Further, it is composed of a plurality of hollow cross ropes 1 and 1, and one cross rope 1 (1A) and the other cross rope 1 (1B) are sequentially connected by a connecting portion 20 to form a closed loop (annular). is doing.

先ず、連結部20の構成及び形成方法について説明する。
図4に示すように、2本のクロスロープ1,1の内、一方のクロスロープ1Aの一端部11側の先端12と、他方のクロスロープ1Bの他端部13側の先端14を、接近させて配設する。各先端12,14に粘着テープ等を巻着してほつれを防止している。
クロスロープ1は、多数本の合成繊維から成るストランド10を、2本(束)1組として、その組を交互に重ね合わせて(組み込んで)中空状(円筒網袋状)に形成された、六つ打ち、又は、八つ打ち、或いは12打ち合成繊維ロープとも呼ばれるものである。例えば、シーアンカー、ブイロープ、定置網等に使用されている。合成繊維は、例えば、ポリアシド系ナイロン、ポリエチレン、ビニロン、ポリプロピレン等である。なお、十分な強度を得るために、本発明は、12本(束)のストランド10から成るクロスロープ1(12打ち合成繊維ロープ)を使用するのが好ましい。なお、クロスロープ1(1A,1B)を以下「ロープ」と呼ぶ場合もある。
First, the configuration and forming method of the connecting portion 20 will be described.
As shown in FIG. 4, the tip 12 on the one end 11 side of one cross rope 1A and the tip 14 on the other end 13 side of the other cross rope 1B are approached. Arranged. Adhesive tape or the like is wrapped around each end 12, 14 to prevent fraying.
The cross rope 1 is formed in a hollow shape (cylindrical mesh bag shape) by superposing (incorporating) the strands 10 made of a large number of synthetic fibers into one pair (bundle) and alternately superimposing (incorporating) the pair. It is also called a six-punch, eight-punch, or twelve-pitch synthetic fiber rope. For example, it is used for sea anchors, buoy ropes, stationary nets and the like. Synthetic fibers are, for example, polyacid nylon, polyethylene, vinylon, polypropylene and the like. In order to obtain sufficient strength, the present invention preferably uses a cross rope 1 (12-strand synthetic fiber rope) composed of 12 (bundle) strands 10. The cross rope 1 (1A, 1B) may be hereinafter referred to as “rope”.

図5に示すように、他方のロープ1Bの他端部13側の先端14を、棒状の挿入治具8に接続する。
挿入治具8は、軽量・小型な携帯自在であって、図3及び図5に示すように、半球状の先端丸型に形成された先端部81と、先端部81から基端部84へ向かうストレート状の導入部(ストレート状ガイド部)82と、導入部82の直径から次第に拡径して基端部84と接するテーパ部83と、を有している。基端部84は導入部82より大径に形成され、基端面84a側に開口すると共にロープ1が差し込まれる保持孔85を有している。また、保持孔85は、ロープ1の自然状態乃至ラジアル方向圧縮縮径状態の直径より小さな寸法の内径寸法で形成されている。また、保持孔85は、ロープ1の差込量を規制する当り用の底面85aを有している。また、基端部84及びテーパ部83を半割り状にするスリット86を設けている。
図5に示すように、例えば、他方のロープ1Bの先端14を保持孔85に差し込むと、スリット86によって保持孔85が拡径すると共に復元力(バネ力)によって、他方のロープ1Bの先端14及び他端部13をコレットのように挟持状に保持して抜けを防止する。
As shown in FIG. 5, the tip 14 on the other end 13 side of the other rope 1 </ b> B is connected to a rod-shaped insertion jig 8.
The insertion jig 8 is lightweight and small and portable. As shown in FIGS. 3 and 5, the insertion jig 8 has a distal end portion 81 formed in a hemispherical distal end round shape and from the distal end portion 81 to the proximal end portion 84. It has a straight introduction portion (straight guide portion) 82 that faces, and a tapered portion 83 that gradually increases in diameter from the diameter of the introduction portion 82 and contacts the base end portion 84. The base end portion 84 is formed to have a larger diameter than the introduction portion 82, and has a holding hole 85 that opens to the base end face 84a side and into which the rope 1 is inserted. The holding hole 85 is formed with an inner diameter smaller than the diameter of the rope 1 in the natural state or in the radial compression-reduced state. Further, the holding hole 85 has a bottom surface 85a for hitting that regulates the insertion amount of the rope 1. Further, a slit 86 is provided that divides the base end portion 84 and the taper portion 83 into a half.
As shown in FIG. 5, for example, when the tip 14 of the other rope 1B is inserted into the holding hole 85, the diameter of the holding hole 85 is expanded by the slit 86 and the restoring force (spring force) causes the tip 14 of the other rope 1B. The other end 13 is held like a collet to prevent it from coming off.

