Claims

[Scope of utility model registration request]

A front wheel and a transmission case are installed at the bottom of the frame on which the prime mover is mounted, and the main shaft is supported at the top of the transmission case, and the axle of the rear drive wheel is supported at the bottom end of the transmission case, thereby transmitting power to the driving shaft and main shaft of the prime mover, and to the main shaft and axle, respectively. Connected by a mechanism,
In an automatic deep cultivator, in which a crank for driving and operating a hoe is installed on the rear part of the frame by a crankshaft, an idling clutch ring is attached to the main shaft so that it can only rotate freely, and an operating clutch ring is attached so that it can only slide freely. Clutch pawls that engage and disengage each other are provided on opposing surfaces of those clutch rings, respectively,
A cam with a low point is attached to the crankshaft, and the idling clutch ring and the crankshaft are connected by a transmission mechanism, and the rear mounting ring of the clutch lever is supported in the middle by a vertical axis so as to be rotatable from side to side. Fitted into the operating clutch ring, the front part of the clutch lever can be alternately engaged in the locking recesses of the locking plate for clutch engagement and clutch disengagement, and is urged toward the clutch disengagement side by a spring; A roller at the rear end of a cam interlocking rod, which is provided on the frame so as to be movable back and forth opposite the cam and is pressed backward by a spring, comes into contact with the cam, and a clutch lever is attached to the front end of the cam interlocking rod to engage the clutch. A crank stop device in which a hook that fits into a clutch lever when engaged in a stop recess is pivotally supported so as to be rotatable only rearward, and is urged forward by a spring.
