Description

【0001】
【産業上の利用分野】
この発明は、茶園で各種の作業を行う走行型茶園管理機に関し、茶園管理作業中、肥料散布の作業を行なう肥料散布機、及び耕起作業を行なう耕起機、及び肥料散布作業と耕起作業を同時に行なう複合作業管理機に関するものであって、更に摘採作業を行う摘採機を利用して、肥料散布作業、耕起作業を行わせる複合作業管理機に関する。
【0002】
【従来の技術】
茶園において、肥料散布作業、耕起作業を行うものとしては、特開2002−101729に多目的の乗用型茶園作業車として、本願の出願人により開示されている。
【0003】
【発明が解決しようとする課題】
特開2002−101729においては、茶園での多目的作業の一部として肥料散布作業、耕起作業を行なうことが示されているが、これを実施するに当っての細かな機構は示されていない。この発明は走行型茶園管理機によって、肥料散布作業、耕起作業を実施する場合の細部の機構を提供することを課題とする。更に、特開2002−101729に示すような多種の作業を行なう多目的作業車は、現在実用化されていない。従って、この発明では、現在、最も多く使用されている乗用型茶葉摘採機を利用して、肥料散布作業、耕起作業を行なうことができるようにすることを課題とする。
【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、請求項1記載の発明では、「茶畝を挟んだ2本の走行装置を門型枠でつなぎ、機体後部に小型の肥料供給用ホッパーを設け、左右の畝間に少量ずつ肥料を散布する装置を設けた走行型茶園管理機において、肥料供給用ホッパーを上部を長方形の箱型として、上面開放可能とし、下部は半円筒型とし、円筒型底面に沿ってスクリュー軸を横架し、底面の端部に開口面積の調節が可能な開口部を設け、スクリューの回転によって肥料を開口部から放出する」という手段を用いる。この発明の走行型茶園管理機は、あくまで小規模の茶園で使用することを前提としている。特開2002−101729では、下面がベルトコンベヤで出来た肥料散布用の大きなホッパーを機体中央部に設けて、自動的に左右へ振り分け、更にその先へ肥料散布機を設けている。この発明では、大型の肥料ホッパーは設けず、肥料は肥料袋に入ったままの状態で機体中央部に積んでおき、機体後部に上面が開放可能な箱型で、下面を半円筒形とし、スクリュー軸を横架した小型の肥料供給用ホッパーを設ける。この肥料供給用ホッパーが空になると、積んである肥料袋を開き、肥料供給用ホッパーへ手で入れてやるという手段をとっている。肥料供給用ホッパーに入っている肥料は、底面に横架したスクリューの回転によってホッパーの左右の側壁へ向かって寄せられる。スクリューはねじれ方向がホッパーの左右で反対になっており、それぞれ左右の畝間に沿った方向へ寄せられ、そこに設けてある開口部より取り出される。開口部の面積を調節することで、取出量の調節が出来る。
【0005】
請求項2記載の発明では、「肥料供給用ホッパーを左の畝間用、右の畝間用の2ヶに分割し、機体と脱着可能とする」という手段を用いる。この発明の走行型茶園管理機は、小型軽量に作ってあり、小型トラックで運ぶということを前提にしている。従って、機体後部の肥料供給用ホッパーを脱着可能としておけば、運搬時には外すことによって、トラックの荷台からはみ出すことなく、運搬することが可能となる。
【0006】
請求項3記載の発明では、「機体後部に回転軸を横架し、この回転軸とエンジンにつながる回転軸をベルトクラッチにより連結して、回転、停止を自在とし、肥料供給用ホッパーのスクリュー軸と、横架した回転軸とをベルトクラッチにより連結して、スクリュー軸の回転、停止を自在とする」という手段をとる。肥料供給用ホッパーのスクリューを回転させるための動力を取る方法として、機体後部に回転軸を横架して、エンジンの回転軸とベルトクラッチでつなぎ、この回転軸と左右の肥料供給用ホッパーのスクリュー軸をベルトクラッチでつなげれば、特別に動力を設けなくても、最も簡単にエンジンの回転からスクリューの回転を引き出すことが可能となり、その回転停止も自在にすることが出来る。
【0007】
請求項4記載の発明では、「茶畝を挟んだ2本の走行装置を門型枠でつなぎ、機体後部に左右の畝間を耕起する犂具を取付けた走行型茶園管理機において、機体後部に回転軸を横架し、エンジンにつながる回転軸とベルトクラッチにより連結して、回転、停止を自在とし、横架した回転軸の両端にクランクアームを設け、該クランクアームの回転により犂具の上下をさせる」という手段を用いる。機体後部に回転軸を横架し、その両端にクランクアームを設けて回転させれば、左右の畝間を耕起するために設けた犂具を動かして上下させることが出来る。又、その回転軸をエンジンにつながる回転軸とベルトクラッチで連結すれば、ベルトクラッチの入切で犂具の運転、停止が自在に出来る。機体が走行すれば、土中に差し込んだ犂具によって土が掘り起こされ、耕起作業が出来る。
