【産業上の利用分野】
本発明は草刈機の改良に関する。
【0002】
【従来の技術】
稲作の労働軽減の一策として、畦の草刈りを人力から機械力に置き換える試みがなされ、例えば特開平6−276825号公報「草刈機及び角度調整装置及び揺動制御装置」があり、その公報の図1及び図5によれば、フレームFにカッター基台2(第1ハウジングに相当)を取付け、このカッター基台2に可変カッター基台3(第2ハウジングに相当)をヒンジ29で連結した草刈機であって、カッター基台2に畦の上面を刈る回転刃43を収納し、可変カッター基台3に畦の斜面を刈る回転刃43aを収納した構成である。可変カッター基台3の前部が草を導入するために開放され、更に、前部にガイド車輪31(補助輪に相当)を備えている。
【0003】
ところで、このような草刈機の第2ハウジングは、図6に示すような構成にして草の導入を容易にすることが多い。
図6(a)〜(c)は従来の草刈機の第2ハウジングの前部の説明図である。図6(a)に示すように畦101には、太く長い茎に生い茂った草(雑草)102…が密生していることが多い。このような草102…は地面からほぼ垂直に生え、根が強く茎も丈夫である。
このため、草102…を草刈機で刈る場合に、第2ハウジング103の天井板が平坦であると、それの前端103aで草102…を押しても丈夫なので簡単には傾かない。
従って、第2ハウジング103の前端103aから斜面刃104までの距離が長いと、草102…は第2ハウジング103内に入り難いので、斜面刃104に当たらず刈り残しが出る恐れがある。
【0004】
そこで、このような問題点を解消するために、図6(b),(c)に示すように、第2ハウジング103の前端103aに傾斜状の草導入部105を延出することが好ましい。
これによれば、草102…は草導入部105に倣って傾きながら第2ハウジング103内に導入され、斜面刃104できれいに刈り取られる。
【0005】
【発明が解決しようとする課題】
しかしながら、上記図6(b),(c)の構成では、第2ハウジング103の前部にアーム106で補助輪107を取付けているので、アーム106と草導入部105との間の隙間108に草102…が噛み込んで、草刈機の進行を阻害する心配がある。草102…は隙間108に密集して噛み込み、しかも地面に十分に根を張っているので抵抗が強く、草刈機の進行を妨げる。
本発明の目的は、補助輪を取付けるアームと草導入部との間の隙間への草の侵入を防止することにある。
【0006】
【課題を解決するための手段】
上記目的を達成するために本発明は、車輪を備えた車体フレームに第1ハウジングを取付け、第1ハウジングに第2カッタハウジングをヒンジ連結し、前記第2ハウジングの前部から前方へ斜めに上った形状の草導入部を延出し、この草導入部の側方に隙間を有して且つ草導入部に沿って第2ハウジングからアームを延出し、このアームに補助輪を取付け、第1ハウジング内の平面刃で畦の上面を刈り、第2ハウジング内の斜面刃で畦の斜面を刈る形式の草刈機において、前記草導入部とアームとの間の前記隙間への草の侵入を防止する侵入防止部材を、草導入部の前端部に一体に形成するとともに前端部からアームに向かって延出して、前記隙間の前側を塞いだことを特徴とする。
【0007】
【作用】
草導入部とアームとの間の隙間は、侵入防止部材で塞がれている。このため、草は侵入防止部材によって隙間への侵入が阻止される。
【0008】
【実施例】
本発明の実施例を添付図に基づいて以下に説明する。なお、「前」、「後」、「左」、「右」、「上」、「下」は草刈機の作業者から見た方向に従う。また、図面は符号の向きに見るものとする。
図1は本発明に係る草刈機の平面図であり、草刈機1は、パイプ状の車体フレーム2の前部に前輪3、後部に後輪4を備え、前記車体フレーム2に、より大径の揺動管5を嵌合し、この揺動管5にエンジン7を載置するとともにカッタハウジング10を吊り下げ、カッタハウジング10内部に平面刃21と斜面刃22とを前後及び左右に離間して配置した二面刈り草刈機の構成である。
【0009】
カッタハウジング10は、車体フレーム2に取付けられた固定側ハウジングとしての第1ハウジング11と揺動側ハウジングとしての第2ハウジング12とをヒンジ13にて連結したものであり、第1ハウジング11は平面刃21を収納し、第2ハウジング12は斜面刃22を収納する。14はヒンジ13を通る揺動軸線である。
すなわち、草刈機1は後輪4の輪幅中心を通る車体フレーム2の走行方向軸心から一方(この実施例では左側)に平面刃21及び斜面刃22をオフセットし、同方向に前輪3もオフセットし、他方(この実施例では右側)にエンジン7をオフセットしたものである。平面刃21は走行方向軸心からわずかにオフセットしている。
【0010】
