[0050] It should be noted that the up and down direction mentioned in this article is the direction of gravity, and the left and right direction is the horizontal direction perpendicular to the up and down direction.

[0051] Example 1

[0052] like Figure 1 As shown, this embodiment provides a road surface cutting tool.

[0053] The road cutting tool arranged in this way supports the main body 11 to rotate around its central axis, which can drive the first cutting tooth 12 to cut the rock. The rock crushing efficiency is high, and after cutting the protruding rock, the crushed stone is easily dispersed, which can form a smoother road surface and is conducive to vehicle driving.

[0054] Preferably, multiple rows of first cutting teeth 12 are arranged in sequence on the side 111 around the central axis of the support body 11, and each row of first cutting teeth 12 extends at equal intervals along the central axis of the support body 11, and the distance between each adjacent row is equal. In this way, the tool has high cutting efficiency for rock.

[0055] Preferably, all the first cutting teeth 12 are arranged to be inclined toward the rotation direction of the support body 11 , and the angle between the first cutting teeth 12 and the tangent plane of the side surface 111 is 20° to 40°.

[0056] Preferably, the diameter of the support body 11 is 30-100 cm, and the length of the support body 11 is 100-400 cm.

[0057] Further, in this embodiment, the length of the support body 11 is 100 to 200 cm, and the middle of the length direction of the support body 11 has a first mounting position 112. In this way, when the length of the support body 11 is short, it is only necessary to set a mounting position in the middle of the length direction of the support body 11 to connect with the support member 7, so as to achieve stable support for the cutting tool.

[0058] Further preferably, a plurality of second cutting teeth are arranged around the central axis of the support body 11 on the first bottom surface, and a plurality of second cutting teeth are arranged around the central axis of the support body 11 on the second bottom surface.

[0062] The main difference between this embodiment and embodiment 1 is that:

[0063] like Figure 2 As shown, the length of the support body 11 is 200 to 400 cm, the middle of the length direction of the support body 11 no longer has the first mounting position 112, and the two ends of the length direction of the support body 11 respectively have the second mounting position 113 and the third mounting position 114. In this way, when the length of the support body 11 is long, by providing mounting positions at the two ends of the length direction of the support body 11 to connect with the support member 7, the cutting tool can be stably supported.

[0064] No second cutting teeth are arranged on the first bottom surface and the second bottom surface.

[0065] The rest of the contents are the same as those in Example 1 and will not be repeated here.

[0066] Example 3

[0067] The main difference between this embodiment and embodiment 1 is that:

[0068] The length of the support body 11 is 200 to 400 cm, and the two ends of the length direction of the support body 11 respectively have a second mounting position 113 and a third mounting position 114.

In this way, when the road-leveling tool moves along with the vehicle, the multiple flexible shielding plates 4 can bend and deform when they come into contact with the uneven road surface, further ensuring that the shielding plates 4 always keep in contact with the road surface, blocking the cutting debris without affecting the movement of the vehicle; and when the cutting debris hits the shielding plate 4, the shielding plate 4 made of a flexible material can better absorb the energy of the debris. Furthermore, the shielding plate 4 is made of rubber. In this way, the cutting debris hitting the shielding plate 4 will not make a loud sound, and the noise is low.

[0076] Preferably, each shielding plate 4 has a width of 20 to 50 cm, a height of 50 to 100 cm, and a thickness of 2 to 5 cm.

[0085] This embodiment provides a road surface cutting method, which is based on the road surface cutting tool described in any one of Embodiments 1 to 3 to cut the protruding rocks on the road surface, and includes the following steps:

[0086] S1. Identify rocks in the pavement operation area based on an image of the pavement operation area, and obtain the location distribution of the rocks in the pavement operation area.

[0087] Among them, based on the image of the road working area, the rocks in the road working area are identified, and the position distribution of the rocks in the road working area is obtained, including: inputting the image of the road working area into a rock detection model, identifying the rocks in the road working area and locating the positions of the rocks in the working area, and obtaining the position distribution of the rocks in the road working area.

[0088] Preferably, the rock detection model is a Faster R-CNN model with adapted weight parameters obtained through a pre-training process.

[0107] The pre-built objective function is:

[0108] F(x)=w1×N(x)+w2×V(x)+w3×T(x)+w4×R

[0109] Wherein, F(x) represents the comprehensive evaluation index or objective function value; w1, w2, w3 represent weight coefficients; N(x) represents the torque under cutting parameter x; V(x) represents the vibration frequency under cutting parameter x; T(x) represents the temperature under cutting parameter x; R represents the lithology data of the current cutting rock.
