Description

TECHNICAL FIELD The present invention relates to an agricultural work machine such as a rice transplanter equipped with a line drawing marker for drawing a line, which serves as a mark for a steering operation in the next step, on the soil surface.

[Prior art and problems to be solved by the invention]

Generally, agricultural work machines such as rice transplanters are equipped with a line drawing marker for drawing a line on the soil surface, which serves as a mark for the operation operation in the next step. If it is provided on the rear side of the seat, it is not possible to confirm whether or not the line drawing marker is switched to the line drawing working state without looking back. In addition, even when looking back, it is often the case that the planting condition just after the current is distracted, and it is difficult to notice whether or not the line marker is drawing on the soil in the next process. Therefore, if the user forgets to switch the wire drawing marker to the wire drawing working state, it is difficult to notice this and the seedling planting work is likely to proceed without wire drawing.

Therefore, as shown in JP-A-56-26109,
A technology has been developed that is equipped with an automatic switching mechanism that automatically switches the unmarked side drawing marker to the drawing operation state during turning. In the case of implementing this technique, if the line drawing marker is switched to the line drawing action state when the rice transplanter is lowered during non-planting work, it will be an obstacle when lowering the rice transplanter and storing it in a warehouse etc. Therefore, a switch is provided to switch the automatic drawing marker switching mechanism between a state in which it automatically operates and a state in which it does not automatically operate. Then, this switch only needs to be switched to a state in which it automatically operates when starting work, and does not need to be operated after starting work. Therefore, if this switch is operated properly at the start of work, it will be very convenient because the automatic switching mechanism of the wire drawing marker will be activated, but on the other hand, it will only be operated once after entering the paddy field. Since it is a thing, it is easy to forget the operation, and it is not something that can be easily forgotten by a skilled person, such as an operation performed every turn.

In addition, if you forget to operate the switch of the automatic switching mechanism of the above-mentioned wire drawing marker, you will work without drawing in the first stroke, turn and enter the next stroke,
Only when you see that the line is not drawn on the process, you will notice that you forgot to operate the switch.

Therefore, the problem to be solved by the present invention is to provide an automatic switching mechanism for bringing the unplanted side drawing marker into a drawing working state, and a switch for switching the automatic switching mechanism between a state of automatically operating and a state of not automatically operating. That is, when entering the paddy field and starting the rice transplanting work, it is possible to surely switch the automatic switching mechanism of the wire drawing marker to the automatically operating state.

[Means for solving problems]

In order to solve the above problems, the present invention is an agricultural work machine provided with line drawing markers 26, 26 on the left and right sides behind the cockpit 10 for drawing a line, which serves as a mark for a steering operation in the next stroke, on the soil surface. In, at the time of turning, provided with an automatic switching mechanism that automatically switches the non-planted side drawing marker 26 to a drawing working state, and a switch MSW that switches the automatic switching mechanism between an automatically operating state and an automatic operating state, The agricultural working machine is characterized in that a warning means is provided to warn that the work has started even though the switch MSW has not switched to a state in which the automatic switching mechanism is automatically operated.

[Operation and effect of the invention]

When the agricultural working machine configured as described above enters the paddy field and starts working, the switch of the automatic switching mechanism of the wire drawing marker is switched and operated. Then, after that, the operation of the automatic switching mechanism automatically switches the drawing marker on the unplanted side to the drawing operation state at the time of turning, and the switching operation of the drawing marker for each turning becomes unnecessary. Also, if you forget to operate the switch of the automatic switching mechanism at the start of work, if you start the work with the operation forgotten, the warning means will warn that state, so the automatic switching mechanism surely, It can be switched to the automatic operation state. Further, during non-working, if the switch of the automatic switching mechanism is switched to a state where it does not operate automatically, the wire drawing marker will not switch to the wire drawing working state, so the wire drawing marker becomes an obstacle when it is stored in a warehouse or the like. Things will disappear.
