본 발명은 버켓 각도 조절을 위한 로우더 구조에 관한 것으로, 특히 붐대의 위치 조절시 회전판이 회전하면서 보강부재가 함께 위치조정이 붐대와 함께 이루어져 보강부재의 변형을 방지하는 버켓 각도 조절을 위한 로우더 구조에 관한 것이다.The present invention relates to a loader structure for adjusting the angle of a bucket. More particularly, the present invention relates to a loader structure for adjusting a bucket angle, in which a rotary plate is rotated to adjust a position of a bucket, .

일반적으로 농업, 축산, 어업 등 여러 분야에서는 트랙터, 굴삭기와 같은 농기계에 사용목적에 따라 다양한 종류의 작업기를 선택적으로 연결하여 작업을 하였다.Generally, in various fields such as agriculture, animal husbandry and fishery, various kinds of working machines are selectively connected to agricultural machinery such as tractor and excavator according to the purpose of use.

이러한, 트랙터는 다양한 작업이 가능하도록 제작되어 있으며 그중에도 트랙터의 전방에 장착하여 다양한 작업에 응용되는 장치가 프론트 로우더이다. 프론트 로우더는 국내에 몇가지 형식의 제품이 보급되고 있으며 그 기술력도 높은 수준을 보이고 있다. 프론트 로우더의 다기능 작업 능력은 다양한 작업 환경이 주어진 우리의 농업 현실에 잘 부합되고 있으며, 농사의 힘든 노동을 담당하여 중요한 생산 설비로서 자리잡고 있다. 프론트 로우더가 담당하는 작업 예를 보면 퇴비, 농자재, 비료등의 상차, 축사의 축분 제거작업, 가축사료의 운반, 객토작업시 땅고르기 등 이다.Such a tractor is designed to be able to perform various operations, and the front loader is a device that is applied to various jobs by being mounted in front of a tractor. The front loader has several types of products in Korea, and its technology is also high. The multifunctional working ability of the front loader is matched to our agricultural realities given various working environments and it is positioned as an important production facility in charge of hard labor of farming. Examples of operations that the front loader is responsible for include: composting, farming materials, fertilizer and other carpentry, removing animal fodder, transportation of livestock feed, and land selection.

종래의 트랙터용 로우더는 좌우 브라케트에 핀과 붐 실린더로 각각 조립된 좌우 붐과; 좌우 붐의 외단에 핀과 링크와 작업기 실린더로 조립된 프레임과; 프레임에 장착되는 작업기 커플러와; 작업기으로 구성되어있고, 브라케트로 붐을 트렉터에 장착하고, 트랙터에서 취출되는 유압을 제어밸브를 통해 실린더에 공급하여 붐과 작업기을 구동하도록 하는 것이었다. 이와 같은 로우더는 트랙터에 한번 장착되면 화물의 상하차, 운반 및 땅고르기 등에 여러 직업에 두루 사용되므로 트랙터에 장착한 상태에서 트랙터를 타 용도에 사용하는 경우가 일반적이다.The conventional tractor loader includes left and right boom assembled with pins and boom cylinders in left and right brackets; A frame assembled with pins and links and a working machine cylinder at the outer ends of the left and right booms; A work machine coupler mounted on the frame; And the boom was mounted on the tractor with the bracket, and the hydraulic pressure taken out from the tractor was supplied to the cylinder through the control valve to drive the boom and the working machine. Such a loader is used for various occupations such as loading and unloading of cargo, transportation and land selection once mounted on a tractor, so it is common to use the tractor for other purposes while mounted on a tractor.

그러나 상기와 같은 종래의 붐을 위치를 조정할 때 보강부재가 트랙터와 결합되는 브라켓트와 작업기를 작동시키기 위한 작업기 실린더가 결합된 부분에 회전되게 설치되는데, 이때 붐 실린더의 작동으로 붐의 상하부로 회전이동시키며 작업기의 위치를 조정할 때 보강부재에 상하로 회전 이동시 발생하는 작용력과 작업기의 위치를 고정시킨 상태로 작업시 작업기에 전달되는 작용력이 보강부재로 전달되어 휨 변형이 발생되는 문제점이 있었다.However, when adjusting the position of the conventional boom as described above, the reinforcing member is rotatably installed at a portion where the bracket coupled with the tractor and the working machine cylinder for operating the work machine are rotated. At this time, The force acting on the reinforcing member in the up and down direction and the position of the working machine are fixed when the position of the working machine is adjusted, and the force transmitted to the working machine during the work is transmitted to the reinforcing member.

그리고, 상기 아암(20)의 전면으로 작업기(30)가 붐대(10)에 설치되는 제1작동기(11) 및 아암(20)에 설치되는 제2작동기(21)에 의해 상하 각도 조절이 가능하도록 구성된다.The upper and lower angles can be adjusted by the first actuator 11 installed on the boom frame 10 and the second actuator 21 installed on the arm 20 on the front surface of the arm 20 .

