Description

Technical Field

[0001] This utility model belongs to the field of road repair technology, and specifically relates to an asphalt road repair device. Background Technology

[0002] Currently, asphalt road repair technology still widely employs the traditional method of manual paving combined with small plate compactors. This method has several drawbacks: First, it suffers from low construction efficiency, relying entirely on manual operation, which is not only labor-intensive but also significantly affected by the skill level of the workers, making it difficult to guarantee the uniformity of the asphalt distribution and often resulting in quality defects such as uneven thickness and inconsistent joints. Second, the compaction force and range of action of small plate compactors are limited, making it difficult to achieve a uniform and stable compaction effect, especially at the edges of the repair area where insufficient compaction is prone to occur, seriously affecting the durability and driving comfort of the repaired pavement. In addition, traditional methods have poor adaptability to the construction environment, making it difficult to guarantee construction quality under complex road conditions or special weather conditions, and also resulting in economic problems such as serious material waste and high energy consumption.

[0021] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only some embodiments, not all embodiments. Based on this embodiment, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figures 1 to 3 This embodiment provides an asphalt road repair device, including a chassis 1. The bottom of the chassis 1 is provided with a front pressure roller 2 and a rear pressure roller 3. The top of the chassis 1 is provided with a hopper 4. The bottom front side of the hopper 4 is provided with a discharge port. A feeding mechanism 5 is provided inside the hopper 4 near the discharge port. The discharge port is connected to a material spreading nozzle 7 through a material dispensing channel 6. A spreading plate 8 is provided on the outside of the spreading nozzle 7. The spreading plate 8 is connected to the chassis 1 through a connecting frame 9, and a telescopic mechanism 10 is provided between the connecting frame 9 and the chassis 1.

[0023] In this embodiment, the chassis 1 is also equipped with a power source, handrail, vibrator and controller, etc., which together with the front roller 2 and the rear roller 3 constitute the main body of the equipment. Its structure is the same as the main structure of the existing hand-held double steel drum road roller, and it can realize functions such as walking control and vibration compaction.

[0024] In this embodiment, the hopper 4 has a double-layer structure, with an inner layer made of stainless steel and an outer layer made of insulating material, which helps maintain the performance of the material and thus ensures construction quality. The bottom plate of the inner layer is inclined, which facilitates the flow of material towards the discharge port.

[0025] In this embodiment, the feeding mechanism 5 is arranged parallel to the discharge port and adopts a spiral feeding mechanism, wherein the spiral angles of the two spiral blades are opposite, thereby feeding the material on both sides to the middle discharge port, which is conducive to achieving continuous and uniform discharge.

[0026] In this embodiment, the discharge channel 6 is a pipe with an arc-shaped side, which facilitates the flow of materials. One end of the discharge channel 6 is welded to the discharge port, and the other end is welded to the feeding nozzle 7. Of course, it can also be designed as other detachable connection structures.

[0027] In this embodiment, the fabric nozzle 7 is shaped like a frustum, which is beneficial for achieving a better fabric application effect. Of course, it can also be designed into other shapes.

[0028] In this embodiment, the spreading plate 8 is composed of baffles on both sides and a baffle on the rear side. The baffles on both sides are arranged perpendicularly to the baffle on the rear side, which is beneficial to achieving a better spreading effect.

[0029] In this embodiment, the connecting frame 9 includes a first connecting rod fixedly installed on the rear of the spreading plate 8 and a second connecting rod distributed on both sides of the first connecting rod. The rear end of the second connecting rod is hinged to the side of the chassis 1, and the front end of the second connecting rod is fixedly connected to the end of the first connecting rod. There are two sets of telescopic mechanisms 10, distributed on both sides of the chassis 1. The upper end of each set of telescopic mechanisms 10 is hinged to the chassis 1, and the lower end is fixedly connected to the front end of the second connecting rod.

[0030] In this embodiment, the telescopic mechanism 10 can adjust the height of the spreading plate 8 off the ground, thereby adjusting the thickness of the spreading material to meet the needs of different road conditions while ensuring construction quality. Specifically, the telescopic mechanism 10 is a telescopic electric cylinder; of course, other forms of telescopic mechanisms can also be used.

[0031] The specific working process of this embodiment:

[0032] When repairing asphalt roads, start the equipment to move the front roller 2 and the rear roller 3 forward. At the same time, under the action of the feeding mechanism 5, the material in the hopper 4 flows through the discharge channel 6 to the material distribution nozzle 7, and then is distributed to the ground through the material distribution nozzle 7. At the same time, the material is spread by the spreading plate 8. When the front roller 2 and the rear roller 3 pass over the material, it is compacted.

[0033] Based on the above, it can be seen that the asphalt road repair equipment described in this utility model can integrate the functions of spreading, compacting and compacting as one unit, which can effectively improve the efficiency and quality of asphalt road repair, reduce the labor intensity of the construction process, and has strong adaptability.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
