However, when mud or the like gets on the float when the transplanter works in the field, the float sinks into the field, but the flat body is generally attached to the float side. However, there is a problem in that it sinks into the field together with the float, and as a result, the leveling body forms a groove M in the field E as shown in FIG. 4, and scratching (ground work) has already been performed. Transplants (seedlings) in existing fields
When transplanting, since the field has already been scraped,
Similar to the above (similar to FIG. 4), there is a drawback that the leveling body, on the contrary, disturbs the leveling of the field (formation of the groove M).

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an embodiment of a riding rice transplanter (Hello rice transplanter) to which the present invention is applied. The Hello rice transplanter is a transplanting device behind a traveling machine body 1 supported by front and rear wheels 2 and 3 as in the conventional case. The planting machine 7 is connected to the traveling machine body 1, a driver's seat 4 is provided, and the planting machine 7 is provided with a seedling stand 6 at the rear. At this time, the planting machine 7 is connected to the traveling machine body 1 via the elevating link 8 so as to be vertically movable and rollable.

The planting machine 7 is provided with a vertical frame 11 vertically provided on the rear side of the seedling placing table 6 and integrally fixed to the vertical frame 11, and below the vertical frame 11 in the left-right direction. It has a horizontal frame 12 that is installed horizontally,
A plurality of planter cases 13 are attached to the lateral frame 12 side. At this time, a planting section 14 for scraping and planting seedlings from the lower end of the seedling placing table 6 is attached to the rear end of each planter case 13.

The planting machine main body 15 is constituted by the planting section 14, the seedling placing stand 6, the planter case 13, both frames 11, 12 and the like. Below the planting machine main body 15, a link mechanism is provided. As shown in FIGS. 1 and 2, a plurality of floats 17 are attached in the left-right direction via 16, and the planting machine main body 15 is supported by the float 17 to configure the planting machine 7 as described above. ing. Further, a roller-shaped scraping rotor 18 having a length substantially corresponding to the width of the planting machine 7 can be rotationally driven in the planting machine body 15 as a ground work machine for performing work on a field at a front side position. Rotor shaft 1
It is pivotally supported by 9 and is arranged so that it can be grounded.

In other words, the planting machine 7 is grounded and supported so that the float 17 is grounded in the field so that it can slide on the field.
By rotating the rotor shaft 19 by rotating the rotor shaft 19 to the ground and activating the planting part 14, only the surface layer portion of the soil cultivated by the rotor for scraping 18 rotated by the rotor shaft 19 is scraped and planted. The attachment section 14 has a structure in which the mat-like seedlings in the seedling placing table 6 are scraped off one by one and the surface layer is planted in a field where the surface has been scraped.

At this time, a plate-shaped lever guide 21 is fixedly provided on the vertical frame 11 side, and an operating lever 22 is inserted through the lever guide 21 so as to be swingable. On the lever 22 side, the other end of a rod 23 that rotatably supports the rotor shaft 19 on one end side is connected so as to be movable up and down as the operating lever 22 swings. Is supported by the planting machine body 15 side so as to be vertically movable.

The swinging position of the operating lever 22 is positioned by the positioning portion of the operating lever 22 formed on the lever guide 21, so that the height of the substitute scraping rotor 18 with respect to the planting machine 7 (planting machine body 15). As shown in FIG. 3, the rod 23 is slidably inserted into a collar 26 fixed to the lateral frame 12 side via a bracket 24, and is positioned in the front-rear direction. It is configured to move up and down in a closed state.

That is, the sub-scraping rotor 18 has a working posture in which the sub-scraping of the field can be performed by rotating while being grounded in the field, and the rotor 18 is separated from the field so that the sub-scraping of the field cannot be performed. It is supported so that it can be switched to the storage posture that is stored on the machine 7) side. It has a structure that can perform any of the normal planting work in which planting is performed without scratching.

On the one-side scraping rotor 18 side, a side cover 20 for covering the side of the sub-scraping rotor 18 and an upper cover 27 for covering the upper side are provided as in the conventional case. The upper cover 27 uniformly covers the field. A supporting device 29 for supporting the plate-shaped leveler 28 which is a flat and level body is provided, and is supported by the supporting device 29 and outside the side floats 17s arranged on both outer sides of the planting width. The levelers 28 are arranged between the side floats 17s and the central float 17c arranged in front of the side floats 17s.

