Abstract

<P>PROBLEM TO BE SOLVED: To provide a tool easily excavating ground even if an excavated depth is large. <P>SOLUTION: This manual boring machine comprises a shank and a vertical movement lever 1 and a handle 8 fitted to the upper part thereof. The shank 10 is held by a hand, and the tips A of a shovel are pierced in the ground at an excavated position. Next, the handle is held by a hand and rotated forward and backward and then the vertical movement lever 1 is raised to hold soil by both blade shovels 4 and 5 through pivots 3 to 6 and take out a body from a hole for discharging the soil. By this structure, the manual boring machine can be applied to various businesses (civil engineering works, water works, gas works, electric works, landscape works, field works). <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、柄を１本にして深い穴でも容易に掘削できる道具に関する。 The present invention relates to a tool that can be easily excavated even in a deep hole with a single handle.

従来のポール等などの穴を掘削する道具は図３に示すように、柄１と両刃スコップ２からなり、柄１を両手で持ち両刃スコップ２の先端Ａを掘削したい地面に突刺す。
柄１を水平方向に回し柄１を外側に広げ両刃スコップ２をはさみこんで土を排出する道具である。As shown in FIG. 3, a conventional tool for excavating a hole such as a pole or the like comprises a handle 1 and a double-edged scoop 2. The handle 1 is held with both hands and the tip A of the double-edged scoop 2 is pierced into the ground to be excavated.
It is a tool that rotates the handle 1 horizontally, spreads the handle 1 outward, sandwiches a double-edged scoop 2 and discharges the soil.

しかしながら、以上の従来技術によれば掘削深が深くなるにつれて、柄１が十分に外に開くことが出来ず、両刃スコップ２が閉じることが出来ない為、土を排出する事が困難であった。
そこで、この発明は、掘削深が深くなっても、容易に掘削することが出来る道具を提供することを課題とする。However, according to the above prior art, as the excavation depth becomes deeper, the handle 1 cannot be fully opened outward, and the double-edged scoop 2 cannot be closed, so it is difficult to discharge the soil. .
Then, this invention makes it a subject to provide the tool which can be excavated easily even if excavation depth becomes deep.

以上の課題を解決するために、第１発明は、柄を１本にし、狭い掘削場所でも施工することができることを特徴とする手動穴掘り機である。
また、第２発明は、柄を１本にし、柄の上部に上下レバーを設け上下レバーを動かすことによって両刃スコップが可動することを特徴とする手動穴掘り機である。In order to solve the above problems, the first invention is a manual drilling machine characterized in that a single handle is used and construction can be performed even in a narrow excavation site.
The second invention is a manual drilling machine characterized in that a single handle is provided, a vertical lever is provided at the top of the handle, and the double-edged scoop is moved by moving the vertical lever.

第１発明、第２発明によれば、柄を１本にして柄の上部の上下レバーを動かすことで掘削できるので狭い掘削場所でも施工できる。 According to the 1st invention and the 2nd invention, since it can excavate by moving the up-and-down lever of the upper part of a handle with one handle, it can be constructed even in a narrow excavation place.

以下、本発明の実施形態を図−１・２に基づいて説明する。Hereinafter, embodiments of the present invention will be described with reference to FIGS.

小スペース掘削機の本体はスチール製であり、上下レバー１とハンドル８は滑り防止の為にゴム製のグリップを設けてある。この道具の使い方は、柄の部分８を持ち掘削したい場所にスコップの先端Ａを突刺し、ハンドル８を持ちレバー１前後回転して掘削したい部分と在来土との縁を切って土を排出しやすいようにする。次に上下レバー１を持ち上げ、支点２・３を介し柄１０の内部の連結棒９に力が伝わり支点６が上部に引き上げられ溶接してある両刃スコップ５が閉じ排出したい土をはさむ。土をはさんだ状態で本体を掘削した穴から取出し土を排出する。 The main body of the small space excavator is made of steel, and the upper and lower levers 1 and the handle 8 are provided with rubber grips to prevent slipping. This tool is used to hold the handle 8 and pierce the tip A of the scoop where you want to excavate, hold the handle 8 and rotate the lever 1 back and forth to cut the edge of the part you want to excavate and the soil to discharge the soil. Make it easy to do. Next, the upper and lower levers 1 are lifted, and the force is transmitted to the connecting rod 9 inside the handle 10 through the fulcrums 2 and 3, and the fulcrum 6 is pulled up and welded, and the double-edged scoop 5 is closed and the soil to be discharged is sandwiched. Remove the soil from the hole excavated from the main body with the soil in between.

「実施形態の効果」
この実施形態によれば、柄１０を１本にし上下レバー１を作動することで深い穴でも上部の土が落ちることなく掘れる。したがって、時間と労力を短縮できる。"Effect of the embodiment"
According to this embodiment, it is possible to dig a deep hole without dropping the upper soil by operating the up / down lever 1 with one handle 10. Therefore, time and labor can be shortened.

「他の実施携帯」
図−１・２の実施形態では、柄１０を１本にし上下レバー１を作動して土を排出する構造であったが、他の実施形態では、図−３の柄１部分の途中に支点を設けて、柄を閉じると土をはさむような構造でも良い。"Other mobile phones"
In the embodiment shown in FIGS. 1 and 2, the handle 10 is set to one and the upper and lower levers 1 are operated to discharge the soil. In other embodiments, the fulcrum is located in the middle of the handle 1 portion shown in FIG. It is also possible to use a structure that sandwiches the soil when the handle is closed.
