Abstract

<P>PROBLEM TO BE SOLVED: To provide a shovel of which the angle of a handle and a scoop can be freely changed to be adaptable for various works. <P>SOLUTION: A pull 2 is formed at the upper part of the handle 1 and an angle changing structure 3 is formed at the lower end. By attaching a scoop fitting plate 4 rotating integrally with the structure, an angle between the handle and the scoop can be freely changed between the position A and the position B. When the angle returns to an original position, it can be returned by drawing the pull 2. The scoops 5 with various shapes can be used depending on works. <P>COPYRIGHT: (C)2004,JPO

Description

【0001】
【発明の属する技術分野】本発明はスコップ・シャベルに関するものである。
【0002】
【従来の技術】スコップとしては柄の先端にサジ形のすくい部を取り付けた先端部の角度変更不能の物と、特開2000−192494(P2000−192494A)のように角度変更機構が土砂に直接せつする構造の物がある。
【特許文献1】
特開2000−192494
【0003】
【発明が解決しょうとする課題】上記従来のスコップは次のような課題がある。
1.角度変更機構に土砂等が挟まる事や、周囲の土砂がワイヤに当たり操作出来ない事がある。
2.柄とすくい部の角度を変更するのにハンドルを使用しているため、相当大きな力で引くことが必要である。
3.角度を固定する時にハンドルとレバーを同時に動かす必要があり、柄を支えることが不安定になる。
4.すくい部の取替えができず一定の形状の穴にしか使用できない。
【0004】
【課題を解決するための手段】上記課題を解決するために、本発明は下記のスコップを提供するものである。
1.角度変更機構を側板により密閉することにより課題1を解決する。
2.柄を動かすことで柄とすくい部の角度を変更するので大きな力を必要とせず課題2を解決する。
3.角度固定にバネの反発力利用で自動的に固定するので課題3を解決する。
4.すくい部取り付け板を設け、すくい部を作業に合せて替える事で課題4を解決する。
【0005】
【作用】本発明のスコップは下記各項の作用を及ぼす。
1.従来のスコップで深い縦穴を掘る場合土砂を掘り砕くことはできても、砕いた土砂をすくい部の上に乗せすくい上げるためには、穴の上部を必要以上に広く掘ることが必要であつたが、本発明のスコップは柄を前後に動かすことにより柄とすくい分の角度を変え、土砂をすくい部の上に乗せてすくい上げるので穴の上部を必要以上に広く掘る必要はない。
2・竪穴横穴をとはず、ヒュム管のような小さな穴の内に蓄積した土砂の除去に関しても、角度変更機構内の歯車の歯数を変えることにより、柄とすくい部の角度を数回変える事で内部の土砂を除去することができる。
3・柄とすくい部の角度を所定の位置で固定することにより、くわ等として使用でき更に、すくい部を作業に合わせて替えることにより農業、土木、家庭用品として多目的に使用できる。
【0006】
【発明の実施の形態】
(1)次に、本発明の実施形態を図2に従い説明する。
第一の位置で5すくい部を土砂に突き入れ1 柄の部分を前に押すと、5すくい部は土砂により固定されており3e歯車の中心にある3f歯車軸を中心として柄は第二の位置に回転する。この時3d歯車固定弁は上部にある3cバネが縮むことにより、3e歯車の歯表面を滑り前の歯に移動する。この時点で3d歯車固定弁は3c バネの反発力により歯車にくい込み、柄を第三の位置に引くと、歯車固定弁の3d−1後部と3e−1歯車前面が歯車軸に垂直なため歯車面を滑る事ができず、3f歯車軸を中心として1柄の回転と同様に3e歯車が回転しその結果、 3e歯車と一体で動く4すくい部固定板を通して、5すくい部を第四の位置に移動させる。この動作を繰り返すことにより、5すくい部と1柄の角度を思うところに変えることができる。土砂を除去した後5すくい部と1柄の角度を元に戻すには、 1柄の上部にある、2a引き手を引くことで、2b ワイヤにより引かれた長さだけ3cバネが縮み3d歯車固定弁は上に上がり3e歯車から切り離される、5すくい部と1柄の角度が思うところにきた時、2a引き手を放すと3d歯車固定弁は3cバネの反発力により3e歯車にくい込み歯車の回転を固定する。
(2)次に添付図面4に従い説明する。
角度変更機構内に土砂の進入を防止しるため3a角度変更機構側板と3h軸受の間に3j硬質ゴムパッキンを使用し土砂がはさまることを防止した。
【0007】
【発明の効果】
角度変更機構を側板により密閉することにより土砂の進入を防ぎ、柄を前後に動かすことで柄とすくい部の角度を変更することができ、角度固定にバネの反発力利用で自動的に固定することにより操作性を高め作業の効率化ができた。
すくい部取り付け板を設け、すくい部を作業に合せて替える事で多種類の作業に使用されるようになつた。

