The working machine 5 is moved up and down to adjust the cutting depth.
[0011]
In addition, a plurality of rotor-shaped scrapers 5a to 5d as a scraping work machine 5 to be described later are arranged on the rotating shaft 50 at intervals, and a driving device 51 that rotationally drives the rotating shaft 50 is small. A hydraulic motor 51 that generates a large output is used.
This hydraulic motor 51 is designed to be compactly mounted and driven in a state of being accommodated within the working width formed by the above-described cutting work machine 5, and immediately before the seedlings are planted by the planting claws 62 of the planting device 6. The soil is scraped and leveled so that the planting work can be performed satisfactorily, and the ruins 1e of the rear wheel 1b can be satisfactorily erased by the configuration described later.
[0012]
Moreover, the planting apparatus 6 arrange | positions the center of the said float 71 for one row | line | column, and the planting nail | claw 62 relevant to this in the back on the extension line of the axial center P of the said rolling support shaft 31, as shown in FIG. Yes. A rotating shaft 63a that is pivotally supported in the transmission case 63 is separated from the rolling support shaft 31 to the right by a predetermined distance H, and is provided in the input portion case by a drive shaft 8 that is driven from the traveling machine body 1 side. The bevel gears 8a and 8b are driven to rotate, and the seedling stage 61 is reciprocated in the left-right direction and the planting claws 62 are planted.
[0013]
Next, the detailed structure of the machining apparatus 5 will be described with reference to FIGS.
As shown in FIG. 5, the rotating shaft 50 shown in FIG. 3 is parallel to the outer periphery of the left and right frame plates 53 having polygonal shaft stop holes 52 at predetermined intervals. A hollow cage-shaped rotor-like scraping body 5a to 5d that is arranged and connected to scrape the soil is formed so that the ground can be leveled into a flat surface.
[0014]
And the horizontal axis | shafts of this cage-shaped shaving body 5a-5d are each made into different length, and it can be scratched on the rotating shaft 50 separately at intervals so that the predetermined range ahead of each planting claw 62 can be scratched. The substitute working unit 5 is configured by being axially attached.
That is, as shown in FIGS. 3 and 6, the longest scrapers 5a, 5a are arranged on both outer sides, and the next length is placed inside the scrapers 5a, 5a during the mounting interval of the support arm 66. The scrapers 5b and 5c are arranged. The shortest scraper 5d is placed on the right side of the drive device 51, and the center line of the scraper 5d is provided so as to coincide with the center line C of the center float 71.
[0015]
The left and right rear wheels are mounted between the pair of scrapers 5a and 5b and the pair of scrapers 5a and 5c behind the left and right rear wheels 1b using the mounting interval of the support arms 66 and 66. An interval [L] is provided to backfill and erase the traces 1e, 1e formed on the ground by 1b, 1b. As shown in FIG. 5, the adjacent muddy bodies 5a and 5c and mushrooms and muddy water flows (hereinafter referred to as muddy soil) are moved to the ruins 1e and 1e as shown in FIG. Soil body 57 is provided for backfilling.
[0016]
This cage 57 moves mud or the like toward the rut 1e as it rotates, between the adjacent scrapers 55, 55 in the cage-shaped scraper, slightly inside the tip, with the rotation. As shown in FIG. 6, a pair of scrapers 5a, 5b and a scraper which are paired to rotate in the direction of the arrow as shown in FIG. 6 are provided. 5a, 5c can satisfactorily cut the surface of the paddy field, and the soil mud etc. on the surface layer can be brought to the distance L side by the action of the sloped body 57 to fill the traces 1e, 1e. It can be done. It should be noted that the soil fillers 57 provided on the scrapers 5a and 5b and 5c and 5a are inclined with each other so that the scrapes 5a to 5d rotating in the same direction scrape the soil toward the ruins 1e and 1e. The direction is reversed.
[0017]
Next, as a result of leveling the uneven soil surface of the reclaimed traces 1e, 1e by the floats 70, 70 arranged at the rear, the trace 1e is applied to the field scene where seedlings are planted by the planting device 6. It can be finished in a flat surface without leaving large. Therefore, weeds 1e, 1e can be prevented from growing weeds and the like, and good growth of seedlings can be promoted.
[0018]
7 (A) and 7 (B) show another example of the scraper body, and the earthwork body 57 is configured as the scraper body 58 in which a spiral body is wound around the inner peripheral surface of the scraper plate 55. You can also.
Each of the skin substitutes 5a to 5d configured as described above can efficiently plant the seedlings while backfilling the traces 1e and 1e in front of each rear planting claw 62, thereby planting seedlings. Can be performed satisfactorily.
[0019]
The bone marrow simultaneous transplanting machine A configured as described above lowers the planting device 6 via the elevating mechanism 3 by operating the operation lever 9L on the side of the driver's seat in the cultivated and watered field, While driving the substitute working machine 5 with the hydraulic motor 51, the surface of the paddle is leveled, and then the float 7 is slid to the ground, and the planting part 62 and the seedling stage 61 are extended from the traveling machine body 1 side. By driving with the drive shaft 8, seedlings can be planted at the same time while performing replacement.
[0020]
The planting device 6 can smoothly perform the rolling operation around the rolling support shaft 31 (FIG. 3), and can perform deep planting of seedlings by the planting claws 62 located on both outer sides of the planting device 6. Planting work that prevents shallow planting can be performed well.
In such a planting simultaneous planting operation, the trace 1e (FIGS. 6 and 7) deeply formed in the rear wheel 1b in a wet paddy field or the like has an interval L including the trace 1e in the substitute working machine 5. When the ground is leveled by the earthing body 57 provided in the diagonal direction on the pair of scissors 5a, 5b and the scissors 5a, 5c, etc., which are disposed on the side of the interval L The traces 1e and 1e can be backfilled by scraping the mud of the surface layer.
[0021]
And the ruins 1e, 1e backfilled by the floats 70, 70 arranged behind this can be leveled and finished to the same extent as other ground.
[0022]
【The invention's effect】
The present invention configured as described above has the following effects.
With the scrapers 5a to 5d, which are further arranged on the rear side of the wheel 1b of the traveling machine body 1 in an oblique direction, the ground is leveled and the seedling is planted smoothly by the planting device, The trace 1e can be easily backfilled by each of the scrapers 5a to 5d arranged with the interval L including the trace 1e. The backfilled trace 1e is further leveled by the rear float 7, so that the field scene can be finished cleanly.
[0023]
Therefore, weeds and the like can be prevented from growing on the raised trace 1e, and good growth of seedlings can be promoted.