図6に於て、一方のロープ1Aの一端部11を、長手方向に圧縮して蛇腹状に内径を拡径すると共に、ストランド10とストランド10の間の織目(編目)を広げる。ロープ1Bと接続した挿入治具8の先端部81及び導入部82を、長手一方向N1に、拡径したロープ1Aの一端部11に挿通させる。こうすることで、一方のロープ1Aの先端12をほぐして(ストランド10毎に分けて)、先端開口部を形成して他方のロープ1Bを挿入する必要がなくなり作業性が向上する。   In FIG. 6, one end 11 of one rope 1A is compressed in the longitudinal direction to increase the inner diameter in a bellows shape, and the texture (knitting) between the strand 10 and the strand 10 is expanded. The distal end portion 81 and the introduction portion 82 of the insertion jig 8 connected to the rope 1B are inserted through the one end portion 11 of the rope 1A having an enlarged diameter in one longitudinal direction N1. By doing so, it is not necessary to loosen the tip 12 of one rope 1A (divided for each strand 10) to form a tip opening and insert the other rope 1B, thereby improving workability.

図7に示すように、一方のロープ1Aの一端部11に、挿入治具8の基端部84と共に他方のロープ1Bの先端14を挿入する。テーパ部83によって、一方のロープ1Aの一端部11が拡径してスムーズに基端部84が挿入される。
図8に示すように、挿入治具8及び他方のロープ1Bの先端14を、一方のロープ1Aの一端部11に挿入した位置から長手方向に所定寸法差し込んだ後に、ストランド10とストランド10の織目から長手一方向N1に引いて挿通させる。
As shown in FIG. 7, the distal end 14 of the other rope 1B is inserted into the one end 11 of one rope 1A together with the base end 84 of the insertion jig 8. By the taper portion 83, the one end portion 11 of the one rope 1A is expanded in diameter, and the base end portion 84 is smoothly inserted.
As shown in FIG. 8, after inserting the insertion jig 8 and the tip 14 of the other rope 1B into the longitudinal direction from the position where it is inserted into one end 11 of the one rope 1A, the strand 10 and the strand 10 are woven. It is pulled through the eye in one longitudinal direction N1 and inserted.

図9に示すように、他方のロープ1Bの先端14から挿入治具8を取り外す。そして、他方のロープ1Bを長手他方向N2に引き戻し、他方のロープ1Bの先端14を、一方のロープ1Aの一端部11に収納させる。
図10に示すように、他方のロープ1Bの先端14を内有する一方のロープ1Aの一端部11を、長手方向に引っ張る。すると、一方のロープ1Aの一端部11が縮径し、他方のロープ1Bの先端14を締め付けて摩擦力を増加させ、一方のロープ1Aのストランド10と他方のロープ1Bのストランド10が互いに係止し(かみ合って)、さらに、挿通した箇所の織目が閉じて織目を挿通したロープ1を挟圧して、抜けが防止される。
As shown in FIG. 9, the insertion jig 8 is removed from the tip 14 of the other rope 1B. Then, the other rope 1B is pulled back in the other longitudinal direction N2, and the tip 14 of the other rope 1B is stored in one end 11 of the one rope 1A.
As shown in FIG. 10, one end 11 of one rope 1A having the tip 14 of the other rope 1B is pulled in the longitudinal direction. Then, one end 11 of one rope 1A is reduced in diameter, the tip 14 of the other rope 1B is tightened to increase the frictional force, and the strand 10 of one rope 1A and the strand 10 of the other rope 1B are locked together. However, the texture of the inserted portion is closed and the rope 1 inserted through the texture is pinched to prevent the slippage.

