Technical Field

[0001] The invention relates to the technical field of asphalt spraying equipment, in particular to a spraying equipment for preparing nano-modified asphalt by a sol-gel method. Background Art

[0002] The on-site preparation of nano-modified asphalt by the sol-gel method and the spraying operation not only significantly improves the performance and durability of the road surface, but also greatly reduces construction costs and material waste. With the continuous development of nanotechnology and spraying technology, the application prospects of this operation method in the field of pavement engineering will be broader. In the future, with the further maturity and promotion of technology, nano-modified asphalt spraying operations will become one of the important choices for road construction and maintenance. During road construction, the modified asphalt will be sprayed on the road surface through spraying equipment to extend the service life of the road surface. The handheld spray gun is the equipment used for spraying.

[0003] Currently, when workers operate handheld spray guns, they typically drag the connected pipes directly onto the ground. When they need to move, they have to drag the long pipes along the ground. During this process, workers must maintain a firm grip on the gun to maintain steady control. The constant dragging of the long pipes undoubtedly places a heavy strain on their hands, leading to hand pain. Summary of the Invention

[0006] Specifically, the shield is in a trumpet-shaped structure, and a plurality of support plates are fixedly connected at equal intervals on one side of the shield with a smaller diameter. A groove is formed on the support plate, and a rotating plate is rotatably connected inside the groove.

[0007] Specifically, the rotating plate is closely attached to the side of the spray head of the spray gun body, and a rubber pad is fixedly connected to one side of the rotating plate closely attached to the spray head of the spray gun body.

[0008] Specifically, a positioning rod is movably passed through the upper end of the sleeve, and the positioning rod movably passes through the upper end of the clamping seat and the two hanging plates.

[0009] Specifically, the two connecting plates are symmetrically arranged with respect to the spray gun body, and both ends of the two connecting plates are rotatably connected to the spray gun body and the outer wall of the ferrule through a damping shaft.

[0010] Specifically, the ferrule has an arc-shaped curved surface structure, and the arc axis and the axis of the spray gun body are located on the same vertical plane, and an inner lining is fixedly connected to the inner wall of the ferrule.

[0018] like Figure 1-Figure 5 As shown, the present invention provides the following technical solutions: Example 1: A spraying device for preparing nano-modified asphalt by sol-gel method, wherein the nozzle of the spray gun body 1 is arranged at one end and a shield 4 is provided on the outside of the nozzle, and the handle of the spray gun body 1 is arranged at the other end and a pipe is connected to the handle.

[0019] The shield 4 has a trumpet-shaped structure and a plurality of support plates 5 are fixedly connected at equal intervals on one side with a smaller diameter. A groove 6 is provided on the support plate 5. A rotating plate 7 is rotatably connected inside the groove 6. The rotating plate 7 is tightly attached to the side of the nozzle of the spray gun body 1. The rotating plate 7 is tightly attached to the side of the nozzle of the spray gun body 1 and is fixedly connected to a rubber pad 8. By installing a shield 4 on the nozzle, it is convenient to block the splashed asphalt and prevent the spray gun body 1 from being contaminated.

[0020] When in use, connect one end of the pipe to the conveying equipment, fix the other end of the pipe on the handle of the spray gun body 1, put the shield 4 on the nozzle, and then rotate the rotating plate 7 to stick the rotating plate 7 to the side of the nozzle. The setting of the rubber pad 8 can ensure that the rotating plate 7 is difficult to automatically slide on the side of the nozzle, thereby preventing the shield 4 from detaching from the nozzle during use. When spraying asphalt, the shield 4 will block the splashed asphalt to prevent the splashed asphalt from contaminating the spray gun body 1.

[0021] Embodiment 2: The technical solution that distinguishes this embodiment from that of embodiment 1 includes: the other end of the spray gun body 1 is connected to a suspension mechanism 3 through two connecting plates 2, the suspension mechanism 3 includes a sleeve 31, one side of the upper end of the sleeve 31 is fixedly connected to a fixed frame 32, the other side of the upper end of the sleeve 31 is fixedly connected to a pull belt 33, the outer side of the pull belt 33 is fixedly connected to a fluff belt 34 and a hook belt 35, the middle part of the lower end of the sleeve 31 is fixedly connected to a holder 37, the lower end of the holder 37 is provided with a slot and is clamped to the pipe through the slot, the lower end of the sleeve 31 is symmetrically fixedly connected to two hanging plates 38 about the holder 37, a sleeve 39 is clamped between the two hanging plates 38, a rubber block 310 is fixedly connected to the inner wall of the lower end of the sleeve 39, and the upper end of the rubber block 310 is against the pipe.

[0022] Specifically, the upper end of the sleeve 39 is movably penetrated by a positioning rod 312, and the positioning rod 312 movably penetrates the upper end of the base 37 and the two hanging plates 38, which can fix the sleeve 39 on the base 37 so that the sleeve 39 cannot slide on the base 37 and the hanging plates 38.

[0023] Specifically, the two connecting plates 2 are symmetrically arranged about the spray gun body 1, and both ends of the two connecting plates 2 are respectively connected to the spray gun body 1 and the outer wall of the sleeve 31 through the damping shaft. The sleeve 31 can be connected to the spray gun body 1, and the angle of the sleeve 31 can be adjusted during the installation process.

[0024] Specifically, the ferrule 31 has an arc-shaped curved surface structure and the arc axis is located in the same vertical plane as the axis of the spray gun body 1. An inner lining 36 is fixedly connected to the inner wall of the ferrule 31 to prevent the edges of the ferrule 31 from scratching the skin of the worker's arm and causing discomfort when the ferrule 31 is put on the worker's arm.

[0025] Specifically, the sleeve 39 is sleeved on the outside of the card holder 37, and the internal shape of the sleeve 39 matches the outer shape of the card holder 37. Both sides of the sleeve 39 are fixedly connected with fixed blocks 311, which tightly sleeve the sleeve 39 on the card holder 37 and are not prone to loosening. The set fixed blocks 311 make it convenient for staff to grasp the sleeve 39.

[0026] Specifically, the velvet tape 34 and the hook tape 35 are arranged on the same surface of the drawstring 33, the hook tape 35 is close to the free end of the drawstring 33, and the area of the hook tape 35 is smaller than that of the velvet tape 34, which is convenient for controlling the tightness of the drawstring 33 and controlling the position of the hook tape 35 on the velvet tape 34.

[0027] When in use, the staff holds the handle of the spray gun body 1, and clamps the sleeve 31 under the forearm, passes the drawstring 33 through the fixing frame 32, folds the drawstring 33, sticks the hook surface belt 35 on the fluff belt 34, fastens the sleeve 31 to the forearm, clamps the pipe in the groove at the lower end of the holder 37, preliminarily fixes the pipe on the sleeve 31, puts one side of the sleeve 39 on the outside of the holder 37, and inserts it between the two hanging plates 38, then pushes the sleeve 39, covers the holder 37 through the sleeve 39, and completely inserts it between the two hanging plates 38, and this During the process, the rubber block 310 in the sleeve 39 will squeeze into the slot opening at the lower end of the holder 37 and rest against the pipe, fixing the pipe in the holder 37. The positioning rod 312 is then inserted into the hanging plate 38, the sleeve 39 and the holder 37 to prevent the sleeve 39 from sliding on the holder 37. Then the staff can start the asphalt conveying equipment, which will convey the asphalt into the spray gun body 1. The spray gun body 1 is turned on to spray the asphalt on the road surface. During the spraying process, the staff can swing their forearms and drag the pipe to slide on the ground to reduce the burden on the hand muscles.
