Description

해로우를 갖는 경작장치Tillage device with harrow
본 발명은 해로우를 갖는 경작장치에 관한 것으로, 특히 트랙터의 견인력에 의해 경작지를 경작하는 경작장치에 설치되어 경작된 땅을 파쇄함과 동시에 고르게 평탄화하는 해로우를 갖는 경작장치에 관한 것이다.The present invention relates to a cultivation apparatus having a harrow, and more particularly, to a cultivation apparatus having a harrow installed in a cultivation apparatus for cultivating cultivated land by a traction force of a tractor to crush the cultivated land and evenly flatten the cultivated land.
본 발명에서는 경작기 중에 대표적으로 사용되는 쟁기를 예를 들어 종래의 기술과 본 발명의 기술을 설명하지만, 이는 쟁기에 한정되는 것이 아니다.In the present invention, the conventional technique and the technique of the present invention are described by way of example of a plow that is typically used among cultivators, but this is not limited to the plow.
일반적으로 쟁기는 작물을 재배할 목적으로 우마 등의 가축이나 기계 등을 이용하여 흙을 파서 일구고 뒤집어 엎어 두둑을 만드는 데 사용하는 것이다.In general, plows are used to cultivate crops by digging up the soil using livestock such as horses or machinery, etc., and turning it over to make a pile.
통상적인 트랙터용 쟁기장치는 그 예로서, 본 출원인이 등록한 실용신안 제20-0200074호(트랙터용 개량쟁기)에 나타난 바와 같이, 전방프레임과 후방프레임으로 구성된 지지체의 전방 프레임에 복수의 앞쟁기부가 구비되고, 후방프레임에는 복수의 후방프레임이 구비된 구조를 들 수 있다.As an example of a conventional plowing device for a tractor, as shown in Utility Model No. 20-0200074 (Improved Plow for Tractor) registered by the present applicant, a plurality of front plows are provided on the front frame of the support composed of the front frame and the rear frame. And a structure in which a plurality of rear frames are provided in the rear frame.
이러한 구조의 쟁기장치에 의해 경작지의 땅이 일구어지게 되고, 일구는 과정 중에 발생된 흙덩어리를 잘게 파쇄하기 위하여 해로우를 사용하게 된다.By the plowing device of this structure, the land of the cultivated land is cultivated, and the harrow is used to finely crush the mass of soil generated during the cultivation process.
등록특허 제10-1053758호(보습부가 구비된 해로우 배토기)에서는 본체의 하측부에서 일정 간격으로 회전가능하게 수직 형성된 복수개의 경운칼날이 트랙터의 구동부와 기어체결되어 동력을 인가받음으로써 수평방향으로 회전하여 흙을 잘게 파쇄하게 된다.In Registered Patent No. 10-1053758 (Harrow clay pot equipped with a moisturizing part), a plurality of cultivation blades vertically formed to be rotatable at regular intervals at the lower side of the main body are connected to the driving part of the tractor to receive power in the horizontal direction. It rotates to crush the soil finely.
그런데, 종래의 해로우는 복수의 경운칼날에 동력을 전달하기 위한 기어체결구조로 되어 있어서, 그 구조가 매우 복잡하고, 또한 그 복잡성에 의해 제조비용도 상승하는 문제점이 있다.However, since the conventional harrow has a gear fastening structure for transmitting power to a plurality of tillage blades, the structure is very complex, and there is a problem in that the manufacturing cost increases due to the complexity.
또한, 이러한 해로우는 흙덩어리를 잘게 파쇄할 수 있지만, 파쇄된 흙을 평탄화하지 못하고, 또한 흙을 일굴 때 파헤쳐지는 지푸라기, 뿌리 등의 부산물 등은 지면 위로 노출됨으로써 이를 별도로 제거하여야 하므로 작업성이 매우 좋지 않게 된다.In addition, these harrows can crush the soil finely, but the crushed soil cannot be flattened, and by-products such as straw and roots, which are dug when the soil is excavated, are exposed above the ground and thus have to be removed separately. It is not good.

그러나, 다음에 예시하는 본 발명의 실시 예는 여러 가지 다른 형태로 변형될 수 있으며, 본 발명의 범위가 다음에 상술하는 실시 예에 한정되는 것은 아니다. However, the embodiments of the present invention exemplified below may be modified in various forms, and the scope of the present invention is not limited to the embodiments described below.
본 발명의 실시 예는 당업계에서 통상의 지식을 가진 자에게 본 발명을 보다 완전하게 설명하기 위하여 제공되어지는 것이다.The embodiments of the present invention are provided to more completely describe the present invention to those of ordinary skill in the art.