この場合、前輪3は草刈機1を走行する際の操縦の目安となるガイド車輪であって細幅タイヤからなり、後輪4は草刈機1を自走するための走行車輪であって広幅タイヤからなる。
更に、草刈機1は後輪4側を前輪3側よりも重く設定され、例えば、草刈機1の重量配分は、前輪3で受ける重量と後輪4で受ける重量との比率を約1:4に設定される。
【0011】
前輪3は、車体フレーム2の前部から延出した前輪用アーム23に取付けられる。また、第2ハウジング12の左側前部から補助輪用アーム24が延出され、補助輪用アーム24の前部に第2ハウジング12の高さを規定するための補助輪25が取付けられる。
【0012】
エンジン7は出力軸7aが下向きであり、ベルト伝動機構30を介して前記平面刃21及び斜面刃22を回動するものである。
ベルト伝動機構30は上下2段に張られた第1ベルト31、第2ベルト32及びプーリ類からなり、第1ベルト31で平面刃21を駆動し、第2ベルト32で斜面刃22を駆動するものである。
すなわち、第1ベルト31は、エンジン7の出力軸7aに取付けられた第1プーリ33と、平面刃軸21aを駆動するための第2プーリ34とに巻回されている。
【0013】
42は第1ハウジング11に係止された揺動レバーであり、この揺動レバー42の一端にテンショナーロール43、他端にブレーキシュー44を形成し、作業者が図示せぬ操作レバー及びワイヤで揺動レバー42を図反時計方向へ揺動すれば、第1ベルト31は緊張して、第1プーリ33の動力を第2プーリ34に伝達し、平面刃軸21aを駆動する構成となっている。逆に、揺動レバー42を図時計方向へ揺動すれば、第1ベルト31は弛み、動力の伝達が弱まり、ブレーキシュー42で第1ベルト31を制動することができる。
以上の要領で、エンジン運転中並びに走行中に、任意に平面刃21の運転/停止をなせる。
【0014】
第2ベルト32は、第2プーリ34の下方に一体形成されたアイドラープーリ35(以下「第3プーリ35」と言う)、斜面刃軸22aを駆動するための第4プーリ36、揺動軸線14の近傍に概ね前後1列に配列された3つのアイドラープーリ37〜39(以下「第5・第6・第7プーリ37〜39」と言う)、第5プーリ37の下方に一体形成されたアイドラープーリ41(以下「第8プーリ41」と言う)に巻回されている。
配置的には、後側の第5プーリ37(第8プーリ41を含む)を第1ハウジング11に軸支し、前側の傾斜した第6プーリ38及び中央の第7プーリ39を第2ハウジング12に軸支している。従って、第2ベルト32は第3プーリ35・第5プーリ37・第6プーリ38・第4プーリ36・第7プーリ39・第8プーリ41・第3プーリ35のループで巻回される。
【0015】
図2は本発明に係る草刈機の側面図(要部)であり、車体フレーム2に揺動管5が取付けられ、この揺動管5にマウントプレート6を介してエンジン7がマウントされ、一方、揺動管5にハンガブラケット8,8を介して第1ハウジング11が吊り下げられていることを示す。
エンジン7は上記2つの刈刃(平面刃21及び斜面刃22)の他に、ユニバーサル軸26を介して無段変速機27を駆動し、この無段変速機27でチェーン28を介して後輪4を駆動するものである。
【0016】
前輪用アーム23はピン51で車体フレーム2側に取付けられているとともに、差込みピン52を差し替えることにより取付け角を変更できる機構となっている。53…(…は複数を示す。以下同じ。)はピン孔であり、54はプレートである。
同様に、補助輪用アーム24はピン55で第2ハウジング12側に取付けられているとともに、差込みピン56を差し替えることにより取付け角を変更できる機構となっている。57はプレートである。
また、ハンドル61は車体フレーム2の後部にピン62で揺動可能に取付けられ、差込みピン63を差し替えることにより取付け角を変更できる機構となっている。64…はピン孔であり、65はサポートである。
【0017】
なお、上記揺動管5を廃止し、車体フレーム2にブラケットを介して第1ハウジング11を直接的に取付けてもよいが、本実施例では第1ハウジング11もある程度揺動可能にした。また、カッタハウジング10は車体フレーム2に取付けられる構成であればよく、吊り下げる構成に限らず、例えば載置するものでもよい。
【0018】
図3は本発明に係る草刈機の揺動姿勢を示す図(正面視)であり、第1ハウジング11にヒンジ13を介して第2ハウジング12が揺動自在に連結されていることを示す。
なお、67は前輪3を跨ぐパイプ状の前輪ガード部材であり、第1ハウジング11の前端に取付けられたブラケット68にボルト固定される。
【0019】
図4は本発明に係る第2ハウジングの前部の平面図であり、第2ハウジング12の前部左側部に草導入部15を延出し、この草導入部15に沿って第2ハウジング12からアーム(補助輪用アーム)24を延出したことを示す。
