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

The transplanting section I2 has a main body frame 14 provided with a seedling mounting table 15 located on the upper side, on which seedlings for transplantation are placed and reciprocated from side to side with a predetermined stroke, and a seedling table 15 on the lower side.
B is provided at the rear, and the seedlings are taken out one by one from a seedling outlet (not shown) provided at the sloping lower end of the seedling platform 15 and planted in the field while rotating in the direction of movement of the machine. A body 17 is provided for planting. Above float 1
Although not shown, reference numeral 6 is supported by a link mechanism to be movable up and down relative to the main body frame 14, and a hydraulic switching valve that is switched by the vertical movement of flow 1B is provided near the link mechanism. The above-mentioned hydraulic cylinder IO is telescopically operated to lift the lift link 1.
The transplanting part 12 is raised and lowered through the body 1, and the ground pressure of the float 16 is kept almost constant, and the seedlings are planted using the body 17 so that the depth of the seedlings is almost constant. The reference numeral 15a is a seedling guide provided at the upper end of the seedling stand 15.

The above-mentioned fertilizer application device 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/granular fertilizer is provided in the upper part, and a passenger A feeding section 19 is provided which is driven by receiving power from the traveling vehicle body l and feeds out a predetermined amount of fertilizer in the hopper 18 downward.A front and rear passage 20 is provided for the fertilizer fed out from this feeding section 19 to fall, An air chamber 21 extending in the left-right direction and serving as a frame is disposed in communication with the front side of the passage 20, and a blower 22 is communicated with the front part of the air chamber 21 via a bellows part 30 and a blow pipe 23.

A fertilization pipe 24 made of a 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 2B is attached to the front side of the. By supporting the air chamber 21 via a rear wheel support frame 27 and a support rod 9, which will be described later, the fertilizer application device I
It supports each part of 3.

The rear wheel support frame 27 that supports the pair of left and right rear wheels 4, 4 is a rolling frame provided at an intermediate portion in the longitudinal direction. To
28 is pivotally connected to the vehicle body frame 2, and the rear wheels 4.4 can roll left and right. Further, the lower part of the support rod 29 is fixed to the rear wheel support frame 27, and the tip of the support rod 29 is fixed to the air chamber 21, and when the rear wheel 40-link shaft 28 is rolled from side to side, the fertilizer application device f1
3 is also rolling together.

The front frame 2a of the vehicle body frame 2 is inclined so that its tip side is higher, and a bumper 3I is provided at the tip of the front frame 2a so as to be slidable back and forth as shown in FIG. There is.

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 1 runs in a four-wheel drive state with the front wheels 8 and rear wheels 4 each driven, so it can run with almost no slipping even on muddy soil such as rice paddies. Because the wheels roll independently, even if there are some irregularities or undulations on the ground (the plowing platform) that the front wheels 3 and rear wheels 4 touch, the rolling of the rear wheels 4 will absorb this and cause the entire passenger vehicle body to roll significantly. Also, pitching is significantly reduced compared to a model where the rear wheels do not roll. Simultaneously with this rolling of the rear wheel 4, the fertilizing device 13 also rolls. As a result, the horizontal tilting and vertical movement from the passenger vehicle body l side to the transplantation part l2 side are reduced, and the working performance of the transplantation part 12 is not adversely affected.

Further, since the fertilizing device 13 rolls together with the rear wheel number, there is no problem even if the gap between the rear wheels 4 and the fertilizing device 13 is reduced, and the machine body can be made more compact. Furthermore, even if the vehicle body sinks to some extent in deep plowed paddy fields, the front frame 2a faces upward, which prevents the bumper 31 from pushing mud. Even when carrying luggage, the luggage will not get wet due to muddy water.

In the transplanting section 12, the float 16 slides while touching the stamp surface to level the rice field, and the body 17 rotates in a rotary manner to plant seedlings on the leveled rice field, placing the seedlings on the rice and moving them from side to side. Seedlings are taken out one by one from the lower end of the slope of the seedling platform 15 that moves back and forth 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 U, it can roll independently of the passenger vehicle body l when the float 1B 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 part 12 moves up and down via the elevating link 11, the float 1B moves up and down with this up-and-down movement, switches the hydraulic switching pulp, and causes the hydraulic cylinder lO to telescopically operate. to raise and lower the transplant unit 12 via the lifting link 11,
Seedlings are planted by the body 17 while keeping the ground pressure of the float 1B substantially constant, and the planting depth of the seedlings is substantially 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 section 19 and falls into the front and rear passages 20. Pipe 23 - It is blown backward by the pressure wind from the air chamber 21 and is brought to the fertilizing nozzle 25 through the fertilizing pipe 24, from where it is fed to the open groove plate 2B.
Fertilizer is applied to the fertilization ditches cut into the rice fields. The fertilization position is between the shoots to be planted by the transplanting body 17 and is closer to the seedlings.

Next, as shown in FIG. 3, a plurality of horizontal frames 32 (three in the drawing) are installed on the body frame 2 of the passenger vehicle body l, and the hydraulic cylinder 10 is mounted on one of the horizontal frames 32.
The engine 5 is supported on the horizontal frame 32 via an engine support member 33. Therefore, a space is formed below the engine 5, and tools and the like can be stored in this space.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but can be similarly applied to, for example, a transplanter for Satsatsu rape seedlings, a transplanter for germinated seeds, and the like.

〔Effect of the invention〕

As explained above, according to the transplanter equipped with the fertilization device/device of the present invention, the following effects can be achieved.

(B) The left and right rear wheels of the passenger vehicle body can be rolled by the rear wheel 4 support frame and the rolling shaft, and the fertilizer application device is supported by the rear wheel support frame, so when the rear wheels roll, the fertilizer application device also rolls. However, even if there are some irregularities or undulations on the ground where the front and rear wheels come into contact, the rolling of the rear wheels absorbs this and prevents the entire passenger vehicle from rolling significantly.
Pitching can also be significantly reduced compared to a model where the rear wheels do not roll. As a result, the horizontal tilting and vertical movement of the transplanted part from the passenger vehicle body side are reduced, and the working performance of the transplanted part is not adversely affected.

Also, since the fertilizer applicator rolls with the rear wheels,
There is no problem even if the gap between the rear wheels and the fertilizer application device is made small, and the machine body can be configured compactly.

0 The front frame of the passenger car body was tilted so that the front end was higher, and a bumper was slidably provided at the tip of the frame, so the car body sank slightly when the passenger car drove through deep plowed rice fields. The bumper prevents mud from pushing even when the vehicle is in use.

Further, even when the bumper is slid forward and cargo is loaded onto the extended portion of the bumper, the cargo will not get wet with muddy water.
