Description

트랙터용 로터베이터{rotavator}Rotorator for tractors {rotavator}

본 발명은 트랙터용 로터베이터에 관한 것으로서, 보다 상세하게는 트랙터의 상하 움직임에 영향을 받지 않고, 무논의 바닥을 일정한 깊이로 곤죽상태로 만들 수 있도록 된 새로운 구성의 트랙터용 로터베이터에 관한 것이다.The present invention relates to a tractor rotor for a tractor, and more particularly to a tractor rotor for a new configuration to be able to make the bottom of Munnon to a certain depth without being affected by the vertical movement of the tractor.

일반적으로, 모를 심을 수 있도록 논바닥을 갈아엎어 곤죽상태로 만드는 데 사용하는 로터베이터는 트랙터의 후방에 승강가능하게 장착된 프레임에 다수개의 로터리날을 설치하여 구성된다. 이때, 상기 프레임은 트랙터 후방에 장착된 링크기구에 장착되어 링크기구에 연결된 유압실린더에 의해 승강되며, 상기 로터리날은 트랙터의 변속기에 장착된 PTO(power take off)에 연결되어, 엔진구동력에 의해 구동된다.In general, a rotorbait used to plow a rice field so that it can be planted without knowing it is constructed by installing a plurality of rotary blades on a frame mounted removably at the rear of the tractor. At this time, the frame is mounted on the link mechanism mounted on the rear of the tractor is lifted by a hydraulic cylinder connected to the link mechanism, the rotary blade is connected to the power take off (PTO) mounted on the transmission of the tractor, by the engine driving force Driven.

따라서, 상기 로터리날을 논바닥에 일정깊이로 박은 상태에서 고속으로 회전시키면 이 로터리날이 논바닥을 파헤치므로, 트랙터로 로터베이터를 끌고다니면서 논바닥 전체를 모를 심을 수 있는 굴곡이 없고 평탄한 곤죽상태로 만들게 된다.Therefore, if the rotary blade is rotated at a high speed while being driven to the paddy ground at a high speed, the rotary blade digs the paddy ground, so that there is no bending and flat gruel that can plant the entire paddy ground while dragging the rotorbator with a tractor. Will be brought to a state.

그런데, 이러한 로터베이터는 상기 유압실린더를 이용하여 로터베이터 프레임을 승강시키므로써, 상기 로터리날이 논바닥을 파내는 깊이를 조절할 수 있으며, 유압실린더가 신축되지 않는 한, 로터베이터는 트랙터에 고정되어 일체로 움직이게된다. 따라서, 트랙터를 운전하여 로터베이터를 끌고 다닐 때, 트랙터가 논이나 밭에 형성된 골이나 둔덕에 걸려 상하로 흔들리면, 상기 로터베이터가 트랙터와 함께 상하로 승강되므로, 논바닥이 일정한 깊이로 파헤쳐지지 않고, 너무 많이 파헤쳐지거나, 전혀 파헤쳐지지 않는 곳이 생기게 되는 문제점이 있었다. 특히, 이와같이 평탄화가 되지 않은 논에 이앙기로 모를 심을 경우, 모가 논바닥에 정확히 심어지지 않아서 뜨게 되는 등의 문제점이 있었다.By the way, by using the hydraulic cylinder to lift the rotor frame by lifting the rotor, the rotary blade can adjust the depth to dig the rice paddy, unless the hydraulic cylinder is stretched, the rotor is fixed to the tractor integral To be moved. Therefore, when driving the tractor and dragging the rotorbait, if the tractor is shaken up and down due to the valleys or mounds formed in the paddy field or the field, the rotorbait is lifted up and down together with the tractor, so that the paddy field is not dug to a certain depth. There was a problem that, too much dug, or not dug at all. In particular, when planting rice transplanters in rice fields not flattened in this way, there was a problem such that the seedlings are not planted correctly on the rice paddy floor and floated.

또한, 트랙터가 심하게 흔들려서 로터베이터가 갑자기 하강될 경우, 로터베이터의 로터리날이 논바닥에 심하게 박히게 되며, 이러한 경우, 로터리날이나 로터리날을 구동하는 트랙터의 엔진에 갑자기 심한 부하가 걸려, 고장이 발생될 수 있는 문제점이 있었다.In addition, if the tractor is severely shaken and the rotorbator is suddenly lowered, the rotor blades of the rotorbaiter become severely stuck on the rice paddy field. In this case, the engine of the rotary blade or the tractor driving the rotary blades suddenly receives a heavy load, thereby causing trouble. There was a problem that could occur.

한편, 상기 로터베이터 프레임에는, 프레임의 후방을 가려서 로터리날에 의해 흩뿌려지는 흙이 사방으로 튀는 것을 방지할 수 있도록 된 덮개가 구비된다. 이 덮개는 판형상으로 구성된 것으로, 그 상단이 상기 프레임의 후방에 회동승강가능하게 힌지결합되며 그 하단이 지면에 닿아, 상기 로터리날에 의해 파헤쳐진 흙이 사방으로 튀는 것을 방지하는 기능을 한다.On the other hand, the rotor bait frame is provided with a cover to prevent the soil scattered by the rotary blades to cover the rear of the frame to splash in all directions. The cover has a plate shape, the upper end of which is hinged rotatably in the rear of the frame, and the lower end of the cover touches the ground, and serves to prevent the soil dug by the rotary blades from splashing in all directions.

또한, 경우에 따라, 상기 덮개 이외에, 로터베이터 프레임의 후방에 써레를 장착하여, 로터베이터로 무논의 바닥을 파헤친 후, 써레를 이용하여 평탄화작업을 하기도 한다.In addition, in some cases, in addition to the lid, a harrow may be attached to the rear of the rotorbait frame to dig the bottom of Munon with the rotorbate, and then the harrow may be used for flattening.

본 발명은 상기의 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 트랙터의 상하 움직임에 영향을 받지 않고, 무논을 일정한 깊이로 곤죽상태로 만들 수 있을 뿐 아니라, 로터리날이나 엔진에 심한 부하가 걸려 고장의 발생을 방지할 수 있도록 된 새로운 구성의 트랙터용 로터베이터를 제공하는 것이다.The present invention is to solve the above problems, the object of the present invention is not affected by the vertical movement of the tractor, can not only munchon Munon to a certain depth, but also put a heavy load on the rotary blade or engine It is to provide a rotor rotor for a new configuration that can prevent the occurrence of failure.
