DETAILED DESCRIPTION

[0027] 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.

[0028] In the prior art, asphalt caulking machines are typically equipped with at least one storage tank mounted on a mobile crane. A discharge pipe connects the storage tank to the caulking head on the crane, allowing the asphalt mixture to be poured into the pavement cracks. However, during periods of inactivity, the asphalt mixture in the storage tank can stagnate. Due to a lack of continuous heating and insulation, the mixture can partially solidify, leading to blockage in the tank's discharge port. This can negatively impact the asphalt quality and efficiency of subsequent caulking operations.

[0029] Example 1

[0030] Therefore, in order to solve the above problems and realize the function of improving asphalt quality and injection efficiency, the utility model discloses a discharge mechanism. Figure 1 、 Figure 3 and Figure 4, including a tray 6 and a distribution tray 7, the distribution tray 7 is arranged above the tray 6, wherein the top of the tray 6 is provided with a second rotating shaft 13, the distribution tray 7 is provided with a ring 16, the ring 16 is sleeved on the second rotating shaft 13, the second rotating shaft 13 is used to make the distribution tray 7 rotate on the top of the tray 6, wherein the surface of the tray 6 is provided with two discharge ports 15 relatively distributed along the second rotating shaft 13, the surface of the distribution tray 7 is provided with a solid layer 17 and a hollow layer 18 relatively distributed along the ring 16, the bottom of the two discharge ports 15 is respectively connected to a material guide trough 5, the two material guide troughs 5 are separated by the tray 6, the output ends of the two material guide troughs 5 are respectively connected to a discharge pipe 4, and the output ends of the two discharge pipes 4 are connected.

[0031] In this embodiment, the first rotating shaft 8 is used to drive the distribution plate 7 to rotate, so that the asphalt in the mixing tank can enter the corresponding discharge port 15 through the distribution plate 7, and then flow into the corresponding material guide trough 5 through the discharge port 15, and finally the asphalt is introduced into the discharge pipe 4 through the material guide trough 5 for unloading.

[0032] For example, in the initial state, the distribution plate 7 is in a stationary state, and the solid layer 17 and the hollow layer 18 are respectively attached to the top of the two discharge ports 15. At this time, the asphalt in the mixing tank will enter the discharge port 15 along the side of the hollow layer 18 on the surface of the distribution plate 7, and the solid layer 17 will prevent the asphalt from entering the other discharge port 15. When the asphalt solidifies in the current guide trough 5, the user can rotate the distribution plate 7 through the first rotating shaft 8 to exchange the positions of the solid layer 17 and the hollow layer 18, so that the asphalt can enter the other guide trough 5 through the other discharge port 15. Since the two guide troughs 5 are respectively connected to their respective discharge pipes 4, when the asphalt in one guide trough 5 solidifies, the solidified asphalt can be discharged through the corresponding discharge pipe 4. At the same time, the other guide trough 5 can still continue to receive new asphalt, thereby ensuring the continuity and efficiency of the unloading process.

[0033] In addition, due to the rotation of the material distribution plate 7, the two material guide troughs 5 can be used alternately so that they will not be blocked by solidified asphalt at the same time.

[0034] It should be noted that the second rotating shaft 13 is driven by an external motor, and the motor is controlled by a host computer.

[0035] Furthermore, in order to ensure that the solid layer 17 and the hollow layer 18 can completely fit with the corresponding discharge ports 15 , the length and width of any of the discharge ports 15 correspond to the length and width of the solid layer 17 and the hollow layer 18 .

[0036] In this embodiment, in order to enable the second rotating shaft 13 to better drive the distribution plate 7 to rotate, the distribution plate 7 is directly mounted on the second rotating shaft 13 through the ring 16, and the distribution plate 7 is restricted by the ring 16, so that the second rotating shaft 13 can apply traction to the distribution plate 7 and drive the distribution plate 7 to rotate.

[0037] In another embodiment, in order to improve the stability of the distribution disc 7 during rotation, a traction rod 14 is provided between the outer wall of the second rotating shaft 13 and the inner wall of the collar 16, and the traction rod 14 is used to drive the distribution disc 7 to rotate. Specifically, compared with directly sleeveing ​​the collar 16 on the second rotating shaft 13, due to the provision of the traction rod 14, the second rotating shaft 13 can drive the distribution disc 7 to rotate more smoothly, which helps to avoid the problem of idling of the second rotating shaft 13 and uneven rotation of the distribution disc 7.

[0038] Furthermore, in order to enable the asphalt to quickly pass through the guide trough 5 into the discharge pipe 4, the output end of any of the guide troughs 5 is tilted toward the corresponding discharge pipe 4. The tilted setting can speed up the asphalt discharge efficiency of the guide trough 5, and at the same time, avoid excessive asphalt accumulation on the surface of the guide trough 5 to a certain extent, thereby reducing the occurrence of blockage.

[0039] Example 2

[0040] On the basis of embodiment 1, in order to facilitate the use of the unloading mechanism, refer to Figure 1 and Figure 2 The present invention also discloses a mixture transportation and insulation device, comprising a mixture tank, a mobile carrier 2 and the unloading mechanism described in Example 1. Specifically, the mixture tank is arranged on the top of the mobile carrier 2, and the mixture tank comprises an outer tank 1 and an inner tank 10. The inner tank 10 is arranged inside the outer tank 1, wherein the inner tank 10 is used to store the mixture, and the unloading mechanism is built into the inner tank 10, wherein a pouring head 3 is provided at the bottom of the mobile carrier 2, and the pouring head 3 is used to be connected to the output ends of the two unloading pipes 4.

