[0026] like Figure 1-5 As shown, the utility model provides a technical solution for a trowel machine for highway construction: a trowel machine for highway construction, including a support frame 1, and also including:
[0027] A control device, which is arranged on the support frame 1 and is used for finishing the highway concrete;
[0028] The control device includes a driving device 2, which is mounted on the top of the support frame 1, a trowel blade 3 is mounted on the output shaft of the driving device 2, a protective cover 4 is mounted on the outer side of the support frame 1, and a handlebar 6 is mounted on one side of the protective cover 4 through a fixing frame 5;
[0029] An adjusting device, which is arranged on the control device and is used to control the protection height of the protective cover 4;
[0030] Among them, the adjusting device includes a movable shaft 7, which is arranged inside the protective cover 4, an adjusting member 8 is installed at the bottom end of the movable shaft 7, a first spring 9 is sleeved on the outer surface of the movable shaft 7, a connecting shaft 10 is installed on the top of the movable shaft 7, and also includes a notch 11, the notch 11 is arranged on the fixed frame 5, a first fixed shaft 12 is installed inside the notch 11, a movable frame 13 is sleeved on the outer surface of the first fixed shaft 12, a second fixed shaft 14 is installed inside the notch 11, a movable plate 15 and a second spring 16 are sleeved on the outer surface of the second fixed shaft 14, a steel wire rope 17 is connected to one side of the movable plate 15, and a handle 18 is installed on the top of the steel wire rope 17.
[0031] Through the cooperation between the handle 18 and the steel wire rope 17, when the handle 18 moves, the movable plate 15 can be pulled by the steel wire rope 17 to move along the outer surface of the second fixed shaft 14, so that the movable plate 15 and the movable frame 13 can be driven to move upward along the outer surface of the first fixed shaft 12 and pull the connecting shaft 10 through the cooperation between the movable plate 15 and the movable frame 13. At the same time, through the cooperation between the movable shaft 7 and the protective cover 4, the adjusting member 8 will be driven to move upward, so that it can rise to avoid obstacles when blocked by hard objects, and the hard objects can be smoothed by the trowel blade 3.
[0032] like Figure 3 As shown, the first spring 9 is elastically supported between the adjusting member 8 and the protective cover 4 .
[0033] Through the design of the first spring 9, the adjusting member 8 has good elastic reset performance. At this time, since the first spring 9 is in a compressed state, an elastic force is applied to the adjusting member 8, thereby driving the adjusting member 8 to reset and protect the polishing blade 3.
[0034] like Figure 5 As shown, the bottom of the movable frame 13 is provided with a chamfer, and the movable plate 15 is in press contact with the movable frame 13 .
[0035] By setting the chamfer at the bottom of the movable frame 13, when the movable plate 15 presses the movable frame 13, the movable frame 13 will be driven to move upward along the outer surface of the first fixed shaft 12, so that the adjusting member 8 can be driven to move upward through the connecting shaft 10, so that it can avoid obstacles.

[0037] Through the design of the second spring 16, the movable plate 15 has elastic reset performance at both ends. At this time, since the second spring 16 is in a compressed state, it will apply an elastic force to the movable plate 15, thereby releasing the squeezing of the movable frame 13, so that the elastic force of the first spring 9 can drive the adjustment member 8 to reset.
[0038] like Figure 2 As shown, the top end of the connecting shaft 10 is connected to the movable frame 13 , and the movable frame 13 is sleeved on the outer surface of the supporting frame 1 .
[0039] Through the cooperation between the connecting shaft 10 and the movable frame 13, when the movable frame 13 moves upward along the outer surface of the first fixed shaft 12, the movable shaft 7 will be driven upward through the connecting shaft 10, so that the adjusting member 8 can be driven upward through the movable shaft 7.
[0040] like Figure 1 , 2 As shown, the handle 18 is slidably engaged with the handlebar 6 .
[0041] Through the cooperation between the handle 18 and the handlebar 6, when the handle 18 moves upward along the inside of the handlebar 6, the movable plate 15 will be pulled by the wire rope 17 to move along the outer surface of the second fixed shaft 14, so that the movable frame 13 can be driven by the movable plate 15 to move upward along the outer surface of the first fixed shaft 12.
[0042] like Figure 1 As shown, the adjusting member 8 is in a semi-ring shape and is arranged in the moving direction of the protective cover 4 , and the inner wall of the adjusting member 8 is slidably matched with the protective cover 4 .
[0043] Through the cooperation between the adjusting member 8 and the protective cover 4, when the movable shaft 7 moves upward along the inner side of the protective cover 4, the adjusting member 8 will be driven to slide upward along the outer side of the protective cover 4, thereby driving the adjusting member 8 to avoid hard objects.
[0044] Working principle:
[0045] First, the staff can push the handlebar 6 to control the trowel blade 3 to smooth the concrete along the road. When the road surface becomes hard and it is difficult to continue moving forward, the staff can pull the handle 18 to move upward along the inner side of the handlebar 6. Through the cooperation between the handle 18 and the steel wire rope 17, when the handle 18 moves, the movable plate 15 can be pulled by the steel wire rope 17 to move along the outer surface of the second fixed shaft 14, so that the movable frame 13 can be driven to move upward along the outer surface of the first fixed shaft 12 and pull the connecting shaft 10 through the cooperation between the movable plate 15 and the movable frame 13. At the same time, through the cooperation between the movable shaft 7 and the protective cover 4, the adjusting member 8 will be driven to move upward, so that it can rise and avoid obstacles when blocked by hard objects.
