[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Embodiment

[0024] Referring to Figures 1-4 , the present utility model provides a technical solution: a road caulking device for road construction, including a handle rod 1, a feeding rod 2, a spraying nozzle 3, a sealant tank 14 and a feeding pipe 11.

[0025] In this embodiment, the handle rod 1 is a hollow cylinder. On both sides of the surface of the handle rod 1, handles 12 are symmetrically arranged. The handles 12 are semi-circular arcs. A square opening is provided in the middle of the handle rod 1. A control switch 13 is arranged in the opening. The control switch 13 is used to control the pump body on the back of the feeding rod 2. Its cross-section is slightly smaller than the square opening provided in the middle of the handle rod 1. At the same time, to ensure that the equipment will not be damaged due to dust entering the handle rod 1 through the gap between the square opening and the control switch 13 during construction, the control switch 13 is set as a double-layer rectangular structure. The cross-section of the lower rectangular structure is larger than the square opening, and sealing strips are arranged at the corners of the two-layer rectangular structure to ensure the sealing of the gap.

[0026] In this embodiment, the feeding rod 2 is cylindrical and has a hollow structure inside. The top is connected to the bottom of the handle rod 1. A groove 21 is provided at the bottom of the feeding rod 2. The size of the groove 21 is adapted to the positioning block 4; the top of the spraying nozzle 3 is connected to the positioning block 4 through a bellows 6. The positioning block 4 is slidably clamped in the groove 21 at the bottom of the feeding rod 2. A material channel 41 is provided at the top of the positioning block 4; a positioning spring 5 is arranged outside the spraying nozzle 3 and the positioning block 4. The positioning spring 5 is welded to the spraying nozzle 3 and the positioning block 4. In actual use, due to the high frequency of use of the bellows 6, several bellows of the same specification can be prepared as spare parts when the equipment leaves the factory.

[0027] The caulking agent box 14 is of a box structure. On the front of the box, two straps 15 are symmetrically arranged. The straps 15 can be made of leather or fabric materials, or can be made of soft chemical materials. In this embodiment, the method of filling cotton in cotton cloth is adopted; a pump body is installed on the back of the caulking agent box 14, and its form is similar to that of a student's schoolbag, which ensures the stability of the caulking agent box 14 during the construction process and can also save the physical strength consumption of workers.

[0028] One end of the feed pipe 11 is connected to the pump body, and the other end is longitudinally arranged through the top of the handle rod 1 to the bottom of the feed rod 2 and is connected to the material channel 41. The handle rod 1 and the feed rod 2 are sleeved outside the feed pipe 11.

[0029] The feed pipe 11 is inserted and connected to the pump body, and is inserted and connected and fixed to the material channel 41.

[0030] The spray nozzle 3 is of a hollow conical structure, and an opening is provided at the conical top. The size of the opening should not be too large to prevent the caulking agent from flowing too fast during use and making it difficult to control the amount of the caulking agent used.

[0031] The positioning springs 5 are all of conical structures. The two ends of the positioning springs 5 are respectively fixedly connected to the outside of the positioning block 4 and the spray nozzle 3. Its function is to ensure the elastic transmission of the positioning block 4 and the spray nozzle 3 during caulking.

[0032] The cross-sectional diameter of the handle rod 1 is larger than the cross-sectional diameter of the feed rod 2, making the whole structure in an inverted triangle shape.

[0033] The working principle of the present utility model:

[0034] First, the operator places the caulking agent to be filled into the caulking agent box 14, carries the caulking agent box 14 on the back through the strap 15, holds the handle rod 1 with one hand, holds the handle 12 with the other hand or holds the handle 12 with both hands at the same time, turns on the control switch 13, and under the action of the pump body on the back of the caulking agent box 14, the caulking agent is introduced to the spray nozzle 3 through the feed pipe 11 and the material channel 41.

[0035] Align the spray nozzle 3 with the crack and press it downwards. Through the elastic transmission of the external positioning spring 5 and the outside of the positioning block 4, when holding the handle rod 1 and filling the crack along the crack, the bottom of the conical spray nozzle 3 can intermittently approach the bottom of cracks with different depths, so that the caulking agent can be filled into cracks with different depths in sufficient amounts, ensuring that sufficient caulking agent can be filled into cracks of different types, different depths, and with curved side walls, so that the caulking agent filled at the top of the crack will not collapse, thus making the filling flat and improving the integrity of the road surface caulking. Finally, after caulking is completed, use a scraping plate to scrape flat the caulking agent overflowing during filling.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
