[Prior Art]

 2. Description of the Related Art Conventionally, there has been known a device equipped with a cutic pedal lock device that holds a clutch in a disengaged state for long-term storage of a mobile agricultural machine. In Japanese Utility Model Laid-Open No. 49-127306, there is known a device for adjusting and displaying a clutch pedal in a tractor in which a play adjusting index is provided on a side wall of a vehicle body near a clutch petal. By the way, the former one is equipped only to lock the clutch pedal, so when adjusting the play of the clutch pedal, it is still necessary to adjust the optimum play position by depressing the clutch pedal. Was annoying. The latter allows the clutch pedal to be adjusted while looking at the play adjustment index, but this one also adjusts the play so that the clutch pedal is held down to the play adjustment index position while the clutch and pedal are held. It is necessary to adjust the adjustment metal fittings such as the turnbuckle provided on the rod etc., and it is difficult to adjust by one person's work, and the clutch pedal needs to be held separately by one person's work. Met.

[Problems to be solved by the device]

 The present invention has been made in view of the above circumstances to solve the conventional drawbacks, and its purpose is to provide a part of the lock member equipped to prevent the clutch from sticking. An adjustment locking part is provided to adjust the play of the cutic pedal so that the play can be easily adjusted while the clutch pedal is temporarily held in the adjustment locking part. It was done.

[0004]

[Means for Solving the Problems]

 In order to solve the problem, the technical means adopted by the present invention is to provide a lock member, which holds the depressed state of the clutch pedal, in the vicinity of a clutch pedal provided on the side portion of the machine body such as a tractor so as to be rotatable. In the mobile agricultural machine pivotally supported on the lock member, a lockable portion is provided on the locked member of the lock member, and the free end side of the lock member can be locked on the locked member of the clutch pedal. The adjustment locking portion is provided, and the play of the clutch pedal is adjusted while the adjustment locking portion is locked to the locked member.

[0005]

[Action]

Therefore, according to the present invention, the state before the play adjustment of the clutch pedal 4 is shown in FIG. 2 and FIG. 3 in the state where the clutch pedal 4 is depressed from the position a to the position b by L ₁ and the lock member 13 is pivoted about the lower end pivotal support portion 13a. Is rotated in the direction of the arrow to temporarily hold the adjustment locking portion 15 of the lock member 13 on the locked member 4d of the foot step plate 4c of the clutch pedal 4, and then, in this state, the clutch arm 11 is locked. Check if there is a gap between the clutch and the release fork (not shown) connected to the. If there is a gap when the clutch pedal 4 is locked, install it on the connecting rod 10 between the protrusion 8 and the clutch arm 11. Adjusting the adjusting member 12 such as the turnbuckle to eliminate the gap, and in this state, remove the adjusting stop 15 of the lock member 13 from the locked member 4d of the clutch pedal 4 so that the clutch pedal 4 has proper play. When It, play adjustment of the clutch pedal 4 is completed. In FIG. 4, the lock member 13 is rotated in the direction of the arrow while the clutch pedal 4 is fully depressed from the position a to the position c by L ₂ , and the locking portion 14 of the lock member 13 is engaged with the locked member 4d of the clutch pedal 4. The lock state is shown to prevent the clutch from sticking when a mobile agricultural machine such as a tractor is stored for a long period of time.

【Example】

 The configuration of the present invention will be described in detail with reference to an embodiment shown in the drawings. In FIG. 1, reference numeral 1 is a tractor, and the tractor 1 has front wheels 2a and 2b and rear wheels 3a and 3b, and is configured to transmit power from an engine (not shown) to the rear wheels. The clutch pedal 4 includes a base end portion 4a pivotally supported by a pivot shaft 6 below the step 5, a pedal arm 4b extending upward from the base end portion 4a to the step 5, and a pedal arm. It comprises a foot plate 4c fixed to the free end of 4b, and a locked portion 4d integrally provided on the back surface of the foot plate 4c. The locked portion 4d of the clutch pedal 4 can be selectively locked by a locking portion 14 and an adjusting locking portion 15 of a lock member 13 described later. Reference numeral 7 is a bracket for fixing the pivot shaft 6 to the lower surface of the tractor 1. Reference numeral 8 denotes a protrusion fixed to the base end 4a of the clutch pedal 4, and a return spring 9 for the clutch pedal 4 is provided between the step 5 and the protrusion 8. Reference numeral 10 is a connecting rod for connecting the clutch arm 11 and the projecting piece 8, and the connecting rod 10 is provided with an adjusting member 12 such as a turnbuckle. Reference numeral 13 denotes a lock member that is rotatable on a pivotally supporting portion 13a pivotally supported at the lower end of the body side. The lock member 13 has a locking portion 14 for holding the clutch pedal 4 in a locked state and a play of the clutch pedal 4. An adjustment locking portion 15 for adjusting the is provided. The locking portion 14 and the adjustment locking portion 15 are provided near the pivotal support portion of the lock member 13 and on the free end side, respectively.

In the present invention, the adjustment locking portion 15 for adjusting the play of the clutch pedal is provided on the lock member 13, but the parking brake member (not shown) for holding the depressed state of the left and right brake pedals is provided. It is also possible to adjust the play of the brake pedal by providing an adjustment locking portion for adjusting the play of the brake pedal.

[Effect of the device]

 In short, the present invention provides a mobile agricultural machine in which a lock member for holding the depressed state of the clutch pedal is pivotally supported on the side of the machine body near the clutch pedal provided on the side of the machine body such as a tractor. A locking portion for holding the clutch pedal in a locked state is provided near the pivotal support portion of the lock member, and a locking portion capable of locking with a locked member of the clutch pedal is provided on a free end side of the lock member. In addition, the adjustment locking portion that can be locked to the locked member of the clutch pedal is provided on the free end side of the locking member, and the adjustment locking portion is locked to the locked member. This is a clutch pedal adjustment device that adjusts the play of the clutch pedal by adjusting the play of the clutch pedal to the lock member mounted on the aircraft to prevent the clutch from sticking when storing for a long time. Since the adjustment locking part is integrally provided, the lock member is effectively used not only for preventing the clutch from sticking by the lock member but also for adjusting the play of the clutch pedal, so that the number of parts can be reduced by sharing the parts. The clutch pedal play adjustment work, however, can be easily performed by one person alone.
