본 고안은 경운기용 로타리형 쇄토기의 써래발 결합장치에 관한 것으로, 경운기용 로타리축에 형성된 삽입구에 써래발을 삽입하여 완강히 결착시켜 주므로 써래발이 사용중 흔들리지 않게하고, 또 써래발 각도를 항상 일정한 상태로 유지시켜 땅을 골고루 깊이 파헤쳐 줄 수 있도록 함을 목적으로 한 것이다.The present invention relates to a harrow foot coupling device of a rotary tiller for tiller, and inserts the harrow foot firmly into the insertion hole formed in the rotary shaft of the tiller so that the harrow foot is not shaken during use and the harrow foot angle is always constant. It aims to be able to dig deeply evenly through the ground.

종래에는 쇄토기의 써래발을 로타리축에 형성된 삽입구에 삽입하여 단순히 볼트와 너트로 결착하였기 때문에 작업중 로타리축의 회전에 의해서 조임너트가 쉬풀리게 되거나, 또는 완강하게 결착되지 못하여 써래발이 사용중 유동되어 삽입구가 넓어지게 되거나 파손되어 써래발이 더욱 많이 흔들리게 되며, 이에 따라 경운기를 멈춘 후 풀린 조임너트를 다시 조여 주어여 하는 불편은 물론 작업시간의 낭비를 초래하였고, 또 이와같이 작업중에 발생되는 불편을 감안하여 그냥 작업을 계속하면 흔들리는 써래발은 각도가 일정치 않게되므로 땅을 깊이 파헤쳐 주지 못하게 되므로 곡식은 깊이 뿌리를 내리지 못하여 죽거나, 곡식이 잘 영글지 않아 풍성한 수확을 얻을수가 없었다.Conventionally, since the foot of the harrow was inserted into the insertion hole formed in the rotary shaft and simply fastened with a bolt and a nut, the tightening nut was loosened due to the rotation of the rotary shaft during operation, or the shaft could not be firmly fixed so that the insertion hole was flowed during use. The foot is widened or damaged, causing the paw to shake more. Accordingly, after stopping the cultivator, it is not only the inconvenience of tightening the loosening nut again, but also a waste of working time. As you continue to work, the swaying paws will not be able to dig deep into the ground as the angle will be uneven, so the grain will not be deeply rooted, or the grain will not be so young that you will not get a rich harvest.

또한 이때문에 써래발을 로터리축에 납땜하여 일체가 되게 고정시킨 경우도 있으나, 이 경우에는 써래발을 교체하기 위해서는 로타리축까지 모두 교체해야 되므로 비경제적이었다.For this reason, it was sometimes economical because the rotor foot was soldered to the rotary shaft to fix it integrally. However, in this case, the rotary shaft had to be replaced to replace the rotary foot.

본 고안은 이와같은 점들을 해결하고자 고안한 것으로 첨부된 도면에 의하여 그 구조 및 사용상태를 설명하면 다음과 같다.The present invention has been devised to solve these points, and the structure and use state will be described with reference to the accompanying drawings.

경운기용 로타리축(1)에 다수 형성한 각 삽입구(101)에 써래발(2)을 각각 삽입하여 볼트와 너트로 결착토록 함에 있어서, 상기 각 삽입구에 뚫으는 볼트공(101')은 직사각형상으로 길게 뚫고, 써래발(2)의 삽입부(201)도 볼트공(202)을 직사각형상으로 길게 뚫어주며 양쪽에는 레이퍼형의 돌편(203)을 형성하여 상기 삽입부(201)를 삽입구(101)에 삽입하여 볼트공(101')(202)들이 서로 통하게한 다음 이들을 관통하게 나선봉이 두부의 일측으로 편심되게 성형한형상의 볼트(3)와 ""형상의 쇄기(4)를 삽입하여 공지의 너트(5)로 체결하여 결착토록 한 것이다.In each insert hole 101 formed in a plurality of rotary shafts 1 for tiller to insert the harrow feet (2), respectively, to be bound by bolts and nuts, the bolt holes (101 ') drilled in the respective insertion holes are rectangular Long hole, the insertion part 201 of the claw 2 also penetrates the bolt hole 202 in a rectangular shape and forms a raper-shaped protrusion 203 on both sides to insert the insertion part 201 into the insertion hole 101. ) And the bolt holes 101 'and 202 pass through each other, and then spiral rods are eccentrically formed to one side of the head to penetrate them. Shaped bolts (3) and " "Into the shape of the wedge 4 is fastened with a known nut (5) to bind.

이와같이 구성된 본 고안의 사용효과를 보다 상세히 설명하면 다음과 같다.Referring to the effects of the present invention configured in this way in more detail as follows.

