Description

[Detailed description of the invention] Conventionally, tree roots are cut and trenches are removed mainly using a shovel.

In other words, shove a shovel into the soil to dig up the soil, then cut the roots several times with the shovel, or if the roots are thick, cut the roots with a saw, and in this way remove the soil around the roots of the tree. I use a shovel to dig up the trench and remove the trees.

However, with this method, the process of pushing the shovel into the soil, digging out the soil, and then pushing the shovel into the soil and digging it out again takes time and is tiring due to hard labor.

Sometimes the handle of a shovel stuck in the soil is pushed down like a lever to dig out soil or stones, and the handle bends at the root, and in the case of a wooden handle, the handle bends at the root. It may break.

The present invention is a digging tool that can be fixed to an electric hammer.A steel plate with a blade on the outer edge is attached to the shaft of the electric hammer.The reciprocating movement of the shaft causes the tool to pierce shallowly into the soil several times in succession. The soil around the periphery of the tree was excavated to remove the tree.

The present invention is made by bending a steel plate 1 with a blade on its outer edge, and installing an insertion rod 3 at the end of the main rod 2 in the center, which is inserted into the shaft 8 of an electric hammer and fixed. This invention relates to a tree root cutting and digging tool that is attached to an electric hammer.

4 is a pin, 5 is a pin insertion hole, 6 is a cotter pin, and 7 is an electric hammer.

When the insertion rod 3 at the tip of the central main rod 2 of the root cutting and digging tool of the present invention is fitted into the hole of the reciprocating shaft 8 of the electric hammer 7 and fixed, the electric hammer is activated and the soil is dug with a shovel. Unlike , the number of times of driving is large, so it gradually goes deeper into the soil without digging up the soil, and the depth of one driving is not as deep as the one on the left, and the steel plate 1 that is the digging tool is a complex. Deep cuts are formed on the left and right sides of the upper part, so that there is little resistance when tilting the steel plate 1 back and forth while moving it up and down. Alternatively, since it is possible to dig inward or outward, the soil around the roots of the tree can be dug into a rounded shape suitable for tying ropes, making it easy to dig up the tree. I can do it.

Furthermore, even thick roots can be cut many times with the blade on the outer edge of the steel plate 1, so the roots can be cut without using a saw unlike when digging up with a conventional shovel.

Also, since the stone in the soil can be broken by this blade, the digging speed is fast.

In this way, if the root cutting and digging tool of the present invention is attached to an electric hammer, tree digging work can be done extremely efficiently.
