Abstract

(57) [Abstract] [PROBLEMS] In a mobile agricultural machine, an engine can be safely started by an operator in the driver's seat depressing a main clutch pedal to disengage the main clutch. SOLUTION: A grip 4 at the tip of a starting rope 3 extending from a recoil starter 2 of an engine E is provided near a driver's seat 1.
In a mobile agricultural machine in which the main clutch pedal 5 is provided and the main clutch is not depressed, the grip 4 moves from the driver's seat 1 to an inoperable position or the grip 4 recoil starter. When the main clutch pedal 5 is stepped down and operated to disengage the main clutch, the grip 4 moves to a position where it can be operated from the driver's seat 1 by interlockingly interlocking with the main clutch pedal 5 so that at least a part of it can be locked inoperable. Alternatively, at least a part of the grip 4 to the recoil starter 2 can be unlocked in an operable manner.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an engine start safe operating device for a mobile agricultural machine in which the engine cannot be started unless the main clutch pedal is depressed to operate the main clutch disengagement.

[0002]

2. Description of the Related Art Conventionally, as seen in, for example, Japanese Utility Model Laid-Open No. 3-611161, a mobile agricultural machine has a grip of a starting rope extending from a recoil starter of an engine and a main clutch pedal disposed near a driver's seat. , If the main switch is turned on, even with the main clutch engaged,
It was possible to start the engine while squeezing the grip and operating the recoil starter.

[0003]

However, in mobile agricultural machinery, many beginners, in particular, forget to turn off the main clutch without depressing the main clutch pedal, grasp the grip and operate the recoil starter to start the engine. There is a problem in that it may be started, and in a mobile agricultural machine, each operating unit is driven with the main clutch still engaged, which is dangerous.

[0004]

SUMMARY OF THE INVENTION The present invention solves such a problem and enables the engine to be safely started. Therefore, the engine is extended near the driver's seat from the recoil starter of the engine. In a mobile agricultural machine equipped with a grip of the starting rope tip and a main clutch pedal, when the main clutch is not depressed and the main clutch is engaged, the grip moves from the driver's seat to an inoperable position or recoil from the grip. When the main clutch pedal is interlocked and linked so that at least a part of the starter can be locked so that it cannot be operated, and the main clutch pedal is depressed to operate to disengage the main clutch, the grip moves to a position where it can be operated from the driver's seat or At least part of the grip to the recoil starter is operably unlocked It is intended.

[0005]

Therefore, when the operator in the driver's seat turns on the main switch to start the engine and the driver forgets to operate the main clutch disengagement without depressing the main clutch pedal, the grip will be in a position inoperable from the driver's seat. There is, or at least a part from the grip to the recoil starter is inoperably locked, and the operator cannot start the engine, but first, when the main clutch pedal is depressed to operate the main clutch disengagement,
The grip moves from the driver's seat to an operable position, or at least part of the grip to the recoil starter is operably unlocked, and the operator grasps the grip to safely start the engine. be able to.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a side view showing a part of a riding rice transplanter, which is a mobile agricultural machine, and a main unit A having a planting section B connected to the rear via a link mechanism 6 is at the bottom. Four front wheels 7 and two rear wheels 8 are provided, the driver's seat 1 is provided above the seat column 10 standing upright at the rear of the step 9, the main clutch pedal 5 is provided at the left front of the step 9, and the right clutch pedal 5 is provided at the right. Both left and right brake pedals 11a and 11b are provided in front of the engine E, and a main switch 13 and a steering wheel 14 are provided on a panel on the rear side of the bonnet 12 which is attached above the engine E.
Deploy and configure.

Further, a starter rope 3 extending from the recoil starter 2 of the engine E is laid around the idler wheel 15 near the recoil starter 2 and the seat column 10.
Wheel 1 axially mounted below the part of step 9 approaching
6 and step 9 above the idler wheel 16
A grip 4 that can be gripped by the operator of the driver's seat 1 with his / her right hand is connected to the tip of the starting end rope 3 extending from the opening 17 formed in the region of the idle wheel 16
A boss 21 at the base of a support arm 20 capable of engaging the grip 4 is loosely fitted to the support shaft 19 of the, and the support arm 20 is rotated around the support shaft 19 so that the upper direction of the opening 17 is increased. From the position where it can be operated from the driver's seat 1, the opening 1
It is configured such that the grip 4 can be moved from the driver's seat 1 to a position where it cannot be operated due to the inner direction of the opening 17a formed in the lower portion of the seat column 10 communicating with 7.

A supporting shaft 18 which is horizontally provided below the step 9
The boss 22 of the base of the arm 5a of the main clutch pedal 5 is fitted and fixed to the left end of the main clutch pedal 5, and the arm 23 projecting from the boss 22 is interlockingly connected to the main clutch of the machine body as in the conventional type. The boss 24 fitted and fixed to the right end of the support shaft 18 is provided with an arm 26 which is parallel to the arm 25 projecting from the boss 21, and the interlocking link 27 is provided at the tips of both arms 25, 26. It is configured by connecting both ends.

Therefore, when the operator in the driver's seat 1 turns on the main switch 13 to start the engine E, if he or she forgets to operate the main clutch disengagement without depressing the main clutch pedal 5, as shown in FIG. , Both arms 24, 2 by the main clutch pedal 5 not depressed
The support arm 20 is rotated inward of the opening 17a through the gear 5 and the interlocking link 27, and the grip 4 is moved from the driver's seat 1 to the inoperable position, so that the engine cannot be started. .

At this time, when the main clutch pedal 5 is normally depressed to operate to disengage the main clutch, both arms 2 are rotated by the rotation of the support shaft 18, as shown in FIGS. 1 to 4.
4, 25 and the support arm 20 via the interlocking link 27.
Is rotated inward of the opening 17 to move the grip 4 from the driver's seat 1 to a position where it can be operated, and the operator in the driver's seat 1 grips the grip 4 with the right hand and moves upward with the arrow arrow. The engine E can be started by pulling as shown by.

The grip 4 or the starting rope 3
Alternatively, a lock means capable of locking the recoil starter 2 is provided, and an operator in the driver's seat 1 operates the lock means via a microswitch or the like with the main clutch engaged without depressing the main clutch pedal 5. It can also be configured to lock improperly.

[0012]

As described above, according to the present invention, when the operator of the driver's seat 1 turns on the main switch to start the engine E, if the operator forgets to operate the main clutch disengagement without depressing the main clutch pedal 5, The grip 4 is in a position inoperable from the driver's seat 1 or at least a part from the grip 4 to the recoil starter 2 is locked so that the operator cannot start the engine E. When the main clutch pedal 5 is depressed and the main clutch is normally disengaged, the grip 4 moves from the driver's seat 1 to an operable position, or at least part of the grip 4 to the recoil starter 2 is operably locked. Since it is released, the operator can grasp the grip 4 and safely perform the engine starting operation. Grip of the starter rope 3 tip in the vicinity position of the seat 1 extending from the recoil starter 2 of the engine E 4
A mobile agricultural machine equipped with the main clutch pedal 5 and the main clutch pedal 5 has a feature that a safe engine starting operation can be performed and can be suitably performed.
