It is a switch that turns on and off in conjunction with the operation of (26e), so that the switch turns off when the clutches (29a), (29b), (29c), (29d), and (29e) are turned off. This switch is used as the abnormality detection switch (25a) to (2
5e) is provided in series as shown in FIG.

Explaining the operation of the above example, after the seedlings are stored in the seedling tank (11) and fertilizer is put into each of the hoppers (17a) to (17e), each rotating part is driven by the engine. The rice planting equipment (9) was pulled by and the seedling planting equipment (12a)
~ (12e) reciprocates left and right, and seedlings are divided from the seedling tank (11) and ground floats (13), (14a), (14
Plant on the soil surface prepared in b).

In addition, the fertilizer is gradually fed by the rotation of the feeding rolls of the feeding devices (18a) to (18e), and each fertilizer transfer pipe (19a)
~ (19e) Dropped into the inside. And the blower (2
The air blown in 2) is sent from the duct (23) to the air tank (21), and the transfer pipes (19a) to (24a) to (24e) to the transfer pipes (19a) to (24e). 19
The fertilizer is sent to e) and sent to the rear by this air and sent to the premises created by the groove making tools (20a) to (20e), and fertilizer is applied according to each of the above-mentioned seedling planting lines. become.

In this way, fertilization is performed at the same time as planting seedlings, but during the operation, at any one of the fertilizer applicators (16a) to (16e), the fertilizer feeding devices (18a) to (18e) and the transfer pipe (19a) to (1
9e) or the hoppers (17a) to (17e), when the fertilizer cannot be sent to the grooving tools (20a) to (20e) due to the fertilizer running out, the abnormality detectors (25a) to (25e) Will be detected. Then, the signal turns on the switch to excite the solenoid (32b), and the main clutch (32) is turned off. Therefore, the power transmission of the traveling / fertilizing device (16) and the rice transplanting device (9) is cut off, the rice transplanting work and the fertilizing work are stopped, and the traveling is stopped. Therefore, the driver should check the cause of the stop, eliminate the cause, and restart the work.

Next, when the planting work in the field is at the final stage and the ridges are to be planted, the planting width may be surplus if all planting lines are activated. At this time, the planting of a suitable number of rows was stopped in the previous step of planting the ridgeline, and all the seedling planting devices (12a) to (12e) were operated in the final ridgeline planting to leave the ridgeline unplanted. Try to lose it. When performing such work, the independent planting is performed to stop the seedling planting devices (12a) to (12e) on the ridge side by operating some of the appropriate sides of the ridge planting levers (31a) to (31e). Stop the attached clutches (30a) to (30e).

Then, in order to stop the fertilizer applicators (16a) to (16e) corresponding to the planting line by the stopped seedling planting tool, the rotation of the roll is stopped by the independent fertilizer application tools (26a) to (26e). Turn off the clutches (29a) to (29e).

Then, naturally, the fertilizers (16a) to (16e) in which the rotation of the roll has been stopped do not feed fertilizer to the groove making tools (20a) to (20e), so the abnormality detector (25a) to (25e)
Detects this, the switch is turned on and the solenoid (32b) is excited. At this time, the switch () is operated by the "off" operation of the clutches (29a) to (29e). Since the solenoid (32b) does not work because the solenoids (33a) to (33e) are turned off, the work is not stopped, and the work with reduced seedlings attached to the ridge can be surely performed.

Finally, when the feeding device (18) is described in detail, as shown in FIG. 5, the feeding roll (A) has a groove (34) for feeding the fertilizer and a shaft axis of the roll. It is provided in the direction of. Then, on the non-feeding side opposite to the rotation direction (a) of the roll (A), a brush (35) wider (L) than the groove width (l) is provided on the non-feeding side to prevent the fertilizer from spilling.
A flexible rubber plate (36) is integrally attached to the support frame of the brush (35) on the lower side of the brush. According to this structure, the groove (34) is surely crushed by the width of the brush (35) and the fertilizer does not spill in the non-rotating direction of the roll (A). Moreover, the roll (A) is a rubber plate (36)
Rotation of the roll (A) by the pressure resistance of the clutch (29a) ~
When it is turned off in (29e), it will surely be stopped at that position, and it will be possible to prevent the brush (35) from turning over.

(Function and Effect) As described above, the present invention has the following function and effect by the above-mentioned technical means.

In other words, when planting a ridge, when the number of planting lines is reduced and fractional planting is performed, the fertilizer application is applied to the part of the planting line that corresponds to the stop of the seedling planting device at that part. When the fertilizer is stopped so that the fertilizer is not applied to the non-planting strip portion, there is an effect that the seedling planting work can be continued substantially without the abnormality detector of the fertilizer application functioning.
