【考案の詳細な説明】
この考案は、耕耘ローターの耕耘刀に関するも
のである。[Detailed description of the invention] This invention relates to a tilling blade with a tilling rotor.
従来の耕耘ローターにおいて、多く使用されて
いるナタ爪と云われる耕耘刀では、土壌への喰込
みが悪く、殊に粘土質の硬い圃場では深耕するこ
とがきわめて困難であつた。 The tilling knife called a machete, which is often used in conventional tilling rotors, does not dig into the soil well, and it is extremely difficult to till deeply, especially in hard clay fields.
この考案は、耕耘刀を土壌に対して打込み易い

ものである。 Further, to explain this invention in detail with reference to the embodiment shown in the drawings, a shows a tiller made of the band iron of this invention. The tiller knife a uses a band iron of the required length, for example, about 8 mm wide and 24 mm high, and has a mounting hole 2 drilled at the rear end of the straight blade base 1, and the front part of the blade base 1 is aligned with the center line c of the center drive type tiller.
The blade tip 4 is formed by bending the blade 4 at a right angle toward the inside of the blade 3, which is bent at a right angle toward the direction of rotation b of the tilling knife a. The tip of the blade 4 is preferably sharp. A spoon-shaped reversing plate 5 is bent in a crescent shape along the curved portion 3 and fixed to the inside edge of the curved portion 3 by welding 6 or the like.

The proximal ends of the foil tubes 8 are fitted into the protrusions on both sides, and pinned using a conventional method.
To do this, the tilling rotor constructed as described above is fitted with its cylindrical shaft 9 into the foil tube 8 with the front curved part 3 of the blade base 1 of each tilling claw a facing toward the center line c of the center drive type cultivator. At the same time, although not shown, the cylindrical shaft 9 is pinned to the foil tube 8, and the above-mentioned tilling rotor is connected to protrusions on both sides of the drive shaft supported at the lower end of the central transmission case of the center drive type cultivator. be.

た、耕耘〓土の反転性能も良好となるのである。 Next, to explain its operation, when a center drive type cultivator is driven, power is transmitted from each drive shaft on both the left and right sides of the transmission case 7 in the center to the cylinder shaft 9 via the foil tube 8, and the tilling rotors on both the left and right sides are driven. It is rotated in the direction indicated by arrow b in FIGS. 2 and 6. Thus, each cultivating knife a is formed into a curved portion 3 in which the front portion of the sword base 1 is bent inward, that is, at a substantially right angle in the direction of the center line c of the center drive type cultivator. Since the angle is deviated in the horizontal direction, a relatively wide tilling width B (see Figs. 1 and 3) can be obtained for each tilling knife a compared to conventional hatchet claws. 〓
The soil is plowed roughly, which helps promote soil weathering. In addition, each cultivation sword a
The tip portion 4 of the blade is bent at a nearly right angle from the curved portion 3 toward the direction of rotation, so that the tip is almost on the circumference, making it possible to drive into the soil smoothly and with a small horsepower. Deep plowing work can now be carried out easily even in hard clay fields. Moreover, since a crescent-shaped spoon-shaped reversing plate 5 is provided on the inner edge of the curved part 3 of the tilling knife a, grass, straw, etc. that try to get entangled with the sword tip part 4 are guided along the reversing plate 5. Since the blade is pushed toward the blade base 1, their entanglement is prevented, and the blade tip 4 is always driven into the soil well, and the performance of turning the tilled soil is also good.

深耕作業を容易にならしめ得る効果がある。 According to this invention, it is possible to widen the tilling width of each tilling knife a, where the digging of each tilling knife a into the soil and the inversion crushing of the soil tilled by the inversion plate can be carried out well, and moreover, This has the effect of preventing soft materials from becoming entangled with the tip portion 4 and facilitating deep plowing work even in hard clay fields.