【0008】
請求項5記載の発明では、「横架した回転軸をクランクアームが上方を向いたとき停止させる」という手段を用いる。犂具を土中に上下させて、耕起作業を行なうが、耕起作業を終わって移動する時は犂具を土中から引き上げておく必要がある。この場合、クランクアームが上を向いた状態で停止させればよい。この為、クランクアームが頂点の方向を向いたとき、ベルトクラッチが切れるようにして横架した回転軸を停止させるという方法を用いる。
【0009】
請求項6記載の発明では、「茶畝を挟んだ2本の走行装置を門型枠でつなぎ、機体後部に小型の肥料供給用ホッパーを設け、左右の畝間に少量ずつ肥料を散布すると共に、機体後部の左右に畝間を耕起する犂具を取付ける」という手段を用いる。畝間に散布する肥料は、散布されると同時に土中に混ぜ合わせた方が効果的である。この為、肥料散布装置と耕起装置を組合わせて設ければ、散布された肥料は耕起作業の犂具によって土中に混ぜ込まれる。この発明では、機体後部に横架した回転軸により、肥料供給用ホッパーのスクリューの回転と犂具の上下運動を同時にさせることが出来る。
【0010】
請求項7記載の発明では、「茶畝を挟んだ2本の走行装置を門型枠でつなぎ、一方の走行装置に作業者の運転席を設け、他方の走行装置上にエンジンを設け、機体後部に小型の肥料供給用ホッパーを設け、左右の畝間に少量ずつ肥料を散布する装置又は、機体後部の左右に畝間を耕起する犂具を取付けた走行型茶園管理機又は、肥料供給用ホッパーと畝間を耕起する犂具の双方を取付けた走行型茶園管理機において、門型枠下方に摘採装置を設け、摘採装置後方に摘採した茶葉を収容する茶袋を受ける茶袋受板を設け、摘採作業を可能とする」という手段を用いる。請求項1〜6記載の手段の肥料散布装置、耕起装置等は全て機体後部に取付けてある。従って、機体前部の門型枠の下に摘採装置を設け、摘採装置後方に摘採した茶葉を収容する茶袋を受ける茶袋受板を取付けた走行型茶葉摘採機は、機体後部に肥料散布装置、耕起装置を取付ければ、肥料散布作業、耕起作業以外のときは、摘採作業を行なうことも可能となる。この場合、茶袋受板の上に、肥料袋を積んでおくことが出来る。摘採作業をする時は、肥料供給用ホッパー及び耕起用の犂具は取り外しておく。
【0011】
【発明の実施の形態】
図面に基づいて、この発明の実施の形態を説明する。この実施例では、請求項7記載の発明の摘採装置を取付けたものを実施例としてあげる。図中の番号で()で示したものは、左右に同じものがついているもので、図示されていない右半分側に取り付けてあるものを示す。図1は、この発明の走行型茶園管理機の正面図である。図2は図1の側面図であり、摘採作業を行なう場合を示す。図3は図2において後部門型枠に肥料散布用ホッパーと耕起用犂具を取り付けた場合を示す側面図、図4は図3の後部立面図であり、後方から見て左半分を示しており、右半分は対称形のものが取付けてある。図5はエンジンの回転につながる回転軸と機体後部に横架した回転軸を連結するベルトクラッチの関係を示す側面図である。図6は平面図であり、機体後部に2ヶの肥料供給用ホッパーが設けてある。図7は機体後部に横架した回転軸と肥料供給用ホッパーのスクリュー軸を連結するベルトクラッチの関係を示す側面図、図8は肥料供給用ホッパーの開口部の調節機構を示す後立面図である。図9は犂具を上下させるクランクアームが真上を向いたとき停止させる機構を示す側面図、図10は図9を後方から見た立面図である。
【0012】
1、2は茶畝を挟んで畝間を走行する無端輸送帯で出来た走行装置である。左右の走行装置1、2はその前後で門型枠4、5で結ばれている。4は前部門型枠、5は後部門型枠である。前部門方枠4の下には、摘採装置6が取付けてある。摘採装置6は櫛状に吹出枝管7のついた送風ダクト8とバリカン状の刈刃9で構成される。送風ダクト8はファン10と接続しており、吹出枝管7の先から圧力風が噴出する。刈刃9の後方には茶袋11を取付け、摘採された茶葉を収容する。茶袋11を保持する為に茶袋受板12、補助板70が設けてある。走行装置1の上には運転席が設けてあり、作業者13が乗って運転する。走行装置2側にはエンジン14が設けてある。後部門型枠5の左右へ肥料供給用ホッパー15、16を取付ける。15、16は脱着が容易なように門型枠5へピン43で取付ける。肥料供給用ホッパー15、16の上部は開放されており、底面の半円筒部にはスクリュー17、18を横架する。スクリュー17、18は、コイル状に巻いたもので、コイル部分には中心軸がないものとする。半円筒底面の端には、開口部19、20が設けてある。
【0013】
