Description

[0001]
[Field of the Invention]
This invention attaches the thing which attached the blade to the both ends of the iron plate processed into U shape, vertical U shape, and V shape to the arm tip of a mini excavator via an attachment, and removes the root of a plant It is about.
[0002]
[Prior art]
For foliage plants, trees that have grown from 1.2 meters to 2.5 meters in height are excavated. It is densely planted in the field to increase productivity. For this reason, it is difficult to insert similar construction machines such as a mini excavator because the space between trees is so narrow that one person can enter and work, and as a work method, it will be a manual excavation work by hand. The work is dug into a donut shape with a diameter of about 60 cm so that the surroundings can be excavated, and then the root is cut with a dedicated root cutting tool and dug up into a hemispherical shape to have a diameter of 20 to 30 cm.
[0003]
[Problems to be solved by the invention]
As described above, in the densely planted fields, it is difficult to dig up with existing construction machines, and it was forced to perform digging work manually, and the work efficiency and productivity were also poor. Therefore, it was invented in order to answer the demands of the field whether it would be possible to dig up with a simple device at high speed without damaging the surrounding trees in densely planted fields.
[0004]
[Means for Solving the Problems]
The configuration will now be described.
(1) As shown in FIG. 2, the digging device 4 is attached to the attachment 3.
{Circle around (2)} The original bucket attached to the arm 2 of the mini excavator in FIG. 1 is removed and the excavator of the present invention is attached.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
The excavator installed in place of the existing bucket at the tip of the arm of the mini excavator has steel blades on both sides of the iron plate. The A type (U-shaped) and C type (V-shaped) shown in FIG. 2 mainly use potted trees for digging. The B type (vertical U shape) is used when leaving large roots such as root pots. Other digging is done by changing the shape of the digging equipment according to the working conditions. The excavation work can be done by operating the excavation equipment in the same way as using the existing bucket, and the excavation work can reach the purpose of excavation work even in densely planted fields. I can do it.
【The invention's effect】
After digging up, the excavation tool has a width of about 630mm, and the working range is about the width of a fence, so that the roots of the trees are dug up so that the roots of the trees are scooped from the front, and no extra soil is attached to the roots of the excavated trees. Since the root forming work can be omitted, the work process can be shortened and the surrounding trees can be dug in a short time without damaging them.

Claims (2)

One arm of a digging tool formed into a U-shape, vertical U-shape or V-shape, depending on the type of tree, with an attachment attached to the tip of the arm of the mini excavator. In the structure to attach the tip,
The U-shaped or U-shaped or V-shaped arms are open to the ends of both arms;
One arm part in the both arm parts extends longer than the other arm part to constitute an attachment arm part, and its tip is an attachment part to the attachment,
The attachment portion of the attachment arm portion provided at the outer end of the attachment attached to the tip end of the arm of the mini excavator is inclined at the same angle as the tip opened to the tip of the attachment arm portion when the attachment is horizontal. The excavated tree is configured to move away from the outer edge of the attachment,
Tree digging equipment characterized by 2. The tree digging device according to claim 1, wherein the U-shaped, vertical U-shaped or V-shaped digging device has blades on both sides of the iron plate. .