본 발명의 제1실시예는 크게 프레임(100), 전방 경작부(130), 후방 경작부(140), 후방 해로우(200)로 구성된다.The first embodiment of the present invention is largely composed of a frame 100, a front cultivation unit 130, a rear cultivation unit 140, and a rear harrow 200.
여기서 전방 경작부(130) 및 후방 경작부(140)는 경작기의 한 종류인 쟁기를 일예로 하여 도시하였으며, 또한, 프레임(100)에 후방 경작부(140)만 구비된 형태를 가질 수 있다.Here, the front cultivation unit 130 and the rear cultivation unit 140 are illustrated as an example of a plow, which is a type of cultivation machine, and may have a form in which only the rear cultivation unit 140 is provided in the frame 100. .
프레임(100)은 트랙터의 후방에 연결되어 견인되는 것으로서, 그 전방의 상하방향으로 3점식의 트랙터 연결부(110,120)가 구비되어 있으며, 상기 프레임(100)의 전방부위에는 복수의 경작기가 간격을 두고 상기 프레임(100)의 폭방향으로 고정되는 전방 경작부(130)가 설치되고, 프레임(100)의 후방부위에도 마찬가지로 복수의 경작기가 간격을 두고 상기 프레임(100)의 폭방향으로 고정되는 후방 경작부(140)가 설치되어 있다.The frame 100 is connected to the rear of the tractor and is towed, and is provided with a three-point tractor connection part 110 and 120 in the vertical direction in front of the frame 100, and a plurality of tillers are spaced apart from the front part of the frame 100. A front cultivation unit 130 fixed in the width direction of the frame 100 is installed, and a plurality of cultivators are fixed in the width direction of the frame 100 at intervals similarly to the rear part of the frame 100 The unit 140 is installed.
이러한 전방 경작부(130)와 후방 경작부(140)는 어느 하나의 경작부(130 또는 140)만 프레임(100) 상에 설치되거나 또는 2개의 경작부(130,140) 모두 프레임(100)의 전후방에 각각 설치될 수 있다.These front cultivation unit 130 and rear cultivation unit 140 are installed on the frame 100 only one cultivation unit 130 or 140, or both cultivation units 130 and 140 are front and rear of the frame 100 Each can be installed.
상기 후방 경작부(140)의 후방에는 후방 해로우(200)가 구비되는데, 이러한 후방 해로우(200)는 프레임(100)에 일측이 힌지(171)에 의해 회전가능하게 축설되고, 타측은 지지프레임(210)에 힌지부(220)에 의해 회전가능하게 축설된 실린더(170)에 의해 상하방향으로 회전하여 지면으로부터 들어올려지거나 또는 지면으로 내려질 수 있도록 구성된다.A rear harrow 200 is provided at the rear of the rear cultivation unit 140, and the rear harrow 200 is rotatably built on one side of the frame 100 by a hinge 171, and the other side is a support frame ( It is configured to be lifted from the ground or lowered to the ground by rotating in the vertical direction by the cylinder 170 rotatably installed by the hinge portion 220 at 210).
또한 후방 해로우(200)가 프레임(100)에 안정적으로 지지되면서 상기 실린더(170)에 의해 상하방향으로 회전이 가능하도록 실린더(170)의 양측에는 한 쌍의 후방 지지암(150,160)이 위치하며, 그 후방 지지암(150,160))의 일측은 상기 프레임(100)에 상하방향으로 회전가능하도록 축설되고, 타측은 후방 해로우(200)에 고정된다.In addition, a pair of rear support arms 150 and 160 are positioned on both sides of the cylinder 170 so that the rear harrow 200 is stably supported by the frame 100 and can be rotated in the vertical direction by the cylinder 170, One side of the rear support arms 150 and 160 is installed to be rotatable in the vertical direction on the frame 100, and the other side is fixed to the rear harrow 200.
상기 후방 해로우(200)는 도2에 도시된 바와같이, 한 쌍의 후방 지지암(150,160)에 의해 트랙터의 견인방향으로 회전하여 구르는 흡사 통 형태로 구성되는데, 프레임(100)의 폭방향으로 길게 위치하는 지지프레임(210)이 구비되어 상기 실린더(170)의 타측이 중앙에 축설되고, 또한, 그 양측으로는 각각 후방 지지암(150,160)의 타측이 고정된다.As shown in FIG. 2, the rear harrow 200 is configured in the form of a similar cylinder that rotates and rolls in the traction direction of the tractor by a pair of rear support arms 150, 160, and is elongated in the width direction of the frame 100. The support frame 210 is provided so that the other side of the cylinder 170 is built in the center, and the other side of the rear support arms 150 and 160 is fixed to both sides thereof.