図8で肥料供給用ホッパー15の開口部の詳細を示す。開口部19には開口面積を調節するためにシャッター21が取付けてあり、上下にスライドする。シャッター21はアーム22と連結棒23でつないであり、アーム22は支点24を中心として上下に回動する。アーム22を動かして、シャッター21の開度を調節し、ネジ25で固定する。右側の肥料供給用ホッパー16の開口部20に関しても、勝手違いになるが、同様にシャッターを設ける。開口部19、20の下には、ホッパーから取出された肥料を畝間に誘導するシュート26、27を取付ける。後部の門型枠5の外側には、回転軸28を横架する。
【0014】
図5によって、エンジン14と回転軸28の関係を説明する。29は補助回転軸であって、エンジンの出力軸30との間にはVベルト31が掛けてある。補助回転軸29と減速機32の入力軸との間にVベルト33が掛けてある。Vベルト33はアーム35の先に取付けられたテンションプーリー34で支えられている。又、このアーム35にはブレーキパッド36が取付けてあり、アーム35を下げてテンションをゆるめたとき、減速機32の入力軸のプーリ37を押えてブレーキが掛るようにしてある。減速機32の出力軸38と回転軸28にはスプロケット74、75が取付けてあり、チェン39が掛けてある。アーム35を上に引っ張り上げると、ブレーキパッド36はプーリ37から外れ、Vベルト33を張るので、補助回転軸29の回転が減速機32へ伝えられ、回転軸28を回転する。
【0015】
図7により、回転軸28の回転をスクリュー17に伝える機構について説明する。肥料供給用ホッパー15のスクリュー17の回転軸にはプーリ40が取付けてあり、回転軸28のプーリ41との間にVベルト42が掛けてある。ホッパー15の上部はピン43で支えられ、下部はリンク棒44、45で機体の支柱とつながっている。リンク棒45には操作棒46が取付けてあり、操作棒46を引き上げると、リンク棒44、45は44’、45’の位置に折れ曲がり、ホッパー15の底部は柱側へ引き寄せられ、Vベルト42がたるむ。操作棒46を下に押せば、Vベルト42が引っ張られ、回転軸28の回転がプーリ40に伝えられ、スクリュー17が回転する。回転軸28の両端には、クランクアーム47、48がついている。走行装置1、2の後には耕起用の犂具49、50が設けてある。犂具49、50はピン51、52を支点として、アーム53、54の先に取付けてある。アーム53、54はピン55、56を介して、ホーク57、58で支えられており、ホーク57、58はロッド59、60によりクランクアーム47、48と連結してある。ロッド59、60にはバネ61、62が入れてあり、犂具49、50に無理な力が掛ったときは、バネ61、62が縮んで逃げることが出来る。クランクアーム47、48の回転により、犂具49、50はピン51、52を支点として、上下に運動する。機体を走行させると、犂具49、50が土を耕起させる作用が生じる。
【0016】
図9、図10により、クランクアーム47、48を真上に向いた状態で止める機構について説明する。63は回転軸28を回転、停止させるためのレバーである。ピン64を支点として、90°回動する。レバー63の中間にピン65を介してコントロールワイヤー66がつなげてある。コントロールワイヤー66の他端は、テンションプーリー34、ブレーキパッド36が取付けてあるアーム35につなげてある。レバー63を63’の位置に上げると、コントロールワイヤー66がゆるみ、アーム35を下げるので、Vベルト33がゆるみ、ブレーキパッド36がプーリ37を押さえ、プーリ37にブレーキが掛り、回転軸28は停止する。レバー63を水平位置まで回すと、コントロールワイヤー66が引っ張られて、アーム35を上に上げ、ブレーキパッド36がプーリ37から離れ、テンションプーリー34がVベルト33を押し上げて張るので、補助回転軸29の回転が回転軸28に伝わり、回転する。67は停止具であって、ピン68により門型枠5の支柱に取付けてあり、ピン68を支点として回動自在とする。クランクアーム47が回転中は、停止具67はピン69に引っ掛けておき、クランクアーム47に当らないようにしておく。停止具67をピン69から外し、回転軸28の方へ下げると、クランクアーム47が回転して、上へ向くと停止具67を上へ押し上げる。その結果、停止具67の上部がレバー63を上方へ押し上げ、レバー63は63’の位置まで回動する。コントロールワイヤー66は66’の位置になってゆるめられる。コントロールワイヤー66を介してアーム35が下り、Vベルト33がゆるみ、回転軸28はクランクアーム47が上を向いた状態で停止する。
【0017】
