Thus, the operation of the rotating case 17 and the implant 18 is not hindered.

The transmission of the fertilizer application driven shaft 53 is performed by mounting a ratchet mechanism 94 as a one-way rotation mechanism on the fertilizer application driven shaft 53 on the fertilizer application driven shaft 53, and operating the lever 95 via a driving rod 96. The auxiliary transmission case 15b is connected to a crank 97 provided to be rotated by a fertilizing drive shaft 102 protruding to the side of the rear end of the sub transmission case 15b. The rotation of the crank 97 causes the lever 95 to swing up and down. The fertilizer driven shaft 53 is linked by a link mechanism so as to be transmitted and rotated in a certain direction.

The crank 97 is connected to the rotating case 17.
When the spur gear 99 is attached to the drive shaft 98 of the planting device, and the fertilizer transmission case 100 is attached to the rear end of the auxiliary transmission case 15b instead of the lid attached when the fertilizer application device 39 is not attached, the fertilizer transmission case 100 A driven intermediate spur gear 101 previously mounted on the inside meshes with the spur gear 99, and a fertilizer drive shaft 102 to which a gear 102 a meshing with the driven intermediate spur gear 101 is mounted is rotated, and a crank 97 mounted on the fertilizer drive shaft 102 is rotated.

It is arranged at a slightly higher position in the rear direction of the bearing case part (R) that wraps the bearing case. When the crank 97 is disposed at such a position, it is extremely effective because muddy soil or muddy water is unlikely to be applied to the crank 97.

A fertilizer out sensor 103 provided in the fertilizer tank 41 is mounted on a lower slope in the tank 41, and is configured to receive a fertilizer pressure to perform sensing. In order to position the fertilizer tank 41 forward as much as possible in relation to balance, the wall surface of the tank inner surface is configured to have a slope with the front side becoming gentle, and the sensor-103 is made to be stuck on the gentle slope. Is provided. 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. The sensor 103 is a buzzer.
Or it goes without saying that it is connected to a warning light. The air tank 4 is located in front of the sensor 103.
Since the sensor is extended to the position where the sensor 7 is located, the sensor portion is sufficiently protected, and a situation in which a foreign object unexpectedly collides with the sensor portion and is damaged or the detection performance is changed is prevented. it can. 104 is a fertilizer clogging indicator,
A fertilizer is mounted between the conductive rod 105 mounted on the back surface of the rear plate 84 rotatably provided on the fertilizer application frame 40 and suspended at a suitable distance from the front surface of the inner wall of the groove generator 44, and the wall of the groove generator 44. When the clogging occurs, or when the fertilizer is sufficiently clogged with the muddy water that enters the channel generator, the flow of electricity between the two is detected without difficulty, and this is displayed.
In addition, according to the fertilizer clogging detection mechanism 106, accurate detection can be performed almost without being affected by muddy soil or muddy water in a paddy field. Reference numeral 107 denotes an adjustment 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 muddy water in the field at the time when the fertilizer has not been scattered yet has sufficient electric conductivity, the detection mechanism operates to prevent false alarm.

Next, the operation of the above example will be described. First, when a large number of spare seedlings are to be mounted on the riding type traveling vehicle body 1 side, as shown in FIGS.
1 is mounted on 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, the spare seedling placement devices 31 on both front sides or both rear sides may be removed.

In this state, seedlings are mounted on the seedling table 16 of the rice transplanting machine 14 and granular fertilizers are stored in the fertilizer tanks 41. When driven, the seedling mounting table 16 reciprocates left and right, and the seedlings are fed to the lower end side. The transplanting tool 18 swings with the rotation of the rotating case 17 so that the transplanting claws move in a vertically long closed loop-shaped transplantation locus, and the transplanting claws move from the seedling mounting table 16 by one strain. The seedlings are divided and held, and the seedlings are planted on the soil surface of the paddy field which has been leveled by the leveling floats 20 and 21.

On the other hand, the drive shaft 9 of the planting device of the rotating case 17
8 transmitted from gear 8 via gears 99 and 101
7, each of the fertilizer application driven shafts 53 of the fertilizer application device 39 is
6. The rotation is transmitted in a certain direction via the lever 95 ratchet mechanism 94. For this reason, when the clutch 54 is set to "ON", the feeding roll 46 is rotated, and the fertilizer is fed from the fertilizer tank 41, discharged to the lower funnel 74, flows down the guide tube 43, and flows into the groove forming device. It is discharged to the opening 44.
At this time, the pressurized air from the blower 42 is stored in the air tank 47, and the high-pressure air is blown into the guide pipe 43 below the funnel 74 through the wind pipe 48, thereby forcing the fertilizer to flow down the guide pipe 43. In this way, the fertilizer scattered in the groove opened by the groove generator 44 is guided back into the groove device 44, and then the groove is buried back by the soil covering plate 107 and buried under the soil surface. .

In this manner, the seedling planting operation and the fertilizing operation are performed simultaneously. To adjust the amount of each fertilizer feeding device 45 respectively, the gear 90 is moved to disengage with the gear 51, The gear 51 may be rotated forward or reverse to move the gear 51 left and right with the screw of the cylinder shaft 50, and thereby the feed adjusting roll 46b may be adjusted by moving.
Further, in order to adjust the feed amount of each fertilizer feed device 45 at once, the rotation of the rotating shaft 89 with the lever 88 in the forward and reverse directions will cause the gear 90 to rotate.
, The gear 51 is rotated and the adjustment can be performed in the same manner as described above.

Next, when the work is completed and the fertilizer in the fertilizer tank 41 is discharged, the fertilizer discharge gutter 61 is opened as shown by the imaginary line in FIG. When the member 66 is pulled out, the fertilizer in the tank 41 is received by the fertilizer take-out gutter 61 and discharged as it is to the outside on the rear side. The discharged fertilizer may be appropriately received in a container. Also, when cleaning the feed roll 46 of the fertilizer feeding device 45 and other appropriate portions and draining water after cleaning, the blower 42 is removed and air is blown to facilitate cleaning and draining.

In particular, a sub-transmission case 15b, a fertilizer tank 41 juxtaposed in the lateral direction of the body above the rear, a fertilizer feeding device 45 for feeding fertilizer from the fertilizer tank 41, and a fertilizer application driven by operating the fertilizer feeding device 45 Since the shaft 53 is provided, a plurality of sub-transmission cases 15b are provided at the rear upper portion of the fertilizer tank 41 of the fertilizer application device 39 and a fertilizer feeding device 45 for feeding fertilizer from the fertilizer tank 41, and a fertilizer application driven shaft for operating the fertilizer feeding device 45. 53 can be arranged compactly in the lateral direction of the aircraft. Further, the fertilizer feeding device 45 is located above the planting device 19 mounted on the rear part of the sub-transmission case 15b, so that the fertilizer fed from the fertilizer feeding device 45 is located immediately below the planting position. Appropriately nearby,
Appropriate fertilization work can be performed with less occurrence of clogging of fertilizer.

Of course, a sub-transmission case 15b is provided behind the rear bearing case (R) with a fertilizer application transmission case 100 narrower than the bearing case (R), and a drive system to the planting device 19 is provided.
