Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention is based on the concept that a drawing marker is rotated around a longitudinal axis of a machine body from a working posture protruding laterally outward to a frame and a retracting posture retreating inside the machine body. A holding member is provided which is freely and stably stored and is switchable between a holding posture for holding the position of the drawing marker in the operating posture and a releasing posture for releasing the holding state, and the holding member is provided with a planting clutch. The present invention relates to a support structure for a drawing marker of a walking type rice transplanter, which is configured to be switched from the holding posture to the releasing posture in conjunction with the cutting operation.

[0002]

2. Description of the Related Art In the above described support structure for a drawing marker,
Conventionally, only in the on-operation state of the planting clutch,
Since the holding member is set in the marker holding posture, the drawing marker is always maintained in the stored posture in the disengaged state of the planting clutch.

[0003]

In the above-mentioned conventional structure, it is necessary to perform a drawing operation on a mud surface only during planting work. The operation is made easier. However, in the above conventional structure, for example,
At the beginning of the planting work, there is a drawback that it is not possible to cope with the work of drawing an index line on the mud surface along the outer periphery of the planting field before the planting work, and there is room for improvement. there were. The purpose of the present invention is to eliminate the above-mentioned disadvantages.

[0004]

According to a feature of the present invention, in the support structure for a drawing marker of a walk-behind rice transplanter described at the beginning, the drawing marker is maintained in the operating posture regardless of the releasing operation of the holding member. The lock member is provided so as to be switchable between a lock position to be locked and a release position to release the lock.

[0005]

When performing the drawing operation with the planting clutch in the disengaged state, after setting the drawing marker to the working posture, the locking member is switched to the locking posture, so that it is separate from the holding member interlocked with the planting clutch. , The drawing marker can be held in the working posture. Further, during the planting operation, the lock member is kept in the release position, so that the drawing marker can be switched in and out in conjunction with the planting clutch.

[0006]

Accordingly, it is possible to draw the first running index line at the start of the work in the disengaged state of the planting clutch, and the convenience in actual work is improved.

Embodiments will be described below with reference to the drawings. FIG.
Shows a walking rice transplanter. In this rice transplanter, an engine 1 and a transmission case 2 are arranged at the front of the fuselage, and a seedling planting section 3 is arranged at the rear. The left and right propulsion wheels 5 are supported through the steering wheel 6 toward the rear of the aircraft.
Is extended.

The seedling planting section 3 includes a seedling rest 8 which reciprocates left and right at a constant pitch with respect to the planting transmission case 7. A planting claw 9 for taking out and planting is provided. On both left and right side portions of the seedling planting section 3, a line serving as a running index of the next planting strip is placed on the mud surface with the planting work. Drawing markers 10, 10 for drawing are provided so as to be able to come and go. To elaborate,
As shown in FIGS. 1 and 3, the drawing markers 10, 10 protrude laterally outward around the longitudinal axis of the machine body from a planting transmission case 7 to a support frame 11 extending laterally outward. It is pivotally supported so that the posture can be freely switched between a working posture and a retracted posture which retreats to a vertical posture toward the inside of the machine, and is biased by a spring 12 toward the retracted posture. That is, the holding member 13 is pivotally supported by the support frame 11 on the support frame 11 at a position closer to the inside of the machine than the pivot point of the drawing marker 10, and the upper end of the holding member 13 and the drawing marker 10.
A tension spring 12 is stretched over a pin 14 protruding from a position distant from the pivot point of the pivot connection member 10a. The holding member 13 has a drawing marker 10.
Is formed with an engagement recess 15 in which the pin 14 engages and is positioned in a retracted posture, and the pin 14 engages with the engagement recess 15 to move the pin 14 to the storage position in the vertical posture. It is configured to be held in position. When the operating lever 17 connected via the linking rod 16 is manually operated, the drawing marker 10 is set to the action posture in which the drawing marker 10 falls down laterally and outwardly against the urging force of the spring 12. Is restricted to abut on the protruding locking portion 18 of the holding member 13 and is held in the operating position.

The holding member 13 is a transmission case 2
It is interposed in the power system toward the planting transmission case 7 from the side,
It is interlocked and linked via an operation wire 19 so as to rotate in conjunction with the operation of the planting clutch C for turning on and off the power transmission. The operation position holding state is set only when the clutch is engaged.

The return biasing force of the spring 12 comes into contact with the base end of the drawing marker 10 which is rotatable about the same axis as the pivot point of the holding member 13 and which is in the protruding action posture. Member 2 for restricting the position to that position against
0 is provided. When the lock member 20 is set in the lock operation posture, the drawing marker 10 can be maintained in the operation posture even during the disengagement operation of the planting clutch C. The lock member 20 is connected to the support frame 1.
1 and is freely rotatable with respect to 1. In the above-mentioned locking operation posture, it is locked by being stretched by the urging force of the spring 12, and during a normal planting operation, it is turned artificially and hangs down. By keeping it in a state (see FIG. 2),
The drawing marker 10 can be moved in and out in conjunction with the planting clutch C.
