BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scraping rotor of a simultaneous sowing machine for cultivating a field where a culm is harvested, and planting seedlings in a portion where the surface layer is soaked while shaking. .

[0002]

2. Description of the Related Art Conventionally, a method of cultivating a field where grain culms have been harvested and substituting the entire tillage layer, and a method of planting seedlings in a field after harvesting grain culms in a non-tillage state, A planting machine that plows only the narrow width of the above-mentioned field and plant seedlings in the plowed portion is already known.

[0003]

Among the above-mentioned known planting methods, the first method requires a great deal of labor to scrape the entire cultivated layer, and is kneaded to a deep layer to eliminate voids in the soil. Moreover, after the scraping, the planting operation must be separately performed by the planting device. Further, the second method is that, in the field at the time of planting, there are crawl marks and pits of a combine at the time of harvesting, which lacks uniformity, and because there are many old plants and weeds, remarkable deep planting or shallow planting is performed. Floating seedlings and poor growth occur. Furthermore, in the third method, it was difficult to stand and maintain the planted seedlings because the soil at the cultivated portion of the planting row was not sticky. In order to solve such a problem, the surface layer of the plowed field is scratched shallowly, and when seedlings are planted on the scratched portion, the scraping rotor provided at the front of the planting apparatus rotates and scratches. At this time, a large amount of muddy water accumulates over the entire front portion of the substitute rotor to inhibit rotation of the substitute rotor, and flows out to the side to push down the planted seedlings.

[0004]

According to the present invention, there is provided a planting device having a plurality of planting bodies arranged laterally at predetermined planting strip intervals at the rear of a traveling vehicle. At the front of the planting device, the scraping rotor is supported in a horizontal direction, and a number of circumferential grooves are provided on the outer peripheral surface of the scraping rotor at intervals in the length direction. The above-mentioned problem was solved by providing the bent ridges in such a manner that muddy water flows backward from the circumferential groove.

After harvesting the rice in the previous year, plowing with a rotary tilling device attached to a tractor in the autumn, or plowing the following year if it is convenient for work. I do. This eliminates the crawler marks and other irregularities of the combine at the time of harvesting, and the straw that has been shredded and spread by the cutter at the time of harvesting is thrown in together with the weeds. Then, immediately after planting, if the soil becomes soft and soft by flooding the cultivated field for 2 to 3 days, a simultaneous scratching planting machine is introduced into the field, and the planting device 8 When the substitute scraper 21 is driven and driven to travel, the substitute substitute rotor 21 advances while rotating and penetrates into the ground shallowly. At this time, each of the ridges 22 of the substitute substitute rotor 21 removes mud. The slanting part toward the side pushes diagonally one side, and the slope toward the other side that follows pushes the mud diagonally to the other side, and such reverse side extrusion is repeated, so the cultivated soil is shallow. Weeds, straw and old plants are pushed into the mud and are leveled at the same time as they are well scraped in the area.

A plurality of plantings 14 immediately following the scraping rotor 21 are provided with one seedling in the seedling table 15 at a portion where the overhanging portion at the front of the leveling float 16 is leveled. Scrape and plant each plant. At this time, a large amount of muddy water is pushed out and tends to accumulate at the front part of the rotating scraping rotor 21, but a part of the muddy water is in each of the circumferential grooves 21 a.
・ Because it flows backward, the rotation of the scraping rotor 21 is not hindered, and the amount of muddy water flowing from both ends of the scraping rotor 21 to the left and right sides is reduced, so that it is planted on the adjacent land. Do not push down the seedlings that have been killed. When the muddy water guide plates 25 are provided on the outer sides of both ends of the substitute rotor 21, the seedling lodging prevention effect can be further improved.

Further, on the side of the seedling to be planted, the fertilizing nozzle 40 fertilizes the soil with the paste fertilizer pumped by the fertilizing pump 36 in the fertilizing groove formed by the rotating disk. The fertilizer is not limited to the paste fertilizer, but may be a granular fertilizer. At the time of the above-mentioned shallow weeding, since weeds, old plants, cut straw, etc. are pushed into the mud, it is possible to plant well and to suppress the growth of weeds. Since the lower layer is plowed and has many small voids, the supply of oxygen to the root and the elongation of the root are improved, and the growth of the seedling is promoted.