草導入部15は図2に示すように、前方(この図の左側)へ斜めに上った形状のものである。このため、草Pの先端部分が草導入部15に倣って傾きながら第2ハウジング12内に導入されるので、草Pは斜面刃22できれいに刈り取られる。
【0020】
ところで、第2ハウジング12の上部に取付けられた補助輪用アーム24は、上下方向(この図の表裏方向)の取付角が調整可能な構成である。このように、補助輪用アーム24が揺動可能であるためには、草導入部15と補助輪用アーム24との間には必然的に隙間Sを要し、この隙間Sに草Pが侵入し易い。隙間Sに侵入する草Pは畦から立上がって生えているので、草Pの侵入を防止するには、地面と概ね水平(第2ハウジング12の天井板と概ね平行)にした部材で隙間Sの前端を塞げばよい。
そこで、草導入部15の前端部には、隙間Sの前側を塞いで隙間Sへの草Pの侵入を防止するための侵入防止部材16を一体に形成する。
【0021】
図5は図4の5−5線拡大断面図であり、侵入防止部材16は草導入部15の前端部から補助輪用アーム24に向って延出しており、少なくとも補助輪用アーム24の一部にオーバーラップし、好ましくは補助輪用アーム24の軸心まで若しくはそれ以上オーバーラップする。
なお、草導入部15の左側面(補助輪用アーム24と反対側)は、第2ハウジング12(図4参照)から延出した側壁15aで覆われている。
【0022】
以上に述べた草刈機の作用を図2及び図3に基づき説明する。
図2に示す姿勢の草刈機1は、斜面刃22が平面刃21と平行(面一)であるところの非揺動姿勢をしており、農道走行及び広い平坦面の草刈に適している。この際、図示しないチェーン等を使用して第2ハウジング12を持上げることにより、補助輪25を地面から浮せることもできる。
図3に示す姿勢の草刈機1は、畦70の上面71に平面刃21が平行とされ、斜面72に倣って第2ハウジング12並びに斜面刃22が傾斜した姿勢であり、この姿勢で、平面刃21で畦70の上面71の草を刈り、斜面刃22で斜面72の草を刈る。
【0023】
次に、侵入防止部材16の作用を図4に基づき説明する。
草導入部15の前部に侵入防止部材16を設けているので、侵入防止部材16で隙間Sの前側が塞がれるため、草刈機を前進させても隙間Sに草Pが侵入しない。このため、隙間Sに草Pが噛み込んで、草刈機の進行を阻害する心配がない。また、侵入防止部材16は草導入部15の前部に設けるだけの簡単な構造でよい。
【0024】
なお、上記実施例において、侵入防止部材16は草導入部15と補助輪用アーム24との間の隙間Sへの草Pの侵入を防止するものであり、補助輪用アーム24に設ける構成でもよい。
また、侵入防止部材16は草導入部15や補助輪用アーム24と一体に形成する構成の他に、例えば棒材等の別部材を固着した構成にしてもよい。
【0025】
【発明の効果】
以上に述べた通り本発明は、第2ハウジングの前部から前方へ斜めに上った形状の草導入部を延出し、この草導入部の側方に隙間を有して且つ草導入部に沿って第2ハウジングからアームを延出し、このアームに補助輪を取付け、草導入部とアームとの間の隙間への草の侵入を防止する侵入防止部材を、草導入部の前端部に一体に形成するとともに前端部からアームに向かって延出して、隙間の前側を塞いだことにより、草導入部とアームとの間の隙間への草の侵入を容易に防止できるので、草刈機の円滑な走行が図れる。

[Industrial applications]
The present invention relates to an improvement of a mower.
[0002]
[Prior art]
As a measure to reduce the labor required for rice cultivation, attempts have been made to replace mowing of ridges with human power instead of mechanical power. According to FIGS. 1 and 5, the cutter base 2 (corresponding to the first housing) is mounted on the frame F, and the variable cutter base 3 (corresponding to the second housing) is connected to the cutter base 2 with the hinge 29. The mowing machine has a configuration in which a rotary blade 43 for cutting the upper surface of a ridge is stored in a cutter base 2 and a rotary blade 43a for cutting a slope of a ridge is stored in a variable cutter base 3. The front portion of the variable cutter base 3 is opened for introducing grass, and further has a guide wheel 31 (corresponding to an auxiliary wheel) at the front portion.
