Description

本発明は、畝に植えられた葉たばこ等の残幹を掘り起こして細断する処理を施す残幹処理機に関する。   The present invention relates to a remaining trunk processing machine that performs a process of digging up and cutting a remaining trunk such as leaf tobacco planted in a cocoon.

処理対象となる葉たばこや茶等は、葉部のみを収穫する作物である。このような作物は、収穫後に圃場の畝に根付いたままの幹が残されることになるが、新たに作物の栽培を行うためにはこの残幹を処理して畝を栽培可能な状態に戻す必要がある。この残幹処理の方法としては、残幹を土中に鋤き込むことが考えられるが、特に葉たばこ等は、残幹の根部に立ち枯れ病の菌が繁殖することが指摘されており、この残幹を根部ごと畝から引き抜いて回収することが推奨されている。   Leaf tobacco, tea, and the like to be processed are crops that harvest only the leaves. Such a crop will leave a stem that remains rooted in the vine after harvesting, but in order to cultivate a new crop, the remaining stem is treated to return the cocoon to a state where it can be cultivated. There is a need. As a method for this residual stem treatment, it is conceivable that the residual trunk is sown into the soil, but it has been pointed out that leaf tobacco, especially leaf tobacco, grows at the root of the residual trunk. It is recommended that the trunk be pulled out of the heel and recovered.

For this reason, when the fastening jig 3 is loosened and the base 81a is moved in the vertical direction, the position of the tip 81b can be arranged at a desired vertical position and front-rear position.

下部枠体１１の後側下部には、図５（ａ）（平面図）及び図５（ｂ）（側面図）に示すように、残幹Ｚが掘り起こされた畝Ｕの表面を均す均平装置８５が取り付けられている。 As shown in FIG. 5 (a) (plan view) and FIG. 5 (b) (side view), the lower part of the lower frame 11 has a leveling surface that smoothes the surface of the ridge U from which the remaining trunk Z has been dug up. A flat device 85 is attached .

次に、本発明に係わる残幹処理機１によって畝Ｕに植えられた残幹Ｚの残幹処理作業を行う動作について説明する。図３に示すように、先ず、走行機体９０の後部に残幹処理機１を装着し、走行機体９０が畝Ｕを跨ぐことができる位置に走行機体９０を設置する。そして、走行機体９０を畝Ｕに沿って前進動させるとともに、走行機体９０からの動力を残幹処理機１の入力部２７に伝達させる。残幹処理機１に動力が伝達されると、図４（ａ）に示すように、掘起ロータ３２がアップカット方向（矢印Ａ方向）に回転動し、送りローラ４５が矢印Ｂ方向に回転する。そして、このような状態で走行機体９０が前進動すると、残幹Ｚの茎部Ｚｋは走行機体９０の前進動によって前側に向けて押し倒される。ここで、前側に向けて押し倒された残幹Ｚの茎部Ｚｋが左右方向に傾いていると、この茎部Ｚｋは誘導部材８１によって傾きが矯正されて機体幅方向中央寄りに誘導される。このため、残幹Ｚは左右方向に傾きの小さい状態で機体内に引き込まれることになり、残幹Ｚの機体内への引き込みを確実にすることができる。   Next, the operation | movement which performs the residual stem processing operation | work of the residual stem Z planted in the fence U by the residual stem processing machine 1 concerning this invention is demonstrated. As shown in FIG. 3, first, the remaining trunk processor 1 is attached to the rear portion of the traveling machine body 90, and the traveling machine body 90 is installed at a position where the traveling machine body 90 can straddle the ridge U. Then, the traveling machine body 90 is moved forward along the heel U, and the power from the traveling machine body 90 is transmitted to the input unit 27 of the remaining trunk processor 1. When power is transmitted to the remaining trunk processor 1, the excavation rotor 32 rotates in the upcut direction (arrow A direction) and the feed roller 45 rotates in the arrow B direction as shown in FIG. To do. When the traveling machine body 90 moves forward in such a state, the stem Zk of the remaining trunk Z is pushed down toward the front side by the forward movement of the traveling machine body 90. Here, when the stem Zk of the remaining trunk Z pushed down toward the front side is inclined in the left-right direction, the inclination of the stem Zk is corrected by the guide member 81 and guided toward the center in the body width direction. For this reason, the remaining trunk Z is pulled into the aircraft with a small inclination in the left-right direction, and the remaining trunk Z can be reliably pulled into the aircraft.

誘導部材８１によって傾きが矯正された残幹Ｚは、掘起ロータ３２によってその根部Ｚｎが下側から上側へすくい上げられて掘り起こされると共に、根部Ｚｎが先行するようにして掘起爪３４の回転方向下流側に引き込まれる。そして、根部Ｚｎが掘起ロータ３２の上部側に引き込まれて移動すると、送りローラ４５によってさらに機体側に引き込まれる。送りローラ４５は、掘起ロータ３２と対向して配置されるとともに、掘起ロータ３２と対向する側において掘起ロータ３２と同一方向に回転しているので、掘起ロータ３２と相まって根部Ｚｎを挟持するようにして後方側に送り出す。また、送りローラ４５は、掘起ロータ３２によって掘り起こされた残幹Ｚがなおも掘起ロータ３２に接触することによる残幹Ｚの上下動を押さえ込み、残幹Ｚを後方側に送って残幹処理に供して、残幹処理作業の作業性を向上させることができる。   The remaining trunk Z whose inclination is corrected by the guide member 81 is digged up by scooping up the root Zn from the lower side to the upper side by the digging rotor 32, and the rotation direction of the digging claw 34 so that the root Zn precedes. It is drawn downstream. Then, when the root Zn is drawn and moved to the upper side of the digging rotor 32, it is further drawn to the machine body side by the feed roller 45. The feed roller 45 is disposed facing the digging rotor 32 and rotates in the same direction as the digging rotor 32 on the side facing the digging rotor 32. Send it to the rear side so as to hold it. Further, the feed roller 45 suppresses the vertical movement of the remaining trunk Z caused by the remaining trunk Z digged up by the digging rotor 32 still contacting the digging rotor 32, and sends the remaining trunk Z to the rear side to send the remaining trunk Z. For the processing, the workability of the remaining trunk processing work can be improved.

