Description

이중 회전날이 한 쌍으로 구비된 제초기 작업봉 헤드 {head of working rod for weeder}Mower working head with pair of double rotary blades {head of working rod for weeder}

본 발명은 제초기의 작업봉 헤드에 관한 것으로 논과 밭, 과수원 등의 밭두둑에 자라는 잡초를 효과적으로 제거할 수 있게 제초기의 작업봉 헤드에 한 쌍의 이중 회전날을 구비한 작업봉 헤드에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a workbench head of a mower, and more particularly, to a workbench head having a pair of double rotary blades on a workbench head of a weeder to effectively remove weeds growing on fields such as rice fields, fields, and orchards.

종래의 제초기의 작업봉의 헤드에는 한 개의 제초용 회전날이 구비되어 있어 제초작업을 단순히 잡초의 줄기와 잎을 잘게 절단하여 두둑의 지표면에 흩어 놓는 형태로 작업이 이루지기 때문에 제초가 효과적이지 못하였다.The head of the rod of the conventional weeder is equipped with a rotary blade for weeding and weeding was not effective because the work is done in the form of simply cutting the stem and leaves of the weeds and scattering them on the ground surface of the pits. .

그리고 작업봉의 헤드에 장착된 회전날의 날면에 작은 돌멩이 등이 부딪쳐도 회전날이 회전을 멈추면서 회전날의 원심력에 의하여 작업봉의 헤드가 급히 옆으로 쏠리게 되어서 자칫 회전날에 작물이 절단되게 하는 문제점이 있었으나, 본 발명은 작업봉 헤드에 서로 반대 방향으로 회전하는 이중 회전날을 한 쌍으로 구비하여 이러한 문제를 해결한 것이다.And even if small stones hit the blade surface of the rotating blade mounted on the head of the working rod, the rotating blade stops rotating and the head of the working rod is urgently pushed to the side by the centrifugal force of the rotating blade, which causes crops to be cut on the rotating blade. However, the present invention solves this problem by having a pair of double rotary blades to rotate in the opposite direction to the working head head.

상기 이중 회전날이 지표면을 일정한 깊이로 파헤치게 하기 위하여 삼발형 지지판에 세 개의 날개를 나선형으로 부착하여 이중 회전날을 구성하고, 이와 같은 이중 회전날을 한 쌍으로 작업봉의 헤드에 장착하여 서로 반대로 회전하게 하였다.In order to make the double rotary blade to dig the surface to a certain depth, three blades are helically attached to the tricycle support plate to form a double rotary blade, and such a double rotary blade is mounted on the head of the working rod in pairs to reverse each other. Rotated.

더욱 상세하게는 종래의 제초기는 수평으로 회전하는 한 개의 회전날이 장착되어 단순히 잡초의 줄기와 잎을 절단하여 두둑의 사방에 흩어 놓는 작업이었으나, 본 발명에서는 이중 회전날에 의하여 잡초의 잎과 줄기를 잘게 절단하고, 지지판에 부착되는 회전날의 날개를 나선형으로 구성이 되어 있으므로 이중 회전날이 지표면을 일정한 깊이로 파헤쳐서 잡초의 뿌리도 잘게 절단하면서 절단된 잎과 줄기와 함께 흙속에 묻는 작업도 동시에 이루어지게 하였다.More specifically, the conventional weeding machine was equipped with one rotary blade rotating horizontally and simply cutting the stems and leaves of the weeds and scattering them on all sides of the toad, but in the present invention, the blades and the stems of the weeds by the double rotary blades. Cutting the blade, and the blade of the rotary blade attached to the support plate is composed of a spiral, so the double rotary blade digs the ground surface to a certain depth to cut the roots of the weeds finely while also buried in the soil with the cut leaves and stems It was done at the same time.

그리고 상기와 같은 작용을 더욱 효과적으로 하기위하여 이중 회전날을 한 쌍으로 작업봉 헤드에 장착하고, 잡초를 쉽게 절단하도록 지지판을 삼발형으로 형성하여 날면을 요철형으로 구성을 하고, 역시 날개의 날면도 요철형으로 형성한 것을 특징으로 하였다.And in order to more effectively perform the above-mentioned action, a double rotary blade is mounted on the working rod head in pairs, and the support plate is formed in a triangular shape to easily cut the weeds, so that the blade is formed into an uneven shape, and also the blade surface of the wing It was characterized by being formed in an uneven form.

서로 반대 방향으로 회전하는 이중 회전날을 작업봉 헤드의 양측이 장착하여 회전날의 날개에 돌멩이 등 물체가 부딪치었을 때에 회전날의 회전이 멈추면서 회전날의 원심력이 한쪽으로 편중되지 않고 양측으로 동일하게 발생하게 되어 헤드가 한쪽으로 급히 쏠림이 없음으로 작물이 회전날에 절단되는 문제점이 없게 한 것이다.When both sides of the rod head are equipped with dual rotary blades rotating in opposite directions, when objects such as stones hit the blades of the rotary blade, the rotation of the rotary blade stops and the centrifugal force of the rotary blade is not biased to one side. The same occurs so that there is no problem that the crop is cut on the rotary blade because the head is not rushing to one side.

