Technical Field

[0001] The utility model belongs to the technical field of tree planting, and particularly relates to a tree planting pit-digging device. Background Technique

[0002] Afforestation is a production activity of planting new forests or regenerating forests, and it is a basic link in cultivating forests. If the planting area is large and a forest and forest environment can be formed in the future, it is called afforestation. If the area is very small and a forest and forest environment cannot be formed in the future, it is called tree planting. When carrying out tree planting, it is first necessary to carry out pit-digging operations, and it is becoming more and more common to use machinery to dig tree pits.

[0003] The pit-digging devices used in tree planting are mature in technology and widely used, which can effectively improve the efficiency and standard of planting and pit-digging. However, the handles of the pit-digging devices are mostly fixed structures, so that the lifting heights of the arms of operators with different heights are different when holding the pit-digging devices, making it slightly uncomfortable for taller or shorter personnel to operate. Therefore, a tree planting pit-digging device is needed that can adjust the height of the handle of the pit-digging device so that the height of the handle adapts to the body structure requirements of personnel with different heights, thereby improving the adaptability between the pit-digging device and different operators.