[0003]
By the way, the second housing of such a mower is often configured as shown in FIG. 6 to facilitate introduction of grass.
FIGS. 6A to 6C are explanatory views of a front portion of a second housing of a conventional mower. As shown in FIG. 6A, grasses (weeds) 102. These grasses 102 grow almost vertically from the ground, and have strong roots and strong stems.
For this reason, when the grass 102 is cut by a mower, if the ceiling plate of the second housing 103 is flat, the grass 102 is not easily tilted even if the grass 102 is pushed with its front end 103a.
Therefore, if the distance from the front end 103a of the second housing 103 to the slope blade 104 is long, the grass 102 is unlikely to enter the second housing 103, and there is a possibility that uncut leaves will not come into contact with the slope blade 104.
[0004]
Therefore, in order to solve such a problem, as shown in FIGS. 6B and 6C, it is preferable to extend the inclined grass introduction portion 105 to the front end 103 a of the second housing 103.
According to this, the grass 102... Is introduced into the second housing 103 while being inclined in accordance with the grass introduction section 105, and the grass 102 is neatly cut off by the slope blade 104.
[0005]
[Problems to be solved by the invention]
However, in the configuration shown in FIGS. 6B and 6C, since the auxiliary wheel 107 is attached to the front portion of the second housing 103 by the arm 106, the gap 108 between the arm 106 and the grass introduction portion 105 is not provided. There is a concern that the grass 102 may bite and hinder the progress of the mower. The grass 102 densely bites into the gap 108 and is sufficiently rooted on the ground, so that resistance is strong and hinders the progress of the mower.
