The shaft 2 of the rotating shaft 2 is prevented from shaking during the grinding operation with respect to the root stock 4 so that the root stock 4 can be easily opened and ground with the grinding blade 5.

図１乃至図４に示すように、例えば、掘削等の作業を行う作業機（バックホウ等）のアーム６の先端に、取付孔１ｂを有する装着部１ａを介して着脱自在にピンで取付けられるとともに、前記装着部１ａの下部に設けられた回転部７から垂設された回転軸２に直交する方向に延設された刃である粉砕刃５で伐採後の根株４を処理する、アタッチメント１である。   As shown in FIGS. 1 to 4, for example, it is detachably attached to a tip of an arm 6 of a working machine (backhoe or the like) for performing excavation or the like via a mounting portion 1a having a mounting hole 1b. In the attachment 1, the root stock 4 after cutting is treated with a pulverizing blade 5 which is a blade extending in a direction perpendicular to the rotating shaft 2 provided vertically from the rotating portion 7 provided at the lower portion of the mounting portion 1 a. is there.

前記回転軸２の先端部２ａを、軸方向で前記粉砕刃５の位置よりも先の位置に延設させて伸ばしている。そして、前記延設された先端部２ａを尖塔状に形成すると共に、該先端部２ａに、根株４に貫入促進するようにガイドし、且つ、回転軸２の軸がブレないようにするためのガイド手段である、螺旋ガイド部３を設けている。前記螺旋ガイド部３は、回転軸２に、鋼製の螺旋板を溶接等で一体化して形成される。   The front end 2a of the rotating shaft 2 is extended and extended to a position ahead of the position of the crushing blade 5 in the axial direction. And while extending the said front-end | tip part 2a in the shape of a spire, it guides to this front-end | tip part 2a so that penetration may be accelerated | stimulated, and the shaft of the rotating shaft 2 does not blur A spiral guide part 3 is provided as a guide means. The spiral guide 3 is formed by integrating a steel spiral plate on the rotary shaft 2 by welding or the like.

また、前記粉砕刃５の回転軸２に対する半径方向の端部に、前記根株４の枝根４ａを切断するため、枝根用切断刃８を前記半径方向に直交させて設けている。なお、前記回転部７の回転装置は、例えば、作業機からホースで供給される油圧で回転する油圧モーター等を始めとする回転装置である。   Moreover, in order to cut | disconnect the branch root 4a of the said root stock 4 in the radial direction edge part with respect to the rotating shaft 2 of the said crushing blade 5, the cutting blade 8 for branch roots is provided orthogonally to the said radial direction. The rotating device of the rotating unit 7 is, for example, a rotating device such as a hydraulic motor that rotates with hydraulic pressure supplied by a hose from a work machine.

以上の様にして形成されてなる木の根処理用アタッチメント１を使用すれば、図４に示すように、フェラーバンチャー等の伐採装置で立木を伐採した後、残った根株４を粉砕処理を行う。   If the tree root attachment 1 formed as described above is used, as shown in FIG. 4, after the standing tree is cut by a felling device such as a feller buncher, the remaining root stock 4 is crushed.

まず、作業機のアーム６の端部に、木の根処理用アタッチメント１における装着部１ａを、取付孔１ｂにピンを差し込んで、取付ける。作業機の油圧ホースを木の根処理用アタッチメント１のホースに接続する。   First, the mounting portion 1a of the tree root processing attachment 1 is attached to the end portion of the arm 6 of the work machine by inserting a pin into the attachment hole 1b. The hydraulic hose of the work machine is connected to the hose of the tree root treatment attachment 1.

そして、作業機のアーム６を根株４の上に持って行き、回転部７の回転装置を回転駆動させる。図４に示すように、回転軸２の先端部２ａを根株４の切り口に当てて、押し込んでいく。回転軸２は、前記先端部２ａのガイド手段の螺旋ガイド部３によって、例えば、山の斜面で伐採された様々な方向に傾いた根株４であっても、その軸がブレずに導かれて行き、根株４を安定して確実に押し開くものである。   And the arm 6 of a working machine is brought on the root stock 4, and the rotation apparatus of the rotation part 7 is rotationally driven. As shown in FIG. 4, the tip 2 a of the rotating shaft 2 is pressed against the cut end of the root stock 4 and pushed in. The rotating shaft 2 is guided by the spiral guide portion 3 of the guide means of the distal end portion 2a, for example, even if the root stock 4 is tilted in various directions felled on the slope of a mountain, and the shaft is guided without blurring. Go and push the root stock 4 stably and reliably.

