Description

농업용 로타리{ROTARY FOR FARMING}Rotary FOR FARMING

본 발명은 동력을 이용하여 경운날을 회전시켜서 농토를 경운하는 농업용 로타리에 관한 것이다.The present invention relates to an agricultural rotary for cultivating farmland by rotating a tillage blade using power.

일반적으로 농업용 로타리는 등록특허 10-0888630호 '프론트 로타리 작업기구를 가지는 작업기계'와 공개특허 10-2017-0011470호 '로타리 날 모듈' 및 등록특허 10-1932215호 '고성재배용 로타리장치' 등과 같이 소형의 경우 보조바퀴를 갖는 동력 농기계의 좌우차축에 각각 연결부를 갖는 회전축과 플랜지 및 회전축에 연결형성되는 로타리날로 이루어진 로타리날 모듈을 연결하여 차축에 의한 로타리날 묘듈의 회전으로 경운이 이루어지도록 구성되고 또 중형이나 대형의 경우 본체와 로타리날 모듈 및 동력전달축으로 이루어진 로타리를 경운기나 트렉터 등에 연결하여 경운기나 트렉터의 출력축에 의한 로터리날 모듈의 회전으로 경운이 이루어지도록 구성된다.In general, agricultural rotary is registered patent No. 10-0888630 'Working machine with a front rotary work tool', Patent Publication No. 10-2017-0011470 'Rotary blade module' and Registration Patent No. 10-1932215 'Rotary device for high-quality cultivation', etc. In the case of small size, the rotary blade module consisting of a rotary shaft having a connection part, a flange, and a rotary blade connected to the rotary shaft is connected to the left and right axles of a power agricultural machine having auxiliary wheels, and tillage is made by rotation of the rotary blade module by the axle In addition, in the case of medium or large size, the rotary blade module and the power transmission shaft are connected to a cultivator or a tractor, etc.

그러나 이들 모두는 크기를 불문하고 로타리날 모듈이 갖는 회전축이 동력전달기능을 만족할 수 있을 정도로 가늘게 형성되므로 경운작업중 잡풀이나 농사시 이용된 비닐 및 로프 등이 회전축에 쉽게 감겨서 경운작업을 어렵게 할 뿐 아니라 회전축에 긴장감 있게 감긴 잡풀을 제거하는데에도 많은 어려움이 따르게 된다.However, in all of these, regardless of the size, the rotary shaft of the rotary blade module is formed thin enough to satisfy the power transmission function. However, there is a lot of difficulty in removing weeds tightly wound around the rotating shaft.

그리고 근래에 들어서는 로타리날 모듈의 회전축을 전체적으로 굵게 형성하여 잡풀의 감김을 방지해주도록 하고 있으나, 회전축의 굵기를 전체적으로 굵게 형성해주기 위하여는 제작비용부담이 가중되고 또 회전축의 굵기가 더해진 만큼 로타리날 모듈의 부피가 늘어나 소형화에 매우 불리하며, 회전축의 굵기를 굵게 형성해주더라도 키가 큰 잡풀의 감김은 방지해주기 어려운 점을 감안할 때, 이 역시 잡풀이 회전축에 긴장감 있게 감길 시 이를 제거하는데 많은 어려움이 따르게 된다.And in recent years, the rotary shaft of the rotary blade module is made thick as a whole to prevent the winding of weeds. Considering that it is difficult to prevent the winding of tall weeds even if the thickness of the rotating shaft is made thick, this also causes a lot of difficulty in removing the weeds when they are tightly wound around the rotating shaft. do.

After inserting the axle (14) of (12), the fixing bolt (16) is tightened to connect and fix the rotary blade module (30) to the axle (14).

