Description

[Detailed description of the invention] This invention creates an indicator line for the aircraft to run when planting the next row on the mud surface by plunging the tip into the mud surface or moving it while pressed against the mud surface. Regarding a line-drawing marker device for a rice transplanter, in which a line-drawing marker for forming a line is attached so that it can be switched between a retracted position and a line-drawing working position by vertical swinging, the purpose of the line-drawing marker device is to fix and hold the marker in the working position during line drawing. This makes it possible to reliably and accurately draw lines regardless of the hardness or unevenness of the mud surface, and even if there is a mechanism to fix and hold the working position, the working position of the marker and its retraction can be maintained. The aim is to make it easy to change postures by operating a single lever.

The line drawing marker device for a rice transplanter according to the present invention is provided between the marker 1 and the posture switching lever, and the fixing by the mechanism is released before the marker is switched to the retracted posture by the lever, and , characterized in that a linking mechanism is provided so that the position is fixed by the mechanism immediately after the operating position is switched by the lever.

That is, according to the present invention, only by continuously switching the posture switching lever of the line-drawing marker, when a line-drawing action is required, the marker can be switched to the working position and the desired action in that working position can be ensured. It is possible to perform both fixing and fixing at once, and when evacuation is necessary, the aforementioned unfixing and switching of the retracted posture can be performed at the same time. Therefore, by fixing the line-drawing marker in its working position, it is possible to always perform reliable and good line-drawing regardless of field conditions. It has become possible to change postures very easily and quickly using a single lever. Moreover, since you don't forget to fix or unfix the line marker, for example,
There is no risk of forgetting to release the fixation and forcibly switching the line drawing marker to the upward retracted position, which is also effective in preventing deformation and damage to the device.

Hereinafter, an embodiment of the present invention will be described based on the drawings. FIG. 1 shows a seedling planting device 11 that can simultaneously plant six seedlings at a time at the rear of a riding machine 10.
Fig. 2 shows a rice transplanter that can be freely switched between a working position for planting and a non-working position raised above the ground by swinging up and down. As a result, the line-drawing marker 1, which forms the aircraft running index line when planting the next row on the mud surface, is moved upward by swinging around the longitudinal axis a ₁ in a non-working position and in a working position protruding laterally and downward. This shows a line drawing marker device configured to be freely switchable.

The line drawing marker device is connected to the riding main machine 10.
By interlocking the swinging arm 5 that supports the marker 1 on the side of the vehicle so that the posture can be changed freely, and the operation lever 3 provided on the driver section 12 of the riding machine 10 via a wire 13, the marker 1 can be moved in the driver section 12. It is configured to be able to change the posture of 1.
Moreover, it has mechanisms 2 and 4 configured as follows.

One mechanism 2 is a swing axis of the swing arm 5.
A cam member 8 having a recess 7 that fixes the swing arm 5 in the working position by engaging with a protrusion 6 protruding from near the swing axis A ₁ in the direction of the swing axis A ₁ is attached to the swing arm. The cam member 8 is attached to the machine 10 so as to be able to freely switch between the engagement posture and the disengagement posture by swinging around _the axis _a2 parallel to the pivot axis a1 of the cam member 5. , an arcuate guide surface 9 is formed that is continuous with the engagement surface of the recess 7 and slides and guides the protrusion 6 when the swing arm 5 swings up and down, and the cam member 8 is engaged. A spring 14 is provided to bias the swing toward the working position, and the engagement between the protrusion 6 and the recess 7 fixes the marker 1 in the working position, and also allows the swinging arm 5 to swing to the working position. The projection 6 and the recess 7 are configured to automatically engage with each other.

The other mechanism 4 is swingable around an axis a ₁ parallel to the swing axis a ₁ of the swing arm 5 near the free end of the cam member 8, and the marker posture switching lever 3 A swinging lever 1 is interlocked and connected to this posture switching lever 3 via a wire 15 in a state in which it is pulled as it swings to the upward retracted position.
6 is provided between the swing lever 16 and the free end of the cam member 8, and the swing lever 16 swings in response to the pulling operation (swinging of the switching lever 3 toward the upward retracted position). At this time, when the cam member 8 is pressed and swung against the urging force so as to separate the recess 7 from the protrusion 8, and when the switching lever 3 is swung to the operating position, the cam member 8 and the oscillating A cam follower 17 and a cam surface 1 that automatically return the movable lever 16 to a state in which the recess 7 is engaged with the protrusion 6 by applying the biasing force described above.
8 is provided in the moving part of the switching lever 3 and the wire 13 that interlocks the switching lever 3 with the swinging arm 5,
At the initial stage of the switching operation from the working position to the upper retracted position, a flexible part 19 is provided to disconnect the switching lever 3 and the wire 13, and the concave portion 7 is removed from the protrusion 6, and the swing lever 16 is fixed in position by the cam member 8 as the switching lever 3 switches to the operating position.

The marker 1 is configured to be able to swing freely in the longitudinal direction with respect to the swing arm 5, and a buffer spring 20 is interposed in the middle of the marker 1 to absorb shock from the mud surface. be.

Further, the operation guide plate 21 of the switching lever 3 has a guide groove 22 for switching the marker 1 between the above-mentioned two positions, and a lever for switching the marker 1 beyond the upward retracted position to a substantially vertical position. 3
A groove 23 is formed to guide the movement.

Furthermore, the line drawing marker device is a
It is provided on both the left and right sides of 0.

24 in FIG. 1 is a preliminary seedling stand.

FIG. 5 shows that the swinging arm 5 and the swinging lever 16 are not individually linked to the switching lever 3 via the wires 13 and 15 as in the above embodiment, but are switched at one end. Lever 3
A single interlocking rod 25 is provided at the other end to interlock with the swinging arm 5 and the swinging lever 16, so that the above-mentioned interlocking is performed, and
Another embodiment is shown in which a similar accommodation 19' as in the embodiment is provided in the interlock between the swing arm 5 and the interlock rod 25.
