A plurality of rotor-like scraping bodies 5a to 5d as a scraping machine 5 to be described later are arranged at intervals on the rotating shaft 50, and a driving device 51 for driving the rotating shaft 50 to rotate. Is a small and large output hydraulic motor 5
1 is used. The hydraulic motor 51 is compactly mounted and driven while being housed within the working width formed by the above-mentioned scraping machine 5, and immediately before the seedlings are planted by the planting claws 62 of the planting device 6, In addition, the planting work can be satisfactorily performed by flattening the soil, and a rut track 1e of the rear wheel 1b can be satisfactorily eliminated and leveled by a configuration described later.

Further, as shown in FIG. 3, the planting device 6 places the center of the single-row float 71 and a planting claw 62 associated therewith behind the extension of the axis P of the rolling support shaft 31 as shown in FIG. I have arranged. The rotating shaft 63a pivotally supported in the transmission case 63 is separated from the rolling support shaft 31 by a predetermined distance H to the right and provided in the input unit case by the drive shaft 8 driven from the traveling machine body 1 side. The bevel gears 8a and 8b are rotated and driven to reciprocate the seedling mounting table 61 in the left-right direction and the seedling claw 62 is seeded.

Next, a detailed structure of the scraping machine 5 will be described with reference to FIGS. 3, 5 and 6. FIG. As shown in FIG. 5, a rotary plate 50 shown in FIG. Hollow cage-shaped rotor-shaped scraping bodies 5a to 5d are arranged and connected to scrape the soil so that the ground can be scraped flat.

The basket-shaped scraping bodies 5a to 5d have different lengths on the abscissa, and the rotating axes are individually spaced at intervals so that a predetermined range in front of each planting claw 62 can be scraped. The substitute working unit 5 is constituted by being mounted on the shaft 50. That is, as shown in FIGS.
a, 5a are arranged on both outer sides, and the next-length scraping bodies 5b, 5c are arranged inside the scraping bodies 5a, 5a between the mounting intervals of the support arm 66. The shortest scraping body 5d is placed on the right side of the driving device 51, and the center line of the scraping body 5d is provided so as to coincide with the center line C of the center float 71.

The pair of scratching bodies 5a and 5b and the pair of scratching bodies 5a and 5c are located behind the left and right rear wheels 1b.
A space [L] for backfilling and erasing the tracks 1e, 1e formed on the ground by the left and right rear wheels 1b, 1b is provided using the mounting space of the support arms 66, 66. Then, as shown in FIG. 5, mud and mud flow (hereinafter referred to as mud) at the time of the scraping are brought to the rut marks 1e, 1e side on the adjacent scraping bodies 5a and 5b and the scraping bodies 5a and 5c. A burrow 57 for backfilling is provided.

In the basket-shaped scraping body 57, the muddy soil or the like is moved between the adjacent scraping plates 55, 55, slightly inside the tip from the tip of the basket-like scraping body, and the muddy soil is moved to the rutted trace 1e side. A mulling body 57 made of a plate piece to be moved is provided so as to be inclined in a bridging manner, and as a result, as shown in FIG. 6, a pair of scraping bodies 5a and 5b which rotate in the direction of the arrow as the body advances.
And the scraping bodies 5a and 5c, while favorably scratching the rice field,
By the action of the sloping burrow 57 provided on the slope, the mud or the like on the surface layer can be buried in the space L side to fill the rut marks 1e, 1e. In addition, the soil scrapers provided on the scraping bodies 5a and 5b and 5c and 5a are inclined with respect to each other such that the soil is scraped toward the ruins 1e and 1e by the scraping bodies 5a to 5d rotating in the same direction. The direction is reversed.

Next, as a result of pressing the uneven soil surfaces of the buried ruins 1e, 1e by the floats 70, 70 arranged at the rear, the ruts are placed on the field scene where the seedlings are planted by the planting device 6. A flat rice field can be finished without leaving a large mark 1e. Therefore, the raised track 1
It is possible to prevent weeds and the like from growing on e and 1e, and to promote good breeding of seedlings.

FIGS. 7 (A) and 7 (B) show another example of a scraping body, in which a clay body 57 is formed on a scraping body 58 in which a spiral body is wound around the inner peripheral surface of a scraping plate 55. It can also be configured. Each of the scraping bodies 5a to 5d configured in this way effectively scratches the planting strip portion while backfilling the ruins 1e, 1e in front of each of the rear planting claws 62 to plant seedlings. Can be performed favorably.

Simultaneous Transplanting Scraper A Constructed as Above
Operates the operating lever 9L on the side of the driver's seat in the cultivated and irrigated field, thereby lowering the planting device 6 via the elevating mechanism 3, and causing the hydraulic motor 5
The float 7 is slid on the ground surface while the paddy surface is raked while being driven by 1 and the planting unit 62 and the seedling mounting table 61 are driven by the drive shaft 8 extended from the traveling machine 1 side. In addition, planting of seedlings can be performed at the same time while scratching.

The planting device 6 includes a rolling support shaft 31.
The rolling operation centering on (FIG. 3) can be smoothly performed, and the planting claws 62 located on both outer sides of the planting device 6 can be obtained.
Planting work that prevents the deep or shallow planting of the seedlings by the plant can be satisfactorily performed. In such simultaneous scraping and planting work, in a wet field or the like, a rut mark 1e (FIGS. 6 and 7) formed deeply by the rear wheel 1b has an interval L including the rut mark 1e in the substitute work machine 5. When the ground is leveled by the dirt body 57 provided diagonally on the pair of scraping bodies 5a, 5b and 5a, 5c, etc. Rut marks 1e, 1e can be backfilled by scraping the surface mud or the like.

Then, a float 70,
The track marks 1e, 1e backfilled by 70 can be flattened and finished to the same degree as the other ground.

[0022]

According to the present invention, the following effects can be obtained by the configuration described above. Behind the wheels 1b of the traveling body 1,
Further, the scraping bodies 5a to 5d in which the clay body 57 is arranged obliquely
In this way, the ground is leveled, so that the seedlings can be planted smoothly by the planting device, and the traces 1e are easily filled with the scraping bodies 5a to 5d arranged at intervals L including the traces 1e. Can be returned. Then, the backfilled rut trace 1e is further flattened by the rear float 7, so that the field scene can be finely finished.

Therefore, it is possible to prevent weeds and the like from growing on the raised ruins 1e, and to promote good breeding of seedlings.
