[0007] A further feature of this invention is that a connecting seat is fixedly connected to the outside of the adjusting sleeve, and a breaking tooth is fixedly connected to the outside of the connecting seat by bolts.

[0008] The present invention is further configured such that the drive adjustment assembly includes a threaded rod fixedly connected inside the adjustment sleeve and a motor located at the top of the auger. The interior of the auger is configured as a cavity. The output end of the motor is fixedly connected to a threaded sleeve. One end of the threaded rod extends into the auger and is threadedly connected to the threaded sleeve. The auger is provided with a sliding groove. A slip ring is fixedly connected to the outside of the threaded sleeve and is slidably connected to the sliding groove.

[0009] A further feature of this invention is that a fixed cylinder is fixedly connected to the top of the auger, the motor is fixedly connected inside the fixed cylinder, and a power supply box is also fixedly connected inside the fixed cylinder.

[0010] A further feature of this invention is that at least one sliding hole and one through hole are provided, and the sliding hole and the through hole correspond to each other.

[0012] A further feature of this invention is that a conical head is fixedly connected to the bottom of the adjusting sleeve.

[0013] The beneficial effects of this utility model are as follows: In this utility model, the drilling machine can drive the auger to rotate, thereby drilling holes in the ground. By setting the drive adjustment component, when the auger descends to a certain depth, the drive adjustment sleeve can be moved downward to make the sliding hole correspond to the through hole, so that the groundwater can enter the fixed sleeve through the through hole for storage and sampling. Then, the control adjustment rod can be moved upward to make the sliding hole and the through hole misaligned. Therefore, the drill bit in this utility model is more convenient for drilling and sampling, saving manpower. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-8 The present invention will be further described below.

[0026] To address the problems existing in the background technology, this application proposes the following technical solution: a sampling drill bit for water conservancy engineering survey, including a spiral drill 1, a fixed sleeve 3 fixedly connected to the bottom of the spiral drill 1, an adjusting sleeve 4 slidably sleeved on the outside of the fixed sleeve 3, a through hole 9 inside the fixed sleeve 3, and a sliding hole 7 on one side of the adjusting sleeve 4, with at least one sliding hole 7 and one through hole 9, and the sliding hole 7 and the through hole 9 correspond to each other, so that water can enter the fixed sleeve 3 when the sliding hole 7 and the through hole 9 correspond.

[0027] In this embodiment, a limiting rod 8 is also fixedly connected to the outside of the fixed sleeve 3. The limiting rod 8 is located inside the sliding hole 7. The limiting rod 8 is used to guide the sliding of the adjusting sleeve 4. The limiting rod 8 can also push out the soil stuck in the sliding hole 7 when the adjusting sleeve 4 slides.

[0028] In order to drive the adjustment sleeve 4 to work, a drive adjustment component is also provided on the top of the auger 1.

[0029] Among them, a connecting seat 6 is fixedly connected to the outside of the adjusting sleeve 4, and a breaking tooth 5 is fixedly connected to the outside of the connecting seat 6 by bolts. In order to increase the breaking and drilling effect, the outside of the breaking tooth 5 is toothed, and the breaking tooth 5 is installed obliquely on the outside of the adjusting sleeve 4. A conical head is fixedly connected to the bottom of the adjusting sleeve 4.

[0030] In a further design, the drive adjustment assembly includes a threaded rod 14 fixedly connected inside the adjustment sleeve 4 and a motor 13 located at the top of the auger 1. The interior of the auger 1 is set as a cavity. The output end of the motor 13 is fixedly connected to a threaded sleeve 10. One end of the threaded rod 14 extends into the auger 1 and is threadedly connected to the threaded sleeve 10. The auger 1 is provided with a sliding groove 12. A slip ring 11 is fixedly connected to the outside of the threaded sleeve 10. The slip ring 11 is slidably connected in the sliding groove 12. A fixed cylinder 2 is fixedly connected to the top of the auger 1. The motor 13 is fixedly connected inside the fixed cylinder 2. A power supply box 15 is also fixedly connected inside the fixed cylinder 2. The power supply box 15 is provided with a battery for powering the motor 13. When the threaded sleeve 10 rotates, it drives the threaded rod 14 to work, causing the threaded rod 14 to drive the adjustment sleeve 4 to move upward or downward.

[0031] The above technical solution is explained as follows: Motor 13 drives threaded sleeve 10 to rotate, threaded rod 14 drives adjusting sleeve 4 to move downward, and when sliding hole 7 and through hole 9 move in correspondence, underground water source can enter fixed sleeve 3.

[0032] The usage method of this embodiment is as follows:

[0033] The auger drill 1 is installed on the drilling rig, which drives the auger drill 1 to rotate, allowing it to drill a hole in the ground. Once the appropriate depth is reached, the motor 13 is controlled by a remote control to rotate, which in turn drives the threaded sleeve 10 to rotate. The threaded rod 14 then moves the adjusting sleeve 4 downwards, while the limiting rod 8 guides the adjusting sleeve 4 until the sliding hole 7 aligns with the through hole 9. As the adjusting sleeve 4 slides, the limiting rod 8 can slide within the sliding hole 7. When the sliding hole 7 aligns with the through hole 9, groundwater can enter the fixed sleeve 3 for sampling. Then, the motor 13 drives the threaded sleeve 10 to rotate, causing the adjusting sleeve 4 to move upwards, thus dislocating the sliding hole 7 and the through hole 9. Finally, the auger drill 1 is rotated upwards and removed using the drilling rig.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] Although embodiments of the present invention have been shown and described, the scope of the present invention will be defined by the appended claims and their equivalents for those skilled in the art.
