The fertilizer run-out sensor 103 provided in the fertilizer tank 41 is mounted on the lower slope of the tank 41 and configured to receive fertilizer pressure and perform sensing. In order to position the fertilizer tank 41 as far forward as possible in a balance relationship, the wall surface of the tank inner surface is configured to have an inclination that the front side becomes gentle, and the sensor 103 is provided so as to be attached to this gentle inclined surface. Has been. In this way, even if the amount of fertilizer becomes small, the sensor can sufficiently receive the fertilizer pressure, and it is possible to accurately detect out of fertilizer. It goes without saying that the sensor 103 is connected to a buzzer or a warning light. Further, the air tank 4 is provided in front of the sensor 103.
Since the structure is such that 7b extends to the position,
The sensor portion is sufficiently protected, and it is possible to prevent a situation in which a foreign substance collides with the sensor portion unexpectedly and is damaged, or the detection performance is changed. A fertilizer clogging indicator 104 is provided on the rear plate 84 rotatably provided on the fertilizer application frame 40.
On the rear surface of the grooving device 44, the fertilizer is clogged between the conductive rod 105 and the wall surface of the grooving device 44, which is appropriately separated from the front surface of the inner wall of the grooving device 44, or the muddy water entering the grooving device is fertilized. When it becomes a state where the fertilizer is fully melted and is clogged, it is detected that electricity flows between them without difficulty and this is displayed. According to the fertilizer clogging detection mechanism 106, accurate detection can be performed with little influence of mud or mud in paddy fields. Reference numeral 107 denotes an adjusting device for the detection mechanism 106, which adjusts the detection sensitivity according to the field. That is, by adjusting the electric conduction resistance, when the mud in the field at the time when the fertilizer has not been sprinkled yet has sufficient electric conductivity, the detection mechanism works to prevent false alarm.

Next, the operation of the above example will be described. First, when a large amount of spare seedlings are mounted on the side of the riding type traveling vehicle body 1, the spare seedling placement device 3 is used as shown in FIGS. 1 and 2.
1 is mounted on each of the front and rear brackets 29a and 29b to mount a large amount of seedlings. When it is not necessary to mount a large amount of seedlings, it is advisable to remove the preliminary seedling placement devices 31 on both front sides or both rear sides.

In this state, seedlings are mounted on the seedling mounting table 16 of the rice planting work machine 14, granular fertilizers are stored in the fertilizer tanks 41, and the transmission rotary parts are moved while the riding type traveling vehicle body 1 is moved forward. When driven, the seedling placing table 16 reciprocates left and right, and the seedlings are delivered to the lower end side thereof. Then, the transplanting tool 18 swings with the rotation of the rotating case 17, and the transplanting claws move in a vertically long closed loop-shaped transplantation locus, thereby dividing and holding one seedling per one plant from the seedling mounting table 16. Seedlings are planted on the soil surface of the paddy field leveled by the leveling floats 20 and 21.

On the other hand, a connecting member A (crank 97, drive rod 96) whose base is connected to the fertilizer drive shaft 102 which is transmitted from the planting device drive shaft 98 for driving the rotating case 17 through gears 99, 101, 102a.・ Operating lever 95 ・
Ratchet mechanism 94, fertilizer driven shaft 53, clutch mechanism 5
In 4), the feeding roll 46 of each fertilizer feeding device 42 is rotationally transmitted in a fixed direction. For this reason, when the clutch mechanism 54 is set to “ON”, the feeding roll 46 is rotated, and the fertilizer is fed from the fertilizer tank 41 and discharged to the lower funnel 74, flows down in the transfer pipe 43, and flows into the groove pipe 44. Is discharged to the opening. At this time, the compressed air from the blower 47a is accumulated in the air tank 47b, and this high-pressure air is blown into the transfer pipe 43 below the funnel 74 through the wind conduit 48 to forcibly produce the fertilizer flowing down in the transfer pipe 43. The fertilizer sprinkled in the groove opened by the groover 44 in this way is accurately transferred to the groove tool 44. Then, the groove is backfilled by the soil cover plate 108 and buried under the soil surface. .

In this way, the seedling planting work and the fertilizing work are carried out at the same time. To adjust the feeding amount of each fertilizer feeding device 42, the gear 90 is moved to disengage from the gear 51. It is advisable to rotate the gear 51 in the forward or reverse direction to move the gear 51 left and right with the screw of the cylinder shaft 50, thereby moving and adjusting the payout adjusting roll 46b.
Further, in order to adjust the feeding amount of each fertilizer feeding device 42 all at once, when the lever 88 rotates the planting device drive shaft 89 forward and backward, the gear 90 is rotated by the gear 90, and the same adjustment as described above can be performed.

When the fertilizer in the fertilizer tank 41 is discharged after the work is completed, the fertilizer take-out trough 61 is opened as shown by the phantom line in FIG. When the member 66 is pulled out, the fertilizer in the tank 41 is received by the fertilizer take-out trough 61 and discharged as it is to the outside on the rear side. The fertilizer discharged should be received in a container as appropriate. In addition, when cleaning the water supply roll 46 of the fertilizer supply device 42 and other appropriate parts, and draining water after cleaning, removing the blower 47a and blowing the wind can easily perform cleaning and drainage.

In particular, the fertilizer drive shaft 102, which receives the rotational power from the planting device drive shaft 98 at the rear of the sub power transmission case 15b and rotates, is located behind the planting device drive shaft 98 at the rear of the sub power transmission case 15b. Since the fertilizer drive shaft 102 is provided so as to project from the side wall and the fertilizer feeding device 42 of the fertilizer applying device 39 is driven via the connecting member A, a special drive system for driving the fertilizer feeding device 42 is provided. It is not necessary to arrange the fertilizer drive shaft from the side of the riding type traveling vehicle body 1 and simply receives the rotational power from the planting device drive shaft 98 that drives and rotates the planting device 19 provided in the rear portion of the auxiliary transmission case 15b to rotate the fertilizer application shaft. It can be driven by 102, the drive to the fertilizer applicator 39 and the structure of the machine are very simple and compact,
However, since the fertilizer application drive shaft 102 and the fertilizer application device 39 are arranged relatively close to each other, the machine body structure is simple and appropriate drive can be performed.

Further, since the connecting portion between the fertilizing drive shaft 102 and the connecting member A is arranged between the side wall of the auxiliary transmission case 15b and the rotation locus of the rotating case 17 and above the leveling floats 20 and 21, The connecting portion between the fertilizer application shaft 102 and the connecting member A is located in the space surrounded by the rotating case 17 that rotates with the side wall of the sub transmission case 15b and the leveling floats 20 and 21, and is scraped up by the transplant tool 18. It becomes difficult for the muddy soil and muddy water splashed from the leveled floats 20 and 21 to directly come into contact therewith, and the operation can be performed smoothly for a long period of time, and good fertilization work can be performed.
