It is easy to connect.

次に、操作レバー１７の安全装置Ｔについての説明をする。
操作レバー１７は横軸心の支点３０周りに回動する構成とし、支点３０の前側に形成するスイッチ操作部１７ａと、支点３０の後側に形成する把持部１７ｂとを設ける。３３はモータ８の駆動を入切するリミットスイッチでスイッチ操作部１７ａの回動動作によりモータ８の駆動の入切が行なわれる。２５は把持して回動させた操作レバー１７を初期位置に戻すスプリングである。 Next, the safety device T for the operation lever 17 will be described.
The operating lever 17 is configured to rotate around the fulcrum 30 of the horizontal axis, and is provided with a switch operating part 17 a formed on the front side of the fulcrum 30 and a gripping part 17 b formed on the rear side of the fulcrum 30. Reference numeral 33 denotes a limit switch for turning on / off the driving of the motor 8, and the driving of the motor 8 is turned on / off by the turning operation of the switch operating portion 17a. Reference numeral 25 denotes a spring for returning the operating lever 17 gripped and rotated to the initial position.

安全装置Ｔについて以下説明する。
把持部１７ｂの上方にあって把持部１７ｂと交差する方向に形成し、左右方向に移動する移動軸３１を設ける。移動軸３１の機体内側端には移動軸３１を機体外側に向かって押し出し操作するための押し部３１ｃを形成し、押し部３１ｃに隣接してスプリング３５を移動軸３１に巻回する構成としている。移動軸３１は機体内側から順に小径部３１ａと大径部３１ｂとを隣接して形成している。そして、安全装置Ｔの初期位置では大径部３１ｂが把持部１７ｂの回動軌跡上に位置する構成としている（図７の（イ）参照）。 The safety device T will be described below.
A moving shaft 31 that is formed above the gripping portion 17b and intersects the gripping portion 17b and moves in the left-right direction is provided. A pushing portion 31c for pushing the moving shaft 31 toward the outside of the body is formed at the inner end of the moving shaft 31, and a spring 35 is wound around the moving shaft 31 adjacent to the pushing portion 31c. . The moving shaft 31 is formed with a small diameter portion 31a and a large diameter portion 31b adjacent to each other in order from the inside of the machine body. And it is set as the structure which the large diameter part 31b is located on the rotation locus | trajectory of the holding part 17b in the initial position of the safety device T (refer (i) of FIG. 7).

操作レバー１７と安全装置Ｔの耕耘作業時の操作について以下説明する。
電源スイッチ１６を入りにして、押し部３１ｃを親指で押すと、移動軸３１が機体外側に向かって横移動し、大径部３１ｂが機体外側に移動し、小径部３１ａが操作レバー１７の回動軌跡上に位置する（図７の（ロ）参照）。そして、作業者が把持部１７ｂを把持するとスイッチ操作部１７ａと把持部１７ｂがリミットスイッチ３３が入りとなる位置まで回動し、モータ８が駆動しロータリ部Ｒが回転して耕耘作業が行われる（図６（ロ）参照）。耕耘作業が始まると、把持部１７ｂと小径部３１ａとが当接状態となっており、把持部１７ｂが大径部３１ｂが初期位置に戻るのを止めるため、作業者は押し部３１ｃを離し、把持部１７ｂを把持した状態で耕耘作業を継続できる。 The operation at the time of tilling work of the operation lever 17 and the safety device T will be described below.
When the power switch 16 is turned on and the pushing portion 31c is pushed with the thumb, the moving shaft 31 moves laterally toward the outside of the machine body, the large diameter part 31b moves to the outside of the machine body, and the small diameter part 31a turns the operation lever 17. It is located on the movement locus (see (b) in FIG. 7). When the operator grips the gripping part 17b, the switch operating part 17a and the gripping part 17b rotate to a position where the limit switch 33 is turned on, the motor 8 is driven and the rotary part R rotates to perform the tilling work. (See FIG. 6 (b)). When the plowing work is started, the gripping portion 17b and the small diameter portion 31a are in contact with each other, and the gripper 17b stops the return of the large diameter portion 31b to the initial position. Tillage work can be continued with the gripping portion 17b gripped.