At this time, the leveler 28 moves the floats 17
Is curved in a shape substantially along the warp surface 17a of the tip end portion of the float 17, and is disposed in front of each float 17 so that a part thereof overlaps with a part of the float 17 in a plan view. A predetermined gap 31 is formed between the upper surface of the and the bottom surface of the float 17 (the sled surface 17a).

Next, the mounting structure of the leveler 28 will be described. The support device 29 includes a support rod 32 protruding rearward from the upper cover 27 side, a connecting shaft 34 slidably inserted in a vertical direction into a boss 33 provided at the tip of the support rod 32, and the connecting shaft 32. 34 and a boss 33, the spring 36 is provided to urge the connecting shaft 34 downward, and the leveler 28 is fixed to the connecting shaft 34.

The downward movement of the connecting shaft 34 is determined by the contact between the head 34a (projecting from the upper end of the boss 33) of the connecting shaft 34 and the upper end of the boss 33, and the bottom surface of the leveler 28 is float 17. It is regulated so that it is almost the same height as the bottom surface of. When the scraping rotor 18 is in the working posture, the leveler 28 is in contact with the field and the scraping rotor 1
When the storage posture is 8, the leveler 28 is set to be separated from the field.

In the case of performing the above-mentioned scraping planting work by the structure shown above, in the field not flattened by the float 17 such as the outside of the side float 17s and between the side float 17s and the central float 17c. Although the part is leveled by the leveler 28, since the leveler 28 is attached to the work machine body 15 side (the scraping rotor 18), it is elastically grounded independently to the float 17 in the field to perform the leveling work. I do.

Therefore, even when the float 17 sinks in the field due to work in a relatively soft field or mud on the float 17, the leveler 28 is prevented from sinking in the field and the leveler 28 is Since a predetermined leveling force is maintained with respect to the field, inconveniences such as forming grooves in the field are prevented, and the field is made flat (without grooves etc.) as shown in FIG. The ground can be satisfactorily laid, the scraping and planting work can be satisfactorily performed, and the stable planting work can be performed.

Further, since each float 17 is pressed against the field scene as the traveling machine body 1 travels, the mud on the field scene is pushed by the float 17 and is pushed. The pushed mud is floated. As shown in FIG. 2, it flows behind the leveler 28 through the gap 31 between the leveler 28 and the leveler 28. Therefore, between the floats 17, the mud water flowing from both the left and right sides joins and weakens the momentum, Is guided and discharged to the rear of the outer side float 17s, and is guided to the outside of the outer float 17s and discharged.

As a result, the discharge of the muddy water swept away by the float 17 to the planted seedling side is reduced, and the planted seedlings planted at the planting point indicated by X in FIG. Is prevented.
That is, a guide path 37 is formed to guide the water flow (muddy water) pushed by the float 17 or the like by the gap 31 to the rear of the leveler 28.

On the other hand, when performing the above-mentioned normal planting work (planting seedlings in the existing scraping field), the scraping rotor 18 is used.
In this case, the leveler 28 is moved away from the field as described above, so that the leveler 28 does not come into contact with the field during the normal planting work and the leveler 28 forms a groove or the like in the field. Inconveniences are prevented, and stable and good planting work (good ground leveling) similar to that of a normal planting machine (rice transplanter) can be performed.

[0023]

According to the structure of the present invention configured as described above, in the same manner as in the past, in the field, the side of the float and the portion which is not leveled by the float such as between the floats are leveled by the leveling body, In particular, since the leveling body is attached to the ground work machine side, when carrying out transplanting work and grounding work (such as scraping work) at the same time, the leveling body is grounded independently to the float and grounded in the field. There is an effect that work is performed, a predetermined leveling force is maintained regardless of the sinking of the float, and the inconvenience of forming a groove in the field is prevented.

If the ground work machine can be moved up and down,
When performing transplanting work in a field where ground work such as scraping has already been completed, the flat body is retracted (raised) upward together with the ground work machine and separated from the field scene. There is also an advantage that adverse effects (such as formation of grooves) on the surface are prevented.

Further, by forming a guide path between the float and the leveling body, which guides the water flow pushed by the float to the rear of the leveling body, an implant (such as a plant) such as muddy water swept away by the float is formed. The discharge to the seedling side) is reduced, and the transplanted matter is prevented from being fallen down by the muddy water or the like.