An object of the present invention is to prevent grass from entering a gap between an arm for attaching an auxiliary wheel and a grass introduction portion.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a vehicle body frame equipped with wheels, wherein a first housing is mounted, a second cutter housing is hingedly connected to the first housing, and a front side of the second housing is inclined obliquely upward from the front. An arm extending from the second housing along the grass introduction portion with a gap beside the grass introduction portion, and an auxiliary wheel attached to the arm. cutting the top surface of the ridge in the plane blade in the housing, in the form of mower mow slope ridge slopes blade in the second housing, prevents the grass from entering the gap between the grass inlet portion and the arm The intrusion prevention member is formed integrally with the front end of the grass introduction portion and extends from the front end toward the arm to close the front side of the gap .
[0007]
[Action]
The gap between the grass introduction part and the arm is closed by an intrusion prevention member. Therefore, grass is prevented from entering the gap by the intrusion prevention member.
[0008]
【Example】
An embodiment of the present invention will be described below with reference to the accompanying drawings. Note that “front”, “rear”, “left”, “right”, “up”, and “down” follow directions viewed from a mower operator. Also, the drawings should be viewed in the direction of reference numerals.
FIG. 1 is a plan view of a mower according to the present invention. The mower 1 has a front wheel 3 at a front part and a rear wheel 4 at a rear part of a pipe-shaped body frame 2. The swinging tube 5 is fitted, the engine 7 is mounted on the swinging tube 5 and the cutter housing 10 is suspended, and the plane blade 21 and the inclined blade 22 are separated in the cutter housing 10 in the front-back and left-right directions. This is a configuration of a two-side mowing mower arranged in a vertical direction.
[0009]
The cutter housing 10 is formed by connecting a first housing 11 as a fixed housing attached to the vehicle body frame 2 and a second housing 12 as a swinging housing by a hinge 13, and the first housing 11 is flat. The second housing 12 houses the bevel blade 22. Reference numeral 14 denotes a swing axis passing through the hinge 13.
That is, the mower 1 offsets the plane blade 21 and the slope blade 22 to one side (left side in this embodiment) from the running direction axis of the body frame 2 passing through the center of the width of the rear wheel 4, and the front wheel 3 also moves in the same direction. The engine 7 is offset to the other (the right side in this embodiment). The plane blade 21 is slightly offset from the axis in the traveling direction.
[0010]
In this case, the front wheel 3 is a guide wheel serving as a guide for operation when the mower 1 is driven, and is composed of a narrow tire. The rear wheel 4 is a traveling wheel for self-propelling the mower 1 and is a wide tire. Consists of
Further, the mower 1 is set so that the rear wheel 4 side is heavier than the front wheel 3 side. For example, the weight distribution of the mower 1 is such that the ratio of the weight received by the front wheel 3 to the weight received by the rear wheel 4 is about 1: 4. Is set to

Reference numeral 42 denotes a swinging lever locked to the first housing 11. The swinging lever 42 has a tensioner roll 43 formed at one end and a brake shoe 44 formed at the other end. When the swing lever 42 swings counterclockwise in the figure, the first belt 31 is tightened, transmitting the power of the first pulley 33 to the second pulley 34, and driving the flat blade shaft 21a. I have. Conversely, if the swing lever 42 is swung clockwise in the figure, the first belt 31 is slackened, the power transmission is weakened, and the brake shoe 42 can brake the first belt 31.
In the above manner, the operation / stop of the plane blade 21 can be arbitrarily performed during the operation of the engine and the traveling.
