Description

[Detailed description of the invention] The present invention is a hole digger for the purpose of shaping a hole for transplanting a seedling, and is particularly suitable for shaping a hole for planting a seedling in the case of afforestation. be.

When transplanting seedlings for reforestation in mountainous areas, the roots of weeds and shrubs were infested, so they were cut open with a hoe and the soil was dug up before being transplanted.

Particularly in the densely grown ground of bamboo grass, which is common in mountainous areas, the roots are so hard that even a hoe blade cannot hold them, making it inefficient and labor-intensive. It was left unattended.

In addition, even if you cut the roots and dig up the soil without much effort and plant the seedlings, the cut roots and bamboo leaves will get mixed into the planting soil, and these contaminants, which rot slowly, will hinder the compatibility of the roots of the seedlings with the soil. To make matters worse, many of the seedlings withered due to the formation of hollow areas.

The present invention does not have the above-mentioned drawbacks, and allows seedlings to be planted using one's body weight with relatively little effort and without digging up the soil. A sharp blade is formed on the edge to shred soil and roots by the rotation of the sword part, and a legrest is provided with a reinforcing material to uniformly load the sword part and reinforce the handle. This will be explained in detail with reference to the embodiment of the hole digging device of the present invention shown in FIG.

1, 1' is a sword part made of metal whose lower part is narrower than the upper part and whose upper part is approximately semicircular (or dogleg-shaped); The edges are shaped like sharp tip blades 7, 7' and side blades 8, 8'.

The two sword parts 1, 1' are substantially cylindrical in shape with their inner surfaces facing each other, and their upper ends are rotatably connected to each other by shafts 2, 2'.

A handle 3, 3' is attached to the upper center of the two sword parts 1, 1', and a grip 1) 4.4' is attached to the tip of the handle 3, 3'.

The upper central part of the upper sword parts 1, 1' is formed with footrests 5, 5' that protrude in the horizontal direction, followed by handles 3, 3'.
<6.6' is a reinforcing member that forms a nearly right triangle with the footrests 5 and 5'.

Next, to explain how to use this invented tree planter, there are 4 grips,
Holding the 4' or handle 3, 3' parts, overlap the tips of the sword parts 1, 1', and drive the matched tip blade parts 7, 7' into the planting position of the seedling firmly with one sharp point. Since the sharp end blades 7 and 7' with matching tips are driven in, it is relatively easy and deep to drive in, and even if there are bamboo roots, etc., they can be cut off or driven into places where there are no roots. It is also easy.

After driving in like this, grab the handles 4 and 4' and press the sword part 1,
1' by shaking it back and forth, left and right, or in the direction of rotation.
, 1' plunge into the ground a little deeper, and when the appropriate amount of penetration is obtained, put your feet on the footrests 5, 5' and put your weight on them, and bring the grips 4, 4' closer together, then the shaft 2 ,2
The tips of the sword parts 1, 1' are rotated about the point 1' in the direction of opening.

Then, the side blade parts 8, 8' of the sword parts 1, 1' work to slightly scrape the inner circumferential surface of the hole, making it possible to easily open the sword parts 1, 1', as well as deepening the hole and deepening the bottom. It was scraped away and soft soil was laid down.

Next, insert the seedling from the root side through the almost circular cylindrical part on the upper surface of the sword parts 1, 1', and turn the sword parts 1, 1' left and right with the grips 4, 4' as if rotating. By pulling out the seedling while rotating, the soil around the hole is shaved into thin pieces, filling the roots of the seedling. After pulling out the blade parts 1 and 1', the soil around the seedling is compacted to ensure complete transplantation. And it's easy to do.

In this way, the present invention is based on the structure of the soil.
In the bamboo grass, the roots of the bamboo grass are rampant, and the tip of the blade easily cuts them and penetrates into the hole.As the hole is dug deeper, the side blade divides the soil and roots around the hole into smaller pieces, and the roots become like sticks. Since they are not cut long, they do not mix and sprout, and they are planted in their transplanted soil layer, so transplanting is easy and very natural, and they take root well.

In this way, the present invention not only increases the mechanical strength of the handle, but also makes it possible to transplant seedlings by cutting circularly into the soil and dividing the soil and roots into small pieces with the blade, rather than digging up the soil. Since the hole is shaped, it is possible to transplant the seedling in an extremely natural manner without changing the soil layer.
It is possible to plant trees even on land that is traditionally left unattended due to dense bamboo grass, and it is highly practical because it uses the whole body weight rather than the labor of the hands and feet, so there is no local fatigue.

[Brief explanation of the drawing]

The figures show an embodiment of the hole digging device of the present invention, in which Fig. 1 is a partially cutaway front view, Fig. 2 is a side view, and Fig. 3 is a plan view. Code: 1, 1' is the sword part, 2, 2' is the shaft, 3, 3' is the handle,
5 and 5' are footrests, 6 and 6' are reinforcing materials, 7 and 7' are tip blades, and 8 and 8' are side blades.

Claims (1)

[Scope of utility model registration request] A hole digging tool has a sword part shaped like a bird's beak and a handle connected to it.The sword part has a half-moon shape at the top and a flat bottom, with side blades on both sides and the bottom edge. The upper part is cylindrical, the lower edges overlap each other, and the upper part is pivoted with a shaft, and the lower part can be opened and closed. A tree planter made of bamboo fabric that has a handle on each part and a footrest that also serves as reinforcement between this and the sword part.
