地面に沿って回転するブレード12を軸支して上方から覆うブレードハウジング２が、左右一対の前輪６，６および後輪７，７によって走行自在に支持されている。
本明細書中では、芝刈機１の前進方向を向いた状態を基準にして前後左右を決めることとする。 1 is an overall perspective view of the lawn mower 1, FIG. 2 is a side view of the lawn mower body, FIG. 3 is a plan view thereof, and FIG. 4 is a rear view thereof.
A blade housing 2 that pivotally supports a blade 12 that rotates along the ground and covers it from above is supported by a pair of left and right front wheels 6 and 6 and rear wheels 7 and 7 so as to be able to run.
In the present specification, the front, rear, left and right are determined based on the state in which the lawn mower 1 faces the forward direction.

ブレードハウジング２は、４隅が前輪６，６と後輪７，７の４輪を軸支する軸受部２ｆ、２ｆ、２ｒ、２ｒをなし、軸受部２ｆ、２ｆ、２ｒ、２ｒに囲まれた中央部２ｃの下部が偏平椀状をなしてブレード12を覆うブレード収容部２ｂが形成され、中央部２ｃは後半が後方へいくに従い上方に膨出し、さらに後方に連続して上方に膨出した膨出部２ｅが形成されている。   The blade housing 2 has bearing portions 2f, 2f, 2r, and 2r that pivotally support the four wheels of the front wheels 6 and 6 and the rear wheels 7 and 7, and is surrounded by the bearing portions 2f, 2f, 2r, and 2r. The lower portion of the central portion 2c is formed in a flat bowl shape to form a blade accommodating portion 2b that covers the blade 12, and the central portion 2c bulges upward as the latter half moves backward, and further bulges upward continuously in the rear. A bulging portion 2e is formed.

このブレードハウジング２の中央部２ｃに、内燃機関10がクランク軸11を鉛直に指向させて搭載されている。
内燃機関10は、シリンダ10cyを前方に向け、クランクケース10ｃからクランク軸11を下方に突出している。 An internal combustion engine 10 is mounted on the central portion 2c of the blade housing 2 with the crankshaft 11 oriented vertically.
The internal combustion engine 10 has a cylinder 10cy facing forward and a crankshaft 11 protruding downward from a crankcase 10c.

クランク軸11とブレード12との間に電磁クラッチ20が介装されている。
したがって、内燃機関10の駆動が電磁クラッチ20の接続を介してブレード12を回転して芝を刈ることができる。 An electromagnetic clutch 20 is interposed between the crankshaft 11 and the blade 12.
Therefore, the driving of the internal combustion engine 10 can rotate the blade 12 via the connection of the electromagnetic clutch 20 to mow the lawn.

ブレードハウジング２における中央部２ｃの右側部から後半の膨出部２ｅに亘って斜めに鉛直仕切板３（図３参照）によってブレードハウジング２内を仕切られて刈芝搬送通路４が形成されている。
刈芝搬送通路４は、ブレードハウジング２内を画成して形成された通路で、通路前端がブレード収容部２ｂに開口しており、同前端開口から後方へ通路断面積を徐々大きくしていき、膨出部２ｅの若干傾斜した後壁に大きな後端開口４ｂを形成している。 The blade housing 2 is partitioned by the vertical partition plate 3 (see FIG. 3) obliquely from the right side of the central portion 2c of the blade housing 2 to the bulging portion 2e of the latter half, so that the cut grass transport passage 4 is formed. .
The cut grass conveyance passage 4 is a passage formed by defining the inside of the blade housing 2, and the front end of the passage opens into the blade housing portion 2b, and the passage cross-sectional area gradually increases from the front end opening to the rear. A large rear end opening 4b is formed in a slightly inclined rear wall of the bulging portion 2e.

刈芝搬送通路４の後端開口４ｂは膨出部２ｅの後壁２ｄの右半部強を大きく開口しており、この後端開口４ｂに前端の口を連結して刈芝収集袋５が後方に延設される（図１参照）。   The rear end opening 4b of the cutting lawn conveying passage 4 has a large opening in the right half of the rear wall 2d of the bulging portion 2e. It extends rearward (see FIG. 1).

斜めの鉛直仕切板３によってブレードハウジング２内を仕切られて右側に刈芝搬送通路４が形成され、鉛直仕切板３より左側の空間の下半部に走行用ＤＣモータ30と減速機構40が設けられている。   The blade housing 2 is partitioned by an oblique vertical partition plate 3 to form a cut grass transport passage 4 on the right side, and a traveling DC motor 30 and a speed reduction mechanism 40 are provided in the lower half of the space on the left side of the vertical partition plate 3. It has been.

