DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paddy field working machine such as a rice transplanter and, more particularly, to a seedling machine at the rear of a riding type self-propelled machine having a prime mover at the front and a driving seat at the rear. A paddy field working device such as a planting device is connected, and the front part of the self-propelled machine is composed of left and right columns and a gripping operation rod connecting the upper ends thereof, and has an action posture projecting forward. The present invention relates to an apparatus in which an operation tool that can freely perform swing switching operation is arranged around a left-right-facing axis with a standing storage posture.

[0002]

2. Description of the Related Art In a paddy working machine such as this type of rice transplanter,
In front of the driver's seat, more preferably in front of the self-propelled machine,
It is necessary to dispose a travel indicator in order to perform the straight traveling stably and favorably. Conventionally, as seen in Japanese Patent Application Laid-Open No. 2000-37119, a stay is provided between the left and right columns of the operating tool, and the stay is swingably switched between an operating posture in which the travel indicator is upright and an inverted storage posture. A configuration provided operably is known.

[0003] The operating tool is mainly used to push down the front part of the self-propelled machine to prevent the front part of the self-propelled machine from being lifted by the weight of a paddy working device connected to the rear part when crossing a ridge or unloading a truck bed. It was developed for the purpose. Then, when traveling by operating the operating tool, the paddy field working machine is in a relatively unstable posture, so that an immediate stop may be required. Therefore, conventionally, as can be seen in Japanese Patent Application Laid-Open No. 2000-37119, an operation arm is provided on the side of the prime mover to operate a clutch for intermittently transmitting power to the traveling unit and a brake for the traveling system. By operating the operating arm, the operator operating the operating tool cuts off the transmission to the traveling unit and stops the traveling by braking.

[0004] As a paddy field working machine provided with an operating tool, there is known a paddy working machine as disclosed in Japanese Patent Application Laid-Open No. 2000-37119. This is because the transmission to the left and right driving rear wheels is intermittently interrupted, and the left and right steering clutches and brakes for braking the driving rear wheels in the transmission interrupted state are provided, and these steering clutches and brakes are specially operated. Two steering clutch pedals are arranged side by side so that both can be depressed and operated with one foot, and a main clutch that interrupts transmission to the traveling system and a main clutch pedal that operates it are provided.
The travel is stopped by depressing both the left and right steering clutch pedals and depressing the main clutch pedal.

Further, as a paddy working machine provided with this kind of operating tool, as shown in the above-mentioned Japanese Patent Application Laid-Open No. 2000-37119, the swinging posture of the operating tool can be changed and fixed in a plurality of stages. Things are known.

[0006]

However, the prior art described above has the following disadvantages.

In the case where the travel index tool is attached to the stay fixed to the operation tool so as to be swingably switchable between the operating posture and the retracted posture, a stay and a support shaft for swingably switching the travel index tool are provided. However, the number of components increases the complexity of the structure and the cost.

When an operation arm is provided on the side of the prime mover so that the operator operating the operating tool can stop traveling, the operator operating the grip operating rod of the operating tool can be used. Even if the distance from the operation arm is increased, the operator is not incapable of performing the operation, but is forced to perform a considerably difficult posture in the operation, and there is room for improvement in operability.

When the body is stopped by depressing the left and right steering clutch pedals and the main clutch pedal, the three pedals must be depressed when the body is stopped, so that the operability is poor.

Some paddy working machines are provided with a hydrostatic continuously variable transmission capable of switching forward and backward as a traveling transmission. In such a device, the operation can be performed from a driver seat and operating tools can be operated. It is common to set a shift lever for the continuously variable transmission so that a worker who is working can also operate it. When the swinging posture of the operating tool can be changed and fixed in a plurality of stages, the swinging posture of the operating tool, that is, the distance between the grip operating rod and the shift lever is adjusted according to the physique or the like of the worker. In addition, the operator who operates the operating tool can stop the machine body by operating the continuously variable transmission in the neutral state with good operability. However, in the case where the operating tool is fixed in each swinging posture as in the related art, when the operating tool is swung to the retracted position, the fixing must be released one by one. There was a drawback that it lacked sex.

An object of the present invention is to eliminate the above-mentioned conventional disadvantages.