摘採作業を行なう場合について、図2で説明する。摘採作業のときは、機体後部に取付けた肥料散布装置、耕起装置を全て取外す。茶袋受板12の後に補助板70を取付けて、茶袋11を摘採装置に取付け、摘採作業を行う。次に、肥料散布と耕起の作業について説明する。この二つは、まず、摘採作業用の補助板70を取外し、機体後部に肥料散布装置一式、耕起装置一式を取付け、図5で示すような回転軸28にエンジンの回転を伝えるVベルト33を使ったベルトクラッチ装置一式を取付ける。次いで、肥料供給用ホッパー15、16に肥料を投入し、ホッパーの開口部のシャッター21を調節して、肥料の取出量を合わせる。走行装置1、2を畝間にあわせ、ゆっくり走行させる。レバー63を倒すと回転軸28が廻り始め、犂具49、50が上下し、耕起作業が始まる。次いで、操作棒46、47を押し下げると、スクリュー17、18が回転し、開口部19、20から肥料が少しずつ取出され、シュート26、27を通って、畝間に散布され、犂具49、50で土中に犂込まれる。茶畝の端まで行ったら、停止具67をピン69から外すと、クランク28が頂点に向いたところで、レバー63が押し上げられ、犂具49、50が引き上げられた状態で停止する。この状態で、次の畝間へ走行し次の作業へ入る。作業の途中でホッパー内の肥料がなくなったら、茶袋受板12の上に乗せてある肥料袋71を開いて、補給する。
【0018】
この実施例では、主として摘採作業を行なう乗用型茶葉摘採機に耕起装置、肥料散布装置を取り付けたものを示しているが、摘採装置のない耕起作業又は、肥料散布作業のみの専用機、及び耕起、肥料散布作業の複合専用機とすれば、単純化され、軽量で、更に安価なものを提供できる。
【0019】
【発明の効果】
乗用型肥料散布機としては、重量の重い大型機が一部で用いられている。一般的には、小形の手押し車にエンジンを取付けたものを、畝間に沿って作業者が歩行しながらついていくタイプのものが用いられている。この場合、肥料を入れるホッパーも小型であり、長い茶畝では途中でホッパーが空になる場合もある。この場合、作業者は肥料袋を担いで茶畝の中を歩いて持っていき、補給せねばならない。又、肥料散布と耕起作業を同時に行うことが出来ないので、肥料散布の作業が終わった後で、もう一度エンジンのついた歩行式の耕起機を持ち出して、同じ畝に沿って耕起作業をしなければならない。
【0020】
この発明の走行型茶園管理機を用いれば、作業者は茶畝に沿って歩かなくてもよい。又、肥料袋を機体に積むことが出来るので、肥料袋を作業者が運ぶ必要はない。又、肥料散布と耕起作業を同時に行うことが出来るので、能率的である。又、一回の走行で2本の畝間を同時に作業できるので、更に、能率的である。一般的に使用されている小型の乗用型茶葉摘採機に簡単な肥料散布装置と耕起装置を取付けるだけで摘採作業の他に肥料散布と耕起作業を行なうことができる。摘採時期と肥料散布、耕起作業の時期は同じではないので、機械の有効利用を計ることが出来、経済効果が期待出来る。

[0003]
[Problems to be solved by the invention]
Japanese Patent Application Laid-Open No. 2002-101729 discloses that a fertilizer spraying operation and a plowing operation are performed as a part of a multipurpose operation in a tea plantation, but a detailed mechanism for performing the operation is not shown. . SUMMARY OF THE INVENTION It is an object of the present invention to provide a detailed mechanism for performing a fertilizer spraying operation and a plowing operation by a traveling tea garden management machine. Furthermore, a multipurpose work vehicle that performs various kinds of work as disclosed in JP-A-2002-101729 has not been put to practical use at present. Accordingly, an object of the present invention is to make it possible to perform a fertilizer spraying operation and a plowing operation by using a riding type tea leaf picking machine which is currently most frequently used.