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scoop shovel.
[0002]
2. Description of the Related Art As a scoop, the angle of the tip cannot be changed by attaching a serpentine rake to the tip of a handle, and the angle changing mechanism is directly applied to earth and sand as disclosed in JP-A-2000-192494 (P2000-192494A). There is an object of the structure to be set.
[Patent Document 1]
JP 2000-192494
[0003]
The conventional scoop has the following problems.
1. There is a case where earth and sand are caught in the angle changing mechanism, and there is a case where surrounding earth and sand hit the wire and cannot be operated.
2. Since the handle is used to change the angle between the handle and the rake, it is necessary to pull with considerable force.
3. When fixing the angle, it is necessary to move the handle and lever at the same time, and it becomes unstable to support the handle.
4. The rake cannot be replaced and can only be used for holes of a certain shape.
[0004]
In order to solve the above problems, the present invention provides the following scoops.
1. Problem 1 is solved by sealing the angle changing mechanism with a side plate.
2. By moving the handle, the angle between the handle and the rake portion is changed, so that the problem 2 is solved without requiring a large force.
3. Problem 3 is solved because the angle is fixed automatically by using the repulsive force of the spring.
4. Problem 4 is solved by providing a rake section mounting plate and changing the rake section according to the work.
[0005]
The scoop of the present invention has the following effects.
1. When digging a deep vertical hole with a conventional scoop Although it is possible to dig and crush earth and sand, it was necessary to dig the upper part of the hole more widely than necessary to put the crushed earth on the rake The scoop of the present invention changes the angle of the handle and the rake by moving the handle back and forth, and places the earth and sand on the rake to scoop up, so that it is not necessary to dig the upper part of the hole more widely than necessary.
2. With the removal of the vertical hole and the removal of earth and sand accumulated in a small hole such as a hum pipe, the angle between the handle and the rake part is changed several times by changing the number of gear teeth in the angle changing mechanism. The thing can remove the earth and sand inside.
3. By fixing the angle between the handle and the rake portion at a predetermined position, it can be used as a hoe, etc. Further, by changing the rake portion according to the work, it can be used for agriculture, civil engineering, and household goods for multipurpose.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
(1) Next, an embodiment of the present invention will be described with reference to FIG.
At the first position, the 5 rake portion is inserted into the earth and sand and the 1 handle portion is pushed forward. When the 5 rake portion is fixed by the earth and sand, the handle is shifted to the second shaft around the 3f gear shaft at the center of the 3e gear. Rotate to the position. At this time, the 3d gear fixed valve moves on the tooth surface of the 3e gear to the tooth before sliding due to the contraction of the upper 3c spring. At this point, the 3d gear fixed valve is caught in the gear by the repulsive force of the 3c spring, and when the handle is pulled to the third position, the 3d-1 rear part of the gear fixed valve and the 3e-1 gear front face are perpendicular to the gear axis, so the gear is fixed. The surface cannot be slipped, the 3e gear rotates in the same manner as the rotation of one shaft about the 3f gear shaft, and as a result, the 4 rake portion fixed plate that moves integrally with the 3e gear moves the 5th rake portion to the fourth position. Move to By repeating this operation, the angle of the five rake portions and the angle of one pattern can be changed as desired. To remove the angle of 5 rakes and 1 pattern after removing the soil, pull the 2a puller at the top of 1 pattern, 2b pull the 3c spring by the length pulled by the wire, and 3d gear When the fixed valve rises upward and is cut off from the 3e gear, when the angle of 5 rakes and 1 pattern comes to the desired position, when the 2a puller is released, the 3d gear fixed valve turns the 3e gear into a 3g gear hardened by the repulsive force of the 3c spring. Fix rotation.
(2) Next, description will be made with reference to the attached drawing 4.
In order to prevent earth and sand from entering the angle changing mechanism, 3j hard rubber packing is used between the 3a angle changing mechanism side plate and the 3h bearing to prevent earth and sand from being caught.
[0007]
【The invention's effect】
The angle change mechanism is sealed by the side plate to prevent the intrusion of earth and sand, and by moving the handle back and forth, the angle between the handle and the rake can be changed. As a result, operability was improved and work efficiency was improved.
A rake section mounting plate was provided, and the rake section was changed according to the work, so that it could be used for various types of work.
