[0032] Method of use of the present invention:

[0033] In the initial state: the first electric telescopic rod 15 is in a fully extended state, the mounting seat 18 and the drilling shaft 21 are kept in a vertical state by relying on the self-locking of the first motor 19, the second electric telescopic rod 27 is in a state of extension to the limit, the limit slide bar 24 and the sleeve 25 are in the lower limit position, the second spring 45 is always in a compressed state, and the arc-shaped metal plate 43 closes the excavation port 41.

[0034] When collecting soil, the staff pushes the cart 11 to the required position, and then controls the second motor 20 to start through the control panel 13. The second motor 20 drives the drilling shaft 21 to rotate, thereby rotating the hollow drill rod 22. The hollow drill rod 22 drives the sleeve 25 and the spiral blade 26 to rotate through the limit slide bar 24. At this time, the first electric telescopic rod 15 is controlled to retract through the control panel 13, thereby driving the mounting seat 18 to descend through the connecting block 16, and the mounting seat 18 drives the drilling mechanism to descend.

[0035] When the rotating hollow drill rod 22, sleeve 25 and spiral blade 26 pass through the lifting hole 46 and contact the ground, the ground is drilled. After drilling to the required depth, the second electric telescopic rod 27 is controlled to retract through the control console 13, so that the second electric telescopic rod 27 drives the sleeve 25 and the spiral blade 26 to rise. In the process of the sleeve 25 and the spiral blade 26 rising, the loose soil in the drilled hole is brought out, and then soil collection begins. The first electromagnet 39 at the depth position is energized through the control console 13, so that the first electromagnets 39 on both sides repel each other, thereby driving the slide plate 34 to move away from each other, and the slide plate 34 drives the telescopic bottom plate 36, the telescopic vertical plate 37 and the telescopic vertical plate 38 through the connecting rod 35. The scraper 38 is extended, and the telescopic bottom plate 36, the telescopic vertical plate 37 and the scraper 38 rotate with the rotating hollow drill rod 22, thereby coming into contact with the inner wall of the pit and scraping soil from the inner wall of the pit. The scraped soil falls on the telescopic bottom plate 36. As the soil on the telescopic bottom plate 36 accumulates, the soil that has previously fallen on the telescopic bottom plate 36 is squeezed into the hollow drill rod 22 and falls on the fixed plate 31 at the corresponding position for storage; according to the soil at the depth position to be collected, the extension and retraction of the first electric telescopic rod 15 can be controlled to change the height position of the hollow drill rod 22, so that the corresponding controlled collection mechanism at the fixed plate 31 is operated, and the collected soil is stored on the fixed plates 31 at different height positions.

[0036] After the collection is completed, the first electric telescopic rod 15 is extended to the limit position, driving the mounting seat 18 and the drilling mechanism to reset, while the second electric telescopic rod 27 remains in a retracted state, so that the hollow drill rod 22 and the sleeve 25 remain in a staggered state, thereby keeping the excavation port 41 exposed to the outside. At this time, the first motor 19 is controlled by the control console 13 to start and drive the mounting seat 18 to rotate, so that the end of the hollow drill rod 22 is flipped toward the handrail 12 side at a suitable angle, so that the end of the hollow drill rod 22 is tilted downward, so that the opening of the excavation port 41 is tilted downward, and at this time, the second electromagnets 44 at the corresponding positions are energized one by one, and the second electromagnets 44 attract the arc-shaped metal plate 43 into the storage cavity 42, so that the soil stored on the fixed plate 31 at the corresponding position slides out and enters the container prepared in advance by the staff.

[0037] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology in this field to understand the content of the present invention and implement it, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
