Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 4 As shown, the utility model provides a rotary drilling rig drill bit that is easy to clean, including an auger rod 1, a support 2, a carrier 3 and a rotation drive assembly 6. The upper end of the carrier 3 is fixedly connected to a top block 4, and the top block 4 is rotatably connected to the support 2 through a rotating shaft 401. The auger rod 1 is located below the carrier 3, and the rotation drive assembly 6 is arranged between the auger rod 1 and the carrier 3. A telescopic cylinder 5 is fixedly installed inside the support 2, and the telescopic end of the telescopic cylinder 5 is fixedly installed with an inverted U-shaped seat 7 through a transmission block 501. The telescopic cylinder 5 can be used to drive the inverted U-shaped seat 7 to move laterally. The outer portion of the rotating shaft 401 is fixedly sleeved with a gear ring 402, and the bottom of the inverted U-shaped seat 7 is symmetrically fixedly connected with two transverse racks 8, which are meshed with the gear ring 402. When the transverse racks 8 move laterally with the inverted U-shaped seat 7, the auger rod 1 can be driven to flip, so that the auger rod 1 can be flipped from a vertical state to a horizontal state.

[0022] Among them, such as Figure 1 As shown, the rotary drive assembly 6 includes a motor 601 and a drive disk 602. The motor 601 is fixedly mounted on the bottom of the carrier 3, and the drive disk 602 is fixedly connected to the output shaft of the motor 601. The auger rod 1 is fixedly mounted on the bottom of the drive disk 602 through the positioning disk 101, so that the motor 601 in the rotary drive assembly 6 can drive the auger rod 1 to rotate.

[0023] Among them, such as Figure 2 and Figure 4As shown, a guide groove 201 is defined on the inner side of the support 2, and a limiting slide 502 is fixedly mounted on the transmission block 501 and slidably connected to the guide groove 201. There are two limiting slides 502, which are symmetrically arranged. This ensures that the limiting slides 502 cooperate with the guide groove 201 to provide a good guiding effect, thereby ensuring stability during lateral movement of the transmission block 501 and the inverted U-shaped seat 7.

[0024] Among them, such as Figure 4 As shown, reinforcement seats 9 are fixedly connected on both sides between the carrier 3 and the top block 4. The cross-section of the reinforcement seats 9 is triangular, which achieves the purpose of improving the strength of the connection structure between the carrier 3 and the top block 4.

[0025] Among them, such as Figure 3 As shown, the upper end of the support 2 is fixedly connected to a connecting frame 202, and mounting holes 203 are provided at each end corner of the surface of the connecting frame 202. The support 2 can be mounted on the telescopic arm of the rotary drilling rig through the connecting frame 202 and fasteners.

[0026] The working principle of this utility model:

[0027] When using the rotary drilling rig drill bit, the auger rod 1 is in a vertical state, the telescopic arm of the rotary drilling rig drives the support 2 and the auger rod 1 to rise and fall, and the motor 601 in the rotary drive assembly 6 drives the auger rod 1 to rotate, so as to realize the rotary drilling operation. After the rotary drilling operation is completed, if it is necessary to clean the soil attached to the auger rod 1, the telescopic cylinder 5 is used to drive the inverted U-shaped seat 7 to move horizontally to one side, and the horizontal rack 8 at the bottom of the inverted U-shaped seat 7 cooperates with the gear ring 402 to drive the auger rod 1 to flip upward until the auger rod 1 is flipped from the vertical state. The screw drill rod 1 is rotated and adjusted to a horizontal state, and the motor 601 in the rotary drive assembly 6 is used to drive the screw drill rod 1 to rotate. The soil's own gravity can be used to cause it to quickly detach and fall off the screw drill rod 1, so as to facilitate the complete removal of the soil attached to the screw drill rod 1. After the cleaning is completed, the motor 601 is turned off, and the telescopic cylinder 5 is used to drive the inverted U-shaped seat 7 to move horizontally to the other side for reset. The horizontal rack 8 at the bottom of the inverted U-shaped seat 7 cooperates with the gear ring 402 to drive the screw drill rod 1 to flip downward until the screw drill rod 1 is flipped from the vertical state to the horizontal state.
