Example 2

As shown in fig. 11 to 14, which are schematic structural views of another embodiment of the protection device 41 in the present embodiment, the protection device 41 in the present embodiment is different from that in embodiment 1 in that: the end face of the protecting sleeve 43 in the protecting assembly 41 is provided with an open slot 431, the side face of the open slot 431 is in an L shape, in this embodiment, the open slot 431 is mutually matched to form a fixing slot 44 after the protecting sleeve 43 is enclosed, and the end faces of the protecting sleeve 43 are mutually attached to the bottom of the fixing slot 44.

As shown in fig. 15, 16 and 17, in this embodiment, the protective sleeve 43 used in combination with the drill rod 31 further includes a sliding sleeve 50 disposed on the drill rod 31, and the sliding sleeve 50 is sleeved on the drill rod 31 and can slide up and down along the height direction of the drill rod 31, and it should be noted that: the sliding sleeve 50 in this embodiment is only sleeved on the drill rod 31 and does not rotate along with the rotation of the drill rod 31, and the drill rod 31 does not interfere with the sliding sleeve 50 in the rotation process. In this embodiment, a key 52 is longitudinally disposed on a side wall of the sliding sleeve 50, the key 52 is fixed on the side wall of the sliding sleeve 50, the sliding sleeve 50 is further connected with a telescopic mechanism 51, and the telescopic mechanism 51 is sleeved on an outer side of the drill rod 31. In this embodiment, after the protection component 41 is enclosed outside the drill rod 31, the sliding sleeve 50 is inserted into the cavity enclosed by the protection component 41, wherein the bonding member 52 is inserted into the fixing groove 44, the telescopic mechanism 51 is in a compressed state, therefore, after the drill rod 31 completes the drilling work, the driving cylinder 10 is operated to pull the first traction rope 11, so as to pull the drilling mechanism 30 and the sliding component 14 to move upwards, the telescopic mechanism 51 in the compressed state enables the sliding sleeve 50 to be always inserted into the cavity enclosed by the protection component 41, the inner wall of the sliding sleeve 50 abuts against the side wall of the drill rod 31, impurities on the surface of the drill rod 31, such as soil, gravel and the like, can be scraped off during the upward movement of the drill rod 31, so as to clean the drill rod 31, and because the inner wall of the sliding sleeve 50 is in contact with the drill rod 31, the vertical lowering of the drill rod 31 is further ensured during the lowering process, the drilling effect is improved.

In this embodiment, the sliding sleeve 50 ensures that the drilling mechanism 30 descends vertically, and that the drill rod 31 cleans impurities in the upward movement process, and the specific steps are as follows:

the first step is as follows: the driving cylinder 10 is operated to drive the sliding block to slide upwards, the first traction rope 11 pulls the movable pulley assembly 13 to move upwards, so that the sliding assembly 14 slides downwards on the fixed frame 20, and the drilling mechanism 30 moves downwards;

the second step is that: after the drilling mechanism 30 moves downwards to enable the drill rod 31 to penetrate through the through hole in the fixing base 40, the protection component 41 is enclosed on the side wall of the drill rod 31, the protection component 41 forms a fixing groove 44 after being enclosed, the sliding sleeve 50 moves downwards to be inserted into a cavity formed by the protection component 41 in an enclosing mode, the bonding piece 52 is inserted into the fixing groove 44 in an inserting mode, the telescopic mechanism 51 is in a compression state, and the sliding sleeve 50 is guaranteed to be inserted into the cavity enclosed by the protection component 41 all the time;

and thirdly, after drilling is finished, the driving cylinder 10 works reversely to drive the drill rod 31 to move upwards, the inner wall of the sliding sleeve 50 is in contact with the side wall of the drill rod 31 to scrape impurities on the surface of the drill rod 31, the drill rod 31 is cleaned, and the drill rod 31 is convenient to maintain.

In this embodiment, in order to avoid scratches caused by friction between the drill rod 31 and the sliding sleeve 50 during the upward movement, a soft layer is disposed on the inner wall of the sliding sleeve 50, so that on one hand, impurities of the drill rod 31 can be cleaned, and on the other hand, scratches caused to the drill rod 31 are also avoided.

It should be noted that the telescopic mechanism 51 in this embodiment includes, but is not limited to, a telescopic spring, as long as the telescopic mechanism 51 can drive the sliding sleeve 50 to move downward, and after the sliding sleeve 50 is inserted into the cavity enclosed by the protection component 41, the telescopic mechanism 51 can also stabilize the sliding sleeve 50 in the cavity due to the elastic action.

While the invention has been described in further detail in connection with specific embodiments thereof, it will be understood that the invention is not limited thereto, and that various other modifications and substitutions may be made by those skilled in the art without departing from the spirit of the invention, which should be considered to be within the scope of the invention as defined by the appended claims.