[0041] In this embodiment, the mobile vehicle 2 can be a vehicle with handles and pulleys. The user can push the mobile vehicle 2 to transport the mixture tank to the road surface to be repaired, and inject asphalt into the cracks in the ground through the injection head 3 at the bottom of the mobile vehicle 2.

[0042] It should be noted that the pouring head 3 is connected to the output ends of the two discharge pipes 4 at the same time, so that when the guide trough 5 used is switched due to the rotation of the distribution plate 7, the corresponding discharge pipe 4 can continue to perform the unloading operation.

[0043] The mixing tank is constructed with an outer tank 1 and an inner tank 10 nested within each other, which can help improve the tank's thermal insulation. Since the inner tank 10 directly contacts the mixture, its material must possess excellent thermal conductivity to ensure the mixture maintains an appropriate temperature during transportation. Furthermore, the insulating layer formed between the outer tank 1 and the inner tank 10 effectively reduces heat loss, further enhancing thermal insulation.

[0044] It can be understood that the outer tank 1 and the inner tank 10 are provided with communicating feed ports at the top, the feed ports are used to fill in new asphalt materials, and a sealing plug is provided in the feed ports.

[0045] Furthermore, a valve is installed at the connection between the injection head 3 and the discharge pipe 4. This valve controls the asphalt flow rate from the injection head 3, ensuring precise control of the crack width and depth during the injection process. By adjusting the valve opening, the user can flexibly control the injection speed and volume of asphalt, thereby improving the efficiency and quality of the repair work. The valve can be manual or electric to suit different operating environments and needs.

[0046] Furthermore, after the distribution disc 7 rotates, the material guide chute 5 that was previously blocked by solidified asphalt needs to be cleaned. A heating element 11 is provided between the outer tank 1 and the inner tank 10. The heating element 11 includes a heating wire, which is sheathed on the outer wall of the inner tank 10. A power supply for activating the heating element 11 is also provided inside the outer tank 1. The power switch is provided on the outside of the outer tank 1. When in use, the operator only needs to turn on the power switch on the outside of the outer tank 1 to activate the heating element 11. When the heating wire is energized, it will evenly heat the outer wall of the inner tank 10, thereby transferring heat to the mixture inside the inner tank 10.

[0047] In one embodiment, since the heating element 11 can heat the entire inner tank 10, as the caulking device is continuously used, the asphalt in the material guide trough 5 that is blocked due to asphalt solidification will be softened again and flow out from the caulking head 3 along the corresponding discharge pipe 4. Due to the obstruction of the solid layer 17, no new asphalt will enter the blocked material guide trough 5 until all the asphalt in the material guide trough 5 flows out. In this way, the unused material guide trough 5 can be kept unobstructed, so that the user can directly replace the material guide trough 5 through the dividing plate 7 when using the caulking machine next time, so that the two material guide troughs 5 can be used alternately and sustainably.

[0048] Therefore, through the above method, when using the caulking machine, the user only needs to rotate the material distribution plate 7 to directly use the material guide trough 5 that was not used last time. At the same time, as the caulking work proceeds, the solidified asphalt in the material guide trough 5 used last time will be softened again and flow out from the caulking head 3 together with the new asphalt this time, thereby saving preheating time and improving caulking efficiency.

[0049] Example 3

[0050] On the basis of the second embodiment, in order to fully heat the asphalt mixture in the inner tank 10, refer to Figure 1 The present invention also includes a stirring component for accelerating the fluidity of the mixture. Specifically, the stirring component is built into the inner tank 10 and is used to stir the mixture in the inner tank 10. The stirring component includes a first rotating shaft 8 and a stirring blade 9. The stirring blade 9 is arranged on the first rotating shaft 8, wherein the top of the second rotating shaft 13 is provided with a docking port 12, and one end of the first rotating shaft 8 can be rotatably inserted into the docking port 12.

[0051] In this embodiment, a driving member is provided at the other end of the first rotating shaft 8, and the driving member can be a motor. The motor can drive the first rotating shaft 8 to rotate in the docking port 12, thereby driving the stirring blades 9 to stir the asphalt mixture in the inner tank 10. In this way, the stirred mixture can be mixed more evenly, and the fluidity is increased, which is convenient for unloading and exporting. It can also increase the contact between the mixture and the inner wall of the inner tank 10, so that it can be heated evenly.

[0052] In summary, in combination with the first to third embodiments, the working steps of the unloading mechanism and the mixed material transport and heat preservation device are as follows:

[0053] First, the user can select an unblocked material guide chute 5 by rotating the material distribution plate 7 according to actual conditions.

[0054] Subsequently, the asphalt mixture is poured into the inner tank 10, and the heating element 11 is activated to heat the mixture in the inner tank 10 to ensure that the mixture maintains an appropriate temperature during the pouring process. The mixture in the mixing tank is thoroughly stirred by the stirring assembly to ensure the uniformity and fluidity of the mixture. The operator then transports the mixing tank to the repair road surface using the mobile vehicle 2, while ensuring that the pouring head 3 at the bottom of the mobile vehicle 2 is connected to the output end of the discharge pipe 4.

[0055] Next, the operator adjusts the valve at the injection head 3 according to the width and depth of the crack to control the asphalt flow rate and injection speed. During the injection process, the asphalt in the clogged guide trough 5 will soften and flow out due to the action of the heating element 11, while the unused guide trough 5 will remain unobstructed, facilitating the next use.

[0056] Finally, when the mixture in the mixing tank is completely poured, the operator turns off the heating element 11 and the stirring assembly, and moves the mixing tank and the mobile carrier 2 to a safe area for cleaning and maintenance, in preparation for the next use.

[0057] 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.

[0058] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
