Embodiment Construction

[0013] like figure 1 As shown in , the blade of the closed ellipsoidal tree shovel is in the opening and closing state before shoveling the tree. The 3 shovels on the left and the 3 shovels (5) on the right are separated into a certain angle, and move toward the tree (1) as a whole with the tree shovel. When the tree shovel travels slowly until trees are surrounded, the tree shovel begins to close and moves downward, and the shovel penetrates the ground (12) and stretches into the depth of the soil while slowly coming together. When the edge is closed, it is closed like cutting watermelon rind, and a complete ellipsoidal root ball is obtained.

[0014] The connection structure (4) of the left and right support frames takes effect after the blade is closed. The support frame (2) is divided into a left front right front movable support frame (supporting the left front blade and the right front blade) and the left and right fixed support frames. On the one hand, the support fr...

Abstract

The invention relates to a closed ellipsoidal tree digging shovel for transplanting trees. The movement of the six shovel blades is controlled by hydraulic pressure. Before excavation work, the three left and three right shovel blades open relative angles to enclose the tree trunk within the working range of the shovel blades. After the upper edges of the six shovel blades are closed, they move downwards from an open and closed shape until the lower edges are closed to form a closed shape. The excavation of the root ball of the tree is completed. Like cutting watermelon rind, the shape of the root ball is ellipsoidal, ensuring Integrity requirements for transplanted roots of trees. After the excavation work is completed, the entire closed shovel surface is controlled by hydraulic pressure to "lift" the trees, and they are transported to a pit of the same size to be transplanted at a certain height and angle, so as to improve the work efficiency and success rate of transplanting with soil.

Description

Technical field [0001] The invention relates to a closed ellipsoid tree digging shovel capable of mechanized tree transplantation. The shovel is controlled by hydraulic pressure, the shovel is inserted into the ground, the shovel is gradually closed, and then the tree is lifted out and removed or planted. right location. Background technique [0002] Transplanting trees can be applied in the following situations: reducing tree loss during construction, road expansion or other construction; a precious tree whose current growing location is limited; quickly establishing a city center garden; selling saplings or adult trees in nurseries, etc. Whether it is evergreen trees with a DBH of 10-15cm or slightly larger, manual excavation and transplanting are still generally used. The efficiency of manual excavation is very low. A small pine tree with a height of about 1.2m and a trunk diameter of about 10cm requires 2 hours of digging work by 2 people. [0003] Tree digging and sho...
