When it slides to a suitable position, the tightening knob 31 is screwed to tighten it on the scale plate 29, and then the second driving motor 21 is started to drive the threaded rod 19 to rotate, thereby driving the sliding block 22 to move back and forth on the first sealing plate 5. Under the action of the guide rod 36, the sliding block 22 can be made more stable during lifting. At the same time, the third driving motor 25 is started during the lifting process to drive the threaded drill rod 26 to rotate and pass through the opening 7 to drill holes in the ground. When the sliding block 22 abuts against the top of the circular frame 30, it can be limited to accurately adjust the digging depth of the threaded drill rod 26, so that planting holes of different depths can be dug according to needs, thereby improving the applicability of the device.

[0034] At the same time, when rotary drilling is performed, the water pump 11 is started, and the suction force generated by the water pump 11 is used to transport water along the connecting pipe to the water spray pipe 23, and then sprayed out through the nozzle 24 to prevent dust generated during drilling from flying around and causing damage to the physical and mental health of the workers, and to cool the drill rod. At the same time, after the drilling is completed, the surface of the threaded drill rod 26 can be cleaned, avoiding the need for cleaning again later, saving time and effort.
