Abstract

<P>PROBLEM TO BE SOLVED: To solve problems in a conventional boring machine wherein, though a hole is excavated by opening/closing two shanks of the machine when a pole is buried in the ground, the shanks cannot be sufficiently opened as an excavated depth becomes larger, upper soil must be removed to a position where the shanks can be opened, and extra time and labor are consumed. <P>SOLUTION: This boring machine comprises one shank, and a vertical lever 1 and a handle on the upper part of the shank. The shank 12 is held, and the tip A of a shovel is pierced in a place to be excavated. Next, the handle 7 is held and horizontally rotated, and then the vertical lever 1 is pushed down to hold the soil by a double blade shovel 4 through pivots 2 to 6 and a body is taken out from the hole to discharge the soil. Since the handle 7 can be removed and fitted into a remount nut 8, the excavation can be performed also in a restricted excavating place. By this, the manual boring machine can cope with various types of businesses (water-supply works, gas fitting work, electric works, landscaping works, agricultural works). <P>COPYRIGHT: (C)2005,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.

従来のボール等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 ball or the like is composed of 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-mentioned 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, an upper / lower lever is provided on the upper portion of the handle, and the double-edged scoop is moved by moving the upper / lower 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７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１２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７を持ち水平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を押し下げ、支点２・３を介し柄１２の内部の連結棒１３に力が伝わり支点５が上部に引き上げられ支点６と溶接してある両刃スコップ４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。両刃スコップ４上部についてある開口補助バネ９は上下レバー１を押し上げることなく自動的に両刃スコップ４が開くように施してある。両刃スコップ４の交わるセンターボルト１１だけでは、回転力に耐えられるだけの強度がないのでねじれ防止補強材１０を設けた。また、柄１２の上部に付いているはめ替えナット８の部分は狭い掘削場所でも施工できるように、ハンドル７のネジを緩めてはめ替えナット８に取り付け出来るようにしてある。 The main body of the small space excavator is made of steel, and the upper and lower levers 1 and the handle 7 are provided with rubber grips to prevent slipping. To use this tool, hold the handle 12, pierce the tip A of the scoop at the place you want to excavate, hold the handle 7 and rotate it horizontally to cut the edge between the part you want to excavate and the conventional soil so that you can easily drain the soil. To. Next, the upper and lower levers 1 are pushed down, the force is transmitted to the connecting rod 13 inside the handle 12 through the fulcrums 2 and 3, the fulcrum 5 is pulled up, the double-edged scoop 4 welded to the fulcrum 6 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. The opening auxiliary spring 9 at the upper part of the double-edged scoop 4 is provided so that the double-edged scoop 4 is automatically opened without pushing up the vertical lever 1. Since only the center bolt 11 where the double-edged scoop 4 intersects is not strong enough to withstand the rotational force, the anti-twisting reinforcing material 10 is provided. Further, the part of the fitting nut 8 attached to the upper part of the handle 12 can be attached to the fitting nut 8 by loosening the screw of the handle 7 so that it can be constructed even in a narrow excavation place.

Effects of the embodiment

この実施形態によれば、柄１２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。 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 12. Therefore, time and labor can be shortened.

Other implementation mobile

図−１・２の実施形態では、柄１２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、柄を閉じると土がはさむような構造でも良い。 In the embodiment shown in FIGS. 1 and 2, the handle 12 is used as 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 have a structure in which soil is sandwiched when the handle is closed.
