When digging a hole for planting trees in a forest, the device is moved to a suitable position. After the movement is completed, the adjusting mechanism is started, and the adjusting mechanism drives the drilling mechanism to move downward, so that the drilling mechanism contacts the ground. During this period, the drilling mechanism is started and the drilling mechanism drills the ground. When the adjusting mechanism drives the drilling mechanism to move downward, the support shaft drives the first top block to rotate through the cooperation between the two pulleys and the belt.

During this period, the protrusion will rotate with the center of the rotating shaft as the center of the circle, and the push rod will push the piston plate to slide back and forth inside the intake pipe under the action of the protrusion and the shaft sleeve. The piston plate will compress the air pressure inside the intake pipe when sliding, and the compression The gas will be transported to the inside of the annular tube. At this time, the water flow inside the annular tube will be sprayed out through the water spray pipe under the action of air pressure. Since one end of the water spray pipe is tilted toward one side of the drilling assembly, the sprayed water will fall on the soil where the pit is dug, so as to humidify the soil, thereby improving the equipment's digging efficiency for the soil and preventing the equipment's digging efficiency from being reduced due to the hard soil geology. At the same time, the soil can be softened by spraying water, thereby preventing the drilling assembly from being subjected to greater resistance due to the hard soil, thereby causing wear to the drilling assembly.

The piston plate 48 compresses the air pressure inside the intake pipe 49 when sliding, and the compressed gas will The water is transported to the inside of the annular tube 38. At this time, the water flow inside the annular tube 38 will be sprayed out through the water spray pipe 50 under the action of air pressure. Since one end of the water spray pipe 50 is tilted toward one side of the drilling assembly 21, the sprayed water will fall on the soil where the pit is dug, so as to humidify the soil, thereby improving the equipment's digging efficiency of the soil and preventing the equipment's digging efficiency from being reduced due to the hard soil geology. At the same time, the soil can be softened by spraying water, thereby preventing the drilling assembly 21 from being subjected to greater resistance due to the hard soil, thereby causing wear to the drilling assembly 21.
