Abstract
Description
Technical Field
[0001] The present application relates to the technical field of road construction equipment, and more specifically, to an asphalt spraying pipe. Background Art
[0002] Asphalt is a complex mixture with a wide range of applications. It is a widely used pavement structure binder in road engineering. It can be used in proportion with mineral materials of different compositions to build asphalt pavements of different structures. It is widely used in highways. In the process of road construction and repair, asphalt spray pipes are a common and necessary component of the equipment.
[0003] Most of the current spray pipes are fixed structures. For example, a Chinese patent (publication number CN213389601U) discloses an asphalt spray pipe, including a spray pipe body, a thread is provided on the inner wall of the upper end of the spray pipe body, a protective cover is provided on the upper part of the spray pipe body, a threaded rod is connected to the lower part of the protective cover, a cleaning chamber is provided inside the spray pipe body, a connecting rod is provided at the end of the threaded rod, a cleaning push block is magnetically connected to the end of the connecting rod away from the protective cover, a storage cover is provided on the side wall of the spray pipe body, a storage chamber is provided inside the storage cover, the storage chamber is divided into an upper storage chamber and a lower storage chamber, a partition plate is provided in the middle position of the storage chamber, an air pump is provided in the lower storage chamber, a rotating groove is provided on the pipe wall of the spray pipe body, a rotating shaft is provided in the rotating groove, a rotating shell is provided on the rotating shaft, a baffle is connected to the rotating shell, and a limit plate is provided in front of the baffle, and the cleaning push rod is pushed by the air pressure of the air pump to clean the asphalt sticking to the inner wall of the spray pipe.
[0004] With regard to the above-mentioned related technologies, the inventors believe that the current spray pipes are mostly fixed structures, and their spraying angles cannot be adjusted. When precise spraying at a certain point or multiple points is required, such as road repair operations, a large area of asphalt is usually sprayed directly on and around the repaired area to cover it, which not only causes waste but also affects the aesthetics of the road surface. Utility Model Content
[0005] In order to solve the above problems, the present application provides an asphalt spraying pipe.
[0006] The asphalt spraying pipe provided in this application adopts the following technical solution:

Moreover, the four branch pipes can all perform spraying operations, thus realizing multi-angle and multi-point spraying operations.
[0009] Furthermore, the auxiliary pipe is solid at the bottom and hollow at the top, and the two hoses are threadedly connected to the hollow part of the auxiliary pipe.

[0011] Furthermore, a spherical connector is fixedly connected to the lower end of the auxiliary tube, and the auxiliary tube is rotatably connected to the connecting seat through the spherical connector.
[0012] Through the above technical solution, the coordinated use of the spherical connector and the connector seat can ensure the flexibility of angle rotation to the greatest extent.
[0013] Furthermore, a damping plate is arranged between the spherical connector and the connecting seat.
[0014] Through the above technical solution, the setting of the damping plate can increase the friction between the spherical connector and the connector seat, ensuring that the current angle can be maintained after rotation adjustment.
[0015] Furthermore, every two of the branch pipes are threadedly connected to the second connector in an annular arrangement at intervals, and the branch pipes are retractable sleeve-type structures.
[0016] Through the above technical solution, the sleeve-type branch pipe can be adjusted in length to further meet the precision requirements of spraying operations.
[0017] Furthermore, a valve is provided on the branch pipe.
[0018] Through the above technical solution, each branch pipe can be controlled by a corresponding valve to meet the demand.

[0029] The following is combined with Figure 1-2 This application is described in further detail.
[0030] The present application embodiment discloses an asphalt spraying pipe, please refer to Figure 1 , comprising a main pipe 1, the upper end of the main pipe 1 is threadedly connected with a first connector 2, the middle part of the upper end surface of the first connector 2 is fixedly connected with a connecting seat 3, a secondary pipe 4 is rotatably connected in the connecting seat 3, the upper end of the secondary pipe 4 is threadedly connected with a second connector 5, four branch pipes 6 are threadedly connected on the side wall of the second connector 5, the upper end surface of the first connector 2 is located on both sides of the connecting seat 3 and is also threadedly connected with hoses 7, the upper ends of the two hoses 7 are threadedly connected to the upper part of the side wall of the secondary pipe 4, and the secondary pipe 4 is rotatably connected to the main pipe 1 through the cooperation of the first connector 2 and the connecting seat 3. In use, the spraying angle can be freely adjusted as needed, and the auxiliary pipe 4 is connected to four branch pipes 6 through the second connecting head 5. The four branch pipes 6 can all perform spraying operations, which can meet the precise spraying needs of a certain point or multiple points to a large extent, effectively avoid material waste, and reduce the damage to the aesthetics of the road surface caused by repair operations. The main pipe 1 and the first connecting head 2, the auxiliary pipe 4 and the second connecting head 2, the branch pipe 6 and the second connecting head 5, and the hose 7 and the auxiliary pipe 4 and the first connecting head 2 are all assembled by threaded connection, which is easy to disassemble and clean after use.
[0031] See also Figure 2 The auxiliary pipe 4 is solid at the bottom and hollow at the top. Two hoses 7 are threadedly connected to the hollow part of the auxiliary pipe 4. During the spraying operation, the asphalt enters the auxiliary pipe 4 from the hose 7 and then reaches the branch pipe 6 through the auxiliary pipe 4.
[0032] See also Figure 1 The lower end of the auxiliary pipe 4 is fixedly connected with a spherical connector 401, and the auxiliary pipe 4 is rotatably connected to the connecting seat 3 through the spherical connector 401. The coordinated use of the spherical connector 401 and the connecting seat 3 allows the auxiliary pipe 4 to rotate freely as needed, which can maximize the flexibility of angle rotation during the spraying operation.
[0033] See also Figure 2 A damping plate 402 is provided between the spherical connector 401 and the connecting seat 3. The provision of the damping plate 402 can increase the friction between the spherical connector 401 and the connecting seat 3, ensuring that the auxiliary pipe 4 can maintain the current angle to avoid slipping during operation after rotation adjustment.
[0034] See also Figure 1 Every two branch pipes 6 are threadedly connected to the second connector 5 in a ring shape at 90 degree intervals. The branch pipes 6 are a retractable sleeve structure. The 90 degree interval setting can ensure the radiation area of each branch pipe 6. At the same time, the branch pipes 6 of the sleeve structure can be adjusted in length to further meet the precision requirements of the spraying operation.
[0035] See also Figure 1A valve 601 is also provided on the branch pipe 6, and each branch pipe 6 can be controlled by the corresponding valve 601. The area where spraying operation is required is opened to cover the branch pipe 6 for spraying, and the rest are closed, which meets the needs of precise operation and avoids waste.
[0036] The implementation principle of an asphalt spray pipe in an embodiment of the present application is as follows: when in use, the asphalt material enters the first connecting head 2 from the main pipe 1, then enters the auxiliary pipe 4 through the hose 7, and is finally sprayed out through the branch pipe 6. During the process, the auxiliary pipe 4 can be rotated to adjust the angle according to actual needs, and the spraying angle can be freely adjusted as needed. The four branch pipes 6 can all perform spraying operations, which can meet the precise spraying requirements of a certain point or multiple points to a large extent, effectively avoid material waste, and reduce the damage to the aesthetics of the road surface caused by repair operations. At the same time, the branch pipe 6 with a sleeve-type structure can be adjusted in length to further meet the precise requirements of the spraying operation.
[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