走行用ＤＣモータ30のモータ駆動軸31が減速機構40の上部に減速機構40の入力軸として挿入されており、モータ駆動軸31の回転が減速ギヤ群の噛合いを介して減速機構40の下部において出力軸である駆動軸50に減速されて伝達される。   A motor drive shaft 31 of the traveling DC motor 30 is inserted as an input shaft of the speed reduction mechanism 40 at the upper portion of the speed reduction mechanism 40, and the rotation of the motor drive shaft 31 is engaged with the speed reduction gear group at the lower portion of the speed reduction mechanism 40. In FIG. 2, the speed is reduced and transmitted to the drive shaft 50 which is the output shaft.

駆動軸50は、後輪７，７をそれぞれ回転自在に軸支する後車軸７ａ，７ａの後方において、左右に延びて回転自在に架設されており、駆動軸50の両端にクラッチ55を介して嵌着された駆動ギヤ61，61が後輪７，７に一体に固着された被動ギヤ62，62と噛合している。   The drive shaft 50 extends to the left and right behind the rear axles 7 a and 7 a that rotatably support the rear wheels 7 and 7, and is rotatably mounted on both ends of the drive shaft 50 via clutches 55. The fitted drive gears 61, 61 are engaged with driven gears 62, 62 integrally fixed to the rear wheels 7, 7.

したがって、走行用ＤＣモータ30のモータ駆動軸31の回転が、減速機構40を介して減速されて駆動軸50に伝達され、駆動軸50の回転がクラッチ55および駆動ギヤ61，61と被動ギヤ62，62の噛合いを介して後輪７，７の回転に伝達されて芝刈機１が走行される。   Therefore, the rotation of the motor drive shaft 31 of the traveling DC motor 30 is decelerated via the speed reduction mechanism 40 and transmitted to the drive shaft 50, and the rotation of the drive shaft 50 is transmitted to the clutch 55, the drive gears 61 and 61, and the driven gear 62. , 62 is transmitted to the rotation of the rear wheels 7 through the meshing of the lawn mower 1 to travel.

走行用ＤＣモータ30の駆動制御、内燃機関10の運転制御および内燃機関10の駆動をブレード12に伝達する前記電磁クラッチ20の接続・切断制御などは、全てコンピュータによる電子制御装置であるＥＣＵ70により実行される。   The drive control of the DC motor 30 for traveling, the operation control of the internal combustion engine 10 and the connection / disconnection control of the electromagnetic clutch 20 for transmitting the drive of the internal combustion engine 10 to the blade 12 are all executed by the ECU 70 which is an electronic control device by a computer. Is done.

このＥＣＵ70は、ブレードハウジング２の後部膨出部２ｅの上部で刈芝搬送通路４の鉛直仕切板３により仕切られた左側の空間の上半部に配設される。
ＥＣＵ70の下方に前記走行用ＤＣモータ30が位置する。 The ECU 70 is disposed in the upper half of the space on the left side partitioned by the vertical partition plate 3 of the cut grass transport passage 4 above the rear bulge portion 2e of the blade housing 2.
The traveling DC motor 30 is located below the ECU 70.

ＥＣＵ70は、直方体状の筐体に収容されており、筐体の上面には冷却フィン71が多数枚並んで長尺に突出形成されている。
ブレードハウジング２の後部膨出部２ｅの傾斜した上壁の一部が矩形に開口しており、その矩形口はＥＣＵ70の筐体の上面の長方形より若干小さく、同矩形口に下側から冷却フィン71を嵌挿して上部に露出させ、ＥＣＵ70の筐体の上面外周縁部を矩形口の開口縁部に当接してねじ72により固着してＥＣＵ70はブレードハウジング２の上壁に支持される。 The ECU 70 is housed in a rectangular parallelepiped housing, and a large number of cooling fins 71 are juxtaposedly formed on the upper surface of the housing.
A part of the inclined upper wall of the rear bulge portion 2e of the blade housing 2 opens in a rectangular shape, and the rectangular port is slightly smaller than the rectangular shape on the upper surface of the casing of the ECU 70, and the cooling fin is inserted into the rectangular port from below. 71 is inserted and exposed to the upper part, and the outer peripheral edge of the upper surface of the casing of the ECU 70 is brought into contact with the opening edge of the rectangular mouth and fixed by a screw 72 so that the ECU 70 is supported on the upper wall of the blade housing 2.

