BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a substitute scraping rotor in a simultaneous scraping planting machine for cultivating a field where grain culms have been harvested, and planting seedlings in a portion where the surface layer has been shallowly scratched. .

[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 replace the entire plowed layer, and is kneaded deep to eliminate the 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 traces of crawlers and depressions of the combine at the time of harvesting, which lacks uniformity, and since 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 was scratched shallowly, and seedlings were planted on the scratched portion. The scraping rotor provided at the front part of the planting device rotated and scratched. At this time, there is a new problem that the muddy water flowing laterally from both ends of the substitute rotor pushes down the seedlings planted laterally.

[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, a rotatable rotatable rotor is supported in the lateral direction, and ridges bent to the left and right are provided on the outer peripheral surface excluding both sides of the rotatable rotor. The above-mentioned problem has been solved by providing a spiral ridge that guides muddy water while guiding it to the center side so as to suppress the muddy water from flowing to both sides.

When 1 rotates, spiral ridges 22a are formed to project muddy water to the center side and perform a scraping action. The protruding ridges 22 may be formed by intermittently arranging those bent in a V-shape, or by intermittently arranging those that are inclined left and right. In addition, substitute rotor 2
The length of one is longer than the planting width of one stroke, and both ends are
It projects slightly from the outermost planting strip.

Next, the transmission will be described. The PTO shaft protruding rearward from the transmission case 5 drives the input shaft of the planting device 8 via the intermediate shaft and the extendable universal joint 9 and is attached to the drive shaft 28. The sprocket 30 drives a sprocket attached to the input shaft of the reduction gear 29, and when a shift lever 32 provided on the rear side of the driver's seat 31 is operated, the gear is changed and the output shaft 34 of the reduction gear 29 is shifted. The output shaft 34 is provided at an intermediate portion of the substitute shaft 20 via a telescopic universal joint 33.

[0010] Next, a description will be given of the sowing and planting. 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 traveling is performed while driving the substitute rotor 21, the substitute rotor 21 advances in a state of shallowly penetrating into the soil while rotating, and at this time, each of the ridges 22 on both sides of the substitute rotor 21. Pushes the mud diagonally to one side with the slope toward one side, and the subsequent slope toward the other side pushes the mud diagonally to the other side, and such an opposite side extrusion is repeated. The cultivated soil is well scraped in a shallow area, and weeds, straw and old plants are pushed into the mud and leveled at the same time. In addition, the spiral ridges 22a on both sides guide muddy water and mud to the center side of the machine width while rotating and scraping, so that the amount of muddy water pushed outward is reduced, whereby The muddy water does not push down the seedlings planted on the ground.

On the side of the seedling to be planted, the fertilizer nozzle 40 applies fertilizer to the fertilizer groove formed by the rotating disk in the soil with the paste fertilizer pumped by the fertilizer pump 36. 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.