そして、図11に示すように、一方のロープ1Aの先端12と挿入治具8を接続し、他方のロープ1Bの他端部13を拡径させ、上述のように挿入治具8を操作して、他方のロープ1Bの他端部13に、一方のロープ1Aの先端12を収納させて、他方のロープ1Bの他端部13を長手方向に引っ張る。
すると、図12に示すように、一方のロープ1Aの先端12が他方のロープ1Bの他端部13に接続し、他方のロープ1Bの先端14が一方のロープ1Aの一端部11に接続された、連結部20が形成される。そして、複数本のロープ1,1を、順次接続して(連結部20を形成して)閉ループ状の搬送ロープ2が形成される。
Then, as shown in FIG. 11, the tip 12 of one rope 1A and the insertion jig 8 are connected, the other end 13 of the other rope 1B is expanded in diameter, and the insertion jig 8 is operated as described above. Then, the other end 13 of the other rope 1B is accommodated with the tip 12 of one rope 1A, and the other end 13 of the other rope 1B is pulled in the longitudinal direction.
Then, as shown in FIG. 12, the tip 12 of one rope 1A is connected to the other end 13 of the other rope 1B, and the tip 14 of the other rope 1B is connected to one end 11 of the one rope 1A. The connecting portion 20 is formed. Then, a plurality of ropes 1, 1 are sequentially connected (forming the connecting portion 20) to form a closed loop-shaped transport rope 2.

また、一方のロープ1Aの一端部11を長手方向に圧縮すれば、一方のロープ1Aの内径が拡径すると共にストランド10とストランド10の間が開いて、スムーズに他方のロープ1Bの先端14が引き抜かれる。また、他方のロープ1Bの他端部13を長手方向に圧縮すれば、他方のロープ1Bの内径が拡径すると共にストランド10とストランド10の間が開いて、スムーズに一方のロープ1Aの先端12が引き抜かれる。連結部20の接続は容易に解除される。
この連結部20は、容易に接続・分離でき、かつ、長手方向の引張り力に強い。また、最も太い箇所でも連結部20の中央部20aでロープ2本程度と成り、後述の滑車3及び回転ドラム5との間で引っ掛かり等の不具合が防止される。
Further, if one end 11 of one rope 1A is compressed in the longitudinal direction, the inner diameter of one rope 1A is expanded and the space between the strand 10 and the strand 10 is opened, and the tip 14 of the other rope 1B is smoothly moved. Pulled out. Also, if the other end 13 of the other rope 1B is compressed in the longitudinal direction, the inner diameter of the other rope 1B is increased and the space between the strand 10 and the strand 10 is opened, so that the tip 12 of the one rope 1A is smooth. Is pulled out. The connection of the connecting portion 20 is easily released.
The connecting portion 20 can be easily connected and disconnected, and has a strong tensile force in the longitudinal direction. Further, even at the thickest part, there are about two ropes at the central portion 20a of the connecting portion 20, and problems such as catching between the pulley 3 and the rotating drum 5 described later are prevented.

また、搬送ロープ2は、図13に示すように、伐採材Wが掛けられる引掛部21を有している。
図14に示すように、可撓性を有する紐体7の一端7aと他端7bを、所定の間隔をもって、クロスロープ1の軸心略直交方向からストランド10とストランド10の間を挿通させ、クロスロープ1を挿通した一端7a側部と他端7b側部を、図13に示すように、結束して、垂下状の吊り輪を形成している。この吊り輪状の引掛部21に、伐採材Wと連結したフック部材79を係止させることで、搬送ロープ2で伐採材Wを牽引する。
このように、紐体7を用いることで後述の回転ドラム5との間で引っ掛かり等の不具合が防止される。また、フック部材79で引っ掛けるだけで連結でき、作業性を向上させている。また、クロスロープ1と紐体7を工具なしで接続でき、引掛部21を容易に増減できる。また、引掛部21と引掛部21の間隔寸法を容易に変更できる。
Further, as shown in FIG. 13, the transport rope 2 has a hook portion 21 on which the felling material W is hung.
As shown in FIG. 14, one end 7a and the other end 7b of the flexible cord body 7 are inserted between the strand 10 and the strand 10 from the direction substantially perpendicular to the axis of the cross rope 1 with a predetermined interval. The one end 7a side portion and the other end 7b side portion inserted through the cross rope 1 are bundled as shown in FIG. 13 to form a hanging suspension ring. By hooking the hook member 79 connected to the felling material W to the hanging ring-shaped catching portion 21, the felling material W is pulled by the transport rope 2.
In this way, the use of the string 7 prevents problems such as catching with the rotary drum 5 described later. Further, it is possible to connect by simply hooking with the hook member 79, and the workability is improved. Moreover, the cross rope 1 and the string body 7 can be connected without a tool, and the hook portion 21 can be easily increased or decreased. Further, the distance between the hook portion 21 and the hook portion 21 can be easily changed.