このようにしてブレードハウジング２の後部膨出部２ｅに取り付けられたＥＣＵ70は、図２に示すように内燃機関10より後方に離れており、ＥＣＵ70の本体が内燃機関10の上端より下方に位置している。   The ECU 70 attached to the rear bulge 2e of the blade housing 2 in this way is separated rearward from the internal combustion engine 10 as shown in FIG. 2, and the body of the ECU 70 is located below the upper end of the internal combustion engine 10. ing.

ブレードハウジング２の後部膨出部２ｅの上部からは、後方に操作ハンドル80が延設されている。
操作ハンドル80は、管状部材をコ字状の屈曲したもので、ブレードハウジング２の後部膨出部２ｅの左右側部から左右長柄部81Ｌ，81Ｒが後方へ幾らか上向きに長尺に延出し、その後端部どうしを握り部82が連結して操作ハンドル80を構成している。 From the upper part of the rear bulge 2e of the blade housing 2, an operation handle 80 is extended rearward.
The operation handle 80 is formed by bending a tubular member in a U-shape, and the left and right elongated handle portions 81L and 81R extend from the left and right side portions of the rear bulge portion 2e of the blade housing 2 to be slightly longer upwards. Thereafter, the grip 82 is connected between the end portions to constitute the operation handle 80.

操作ハンドル80には、ブレードレバー85や走行レバー86等の操作部材が配設されており、作業者が操作ハンドル80の握り部82を持ってブレードレバー85や走行レバー86を操作しながら芝刈機１を操縦するようになっている。   The operation handle 80 is provided with operation members such as a blade lever 85 and a travel lever 86, and the lawn mower is operated while the operator holds the grip portion 82 of the operation handle 80 and operates the blade lever 85 and the travel lever 86. It is designed to steer 1.

本芝刈機１は概ね以上のように構成されており、内燃機関10の後方で刈芝搬送通路４の側方の鉛直仕切板３により仕切られた隣接した空間に走行用ＤＣモータ30が配置されるので、刈芝搬送通路４を備えながらブレードハウジング２内のデッドスペースを有効に利用して走行用ＤＣモータ30が配置され、芝刈機１全体のコンパクト化を図ることができる。   The lawn mower 1 is generally configured as described above, and the traveling DC motor 30 is disposed in the adjacent space partitioned by the vertical partition plate 3 on the side of the mowing lawn conveyance passage 4 behind the internal combustion engine 10. Therefore, the traveling DC motor 30 is arranged by effectively using the dead space in the blade housing 2 while having the mowing lawn conveyance passage 4, and the overall lawn mower 1 can be made compact.

また、走行用ＤＣモータ30は内燃機関10の後方に位置してブレードハウジング２内にあるので、異物との衝突や粉塵による可動不良を回避することができる。   In addition, since the traveling DC motor 30 is located behind the internal combustion engine 10 and is in the blade housing 2, it is possible to avoid a malfunction due to collision with foreign matter or dust.

ＥＣＵ70が走行用ＤＣモータ30の上方に配置されるので、走行用ＤＣモータ30と同様にＥＣＵ70もブレードハウジング２内のデッドスペースを利用して配置され、芝刈機１全体のコンパクト化に寄与するとともに、内燃機関10の後方にＥＣＵ70を位置してブレードハウジング２内にあり、ＥＣＵ70の異物との衝突を回避することができる。   Since the ECU 70 is disposed above the traveling DC motor 30, the ECU 70 is disposed using the dead space in the blade housing 2 in the same manner as the traveling DC motor 30 and contributes to the downsizing of the lawn mower 1 as a whole. The ECU 70 is located behind the internal combustion engine 10 and is in the blade housing 2, so that it is possible to avoid collision of the ECU 70 with foreign matter.

また、ＥＣＵ70と走行用ＤＣモータ30とを結ぶ結線も短くてすみ、メンテナンス性が向上するとともに、電圧降下も抑制することができる。   Further, the connection between the ECU 70 and the traveling DC motor 30 can be shortened, so that maintainability is improved and a voltage drop can be suppressed.

走行用ＤＣモータ30の駆動を減速して駆動軸50に伝達する減速機構40が、走行用ＤＣモータ30の下方に配置されるので、走行用ＤＣモータ30とともに減速機構40もブレードハウジング２内のデッドスペースを利用して配置され、芝刈機全体のコンパクト化に寄与する。   Since the speed reduction mechanism 40 that decelerates the driving of the traveling DC motor 30 and transmits it to the drive shaft 50 is disposed below the traveling DC motor 30, the speed reduction mechanism 40 together with the traveling DC motor 30 is included in the blade housing 2. It is arranged using dead space and contributes to the downsizing of the whole lawn mower.
