Finally, the control on the lifting plate 120 is released, the drilling machine drives the drill rod 410 to freely rotate, the lifting plate 120 has a downward movement trend under the action of the elastic force of the third elastic piece 133, and when the drill rod 410 drives the spiral blade fan 420 to rotate, the soil scraping part 312 also moves downward along with the lines of the spiral blade fan 420, and at the moment, the lifting plate 120 drives the soil scraping structure 300 to move downward.
During the downward movement of the lifter plate 120, the cooperating resilient control assembly 130 is continually replaced to ensure that the pressure between the scraping portion 312 and the helical blade 420 remains within a predetermined range.
The above is only a preferred embodiment of the present application, and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