耕耘作業を停止するときには、作業者が把持部１７ｂを離すとスプリング２５の作用でスイッチ操作部１７ａが初期位置まで回動し、リミットスイッチ３３が切られてロータリ部Ｒは停止する（図６（ハ）参照）。また、スプリング３５の作用で移動軸３１が機体内側に移動し、初期位置に戻る。   When stopping the tilling work, when the operator releases the gripping portion 17b, the switch operating portion 17a is rotated to the initial position by the action of the spring 25, the limit switch 33 is turned off, and the rotary portion R is stopped (FIG. 6 ( See c). Further, the moving shaft 31 moves to the inside of the machine body by the action of the spring 35 and returns to the initial position.

作業者が電源スイッチ１６を入りにした状態で電動耕耘機を持ち運んでいるときに、不意に操作レバー１７の把持部１７ｂに当接して把持部１７ｂが回動しても、把持部１７ｂが移動軸３１の大径部３１ｂに当接して、スイッチ操作部１７ａがリミットスイッチ３３の入り位置まで回動せず、リミットスイッチ３３は入りされない（図６の（イ）参照）。押し部３１ｃを押した状態で把持部１７ｂを操作しなければロータリ部Ｒは回転しないため、電源スイッチ１６が入り状態であることを作業者が気がつかずに持ち運んでいるときに不意にロータリ部Ｒが回転することがないので安全である。   Even when the operator is carrying the electric power tiller with the power switch 16 turned on, the gripping portion 17b moves even if the gripping portion 17b rotates unexpectedly by contacting the gripping portion 17b of the operating lever 17 The switch operating portion 17a does not rotate to the position where the limit switch 33 is engaged by coming into contact with the large diameter portion 31b of the shaft 31, and the limit switch 33 is not entered (see (A) of FIG. 6). The rotary portion R does not rotate unless the gripping portion 17b is operated while the push portion 31c is pressed. Therefore, the rotary portion R is unexpectedly carried when the operator carries the power switch 16 without knowing that the power switch 16 is turned on. Is safe because it never rotates.

次に電動耕耘機を持ち運ぶときの構成を以下説明する。
３６は左右の操作ハンドル１２ａ，１２ｂの前後位置を固定・調節するための調節ネジで、調節ネジ３６を緩めて操作ハンドル１２ａ，１２ｂを横軸心の回動支点３７周りに機体前側に倒し、調節ネジ３６を締めて位置固定する（図５参照）。すると、左右の操作ハンドル１２ａ，１２ｂとを連結する連結棒３８が機体の前後長の略中央で機体の略重心位置で、かつバッテリケース９の上方に位置する構成としている。作業者は連結棒３８、又は連結棒３８と機体前端のバンパー３９を持って電動耕耘機を持ち運ぶことで、持ち運び時にバッテリケース９が外れるのを防止することができる。また、連結棒３８は左右の操作ハンドル１２ａ，１２ｂを前側に倒したときに正面視で略門構えになる構成としており、バッテリケース９に当接しないで左右の操作ハンドル１２ａ，１２ｂをより下まで倒せる構成としている。４０は持ち運び時にロータリ部Ｒの下を覆う位置に取り付けるバケットで、バンド（図示せず）等で機体に装着する構成で、ロータリ部Ｒに付着する土が落下するのを受け、持ち運び時に土が周辺に散乱するのを防止することができる。 Next, the configuration when carrying the electric field cultivator will be described below.
Reference numeral 36 denotes an adjustment screw for fixing and adjusting the front and rear positions of the left and right operation handles 12a and 12b. The adjustment screw 36 is loosened and the operation handles 12a and 12b are tilted around the pivot point 37 of the horizontal axis toward the front of the aircraft. The adjustment screw 36 is tightened to fix the position (see FIG. 5). Then, the connecting rod 38 that connects the left and right operation handles 12a, 12b is configured to be positioned at the approximate center of the longitudinal direction of the fuselage at the approximate center of gravity of the fuselage and above the battery case 9. An operator can prevent the battery case 9 from being detached when carrying the electric tiller by holding the connecting rod 38 or the connecting rod 38 and the bumper 39 at the front end of the machine body. Further, the connecting rod 38 is configured to have a substantially gate structure when viewed from the front when the left and right operation handles 12a and 12b are tilted forward. It can be defeated. Reference numeral 40 denotes a bucket that is attached to a position covering the bottom of the rotary part R when being carried, and is configured to be attached to the machine body with a band (not shown) or the like. Scattering to the surroundings can be prevented.

