DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a side view of a planting machine 1 connected to a rear of a riding rice transplanter, which is a paddy working machine, and the planting machine 1 is a rear side of a traveling body of the riding rice transplanter. , Via a lifting link (both not shown), and is located behind the rear wheels 2 of the traveling body.

At this time, the planting work machine 1 has a structure in which a leveling float 3 is provided at a lower portion, similarly to the structure attached to a conventional riding rice transplanter. The seedling placed on the seedling rest 7 is planted by a planting part (rotary planting part) 6 for planting provided in a planting case (plant case) 4 and is scraped and planted. It is structured to perform work.

As shown in FIGS. 2 and 3, the planting work machine 1 has three planter cases 4 and the leveling floats 3 are supported on the respective planter case 4 sides. Also, three leveling floats 3 are provided corresponding to the planter case 4. The leveling floats 3a and 3b on both the left and right sides are arranged right behind the rear wheels 2 of the traveling machine body, and are provided so that the rear wheels 2 pass over the wheel traces formed on the field scene.

On the other hand, as shown in FIG. 4, the leveling float 3 has a wide upper portion 8 formed by warping upward on the front side, and has a width continuous from the rear end side of the upper portion 8 on the rear side. It forms a narrow (compared to the upper portion 8) horizontal portion 9 and is connected to the planter case 4 side via a link mechanism 11. On the bottom surface 12, a concave groove 13 for flowing mud is formed in the front-rear direction. On the right and left sides of the groove 13 on the bottom surface of the upper portion 8, a pair of left and right guide members 14 protruding downward are provided extending in the front-rear direction.

As is conventionally known, the front side of the groove 13 widens in a fan-like manner at the front side, the rear side is narrower than the width of the rear wheel 2 and extends rearward, and the terminal end thereof becomes shallow at the rear end side of the leveling float 3. I have. The guide member 14 has a substantially arc shape in a side view and a plan view (bottom view), and is substantially along the front side of the groove 13 so that the left and right protrusions 14 are closed rearward with the groove 13 interposed therebetween. It has an inverted C-shape, and has a mounting portion 15 on the outer side of the ground floats 3a, 3b.

As a result, as shown in FIGS. 4 and 5, the mounting portion 15 of each guide member 14 is fixed to a left-right plate-shaped base 18 fixed to the upper surface of the front end of the leveling floats 3a and 3b. It is attached to the ground floats 3a, 3b, extends rearward, and protrudes toward the bottom surface of the leveling float 3. Note that a part of the mounting portion 15 is located on the bottom surface side of the leveling float 3, and forms a grounding portion 22 that is grounded to a field when the leveling float 3 is grounded.

At this time, the mounting portion 15 is fixed to a positioning hole 18a provided in the base 18 via a fixing tool such as a bolt 17, and the base 18 (the leveling floats 3a, 3a).
b), a plurality of the positioning holes 18a are formed in the left-right direction.
By changing the positioning hole 18a for attaching the five parts,
The structure is such that the distance between the two guide members 14 can be freely adjusted.

Thus, when the traveling machine travels in the field and the planting work machine performs the planting operation, the wheels (rear wheels 2) of the traveling machine are partially buried in the field (while sinking).
Rotate and run the traveling aircraft. Therefore, the rear wheel 2
Pushes the mud of the field to the outside of the wheel, and a wheel mark 16 which is a concave groove is formed in the field.

However, as the leveling floats 3a, 3b at the left and right ends pass over the wheel mark 16, the guide member 14 guides and moves the mudflow in the field scene to the inside.
The soil leveling float 3 leveles (levels) the field while burying the mud or the like raised on both sides of the wheel in the wheel mark 16.
As a result, a relatively large amount of mud filling the wheel traces 16 is collected, and leveling work using the leveling float 3 is efficiently performed.
The levelness of the field scene is improved.

As a result, the wheel marks 16 are efficiently filled, the sinking caused by the wheel marks 16 at the rear of the leveling floats 3a, 3b is prevented, and the rolling support of the planting work machine 1 is further strengthened. The planting performance of the attachment working machine 1 is improved. When the field is leveled by the leveling float 3, the mudflow (muddy water and mud) on the field scene is guided rearward through the groove 13 on the lower surface of the leveling float. The mud flow is smoothly guided to the side.