また、図1及び図2に於て、搬送ロープ2を周回駆動させる回転ドラム5と、搬送ロープ2に適度な張り(テンション)を付与するウインチ(巻取り機)6と、パワーシャベル等の建設機械や林内作業車等のエンジンや油圧モータ又は電気モータ等の駆動源Eと、回転ドラム5とウインチ6を夫々操作可能な操作部9と、を備えている。駆動源Eと回転ドラム5とウインチ6と操作部9は、履帯を有する自走可能なパワーショベル等の建設機械や林内作業車等に設けられている。   1 and 2, the construction of a rotating drum 5 for driving the conveyor rope 2 around, a winch (winding machine) 6 for applying an appropriate tension to the conveyor rope 2, and a power shovel.

The winch 6 is provided in the vicinity of the rotating drum 5 and applies tension to the closed-loop conveyance rope 2 via a tension pulley 3 (3A).
Further, in order to make the retracting direction of the rotating drum 5 and the pulling direction of the winch 6 the same direction, a folding pulley 3 (3B) is provided between the rotating drum 5 and the winch 6.

また、搬送ロープ2は、伐採地Jと集材地Sの間に設けた多数の架設部30に懸架されている。搬送ロープ2は、集材地Sから伐採地Jにわたって閉ループ状に懸架(張架)されている。
図15に示すように、架設部30は、伐採地Jと集材地Sに存在する樹木や竹等又は打設した杭等から成る支柱部31と、支柱部31に巻設され可撓性の帯状乃至紐状体を有する締め付けベルト等の締結部材32と、搬送ロープ2が懸架される回転体(プーリ)39を有する滑車3と、から成る。
Further, the transport rope 2 is suspended by a number of erection parts 30 provided between the felling land J and the logging area S. The transport rope 2 is suspended (suspended) in a closed loop from the logging area S to the felling area J.
As shown in FIG. 15, the erection unit 30 includes a column 31 composed of trees, bamboo, or the like existing in the logging area J and the logging area S, and a column 31 wound around the column 31 and is flexible. A fastening member 32 such as a fastening belt having a belt-like or string-like body, and a pulley 3 having a rotating body (pulley) 39 on which the transport rope 2 is suspended.

図15(a)に示すように、滑車3は、締結部材32によって支柱部31に水平軸心La廻りに揺動自在に取着されている。搬送ロープ2にテンションが付与されていない自然状態では、支柱部31に締結部材32を介して垂下状に設けられている。搬送ロープ2にテンションが付与されると、図15(b)に示すように、回転体39側が上方へ揺動し、回転体39の回転軸心L3が鉛直状に回転可能となる。なお、鉛直状とは、水平面に対して、60度乃至120度の範囲を言う。   As shown in FIG. 15A, the pulley 3 is attached to the column 31 by a fastening member 32 so as to be swingable about the horizontal axis La. In a natural state where no tension is applied to the transport rope 2, the support rope 31 is provided in a suspended shape via a fastening member 32. When tension is applied to the transport rope 2, as shown in FIG. 15B, the rotating body 39 side swings upward, and the rotation axis L3 of the rotating body 39 can be rotated vertically. The vertical shape means a range of 60 degrees to 120 degrees with respect to the horizontal plane.

