본 고안은 로타리용 경운기날의 결합 구조에 관한 것으로서, 특히 경운기 날의 유동이 없이 견고하게 고정되도록 결합부의 구조를 마름모꼴로 형성하면서 경운기날의 설치 및 교체 시간을 단축시키기 위해 고정핀의 구조를 개선한 것이다.The present invention relates to a coupling structure of a rotary tiller blade, in particular, to improve the structure of the fixing pin to shorten the installation and replacement time of the tiller blade while forming the structure of the coupling portion so as to be firmly fixed without the flow of the tiller blade. It is.

종래에는 도면 제 4 도에 도시된 바와같이, 공지의 로타리용 경운기축의 외주연에는, 내측에 사각 형태의 삽입부(11')가 형성된 취부홀더(10')가 일정 간격으로 배일 설치되었고, 상기 삽입부(11')에 삽입토록 자루부(21')의 단면 또한 사각형태로 형성된 경운기날(20')을 고정볼트(23')로서 결합 설치하였다.Conventionally, as shown in FIG. 4, on the outer circumference of a known rotary tiller shaft, a mounting holder 10 'having a square insert portion 11' formed therein is provided at regular intervals. The tiller blade 20 ', which has a cross section of the bag portion 21' to be inserted into the inserting portion 11 ', also has a rectangular shape, and is installed as a fixing bolt 23'.

그러나 이는, 사각형태의 삽입부에 자루부의 단면이 동일한 경운기날을 삽입하고 이를 고정볼트로서 체결 설치하여 사용하므로서, 사용시 발생되는 진동에 의해 고정볼트가 이완되어 취부홀더내에 삽입된 경운기날에 유동이 발생하게 되어 계속되는 작업으로 인하여 취부홀더가 번형되면서 경운기날이 파손되거나 빠져달아나게 되는 문제점을 지니고 있었으며 이를 예방하기 위하여 수시로 고정 볼트로 조여주어야 하는 번거로움이 뒤따랐다.However, this is because, by inserting the tiller blade having the same cross section of the bag portion into the rectangular insertion portion and fastening and installing it as a fixing bolt, the fixed bolt is relaxed by the vibration generated during use, so that the flow of the tiller blade inserted into the mounting holder is removed. As a result of the continuous work, the mounting holder was breached, so that the tiller blade was broken or escaped. To prevent this, it was necessary to tighten the fixing bolts from time to time.

또한 주기적으로 경운기날을 교체시에는, 이들의 결합이 고정볼트로 체결되어 있으므로해서 별도의 공구로서 분해조립시켜야 하므로서 그에 상응하는 교체시간이 지연되는 문제점을 안고 있었다.In addition, when replacing the tiller blades periodically, these combinations are fastened with fixed bolts, so that they have to be disassembled and assembled as separate tools, thereby having a corresponding replacement time delay.

따라서, 본 고안은 취부홀더에 경운기날을 간단한 동작으로 견고하게 고정 설치할 수 있도록 경운기날의 자루부와 그와 상호 삽입설치되는 취부홀더를 마름모꼴로 형성하면서, 스토퍼가 절첩 가능토록 힌지 결합된 고정핀으로서 고정 설치하기 위한 것이다.Therefore, the present invention forms a bag holder of the tiller blade and a mounting holder inserted into each other so that the tiller blade can be firmly fixed to the mounting holder in a simple operation, while the stopper is hinged so that the stopper can be folded. It is intended for fixed installation.

이를 첨부된 도면에 의하여 보다 상세히 설명하면 다음과 같다.When described in more detail by the accompanying drawings as follows.

즉, 경운기축(100) 외주연에 일정 간격으로 경운기날(20)이 삽입 설치되도록 복수개의 취부홀더(10)가 배열 설치된 통상의 것에 있어서, 상기 취부홀더의 삽입부(11)와 삽입부에 삽입 설치될 경운기날(20)의 자루부(21) 단면을 마름모꼴로 형성하였으며, 선단부에 절첩 가능한 스토퍼(24)가 힌지 결합된 고정핀(23)으로서 상기 경운기날(20)이 삽입 설치된 취부홀더(10)를 관통하여 착탈식으로 결합설치 한 것이다.That is, in a conventional installation in which a plurality of mounting holders 10 are arranged so that the tilling blades 20 are inserted at predetermined intervals on the outer periphery of the tiller shaft 100, the insertion portion 11 and the insertion portion of the mounting holder are arranged. A cross section of the sack portion 21 of the tiller blade 20 to be inserted is formed into a rhombus, and the mounting pin 23 is hinged to the stopper 24 that is foldable at the distal end. (10) penetrated detachably installed.

이와같이 구성된 본 고안의 작동상태를 설명하면 다음과 같다.Referring to the operating state of the present invention configured as described above are as follows.