그리고 본 발명의 이중 회전날을 일반 예초기의 작업봉 헤드에도 설치하여 예초기의 동력원으로 제초작업을 할 수가 있게 한 것 등에 그 목적이 있다.In addition, the dual rotary blade of the present invention is also installed on the working rod head of the general lawnmower, and the like to enable the mowing operation as a power source of the lawnmower.

종래의 제초기의 여러 문제점을 해결하기위하여 상기에서와 같이 본 발명은 이중 회전날을 작업봉 헤드에 한 쌍으로 착설하고, 이중 회전날이 서로 반대 방향으로 회전하면서 잡초의 줄기와 잎을 잘게 절단하고, 이중 회전날이 두둑의 지표면을 일정한 깊이로 파헤쳐서 잡초의 뿌리도 잘게 절단하고, 잘린 잡초의 잔해와 잡초의 뿌리를 흙속에 묻는 방법으로 작업이 동시에 이루어지게 하였다.In order to solve various problems of the conventional mower, the present invention installs a pair of double rotary blades to the working rod head, the dual rotary blades are rotated in opposite directions to each other and finely cut the stem and leaves of the weeds The double rotary blades dug up the surface of the toad to a certain depth, cutting the weed roots finely and burying the cut weeds and the roots of the weeds in the soil.

그리고 제초작업 중 회전날이 돌멩이 등 물체에 부딪쳤을 때 원심력이 한 방향으로 편중되지 아니하게 하기위하여 헤드에 한 쌍의 이중 회전날을 장착하여 원심력이 양쪽으로 동일하게 발생이 되게 하였으므로 헤드가 한 쪽으로 쏠림이 없게 되어 자칫 작물이 회전날에 의하여 절단되는 문제점이 없게 하였다.In order to prevent the centrifugal force from being biased in one direction when the rotary blade hits an object such as stones during the weeding operation, the head is tilted to one side because a pair of double rotary blades are mounted on the head so that the centrifugal force is generated equally on both sides. There is no problem that the crop is cut by the rotary blade.

더욱 상세하게는 상기 이중 회전날은 잡초를 효율적으로 절단하기위하여 날면이 요철형인 삼발형 지지판에 역시 날개의 날면이 요철형으로 형성된 세 개의 날개를 부착하여 구성되어 있고, 이중 회전날이 지면을 일정한 깊이로 파헤쳐서 잡초를 뿌리까지 효과적으로 절단을 하기 위하여 날개를 지지판에 나선형으로 부착하였다.More specifically, the dual rotary blade is configured by attaching three blades formed with an uneven shape of the blade surface of the blade to the triangular support plate having an uneven shape in order to efficiently cut the weeds. The wings were spirally attached to the support plate to dig deep and effectively cut the weeds to the roots.

상기와 같이 이중 회전날의 날개가 나선형으로 구성 되어 있기 때문에 지표면을 일정한 깊이로 파헤치면서 잡초의 뿌리도 절단하고, 잘게 절단된 잡초의 잔해와 함께 흙속에 묻는 작업이 동시에 이루어지게 하기 때문에 경운의 효과도 있게 하면서 또한 제초작업을 효과적으로 이루어지게 하였다.Since the blades of the double rotary blades are constructed in a spiral shape, the roots of the weeds are also cut while digging the ground surface to a certain depth, and the work is carried out at the same time with the debris of the finely cut weeds. In addition, weeding was also effective.

그리고 본 발명의 이중 회전날의 조립구를 일반 예초기의 작업봉의 헤드에 설치를 할 수가 있도록 구성하여 본 발명의 이중 회전날을 일반 예초기의 헤드에 장착하여 제초작업을 할 수가 있게 하였다.Then, the assembly tool of the double rotary blade of the present invention is configured to be installed on the head of the working rod of the general mower so that the double rotary blade of the present invention can be mounted on the head of the general mower to mow.

상기에서와 같이 이중 회전날을 헤드의 양측에 착설하고, 잡초를 효율적으로 절단하기위하여 작업날의 날개의 날면과 날개가 부착되는 삼발형 지지판의 날면을 요철형으로 형성하고 그리고 이중 회전날의 날개는 삼발형 지지판에 나선형으로 부착하여 동 회전날이 잡초의 잎과 줄기를 잘게 절단하면서 지표면을 일정한 깊이로 파헤쳐 잡초의 뿌리도 잘게 절단하고 절단된 잡초의 줄기와 잎과 함께 흙속에 묻는 작업도 동시에 이루어지게 하여 토양을 경운하는 효과도 있게 하였다.As described above, the dual rotary blade is installed on both sides of the head, and the blade surface of the blade of the working blade and the blade surface of the triangular support plate to which the blade is attached are formed in an uneven shape so as to efficiently cut the weeds, and the blade of the dual rotary blade. Attached spirally to the triangular support plate, the copper rotary blade chops the leaves and stems of the weeds, while digging the ground surface to a certain depth, cutting the roots of the weeds, and cutting the weeds with the stems and leaves. It also had the effect of tilling the soil.

또한 본 발명의 이중 회전날을 통상의 예초기의 작업봉의 헤드에 설치하여 사용할 수가 있도록 조립구멍을 형성한 것 등을 발명의 특징으로 하였다.In addition, the feature of the invention is to provide an assembling hole so that the double rotary blade of the present invention can be installed and used in the head of a working rod of a conventional mowing machine.
