Description

DETAILED DESCRIPTION OF THE INVENTION Komyo Komei is concerned with a switching device for wire drawing 7-ka, which is used in IJI transplanters.

When the rice transplanter is run 11 times back in the field to plant seedlings, mark the field on the side of it while the rice transplanter is moving forward, and the next time the rice transplanter goes back, mark the field as above. Mark the direction of travel of Ill 4Fi m,
It is necessary to adjust the row spacing of seedlings after planting and the linearity of the rows. Based on the above needs! 11 The rice transplanter is equipped with a line marker, and in this type of rice transplanter, for example, as seen in Japanese Patent Application Laid-Open No. 1983 'G3307 S', when the rice transplanter rotates, A method has been proposed in which the left and right markers are switched between active and non-active positions by operating the lift lever.

By this, when it is a turn-around, the marker will always be used to mark the next turn () on the side where Yuzui 1 () is not
It became possible to draw guide lines for the 4m aircraft, and it became possible to do the errands automatically.

However, when replenishing seedlings in the seedling-planting work using a single-port transplanter, even if the rotation operation is not performed, the first part of the planting Ge is often ref[ed] and re-supplied to the seedling stand. In this case, automatic switching becomes inconvenient.

The present invention has been made based on the above circumstances, and is capable of automatically switching between the f1 and Ij parts of the same machine when lifting the f1 and Ij parts at the same time. However, when lifting the rice transplanter's GJ section while the rice transplanter is going straight, the marker cannot be switched.However, we are trying to provide marker switching equipment for the rice transplanter.

For this purpose, Kikomei placed a mark (=i?l) on the field to guide the planting machine, and the effect J5J,
Move the marker to the non-operating position and place the marker at 1-1 on the machine, and press the lift lever to move the planting part downward.
Turn the planting lever (-6) to switch the transmission in the planting part (-6).
1-In the case where the operating position of the marker ()ii on the right side is changed by operating the F+-lever as described above, soil, ;'I11!
In addition to installing a marker switching element on the lift lever guide that switches the lift lever from lift 1 to side 4CvJ,
The present invention is characterized in that a means for avoiding the operation of the recording force switching element is provided.

Hereinafter, one embodiment of the present invention will be explained in detail with reference to the drawings.
At its rear part, a -C planting part 3 is immovably connected to via a link mechanism 2, and a driven lever 0 is connected to a screw of a hydraulic cylinder 4 fixed to the body 1 during running. The free ends are connected, and when the screws 1 to 5 extend outward from the hydraulic cylinder 4, the link mechanism 2 operates via the driven lever 6, and the screw 4 = J section 3 is moved upward. It is designed to allow In addition, the bases of markers 7.8 are rotatably attached to the left and right sides of the planting part 1 3, and near the l nadle of the traveling vehicle body 1, there is a marker for actuating or stopping the planting part 3. A planting lever 9 and a lift lever 1 that switches the supply and discharge of pressure oil to the hydraulic cylinder 4 in order to move the planting part up and down.
0 is arranged respectively. And the above marker 7
and 8 are operated by solenoids 11 and 12, respectively, and switches 13 and 14 for energizing each of the solenoids 11 and 12 are operated by a switch 16 via a flip-flop circuit 15. The configuration is such that switch A-J3 and switch A-off are alternately turned on. The switch 1G is a push button type limit switch [48], and is arranged in relation to the ref l-lever 10.

In the first embodiment, the guide 17 of the lift lever 10 shown in FIG.
Guide slit 1- from a to ascending set position 11i17b
is divided into two parts, one of which is I' M v
The above-mentioned switch 16 is arranged corresponding to the illumination 7b, and the push button 16a is pressed with the lift lever 10 to release the switch A.

Therefore, by operating the lift lever 1() and holding the lever 10. to the side where the switch 16 is located, the switch 16 turns on and the markers 7 and 8 are switched to the switching operation 1. "The energization switching of the solenoids 11, J, and 12 is achieved, but if you bring the lift lever 10 to the side where the switch 1G is not located, there is no switch switching. Therefore, when replenishing seedlings, etc. When operating the lever 10, hold the lever 10 to the side where the switch 16 is not located.

In the second embodiment, as shown in Figs. 5 and 6, there is a forward and backward guide shape C in which the guide 11 of the lit lever 10 is arranged with the sweets y16, but in addition to this, the guide 18 of the 4171fi lever 9 is Yes, here is the "off" of the planting lever.
A puller 19 extends on the path to the operating set position. The number control 19 is pivotally supported and extends to the push button IGa of the switch 16.

Then, when pressing the ( )lυ control device 9 with the planting lever 9 to set it to the "OFF" operating position, the G
The J/υ control device 9 is removed from one side of the push button 16a.

Therefore, when the lift lever 10 is moved to the 10th position, the push button is pressed with the lever 10 to perform switching, but when the planting lever 9 is not operated, the lift lever 19 is moved above the push button 16a. Since the operation of the lever 10 is restrained, the operation to the riff 1 is achieved, but the push button 16a remains pressed and no switching is performed. For this reason, the number stop 19 is lightly supported by a spring, and its pivot point is on the operating line of the lift lever 10.

In this way, even if the lift lever 10 is operated, the marker switching operation will not occur unless the planting section is stopped by operating the planting 4 lever 〇! There isn't.

For this reason, during normal companionship, the marker is automatically switched in conjunction with the operation of the rotating shaft lever, but it is
Even if tJ, 4ti4 rim section lift is performed when replenishing seedlings during the 16th running process, the marker switching is canceled.

Although the switch 16 is used as the marker switching path r in the above embodiment, it goes without saying that a conventional mechanical element may also be used.

The present invention thus relates to the riff [lever].
7- In addition to arranging the switching cable end, if necessary, the operation of the marker switching element is avoided and the levers can be operated in this state, so normally, the rotation of the Ell transplanter is Sometimes planting in the middle of GJ (Pub Lift's poem ?-Although it has the advantage of automatically switching left and right power, it also has the advantage of being able to replenish seedlings, etc.) By lifting the G) section, switching of markers can be avoided, and the left and right 7-wheels can always be operated correctly, which is an excellent IC effect.