또한 로타리날 모듈(30)이 갖는 좌우플랜지(22)(24)에는 각기 1개 이상의 결합공(36)(38)을 형성하여 좌우결합공(36)(38) 사이에 양측에 핀공(40)을 갖는 감김방지봉(32)을 결합한 후 그 핀공(40)에 고정핀(42)을 결합하여 감김방지봉(32)을 좌우플랜지(22)(24) 사이에 고정해주도록 구성된다.In addition, one or more coupling holes 36 and 38 are formed in the left and right flanges 22 and 24 of the rotary blade module 30, respectively, and pin holes 40 are formed on both sides between the left and right coupling holes 36 and 38. After coupling the anti-winding rod 32 with

그리고 동력 농기계(12)의 후방에 연결설치되는 보조바퀴(34)는 동력 농기계(12)의 프레임에 고정된 지지봉 및 상기 지지봉 하단에 공회전하도록 연결설치되는 바퀴로 이루어져 좌우 로타리날 모듈(30)의 고속회전에 의한 경운작업시 동력 농기계(12)를 받쳐주도록 구성된다.And the auxiliary wheel 34 connected to the rear of the power agricultural machine 12 is composed of a support bar fixed to the frame of the power agricultural machine 12 and a wheel connected to the lower end of the support bar so as to be connected to the left and right rotary blade modules 30 of the It is configured to support the power agricultural machine 12 during tillage work by high-speed rotation.

본 발명은 농업용 로타리(10)의 로타리날 모듈(30)이 갖는 회전축(20)의 굵기를 회전축(20)으로서 요구되는 굵기로 가늘게 형성하면서 좌우플랜지(22()24) 사이에 감김방지봉(32)을 결합고정하여 잡풀이나 덩굴작물 등의 감김을 방지해주도록 구성되므로 저렴한 비용부담으로 잡풀감김방지기능을 부여해줄 수 있게 된다.The present invention provides an anti-winding rod ( 32) is combined and fixed to prevent weeds or creepers from being wound, so it is possible to provide a function to prevent weeds from being wound at a low cost.

또한 본 발명 농업용 로타리(10)를 이용한 경운작업시 굵기가 가는 회전축(20)을 사이에 두고 있는 2개의 감김방지봉(32)이 잡풀이나 덩굴작물 등의 감김을 방지해주게 된다.In addition, during tillage work using the agricultural rotary 10 of the present invention, two anti-winding rods 32 with a thin rotation shaft 20 interposed therebetween prevent the winding of weeds or creepers.

그리고 로타리날 모듈(30)의 좌우플랜지(22)(24) 사이에 결합고정되는 감김방지봉(32)은 경운작업시 발생되는 잡풀의 감김을 완전히 방지해줄 수 없어 키가 큰 잡풀이나 덩굴작물 등은 감김방지봉(32) 사이에 긴장감 있게 감겨지게 되는데, 이러한 경우 경운작업을 중단한 상태에서 감김방지봉(32) 사이에 갖는 넓은 공간부를 이용하여 낫이나 칼 등으로 감긴 잡풀이나 덩굴작물 등을 절단하여 제거해주거나 또는 어느 한 감김방지봉(32)을 좌우플랜지(22)(24)로부터 간단히 분리하여 감긴 잡풀이나 덩굴작물 등을 느슨하게 한 상태에서 제거해주면 되므로 감김방지봉(32) 사이에 감긴 잡풀이나 덩굴작물 등을 간단히 제거해줄 수 있게 된다.And the anti-winding rod 32 coupled and fixed between the left and right flanges 22 and 24 of the rotary blade module 30 cannot completely prevent the winding of weeds generated during tillage work, such as tall weeds or creepers, etc. The silver is wound with tension between the anti-rolling rods 32. In this case, in a state in which the tillage work is stopped, the wide space between the winding prevention rods 32 is used to remove weeds or creepers wound with a sickle or knife. The weeds wound between the anti-winding rods 32 can be removed by cutting and removing them, or simply separating one of the anti-winding rods 32 from the left and right flanges 22 and 24 to remove the wound weeds or creepers in a loose state. It is possible to easily remove vines, etc.

이상에서 설명한 바와 같이 본 발명은 그 권리범위는 전술한 실시예 및 첨부된 도면에 의해 한정되는 것은 아니고, 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 여러가지 치환, 변형 및 변경이 가능하며, 이는 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 있어서는 자명한 것이다.As described above, the scope of the present invention is not limited by the above-described embodiments and the accompanying drawings, and various substitutions, modifications and changes are possible within the scope without departing from the technical spirit of the present invention, which It is obvious to those of ordinary skill in the art to which the invention pertains.