본 고안은 제2도에서 보는 바와같이 결착하기 위해서는 먼저 로타리축(1)에 형성한 각 삽입구(101) 내부로 써래발(2)의 삽입부(201)를 삽입하여 삽입구(101)의 삽입부(201)에 각각 뚫은 직사각형상의 볼트공(101')(202)들이 서로 통하게 한 다음 제2도(가)에서와 같이 쇄기(4)의 일단부가 볼트(3) 머리의 내면에 받쳐지도록 함께 상기 볼트공(101')(202)을 관통하게 기워서 볼트공(101')의 반대측으로 나오는 볼트(3)의 나선봉 단부에 너트(5)를 체결하여 조여주면 볼트(3)가 너트(5)측으로 당겨지게 되므로 이 볼트의 머리 내면에 받쳐지게 끼워진 쇄기(4)도 함게 너트(5)측으로 당겨져 이동하게 되는데, 이렇게 되면 쐐기(4)의 형상에 의해 써래발(2)의 삽입부(201)는 삽입구(101)의 내측으로 밀려 들어가게 된다.In the present invention, in order to bind as shown in FIG. 2, first, the insertion part 201 of the foot 2 is inserted into each insertion hole 101 formed in the rotary shaft 1, thereby inserting the insertion part 101. The rectangular bolt holes 101 'and 202 respectively drilled in the 201 are allowed to pass through each other, and then, together with the one end of the wedge 4 supported by the inner surface of the head of the bolt 3 as shown in FIG. Tighten and screw the nut 5 to the end of the spiral bar of the bolt 3 coming out from the opposite side of the bolt hole 101 'by tilting it through the bolt hole 101' and 202, and the bolt 3 becomes the nut (5). Since the wedge 4 is pulled toward the inner side of the head of the bolt, the wedge 4 is also pulled and moved to the nut 5 side, and the insertion part 20 of the harrow foot 2 is shaped by the shape of the wedge 4. ) Is pushed into the insertion hole 101.

이렇게 하여 제2도 (나)에서 보는 바와같이 삽입부(201)의 양측에 형성된 돌편(203)이 삽입구(101)의 외단에 밀착되는 상태가 될때까지 너트(5)를 조여주면 써래발(2)의 삽입부(201)는 삽입구(101)내에서 볼트(3)와 쇄기(4) 및 돌편(203)에 의해 완전 필착되게 꽉 끼여져 완강히 고정되는 것이다.Thus, as shown in (b) of FIG. 2, the nut 5 is tightened until the protrusions 203 formed on both sides of the insertion part 201 are brought into close contact with the outer end of the insertion hole 101. Insertion portion 201 of the) is inserted tightly by the bolt 3, the wedge 4 and the projection piece 203 in the insertion hole 101 is fixed firmly.

이와같이 조립을 하면 쇄토작업도중에 로타리축(1)의 회전력에 의해 너트(5)가 조금 뚫리게 되어 있어 삽입구(101)에 삽입되어 있는 삽입부(201)는 쇄기(4)가 볼트공(101')(202)에 완강히 끼여서 박혀 있기 때문에 볼트(3)가 흔들리지 않게 하여 주게 됨은 물론, 삽입부(201) 양측에 형성된 돌편(203)의 일부 역시 삽입구(101) 외단에 완전 밀착되게 꽉 끼여서 결착이 되어 있으므로 써래발(2)은 유동되지 않게 되는 것이다.When the assembly is performed in this way, the nut 5 is slightly penetrated by the rotational force of the rotary shaft 1 during the plowing work. Therefore, the inserting portion 201 inserted into the insertion hole 101 has a bolt hole 101 '. (202) is firmly stuck in the bolt (3) is not to be shaken, as well as part of the protrusion (203) formed on both sides of the insertion portion 201 is also tightly fitted tightly to the outer end of the insertion hole 101, the binding is Since the foot 2 is not flowing.

또한, 장기간 사용으로 써래발(2)이 마모되거나 파손되어 교체하고자 할때에는 너트(5)를 먼저 풀어준 다음 볼트(3)의 나선봉 단부를 공구를 사용 반대측으로 타격하여 쇄기(4)가 볼트공(101')(202)에 꽉 기여져 있는 상태만 해제시켜 주면 간단히 쇄기(4)와 볼트(3)를 분리시켜 줄 수 있게 되며, 이후 써래발(2)의 외단부를 공구를 사용 외측으로 타격하면 쉽게 분리되므로 새로운 써래발(2)을 용이하게 교체할 수 있게 되는 것이다.In addition, when the lap foot 2 is worn out or damaged due to long-term use, the nut 5 must be loosened first, and then the spiral rod end of the bolt 3 is hit with the tool to the opposite side so that the wedge 4 can be By releasing only the state that is tightly contributed to the balls 101 'and 202, the wedge 4 and the bolt 3 can be separated easily. If you hit with the easy separation will be able to easily replace the new harrow (2).

또한, 장기간 사용으로 써래발(2)이 마모되거나 파손되어 교체하고자 할때에는 너트(5)를 먼저 풀어준 다음 볼트(3)의 나선봉 단부를 공구를 사용 반대측으로 타격하여 쇄기(4)가 볼트공(101')(202)에 꽉 끼여져 있는 상태만 해제시켜 주면 간단히 쇄기(4)와 볼트(3)를 분리시켜 줄 수 있게 되며, 이후 써래발(2)의 외단부를 공구를 사용 외측으로 타격하면 쉽게 분리되므로 새로운 써래발(2)을 용이하게 교체할 수 있게 되는 것이다.In addition, when the lap foot 2 is worn out or damaged due to long-term use, the nut 5 must be loosened first, and then the spiral rod end of the bolt 3 is hit with the tool to the opposite side so that the wedge 4 can be If only the state that is tightly inserted in the ball 101 'and 202 can be released, the wedge 4 and the bolt 3 can be separated easily. If you hit with the easy separation will be able to easily replace the new harrow (2).

이와같이 사용하는 본 고안은 써래발을 유동되지 않게 완강히 결착시켜 주므로 쇄토능률이 향상되고, 수명도 연장되는 등 매우 실용적인 고안이다.The present invention used in this way is a very practical design, such as improving the loess efficiency and extending the lifespan because it firmly binds the rafters not to flow.
