Abstract

<P>PROBLEM TO BE SOLVED: To solve problems that each rotary blade formed into a curve having a tip of the rotary blade symmetrical right and left and different shapes cannot be mounted irrespective of the right and left and welding repair is impossible by 99% because most of the material of the blade is a quenched material. <P>SOLUTION: The single part structure of the rotary blade is improved into a fan-shaped and belt-like conical surface form. The rotary blade is mounted at a tilt angle of a desired angle without the same mounting angle of each case 12 for receiving blades in a shaft stem 11 as that in a plane in the rotative direction of the shaft stem. A plurality of single part improved blades are used and the whole is improved into a coupling type rotary blade in which the integrated structure is provided in a coupled state by parallel connection. Thereby, the epoch-making coupling type rotary blade designed to replenish and couple the unused belt-like rotary blade of a conical surface form in the coupled state by the parallel connection at the un-abraded rear end without even 1% disposal when about 30% of the tip is eliminated by stirring and abrasion. As a result, the plurality of common single part rotary blades without distinguishing right and left can alternately be fitted and coupled to a sheath-like case body and fitted and mounted on even the case 12 for the receiving blades with the tilt angle fixed to the shaft stem 11. Even when the tip 13 is eliminated by stirring and abrasion, the un-abraded rotary blade of a conical plate shape can be replenished and coupled to the un-abraded root side irrespective of the right and left. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention does not discard 1% of the remaining wear blades, and the shape and structure of a connected rotary blade that can be easily replenished regardless of whether the rotary blades are replenished, and the rotary blades are attached regardless of left and right. It relates to the structure of the shaft.

  In conventional rotary blades, almost only the tip is symmetrically formed in a curved shape with different curves, and only about 30% of the tip curve part is plowed and worn. Even if it disappears, the restoration repair of this wear disappeared part cannot be repaired due to the different shape structure with symmetrical left and right curved directions and complicated curved shape, and naturally the remaining unworn About 70% of the root side cannot be recycled and can only be disposed of, and its economic loss is great and environmentally problematic.

  In addition, the conventional rotary blade is curved in different shapes symmetrical on the left and right, has directions on the left and right, and could not be attached regardless of the left and right. For this reason, it is necessary to orderly install the left and right separately. If the mounting order is incorrect, there is a problem in that the soil surface after tillage does not become flat.

  FIG. 30 is a side view of a conventional rotary blade in which a conventional rotary blade (35) is fitted into a conventional receiving blade case (64) provided on a shaft shaft (11) and fixed with a fixing bolt (41). FIG. As shown in the drawings, conventional rotary blades are almost single blades and cannot be repaired or refilled.

FIG. 31 is a front view of a one-piece conventional rotary blade fixed at a substantially right angle to the shaft axis (11) as shown in the drawing.

In the conventional rotary blade, as described above, the tip of the conventional rotary blade is formed in a curve having a symmetrical shape and a different shape, and it is impossible to attach regardless of the left or right, Since most of these materials are also hardened, welding repair was impossible 99%.
In addition, because of the structure and form, it is impossible to replenish and connect the rotary blades regardless of the left and right, and there is also a problem with the disposal of the rotary blades that are worn out and about 70% remain. It was.

  In order to achieve the above object, the structure of the replenishment type rotary blade according to the present invention has a single blade structure having a conical surface shape like a fan tip and a belt shape, and has the same shape as the inside. A plurality of case bodies forming a round cavity are used in a parallel connection form to form an integrated and converging connection type rotary blade structure that can be fitted and connected regardless of the left-right direction; and The most important feature is that the case structure for the receiving blade on the shaft shaft to which the coupling type rotary blade is attached has a predetermined tilt angle that is alternately symmetrical with respect to the angle other than the rotation direction surface of the shaft shaft. And

Even if the tip part disappears due to stirring wear, it is not worn regardless of left and right An unworn conical rotary blade can be replenished and connected to the base side.

  The second effect is that the shape is the same on the left and right, and it is possible to replenish and connect without distinguishing between the left and right.

  As a third effect, since it is not a disposable type like the conventional one, it can be used to the end without being 100% discarded, so it is also good for global environmental problems.

  The fourth effect is that the shape is the same on the left and right, and mass production by press molding is possible.

  As a fifth effect, since the shape is simple, it can be used not only for agricultural purposes but also for other uses for stirring.

  The sixth effect is that since the blade has a strip-shaped conical plate, it can be attached so that the cutting edges cross each other, making it easy to completely stir the agitated material. Is possible.
