[0030] Wear-resistant plates 4 are fixedly connected to the base rod 1, the middle rod 2 and the head rod 3 respectively. The wear-resistant plates 4 are distributed in a circular array around the axis on the surface of the base rod 1, the middle rod 2 and the head rod 3.
[0031] The reinforcing ribs 5 are fixed on the surface of the wear-resistant plate 4. The reinforcing ribs 5 are evenly distributed and reinforce the wear-resistant plate 4, making the wear-resistant plate 4 less prone to deformation and improving the service life of the wear-resistant plate 4.
[0032] The base rod 1, middle rod 2, and head rod 3 are used in combination. The base rod 1, middle rod 2, and head rod 3 rotate with the wear-resistant plate 4. The wear-resistant plate 4 grinds irregular structures such as protrusions or probe stones on the hole wall to ensure that the hole wall is smooth and regular, and to avoid the drill bit getting stuck. The base rod 1, middle rod 2, and head rod 3 can be separated to reduce the difficulty of transporting the device. The drill bit rotates at low speed and flushes with flushing fluid to remove silt such as drill powder and collapsed rock cuttings from the bottom of the hole and restore the smoothness of the borehole.
[0033] In this embodiment, as Figure 1 and Figure 3 As shown, a front end 6 is fixedly connected to one end of the head rod 3, and a mating groove 7 is provided on the surface of the front end 6;
[0034] The front end 6 is made to reduce its diameter so that the head rod 3 can be easily inserted into the hole. When making the front end 6, the end face of the head rod 3 can be cut with a mating groove 7 first, then the root of the front end 6 is heated and then bent.
[0035] In this embodiment, as Figures 1-4As shown, a first threaded connection port 8 is provided on the inner wall of one end of the base rod 1, a first threaded connection head 9 is provided on one end of the middle rod 2, and the inner wall of the first threaded connection port 8 is threadedly connected to the first threaded connection head 9.

A second threaded connection head 11 is provided on one end of the head rod 3, and the inner wall of the second threaded connection port 10 is threadedly connected to the second threaded connection head 11. The base rod 1 and the middle rod 2 are connected together by the cooperation of the first threaded connection port 8 and the first threaded connection head 9, and the middle rod 2 and the head rod 3 are connected together by the second threaded connection port 10 and the second threaded connection head 11.
[0036] In this embodiment, as Figures 1-4 As shown, the surface of the base rod 1 is provided with a first slurry outlet hole 12, which is distributed at both ends of the wear-resistant plate 4. The surface of the base rod 1 is provided with a second slurry outlet hole 13, which is distributed at both ends of the wear-resistant plate 4. The surface of the base rod 1 is provided with a third slurry outlet hole 14, which is distributed at both ends of the wear-resistant plate 4. The first slurry outlet hole 12, the second slurry outlet hole 13, and the third slurry outlet hole 14 are widely distributed and there are multiple of them, so that the first slurry outlet hole 12, the second slurry outlet hole 13, and the third slurry outlet hole 14 are not easily blocked.
[0037] In this embodiment, as Figures 1-4 As shown, the working principle of the card slot scanning device provided in this embodiment is as follows:
[0038] The base rod 1 and the middle rod 2 are connected together by the first threaded connection port 8 and the first threaded connection head 9. The middle rod 2 and the head rod 3 are connected together by the second threaded connection port 10 and the second threaded connection head 11. The base rod 1, the middle rod 2 and the head rod 3 are used in combination. The base rod 1, the middle rod 2 and the head rod 3 rotate with the wear-resistant plate 4. The wear-resistant plate 4 grinds the irregular structures such as protrusions or probe stones on the hole wall to ensure that the hole wall is smooth and regular and to avoid the drill bit getting stuck. The base rod 1, the middle rod 2 and the head rod 3 can be separated to reduce the difficulty of transporting the device. The drill bit rotates at low speed and flushes with flushing fluid to remove the silt such as drill powder and collapsed rock cuttings at the bottom of the hole and restore the smoothness of the borehole.