상기 지지프레임(210)의 양단은 하측으로 연장되고, 그 연장된 부위에는 각각 원판 형태의 회전판(230,240)이 각각 트랙터의 견인방향으로 회전하도록 회전축(231,241)에 의해 축설되며, 그 한 쌍의 회전판(230,240) 사이에는 복수의 연결바(250)가 위치하여 그 회전판(230,240)을 서로 연결시키게 된다.Both ends of the support frame 210 extend downward, and at the extended portions, rotary plates 230 and 240 in the form of a disk are respectively installed by rotary shafts 231 and 241 to rotate in the traction direction of the tractor, and a pair of rotary plates A plurality of connection bars 250 are positioned between the 230 and 240 to connect the rotating plates 230 and 240 to each other.
즉, 봉 형태로 된 복수의 연결바(250)의 양단이 회전판(230,240)의 둘레를 따라서 일정간격마다 고정됨으로써 지지프레임(210)의 양단에서 서로 이격된 회전판(230,240)을 서로 연결하게 되며, 트랙터의 견인에 의해 구름운동이 가능하게 된다.That is, both ends of the plurality of connecting bars 250 in the form of rods are fixed at regular intervals along the circumference of the rotating plates 230 and 240 to connect the rotating plates 230 and 240 spaced apart from each other at both ends of the support frame 210, Rolling motion is possible by traction of the tractor.
이때, 상기 복수의 연결바(250)들은 그 양단이 회전판(230,240)의 동일한 위치에 수평하게 고정되지 않고, 일측방향에서 타측방향으로 갈수록 약간 하향경사지도록 연결되는 것이 바람직하다.At this time, it is preferable that both ends of the plurality of connection bars 250 are not fixed horizontally at the same position of the rotating plates 230 and 240, but are connected such that they are slightly inclined downward from one direction to the other.
이는 전방 및 후방 경작부(130,140)에 의해 경작된 흙덩어리를 효율적으로 파쇄화면서 또한 지푸라기, 뿌리 등의 부산물을 지면 속으로 효과적으로 매몰시킬 수 있도록 하기 위함이다.This is to effectively crush the soil mass cultivated by the front and rear cultivation units 130 and 140 and to effectively bury by-products such as straw and roots into the ground.
즉, 하나의 연결바(250)가 일측으로부터 타측으로 지면에 시간을 두고 연속하여 접촉함으로써 흙덩어리 또는 부산물의 저항을 최소화하면서 파쇄 작업을 할 수 있도록 하는 것이다.That is, one connecting bar 250 is in continuous contact with the ground from one side to the other for a period of time so that the crushing operation can be performed while minimizing the resistance of a mass of soil or by-product.
또한, 상기 연결바(250)들은 긴 봉 형태로 되어 있으므로, 흙덩어리 또는 뿌리 등의 저항에 의해 휘어질 수 있으므로, 그 연결바(250)들의 간격을 안정적으로 유지하면서 또한 휘어짐을 방지하기 위하여 복수의 지지부(260)가 일정간격마다 구비되어 있다.In addition, since the connection bars 250 are in the form of long rods, they may be bent by resistance such as a mass of soil or roots, so that a plurality of connection bars 250 are maintained in order to stably maintain the distance between the connection bars 250 and prevent bending. The supporting parts 260 are provided at regular intervals.
이러한 지지부(260)는 원형의 링 형태로서 상기 복수의 연결바(250)들의 내측으로 삽입되어 그 외측으로 연결바(250)들이 고정되거나 또는 지지부(260)의 내측으로 상기 연결바(250)들을 삽입시켜 그 내측으로 연결바(250)들을 고정시킬 수 있다.The support part 260 is a circular ring shape and is inserted into the inner side of the plurality of connection bars 250 so that the connection bars 250 are fixed to the outside thereof, or the connection bars 250 are inserted inside the support part 260. By inserting, the connection bars 250 may be fixed to the inside thereof.
도면에서는 링 형태의 지지부(260)가 연결바(250)들의 내측으로 삽입되어 그 외측으로 복수의 연결바(250)들이 고정되는 구조를 도시하였으나, 이는 원판의 형태를 가질 수 있으며, 연결바(250)들의 외측의 끼워지는 경우에는 링의 형태를 가지게 된다.In the drawing, a structure in which a ring-shaped support part 260 is inserted into the inner side of the connecting bars 250 and a plurality of connecting bars 250 are fixed to the outer side thereof is shown, but this may have a form of a disc, and the connecting bar ( 250) will have the shape of a ring when they are fitted outside.
