[0031] The following is a clear and complete description of the technical solutions in the embodiments of the present invention, in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1

[0033] In existing technology, the press rollers of joint treatment equipment are typically equipped with scrapers to remove asphalt adhering to the roller surface. However, during the scraping process, asphalt can also adhere to the scraper surface, resulting in the scraper surface being covered with asphalt. As the equipment continues to operate, a large amount of asphalt clumps accumulate on the top of the scraper, which not only makes cleaning inconvenient but also affects the scraping efficiency of the scraper.

[0034] Therefore, in order to solve the above problems, the contact area between the scraper surface and the asphalt is reduced, so that when the equipment is in operation for a long time, asphalt lumps are not easily accumulated on the scraper surface, thereby reducing the frequency of scraper cleaning and improving the scraping efficiency of the scraper, the utility model discloses a portable joint processing device, refer to Figure 2 and Figure 4, including a rolling bin 3 and a mobile carrier 1, the rolling bin 3 is arranged on the mobile carrier 1; the inner cavity of the rolling bin 3 can rotatably set a rolling roller 4, wherein the bottom of the rolling bin 3 is provided with an opening for the lower end of the rolling roller 4 to pass through, and the lower end of the rolling roller 4 is used to contact the ground, wherein a scraper 5 is provided in the inner cavity of the rolling bin 3, and the length of the scraper 5 is adapted to the length of the rolling roller 4, and the scraper 5 is used to scrape the asphalt on the rolling roller 4, and one end of the scraper 5 is provided with a scraping end 13, and the scraping end 13 is used to contact the surface of the rolling roller 4; wherein, a discharge trough 14 is provided on the surface of the scraper 5, and the discharge trough 14 is used to collect the asphalt on the scraping end 13.

[0035] In this embodiment, when the rolling roller 4 starts to rotate on the asphalt ground and carries out the seam jointing operation, since the scraper end 13 is in contact with the surface of the rolling roller 4, as the rolling roller 4 rotates, the scraper end 13 can scrape off the asphalt lumps stuck on the surface of the rolling roller 4. At this time, due to the setting of the discharge groove 14, the asphalt scraped off by the scraper end 13 can fall back to the ground along the chip discharge groove 14, and then be flattened again by the rolling roller 4. At the same time, since the scraper 5 is arranged in a hollow structure, the contact area between the scraped asphalt and the scraper 5 is reduced, so that a large amount of asphalt is not easily accumulated on the surface of the scraper 5, thereby improving the scraping efficiency of the scraper 5.

[0036] In addition, since the scraped asphalt can fall back to the ground through the discharge trough 14 and be re-rolled by the rolling roller 4, the joint processing device proposed in this application can reuse the scraped asphalt, saving the use cost.

[0037] It should be noted that the mobile carrier 1 is a rectangular plate, the rolling bin 3 is placed horizontally on the mobile carrier 1, the rolling roller 4 is placed horizontally at the bottom of the mobile carrier 1, and connecting rods are provided at both ends of the opening of the rolling bin 3. The connecting rods are movably passed through the two ends of the rolling roller 4, so that the rolling roller 4 can rotate around the connecting rods.

[0038] In one embodiment, in order to allow the asphalt scraped off by the scraper end 13 to fall smoothly back to the ground from the discharge trough 14, the scraper end 13 is tilted at one end of the scraper 5, wherein the elevation angle of the scraper end 13 at the top of the scraper 5 is between 115 degrees and 125 degrees. Through this arrangement, the accumulated asphalt lumps can smoothly slide along the scraper end 13 into the discharge trough 14 under the action of gravity, which helps to reduce the accumulation of asphalt lumps at the scraper end 13.

[0039] It is worth mentioning that the end of the scraper end 13 that contacts the rolling roller 4 is set in a diamond shape, so as to reduce the surface area of ​​the scraper end 13 and prevent excessive asphalt blocks from accumulating on the scraper end 13. At the same time, it can also increase the sharpness of the scraper end 13, which helps to carry out the scraping operation smoothly.

[0040] Furthermore, in order to prevent the hollow scraper 5 from being deformed and damaged after long-term use, support rods 15 are provided on the inner walls on both sides of the discharge trough 14, wherein the support rods 15 are distributed parallel to the rolling roller 4. Through this arrangement, the support rods 15 can be connected to the hollow scraper 5 to support the scraper 5, thereby preventing the scraper 5 from being deformed due to external force.

[0041] Example 2

[0042] On the basis of the first embodiment, in order to make the joint treatment device be able to smoothly pour asphalt into the joints of the ground, refer to Figure 1-Figure 3 The present invention also includes an asphalt tank 2 and a stirring assembly. Specifically, the asphalt tank 2 is arranged on the top of the mobile vehicle 1, and the stirring assembly is arranged inside the asphalt tank 2, wherein the stirring assembly includes a driving member 6, a rotating shaft 11 and a stirring blade 12, the rotating shaft 11 is vertically arranged inside the asphalt tank 2, the driving member 6 is connected to the top end of the rotating shaft 11, and the stirring blade 12 is horizontally placed on the shaft body of the rotating shaft 11.

