DETAILED DESCRIPTION
[0019] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work shall fall within the protection scope of the present utility model.
[0020] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation of the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. The following will further describe the present utility model in detail with reference to the accompanying drawings.
[0021] As Figure 1-4 shown, a troweling machine for road construction provided by the present utility model includes a support plate 1, a troweling mechanism 2 and a support mechanism 3. A hinge seat 4 is arranged on the top of the support plate 1, and a support rod 5 is hinged on the hinge seat 4. The support rod 5 is an H-shaped frame structure, and a bent handle 6 is arranged at the top end of the support rod 5. The support mechanism 3 is arranged below the middle part of the support rod 5; the support mechanism 3 includes an upper support 7, a lower support 8 and a support roller 9. Both the upper support 7 and the lower support 8 are C-shaped supports, and the C-shaped openings of the upper support 7 and the lower support 8 are arranged in opposite directions. The top end of the upper support 7 is fixedly connected to the support rod 5. The lower support 8 is located directly below the upper support 7. A limiting rod 10 is arranged on the top of the lower support 8. The top end of the limiting rod 10 movably penetrates through the bottom wall of the upper support 7. A limiting piece 19 is arranged at the top end of the limiting rod 10 to prevent the lower support 8 from disengaging from below the upper support 7. A spring 11 is sleeved on the limiting rod 10. One end of the spring 11 is connected to the upper support 7, and the other end of the spring 11 is connected to the lower support 8. The support roller 9 is rotatably installed at the bottom end of the lower support 8. When the bent handle 6 breaks away from the worker's hand, the support roller 9 contacts the ground for a certain support, and the setting of the spring 11 can slow down the impact force when the handle is released. The support mechanism 3 can play a certain hindering effect to avoid potential safety hazards caused by the worker being unable to re-grasp the handle.
[0022] As Figure 1-3As shown, an extension support plate 12 is provided on one side of the top of the support plate 1, a support 13 is provided on the extension support plate 12, a support 2 14 is provided at the bottom of the middle end of the support rod 5, and an electric telescopic rod 15 is hinged between the support 13 and the support 2 14. The electric telescopic rod 15 adjusts the angle of the support rod 5 by its own telescopic adjustment with the connection between it and the hinge seat 4 as the rotation center, thereby adjusting the angle of the handle, so that the user can use it more conveniently according to his own situation.
[0023] like Figure 1-3 As shown, the smoothing mechanism 2 includes a motor 16 and a smoothing blade 17. The motor 16 is installed at the center of the support plate 1. The output end of the motor 16 is set through the support plate 1. The smoothing blades 17 are connected to the output end of the motor 16 in a circular array. The motor 16 drives the smoothing blades 17 to rotate to smooth the ground concrete. A protective frame 18 is connected to the outer side of the support plate 1, and the protective frame 18 is covered above the smoothing blade 17.
[0024] When in use, first start the electric telescopic rod 15 to adjust the angle and height of the handlebar 6 on the support rod 5. The electric telescopic rod 15 adjusts the support rod 5 by its own telescopic adjustment, and adjusts the angle by taking the connection between it and the hinge seat 4 as the rotation center. After adjusting to a position where the user is comfortable to operate, the user holds the handlebar 6 to smooth the cement floor, and starts the motor 16. The motor 16 drives the smear 17 to rotate to smooth the ground concrete. When the handlebar 6 is out of the worker's hand, the support roller 9 contacts the ground to provide certain support, and the setting of the spring 11 can reduce the impact when the handle is off, thereby having a certain blocking effect, and avoiding safety hazards caused by the worker's inability to hold the handle again.
[0025] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
