(Seedling stand 17
A center switch C8 is provided on the arm 20, etc., which turns on when the seedling table and the spare seedling stand 28 are aligned in the horizontal direction.
The center switch C8 is connected to the upper and lower limit switches L.
S1゜Connect in series with LS2, and when manual/automatic changeover switch SW1 is ON and LSI, LS2, and C8 are all ON, relay R is activated, and solenoid coil S
The CI is connected to ON, and this drives the solenoid coil SC1 to operate the switching valve 41 to raise and tilt the spare seedling stand 28 toward the seedling stand 17, while turning off the main clutch 10 and turning the machine off. A recovery switch R8 is provided in series with the solenoid coil SC1, and when the clutch pedal 9 is depressed, the recovery switch R8 is turned OFF, and the relay R is turned OFF.

のち圃場面に順次苗植される。In this configuration, during rice planting work, the seedling mat 53 is supplied onto the seedling platform 11, a spare seedling mat is placed on the preliminary seedling platform 28, and the seedling transplanting device 13 is operated by operating the switching valve 40 to the lowered position. By descending, the float 16
Since the machine 1 touches the ground on the field, in this state, by moving the machine 1 forward and driving the seedling planting device 13, the seedling mat on the seedling platform 17 is divided into individual plants by the seedling planting mechanism 14, and then placed in the field. Seedlings are planted sequentially on the surface.

植作業が中断される。In this way, if any one of the slot switches LS2 is ON and the corresponding LSl of the 53 seedling mats is ON, seedling splicing work is required, so the horizontally moving seedling platform 17 is used as a spare seedling platform. 28 (center position shown in Figure 2), the center switch C
8 is turned ON, the relay R is operated to drive the switching valve 41 via the solenoid coil SC1, and the hydraulic pump 12 is activated.
Since the hydraulic pressure supply from to the switching valve 40 and the private lodging from the hydraulic cylinder 27 to the oil tank are cut, from now on, the switching valve 4
0, the seedling platform 11 does not move up or down and is locked so that it cannot be moved up or down. On the other hand, the hydraulic pressure from the hydraulic pump 12 is sent to the hydraulic cylinder 11 that is linked to the clutch petal 9, and the hydraulic cylinder 11 is activated. The main clutch 10 is turned OFF by rotating in the same direction as the foot pedal.
The power transmission from the engine 4 to the transmission case 8 is cut off, the drive of the seedling planting device 13 and the movement of the machine body 1 are stopped, and the rice planting work is interrupted.

する。At the same time, hydraulic pressure from the hydraulic pump 12 is sent to the hydraulic cylinders 34 and 36 for raising and lowering the preliminary seedling stand, and the raising and lowering hydraulic cylinders 34 are first operated to protrude, and the lifting and lowering slope table 3
0 rises from the horizontal position, and on the way up, lifts the preliminary seedling stand 28 from the horizontal position 1\, and lifts the upper link 31
The stopper 37 of is raised at 1 when it comes into contact with the lower link 32.

継ぎが行なわれる。Next, the tilting hydraulic cylinder 36 is operated to project, and the elevating and lowering ramp 30 is tilted by the casing that contacts the tilt stopper 39, and the preliminary seedling stand 28 on its upper surface approaches the seedling loading table 17, and the seedling loading table is closed. Since it is tilted so as to be approximately parallel to 11 and with the same horizontal direction, the spare seedling mat on the preliminary seedling stand 28 can be moved onto the seedling stand 17 by sliding it slightly, and the seedlings can be transferred. It is done.

的に切れて予備苗台が不必要に上昇動しないのである。Additionally, when the lower part of the seedling mat 53 is floating above the seedling stand 17, the lower limit switch L S 2 of the relevant part is activated.
turns ON, and the corresponding lamp PL2 lights up. However, if the length of the seedling mat 53 is long enough, the upper limit switch LSI remains OFF, so the seedling stand 17
Even if the center switch C8 is turned on when the seedling stand reaches the center position, the relay R is not activated, so the main clutch 10 is automatically disengaged and the spare seedling stand does not move up unnecessarily.

植作業を能率良く行える効果を有する。In short, according to the present invention, a seedling pine detection device that operates independently is provided for each side-by-side seedling pine placement portion of the inclined seedling platform at appropriate intervals along the vertical feeding direction of the seedling pine. , Both the upper and lower seedling pine detection devices are ON.
By this, the necessary time for seedling succession is detected, and at this time, in conjunction with the lateral direction coincidence detection device for the seedling stand with respect to the spare seedling stand, the main clutch for driving the machine advancement and the seedling planting device is turned off.
The auxiliary seedling bed is automatically moved toward the upper end of the seedling stand when the main clutch is turned off, thereby reducing the movement of the auxiliary seedling mat. In addition, once the preliminary seedling transfer work is completed, the return of the preliminary seedling stand and the movement of the machine can be performed with a single operation, which greatly reduces the number of operations before and after seedling transfer, making rice transplanting work more efficient. have