On the other hand, as shown in FIGS. 6 and 7, the planting machine 1 in which the leveling float 3 passes on the left and right sides of the wheel mark 16 by arranging four planter cases 4 and four leveling floats 3 respectively. In the case of, the guide members 1 are respectively provided at opposing portions of the leveling floats 3c and 3d located on both sides of the wheel mark 16.
4 may be provided.

In this case, as shown in FIGS. 6 to 8, the guide member 14 has a structure in which a mounting portion 15 fixed to the leveling floats 3c and 3d is integrally formed.
By fixing the 5 to the leveling floats 3c and 3d, the guide member 14 is arranged so as to protrude toward the wheel mark 16 side of the opposing floats 3c and 3d. At this time, the mounting portion 15 is provided with a mounting hole composed of a long hole 20 in the left-right direction, and the mounting portion 15 is mounted on the leveling floats 3c, 3d via the mounting hole 20 by a fixing tool composed of bolts 21. I have.

By adjusting the position of the fixture with respect to the mounting hole, the right and left positions of the guide member 14 with respect to the leveling floats 3c and 3d can be adjusted. That is, the guide members 14 are provided on both the leveling floats 3c and 3d. The two guide members 14 form a pair of left and right, and the distance between the pair of left and right guide members 14 can be adjusted freely. In addition, the grounding part 2 which is located on the bottom surface side of the leveling float 3 between the guide member 14 and the mounting part 15 and grounds to the field when the leveling float 3 is grounded
Two are playing.

As a result, the guide member 14 draws mud on both the left and right sides of the wheel mark 16 and fills the wheel mark 16 in the same manner as in the above embodiment, so that the leveling floats 3c and 3d are more effective in the case where the wheel does not pass over the wheel mark 16. The leveling of the field is performed, and the leveling efficiency is particularly high as compared with the case where a leveling plate for leveling the wheel traces 16 is provided.

In the case where the leveling float 3 does not pass over the wheel mark 16 as described above, a part of the planting position X is located on the side of the wheel mark 16.
As a result, leveling of the raised soil or the like on the side of the wheel mark 16 is performed, so that the leveling of the planting position X is relatively high, and a more stable planting operation can be performed.

On the other hand, as described above, the leveling floats 3a, 3
Since the guide members 14 are attached to b, 3c, and 3d, by adjusting the distance between the two guide members 14, the amount of contact of the guide members 14 (ground contact portion 22) to the field can be changed. As a result, in a relatively hard field, even if the ground contact area is relatively small, the float performance is not impaired, so that the spacing between the two guide members 14 can be increased to enhance the leveling effect. In the above, the float effect can be enhanced by reducing the distance between the two guide members 14 and increasing the contact area of the guide members 14 with the field, that is, the guide member 14 can cope with the hardness and softness of the field on the leveling float 3 side. It is possible to support.

[0023]

According to the structure of the present invention constructed as described above, a groove-shaped wheel mark is formed by a wheel in a field scene, but the road is raised on both sides of the wheel mark by a guide member of a leveling float. Since the soil and the like are buried in the wheel traces, the levelness of the field scene is improved. In particular, since the distance between the pair of guide members can be freely adjusted, the uniformity is adjusted according to the wheel width. Flat performance can be adjusted.

At this time, when the leveling float passes over the wheel traces, both guide members are attached to one leveling float, and the guide members move soil or the like raised on both sides of the wheel traces into the groove to cause the soil to fall in the wheel traces. In order to fill the land, it is possible to more effectively level the field, and when the leveling float is located on both sides of the wheel mark, the guide member provided on the leveling float located on both sides of the wheel mark In order to guide and fill the soil raised on both sides of the wheel trace to the wheel trace,
A leveling plate is provided on the wheel traces as in the related art, and the leveling of the field can be more effectively performed as compared with the conventional technology in which the leveling wheels are leveled.

On the other hand, since the guide member is attached to the leveling float as described above, by adjusting the distance between the two guide members, the amount of contact of the guide member with the field can be changed. Thereby, it is possible to cope with the hardness of the field, and in a relatively hard field, even if the contact area is relatively small, the float performance is not impaired. On the other hand, in a relatively soft field, the distance between the two guide members is reduced, and by increasing the contact area of the guide member to the field, the float effect can be enhanced.
