[0021] The tree stump removal machine includes a removal mechanism and a drive mechanism. The drive mechanism is installed on the removal mechanism. The removal mechanism is used to remove tree stumps left after tree felling in forestry production, landscaping, and agriculture. The drive mechanism is used to drive the removal mechanism. The removal mechanism can rotate horizontally and vertically. In the vertical position, it can be adjusted up and down by 20 degrees, and in the horizontal position, it can be adjusted from 0 to 50 degrees.

[0022] The clearing mechanism includes a bracket 11, a fixed frame 12, a rotating component 13, a power frame 14, a cutter head 15, and cutter teeth 16. The bracket 11 is mounted on a skid steer loader, which can drive the device to move. The fixed frame 12 is integrally formed on one side of the bracket 11. A bracket is provided on the fixed frame 12 to provide a pivot point for the drive mechanism and the rotating component 13. The rotating component 13 is rotatably connected to the fixed frame 12 and can rotate horizontally. The power frame 14 is hinged to the end of the rotating component 13 and can rotate vertically. The cutter head 15 is rotatably connected to the end of the power frame 14 via a rotating shaft. The cutter teeth 16 are bolted to the outside of the cutter head 15. Damaged cutter teeth 16 can be quickly replaced by removing the bolts. The cutter teeth 16 are symmetrically arranged and have a sharp structure to facilitate the destruction of tree stumps.

[0023] Furthermore, the drive mechanism includes a first hydraulic rod 21, a second hydraulic rod 22, and a hydraulic motor 23. The bottom end of the first hydraulic rod 21 is rotatably connected to the fixed frame 12, and the output shaft end of the first hydraulic rod 21 is rotatably connected to one side of the rotating component 13. The bottom end of the second hydraulic rod 22 is rotatably connected to the top support of the rotating component 13, and the output shaft end of the second hydraulic rod 22 is rotatably connected to the top support of the power frame 14. The hydraulic motor 23 is bolted to the end of the power frame 14, and the output shaft of the hydraulic motor 23 is fixedly connected to the rotating shaft on the cutter head 15. The end of the first hydraulic rod 21 drives the rotating component 13 to rotate, the end of the second hydraulic rod 22 drives the power frame 14 to rotate vertically, and the hydraulic motor 23 drives the cutter head 15 to rotate via the rotating shaft. The rotating cutter head 15 can destroy and remove tree stumps.