상기 지지부(260)는 도3에 도시한 바와같이 원형의 링 형태로 되고, 외측으로는 상기 연결바(250)들이 접촉하여 고정될 부위에 연결바(250)를 끼워서 고정하기 위한 연결바 끼움홈(261)이 일정간격마다 형성되어 있어서, 연결바(250)를 연결바 끼움홈(261)에 삽입시킨 다음 용접 등에 의해 고정시키게 된다.The support part 260 has a circular ring shape as shown in FIG. 3, and a connection bar fitting groove for inserting and fixing the connection bar 250 to a portion to be fixed by contacting the connection bars 250 to the outside. Since 261 is formed at regular intervals, the connecting bar 250 is inserted into the connecting bar fitting groove 261 and then fixed by welding or the like.
물론, 이러한 지지부(260)는 상기에서 언급한 바와 같이 원판의 형태를 가질 수 있다.Of course, the support part 260 may have the shape of a disk as mentioned above.
또한, 상기 지지부(260)에는 일정간격마다 파쇄날(270)이 고정되어 있는데, 상기 파쇄날(270)은 연결바 끼움홈(261) 사이에서 탈부착이 가능하도록 고정되어 설치되며, 지지부(260)의 외측방향으로 돌출되도록 설치된다.In addition, a crushing blade 270 is fixed to the support 260 at regular intervals, the crushing blade 270 is fixed and installed between the connecting bar fitting grooves 261 so as to be detachable, and the support 260 It is installed to protrude in the outward direction of
이는 연결바(250)와 간섭되지 않는 위치 즉, 연결바(250)들 사이의 간격을 통해 외측으로 돌출되도록 고정되어 경작부(130,140)에 의해 일궈진 흙덩어리를 잘게 파쇄하게 된다.This is fixed so as to protrude outward through the gap between the connection bars 250, that is, a position that does not interfere with the connection bar 250, and finely crush the soil mass raised by the cultivation parts 130 and 140.
즉, 연결바(250)의 회전에 의해서도 흙덩어리가 파쇄될 수 있지만, 파쇄날(270)에 의해 흙덩어리를 더욱 잘게 파쇄함으로써 평탄화 작업이 더욱 효율적으로 행해질 수 있도록 하는 것이다.That is, although the soil mass may be crushed by the rotation of the connection bar 250, the soil mass is crushed more finely by the crushing blade 270 so that the planarization work can be performed more efficiently.
상기 파쇄날(270)의 탈부착을 위하여 연결바 끼움홈(261)의 사이마다 고정공(262)이 형성되고, 상기 파쇄날(270)의 하부에는 볼트공(271)이 형성되어 있어서, 볼트공(271)과 고정공(262)을 관통하여 볼트(272)가 삽입되고, 너트(273)에 의해 체결되는 구조를 가질 수 있다.A fixing hole 262 is formed between the connecting bar fitting grooves 261 for attaching and detaching the crushing blade 270, and a bolt hole 271 is formed in the lower portion of the crushing blade 270, The bolt 272 is inserted through the 271 and the fixing hole 262, and may have a structure that is fastened by a nut 273.
물론, 이러한 파쇄날(270)의 탈부착 구조는 다양하게 실현될 수 있으며, 아울러 파쇄날(270)의 구조도 흙덩어리를 파쇄하기 다양한 형태를 가질 수 있을 것이다. Of course, the detachable structure of the crushing blade 270 may be realized in various ways, and the structure of the crushing blade 270 may also have various shapes for crushing a mass of soil.
본 발명의 제1실시예에 따른 동작상태를 설명한다.The operation state according to the first embodiment of the present invention will be described.
이동중에는 실린더(170)가 압축됨으로써 후방 해로우(200)가 들려진 상태로 이동이 가능하며, 경작 작업을 위한 현장에서는 실린더(170)를 신장시켜 후방 해로우(200)가 지면에 접촉하도록 내리게 된다.During movement, the cylinder 170 is compressed so that the rear harrow 200 can be moved in a lifted state, and in the field for cultivation, the cylinder 170 is extended and the rear harrow 200 is lowered to contact the ground.
이때, 후방 해로우(200)가 지면에 접촉한 상태에서 실린더(170)가 더 신장하게 되면, 상기 후방 해로우(200)가 지면에 지지되면서 프레임(100)의 후방이 들어올려지게 되므로, 전방 경작부(130)와 후방 경작부(140)도 들어올려지게 되어 경작 깊이 즉 경심이 얕아지게 된다.At this time, when the cylinder 170 is further elongated while the rear harrow 200 is in contact with the ground, the rear harrow 200 is supported on the ground and the rear of the frame 100 is lifted. 130 and the rear cultivation unit 140 are also lifted so that the cultivation depth, that is, the cultivation depth is shallow.
