A steering handle 8 is provided on the front side of the driver's seat 7, and a support frame 9 installed upright at the rear end of the vehicle body frame 2 has the base of an elevating link 11 whose rear end side moves up and down by rotating with the expansion and contraction of a hydraulic cylinder IO. The end portion is pivotally supported, and the rear end portion of this elevating link 11 is planted with multiple rows (
In this embodiment, six (6) graft portions 12 are connected so as to be rollable from side to side.

A fertilization device 13 is disposed between the transplant section 12 and the driver's seat 7.

The transplanting section 12 has a main body frame I4 with a seedling mounting table 15 located on the upper side on which seedlings for transplantation are placed and reciprocating from side to side with a predetermined stroke, which is installed diagonally together with a seedling mounting table support rod 27. A float 16 is provided on the lower side, and seedlings are taken out one by one from a seedling outlet (not shown) provided at the sloping lower end of the seedling platform 15 while rotating in the direction of movement of the machine at the rear. Therefore, it is necessary to plant seedlings in the field.
has been established. Although not shown, the float 16 is supported by a link mechanism to be movable up and down relative to the main body frame 14, and a hydraulic pressure switching valve that is switched by the vertical movement of the float 16 is provided near the link mechanism. The above hydraulic cylinder lO by the valve
is operated to expand and contract to raise and lower the transplant part 12 via the lifting link 11, keeping the ground pressure of the float 16 almost constant,
The seedlings are planted using the body 17 so that the depth of the seedlings is approximately constant. The reference numeral 15a is a seedling guide provided at the upper end of the seedling stand 15.

The above fertilizer bag! 13 has the same number of fertilization rows (6 rows) as the number of seedling planting rows in the transplanting section 12. A fertilizer hopper 18 for storing powder and granular fertilizer is provided in the upper part, and a passenger vehicle body l is provided in the lower part. A feeding section 19 is provided which is driven by receiving power from the hopper and feeds out the fertilizer in the hopper 18 downward by a predetermined amount,
A front and rear passageway 20 is provided in which the fertilizer fed out from the feeding section 19 falls, and an air chamber 21 that extends in the left-right direction in front of the front and rear passageway 2o and also serves as a frame.
are arranged in communication with each other, and a blow pipe 23 from a blower 22 is communicated with the front part of this air chamber 21. A fertilization pipe 24 made of a flexible synthetic resin hose is communicated with the rear end of the front and rear passage 20 and extends close to the field, and a fertilization nozzle 25 is connected to the lower end of this fertilization pipe 24. , an open groove plate 26 is attached to the front side of the fertilization nozzle 25.

Further, as shown in FIG. 2, the fertilization pipe 24 has a support ring 28 inserted thereinto at its upper position, and two support rings 2g.
, 2g are connected by a connecting rod 28a, and the middle portion thereof is suspended from the seedling stand support rod 27 via a spring 29. Therefore, the fertilizing pipe 13 is the transplanting part! 2, it is supported by a spring 29 so as to be lifted upward. Furthermore, as shown in FIG.
The outer circumferential surface of the support ring 2 is formed into a wavy shape 24a, and a wavy shape 28a that fits into the wavy shape 24a forms the support ring 2.
It is formed on the inner peripheral surface of 8. Therefore, the fertilizing pipe 24 supported by the support ring 28 does not move easily.

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 at the same time by grounding the passenger car body 1 and driving the passenger vehicle body 1 in this state, and simultaneously operating the transplanting section 12 and the fertilizing device 13.

At this time, the passenger vehicle body runs in a four-wheel drive state with the front wheels 3 and rear wheels 4 each driven, so that it can run with almost no slipping even on muddy soil such as rice paddies.

In the transplanting section 12, the float 16 slides while touching the rice field to level the circular surface, 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 lower end of the slope of the seedling platform i5, which moves back and forth from side to side, and planted on the rice field. In addition, since the transplanted part I2 can roll left and right at the connection part with the elevating link 11, it rolls independently of the passenger vehicle body 1 when it is in contact with the ground at flow hlB, and the transplanted part I2, which is long in the left and right, 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 II,
Along with this vertical movement, the float 16 is driven up and down to switch the surface pressure switching valve, and the hydraulic cylinder IO is telescopically operated to raise and lower the transplanted part 12 via the lifting link 11, thereby keeping the ground pressure of the float i6 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 fed out downward in a predetermined amount by the feeding unit 19 and falls into the front and rear passages 20, and in the process of falling, the powder/granular fertilizer is released by the blower 22. The fertilizer is blown backward by the pressure wind from the pipe 23-air chamber 21, passes through the fertilization pipe 24, and is brought to the fertilization nozzle 25, from where it is applied to the fertilization groove opened in the rice field by the groove plate 26. The fertilization position is between the shoots to be planted by the body 17 of the transplanting part 12 and is closer to the bacterial strain.

When the transplant part 12 is lifted up by the lifting link 11 when fertilization work is not being performed, the fertilization pipe 24 is also lifted up together with the transplant part 12, but at this time, the fertilization pipe 24 is moved by the spring 29 as shown in FIG. The fertilizing pipe 24 can be lifted up without difficulty, and the fertilizing pipe 24 will not interfere with or come into contact with other members, and will not be unnecessarily bent or sagged. Also,
Since the wavy shape 24a of the fertilizing pipe 24 fits into the wavy shape 28a of the support ring 28, the fertilizing pipe 24 does not easily move from the support ring 28, and wear and tear of the fertilizing pipe 24 are prevented. Ru. .

Next, in another embodiment of the connection structure between the front and rear passages 20 and the fertilizing pipes 24 shown in FIGS. 4 and 5, each fertilizing pipe 2
4.24... are connected with the connecting tool 30, and the engagement hook 31 provided on the front and rear passage 20 side is engaged with the connecting tool 30, 1111
This allows the plurality of front and rear passages 20 and the fertilization pipe 24 to be attached and detached at once by removing the tube.

In this embodiment, the operation of attaching and detaching the front and rear passages 20 and the fertilizing pipe 24 can be performed simply, easily, and in a short time.

The embodiment shown in FIGS. 6 and 7 has marker hooks 3 on both left and right sides of the support frame 33 of the seedling stand 15.
4, and attach marker 3 to this marker hook 84.34.
2.32, and attach the two fertilizer pipes 24 to the support frame 33 and marker hook 34 with the support ring 2.
8 and suspended via a spring 35.

In this embodiment, each fertilization pipe 24 is supported within the left and right width range of the support frame 33 and the marker hook 34, so when the fertilizer application work is not performed, the transplant section 12 can be moved by the lifting link 11. When lifted, the fertilizing pipe 24 touches both left and right ends of the marker hooks 34, 34, i.e.
Both left and right ends of the seedling platform 15 do not protrude outward from the width, so that they do not get in the way when the machine is moved.

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.

〔Effect of the invention〕

As explained above, according to the transplanter equipped with the fertilization device of the present invention, when the transplant section is lifted up when no fertilization work is being performed, the fertilization pipe is also lifted up together with the transplant section; The fertilizing pipe is elastically supported by a spring and can be lifted up without difficulty, so that the fertilizing pipe does not interfere with or come into contact with other members, and damage is prevented.

In addition, the fertilizing pipe does not bend or sag unnecessarily, improving workability and durability.