前記回転軸２の回転により粉砕刃５が、押し開かれた根株４を粉砕していく。根株４は、地面１０から上の部分は勿論のこと、地面１０の下の根も粉砕される。根株４の根は、幹の大小にかかわらず地面１０に対する深さが、深くても３０ｃｍ程度であり、回転軸２を地面１０に向かって押し込んでいくことで、根株４が前記粉砕刃５で綺麗に粉砕され、土と混ざって早く土に帰るものである。なお、根株４の大きさにより、前記粉砕刃５の半径長さを変えるものである。   The crushing blade 5 crushes the root stock 4 that has been pushed open by the rotation of the rotating shaft 2. In the root stock 4, not only the portion above the ground 10 but also the root below the ground 10 is crushed. Regardless of the size of the trunk, the root 4 has a depth of about 30 cm at most even with respect to the ground 10, and the root 4 is pushed by the grinding blade 5 by pushing the rotary shaft 2 toward the ground 10. It is crushed neatly, mixed with the soil, and returned to the soil quickly. The radius length of the grinding blade 5 is changed according to the size of the root stock 4.

また、図１に示すように、前記粉砕刃５の回転軸２に対する半径方向の端部に、根株４における枝根４ａを切断するための、枝根用切断刃８を前記半径方向に直交させて設けるものである。これにより、前記粉砕刃５で根株４が粉砕されるとともに、図４に示すように、地面１０の下の枝根４ａが切断される。こうして、根株４の根掘が不要となる。   Further, as shown in FIG. 1, a branch root cutting blade 8 for cutting a branch root 4a in the root stock 4 is orthogonally crossed in the radial direction at an end portion in the radial direction with respect to the rotating shaft 2 of the grinding blade 5. Provided. As a result, the root stock 4 is pulverized by the pulverizing blade 5, and the branch root 4a below the ground 10 is cut as shown in FIG. In this way, the root excavation of the root stock 4 becomes unnecessary.

更に、図１及び図４に示すように、前記回転部７には、垂設する回転軸２の粉砕方向に沿って振動を加えることで、当該回転軸の先端部２ａが根株４を切り開き易くすべく、加振装置９が設けられている。この加振装置９の電源は、装着部１ａに設けられるとともに作業機側から無線装置で遠隔操作される独立の電源バッテリーか、若しくは、作業機側の電源バッテリー及び電線から供給される。これにより、堅い根株４であっても、根株４の開きが容易となって、粉砕作業が早くなるものである。   Further, as shown in FIGS. 1 and 4, by applying vibration to the rotating portion 7 along the pulverizing direction of the rotating shaft 2, the tip portion 2 a of the rotating shaft can easily open the root 4. In order to eliminate the problem, a vibration device 9 is provided. The vibration device 9 is supplied with power from an independent power battery provided in the mounting portion 1a and remotely operated by a wireless device from the work machine side, or from a power battery and electric wires on the work machine side. Thereby, even if it is the hard root strain 4, the opening of the root strain 4 is facilitated, and the pulverization work is accelerated.

このほか、図５乃至図７に示すように、回転軸２の先端部２ａにおけるガイド手段を、底から見ると十字状に見える、三角板ガイド部３ａを組み合わせた尖塔体とするものである。このような形状のガイド手段でも、根株４を容易に押し開いていくものである。当該三角板ガイド部３ａを、低コストで容易に作成することができる。   In addition, as shown in FIGS. 5 to 7, the guide means at the tip 2 a of the rotating shaft 2 is a spire that combines a triangular plate guide 3 a that looks like a cross when viewed from the bottom. Even with the guide means having such a shape, the root 4 is easily pushed open. The triangular plate guide 3a can be easily created at low cost.

また、図５乃至図７に示すように、粉砕刃５ａに枝根用切断刃８ａを一体的に形成するものである。切断刃８ａの取付強度も向上し、粉砕刃５ａに対して溶接等の手段で切断刃８ａを固着させる手間も省けるものである。   Further, as shown in FIGS. 5 to 7, a branch root cutting blade 8a is formed integrally with the grinding blade 5a. The mounting strength of the cutting blade 8a is also improved, and the trouble of fixing the cutting blade 8a to the grinding blade 5a by means such as welding can be saved.

本発明に係る木の根処理用アタッチメント１によれば、回転軸２の先端部２ａにガイド手段があるので、回転軸２のブレが無く、安定して根株４を粉砕することができて、根株処理に広く適用できるものである。   According to the attachment 1 for root treatment of a tree according to the present invention, since there is a guide means at the tip 2a of the rotary shaft 2, the root stock 4 can be stably crushed without any blurring of the rotary shaft 2, and the root stock processing. It can be widely applied to.
