The fertilizing device 13 is removably attached to the passenger vehicle body l. On the other hand, the support rod 27 is engaged with the upper end of the seedling stand support rod 30 that supports the upper part of the seedling stand 15 of the transplanting section 12 from below through a support arm 31, and is removably engaged. A stop tube 32 is provided. Then, when removing the support rod 27 from the support tube 28, the air chamber /<-2
Remove the feed lfi TT i 3 from 1, pull out the support rod 27 from the support tube 28, and bend the fertilization pipe 24, while
By locking the support rod 27 to the locking cylinder 32, the fertilizer hopper 18, the feeding section 19, the front and rear passages 20, the air chamber 21, the fertilizing pipe 24, etc. are supported diagonally as shown by the imaginary line in FIG. That's what I do. At this time, the transplant portion 12 may be attached to the elevating link 11 or may be removed.

In a transplanter equipped with a fertilization device configured as described above,
When carrying out work, the passenger vehicle body L is driven to transplant seedlings.
It is introduced into the field (paddy field) where fertilization work is performed. Then, the transplant part 12 is lowered by the lifting link 11 and the float 16 is lowered.
The seedling transplanting operation and the fertilizing operation are performed simultaneously by grounding the passenger car body 1 and driving the passenger vehicle body 1 in this state, and at the same time operating the transplanting section 12 and the fertilizing device 13.

At this time, the passenger traveling vehicle body 1 travels in a four-wheel drive state with the front wheels 3 and rear wheels 4 each driven, so that it can travel even in muddy soil such as rice paddies with almost no pickpockets or knobs.

In the transplanting section 12, the float 16 slides while touching the rice field to level the rice field, and the seedlings are planted on the leveled rice field by placing the seedlings on the leveled rice field while the body 17 rotates in a rotary manner. Seedlings are taken out one by one from the inclined lower end position of a seedling platform 15 that moves back and forth from side to side and planted on the rice field. In addition, since the transplant part 12 can roll left and right at the connection part with the elevating link IT, it can roll independently of the passenger vehicle body 1 when the float 16 is in contact with the ground, and the long planting part can be placed at both left and right ends of the part. When planting seedlings on the side, there is no unevenness in the depth. When the passenger vehicle body l pitches and the transplant portion 12 moves up and down via the elevating link 11,
Along with this vertical movement, the float 1B rubs up and down to switch the hydraulic switching valve, and the hydraulic cylinder 1O is operated to expand and contract to raise and lower the transplanted part 12 via the lifting link 11, thereby keeping the ground pressure of the float 16 almost constant. The depth of the seedlings planted by the body 17 is almost constant.

In the fertilizer application device 13, the powder/granular fertilizer stored in the fertilizer hopper 18 is delivered downward by a predetermined amount by the delivery unit 19 and falls into the front and rear passages 20. 23 - The fertilization is blown backward by the pressure wind from the air chamber 21 and brought to the fertilization nozzle 25 through the fertilization pipe 24, from where it is applied to the fertilization grooves opened in the field by the groove plate 2B. The fertilization position is between the shoots to be planted by the transplanting body 17 and is closer to the seedlings. When the amount of fertilizer in the fertilizer hopper 18 decreases during fertilization work and reaches the position of the fertilizer out sensor 18c, the fertilizer out sensor 18c is activated to notify that the fertilizer is out, and the operator replenishes the fertilizer. This detection of fertilizer shortage is performed in the hopper 18b with a smaller capacity, so the hopper 18a with a larger capacity
However, there is no risk that the fertilizer will run out before this point.

When removing the transplant part 12 from the passenger vehicle body l, it is sufficient to remove it from the connection part with the elevating link 11. In addition, when removing the fertilizer application device 13 from the passenger vehicle body l, first remove the blower pipe 23 from the air chamber 21, then pull out the two pins 29 from the joint between the support tube 28 and the support rod 27, and The support rod 27 is pulled out from 28, and the support rod 27 is locked to the locking tube 32 provided in the transplant section 12 while bending the fertilization pipe 24. By doing so, the fertilizing device 13 is locked to the transplant section 12, as shown by the imaginary line in FIG. At this time, the transplant portion 12 may be attached to the elevating link 11 as shown in FIG. 1, or may be removed from the elevating link 11. When assembling the fertilizer application device 13 to the passenger vehicle body l in this state,
The support rod 27 is removed from the locking tube 32 of the transplant section 12 and inserted into the support tube 28, and fixed by inserting the two bottles 29 into the insertion holes. Then, simply by connecting the blower pipe 23 to the air chamber 21, the assembly work of the fertilization device 13 is completed. Therefore, the work of attaching and detaching the fertilizing device 13 is extremely difficult.
ill tit can be done easily and in a short time.

Next, a second embodiment of the present invention will be described with reference to FIGS. 4 and 5.

With such a configuration, during fertilization work, the feeding section 1
The fertilizer falling into the front and rear passages 20 from the air chamber 21 is blown away backward by the pressure wind from the air chamber 21, so that the fertilizer does not remain in the stage N35 or the orifice 3B.

However, when the transplant part 12 is lifted up by the lifting link 11 when fertilization work is not performed, the fertilization pipe 24 is also lifted up and remains inside the fertilization pipe 24, or the fertilization pipe 24
The fertilizer that had adhered to the inner surface is returned to the front and rear passages 20 side and accumulates in the stepped portion 35 or orifice 36, preventing it from flowing into the air chamber 21 or clogging the front and rear passages 20. .

In the embodiment shown in FIG. 8, the feeding part 19 is directly connected to the air chamber 21, communicated with the front and rear passages 20 through a communication pipe 37 bent in an L shape from the bottom of the air chamber 21, and the air In the chamber 21, the end of the communication pipe 37 is made to protrude above the bottom surface of the air chamber 21 to form a protrusion 38.

In the configuration of this embodiment, after the fertilization work is completed, water is poured into the fertilizer hopper 18 and
When cleaning the feeding part 19, the front and rear passages 20, the fertilizing pipe 24, etc., the protruding part 38 prevents the cleaning water and the fertilizer remaining therein from entering the air chamber 21.

The embodiment shown in FIG. 9 has the front and rear passages 20, air chambers 21, . The blower 22, the air pipe 23, etc. are omitted, and the fertilizing pipe 24 is directly connected to the feeding part 19, and the fertilizing pipes 24 on both sides of the rear wheel 4 are arranged so as not to cross the rear wheel 4 so as to straddle the rear wheel 4. This is what I did.

In this embodiment, the fertilizer dispensed from the dispensing section 19 during the fertilization work flows straight into the fertilization pipe 24 and is fertilized. Lifting link 1 when not fertilizing
When the transplant part 12 is lifted up by the method 1, the fertilizing pipe 24 is also lifted up, but the fertilizing pipe 24 is only curved at the middle part where it hangs down, and the fertilizing pipe 24 is not clogged with fertilizer.

It should be noted that the present invention is not limited to the rice transplanting machine of the above-mentioned embodiment, but can be similarly applied to, for example, a transplanting machine for canola seedlings, a transplanting machine for germinated seeds, and the like.