아울러, 상기 붐대(10)의 내부로 삽입되어 장치브라켓(12)과 붐대(10)와 아암(20)이 연결되는 링크연결부(13)의 내부에 회전되게 결합되는 회전판(40)의 하부에 보강부재(50)를 회전하게 연결 구성한다.The lower part of the rotary plate 40 which is inserted into the boom frame 10 and is rotatably coupled to the inside of the link bracket 13 to which the apparatus bracket 12 and the boom frame 10 and the arm 20 are connected is reinforced And the member 50 is connected to rotate.

이러한, 상기 보강부재(50)는 중앙 하부면이 내측으로 곡률지게 함몰된 곡률면(51)을 형성하여 휨 응력에 대하여 대응력 및 응력 분산력이 상승하도록 구성한다.The reinforcing member 50 has a central lower surface formed with a curved surface 51 curved downward inward, so that the corresponding force and the stress dispersive force are increased with respect to the bending stress.

이때, 상기 붐대(10)의 일 끝단에는 트랙터와 같은 장치에 연결되기 위한 장치브라켓(12)이 힌지핀(P)을 이용하여 결합되어 회전되게 구성된다.At this time, a device bracket 12 to be connected to a device such as a tractor is coupled to one end of the boom frame 10 using a hinge pin P and rotated.

그리고, 상기 장치브라켓(12)의 하부에는 붐대(10)의 위치를 조정하는 제1작동기(11)의 제1실린더로드(11b)가 힌지핀(P)을 이용하여 결합되어 회전되게 구성된다.The first cylinder rod 11b of the first actuator 11 for adjusting the position of the boom frame 10 is coupled to the lower portion of the apparatus bracket 12 by using a hinge pin P and rotated.

아울러, 상기 제1작동기(11)의 제1실린더(11a)는 붐대(10)의 전방 하부에 힌지핀(P)을 이용하여 결합되어 회전되게 구성된다.The first cylinder 11a of the first actuator 11 is coupled to the front lower portion of the boom frame 10 using a hinge pin P.

더불어, 상기 보강부재(50)의 일 끝단은 붐대(10)와 제1작동기(11)가 결합된 사이에 장치브라켓(12)의 중앙에 힌지핀(P)을 이용하여 결합되어 회전되게 구성된다.One end of the reinforcing member 50 is coupled to the center of the apparatus bracket 12 by being coupled with the hinge pin P between the boom frame 10 and the first actuator 11, .

한편, 상기 제2작동기(21)는 회전판(40)의 상부와 작업기(30) 및 아암(20)에 회전되게 연결되는 연결브라켓(31)에 회전되게 연결 구성한다.The second actuator 21 is rotatably connected to an upper portion of the rotary plate 40 and a connection bracket 31 rotatably connected to the working machine 30 and the arm 20.

즉, 상기 제2작동기(21)의 제2실린더(21a)는 회전판(40)과 힌지핀(P)을 이용하여 결합되어 회전되게 연결되고, 제2작동기(21)의 제2실린더로드(21b)는 연결브라켓(31)에 힌지핀(P)을 이용하여 결합되어 회전되게 구성된다.That is, the second cylinder 21a of the second actuator 21 is connected to the rotary plate 40 by using the hinge pin P to be rotated, and the second cylinder rod 21b of the second actuator 21 Is connected to the connection bracket 31 by using a hinge pin P and is rotated.

그리고, 상기 연결브라켓(31)은 한 쌍의 아암(20)의 전방측에 각각 힌지핀(P)을 이용하여 결합되어 회전되게 연결 구성된다.The connection brackets 31 are connected to the front sides of the pair of arms 20 by using hinge pins P and connected to rotate.

한편, 상기 작업기(30)는 아암(20)의 전방 끝단에 회전되게 결합되는 작업기브라켓(32)과 회전되게 결합된다.The working machine 30 is rotatably coupled to a working machine bracket 32 which is rotatably coupled to the front end of the arm 20.

더불어, 상기 회전판(40)은 반달형태로써 상,하부 끝단측은 제1,2삽입절개홈(41)(42)이 각각 형성되어 제1삽입절개홈(41)에는 제2작동기(21)의 제2실린더(21a)가 삽입되어 회전되게 결합 구성한다.The first and second insertion cut grooves 41 and 42 are formed on the upper and lower end sides of the rotary plate 40 so that the first insertion cut groove 41 is formed with the second actuator 21 2 cylinders 21a are inserted and rotated.

이러한, 상기 제2삽입절개홈(42)에는 보강부재(50)의 일 끝단이 삽입되어 회전되게 결합 구성한다.One end of the reinforcing member 50 is inserted into the second insertion incision groove 42 so as to be rotated.

아울러, 상기 회전판(40)의 중앙은 붐대(10)와 아암(20)이 겹쳐지는 링크연결부(13)와 회전되게 결합되도록 구성한다.In addition, the center of the rotary plate 40 is rotatably coupled to the link connecting portion 13 where the boom frame 10 and the arm 20 are overlapped.