경운기날의 교체 및 배열 교체시에 경운기축(100) 외주연에 일정 간격으로 배열 설치된 복수개의 취부홀더(10) 내측으로 자루부(21)의 단면이 마름모꼴(도면 제 3 도 참조)로 형성된 경운기날(20)을 삽입하고, 선단부에 스토퍼(24)가 절첩토록 힌지 결합된 고정핀(23)의 스토퍼(24)를 고정핀 몸체와 수평위치에 놓은 상태에서 취부홀더(10)의 삽입공(12)과 경운기날의 삽입공(22)을 일치시키면서 상기 고정핀을 삽입한후 고정핀의 스토퍼(24)를 힌지핀(25)을 중심으로 90°회전시켜 고정핀(23)과 수직하게 위치시키므로서 경운기날(20)을 취부홀더(10) 내측에 고정 설치하는 것이다.When the cultivator blade is replaced or replaced, the cultivator having a cross section of the bag 21 having a rhombus shape (see FIG. 3) inside the plurality of mounting holders 10 arranged at regular intervals on the outer circumference of the tiller shaft 100. Inserting the blade 20, the insertion hole of the mounting holder 10 in a state in which the stopper 24 of the fixing pin 23 hinged so that the stopper 24 is hinged to the distal end thereof in a horizontal position with the fixing pin body ( 12) and the insertion pin 22 of the tiller blade coincides with the fixing pin, and then the stopper 24 of the fixing pin is rotated 90 ° about the hinge pin 25 to be positioned perpendicular to the fixing pin 23. By doing so, the tiller blade 20 is fixedly installed inside the mounting holder 10.

이와같이 결합된 상태에서 로타리 작업을 실시하게 되면 경운기날에 작용하는 하중의 방향이 도면 제 2 도의 "W"방향 즉, 고정핀(23)의 수직방향으로 하중이 작용하게 되어 삽입부(11)의 형상이 마름모꼴로 형성된 취부홀더(10) 내측에 삽입될 경운기날의 자루부(21)의 단면이 상기 취부홀더(10) 삽입부(11)와 동일토록 형성되어 하중이 고정핀(23)의 수직방향으로 작용하게 되므로 취부홀더(10)의 내측에 삽입될 경운기날의 자루부(21)가 쇄기 작용을 하게 되어 취부홀더(10)의 내측에서 경운기날(20)이 견고하게 고정되는 것이다.When the rotary work is carried out in such a coupled state, the load acts on the tiller blade in the direction of “W” in FIG. 2, that is, the vertical direction of the fixing pin 23. The cross-section of the bag portion 21 of the tiller blade to be inserted into the mounting holder 10 having a rhombus shape is formed to be the same as the inserting portion 11 of the mounting holder 10 so that the load is perpendicular to the fixing pin 23. It acts in the direction so that the sack portion 21 of the tiller blade to be inserted into the mounting holder 10 has a wedge action so that the tiller blade 20 is firmly fixed inside the mounting holder 10.

또한, 장기간 사용으로 취부 홀더의 내측 삽입부(11)와 경운기날의 자루부(21)가 마모되어도 경운기축(100)의 회전에 의한 하중으로 인하여 경운기날의 자루부(21)는 취부홀더의 삽입부(11)내에서 쐐기작용으로 더욱 강력하게 고정되는 것이다.In addition, even if the inner insertion portion 11 of the mounting holder and the sack portion 21 of the tiller blade wear out due to prolonged use, the sack portion 21 of the tiller blade may not be attached to the mounting holder due to the load caused by the rotation of the tiller shaft 100. It is more strongly fixed by the wedge action in the insertion portion (11).

이와같은 본 고안은 경운기날의 결합구조가 쐐기 작용으로 고정토록 형성되었기 때문에 경운기날과 취부홀더의 결합부가 마모되어 조그만 틈새가 생기더라도 경운기축의 회전으로 인한 수직하중으로 인하여 쐐기작용이 이루어져 항상 진고하게 고정되므로해서, 경운기날의 유동이 발생치 않아 작업능률을 향상시킴은 물론이고 경운기날과 취부홀더의 변형 및 파손을 방지할 수 있으며, 선단부에 절첩 가능한 스토퍼를 힌지 결합시킨 고정핀을 사용하므로서 별도의 분해공구가 필요없이 간단한 조작으로 경운기날의 교체를 용이하게 할 수 있어서 종래의 문제점을 완벽하게 해결하는 매우 실용적인 고안이다.The present invention has been formed so that the coupling structure of the tiller blade is fixed by the wedge action, so that the wedge action is always firmly made due to the vertical load due to the rotation of the tiller shaft, even if a small gap occurs due to the wear of the joining part of the tiller blade and the mounting holder. As it is fixed, the flow of tiller blade does not occur, which improves work efficiency and prevents deformation and breakage of tiller blade and mounting holder, and by using a fixing pin that hinges the foldable stopper at the tip. It is a very practical design that completely solves the conventional problems since it is possible to easily replace the tiller blade with a simple operation without the need for the disassembly tool.
