Description

작물 줄기 제거장치{STOLON REMOVAL APPARATUS FOR CROPS}Crop Stem Removal Device {STOLON REMOVAL APPARATUS FOR CROPS}

본 발명은 작물 줄기 제거장치에 관한 것으로, 더욱 상세하게는 고구마 등 지층 표면을 따라 넓은 영역에 걸쳐 뻗은 식물의 줄기를 절단하여 제거하는 작물 줄기 제거장치에 관한 것이다.The present invention relates to a crop stem removing device, and more particularly, to a crop stem removing device for cutting and removing the stem of the plant extending over a wide area along the stratum surface such as sweet potatoes.

일반적으로 수박, 참외 등 수확을 마친 채소밭을 다음 농사를 위하여 일구기 위한 이전의 과정이나 뿌리 생물인 고구마 등을 채취하기 이전의 과정에서는 밭의 전체 면적에 분포된 줄기를 제거하는 작업을 필요로 한다.In general, the process of cultivating the harvested vegetable garden, such as watermelon and melon, for the next farming or removing the sweet potato, which is the root organism, requires the removal of stems distributed over the entire area of the field.

이들 줄기는 밭의 두둑과 골에 관계없이 지층 표면을 따라 넓은 영역에 걸쳐 뻗쳐 있을 뿐 아니라, 이웃하는 다른 줄기들과 서로 엉킨 상태로 존재하는데, 이러한 덩굴이 제거되지 아니한 상태로 경우기 또는 트랙터를 이용하여 쟁기질 등을 수행하면, 기계와 함께 덩굴의 엉킴 정도가 더욱 심화하여 작업이 어려울 뿐 아니라, 기계장치의 고장을 초래할 수도 있다.These stems not only stretch over a large area along the stratum surface, irrespective of the ridges and valleys of the field, but are also entangled with other neighboring stalks, and these vines have not been removed. When plowing is carried out using a machine, the degree of entanglement of the vines with the machine is intensified, which makes the operation difficult and may also cause a breakdown of the mechanical device.

이러한 이유에서 실시되는 줄기 제거는, 작업자들이 일부 영역 단위로 분담하여 줄기를 거둬내는 수작업의 형태로 이루어져 왔고, 이는 많은 작업자의 노동이 필요로 할 뿐 아니라, 많은 작업시간 및 부수적인 뒤처리 작업이 요구되는 문제점이 있다.Stem removal for this reason has been done in the form of manual labor, in which workers divide the trunks in some area, which not only requires a lot of labor, but also requires a lot of work time and ancillary post-processing work. There is a problem.

이를 해소하기 위해, 당 분야에서는 지층 표면에 넓게 전개하여 형성된 줄기를 제거할 수 있는 장치들을 개발, 및 보급하여, 줄기의 제거에 따른 작업성과 편리성을 확보하고 있다.In order to solve this problem, the art has developed and disseminated devices capable of removing stems formed by spreading widely on the stratum surface, thereby ensuring workability and convenience according to the removal of stems.

그런데, 종래 줄기 제거장치의 줄기 제거부는, 회전축에 상호 다른 길이를 갖는 절단날을 방사구조로 배치하여 절단날 자체의 길이를 통해 작업 깊이가 설정되도록 한 형태이다.By the way, the stem removing unit of the conventional stem removing device is a form in which the working depth is set through the length of the cutting blade itself by arranging cutting blades having different lengths on the rotating shaft in a radial structure.

따라서, 농민들은 각기 다른 길이의 절단날을 구입, 및 보관하여 때때로 이를 교체하여야 하므로, 각기 다른 길이의 절단날을 구입함에 따른 경제적인 부담이 가중되고, 또 이를 보관, 및 휴대하여 해당 절단날의 마모시 마모된 절단날과 동일 규격의 절단날을 교체하여야 하는 번거로움이 발생된다. 특히, 절단날은 줄기의 절단과정에 마모가 빈번히 발생되는 소모 교체품인 관계로, 이러한 문제점은 더욱 심화된다. Therefore, farmers need to purchase and store cutting blades of different lengths and sometimes replace them, thus increasing the economic burden of purchasing cutting blades of different lengths, and storing and carrying them. When worn, the hassle of having to replace the cutting blade of the same specification as the worn cutting blade. In particular, since the cutting blade is a consumable replacement product in which wear occurs frequently during the cutting of the stem, this problem is further exacerbated.

또한, 종래 줄기 제거장치는 절단날을 설치하는 위치가 정해진 관계로, 작업자가 작업을 요하는 작업폭에 따라 절단날의 설치 위치를 변경하여 작업폭을 임의 설정하는 것이 불가능한 문제점을 갖고 있다.In addition, the conventional stem removing apparatus has a problem that it is impossible to arbitrarily set the working width by changing the installation position of the cutting blade according to the working width required by the operator because the position to install the cutting blade is fixed.

