が備えられている歩行型耕耘機に関する。DETAILED DESCRIPTION OF THE INVENTION According to the present invention, a rotary tilling device is provided to a machine equipped with a drive wheel, and the rotary tilling device is located at the rear of the drive wheel. The present invention relates to a walk-behind cultivator equipped with a ground movable detector that automatically and reversibly disconnects a clutch to the rotary tiller in conjunction with the rise of the rotary tiller above a certain level from the ground due to movement of the rotary tiller.
上記のように、駆動輪を支点にして、機体を前
後方向に傾斜させて、ロータリ耕耘装置のクラツ
チを入切する技術としては、従来、実公昭54−
13129号公報に開示の技術が知られている。 As mentioned above, the conventional technique for turning on and off the clutch of a rotary tiller by using the drive wheels as a fulcrum and tilting the machine in the front and back direction is
A technique disclosed in Publication No. 13129 is known.
この構造のものは、駆動輪前方の機体下部に、
機体を前傾させた時に接地する接地板兼用のロー
タリクラツチ入切用センサーを設けてあつた。 With this structure, there is a
A rotary clutch on/off sensor was installed that also served as a ground plate that touched the ground when the aircraft was tilted forward.
一般に、圃場端部の表面は、泥面が荒れている
場合が多く、従つて、その表面の凹凸による機体
傾斜角の変動により、ロータリクラツチが常に一
定した機体傾斜角で切れず危険であつた。 Generally, the surface of the edge of a field is often rough with mud, and the rotary clutch cannot always be disengaged at a constant angle of inclination due to fluctuations in the angle of inclination due to the unevenness of the surface, which is dangerous. .
つまり、駆動輪が凸に乗り上つてロータリクラ
ツチが切れる場合と、駆動輪が凹に陥込んでロー
タリクラツチが切れる場合とでは、凸に乗り上が
つている場合の方がロータリクラツチが切れにく
い。つまり、機体が大きく前傾しないと切れにく
く危険であつた。 In other words, the rotary clutch is more difficult to disengage when the drive wheel rides on a convex surface than when the drive wheel rides on a convex surface, and when the rotary clutch disengages when the drive wheel rides on a convex surface. In other words, unless the aircraft tilted forward significantly, it was difficult to cut and it was dangerous.
本発明は、ロータリクラツチ入切用センサーの
配設構造と工夫することによつて、上記欠点を解
消することを目的とする。 An object of the present invention is to eliminate the above-mentioned drawbacks by devising the arrangement structure of the rotary clutch on/off sensor.
上記目的を達成する為の本発明の特徴構成は、
前記検出具を、前記駆動輪の通過跡の幅内で、且
つ、前記ロータリ耕耘装置の前方に配設した点に
あり、その作用効果は次の通りである。 The characteristic structure of the present invention for achieving the above object is as follows:
The detection tool is disposed within the width of the path of the drive wheel and in front of the rotary tiller, and its effects are as follows.
すなわち、駆動輪によつて圃場表面の凹凸が均
された後をロータリクラツチ入切用センサーとし

の凹凸による影響を受けにくく、従つて、ロータ
リクラツチを、常に一定した機体傾斜角のもとで
切ることができ、ロータリ耕耘装置を持上げての
機体旋回時の安全性を高めることができる。 In other words, since the ground-based movable detector, which serves as a sensor for turning on and off the rotary clutch, passes after the unevenness of the field surface has been smoothed out by the drive wheel, it is less affected by the unevenness of the field surface, and therefore the rotary clutch The rotary tiller can be cut under a constant angle of inclination of the machine, increasing safety when turning the machine while lifting the rotary tiller.

る。 As shown in FIG. 1, a transmission case 3 in which one driving wheel 2 is rotatably supported is supported at the rear of the front frame 1, and an engine 4 is mounted thereon, and the transmission case 3 is mounted rearward and upward. A main machine 6 is constructed by extending the control handle 5, and a removable rotary tilling device 8 is connected to the main machine 6, so that the operator automatically travels and plows while supporting the control handle 5. It is configured as a single-wheel walking type tiller. Furthermore, a ground-type movable detector 9 is attached to the transmission case 3, and as shown in FIGS. The detection tool 9 swings around the horizontal axis P, and the swing is transmitted to the inner wire 10a and the outer wire 10.
b, so that the transmission is transmitted to a clutch 11 attached to the main machine side of the rotary tilling device 8, and as the rotary tilling device 8 rises above a certain level, the clutch 11 is automatically and reversibly disconnected. It is configured so that Further, the ground contact point 9a of the detection tool 9 is located immediately behind the drive wheel 2 and has a ground contact width l.
The detector 9 is located inside the vehicle body, and is configured to prevent the detector 9 from erroneously detecting even if the aircraft body is tilted in the lateral direction.
