Furthermore, as shown in FIG. 5, a horn 21 of the rice transplanter and the mascot lamp 19 are connected in parallel to a battery 20 mounted on the traveling vehicle body 1, and the horn 21 and the mascot lamp 19 are connected in parallel to the battery 20 mounted on the traveling vehicle body 1. A group of switches 9 is connected and grounded, and a position detection switch 11 is provided between the group of sensing switches 9 and the horn 21 in series therewith. In FIG. 5, reference numeral 22 is a reset switch, and 23 is a horn switch. In the embodiment configured as described above, the reset switch 22 is in the ON state during the planting work of the rice transplanter, and the seedling table 6 is moved in the left and right direction to place the seedlings in the center of its movement range. When the table 6 arrives, the position detection switch 11 is turned on, but when the seedlings on the table 6 do not require replenishment, all the sensing switches 9 are turned off, so the horn 21 does not work. When the number of seedlings in at least one of the partitioned parts of the seedling table 6 decreases and replenishment becomes necessary, a sensing switch 9 corresponding to that part is turned on, and a mascot lamp 19 is turned on. In this state, when the position detection switch 11 is turned on as described above, the horn 21 sounds each time the seedling platform 6 moves forward and backward in the left and right direction to issue an alarm.
When the rice transplanter is stopped by this alarm, the seedling platform 6 stops at the center of the range of movement in the left and right direction. Therefore, since the part where seedlings are replenished is relatively close to the seat 15, the worker can easily replenish spare seedlings from the reserve seedling platform 16 to the necessary part of the seedling platform 6 while the worker remains located on the seat 15. be able to. And seat 15
By horizontally rotating it by 90 degrees or more, the operator can easily replenish seedlings while sitting on the seat 15. In addition, when the sensing switch 9 is turned on and the machine comes close to the ridge when the mascot lamp 19 lights up, the machine stops traveling and replenishes the seedlings to the seedling platform 6 and transfers them to the preliminary seedling platform 16. Replenish seedlings. FIG. 6 shows a riding rice transplanter equipped with a device according to another embodiment of the invention. In FIG. 6, 24 is a clutch pedal provided on the traveling body 1 of the riding rice transplanter, and this pedal 24 has a plunger 26 of a solenoid mechanism 25 which is a means for stopping the rice transplanter.
