DETAILED DESCRIPTION

[0017] The following will be described in detail in combination with the accompanying drawings. Figures 1-6 The specific embodiments of the utility model are further described in detail.

[0018] Embodiment one, the technical scheme it solves is, in the use process, the stepping motor 6 and the cutting motor 11 can drive screw rod 5 and cutting blade 10 to rotate respectively, the stepping motor 6 drives screw rod 5 to move down with the feeding frame 7, and then cutting frame 8 together with cutting blade 10 etc. will move down with the feeding frame 7, and then the cutting blade 10 of high-speed rotation is cut down into the asphalt pavement, when cutting blade 10 is fed to the asphalt pavement suitable depth, stop the stepping motor 6, then the handle 23 of walking device is pushed to move the application, and then the cutting blade 10 of a certain depth in asphalt pavement will move, and then the cutting work on the pavement can be completed, the cooling device provided can cool the cutting blade 10 in working condition.The application has simple structure, is convenient to use, the cutting depth of cutting blade 10 can be adjusted by the rotation of screw rod 5, and has high practicability.

[0019] Embodiment two, on the basis of embodiment one, in the use process, in order to facilitate the long-term operation of the application, therefore, the battery 24 is arranged on the base plate 1 to power the cutting motor 11, the stepping motor 6 and the electric quantitative pump 17.In addition, the connecting mode of cutting blade 10 and rotating shaft 9 can adopt the connecting mode in the prior art, as long as it is convenient to disassemble, and the application will not be described in detail.

[0020] Specifically, during use, first start the cutting motor 11, the cutting motor 11 will drive the cutting blade 10 to rotate at high speed through the rotating shaft 9, and then the cutting blade 10 is cut downward into the asphalt pavement. When it is necessary to adjust the cutting depth, the step motor 6 on the cross beam 4 is started in forward rotation, the step motor 6 in forward rotation will drive the lead screw 5 in forward rotation, the lead screw 5 in forward rotation will drive the feeding rack 7 connected with it by threads, and the feeding rack 7 is vertically slidingly matched with the vertical rod 3 in the sink 2, so under the driving of the forward rotating lead screw 5, the feeding rack 7 will move downward along the vertical rod 3, the cutting rack 8 will move downward synchronously as the feeding rack 7 moves downward, and then the rotating shaft 9 together with the cutting blade 10 will also move downward synchronously, so that the cutting blade 10 rotating at high speed enters the asphalt pavement downward, the operator stops the step motor 6 according to experience after the cutting blade 10 enters the appropriate depth, and then the operator can move the application along the asphalt pavement by pushing the handlebar 23, the cutting blade 10 entering the asphalt pavement to a certain depth will move accordingly, and then further cutting operation can be carried out. The rotating speed of the step motor 6 of the application should not be too high to avoid the cutting blade 10 feeding downward too fast and causing damage. The protective cover 12 on the cutting rack 8 can block the gravel generated by cutting to avoid the gravel flying around and causing accidents, and the protective cover 12 can also avoid the cutting blade 10 flying out and injuring people after breaking and damaging.

[0021] Correspondingly, when the cutting is completed and it is necessary to lift the cutting blade 10 upward to make it separate from the asphalt pavement, it is only necessary to start the step motor 6 in reverse rotation.

[0022] In example three, on the basis of example two, before use of the application, a sufficient amount of clean water needs to be added to the water storage tank 13 through the water inlet 14. During the operation of the cutting blade 10, the cooling device should also be started, specifically: open the drain valve 16 and start the electric quantitative pump 17, under the action of the electric quantitative pump 17, the clean water in the water storage tank 13 will flow to the cooling hose 18 at a certain flow rate through the drain pipe 15, and then be sprayed onto the cutting blade 10 from the nozzle 19, thereby cooling the cutting blade 10. The electric quantitative pump 17 can supply clean water to the cooling hose 18 at a certain flow rate to avoid waste caused by excessive water flow. The walking device includes walking wheels 21 installed on a walking support 20, and a handlebar fixedly connected with a push rod 22, under the action of the walking wheels 21, the operator can move the application by pushing the handlebar.
