DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a planting apparatus for a simultaneous sowing planting machine for cultivating a field where grain culms have been harvested, and for planting seedlings in the shaved area while shallowly scratching the surface. .

[0002]

2. Description of the Related Art Conventionally, a method of cultivating a field where grain culms have been harvested and planting seedlings by scratching the entire cultivated layer, and a method of cultivating seedlings in a field after harvesting grain culms in a non-plowed state. Planting method,
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 replace the entire cultivated layer, and is kneaded to the deep layer to eliminate voids in the soil. Moreover, after the scraping, a separate planting operation has to be performed by a planting device having a seedling mounting table, a plurality of plantings, and a leveling body (leveling float) . 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. Such problems shallow Dai掻the surface of the field that caused tillage to solve, where was successively planted seedlings while reciprocating body to the Dai掻unit content, leveling member between planting stroke before and after (leveling float) A part where the leveling is not performed is caused, and this part has irregularities, and since the weeds and the like are exposed without being pushed in, the place where the irregularities are high, and the exposed weeds are planted for a short time after planting. They prospered and inhibited the growth of the seedlings.

[0005]

The harvested field is plowed after being plowed, and the scraping rotor is advanced while rotating in a state in which the scraping rotor is laterally penetrated into the surface layer of the cultivated soil. The soil on the surface layer is scraped to make it muddy, and the terrain of the planting equipment is laid down to the rear of the raked rotor and to the outer side of the raked rotor. The seedlings on the mounting table are scraped by one plant at a time, and planted in the site where the leveling body has been leveled. And since the leveling body on the side part is leveled to the outside from the end of the scraping rotor, there is no unleveled part between the preceding and following scraping planting processes, and therefore, the scraping and planting are performed at the same time. There are no noticeably high parts or weeds that are not pushed into the mud in the field scene after the operation.
