and burns; the nozzle is close to the crack for precise injection, reducing waste and ensuring dense filling, delaying road damage and extending the maintenance cycle. Attached Figure Description

[0014] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0015] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0016] Example 1 See Figure 1 and Figure 2 As shown, the road surface crack filling device involved in this embodiment includes two frames 1 arranged symmetrically from left to right. A connecting rod 2 arranged lower is fixedly connected between the frames 1, and a shaft 3 arranged upper is rotatably connected between them. An asphalt bucket 4 is connected in series on the shaft 3 between the two frames. A nozzle 5 extending upward at the rear end of the asphalt bucket 4 is provided. One end of the nozzle 5 communicates with the outside and the other end communicates with the inside of the asphalt bucket. A handle 6 is provided above the asphalt bucket 4. A side plate 7 is connected between the handle 6 and the asphalt bucket 4. The side plate 7 is arranged symmetrically on both sides of the asphalt bucket and the handle. A row of rollers 8 arranged at equal intervals front to back is provided at the bottom of the frame 1.

[0017] When using the road surface crack filling device, first heat the asphalt to a molten state. After checking that all parts of the device are operating normally, pour the asphalt into the asphalt bucket (no more than two-thirds full). Operators should take appropriate safety precautions. Then, push the device to the beginning of the crack, adjusting its position so that the nozzle is aligned with the crack and close to the road surface. During operation, push the device forward at a uniform speed while slowly pressing down the handle to tilt the asphalt bucket, allowing the asphalt to flow into the crack through the nozzle. Fine-tune the bucket's tilt angle according to the crack's condition to control the injection volume. When encountering a crack corner, first reset the asphalt bucket before adjusting the device's direction. After filling a single section of crack, wait until no more asphalt flows from the nozzle before moving the device. After all work is completed, promptly clean the nozzle and bucket opening of any residual asphalt. Finally, wipe the device clean and store it in a dry, ventilated place. In narrow road sections, the device's flexibility allows for single-person operation. In low-temperature environments, the asphalt bucket can be preheated to ensure the asphalt's fluidity.

[0018] Example 2 See Figure 1 and Figure 2 As shown, the road surface crack filling device involved in this embodiment is further configured based on embodiment 1, wherein the front end of the asphalt bucket 4 is provided with a stop bar 9, and the two ends of the stop bar 9 are respectively connected to a vehicle frame 1.

[0019] In this implementation scheme, the stop bar is used as a limit for the tipping of the asphalt bucket.

[0020] The road surface crack filling device involved in this utility model is easy to move due to its hand-push design and rollers. Operators can easily pour and fill the cracks while walking, which significantly improves efficiency compared to manual labor. The device has a simple structure, requires no additional power, and has a manufacturing cost far lower than large equipment, greatly reducing the cost of small and medium-sized repairs. Furthermore, the inclined nozzle enables directional discharge of asphalt, avoiding splashing and burns. The nozzle is close to the crack for precise injection, reducing waste and ensuring dense filling, delaying road surface damage, extending the maintenance cycle, and has complete functions and strong practicality.
