DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0021] As shown in Figure 1 and Figure 2 The utility model provides road construction side finishing device's technical scheme, including equipment shell 2, equipment shell 2 is fixedly installed with handrail rod 1, and equipment shell 2 bottom is fixedly installed with movable wheel 3, and equipment shell 2 is fixedly installed with electric lift 4 in, and electric lift 4 is connected with finishing mechanism 5, and finishing mechanism 5 includes the positioning base 506 of fixed installation in the electric lift 4 terminal, and drive motor 503 one side is fixedly installed with blowing mechanism 6, and through the collaborative work of finishing mechanism 5 and blowing mechanism 6, user can easily and conveniently carry out accurate finishing work to road edge, greatly improves work efficiency.

[0022] As shown in Figure 2 and Figure 3 Finishing mechanism 5 includes the positioning base 506 of fixed installation in the electric lift 4 terminal, and drive motor 503 is fixedly installed on positioning base 506, and drive shaft 502 is fixedly installed on drive motor 503, and grinding wheel 501 is fixedly installed in the terminal of drive shaft 502, and motor bracket 504 and retainer 507 are fixedly installed on positioning base 506, and transmission shaft 505 is rotatably installed on retainer 507, and the output terminal of drive motor 503 is equipped with coupling, and one end of drive shaft 502 is fixedly installed on the output terminal of drive motor 503 through coupling.

[0023] Specifically, when the driving motor 503 is started, it will start to drive the driving shaft 502 to rotate. With the rotation of the driving shaft 502, it will further drive the grinding wheel 501 to rotate at high speed. Once the grinding wheel 501 reaches a high-speed rotating state, it can be controlled to extend the electric elevator 4, so that the high-speed rotating grinding wheel 501 is in contact with the protruding part at the edge of the road. Through this contact, the grinding wheel 501 can effectively grind the protruding part at the edge of the road, thereby achieving rapid trimming work on the edge of the road.

[0024] As shown in Figure 2 and Figure 4 , the blowing mechanism 6 includes an air inlet cylinder 601 fixedly installed on the positioning base 506, an air blowing nozzle 604 fixedly installed at the end of the air inlet cylinder 601, a positioning bracket 607 fixedly installed in the air inlet cylinder 601, a bearing seat 606 fixedly installed on the positioning bracket 607, an active shaft 602 rotatably installed in the bearing seat 606, and a fan blade 605 fixedly installed at the front end of the active shaft 602. The active shaft 602, the driving shaft 502 and the transmission shaft 505 are all provided with helical gears, and the helical gears are meshed with each other in pairs. The air inlet cylinder 601 is provided with a mounting hole 603 on the side wall, the bearing seat 606 is provided with a bearing, and the active shaft 602 is movably installed on the positioning bracket 607 through the bearing.

[0025] Specifically, during the trimming process, the driving shaft 502 drives the transmission shaft 505 to rotate. After being driven by the driving shaft 502, the transmission shaft 505 further transmits power to make the active shaft 602 start to rotate. The rotating action of the active shaft 602 is an important part of the whole process, because it will drive the fan blade 605 to rotate at high speed. When the fan blade 605 rotates at high speed in the air inlet cylinder 601, it will produce a strong disturbance effect, so that the airflow can be sprayed out at high speed through the air blowing nozzle 604. These high-speed sprayed airflows have significant cleaning ability and can effectively blow away the dust at the edge of the road. In this way, the user can more clearly observe whether the protrusions at the edge of the road have been ground flat, thereby ensuring the quality of the trimming work.

[0026] Working principle: when using the device, first need to push the whole device along the edge of the road, to ensure that the grinding wheel 501 and the protruding part of the road edge accurate alignment. Once the grinding wheel 501 and the protruding part of the road edge correct alignment, next can start the drive motor 503. Drive motor 503 once started, it will start to drive shaft 502 rotation. The rotation of the drive shaft 502 will further drive the grinding wheel 501 to high speed rotation state. Grinding wheel 501 in high speed rotation, can operate the electric lift 4 to extend, so that the high speed rotating grinding wheel 501 can be in contact with the protruding part of the road edge and grinding. In this way, the protruding part of the road edge can be quickly trimmed to make it smooth. In the process of trimming, the rotation of the drive shaft 502 will also drive the transmission shaft 505 rotation. The rotation of the transmission shaft 505 will make the activity axis 602 start to rotate. The rotation of the activity axis 602 will further drive the fan blade 605 high speed rotation. Fan blade 605 in the air cylinder 601 high speed rotation, will disturb the internal airflow, and through the blowing nozzle 604 to high speed jet. This high speed jet flow will effectively blow away the dust on the edge of the road, so as to facilitate the user to observe whether the protruding part of the road edge has been ground flat.
