[0002] Asphalt caulking machines are used for road maintenance and repair, filling cracks and gaps to prevent the intrusion of moisture and impurities, thereby extending the service life of the road. Asphalt caulking machines are equipped with heating, injection, and control systems. The heating system heats the asphalt to 150°C to 200°C to ensure its fluidity and adhesion; the injection device evenly injects the heated asphalt into the cracks to fill them.

[0003] Some asphalt caulking machines usually have a simple structure, with a fixed spraying area and spraying volume. At the same time, it is difficult to deal with the situation of nozzle blockage. The cracks on the road are of different sizes. If asphalt is poured into narrow gaps at a constant flow rate, it will cause waste. For larger gaps, the amount of asphalt poured is insufficient, resulting in reduced efficiency. The small pouring area also affects the pouring speed. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0027] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0028] Example 1:

[0029] See also Figure 1-7The utility model provides a technical solution: an asphalt caulking machine for road paving includes a pouring vehicle 1, an asphalt pipe 2 installed on the pouring vehicle 1, and a spray gun 3 installed on the asphalt pipe 2. The asphalt pipe 2 is provided with a control mechanism 4, a flow regulating mechanism 5, and a dredging mechanism 6. The dredging mechanism 6 is provided at the lower ends of the control mechanism 4 and the flow regulating mechanism 5, and the flow regulating mechanism 5 is provided on one side of the control mechanism 4.

[0030] Furthermore, the control mechanism 4 includes a motor protection cover 41, which is fixedly connected to one side of the spray gun 3. A stepper motor 42 is installed inside the motor protection cover 41, and a transmission tooth 43 is fixedly connected to the output end of the stepper motor 42. A switch 44 is installed on one side of the spray gun 3, and the stepper motor 42 is electrically connected to the switch 44.

[0031] Furthermore, the flow control assembly 51 includes a fixed cover 511, which is fixedly connected to the lower end of the asphalt pipe 2, and the upper end of the spray gun 3 is rotatably connected to the rotating plate 512. A baffle 513 is provided between the fixed cover 511 and the rotating plate 512, and one end of the baffle 513 is rotatably connected to the fixed cover 511 and the other end is slidably connected to the rotating plate 512. The rotating plate 512 is fixedly connected to the meshing teeth 514, and the meshing teeth 514 are meshed with the transmission teeth 43. The rotation of the stepper motor 42 is controlled by turning the switch 44, and the stepper motor 42 drives the rotating plate 512 to rotate. The rotation of the rotating plate 512 pushes or pulls the baffle 513 to slide in the rotating plate 512 during the rotation process. Driven by the rotating plate 512, the baffle 513 gradually opens or closes the asphalt passage inside the spray gun 3, and the asphalt flow rate can be adjusted according to the size of the crack.

[0032] Furthermore, the area adjustment component 52 includes a guide plate 521, which is fixedly connected to the lower end of the spray gun 3. A baffle 523 is fixedly connected to the side of the fixed cover 511 away from the meshing teeth 514. A guide pipe 522 is provided between the guide plate 521 and the asphalt pipe 2. When the rotating plate 512 drives the baffle 513 to move, the baffle 523 rotates synchronously with the rotating plate 512. When the asphalt passage inside the spray gun 3 increases, the opening on the baffle 523 connects the guide pipe 522. The asphalt liquid flows to the guide plate 521 through the guide pipe 522. The guide plate 521 increases the contact area between the asphalt liquid and the crack, thereby increasing work efficiency.

[0033] Furthermore, an opening is formed on the baffle 523 for controlling the communication state of the flow guide tube 522 .

[0034] Furthermore, a handle is installed on the spray gun 3.

[0035] The flow regulating mechanism 5 includes a flow control component 51 and an area regulating component 52 . The flow control component 51 is arranged on the inner side of the asphalt pipe 2 , and the area regulating component 52 is arranged on the outer side of the asphalt pipe 2 .

[0036] Example 2:

[0037] See also Figure 6 and Figure 7 , and combined with Example 1, it is further obtained that the dredging mechanism 6 includes a screw sleeve 601, which extends through the spray gun 3 to the inside of the spray gun 3 and is rotatably connected to the spray gun 3. A threaded sleeve 1 602 is rotatably connected to the inside of the spray gun 3. The screw sleeve 601 and the threaded sleeve 1 602 are fixedly connected with bevel teeth, and the screw sleeve 601 and the threaded sleeve 1 602 are engaged with the bevel teeth. The threaded sleeve 1 602 is internally threaded with a threaded sleeve 2 603, and the threaded sleeve 2 603 is internally threaded with a threaded column 604. The threaded column 604 cannot rotate. When there is a sticky blockage at the end of the spray gun 3, the screw sleeve 601 can be screwed, and the rotational force is transmitted to the threaded sleeve 1 602 through the screw sleeve 601. During the rotation of the threaded sleeve 1 602, the threaded sleeve 1 602, the threaded sleeve 2 603 and the threaded column 604 will all stretch, and the blockage on the spray gun 3 is dredged by the stretched threaded column 604. The threaded column 604 can be reset by twisting the screw sleeve 601 in the opposite direction.

[0038] During actual operation, when this device is used, a worker can hold the handle on the spray gun 3, and the asphalt liquid flows to the spray gun 3 through the asphalt pipe 2. The worker controls the position of the spray gun 3 to spray asphalt into the crack. If a larger crack is encountered during this period, the worker can turn the switch 44 to control the stepper motor 42 to rotate clockwise. The meshing teeth 514 rotate counterclockwise under the drive of the stepper motor 42, and the meshing teeth 514 drive the rotating plate 512 to rotate. During the rotation of the rotating plate 512, the baffle 513 is pulled away from the center of the rotating plate 512. This process will expand the center of the rotating plate 512. At the same time, the baffle 523 rotates counterclockwise synchronously, so that the hole on the baffle 523 is connected to the guide pipe 522. The asphalt liquid can then pass through the baffle 523 and reach the guide plate 521 through the guide pipe 522. The contact area between the asphalt liquid and the crack at the guide plate 521 is increased, thereby increasing the efficiency of the irrigation work.

[0039] When encountering small cracks, the required asphalt liquid will be reduced. The switch 44 can be turned to rotate the rotating plate 512 clockwise. The rotating plate 512 drives the baffle 513 to slide on the rotating plate 512 and approach the center of the rotating plate 512. The center of the rotating plate 512 is reduced in area of ​​the internal passage of the spray gun 3 due to the action of the baffle 513. At the same time, the baffle 523 is driven to cut off the internal passage of the guide tube 522, reducing the flow rate inside the spray gun 3 and saving the use of asphalt.

[0040] When the nozzle of the spray gun 3 encounters asphalt coagulation or blockage, the screw sleeve 601 can be screwed. Under the rotation of the screw sleeve 601, the threaded sleeve 603 and the threaded column 604 extend to clean the coagulated asphalt at the nozzle of the spray gun 3.

[0041] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.
