Detailed Implementation

[0027] The following are specific implementation cases and appendices. Figures 1 to 3The present invention will be further described below, but the present invention is not limited to these embodiments.

The two ends of the shaft are rotatably connected to the two first support plates 15 respectively; the two cutting blades 17 are fitted on the outside of the first rotating shaft 16 and are located between the two first support plates 15; the two second support plates 18 are installed at the bottom of the lifting plate 14 and are located on the outside of the base plate 10, and are opposite to the first support plates 15; the second rotating shaft 19 passes through the two second support plates 18 in sequence, and the two ends of the second rotating shaft 19 are rotatably connected to the two second support plates 18 respectively; the soil breaking wheel 20 is fitted on the outside of the second rotating shaft 19 and is located between the two second support plates 18; the four universal rollers 21 are connected to the bottom of the base plate 10.

[0029] By installing the adjustment mechanism 11 on the base plate 10 and connecting the translation platform 12 to the adjustment mechanism 11, the adjustment mechanism 11 can drive the translation platform 12 to move, thereby adjusting the position of the translation platform 12; by installing the lifting mechanism 13 on the translation platform 12 and connecting the lifting plate 14 to the lifting mechanism 13, the lifting mechanism 13 and the translation platform 12 can move synchronously, thereby enabling the lifting mechanism 13 to drive the lifting plate 14 to move up and down, thereby adjusting the height of the lifting plate 14. By installing two first support plates 15 at the bottom of the lifting plate 14 and rotatably connecting the two ends of the first rotating shaft 16 to the two first support plates 15 respectively, the two first support plates 15 support the first rotating shaft 16, thereby enabling the first rotating shaft 16 to rotate between the two first support plates 15. By fitting two cutting blades 17 on the outside of the first rotating shaft 16, rotating the first rotating shaft 16 causes the two cutting blades 17 to rotate, thereby enabling the two cutting blades 17 to cut the road surface.

By installing two second support plates 18 at the bottom of the lifting plate 14 and rotatably connecting both ends of the second rotating shaft 19 to the two second support plates 18 respectively, the two second support plates 18 cooperate to support the second rotating shaft 19, allowing the second rotating shaft 19 to rotate between the two second support plates 18. By mounting the breaking wheel 20 on the outside of the second rotating shaft 19, the second rotating shaft 19 can drive the breaking wheel 20 to rotate, thereby enabling the breaking wheel 20 to break the road surface and process grooves on the road surface. At the same time, since the two second support plates 18 are located on the outside of the base plate 10, the breaking wheel 20 is also located on the outside of the base plate 10, making it easy for the breaking wheel 20 to align with the drawn grooves. By connecting four universal rollers 21 to the bottom of the base plate 10, the base plate 10 can move on the ground via the four universal rollers 21, thereby improving the mobility of the product.

[0031] By employing the above structure, positioning the two cutting blades 17 and the soil-breaking wheel 20 on the outer side of the base plate 10, and ensuring that the cutting blades 17 and the soil-breaking wheel 20 are aligned with the groove to be created, not only can the grooving accuracy of the product be improved, but the user experience can also be enhanced. By mounting the adjustment mechanism 11 on the base plate 10 and connecting the adjustment mechanism 11 to the translation stage 12, the adjustment mechanism 11 can drive the translation stage 12, the two cutting blades 17, and the soil-breaking wheel 20 to move, thereby ensuring that the cutting blades 17 and the soil-breaking wheel 20 are aligned with the groove to be created, further improving the grooving accuracy of the product.