상기한 문제점을 해소하기 위해 안출된 본 발명의 목적은, 회전축에 방사구조로 설치된 절단날들을 통해 지층 표면을 따라 넓은 영역에 걸쳐 뻗은 식물의 줄기를 절단하여 제거하는 줄기 제거부를 구현함에 있어, 두둑과 골를 포함하는 작업영역에 따라 절단날들의 배치 간격을 재설정하여 작업폭의 임의 조절하는 것이 가능하도록 한 작물 줄기 제거장치를 제공함에 있다.In order to solve the above problems, an object of the present invention is to implement a stem removal unit for cutting and removing a stem of a plant extending over a large area along a stratum surface through cutting blades installed radially on a rotating shaft.

예컨대, 도 5에서 보는 바와 같이 회전축(21)의 중앙구간에 직경이 상대적으로 작은 고정휠(23)을 설치하면 이 고정휠(23)에 설치된 절단날(24)은 상대적으로 얕은 작업깊이를 갖게 된다.For example, as shown in FIG. 5, when a fixed wheel 23 having a relatively small diameter is installed in the center section of the rotating shaft 21, the cutting blade 24 provided at the fixed wheel 23 has a relatively shallow working depth. do.

그리고, 회전축의 양측구간에 직경이 상대적으로 큰 고정휠(23)을 설치하면 이 고정휠에 설치된 절단날(24)은 상대적으로 깊은 작업깊이를 갖는다.In addition, when the fixed wheel 23 having a relatively large diameter is provided at both side sections of the rotating shaft, the cutting blade 24 provided at the fixed wheel has a relatively deep working depth.

따라서, 본 발명에 따른 작물 줄기 제거장치(1)의 줄기 제거부(20)는, 지형에 적합한 형태로 절단날(24)의 진입깊이를 변경하는 것이 가능하므로, 줄기의 제거과정에 절단날(24)이 지층 표면에 진입하여 고구마 등의 작물에 직접적인 손상을 가하거나, 절단날(24)이 지층 표면에 형성된 줄기에 도달하지 못하여 줄기를 제거하지 못하는 현상이 예방될 수 있다.Therefore, the stem removing unit 20 of the crop stem removing device 1 according to the present invention, since it is possible to change the depth of entry of the cutting blade 24 in a form suitable for the terrain, the cutting blade ( When 24) enters the stratum surface and directly damages crops such as sweet potatoes, or the cutting blade 24 does not reach the stem formed on the stratum surface, the phenomenon of removing the stem may be prevented.

특히, 본 발명은 상대적으로 길이가 짧은 절단날(24)을 채택하면서도, 깊은 작업깊이를 갖도록 설정할 수 있어서, 절단날(24)의 편심 회전에 의해 회전축(21)이 요동하고, 이에 따라 장치(1) 전체가 요동하여 작업자의 육체적 피로를 가중시키는 현상 또한 억제될 수 있다.In particular, the present invention can be set to have a deep working depth while adopting a cutting blade 24 having a relatively short length, so that the rotating shaft 21 is oscillated by the eccentric rotation of the cutting blade 24, and thus the device ( 1) The phenomenon that the whole body fluctuates and adds to the worker's physical fatigue can also be suppressed.

그리고, 본 실시예에서는 회전축(21)에 배치되는 고정휠(23)의 직경을 달리 설정하여 절단날(24)에 의한 작업깊이를 설정하는 관계로, 단일 규격의 절단날(24)을 공용하면서도 각기 다른 작업깊이를 갖도록 하는 것이 가능하다.In this embodiment, while setting the working depth by the cutting blade 24 by differently setting the diameter of the fixed wheel 23 disposed on the rotating shaft 21, while sharing a single cutting blade 24 of a single standard It is possible to have different working depths.

그리하여, 작업자는 줄기의 제거를 요하는 두둑의 폭이나 골의 깊이에 따라, 이에 적합한 폭을 갖는 간극부재와 적합한 직경을 갖는 고정휠을 채택하여 줄기 절단부(20)를 구성함으로써, 줄기의 제거를 요하는 지층 표면에 적합한 줄기 제거부를 형성하는 것이 가능하다.Thus, the operator employs a gap member having a suitable width and a fixed wheel having a suitable diameter according to the width of the rib or the depth of the valley requiring the removal of the stem to form the stem cutout 20, thereby eliminating the stem. It is possible to form a stem removal section suitable for the required strata surface.