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, in the invention according to claim 1, “two traveling devices sandwiching a tea ridge are connected by a gate frame, a small fertilizer supply hopper is provided at a rear portion of the fuselage, and a left and right ridge is provided. In a traveling tea garden management machine equipped with a device for spraying fertilizer little by little, the upper part of the hopper for fertilizer supply can be opened as a rectangular box, the upper part can be opened, the lower part is a semi-cylindrical type, and the screw shaft along the cylindrical bottom , The opening of which the opening area can be adjusted is provided at the end of the bottom surface, and the fertilizer is discharged from the opening by the rotation of the screw. " The traveling-type tea garden management machine of the present invention is intended to be used in a small-scale tea garden. In Japanese Patent Application Laid-Open No. 2002-101729, a large hopper for spreading fertilizer, whose lower surface is made of a belt conveyor, is provided at the center of the machine body, automatically diverted to the left and right, and further provided with a fertilizer spraying machine. In this invention, a large fertilizer hopper is not provided, the fertilizer is stacked in the center of the fuselage in a state of being kept in the fertilizer bag, and a box-shaped upper surface can be opened at the rear of the fuselage, and the lower surface has a semi-cylindrical shape, A small fertilizer supply hopper with a horizontal screw shaft is provided. When the fertilizer supply hopper is emptied, the stored fertilizer bags are opened and manually put into the fertilizer supply hopper. The fertilizer contained in the fertilizer supply hopper is moved toward the left and right side walls of the hopper by the rotation of a screw suspended on the bottom surface. The screws are twisted in opposite directions on the left and right sides of the hopper, are respectively moved in the directions along the left and right ridges, and are taken out from the openings provided therein. By adjusting the area of the opening, the amount of extraction can be adjusted.