滑車3は、軽量・小型で持ち運び自在である。図16と図17に示すように、回転体39の円周凹溝39dから搬送ロープ2が下方に脱落するのを防止する底壁部39aを有している。底壁部39aを、回転軸心L3周りに所定の間隔で上下方向に開口する切欠部39bを形成したスプロケット状(歯車状)に設けている。言い換えると、回転体39の底面側に、搬送ロープ2が下方に脱落するのを防止する係止突片39cを回転軸心L3周りに所定の間隔に設けている。
搬送ロープ2の引掛部21が回転体39に懸架される際に、吊り輪状の紐体7が、切欠部39b(係止突片39cと係止突片39cの間)から垂れ下がり、回転体39に引っ掛かることなく、垂下状態が保持され、搬送ロープ2のスムーズな周回駆動を可能にする。
The pulley 3 is lightweight, small and portable. As shown in FIG. 16 and FIG. 17, it has the bottom wall part 39a which prevents that the conveyance rope 2 falls below from the circumferential groove 39d of the rotary body 39. As shown in FIG. The bottom wall portion 39a is provided in a sprocket shape (gear shape) in which cutout portions 39b that open in the vertical direction at predetermined intervals around the rotation axis L3 are formed. In other words, locking protrusions 39c that prevent the transport rope 2 from dropping downward are provided on the bottom surface side of the rotating body 39 around the rotation axis L3 at a predetermined interval.
When the hooking portion 21 of the transport rope 2 is suspended on the rotating body 39, the suspension ring-like string body 7 hangs down from the notch 39b (between the locking protrusion 39c and the locking protrusion 39c), and the rotating body 39 The hanging state is maintained without being caught by the conveyor rope 2 and smooth rotation of the transport rope 2 is enabled.

次に、伐採材搬出装置の作用及び伐採材搬出方法について説明する。
図18に示すように、トラック等の運搬車両が侵入可能な集材地Sに、駆動源E、回転ドラム5、ウインチ6、操作部9、を設ける。また、集材地Sと伐採地Jに多数の架設部30を設ける。また、搬送ロープ2を、架設部30の滑車3に懸架すると共に回転ドラム5に複数回巻設する。集材地Sと伐採地Jの間(集材地Sから伐採地Jにわたって)で搬送ロープ2を閉ループ状にして周回駆動させる。
搬送ロープ2が通過する架設ルートは、樹木や竹等伐採対象物の近傍を通るように設ける。伐採材Wは、図13に示すように、搬送ロープ2の引掛部21にフック部材79を介して連結され、搬送ロープ2によって牽引され集材地Sまで搬出される。
Next, operation and lumber method for carrying out harvesting adopted material carry-out device will be described.
As shown in FIG. 18, a drive source E, a rotating drum 5, a winch 6, and an operation unit 9 are provided in a gathering ground S into which a transport vehicle such as a truck can enter. In addition, a large number of erection parts 30 are provided in the logging area S and the logging area J. Further, the transport rope 2 is suspended on the pulley 3 of the erection unit 30 and wound around the rotary drum 5 a plurality of times. Between the logging area S and the felling area J (from the logging area S to the felling area J), the transport rope 2 is driven in a closed loop.
The erection route through which the transport rope 2 passes is provided so as to pass through the vicinity of an object to be felled such as a tree or bamboo. As shown in FIG. 13, the felled material W is connected to the hooking portion 21 of the transport rope 2 via the hook member 79, pulled by the transport rope 2, and carried out to the gathering site S.

そして、搬送ロープ2の架設ルート近傍の伐採が終了し、次の伐採対象物の近傍まで、懸架ルートを延長・増設する。
ここで、伐採地Jは山間部や里山(人家の裏山)のため、伐採材Wが搬送される際に障害となる、大きな岩Q1、急な窪地Q2、家屋、あるいは伐採しない樹木や竹等の非伐採対象物Q3といった障害物Qが存在する。特に、岩Q1等は図面上では予測不可能であるため、搬送ロープ2の長さを現場にて臨機応変に延長して増設する必要がある。
Then, the cutting of the transportation rope 2 near the erection route is completed, and the suspension route is extended / added to the vicinity of the next object to be harvested.
Here, because the logging area J is a mountainous area or a satoyama (back mountain of a house), large rocks Q1, steep depressions Q2, houses, or trees and bamboos that are not cut, which are obstacles when the logging material W is transported There is an obstacle Q such as the non-cutting object Q3. In particular, since the rock Q1 and the like are unpredictable on the drawing, it is necessary to extend the length of the transport rope 2 on the spot as needed.

