Abstract

PURPOSE:To change over and maintain the rotation of a prime mover automatically to low speed for reducing engine sound and fuel consumption by holding a main clutch at the disengaged condition with a pedal being pedalled. CONSTITUTION:When a seeding planting operation its wanted to stop, the front end side of a pedal 50 is pedalled to depress an arm 52 and put a lock claw 55 into a hole 51 in a pedal mount 13 while a force is applied to the rear end side to rotate the pedal 50. Then, the lock claw 55 is put into an engaging hole 59 provided in a fitting 58 for an engaging member 57 so that the end of the claw engages the fitting 58 to be held by it. That is, the downward movement of the arm 52 pivots a lever 49 of a main clutch so that the main clutch is held at the disengaged condition. On the other hand, an inner wire 62b of a release wire is pulled with pivotal lock position of the lock claw 55 to pivot a throttle lever and change over a prime mover to low speed.

Description

[Detailed Description of the Invention] This invention relates to a stop operation device for a riding agricultural machine, and conventionally, a rice transplanter, sowing machine, etc. was attached to a traction vehicle body on which a prime mover is mounted. In a work machine, the main clutch, which simultaneously turns on and off the power transmission of the running part of the production vehicle body and the power transmission of the working parts such as the rice transplanter part and the sowing machine part, is disengaged by pressing the foot pedal, and the main clutch is left in this disengaged state. There was one that was designed to hold the clutch in place, but even if the main clutch was turned off, the engine rotation would not slow down and the engine would remain at the same output as when working. If the noise was louder than ever, fuel consumption would remain the same, so the driver often had to move the throttle lever toward lower speeds one after the other.

This invention eliminates the above-mentioned drawbacks by keeping the rotation of the prime mover at a low speed when the main clutch is disengaged and held for a certain period of time without having to perform the above-mentioned troublesome operations. It is an object of the present invention to realize a stop operation device for a riding agricultural machine. 8 To this end, the present invention has taken the following technical measures.

to maintain the rotation in an appropriate state.

Then, the input shaft (A) is transmitted and rotated from the input pulley (B) via the main clutch (To), and the front and rear wheels (5), (5), (7), ( 7) is transmitted and rotated to propel the tractor body (1), and at the same time, the rice transplanting device θ side is also transmitted so that the seedling planting device 0 divides one seedling in the clean tank 0. Then, seedling planting work is carried out,
When the number of seedlings in the seedling tank 0η is low and you need to replenish the seedlings, or if you want to temporarily stop planting seedlings for reasons related to the pond, step on the front side of the petal (T) and press the arm (52).
Press down and insert the lock claw (55) into the hole (5L) of footrest 03.
Press down inward and apply force to the rear end of the petal handle to swing the petal (7) in the direction of the arrow. Then,

), and the tips of the claws engage with the two walls of the metal fitting (58) and are held in that state.

That is, the downward movement of the arm (52) causes the lever 4 of the main clutch OC to
1 will be rotated in the direction of arrow P), and as a result, the main clutch will be disengaged and this state will be maintained. On the other hand, due to the rotational locking position of the lock claw (55), the inner wire (62b) of the release wire (62)
is pulled, the throttle lever α is rotated in the opposite direction of the arrow (c), and the prime mover (4) is switched to low speed.

Therefore, the engine noise is lowered and the amount used by each furnace is reduced.

In this way, while the seedling planting work is temporarily stopped, work such as feeding the seedlings from the preliminary seedling stand (B) to the seedling tank α force is carried out, and then when the work is resumed, the petal □□□ is If you disengage the lock claw (55) and the metal fitting (58) while stepping forward and take your foot off the petalu, the arm (52) will move upward due to the return force of the gene (60), and the main launch弼 is restored to its previous working state and becomes a human, and the inner wire (62b) for pushing and pulling the throttle lever 04) is also restored.
) will return it to its original state.

In addition, if the inner wires (6p, b) are not used for both pushing and pulling, the operator must set the throttle wire to 0.
It is recommended to operate 4) when restarting work.

Further, if the attachment position of the inner wire (62b) and the lock pawl (55) can be changed as shown in FIG. 5, it is convenient because the set position of the throttle lever 04) can be maintained properly.

So, is this invention F? Because of the configuration described in IJ, the main clutch can be held in the disengaged state by pressing the pedal, and when the main clutch is held in the disengaged state, the rotation of the prime mover is automatically switched to a low speed and maintained. Therefore, the engine noise is reduced and the fuel consumption is also reduced.
