本考案は、田植機の苗植装置における苗載台に対する苗
マットの苗継ぎ装置に関するものである。[Detailed Description of the Invention] The present invention relates to a device for transferring seedling mats to a seedling platform in a seedling planting device of a rice transplanter.
従来、苗載台を有する苗植装置を走行機体に上下動自在

不安定になるばかりか、予備苗台が作業者の視界を大き
くさえぎることになるのであった。Conventionally, in a rice transplanter such as a riding type in which a seedling planting device having a seedling stand is connected to a traveling machine so as to be movable up and down, the spare seedling stand provided on the body side is tilted so as to approach the upper end of the seedling stand. Due to this, the construction is such that a spare seedling mat is added to the seedling stand on the spare seedling stand.
The height position of the seedling planting device relative to the traveling machine changes depending on the depth of the plow in the field (the difference in height between the plowing surface where the wheels touch the ground and the field surface), and therefore As the relative height positional relationship with the seedling stand attached to the planting device changes depending on the depth of the tiller, the relationship between the seedling transfer position from the reserve seedling stand to the seedling stand also changes, so it is always the same. It is not possible to transfer seedlings depending on the posture, and in addition, conventional spare seedling stands are brought closer to the seedling stand by lowering the side of the seedling stand, and are tilted in the same direction as the seedling stand, so the tiller is In order to ensure that the spare seedling stand is always located above the top of the seedling stand even when the water is deep, the spare seedling stand must be installed at a considerably high position, which raises the center of gravity of the aircraft and makes it unstable. Not only that, but the spare seedling stand ended up blocking the worker's view to a large extent.

5より先に後退勤するように構成して成るものである。Furthermore, the hydraulic cylinder 45 for raising and lowering the preliminary seedling stand and the hydraulic cylinder 47 for tilting are operated so that the hydraulic cylinder 47 for raising and lowering operates first.
The diameter of the lifting hydraulic cylinder 45 is set to be smaller than the diameter of the tilting hydraulic cylinder 47 so that the tilting hydraulic cylinder 47 operates after the stopper 48 of the upper link 39 in the parallel link mechanism 43 comes into contact with the lower link 40. While having a large configuration, a check valve 60 and a throttle 61 are provided in parallel in a circuit 59 leading from the hydraulic circuit 58 to the lifting hydraulic cylinder 45, so that the tilting hydraulic cylinder 47 is connected to the lifting hydraulic cylinder 4.
The system is configured so that the worker leaves work before 5.

次苗植される。During the rice planting work, a seedling mat is supplied onto the seedling platform 21, a spare seedling mat is placed on the preliminary seedling platform 36, and the seedling planting device 17 is lowered by operating the switching valve 52 to the lower position. Since the float 20 touches the field 62, the machine body 1 moves forward in this state and the seedling planting device 17 is driven. After being divided, seedlings are sequentially planted in the field scene 62.

行が停止して田植作業が中断される。Then, the hydraulic pressure supply from the hydraulic pump 16 to the switching valve 52 and the connection from the hydraulic cylinder 35 to the oil tank are cut off, so that from now on, it will not move up or down regardless of the switching valve 52, and will be locked so that it cannot be raised or lowered. Hydraulic pressure from a hydraulic pump 16 is sent to a hydraulic cylinder 12 that is linked to a hydraulic cylinder 10, which operates the hydraulic cylinder 12, rotating the clutch pedal 10 in the same direction as the foot pedal and turning the main clutch 11 off.
When it is set to F, the power transmission from the engine 4 to the transmission case 8 is cut off, the drive of the seedling planting device 17 and the running of the machine body 1 are stopped, and the rice planting work is interrupted.

The spare seedling mat on top of 6 can be stretched a little on the seedling stand 21.
Seedlings can be transferred to the top.

である。On the other hand, a hydraulic cylinder 45.4 for lifting and tilting the preliminary seedling stand
Since the circuit 58 to 7 is opened to the oil tank, the tilting hydraulic cylinder 47 is first retracted to return the reserve seedling stand 38 to a substantially horizontal position, and then the lifting hydraulic cylinder 45 is retracted to return the reserve The seedling stand 38 is lowered from the horizontal position by 1''l and placed on the support stand 37 of the machine body 1, completing the seedling succession work.
なお、予備苗台36は昇降傾斜台38に直接装着しても
良い。Note that the preliminary seedling stand 36 may be directly attached to the elevating and lowering slope table 38.

If it moves up and down in response to changes in the depth of the tiller, the rotational base end of the link mechanism 43 also moves up and down at the same time, and the linkage mechanism 43 swings up and down with the raised or lowered rotational base end as the center point. Since the preliminary seedling stand 36 is raised and lowered by the
The relative positional relationship with the seedling planting device 17 remains approximately constant regardless of changes in the height of the seedling planting device 17 with respect to the body 1.

って視界を向上できる効果を有する。Therefore, according to the present invention, the posture of transferring seedlings from the preliminary seedling stand to the seedling loading stand remains almost constant without being affected by the height position of the seedling planting device with respect to the machine body, and by extension, the variation in the depth of the plowing plate in the field. Since seedlings can be transferred in this position, there is no risk that seedlings will be difficult to transfer due to changes in posture due to the depth of the tiller, and seedlings can be transferred easily and quickly, and can be easily automated. Moreover, in the present invention, the preliminary seedling stand is raised and brought close to the upper end of the seedling stand by a link mechanism that rotates upward with the seedling planting device side as the rotation base. It can be installed at a location lower than the top of the seedling stand, so the center of gravity of the machine does not become high, improving the running stability of the rice transplanter, and the worker's view is less likely to be obstructed by the spare seedling stand. It has the effect of improving visibility.
