Description

Technical Field

[0001] The utility model relates to the technical field of seedling planting, in particular to a hole digger for seedling planting. Background Technique

[0002] In existing greening projects, finished trees or semi-finished trees are usually planted to obtain obvious greening effects in a short period of time and achieve the purpose of quickly increasing the greening area. However, due to the usually large volume of finished trees, in order to ensure their transplant survival rate, native soil is usually reserved at the tree roots to ensure that some roots are not damaged during transplantation and improve the survival rate of the trees. However, the retention of native soil will obviously increase the amount of soil excavation during transplantation, thus increasing the input of transplantation work and time during the transplantation process.

[0003] After retrieval, a hole digger for seedling planting disclosed in the Chinese patent publication No. CN106376276A has the following technical key points: it includes a vehicle body, wheels, a hole digging device, and a hydraulic system for controlling the hole digging device. The hole digging device includes a first arm, a second arm hinged to the first arm, and a telescopic arm telescopically installed in the second arm; one end of the telescopic arm extending out of the second arm is connected with a digging cylinder, and the digging cylinder is in transmission connection with a driving motor arranged in the second arm through a driving shaft penetrating through the telescopic arm and the second arm.

For this reason, we propose a hole digger for seedling planting to solve the above problems. Utility Model Content
