2. Description of the Related Art Generally, in a transplanting machine such as a riding rice transplanter in which a planting portion is supported by a center float and a side float that slide on a rice field, seedlings are provided on side floats provided on both outer sides of the body. It is known that a planting recess is provided to form a side float into a portal shape in plan view.

[0003]

In the conventional gate-shaped float, a seedling planting recess opening rearward is provided at the center in the width direction, and both left and right legs have the same width. For this reason, none of the legs are very wide, so the legs located inside the fuselage alone cannot completely erase the traces of the wheels in front of them. There is a problem that it is more difficult to level the wheel traces when both lug wheels overhang are attached,
A wide part is provided on one leg to completely eliminate wheel marks
And the position of the seedling planting recess is the center position of the gate-shaped float
Muddy water flowing from the rear ends of both legs
Merge at a position off the recess. Because of this, seedling planting
Seedlings planted in the part are off the seedling recess.
There was a problem that the muddy water was pushed by one side and disturbed the seedling posture. The present invention was conceived to solve the above-mentioned problems, and it is intended to completely level the traces of wheels mounted in front while forming a side float in a gate shape. The present invention provides a float of a transplanting machine that can perform planting work smoothly without disturbing the seedling posture even if muddy water flowing along the float flows into the seedling planting recess from the rear ends of both legs. It is intended for.

[0004]

In order to solve the above-mentioned problems, the technical means taken by the present invention is a seedling planting recess which is disposed on both outer sides of the fuselage and has an opening only at the rear in the middle in the width direction. In the gate-shaped float provided with, the both legs of the gate-shaped float are formed on a narrow leg located on the outside of the fuselage and a wide leg located on the inside of the fuselage . The gate

Reference numeral 12 denotes a hydraulic cylinder that moves the link mechanism 11 up and down, and reference numeral 13 denotes a steering handle.

Reference numeral 14 denotes a power transmission case of the planting section 8. The power transmission case 14 includes a planting case 15, a drive case 16, and the like, and performs a planting operation at a rear end of the planting case 15. A seedling mounting rod 17 is provided. Above the power transmission case 14, a seedling mounting table 18 is supported so as to be able to reciprocate left and right, and below the power transmission case 14,
A float 19 that slides on a rice field is vertically swingably mounted via a swing link 20. The rotating shaft 21 provided on the drive case 16 is supported by the rear end of the link mechanism 11, so that the entire planting portion 8 can freely roll.

As shown in FIG. 1, the float 19 has a center float 22 disposed at the center of the fuselage, and side floats 23 disposed on both outer sides of the fuselage. The center float 22 supports the planting section 8 and
The hydraulic cylinder 1 senses the elevation of the planting section 8 with respect to the rice field.
2 is operated to control the elevating position. 2
Reference numeral 4 denotes a concave portion formed on both side surfaces on the rear end side of the center float 22.

The side-float 23 has a front-back direction seedling planting recess 25 which is open only at the rear at an intermediate portion in the width direction.
Is formed as a gate-shaped float. Then, the two legs of the gate-shaped float are connected to the narrow width legs 2 located outside the fuselage.
6 and forming the the width Hiroashi portion 27 located on the inboard
Thus , the seedling planting position by the seedling planting recess 25 is formed at a position deviated from the center line of the side float 23 to the outside of the machine body. On the open side of the seedling planting recess 25, a thin portion 28 is formed on the wide leg portion 27, and the thin portion 28 is formed with a recess 29 in the front-rear direction that opens to the rear and the seedling planting recess 25 side. I have. And outside the seedling placement position
The width narrow leg 26 has a length extending from the seedling placement position by the seedling mounting rod 17 to the rear end thereof is longer than the length extending to the rear end of the wide leg 27 and protrudes rearward. By doing

They are joined . Reference numerals 30 and 31 denote recessed portions provided at the outer ends of the rear portions of the narrow width portion 26 and the wide width portion 27, respectively, and open to the rear and side.

The center float 22 is disposed in front of the side float 23. An imaginary line connecting the rear end of the center float 22 and the rear ends of the wide leg 26 and the narrow leg 27 is directed backward. It is spread out. The side float 23 is disposed so as to fit within the outermost trajectory of the apron guard 32 and the apron 33 disposed at a position visible from the driver's seat 7, and is disposed in front of the side float 23. The rear wheel 3 is located.

In the above construction, when the transplanting operation is performed, the float 19 slides on the rice field with the running of the body, and the seedling planting rod 17 which operates to plant the seedling is in contact with the seedling planting recess 25, the center float 22, and the side. The seedlings P are planted between the floats 23. At this time, since the wide leg portion 27 of the side float 23 formed in the gate-shaped float is located inside the fuselage, even if both lugs are mounted on the fuselage, the wheel marks are completely erased and the field scene is erased. Can be equalized. Then, muddy water flows from both sides of the side float 23 toward the seedling planting concave portion 25, but is outside the planting position.

The seedling P at the planting position planted at 25 is the rear end of the narrow width leg 26.
And the muddy water flowing from the rear end of the wide leg 27
The seedling posture will not be disturbed. Also, since the rear ends of the center float 22 and the side floats 23 are arranged so as to extend rearward, the center float 22
The muddy water flowing backward through the opposed gap between the side float 23 and the side float 23 also naturally becomes a divergent flow. Therefore, the muddy water flowing out to the adjacent shoots on the side of the machine body can be reduced as much as possible, and the adverse effect on the already planted seedlings P 2 can be reduced. On the other hand, at the time of the aircraft revolving, if the driver sitting in the driver's seat 7 turns while visually observing the apron guard 32, even if the side float 23 is not visible, the side float 23 may inadvertently touch the ridge or the like. It is possible to reliably prevent the risk of damage due to hit.