そこで、搬送ロープ2の連結部20の一方のロープ1Aの一端部11及び他方のロープ1Bの他端部13を長手方向に圧縮させ、各先端12,14を引き抜いて接続を解除する。閉ループ状の搬送ロープ2は、油圧カッター等の大型で駆動源の必要な切断機械を用いずに容易に分断される。
そして、クロスロープ1の本数を追加して順次連結部20を形成することで、所望長さの搬送ロープ2が得られる。特別な接続金具を使用したり、複雑に編み込むアイスプライスを形成せずに、接続される。
Therefore, one end 11 of one rope 1A of the connecting portion 20 of the transport rope 2 and the other end 13 of the other rope 1B are compressed in the longitudinal direction, and the tips 12 and 14 are pulled out to release the connection. The closed loop-shaped transport rope 2 is easily divided without using a large-sized cutting machine such as a hydraulic cutter that requires a drive source.
And the conveyance rope 2 of desired length is obtained by adding the number of the cross ropes 1 and forming the connection part 20 one by one. It is connected without using special connection fittings or forming an ice price that weaves intricately.

また、架設部30は、滑車3を締結部材32で架設ルート近傍の樹木等の支柱部31に結束させるだけなので、取付・取り外しが容易に行われ、架設ルートの変更をより迅速にする。
また、集材地Sに、回転ドラム5やウインチ6、駆動源E、操作部9が配置され、伐採地J側には、搬送ロープ2を駆動させる機械やテンションを負荷する機械等が必要ないので、伐採地J内での架設ルートの変更を容易にする。
Further, since the erection unit 30 only binds the pulley 3 to the support column 31 such as a tree in the vicinity of the erection route with the fastening member 32, the erection / removal can be easily performed and the erection route can be changed more quickly.
Moreover, the rotating drum 5, the winch 6, the drive source E, and the operation part 9 are arrange | positioned in the gathering place S, and the machine which drives the conveyance rope 2, the machine which loads a tension | tensile_strength, etc. are unnecessary on the felling land J side. Therefore, it is easy to change the erection route within the logging area J.

また、架設ルートを、回転ドラム5の引込み方向と平行状に走行する本線部29と、本線部29に直交状に走行する枝線部28と、を有する凸の字状に設け、図18(a)から図18(b)のように、本線部29を伐採地Jの奥部に延伸させ、本線部29の延伸に伴って枝線部28を波の移動のように平行移動させて順次変更させるのが効率的で好ましい。
また、図18(b)のような、予め、長い架設ルートを形成した後、伐採作業を進めながら、集材地Sに接近させて架設ルートを短縮・減少させて、図18(a)のように変形(変更)させても良い。
Further, the installation route is provided in a convex shape having a main line portion 29 that travels parallel to the pulling direction of the rotary drum 5 and a branch line portion 28 that travels perpendicular to the main line portion 29, as shown in FIG. As shown in FIG. 18 (b), the main line 29 is extended to the back of the felling area J, and the branch line 28 is moved in parallel as a wave moves along with the extension of the main line 29. It is efficient and preferable to change.
Also, after forming a long erection route as shown in FIG. 18 (b) in advance, while proceeding with the felling operation, the erection route is shortened or reduced by approaching the logging site S, and as shown in FIG. 18 (a). You may make it change (change).

また、図18(b)に一点鎖線で示したような不要架設ルート90部分の搬送ロープ2の一部を、使用する架設ルートから分離し、分離箇所Vを直結するように接続して、不要架設ルート部分の片づけ作業と、増設作業を略同時に行っても良い。
また、作業終了後に、連結部20の接続を解除して、複数本のクロスロープ1に分離してから片づけても良い。長尺状の搬送ロープ2を回収するよりも手間や時間が軽減できる。
Also, a part of the transport rope 2 of the unnecessary erection route 90 as shown by the one-dot chain line in FIG. 18 (b) is separated from the erection route to be used and connected so as to directly connect the separation point V. The work for cleaning up the erection route portion and the expansion work may be performed substantially simultaneously.
Further, after the work is finished, the connection of the connecting portion 20 may be released and separated into a plurality of cross ropes 1 and then cleaned. Time and effort can be reduced compared to collecting the long transport rope 2.

