[0027] See also Figure 1-Figure 5The utility model provides a road maintenance caulking device, including a barrel 1, a rectangular discharge port 11 communicating with the inside of the barrel 1 is provided at the bottom of the barrel 1, a guide groove 12 penetrating the inside of the rectangular discharge port 11 is provided on one side of the rectangular discharge port 11, a blocking plate 2 for blocking the inside of the rectangular discharge port 11 is slidably installed in the guide groove 12, the blocking plate 2 is located between the end surface in the rectangular discharge port 11 and the inner wall of the rectangular discharge port 11 to form a discharge gap 01 for asphalt to pass through, an adjusting device 4 is provided on the barrel 1, the adjusting device 4 is used to drive the blocking plate 2 to perform translational adjustment to adjust the size of the discharge gap 01, and a vertical pole 3 extending upward is fixed on the top of the barrel 1.

[0028] When the caulking machine provided by the utility model is used, the lower end of the rectangular discharge port 11 is facing the gap of the road surface, and the asphalt in the caulking machine is pumped into the barrel 1, and then flows from the barrel 1 to the rectangular discharge port 11, and finally discharged from the discharge gap 01 into the gap, so as to fill the gap. When caulking, according to the different sizes of the gaps, the sealing plate 2 is driven to slide and adjust along the guide groove 12 to both sides by operating the adjustment device 4, so as to change the size of the discharge gap 01 and adjust the discharge amount, so as to ensure that the discharge amount of the caulking machine can be adaptively adjusted according to the size of the gap, and the practicability is high.

[0029] Specifically, the adjusting device 4 includes a connecting arm 41, a bracket 42, a guide rod 43, a return spring 44 and a push mechanism 45. The connecting arm 41 is vertically fixed on the upper surface of the blocking plate 2, the bracket 42 is fixed on the top of the barrel 1, and a guide hole 421 with two ends passing through is provided on the bracket 42. The guide rod 43 is slidably installed in the guide hole 421. One end of the guide rod 43 is fixed to the top of the connecting arm 41. The return spring 44 is sleeved on the outside of the guide rod 43. One end of the return spring 44 is fixed to the connecting arm 41, and the other end is fixed to the bracket 42. The push mechanism 45 is arranged above the barrel 1, and is used to push the guide rod 43 to slide along the guide hole 421 toward one side of the connecting arm 41. The guide rod 43 is pushed to move toward one side of the connecting arm 41 by operating the push mechanism 45. At this time, the return spring 44 is compressed and stores energy, and under the connecting action of the connecting arm 41, the blocking plate 2 is driven to slide synchronously, so that the discharge gap 01 becomes larger, and the push on the guide rod 43 is cancelled by operating the pushing mechanism 45. Under the elastic returning action of the return spring 44, the guide rod 43 is driven to slide and reset. Under the connecting action of the connecting arm 41, the blocking plate 2 is driven to slide and reset. In this process, the discharge gap 01 becomes smaller, and the size of the discharge gap 01 is adjusted. The elastic force of the return spring 44 is used to finally restrain the end face of the blocking plate 2 from fitting closely to the inner wall of the rectangular discharge port 11, and the inside of the rectangular discharge port 11 is completely blocked. When the filling is completed and the transfer equipment is completed, the residual asphalt in the barrel 1 and the rectangular discharge port 11 can be prevented from dripping onto the road surface and causing pollution.

[0030] Specifically, the pushing mechanism 45 includes a cantilever 451, a threaded rod 452, a first wedge block 453 and a second wedge block 454. The cantilever 451 is fixed to the side of the vertical rod 3. The cantilever 451 is provided with a threaded hole 4511 that passes through the cantilever 451. The threaded rod 452 is threadedly installed in the threaded hole 4511. The first wedge block 453 is installed at the bottom end of the threaded rod 452. The second wedge block 454 is fixed to the end of the guide rod 43 away from the connecting arm 41. The second wedge block 454 is pressed and matched with the inclined surface of the first wedge block 453. By loosening the threaded rod 452 in the forward direction, the first wedge block 453 is pushed downward under the action of threaded engagement with the threaded hole 4511, and the inclined surface of the first wedge block 453 squeezes the second wedge block 454 and pushes the guide rod 43 to slide. At this time, the reset spring 44 is compressed. When the threaded rod 452 is screwed in the reverse direction, the first wedge block 453 can be moved upward. Under the action of the reset spring 44, the sealing plate 2 is driven to slide and reset. After the first wedge block 453 and the second wedge block 454 are safely separated, the sealing plate 2 safely blocks the rectangular discharge outlet 11.

[0031] Specifically, the bottom end of the threaded rod 452 is rotatably connected to the first wedge block 453, so that the threaded rod 452 and the first wedge block 453 have the ability to rotate relative to each other. A vertically extending limit rod 4531 is fixed to the top of the barrel 1, and a sliding block 4532 is slidably sleeved on the limit rod 4531. The sliding block 4532 is fixedly connected to the side of the first wedge block 453. The sliding cooperation between the limit rod 4531 and the sliding block 4532 is used to guide and limit the first wedge block 453, so as to prevent the rotating threaded rod 452 from driving the first wedge block 453 to rotate, causing the first wedge block 453 and the second wedge block 454 to be misaligned and unable to perform the inclined surface extrusion effect.

[0032] Specifically, a handle 4521 is fixed to the top of the threaded rod 452, and anti-slip grooves are provided on the outer peripheral wall of the handle 4521. By pinching the handle 4521, it is convenient to exert force to twist the threaded rod 452. The anti-slip grooves increase the friction between the handle 4521 and the hand to prevent the handle from slipping when twisting.

[0033] Specifically, a hand-held handle 31 is fixed to the side of the vertical pole 3 above the cantilever 451, and a rubber pad is sleeved on the outside of the hand-held handle 31. By holding the hand-held handle 31, the entire caulking device can be conveniently operated by hand. In addition, the rubber pad arranged on the outside of the hand-held handle 31 is soft and elastic, which has a buffering and protective effect on the hands and also has an anti-slip effect.

[0034] Specifically, the side of the barrel 1 is connected to a delivery pipe 101, and the end of the delivery pipe 101 is connected to the output port of the asphalt booster pump. Through the operation of the asphalt booster pump, the heated asphalt in the caulking machine can be pumped into the delivery pipe 101, and then the delivery pipe 101 can deliver the asphalt to the barrel 1, thereby realizing the supply of asphalt.

[0035] Specifically, the return spring 44 is made of high-carbon spring steel material, so that the return spring 44 has a higher elastic modulus and elastic limit, can quickly return to its original state after being subjected to external force, maintain the elastic properties of the spring, and ensure that the return spring 44 can withstand long-term cyclic loading without being easily deformed or broken, thereby increasing the service life of the return spring 44.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