즉, 상기 제1작동기(11)의 작동으로 붐대(10)의 위치를 조정할 경우 회전판(40)이 회전하면서 보강부재(50)의 휨을 방지하도록 로우더(100)를 구성하는 것이다.That is, when the position of the boom frame 10 is adjusted by the operation of the first actuator 11, the loader 100 is configured to prevent the bending of the reinforcing member 50 by rotating the rotary plate 40.

상기와 같이 구성된 본 발명의 작용 및 효과를 설명하면 다음과 같다.The operation and effect of the present invention constructed as described above will be described below.

도 5 및 도 6에 도시된 바와 같이, 상기 로우더(100)의 장치브라켓(12)을 트랙터의 전면에 결합하여 제1작동기(11)를 이용해서는 로우더(100)를 전체를 상,하부로 들어올리거나 내려지도록 회전시키는 동작을 수행하게 되며, 제2작동기(21)를 이용해서는 작업기(30)를 상하로 회전시키는 동작을 수행하게 된다.5 and 6, the apparatus bracket 12 of the loader 100 is coupled to the front surface of the tractor so that the first actuator 11 can be used to move the loader 100 upward and downward And the second actuator 21 is used to perform the operation of rotating the working machine 30 up and down.

이때, 상기 붐대(10)의 위치를 조정하기 위하여 제1작동기(11)의 제1실린더로드(11b)를 인출/삽입 작동시키면 붐대(10)가 장치브라켓(12)에서 연결된 상태로 올려지거나 내려지게 회전된다.In this case, when the first cylinder rod 11b of the first actuator 11 is pulled out / inserted to adjust the position of the boom frame 10, the boom frame 10 is raised or lowered in the state of being connected to the apparatus bracket 12 .

이때, 상기 보강부재(50)도 붐대(10)와 함께 장치브라켓(12)에서 연결된 상태로 올려지거나 내려지게 되는데, 붐대(10)가 상부로 회전하면 보강부재(50)와 연결된 회전판(40)의 하부가 작업기(30)가 위치된 전방 방향으로 회전하고, 회전판(40)의 상부는 트랙터가 위치된 후방 방향으로 회전하여 제1작동기(11)게 된다.The reinforcing member 50 is lifted or lowered together with the apparatus bracket 12 together with the boom stand 10. When the boom stand 10 is rotated upwardly, the rotating plate 40 connected to the reinforcing member 50, And the upper portion of the rotary plate 40 is rotated in the backward direction in which the tractor is located, so that the first actuator 11 is caused.

반대로, 상기 붐대(10)가 하부로 회전하면 보강부재(50)와 연결된 회전판(40)의 하부가 트랙터가 위치된 후방 방향으로 회전하고, 회전판(40)의 상부는 작업기(30)가 위치된 전방 방향으로 회전하게 된다.The lower portion of the rotary plate 40 connected to the reinforcing member 50 is rotated in the rearward direction where the tractor is positioned and the upper portion of the rotary plate 40 is located at the position where the working machine 30 is located Thereby rotating in the forward direction.

이러한, 상기 제1작동기(11)의 붐대(10) 위치조정 작동은 제1작동기(11)의 제1실린더로드(11b)의 인출입 작동으로 작업기(30)를 상하 위치 조정 후 작업기(30)의 바닥면을 작업면과 수평을 이루거나 경사지게 위치시켜 작업기(30)에 내부에 작업물을 적재시킬 수 있도록 조정할 수 있는 것이다.The operation of adjusting the position of the boom bar 10 of the first actuator 11 is performed by the operation of the working machine 30 after adjusting the vertical position of the working machine 30 by the drawing operation of the first cylinder rod 11b of the first actuator 11, So that the work can be loaded on the work machine 30 by placing the bottom surface of the work machine 30 in a horizontal or inclined position with respect to the work surface.

이로써, 상기 작업기(30)의 위치 조정을 위하여 로우더(100) 전체를 움직여야 하는 붐대(10)의 위치조정시 제1작동기(11)의 작용력이 회전판(40)의 회전에 의해 소멸되어 보강부재(50)에 붐대(10)의 작동으로 인한 작용력이 전달되지 않게 되어 휨 현상이 발생되지 않아 구조적 변형이 발생되지 않는 특징이 있다. The force of the first actuator 11 is canceled by the rotation of the rotary plate 40 when adjusting the position of the boom rope 10 to move the entire loader 100 in order to adjust the position of the working machine 30, 50 does not transmit an action force due to the operation of the boom bar 10, and thus does not cause a warping phenomenon, thereby causing no structural deformation.

이상에서는 본 발명을 특정의 바람직한 실시예를 예를들어 도시하고 설명하였으나, 본 발명은 상기한 실시예에 한정되지 아니하며 본 발명의 정신을 벗어나지 않는 범위내에서 당해 발명이 속하는 기술분야에서 통상의 지식을 가진자에 의해 다양한 변경과 수정이 가능할 것이다.While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limited to the embodiments set forth herein.
