The joint drive rotating assembly is used to drive the four threaded drive assemblies to rotate synchronously when the first motor 13 is started, and to ensure that the two relative threaded drive assemblies rotate in opposite directions.

[0028] Furthermore, the inner diameter of the anti-collapse sleeve 200 is larger than the outer diameter of the round drill bit 2, and the outer diameter of the anti-collapse sleeve 200 is smaller than the outer diameter formed by the four telescopic blocks 4. This makes it convenient for the air supply to move upward from the inside of the anti-collapse sleeve 200 after the telescopic block 4 is retracted into the round drill bit 2, by utilizing the fact that the outer diameter of the round drill bit 2 is smaller than the inner diameter of the anti-collapse sleeve 200.

[0029] Furthermore, two transverse guide rods 7 are fixedly connected to the four sides of the fixed box 6, and the telescopic block 4 is slidably mounted on the corresponding two transverse guide rods 7, wherein the telescopic block 4 is provided with two transverse guide grooves that are respectively slidably mounted on the outer sides of the corresponding transverse guide rods 7 on one side close to the fixed box 6, and a limiting groove is provided at the bottom of the transverse guide rod 7, and a limiting block that is slidably connected to the corresponding limiting groove is fixedly connected to the inner wall of the bottom of the transverse guide groove, which plays the role of guiding the transverse sliding of the telescopic block 4 and limiting and preventing it from falling off.

[0032] The method of using this embodiment is as follows: when in use, the T-shaped connecting seat is connected to the external mobile vehicle equipment to be driven and displaced by the T-shaped connecting seat, and when it moves to the position where drilling is required, the driving motor 103 is used to drive the rotating tube 102 to rotate, and the electric slide rail 1 is used to drive the rotating tube 102 to move downward through the round seat 101, and the rotating tube 102 that moves downward and rotates is used to drive the round drill bit 2 to rotate, and the round drill bit 2 drives the four telescopic blocks 4 to rotate, and the four telescopic blocks 4 and the round drill bit 2 drive the multiple drill teeth 5 downward to perform drilling work, and when the four telescopic blocks 4 move downward, the anti-collapse casing 200 moves downward into the hole as a whole with the four telescopic blocks 4 under the action of their own gravity;

[0033] After the drilling is completed, when the round drill bit 2 needs to be removed, the personnel first use the external remote control to control the first motor 13 to start in the forward direction, so that it drives the first bevel gear 11 to rotate through the rotating shaft 12, and the first bevel gear 11 drives the four second bevel gears 10 to rotate synchronously. The two second bevel gears 10 are symmetrically arranged to achieve the opposite rotation directions of the two second bevel gears 10. The four second bevel gears 10 are used to drive the four screw rods 9 to rotate synchronously, and the rotation directions of the two screw rods 9 are opposite. When the four screw rods 9 rotate, they drive the four inner screw rods 9 to rotate. The threaded sleeve 8 shrinks and moves toward the middle, and the four internal threaded sleeves 8 drive the four telescopic blocks 4 to shrink into the round drill bit 2 through the four rectangular grooves 3, thereby removing the blocking restriction on the bottom of the anti-collapse sleeve 200. At this time, the round drill bit 2 can be directly moved upward from the anti-collapse sleeve 200, and the anti-collapse sleeve 200 is used to directly support and prevent collapse in the photovoltaic pile foundation hole formed after drilling, thereby avoiding the phenomenon that the debris formed after drilling in geology such as gravel and goose warm stone is easy to collapse toward the middle and cause blockage of the hole, thereby ensuring that the pile foundation hole is stably formed in geology such as gravel and goose warm stone where the debris is easy to slide and collapse in drilling;

[0034] Subsequent personnel can use a cylindrical steel wire mesh to lower into the anti-collapse casing 200, then pull out the anti-collapse casing 200 from the top, and then drive the photovoltaic pile foundation into the cylindrical steel wire mesh, and then lift the cylindrical steel wire mesh from the top using lifting equipment, and finally fix the photovoltaic pile foundation. The diameter formed by the round drill bit 2 and the four telescopic blocks 4 is directly reduced by contraction after drilling, so that it can be directly moved out from the inside of the anti-collapse casing 200. It is convenient to directly stabilize and prevent the collapse of crushed stone slag before lowering the pile foundation after drilling, facilitate one-time drilling and forming, improve the applicability of drilling holes in different geological conditions, avoid the phenomenon of drilling failure and need to re-drill, and improve the stability of use.