[0043] In this embodiment, the user can put the asphalt raw material into the asphalt tank 2, and then turn on the driving part 6, so that the stirring component in the asphalt tank 2 can continuously stir the asphalt raw material, thereby improving the fluidity of the asphalt raw material so that it can flow out of the asphalt tank 2 smoothly and be poured into the joints.

[0044] For example, the driving member 6 can be a rotary motor that is connected to the top of the rotating shaft 11 and can provide stable rotational power. The rotating shaft 11 is vertically arranged inside the asphalt tank 2, and its shaft body passes through the stirring blades 12, so that the stirring blades 12 can evenly stir the asphalt raw material. The stirring blades 12 are arranged horizontally, which helps to improve the uniformity and efficiency of the stirring. Therefore, through the above structure, the asphalt raw material can be fully mixed under the action of the stirring assembly, thereby improving its fluidity and ensuring that the asphalt can smoothly flow out of the asphalt tank 2 and be poured into the joints in the ground.

[0045] In another embodiment, the stirring blades 12 may employ a spiral structure, which further improves stirring efficiency and uniformity. Specifically, the spiral stirring blades 12 generate a strong axial flow, facilitating upward and downward circulation of the asphalt feedstock within the tank and ensuring thorough mixing. Furthermore, this spiral structure reduces resistance during the stirring process, lowering energy consumption and improving stirring efficiency.

[0046] Furthermore, the present application also includes a discharge pipe 7 for discharging the asphalt raw material in the asphalt tank 2, and a pouring head 10 for pouring the discharged asphalt raw material into the joint. Specifically, the top of the discharge pipe 7 is connected to the bottom of the asphalt tank 2, and the bottom of the discharge pipe 7 is passed through the mobile vehicle 1. The pouring head 10 includes an input port and an output port, wherein the input port is connected to the bottom of the discharge pipe 7, and the output port is arranged at the bottom of the mobile vehicle 1, wherein the filling head 10 and the rolling roller 4 are distributed parallel to each other at both ends of the bottom of the mobile vehicle 1.

[0047] Through this structure, after the asphalt raw material is evenly stirred, it can be directly transported to the injection head 10 through the discharge pipe 7. The asphalt raw material is then injected into the joint through the output port of the injection head 10. In addition, because the injection head 10 is arranged parallel to the rolling roller 4, it facilitates rolling while the asphalt is injected, thereby improving the efficiency and quality of the joint treatment.

[0048] It should be noted that a valve 9 is installed at the connection between the discharge pipe 7 and the input port. This valve controls the flow of the asphalt feedstock, ensuring that the asphalt flow rate can be adjusted as needed during the injection process. Furthermore, the valve 9 provides a seal to prevent asphalt leakage during storage or transportation. Specifically, the valve 9 can be a ball valve, a butterfly valve, or any other valve capable of controlling fluid flow, which will not be further described below.

[0049] Example 3

[0050] On the basis of the second embodiment, in order to prevent the blockage caused by the solidification of the asphalt raw material in the discharge pipe 7, refer to Figure 2 The utility model also includes a heating element 8 for continuously heating the discharge pipe 7. Specifically, a heating element 8 is provided on the outer tube wall of the discharge pipe 7, wherein the heating element 8 includes an electric heating wire, and the electric heating wire is sleeved on the outer tube wall of the discharge pipe 7.

[0051] In this embodiment, the heating element 8 is controlled by a host computer, which can adjust the heating power of the heating wire. This ensures that the asphalt raw material remains fluid in the discharge pipe 7 even in low-temperature environments, avoiding blockage caused by cooling and solidification.

[0052] Example 4

[0053] On the basis of the first and second embodiments, in order to make the seam processing device portable, refer to Figure 1 The top of the mobile vehicle 1 near one end of the rolling bin 3 is provided with a push-pull handrail, and the end point of the bottom of the mobile vehicle 1 is provided with a universal wheel.

[0054] In this embodiment, through the universal wheel setting, the staff can use the push-pull handrail to push the entire seam processing device, so that the device can be flexibly moved in different working environments and adapt to most terrains and ground conditions.

[0055] In addition, since the pouring head 10 is distributed in parallel at the other end of the rolling roller 4, when the device is pushed, the pouring head 10 will first pour the asphalt raw material into the joint, and then the rolling roller 4 will roll the joint, so that the asphalt raw material can be fully compacted after pouring, in the hope of improving the quality and durability of the joint.

[0056] In summary, in combination with Embodiments 1 to 4, the working steps of the portable seam processing device are as follows:

[0057] First, the asphalt raw material is poured into the asphalt tank 2, and the driving member 6 is started to start the stirring assembly to start working and evenly stir the asphalt raw material to maintain its fluidity.

[0058] Subsequently, the asphalt is transported to the pouring head 10 through the discharge pipe 7. Then, by operating the push-pull handrail moving device, it can be moved to the joint that needs to be poured.

[0059] Next, the pouring head 10 is operated to pour asphalt into the joints of the ground, and the rolling roller 4 is used to roll the asphalt to ensure that the joints are flat and dense.

[0060] Finally, during the process of rolling the road surface, the scraper 5 can scrape off the asphalt adhering to the surface of the rolling roller 4 and put the scraped asphalt back onto the ground through the discharge chute 14 so that it can be rolled again by the rolling roller 4.

[0061] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