次に本実施の形態の電動耕耘機の前後バランスの構成について以下説明する。

The axial center of the motor shaft 8a of the motor 8 arranged in the vertical direction is configured in front of the axial center position of the rotary shaft 4, a battery case 9 is provided behind the axial center position of the rotary shaft 4, and the battery case 9 The handle frame 11 is provided at the rear. With this configuration, a center of gravity is obtained near the battery case 9, and even if the capacity of the battery accommodated in the battery case 9 is changed to change the weight of the battery case 9, the change in the center of gravity of the body is small.

次にＬＥＤの構成について以下説明する。
電源スイッチ１６の近傍に各種運転状態を示す複数のＬＥＤ２６を設けている。本実施の形態では、電源の入り切りのＬＥＤ２６ａ、運転の入り切りのＬＥＤ２６ｂとバッテリ残量のＬＥＤ２６ｃを設けている。電源の入り切りのＬＥＤ２６ａでは電源スイッチ入りで第一の色である緑色が発光し、過負荷を検出して配線２０に設ける保護回路（図示せず）が作動すると第二の色である赤色が発光する。運転の入り切りのＬＥＤ２６ｂではリミットスイッチ３３が入りしてロータリ部Ｒが駆動すると第一の色である緑色が発光し、モータ８内蔵の温度センサーによる保護回路（図示せず）が作動すると第二の色である赤色が発光する。バッテリ残量のＬＥＤ２６ｃではバッテリの残量が通常の状態では第一の色である緑色が発光し、残量が設定量以下になると第二の色である赤色が発行する。 Next, the configuration of the LED will be described below.
A plurality of LEDs 26 indicating various operating states are provided in the vicinity of the power switch 16. In the present embodiment, a power on / off LED 26a, an operation on / off LED 26b, and a battery remaining amount LED 26c are provided. The power on / off LED 26a emits green as the first color when the power switch is turned on, and emits red as the second color when an overload is detected and a protection circuit (not shown) provided on the wiring 20 is activated. To do. When the limit switch 33 is turned on and the rotary portion R is driven in the on / off LED 26b, green is emitted as the first color, and the second circuit is activated when a protection circuit (not shown) by a temperature sensor built in the motor 8 is activated. The color red emits light. The battery remaining amount LED 26c emits green, which is the first color, when the remaining amount of the battery is normal, and emits red, which is the second color, when the remaining amount is equal to or less than the set amount.

このように、各種運転状態をＬＥＤで表示し、また、第一の色から第二の色に適宜変色することで少ないＬＥＤの数で多くの動作表示を行なうことができ、また、一箇所に集中して、かつ、操作側から見やすい位置にＬＥＤを配置することで各種運転状況を確認しやすい。また、電源スイッチ１６に隣接してＬＥＤを設けたことで、電源入りから電源切の際にＬＥＤを常に確認しやすい。   In this way, various operation states are displayed with LEDs, and by appropriately changing the color from the first color to the second color, a large number of operation displays can be performed with a small number of LEDs, and in one place. It is easy to check various driving situations by placing the LEDs in a concentrated position that is easy to see from the operation side. Further, by providing the LED adjacent to the power switch 16, it is easy to always check the LED when the power is turned on and the power is turned off.

本実施の形態では電動耕耘機で説明したが、駆動音が無い他のエネルギーを利用した歩行型の作業機にも利用可能性がある。   Although this embodiment has been described with an electric power tiller, it may also be used for a walking-type working machine that uses other energy that does not have a driving sound.
