Technical Field

The invention belongs to the field of forestry and landscaping machinery, and relates to a tree mover capable of enabling a tree root to be provided with soil balls when trees are transplanted.

Background

The existing tree mover has three types, namely, a semicircular arc rotary cutter tree mover which is expensive and difficult to accept by most practitioners; secondly, the petal type hydraulic shovel tree mover and the vehicle-mounted chain rotary tree mover are large and heavy in size, most of actual tree digging situations are to select and dig in a nursery forest, and thus a huge machine cannot be flexibly connected in series in the nursery and is not practical; and thirdly, the pneumatic pick electric shovel type portable handheld tree mover is actually only used for rubbing a very thin seam at the periphery of a tree by shoveling one by one under the ground, so that time and labor are wasted, and the survival rate is low because the conical shape of the earth ball damages the root too much. No matter be semicircle rotary cutter tree mover, still petal hydraulic shovel tree mover all need change the cutter when digging the trees of equidimension earth ball not, and the tool changing needs to spend a lot of time moreover. Based on the above situation, no general practical tree mover can be popularized so far.
