Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scraping device in a scraping simultaneous planting machine for plowing a field in which grain culms are harvested, and for planting seedlings in the scraped part while shallowly scraping the surface layer. .

[0002]

2. Description of the Related Art Conventionally, a method of plowing a field in which grain culms are harvested and scratching the entire tillage layer and a method of planting seedlings in the field after harvesting grain culms in a non-tillage state, and There is already known a planting machine that cultivates only a narrow width of a field and plant seedlings in the cultivated part.

[0003]

Among the known planting methods, the first method requires a great deal of labor to scrape the entire tillage layer and is kneaded to a deep layer to eliminate voids in the soil. Moreover, it was necessary to perform additional planting work by the planting device after the scratching. In the second method, the field at the time of planting lacks levelness due to combine crawler marks and depressions at the time of harvest, and there are many old plants and weeds. It causes floating seedlings and poor growth. Furthermore, in the third method, it is difficult to keep the planted seedlings standing upright because the soil in the cultivated portion of the planted row is not sticky.

In order to solve such a problem, a plurality of plant bodies are laterally arranged at a rear portion of a traveling vehicle, and the plant bodies and the wheels immediately in front of them are forcedly arranged. When a rotary rotor was installed that was rotated and spread over the entire planting width, a large amount of mud was pushed out from both ends of the rotary rotor, so the planted seedlings could be pushed down.

[0005]

According to the present invention, a planting device having a plurality of planting bodies is arranged at the rear of a traveling vehicle, and three or more plants forcibly driven to rotate are provided at the front of the planting device. The above-mentioned problem was solved by arranging the horizontal stirrer rotors in the horizontal direction and placing the intermediate staggered rotors in front of those on both sides.

[0006]

[Operation] After plowing the harvested field, water is submerged, and in this state, the submerged rotor is advanced while rotating while invading the surface layer of the plowed soil. The plant progresses while shallowly scratching the surface layer, and immediately after that, a plurality of plantlets scrape the seedlings in the seedling table of the planting device one by one, and plant in the field that has been scratched. And
In the above-mentioned scraping stroke, the rear scraping rotor scrapes the field on the side of the portion where the front scraping rotor has scratched, and the mud extruded from both ends of the front scraping rotor is , Which is received by the side of the rear scraper rotor, part of which flows within the width of the rear scraper rotor, while the other part of the rear end of the rear scraper rotor is from the inner end of the rear scraper rotor. The scraping rotor flows out to the scraped portion, and flows backward from the other end of the scraping rotor at the rear part.

Further, the distance between the outer ends of the rear scraping rotor 21 is larger than the planting width of one stroke (planting strip interval L × planting strip number n), and both ends are the maximum as shown in FIG. It is designed to project by L / 2 + α from the outer planting strip.

In short, when the rear scraping rotor 21 is rotated and moved forward, the ridges 22 ... Repeat the action of alternately pushing the absorbed soil in the left and right directions, and
In the process, the width of the planted width will be scrubbed by adding α to both sides. Further, large-diameter disks 21a, 21a are attached to the outer end of the rear scraping rotor 21 to prevent the mud from flowing outward. Further, the bracket 23a fixed to the lower portion of the column 6a connecting the rear portion of the top link 6 has the rear scraping shaft 20 at the lower portion.
Support plate 23b installed upright on the gear case 23 supporting the

[0014] Next, the description will be given of the scraping and planting. After the rice was cut in the previous year, it is cultivated in the fall by a rotary tiller attached to the tractor, or for the convenience of work, it is cultivated in the next year. To do. As a result, the crawler traces and other irregularities of the combine harvester are eliminated at the time of harvest, and the cut straw shredded by the cutter at the time of harvest is plowed with the weeds. Then, if the soil becomes loose by flooding the cultivated field immediately before planting and allowing 2-3 days to elapse, introduce a scraping planter into the field to plant the planting device 8, When the front and rear scraping rotors 21b and 21 are driven and driven, the scraping rotors 21b and 21 rotate and proceed in a state of shallowly penetrating into the soil. At that time, the scraping rotors 21b and 2 are moved.
Each of the ridges 22 of 1 pushes the mud diagonally to one side at an inclined portion directed to one side, and the subsequent inclined portion directed to the other side pushes the mud diagonally to the other side, and Since the lateral extrusion is repeated, the cultivated soil is scratched well in a shallow area and the weeds, straws, old plants, etc. are pushed into the mud to level it, and the width of the scratches catches the mud pushed to the side. It is divided by the disks 21a, 21a on both sides.

In the above-mentioned scraping stroke, the scraping width is wider than the substantial planting width (planting strip interval L × strip number n) by α on both sides, so that in the next stroke, the scraping portion is larger. Only 2α will be wrapped, and when repeating back-and-forth scraping, there is no unscratched part left between strokes, and between the front part scraping rotor 21b and the left and right rear scraping rotors 21 and 21. In this case, no unscratched part is generated, and therefore, weeds do not proliferate in that part at an early stage, and unevenness does not remain in the field scene. In addition, the layers deeper than the part that has been scratched remain cultivated. Further, since the center float 16a is located immediately after the front scraping rotor 21a, the ground pressure can be accurately detected without being affected by the mud scratched by the scraping rotor.

Immediately after such scraping, the planting device 8
In the same manner as the conventional one, the planting body 14 of No. 1 is planted in a portion where the seedlings in the seedling placing table 15 are scraped off one by one and planted in the scraped area. The nozzle 40 fertilizes the pasty fertilizer pumped into the fertilizer groove by the fertilizer pump 35 into the soil. The fertilizer is not limited to the paste fertilizer but may be granular fertilizer. At the time of the above-mentioned scratching of the weeds, weeds, old plants or straws are pushed into the mud, so that the planting can be carried out well and the growth of the weeds can be suppressed, and,
The lower layer than the shallow substratum is in the cultivated state and has many small voids, so oxygen supply to the roots and root elongation are improved, and seedling growth is also promoted. Note that the scraping rotor 21 can also be rotated in the reverse direction (the lower surface is rotated forward) or can be rotated in the forward direction.

[0017]

According to the present invention, a planting device 8 having a plurality of planting bodies 14 is arranged in the rear part of the traveling vehicle 1, and three or more plants are forcedly driven in the front part of the planting device 8. Since the sub-scraping rotors are arranged in the lateral direction and the middle sub-scraping rotor is placed in front of the ones on both sides, the sub-scraping and planting can be performed in one working step, which can significantly improve the working efficiency. it can. Also, since only the surface layer is scratched by the scratching rotor, sufficient scratching can be performed in one stroke and the lower layer is in a state without scratches with many voids, improving the growth environment of the crop. You can

Moreover, since the mud scraped out from the front scraping rotor 21b flows from both ends thereof to the space between the rear scraping rotors 21 and 21 on both rear sides, only the outer ends of the rear scraping rotors 21 and 21. The rear scraping rotors 21 and 21 are not discharged from the rear part and are partially separated from each other on the left and right sides.
It will disperse and flow from both ends, and will not push down already planted seedlings.