そして、残幹Ｚはその根部Ｚｎが先行するようにして一対の第１ローラ５１間に挿入されて、一対の第１ローラ５１によって挟持されながら後方側に搬送される。そして第１ローラ５１により搬送された残幹Ｚは、一対の第２ローラ５２によって挟持されながら後方側に搬送されて切断ロータ５６側へ送り出される。そして、第２ローラ５２から送り出された残幹Ｚは回転動する切断ロータ５６によって細断され、残幹Ｚの断片は、図１に示すブロワ５９によって吐出されてシュータ６０内に入り、シュータ６０内を上昇してシュータ６０の上端部から吐出されて収容部７０内に収容される。   Then, the remaining trunk Z is inserted between the pair of first rollers 51 so that the root portion Zn precedes, and conveyed to the rear side while being sandwiched between the pair of first rollers 51. The remaining trunk Z transported by the first roller 51 is transported to the rear side while being sandwiched between the pair of second rollers 52 and sent to the cutting rotor 56 side. The remaining trunk Z sent from the second roller 52 is shredded by a rotating cutting rotor 56, and fragments of the remaining trunk Z are discharged by the blower 59 shown in FIG. The inside is raised and discharged from the upper end portion of the shooter 60 and accommodated in the accommodating portion 70.

また、このような残幹処理作業とともに、図５（ａ）に示すように、均平装置８５によって残幹Ｚが掘り起こされた畝Ｕの表面が均平に均される。 Further, along with such a remaining stem processing operation, as shown in FIG. 5A, the surface of the ridge U from which the remaining stem Z is dug up by the leveling device 85 is leveled .

このようにして、畝Ｕに植えられた残幹Ｚは走行機体９０の前進動とともに連続的に処理される。   In this way, the remaining trunk Z planted in the basket U is continuously processed along with the forward movement of the traveling machine body 90.

なお、図１に示すように、後輪１４は機体フレーム１０に対して上下方向に位置調整可能に設けられているので、後輪１４の位置を機体フレーム１０に対して上下移動させた状態で残幹処理機１を走行機体９０に装着すると、掘起ロータ３２の耕耘深さを調整することができる。このため、畝Ｕに植えられた残幹Ｚの根部Ｚｎの張り出し深さに応じて掘起ロータ３２の耕耘深さを調整することができ、残幹Ｚの根部Ｚｎを確実に畝Ｕから掘り起こす処理を行うことができる。   As shown in FIG. 1, the rear wheel 14 is provided so that the position of the rear wheel 14 can be adjusted in the vertical direction with respect to the body frame 10, so that the position of the rear wheel 14 is moved up and down with respect to the body frame 10. When the remaining trunk processing machine 1 is mounted on the traveling machine body 90, the tilling depth of the excavation rotor 32 can be adjusted. For this reason, the tilling depth of the excavation rotor 32 can be adjusted according to the overhanging depth of the root Zn of the remaining trunk Z planted in the fence U, and the root Zn of the remaining trunk Z is reliably dug up from the fence U. Processing can be performed.

また、前述したように切断装置４０は機体フレーム１０から独立的に構成されているので、切断装置４０と機体フレーム１０とを別々に組み立てることができ、残幹処理機１の組み立て作業を容易にすることができる。さらに、切断装置４０を機体フレーム１０から取り外すことで、切断装置単体として使用することができる。また、切断装置４０をメンテナンスする場合、切断装置４０を機体フレーム１０から脱着すれば、切断装置４０のメンテナンス作業を容易に行うことができる。   Further, as described above, since the cutting device 40 is configured independently from the body frame 10, the cutting device 40 and the body frame 10 can be assembled separately, and the assembly work of the remaining trunk processing machine 1 can be easily performed. can do. Furthermore, by removing the cutting device 40 from the machine body frame 10, it can be used as a cutting device alone. Further, when maintenance is performed on the cutting device 40, if the cutting device 40 is detached from the body frame 10, maintenance work on the cutting device 40 can be easily performed.

さらに、前述した実施の形態では、残幹処理機１は走行機体９０に牽引されるタイプのものを示したが、残幹処理機１は自走可能に構成されてもよい。この場合、誘導部材８１の前方に、残幹Ｚを前側に押し倒すことができる部材を設ける。   Furthermore, in the above-described embodiment, the remaining trunk processor 1 is of a type that is pulled by the traveling machine body 90, but the remaining trunk processor 1 may be configured to be capable of traveling. In this case, a member that can push down the remaining trunk Z forward is provided in front of the guide member 81.