반대로, 후방 해로우(200)가 지면에 근접한 상태가 되도록 실린더(170)가 신장하게 되면, 후방 해로우(200)가 지면에 지지되지 않은 상태에서 프레임(100)과 전방 경작부(130), 그리고 후방 경작부(140)의 자중에 의해 땅을 깊게 파고들게 되어 경심이 깊어지게 되는 것이다.On the contrary, when the cylinder 170 is elongated so that the rear harrow 200 is close to the ground, the frame 100 and the front cultivation unit 130 and the rear harrow 200 are not supported on the ground. By the self-weight of the cultivation unit 140, the ground is dug deeper, and the mind is deepened.
물론, 전방 경작부(130)와 후방 경작부(140)가 땅을 파고 들게 되어 프레임(100)이 하강하게 되면, 다시 후방 해로우(200)는 실린더(170)의 신장없이도 자연스럽게 지면에 접촉되어 지지되므로, 그 지지력에 의해 그 위치에서 경심이 고정되는 것이다.Of course, when the front cultivation unit 130 and the rear cultivation unit 140 dig into the ground and the frame 100 is lowered, the rear harrow 200 is naturally in contact with the ground without the extension of the cylinder 170 and is supported. Therefore, the core is fixed at that position by the support force.
결국, 실린더(170)의 신장되는 길이에 따라 후방 해로우(200)의 높낮이를 조절함으로써 전방 경작부(130)와 후방 경작부(140)의 경심을 조절할 수 있는 것이다.As a result, by adjusting the height of the rear harrow 200 according to the elongated length of the cylinder 170, it is possible to adjust the depths of the front cultivation unit 130 and the rear cultivation unit 140.
이후, 트랙터가 전진하여 프레임(100)을 견인하게 되면, 전방 경작부(130)와 후방 경작부(140)가 설정된 경심에 따라 지면을 파고 들면서 땅을 일구게 되고, 후방 해로우(200)는 그 견인력에 의해 견인방향으로 구름운동을 하면서 상기 경작부(130,140)에 의해 일궈진 흙덩어리를 연결바(250)와 파쇄날(270)이 잘게 파쇄하면서 평탄화 작업을 하게 된다.Thereafter, when the tractor advances and pulls the frame 100, the front cultivation unit 130 and the rear cultivation unit 140 dig the ground according to the set cultivation center and dig the ground, and the rear harrow 200 is While rolling in the traction direction by the traction force, the connecting bar 250 and the crushing blade 270 finely crush the soil mass raised by the cultivation units 130 and 140 to perform a planarization operation.
또한, 연결바(250)의 회전에 의해 지푸라기, 뿌리 등의 부산물을 지면으로 파 묻게 된다.In addition, by-products such as straw and roots are dug into the ground by the rotation of the connecting bar 250.
따라서, 연결바(250)의 회전에 의해 정지(整地) 작업이 매우 수월하게 이루어지는 것이다.Therefore, the stop (整地) work is made very easily by the rotation of the connection bar (250).
본 발명의 제2실시예는 전방 경작부(130)와 후방 경작부(140) 사이에 전방 해로우(300)를 구비한 것으로서, 전방 해로우(300)의 구조는 본 발명의 제1실시예의 후방 해로우(200)의 구조와 동일하다.The second embodiment of the present invention is provided with a front harrow 300 between the front cultivation unit 130 and the rear cultivation unit 140, the structure of the front harrow 300 is the rear harrow of the first embodiment of the present invention. It is the same as the structure of (200).
다만, 전방 해로우(300)가 프레임(100)에 경심 조절부(310,310')를 매개로 하여 지지되는 구조가 다른데, 상기 경심 조절부(310,310')에 의해 전방 해로우(300)의 높이가 조절됨으로써 전방 경작부(130)와 후방 경작부(140)의 경심이 조절될 수 있다.However, there is a different structure in which the front harrow 300 is supported by the frame 100 through the optical center adjustment units 310 and 310 ′, and the height of the front harrow 300 is adjusted by the optical center adjustment units 310 and 310 ′. The depths of the front cultivation unit 130 and the rear cultivation unit 140 may be adjusted.
즉, 트랙터와 연결되는 3점식의 트랙터 연결부(110,120)를 축으로 하여 프레임(100)의 후방이 상하방향으로 회전함으로써 전방 경작부(130)와 후방 경작부(140)의 경심을 조절하게 되지만, 후방 경작부(140)의 경심을 조절하는 경우에는 전방 경작부(130)의 경심이 후방 경작부(140)의 경심보다 얕게 설정되므로, 전방 경작부(130)를 원하는 경심으로 조절하기가 불가능하다.That is, the rear of the frame 100 is rotated in the vertical direction with the three-point tractor connection parts 110 and 120 connected to the tractor as an axis, thereby adjusting the depth of the front cultivation unit 130 and the rear cultivation unit 140, In the case of adjusting the meridian of the rear cultivation unit 140, since the meridian of the front cultivation unit 130 is set to be shallower than the meridian of the rear cultivation unit 140, it is impossible to adjust the front cultivation unit 130 to a desired meridian. .
