[0002] Road surface crack sealing devices are professional equipment used to repair road surface cracks, prevent water damage and erosion, and extend the service life of roads. Their core function is to achieve waterproof sealing and structural reinforcement by heating sealant and precisely injecting it into the cracks.

[0003] Currently, most existing road crack sealing devices involve directly filling cracks with a crack sealing machine, and then smoothing the sealed area with a coating device to ensure that the sealed area is relatively flat compared to other areas.

[0004] Currently, while existing road crack sealing devices can smooth out the crack sealing area, they tend to throw the asphalt used for sealing outside the sealing area during the smoothing process, resulting in a small number of bulges on the outside of the sealing area, which affects the road surface uniformity. Therefore, a road crack sealing device for road construction is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a road surface crack sealing device for road construction, which aims to improve the problem that the asphalt used for sealing road surfaces is easily thrown to the outside during the existing technology.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a road surface crack sealing device for road construction, including a crack sealing machine 1. The crack sealing machine 1 is a device for spraying asphalt onto the cracked area of ​​the road surface. It is an existing product and will not be described in detail here. A smoothing mechanism 2 is provided on the outside of the crack sealing machine 1. The smoothing mechanism 2 is used to smooth the asphalt sprayed by the crack sealing machine 1. The smoothing mechanism 2 includes a mounting shell 21. A concave block is provided on the left side of the mounting shell 21, and the concave area on the left side of the mounting shell 21 is used to fix it to the crack sealing machine 1. The outer wall of the mounting shell 21 is fixedly connected to the outer wall of the crack sealing machine 1.

[0032] Reference Figure 2 - Figure 4The inner and lower sides of the mounting shell 21 are provided with a pushing assembly 22, which is used to push asphalt. There are two sets of pushing assemblies 22, which are respectively set on the left and right sides of the paint output end of the crack sealing machine 1. The pushing assembly 22 includes a rotating rod 221, which is cylindrical in shape. The outer wall of the rotating rod 221 is provided with a threaded groove 222, which is located in the area below the mounting shell 21. The thread direction of the left threaded groove 222 is opposite to that of the right threaded groove 222. The bottom end of the rotating rod 221 is fixedly connected to a limiting block 223, which is annular in shape. The inner wall of the limiting block 223 is provided with a threaded protrusion that matches the shape of the threaded groove 222. The outer wall of the threaded groove 222 is threadedly connected to a threaded block 224, and the outer wall of the threaded block 224 is fixedly connected to a scraper 225, which is arc-shaped and is used to push asphalt.

[0033] Reference Figure 2 - Figure 4 The smoothing mechanism 2 also includes a drive assembly 23, which includes a motor 231. The motor 231 is a forward and reverse motor, and the number of forward rotations and the number of reverse rotations of the motor 231 are the same. The motor 231 is fixedly connected to the inner wall of the mounting housing 21. The output shaft of the motor 231 is fixedly connected to the top end of the left rotating rod 221. A gear 232 is fixedly connected to the outer wall of the left rotating rod 221. A gear 233 is rotatably connected to the inner wall of the mounting housing 21. Gear 232 and gear 233 are connected in series. The meshing mechanism ensures that when gear 1 232 rotates, it can drive gear 233 to rotate. Gear 3 234 is fixedly connected to the outer wall of the right rotating rod 221. Gear 233 meshes with gear 3 234. The meshing mechanism ensures that when gear 233 rotates, it can drive gear 3 234 to rotate. The diameter and number of teeth of gear 1 232 and gear 3 234 are the same. The relationship between the number of teeth and the size ensures that gear 1 232 and gear 3 234 can rotate simultaneously, at the same speed and in the same direction with the cooperation of gear 233.

[0034] Reference Figure 2 - Figure 4A limiting component 24 is provided on the lower side of the mounting shell 21. The limiting component 24 is used to limit the position of the scraper 225. The limiting component 24 includes a limiting rod 241. The upper end of the limiting rod 241 is fixedly connected to the lower surface of the mounting shell 21. The number of limiting rods 241 is set to four. The two limiting rods 241 on the left and the two limiting rods 241 on the right are symmetrically arranged about the center line of the left and right rotating rods 221. The distance between the left rear limiting rod 241 and the right rotating rod 221 is longer than the length of the scraper 225. When one scraper 225 contacts the front limiting rod 241, the other scraper 225 contacts the rear limiting rod 241. By setting the length, it is ensured that the limiting rod 241 can only limit a single scraper 225 and cannot hinder the rotation of the other scraper 225.

[0035] Working principle: When in use, the operator starts the equipment, so that the crack filling machine 1 injects asphalt into the crack or around the crack as it moves forward.

[0036] At the same time, motor 231 starts, which drives the left rotating rod 221 to rotate. The rotation of the left rotating rod 221 drives gear 1 232 to rotate, which in turn drives gear 233 to rotate in the opposite direction. Gear 233 then drives gear 3 234 to rotate, so that gear 3 234 can rotate at the same time, in the same direction and at the same speed as gear 1 232. Therefore, the two rotating rods 221 can rotate at the same time, in the same direction and at the same speed.

[0037] When the rotating rod 221 rotates, if the scraper 225 does not contact the limiting rod 241, the rotating rod 221 will drive the scraper 225 to rotate synchronously with it. If the scraper 225 contacts the limiting rod 241, the rotating rod 221 will first drive the scraper 225 to rotate. After rotating until it contacts the limiting rod 241, the scraper 225 cannot rotate. Therefore, when the rotating rod 221 continues to rotate, the rotating rod 221 will rotate relative to the threaded block 224. Since the threaded block 224 has a threaded protrusion that matches the outer wall of the threaded groove 222, the threaded block 224 will move up and down, and drive the scraper 225 to move up and down. Since the thread directions of the two threaded grooves 222 are opposite, when one scraper 225 moves upward, the other scraper 225 will inevitably move downward.

[0038] In summary, as scraper 225 rotates, it scrapes the outer asphalt to the center and then moves upward. While it moves upward, another scraper 225 moves downward and, after reaching the position in contact with the ground, rotates in the opposite direction to the first scraper 225, thereby scraping the asphalt from the outer side towards the center. At the same time as it scrapes the asphalt, the first scraper 225 also rotates back to its initial position when it first scraped the asphalt and continues to move downward after reaching that position. This process is repeated in a cycle, achieving the effect of scraping the asphalt towards the center of the gap. Furthermore, because the asphalt is smoothed while being scraped, it achieves the effect of smoothing the asphalt and preventing it from moving to the outer side of the scraped area.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
