Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a line marker attachment device installed in a walk-behind rice transplanter.
A line is drawn on the soil surface on the unplanted land side, and a line marker is attached to the rice transplanter to maintain a constant row spacing when the rice transplanter is operated so that the left and right centers of the rice transplanter follow the line during turning operations. relates to a mounting device for the marker.

[Prior art]

The conventional line-drawing marker mounting structure involves pivoting a metal fitting on which the marker is attached to a support frame that protrudes to the left and right sides of the control position, and a spring is always applied to swing the marker upward. The metal fitting for preventing upward rotation of the metal fitting is provided so as to be adjustable in movement, and this metal fitting is operated by a planting clutch to adjust the upward rotational position of the line drawing marker. Note that if the line-drawing marker is rapidly rotated upwards by the spring from the line-drawing state, the mud adhering to the marker will jump upwards and splash mud on the worker, so be careful when planting seedlings. The marker is kept in a state where it does not rotate significantly when turning, etc., and the marker is raised greatly when driving on the road or when stored to prevent the marker from getting caught on foreign objects. 9. The lateral protrusion width of the marker is completely narrowed. The above-mentioned prior art measures were taken because of the need to do so.

[Problem that the invention seeks to solve]

Previously, the branch element was equipped with a metal fitting to stop the upward movement of the metal fitting on which the marker was attached, so that the stop position could be changed so that the entire stop position could be changed. This required a troublesome operation in which the attachments had to be changed accordingly.

is connected to the second metal fitting α9, and the clutch is connected to the second metal fitting α9.
When operating from the "ON" state to the "OFF" state, wire 02 is pulled.

In the above specific configuration, the downward movement position holding S composition is the locking pin of the second metal fitting α9 and the inner end side outer peripheral surface (A) of the first metal fitting α0.
It consists of a part and a spring. Further, the middle movement position holding mechanism CB) is constituted by a locking pin (2) on the first metal fitting αG side and a stopper recess (b) and a barb @ on the second metal fitting α9 side. Furthermore, the release mechanism (q is the second metal fitting αg

To explain the configuration on the upper side, when planting seedlings,
Move the marker α81i down using the control lever (5) on the unplanted area side. That is, operate the lever @ all in the direction of the arrow (c). At this time, turn on the seedling planting clutch and operate it later.

Then, the first metal fitting (16) is rotated downward via the rod @, and at this time, the peripheral surface (A) pushes the pin 4 and the second metal fitting (16) is rotated downward.
Temporarily push the metal fitting 09 in the direction of the arrow ) against the spring catch, and the first metal fitting (16) in FIG. Then, the first metal fitting qG is no longer regulated by the pin and cannot be swung up. 1. At this time, the tip of the marker part (18a) plunges into the soil on the unplanted land side, and a line is drawn by the movement of the rice transplanter.

Next, when the seedling planting work is carried out near the ridge on the 6t1 side and the machine turns, the seedling planting side clutch is operated to "off". Then, the wire 132 is pulled, and the second metal fitting α9 is rotated in the direction of the arrow ( ) against the spring rock. Then, the bottle (A) and the peripheral surface (A) of the first metal fitting αG come off, and the first metal fitting α
G rotates upward due to the tension of the spring.

Then, the locking pin (to) installed on the first metal fitting αG contacts the locking recess (b) of the second metal fitting α and is held in the intermediate movement position.

At this time, the marker (181 does not move up significantly, the soil surface edge 1/1 II φ, h mark 7 r hundred (C1 only 9) force;
In the unlikely event that it is stopped, there is no chance that it will be stopped.

After turning in this state, turn the seedling planting lever to "on" again, and lower the marker operation lever,
By aligning the center of the rice transplanter with the line marked on the soil surface in the previous step, the row spacing will be maintained at a constant level and the seedlings will be planted.

Next, when driving on the road, on a ridge, or when storing, the seedling planting clutch is naturally in the ``disengaged'' position, and the first metal fitting Ql19 is locked with the locking pin (c). In this state, the marker portion (18a
) may get caught on stones, road grass, or ridges on the road because they are not raised high from the ground. In such a case, the operator pulls the handle (A) backward against the spring D, and as shown in the imaginary line in Fig. 3, the second metal fitting α9 is fully moved to secure the rear end of the locking pin (2). When removed, the first metal fitting αυ spring rotates as shown in the imaginary line shown in FIG. 2, and the marker U& is swung upwards.

Therefore, by doing this, the marker αa will not get caught on foreign objects or ridges on the road surface, and the situation that could cause damage to the marker 0& can be eliminated, and the left and right width of the marker will be reduced when it is stored. It is narrow and does not require a large storage space,
It becomes easier to store.

Incidentally, in the upper embodiment, the marker α81t cannot be set to move downward unless the seedling planting clutch is turned on, but when the clutch operation lever is turned from off to on,
Alternatively, pull the wire 132'c in the middle of switching from "on" to "off", and connect the arm c331zc to the clutch lever (support) in Fig. 5 so that the wire 04 is loosened after the "on" and "off" operations. In the middle of the rotation of this arm trowel, an engagement rotation arm (to) is provided that is hooked and rotated by this arm Q during reciprocating rotation, and with this, the wire Oa can be pulled even when rotated to either side. , and then you can relax. Furthermore, as shown in FIG. 6, the first metal fitting αG
The gold pulling spring 05 may be specially provided. in this case,
The pulling force of the second metal fitting can be weakened by the tension of the spring.
Clutch lever can be operated easily.

[Achieving Effect 4] Since the present invention has the above-described structure, it is easy to operate the marker up and down during seedling planting, and the labor required for the operation can be reduced, and the muddy soil of the marker can be reduced. This reduces the amount of mud splashing onto the operator, and when driving on the road or over a ridge, the marker can be moved upwards to prevent damage to the marker. Also, when stored, the left and right opening of the marker is narrow. It has the effect of being easy to store and easy to store, and it is extremely easy to switch between the above operations, and when planting seedlings, when turning during work, the marker is automatically stopped halfway by the turning operation. When driving on the road, the second metal fitting itself can be operated to move the marker higher and higher, and the structure itself can be simplified compared to conventional ones, providing a unique effect.