따라서, 전방 해로우(300)의 높낮이를 조절함으로써 프레임(100) 전방의 높이를 조절하여 전방 경작부(130)의 경심을 조절하도록 한다.Accordingly, by adjusting the height of the front harrow 300, the height of the front of the frame 100 is adjusted to adjust the depth of the front cultivation unit 130.
이를 위하여 전방 해로우(300)는 경심 조절부(310,310')를 매개로 하여 프레임(100)의 전방 부위에 고정되는데, 프레임(100)의 전방부위 양측부위에서 외측방향으로 더 연장된 연장 프레임(101,101')이 구비되는데, 이러한 연장 프레임(101,101')은 전방 경작부(130)보다 더 외측으로 돌출되어 형성된다.To this end, the front harrow 300 is fixed to the front portion of the frame 100 through the optical center adjustment portions 310 and 310', and the extension frames 101 and 101 further extended outward from both sides of the front portion of the frame 100 ') is provided, and these extension frames 101 and 101' are formed to protrude further outward than the front cultivation part 130.
상기 연장 프레임(101,101')에는 각각 경심조절부(310,310')가 설치되는데, 상기 경심 조절부(310,310')는 양측이 동일한 형태를 가지므로, 하나의 경심 조절부(310)를 중심으로 구조를 설명한다.Each of the extension frames 101 and 101 ′ is provided with an optical center adjustment unit 310 and 310 ′, and since both sides of the optical center adjustment unit 310 and 310 ′ have the same shape, the structure is formed around one optical center control unit 310. Explain.
상기 경심 조절부(310)는 연장 프레임(101) 상에서 후방으로 나란히 한 쌍의 지지편(311,312)이 서로 간격을 두고 고정되며, 상기 지지편(311,312)에는 동일한 위치에서 복수의 핀공(313,314)이 형성되어 있다.In the optical center adjustment unit 310, a pair of support pieces 311 and 312 are fixed at an interval from each other on the extension frame 101, and a plurality of pin holes 313 and 314 are provided at the same position on the support pieces 311 and 312. Is formed.
이러한 핀공(313,314)은 상하방향으로 형성되어 있으며, 바람직하게는 전방 지지암(320)의 회전 경로를 따르도록 형성되는 것이 좋다.These pin holes 313 and 314 are formed in the vertical direction, and are preferably formed to follow the rotation path of the front support arm 320.
상기 전방 지지암(320)은 그 후방이 전방 해로우(300)를 향하도록 하향 경사지게 절곡되며, 그 전방은 상기 한 쌍의 지지편(311,312) 사이에서 축설부(315)에 의해 상하방향으로 회전하도록 축설되어 있다.The front support arm 320 is bent downwardly obliquely so that its rear faces the front harrow 300, and its front is rotated in the vertical direction by the shaft 315 between the pair of support pieces 311 and 312. It is built.
또한, 상기 전방 지지암(320)의 상측과 하측방향의 회전을 고정시키도록 고정핀(316,317)이 핀공(313,314)에 삽입되는데, 2개의 고정핀(316,317)이 전방 지지암(320)의 상측과 하측에서 각각 핀공(313,314)에 삽입됨으로써 전방 지지암(320)이 고정핀(316,317)에 걸리게 되어 회전하지 않도록 고정된다.In addition, the fixing pins 316 and 317 are inserted into the pin holes 313 and 314 to fix the rotation of the front support arm 320 in the upper and lower directions, and two fixing pins 316 and 317 are placed on the upper side of the front support arm 320. By being inserted into the pin holes 313 and 314, respectively, from the upper and lower sides, the front support arm 320 is caught by the fixing pins 316 and 317 and is fixed so as not to rotate.
즉, 상기의 고정핀(316,317)은 전방 지지암(320)의 회전을 방지하는 스토퍼의 역할을 하는 것이다.That is, the fixing pins 316 and 317 serve as a stopper preventing rotation of the front support arm 320.
이러한 핀공(313,314)은 전방 지지암(320)의 최대 회전각도 범위에서 복수개가 형성되며, 가장 상측에 형성된 핀공(313,314)의 하단부위는 전방 지지암(320)이 상측으로 최대 회전하였을 때 전방 지지암(320)의 상단부위와 동일한 높이가 되고, 가장 하측에 형성된 핀공(313,314)의 상단부위도 마찬가지로 전방 지지암(320)이 하측으로 최대 회전하였을 때 전방 지지암(320)의 하단부위와 동일한 높이가 되어야 한다.A plurality of these pinholes 313 and 314 are formed in the maximum rotation angle range of the front support arm 320, and the lower portion of the pinholes 313 and 314 formed at the uppermost side is front support when the front support arm 320 is rotated upwardly It is the same height as the upper part of the arm 320, and the upper part of the pinholes 313 and 314 formed at the lowermost side is also the same height as the lower part of the front support arm 320 when the front support arm 320 rotates to the lower side. Should be.
