[0002] Tree transplanters are widely used in fields such as landscaping to transplant mature trees from one place to another. One of the core operations is to dig the soil around the tree roots. The digging blades of traditional tree transplanters have some problems during use:

[0003] The inclination angle of the digging blade of a traditional tree transplanter is usually fixed, which cannot adapt to the needs of trees of different sizes, resulting in an inappropriate digging blade angle and uncontrollable amount of excavated soil, affecting the survival rate of the trees. The inclination angle of the digging blade is not flexible to adjust, and complex operations are required to ensure the appropriate amount of soil excavation, which is difficult to meet the flexible requirements for the amount of excavation in actual work. The fixed-angle digging blade can easily damage the roots of trees, increasing the uncertainty of tree growth after transplantation. Utility Model Content
