구근작물의 줄기 분쇄장치{STALK SHATTERING DEVICE OF A BULB PLANT}Stem crusher of bulb crops {STALK SHATTERING DEVICE OF A BULB PLANT}

본 발명은 구근작물의 줄기 분쇄장치에 관한 것으로, 더욱 상세하게는 두둑에 위치한 작물의 줄기를 분쇄시킴과 더불어 고랑에 위치한 작물의 줄기까지도 확실하게 제거할 수 있으며, 특히 줄기의 분쇄시 줄기가 감겨지지 않고 확실하게 절단되도록 한 트랙터 부착용 구근작물의 줄기 분쇄장치에 관한 것이다.The present invention relates to a stem grinding device of a bulb crop, and more particularly, it is possible to reliably remove even the stem of the crop located in the furrow, as well as grinding the stem of the crop located on the ridge, especially when the stem is wound The present invention relates to a stem grinding device for a tractor attachment bulb crop that is reliably cut without being supported.

일반적으로 구근작물의 수확은 표층의 줄기를 걷어낸 후 두둑속의 구근을 수확하게 되고, 이와 같은 구근식물의 수확시에는 구근식물의 줄기를 거둬내는 작업이 필수적으로 행해져야 하는 바, 종래에는 낫이나 호미를 사용하여 일일이 줄기를 거둬내는 인력에 의한 방식과, 트랙터나 경운기 또는 승용 및 보행관리기에 장착된 제초기 및 분쇄기에 의한 기계적인 방식이 있었다.In general, the harvesting of the bulbous crop is to harvest the bulbs of the patter after removing the stem of the surface layer, and harvesting the stems of the bulbous plant must be performed when harvesting such bulbous plants. There was a method of manure harvesting stems using a hoe and a mechanical method of mowers and grinders mounted on tractors, tillers or passenger and walk managers.

상기한 인력방식은 인건비 및 생산성의 저하로 인하여 현재 기계방식에 의존하여 구근식물의 줄기를 분쇄하고 있는 실정이며, 예로서 대한민국 등록실용신안 제0221937호에서와 같이, 제초기의 칼날 회전시 사고위험을 방지하고자 회전축의 방향을 반대로 바꾸도록 기어박스가 설치되어 있으며, 제초기의 후단에 지면과 칼날의 높이를 작업여건에 맞추도록 높이조절바퀴가 구비된 제초기가 개시되어 있다.The above-mentioned manpower method is pulverizing the stem of the bulbous plant depending on the current machine method due to the decrease in labor cost and productivity. For example, as in the Republic of Korea Utility Model No. 0221937, the risk of accidents when rotating the blade of the mower In order to prevent the gearbox is installed to reverse the direction of the rotation axis, the mower is provided with a height adjusting wheel to adjust the height of the ground and the blade to the working conditions at the rear end of the mower.

그러나, 상기의 기술은 높이조절바퀴의 조작시 작업기를 정지시킨 상태로 조작하여야 함에 따라 번거럽고 불편하였으며, 고랑에 위치한 줄기의 절단이 어려워 효율적인 작물의 줄기 절단을 기대할 수 없는 문제점이 있었다.However, the above technique has been cumbersome and inconvenient as it has to be operated in a state in which the work machine is stopped when the height adjustment wheel is operated, and it is difficult to cut the stem located in the furrow, and thus there is a problem in that the stem cutting of the efficient crop cannot be expected.

또한, 대한민국 등록실용신안 제0207000호에서는 회전축의 중앙쪽에 배치되는 칼날의 길이를 양측면에 배치되는 칼날의 길이보다 짧게하여 두둑의 줄기를 제거할 수 있도록 하고 있다.In addition, the Republic of Korea Utility Model Registration No. 0207000, the length of the blade disposed on the center of the rotation axis is shorter than the length of the blade disposed on both sides to remove the stem of the ridge.

그러나, 상기의 기술은 양측의 칼날이 중앙쪽에 비해 길게 형성됨에 따라 회전축을 감싸는 커버체가 커질 수 밖에 없어 고랑에 위치한 줄기는 절단이 가능하나 중앙쪽에 위치한 칼날은 등커버체와 간격이 많이 떨어져 있으므로 즐기자체가 커버체의 내부로 유입되면서 회전축에 감기거나 칼날에 엉키는 등 줄기의 절단이 불가능하게 되는 단점이 있었으며, 더욱이 줄기가 회전축에 감김에 따라 양측에 위치한 고랑측 줄기 절단용 칼날도 그 소용이 없어지게 됨으로써 줄기 분쇄기로서의 기능을 상실하게 되는 문제점이 있었으며, 이에 따라 작업자가 수시로 회전축에 감겨진 작물의 줄기를 제거한 후 작업하여야 하는 관계로 작업시간이 증가될 뿐만 아니라 작업효율이 저하되는 단점이 있었다.However, the above-mentioned technology is that as the blades on both sides are formed longer than the center side, the cover body surrounding the rotating shaft is inevitably larger, so that the stem located in the furrow can be cut, but the blade located at the center side is spaced apart from the back cover body so that it is enjoyed. There was a disadvantage in that the cutting of the stem was impossible such as being wound on the rotating shaft or entangled in the blade as it was introduced into the cover body. Moreover, the cutting blade for cutting the furrow on both sides has no use as the stem is wound on the rotating shaft. As a result, there was a problem that the function as a stem grinder is lost, and as a result, the worker must work after removing the stem of the crop wound around the rotating shaft from time to time, thereby increasing the working time and reducing the working efficiency.

본 발명은 상기한 문제점을 해결하기 위하여 창안된 것으로, 본 발명의 목적은 두둑과 고랑에 위한 작물의 줄기를 확실하게 제거할 수 있으며, 특히 줄기의 분쇄시 회전칼축에 줄기가 감기거나 엉키지 않는 상태로 확실하게 분쇄되어 짐으로써 작업능률이 좋아지며, 단시간내에 작업을 마루리 할 수 있어 고구마, 감자 등 구근작물을 수확하기에 용이한 트랙터 부착용 구근작물의 줄기 분쇄장치를 제공하는 데 있다.The present invention was devised to solve the above problems, an object of the present invention can reliably remove the stem of the crop for the toads and furrows, in particular the state that the stem is not wound or tangled on the rotary shaft during the grinding of the stem It is to provide a stem crushing device of a bulb attachment crop for tractors that can be easily harvested bulbous crops such as sweet potatoes and potatoes because the work efficiency can be improved by being surely ground.