또한, 각 핀공(313,314)의 간격은 전방 지지암(320)의 두께만큼을 가지게 된다.In addition, the interval between each pin hole (313, 314) is to have the thickness of the front support arm (320).
상기 전방 지지암(320)에는 전방 해로우(300)의 양측이 회전축(321)에 의해 축설되어 회전하도록 결합된다. Both sides of the front harrow 300 are installed on the front support arm 320 by a rotation shaft 321 and coupled to rotate.
따라서, 도4에서와 같이 전방 지지암(320)을 핀공(313,314)과 고정핀(316,317)에 의해 경사각도를 조절하여 고정시키게 되면, 지면(G)에 전방 해로우(300)가 접지되어 버티게 됨으로써 그 접지되는 힘에 의해 프레임(100)의 들리는 정도가 조절되어 결국, 전방 경작기(130)가 땅을 파고드는 깊이 즉 경심이 조절되는 것이다.Therefore, when the front support arm 320 is fixed by adjusting the inclination angle by the pin holes 313 and 314 and the fixing pins 316 and 317 as in FIG. 4, the front harrow 300 is grounded to the ground G to hold it. The degree of lifting of the frame 100 is adjusted by the grounding force, and as a result, the depth at which the front tiller 130 digs into the ground, that is, the center of gravity is adjusted.
즉, 경심을 얕게 하고자 한다면 전방 지지암(320)의 경사각도를 크게 하여 전방 해로우(300)가 프레임(100)을 밀어서 들어올림으로써 프레임(100)과 지면(G)의 이격거리를 크게 하여 전방 경작기(130)의 경심을 얕게 조절하고, 반대로 경심을 깊게 하고자 한다면, 전방 지지암(320)의 각도를 완만하게 하여 프레임(100)과 지면(G)의 이격거리를 작게함으로써 전방 경작기(130)가 땅을 깊게 파고들 수 있도록 조절하게 된다.That is, if you want to make the center of gravity shallow, the inclination angle of the front support arm 320 is increased, and the front harrow 300 pushes and lifts the frame 100, thereby increasing the distance between the frame 100 and the ground (G). If the cultivation center of the cultivation machine 130 is adjusted to be shallow, and on the contrary, if the cultivation center is to be deepened, the angle of the front support arm 320 is made gentle to reduce the separation distance between the frame 100 and the ground G. 130) to dig deeper into the ground.
이러한 경심 조절부(310)의 또다른 형태로서, 전방 지지암(320)을 관통하여 핀공이 형성되어 하나의 고정핀이 핀공(313,314)과 전방 지지암(320)에 형성된 핀공을 관통하여 체결됨으로써 전방 지지암(320)의 회전을 고정시키는 구조를 가질 수 있다.As another form of such an optical center adjusting part 310, a pin hole is formed through the front support arm 320, so that one fixing pin penetrates through the pin holes 313 and 314 and the pin hole formed in the front support arm 320 and is fastened. It may have a structure to fix the rotation of the front support arm (320).
아울러, 전방 해로우(300)는 전방 경작부(130)와 후방 경작부(140) 사이에 위치함으로써 전방 경작부(130)에 의해 일궈진 흙을 파쇄하여 후방으로 넘기게 되는데, 전방 해로우(300)가 구비되지 않고 전방 경작부(130)와 후방 경작부(140)만 구비된 경작기의 경우에는 전방 경작부(130)로부터 일궈진 흙덩어리가 후방 경작부(140)에 걸려서 후방으로 원할히 배출되지 못함으로써 흙덩어리가 적체되는 현상이 발생한다.In addition, the front harrow 300 is located between the front cultivation unit 130 and the rear cultivation unit 140 to crush the soil raised by the front cultivation unit 130 and pass it to the rear, the front harrow 300 In the case of a cultivator that is not provided with only the front cultivation unit 130 and the rear cultivation unit 140, the mass of soil raised from the front cultivation unit 130 is caught by the rear cultivation unit 140 and is not discharged smoothly to the rear. As a result, the soil mass accumulates.
특히 진흙과 같은 경작지에서는 이러한 흙덩어리에 의해 전방 경작부(130)와 후방 경작부(140) 사이에 많은 적체 현상이 발생하여 작업이 수월하지 않게 된다.In particular, in cultivated land such as mud, a lot of congestion occurs between the front cultivation unit 130 and the rear cultivation unit 140 due to such a mass of soil, so that the work is not easy.