[0005]
The invention described in claim 2 uses a means of "dividing the fertilizer supply hopper into two parts, one for the left furrow and the other for the right furrow, so as to be detachable from the machine body." The traveling tea garden management machine of the present invention is made small and lightweight, and is premised on being carried by a small truck. Therefore, if the fertilizer supply hopper at the rear of the machine is detachable, it can be transported without protruding from the truck bed by removing it during transportation.
[0006]
According to the third aspect of the invention, "a rotary shaft is horizontally mounted on the rear part of the fuselage, and the rotary shaft and the rotary shaft connected to the engine are connected by a belt clutch so that rotation and stop can be freely performed. And the horizontal rotating shaft are connected by a belt clutch so that the screw shaft can be freely rotated and stopped. " As a method to take power for rotating the screw of the fertilizer supply hopper, a rotating shaft is laid across the rear of the fuselage, connected with the engine rotation shaft by a belt clutch, and this rotation shaft and the left and right fertilizer supply hopper screws If the shaft is connected by a belt clutch, the rotation of the screw can be extracted from the rotation of the engine most easily without special power, and the rotation can be stopped freely.
[0007]
In the invention according to claim 4, "a traveling type tea garden management machine in which two traveling devices sandwiching a tea ridge are connected by a portal frame and a plow for plowing left and right ridges is attached to a rear portion of the aircraft. The rotation shaft is mounted horizontally, and the rotation shaft connected to the engine is connected to the rotation shaft by a belt clutch to enable rotation and stop. Crank arms are provided at both ends of the horizontally mounted rotation shaft. Means to move up and down. " If a rotating shaft is mounted horizontally on the rear part of the fuselage and crank arms are provided at both ends of the rotating shaft, the plows provided for plowing the left and right furrows can be moved up and down. If the rotating shaft is connected to the rotating shaft connected to the engine by a belt clutch, the operation and stop of the plow can be freely performed by turning on and off the belt clutch. When the aircraft travels, the soil can be dug up by the plows inserted into the soil, and tilling work can be performed.
[0008]
The invention described in claim 5 uses a means of "stopping the horizontally-rotated rotating shaft when the crank arm faces upward". The plow is raised and lowered in the soil to perform the plowing work, but when moving after the plowing work, it is necessary to raise the plow from the soil. In this case, the operation may be stopped with the crank arm facing upward. For this reason, a method is used in which, when the crank arm faces the direction of the top, the belt clutch is disengaged and the rotating shaft suspended laterally is stopped.
[0009]
In the invention according to claim 6, "the two traveling devices sandwiching the tea ridges are connected by a portal frame, a small fertilizer supply hopper is provided at the rear of the fuselage, and the fertilizer is sprayed little by little between the left and right ridges, Attach plows to plow furrows on the left and right sides of the rear of the fuselage.

【The invention's effect】
Some heavy-duty heavy-duty machines are used as riding-type fertilizer spreaders. In general, a type in which an engine is mounted on a small wheelbarrow and a worker follows along a ridge while walking is used. In this case, the hopper for storing the fertilizer is also small, and the hopper may become empty in the middle of a long tea ridge. In this case, the worker has to carry the fertilizer bag by walking along the tea ridge and replenishing. Also, since fertilizer application and plowing work cannot be performed at the same time, after finishing the fertilizer application work, take out the walk-type tiller with the engine again and plow along the same ridge. Have to do.
[0020]
By using the traveling tea garden management machine of the present invention, the worker does not have to walk along the tea ridge. Also, since the fertilizer bags can be loaded on the body, there is no need for the operator to carry the fertilizer bags. Further, since the fertilizer spraying and the plowing work can be performed at the same time, it is efficient. Further, since two ridges can be simultaneously worked in one run, the efficiency is further improved. By simply attaching a simple fertilizer spraying device and a tillage device to a small, generally used riding type tea picker, it is possible to perform fertilizer spraying and plowing work in addition to the picking operation. Since the harvesting time is not the same as the time of fertilizer application and tillage work, the effective use of the machine can be measured and the economic effect can be expected.
