3. The drill rod changing apparatus of claim 1 wherein the diameter of the pass through bore is smaller than the outer diameter of the drill rod and larger than the outer diameter of the clamping assembly.

4. The drill rod changing device according to claim 1, wherein the diameter of the threaded connecting section of the drill rod end is larger than the diameter of the drill rod middle; a limit hole is formed in the threaded connection section of the drill rod; an anti-rotation component is arranged in the outer sleeve; when the lifting clamping head is contracted, the anti-rotation assembly can be inserted into the limiting hole.

5. The drill rod changing device according to claim 4, wherein the inner sleeve rod is a plurality of and annularly distributed; a guide block is arranged in the outer sleeve; the inner sleeve rod can linearly move along the guide block; the outer sleeve is provided with a mounting hole opposite to the limit hole; the anti-rotation component is a spring pin; the spring pin is horizontally arranged in the mounting hole, and the end part, which is close to the connecting arm, is an inclined block; the end part of the inner sleeve rod, which is away from the cover box, is provided with a ball; when the inner sleeve rod moves towards the outer sleeve, the ball presses the inclined block, so that one end of the spring pin is clamped into the limiting hole.

6. A drill rod changing device according to any one of claims 1-5, wherein a pressure sensor is arranged on the contact surface of the limiting component and the drill rod; the power head is provided with a position sensor which is opposite to the second target position; the control system receives signals of the pressure sensor and the position sensor and drives the selecting mechanism, the power head and the shifting mechanism to act; the control system comprises an operation panel, wherein a digital button is arranged on the operation panel; the sequence of the plurality of limit components corresponds to the number numbers of the number buttons one by one; one of the digital buttons is pressed, and the limiting component corresponding to the digital button is moved to a first target position.

7. A drill rod changing method, characterized in that based on the drill rod changing device of claim 5, the rod changing method comprises the following steps:

automatic lever disassembly:

s1: when the rod replacing operation is needed, the power head drives the used drill rod to ascend and separate from the drill rod connected with the power head and positioned in the ground; when the power head drives the used drill rod to ascend to the top of the support frame, the clamping assembly moves to a second target position under the action of the second linear driving assembly;

s2: the lifting driving action drives the outer sleeve to deviate from the inner sleeve rod, and the spring pin returns to the outer sleeve; the power head drives the used drill rod to descend until the used drill rod is sleeved on the outer side of the outer sleeve; the lifting driving action drives the outer sleeve to approach the inner sleeve rod, and the spring pin is clamped into the limiting hole; the power head rotates under the action of self power, so that the power head is separated from the used drill rod;

s3: in the process that the power head is separated from the used drill rod, the operation panel is manually operated, so that an empty limiting assembly moves to a first target position;

s4, the second linear driving assembly acts to drive the used drill rod to move to the second storage groove, and the lifting driving is away from the inner sleeve rod in the moving process, so that the spring pin returns; the second linear driving assembly continuously acts until the used drill rod reaches the first storage groove and contacts with the limiting assembly;

automatic pole loading:

d1: manually operating the operation panel, so that a required limit component moves to a first target position;

d2: the lifting driving action drives the outer sleeve to deviate from the inner sleeve rod, and the outer sleeve is clamped into the drill rod to be replaced; the second linear driving assembly drives the drill rod to be replaced to move along the second storage groove;

d3: when the drill rod to be replaced reaches a second target position, the outer sleeve is driven by lifting driving action to be close to the inner sleeve rod, and the spring pin is clamped into the limiting hole; the power head descends and is connected with the drill rod to be replaced under the rotation action of the power head;

d4: the outer sleeve is far away from the inner sleeve rod, at the moment, the spring pin is far away from the limiting hole, the power head moves upwards, and the clamping assembly moves to a first target position to be standby.