따라서, 본 발명의 전방 해로우(300)는 전방 경작부(130)로부터 일궈진 흙덩어리를 잘게 부수게 됨으로써 후방 경작부(140)의 사이를 통해 쉽게 후방으로 배출될 수 있어서 흙덩어리의 적체 현상이 해소되는 것이다.Accordingly, the front harrow 300 of the present invention can be easily discharged to the rear through the rear cultivation unit 140 by breaking the soil mass raised from the front cultivation unit 130, so that the accumulation of the soil lump is reduced. It is resolved.
한편, 진흙 형태의 경작지를 경작하는 경우에는 후방 경작부(140)가 땅을 일굴 때 경작하고자 하는 부위의 측면부위 외측의 흙까지 덩어리 형태로 일궈지므로 경작지의 가장자리 면이 매우 지저분하게 일궈지게 된다.On the other hand, in the case of cultivating the cultivated land in the form of mud, when the rear cultivation unit 140 digs the ground, the soil outside the side of the cultivated part is raised in a lump form, so that the edge of the cultivated land is raised very messy.
그러므로, 전방 해로우(300)가 견인될 때 회전판(322)이 경작지를 파고들면서 땅을 직선으로 절개함으로써 뒤따르는 후방 경작부(140)가 그 절개된 범위 내에서만 땅을 일구도록 하여 경작지의 가장자리를 깨끗하게 할 수 있다.Therefore, when the front harrow 300 is towed, the rotating plate 322 penetrates the arable land and cuts the ground in a straight line, so that the rear cultivation unit 140 that follows it to cultivate the ground only within the cut-off range, thereby making the edge of the arable land. You can clean it.
이를 위해 도5에 도시한 바와같이 전방 해로우(300)의 회전판(322)의 외주면과 연결바(350)와의 간격을 경작지의 절개 깊이에 대응하는 간격(D)를 갖도록 함으로써 회전판(322)이 회전하면서 경작지를 절개하게 되는 것이다.To this end, as shown in Fig. 5, the rotation plate 322 rotates by making the distance between the outer circumferential surface of the rotation plate 322 of the front harrow 300 and the connection bar 350 have a distance D corresponding to the cutting depth of the arable land. In doing so, they cut the cultivated land.
본 발명의 제3실시예로서, 전방 경작부(130)와 후방 경작부(140) 사이에 전방 해로우(300)를 구비하고, 후방 경작부(140)의 후방에 후방 해로우(200)를 구비한 구조를 가질 수 있다.As a third embodiment of the present invention, a front harrow 300 is provided between the front cultivation unit 130 and the rear cultivation unit 140, and the rear harrow 200 is provided at the rear of the rear cultivation unit 140. It can have a structure.
이러한 전방 해로우(300)와 후방 해로우(200)의 구조는 상기에서 설명한 구조와 동일하다.The structures of the front harrow 300 and the rear harrow 200 are the same as those described above.
따라서, 전방 해로우(300)가 전방 경작부(130)에 의해 일궈진 흙덩어리를 1차로 파쇄하여 적체 현상을 해소하고, 후방 해로우(200)가 2차로 흙을 잘게 파쇄하면서 평탄화 작업까지 하게 된다.Therefore, the front harrow 300 first crushes the soil mass raised by the front cultivation unit 130 to eliminate the congestion phenomenon, and the rear harrow 200 secondarily crushes the soil finely and even flattening the soil.
한편, 도6에 도시한 바와 같이 전방 해로우(300)와 후방 해로우(200) 사이를 체인(400) 또는 벨트에 의해 연결하여 서로 회전력을 전달하는 구조를 가질 수 있는데, 상기 전방 해로우(300)의 회전축(321)과 후방 해로우(200)의 회전축(231)에는 각각 스프로켓(370) 또는 풀리가 결합되고, 스프로켓(370) 또는 풀리를 체인(400) 또는 벨트가 연결함으로써 회전력 즉 구동력을 서로 전달하게 된다.Meanwhile, as shown in FIG. 6, the front harrow 300 and the rear harrow 200 may be connected by a chain 400 or a belt to transmit rotational force to each other. A sprocket 370 or a pulley is coupled to the rotation shaft 321 of the rotation shaft 321 and the rear harrow 200, respectively, and a chain 400 or a belt connects the sprocket 370 or pulley to transmit rotational force, that is, driving force to each other. do.
즉, 정애물에 의해 어느 하나의 해로우가 회전력이 저하되면, 다른 하나의 해로우가 회전력을 전달하여 보충함으로써 원할한 파쇄작업 및 견인이 가능하도록 하는 것이다.That is, when the rotational force of one of the harrows is lowered by the crushed material, the other harrow transmits and supplements the rotational force, thereby enabling smooth crushing and traction.