また、図19に示すように、伐採地Jが、杉や檜等の植林部Kaに、斜面下方の竹林部Kbから斜面に沿って竹が侵入した場所であって、植林部Ka内の竹が伐採対象物の場合は、架設部30を斜面上位置と斜面下位置とで千鳥状に配設し、架設ルートを鋸刃状に設けるのが好ましい。架設部30の設置箇所が少なく済むと共に、斜面全体を面状にカバーでき、間伐しない杉や檜等が多くても、伐採した竹を容易に搬出することが可能となる。   In addition, as shown in FIG. 19, the logging area J is a place where bamboo has entered the plantation part Ka from the bamboo forest part Kb below the slope along the slope, and the bamboo in the plantation part Ka. In the case of an object to be cut, it is preferable that the erection part 30 is arranged in a staggered manner on the slope upper position and the slope lower position, and the erection route is provided in a saw blade shape. The installation location of the erection part 30 can be reduced, and the entire slope can be covered in a planar shape. Even if there are many cedars, firewood, etc. that are not thinned, the harvested bamboo can be easily carried out.

なお、本発明は設計変更可能であって、図7に於て、一方のロープ1Aの一端部11内に、挿入治具8と共に他方のロープ1Bの先端14を収納した後、挿入治具8のみを引き抜いて、他方のロープ1Bの先端14を、一方のロープ1Aの一端部11内に残存させて接続しても良い The design of the present invention can be changed. In FIG. 7, after inserting the insertion jig 8 and the tip 14 of the other rope 1B into the one end 11 of one rope 1A, the insertion jig 8 is inserted. Only the tip of the other rope 1B may be withdrawn, and the tip 14 of the other rope 1B may remain in the one end portion 11 of the one rope 1A .

以上のように、本発明の伐採材搬出方法は、複数本の中空状のクロスロープ1A,1Bの内、一方のクロスロープ1Aの一端部11に他方のクロスロープ1Bの他端部13側の先端14を挿入し、かつ、他方のクロスロープ1Bの他端部13に一方のクロスロープ1Aの一端部11側の先端12を挿入して、接続・分離自在な連結部20を有する搬送ロープ2を形成し、搬送ロープ2を伐採地Jと集材地Sの間で閉ループ状に懸架して周回駆動させ、伐採材Wを牽引して集材地Sまで搬出し、接続する複数本のクロスロープ1A,1Bの本数を増減させて、搬送ロープ2が懸架される架設ルートを変形させるので、搬送ロープ2を現場にて容易に延長又は短縮できる。架設ルートを地形等の周囲の環境に柔軟に対応させて自由に(順次)変更できる。油圧カッター等の大型で駆動源が必要となるような切断機械や、連結用の接続金具が必要なく、迅速かつ安価に搬送ロープ2を延長・短縮作業を行うことができる。効率良く伐採作業を行うことができる。 As described above, the felled material carrying-out method of the present invention is such that, among the plurality of hollow cross ropes 1A and 1B, one end 11 of one cross rope 1A is connected to the other end 13 side of the other cross rope 1B. A transport rope 2 having a connecting portion 20 that can be connected / separated by inserting a tip 14 and inserting a tip 12 on one end 11 side of one cross rope 1A into the other end 13 of the other cross rope 1B. The conveyor rope 2 is suspended in a closed loop between the logging area J and the logging area S and driven around, and the logging material W is pulled to the logging area S and is connected to a plurality of crosses. Since the number of the ropes 1A and 1B is increased / decreased and the installation route on which the transport rope 2 is suspended is deformed, the transport rope 2 can be easily extended or shortened on site. The erection route can be changed freely (sequentially) flexibly according to the surrounding environment such as terrain. There is no need for a large-sized cutting machine such as a hydraulic cutter that requires a drive source or a connecting fitting for connection, and the work of extending and shortening the transport rope 2 can be performed quickly and inexpensively. Logging operations can be performed efficiently.

また、搬送ロープ2を、回転駆動する回転ドラム5に複数回巻設して、搬送ロープ2を引込みつつ送り出すようにして、伐採地Jと集材地Sの間を周回駆動させるので、滑りを防止して回転ドラム5の回転力を確実に搬送ロープ2に伝達でき、エネルギー効率良く周回駆動させることができる。搬送ロープ2を閉ループ状に形成でき架設作業を容易に行うことができる。   In addition, the transport rope 2 is wound around the rotating drum 5 that is driven to rotate, and the transport rope 2 is pulled out and sent out to drive between the felling land J and the gathering land S. Thus, the rotational force of the rotating drum 5 can be reliably transmitted to the transport rope 2 and can be driven around in an energy efficient manner. The transport rope 2 can be formed in a closed loop shape, and the erection work can be easily performed.