[0014]
The second belt 32 includes an idler pulley 35 (hereinafter, referred to as a “third pulley 35”) integrally formed below the second pulley 34, a fourth pulley 36 for driving the inclined blade shaft 22 a, and the swing axis 14. , Three idler pulleys 37 to 39 (hereinafter, referred to as “fifth, sixth, and seventh pulleys 37 to 39”) arranged substantially in a row in front and rear, and an idler integrally formed below the fifth pulley 37. It is wound around a pulley 41 (hereinafter referred to as an “eighth pulley 41”).
In terms of arrangement, the rear fifth pulley 37 (including the eighth pulley 41) is pivotally supported by the first housing 11, and the front inclined sixth pulley 38 and the central seventh pulley 39 are connected to the second housing 12 It is pivoted. Accordingly, the second belt 32 is wound around the third pulley 35, the fifth pulley 37, the sixth pulley 38, the fourth pulley 36, the seventh pulley 39, the eighth pulley 41, and the third pulley 35.
[0015]

Shows that the first housing 11 is suspended from the swing tube 5 via the hanger brackets 8, 8.
The engine 7 drives a continuously variable transmission 27 via a universal shaft 26 in addition to the two cutting blades (the plane blade 21 and the sloped blade 22). 4 is driven.
[0016]
The front wheel arm 23 is mounted on the vehicle body frame 2 side with a pin 51 and has a mechanism that can change the mounting angle by replacing the insertion pin 52. Numerals 53 (... indicate plural numbers, the same applies hereinafter) are pin holes, and 54 is a plate.
Similarly, the auxiliary wheel arm 24 is mounted on the second housing 12 side with a pin 55, and has a mechanism that can change the mounting angle by replacing the insertion pin 56. 57 is a plate.
The handle 61 is swingably attached to the rear portion of the vehicle body frame 2 with a pin 62, and has a mechanism capable of changing an attachment angle by replacing the insertion pin 63. 64 are pin holes, and 65 is a support.
[0017]
Note that the swinging tube 5 may be eliminated and the first housing 11 may be directly attached to the vehicle body frame 2 via a bracket, but in the present embodiment, the first housing 11 is also allowed to swing to some extent. Further, the cutter housing 10 may have any configuration as long as it can be attached to the vehicle body frame 2, and is not limited to a configuration in which the cutter housing 10 is hung, and may be, for example, mounted.
[0018]
FIG. 3 is a view (a front view) showing a swing posture of the mower according to the present invention, and shows that the second housing 12 is swingably connected to the first housing 11 via the hinge 13.
Reference numeral 67 denotes a pipe-shaped front wheel guard member that straddles the front wheel 3 and is bolted to a bracket 68 attached to the front end of the first housing 11.
[0019]
FIG. 4 is a plan view of the front part of the second housing according to the present invention. The grass introduction part 15 extends to the front left part of the second housing 12 and extends from the second housing 12 along the grass introduction part 15. This shows that the arm (arm for auxiliary wheel) 24 has been extended.
As shown in FIG. 2, the grass introduction section 15 has a shape that is inclined obliquely forward (to the left in this figure). For this reason, the tip of the grass P is introduced into the second housing 12 while being inclined following the grass introduction part 15, so that the grass P is neatly cut by the slope blade 22.
[0020]
By the way, the auxiliary wheel arm 24 mounted on the upper part of the second housing 12 has a configuration in which the mounting angle in the vertical direction (the front and back direction in this figure) can be adjusted. Thus, in order for the auxiliary wheel arm 24 to be able to swing, a gap S is inevitably required between the grass introduction portion 15 and the auxiliary wheel arm 24, and the grass P is in the gap S. Easy to invade. Since the grass P penetrating into the gap S grows up from the ridge, in order to prevent the grass P from entering, the gap S is formed by a member which is substantially horizontal to the ground (substantially parallel to the ceiling plate of the second housing 12). You just need to close the front end of the.
Therefore, an intrusion prevention member 16 for closing the front side of the gap S and preventing the grass P from entering the gap S is integrally formed at the front end of the grass introduction section 15.
