[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0017] Please see Figure 1 and Figure 2 This embodiment introduces a tree-planting hole-drilling cutter head, used in desert afforestation operations for drilling holes and inserting seedlings. The tree-planting hole-drilling cutter head includes a cutter holder 11, a rotating drum 8, and a motor 7.

[0018] The rotating drum 8 is rotatably mounted on the tool holder 11; the outer peripheral wall of the rotating drum 8 is provided with a spiral chip-removing blade 3; the lower end of the rotating drum 8 is provided with a rotatable cutter head 1; the rotating drum 8 is a hollow structure that runs through the top and bottom, and the cutter head 1 can be rotated to close or open the lower end opening of the rotating drum 8; the motor 7 is mounted on the tool holder 1 and is connected to the rotating drum 8 for transmission, and the motor 7 is used to drive the rotating drum 8 to rotate.

[0019] In the above scheme, when the rotating drum 8 rotates, the cutter head 1 is in an inward state due to the resistance of the sand, drilling holes in the sand. At the same time, the sand particles are discharged upward by the spiral structure of the chip-removing blade 3. After drilling is completed, the cutter head 1 is unfolded, and the seedling is put into the rotating drum 8 through which the upper and lower parts are connected. Since the cutter head 1 closes or opens the lower opening of the rotating drum 8 by rotating, the operator can retract the cutter head 1 when drilling holes as needed, and unfold the cutter head 1 when putting seedlings in so that the seedlings can fall from the bottom of the rotating drum 8 into the drilled holes. This utility model can put seedlings in without pulling out the cutter head 1, which is effective.

[0020] In this embodiment, please refer to Figure 1 and Figure 2 Multiple cutter heads 1 are provided and are evenly spaced circumferentially. Multiple cutter head shafts 2 corresponding to the multiple cutter heads 1 and passing through the chip removal blades 3 are provided on the outside of the rotating drum 8. One end of the cutter head shaft 2 is connected to the corresponding cutter head 1. The other end of the cutter head shaft 2 is connected to a lever 14. A dial 4 is provided on the rotating drum 8. An upwardly extending lever 15 is fixed on the lever 14. The lever 15, the lever 14 and the cutter head shaft 2 form a Z-shaped structure. A guide groove is provided on the dial 4 to accommodate the lever 15. When the lever 15 is located at one end of the guide groove, the cutter head 1 is in a preset fully retracted state to close the lower opening of the rotating drum 8. When the lever 15 is located at the other end of the guide groove, the cutter head 1 is in a preset extended state and the lower opening of the rotating drum 8 is opened. The two ends of the guide groove are used to limit the lever 15. When the rotating barrel 8 rotates to make a hole, the cutter head 1 is resisted by the sand and soil and retracts inward. At this time, the lever 15 is located at the outward end of the guide groove. After the hole is made, the lever 15 is pushed inward to make the cutter head 1 unfold outward, so that the lower opening of the rotating barrel 8 can be opened, allowing the seedling to fall from the lower end of the rotating barrel 8.

[0021] Further, please refer to Figure 1 In this embodiment, both the cutter head 1 and the cutter head shaft 2 are provided in threes.

[0022] Specifically, please refer to Figure 3 The output end of the motor 7 is equipped with a drive sprocket 5; the upper end of the rotating drum 8 is equipped with a driven sprocket 12; the drive sprocket 5 is connected to the driven sprocket 12 through a chain 6, and the drive sprocket 5 can drive the transmission sprocket 12 and the rotating drum 8 to rotate through the chain 6.

[0023] Please see Figure 1 and Figure 2 To facilitate the operator in adjusting the angle of the cutter head 1, two fixing rings 13 are spaced apart along the axial direction on the rotating drum 8; the chip removal blade 3 is positioned between the two fixing rings 13; each fixing ring 13 is provided with a shaft hole through which the cutter head shaft 2 passes.

[0024] Please see Figure 1It should be added that the inner edge of the chip removal blade 3 is provided with a receiving groove, and the receiving groove and the outer wall of the rotating drum 8 form a through hole for the blade shaft 2 to pass through.

[0025] To ensure more stable rotation of the rotating drum 8 and safer overall operation, an extension sleeve 9 is installed at the bottom of the tool holder 11, coaxially with the rotating drum 8. The rotating drum 8 rotates through the extension sleeve 9 and extends downward. Reinforcing plates 10 are evenly distributed circumferentially on the outer wall of the extension sleeve 9 to connect the extension sleeve 9 and the tool holder 11, thereby strengthening the structural strength of the extension sleeve 9 and the tool holder 11. Example

[0026] This embodiment provides a tree planting hole drilling head, which differs from Embodiment 1 in that a drive pulley is installed at the output end of the motor 7, a driven pulley is installed at the upper end of the rotating drum 8, and the drive pulley and the driven pulley are connected by belt drive.
