콤바인용 예취날 고정장치Cutting blade fixing device for combine

본 고안은 농가의 벼 수확용으로 사용되는 콤바인의 예취날 고정장치에 관한 것으로 예취날에 볏짚이나 흙이 끼어 발생하는 마모로 인해 예취날의 틈이 벌어져서 벼의 밑부분이 고르게 베어지지 못하는 문제점을 해결하기 위한 콤바인용 예취날 고정장치에 관한 것이다.The present invention relates to a cutting blade fixing device for combine harvesters used for harvesting rice of farmers to solve the problem that the bottom of the rice is not cut evenly due to the gap of the cutting blade caused by abrasion caused by rice straw or soil on the cutting blade. A mowing blade fixing device for combines.

작업성의 향상과 인력의 부족으로 인해 낫으로 수작업하여 베던 벼를 제1도와 같이 근래는 자동으로 벼를 베고 탈곡까지 하는 콤바인이 보급되어 바쁜 추수시의 농가 일손을 돕고 있다.Due to the improvement of workability and lack of manpower, a rice harvester, which has been hand-crafted with a sickle, is now being used as a first-class combine to automatically harvest and thresh rice to help farmers in busy harvesting.

근래 농가는 2부작으로 농사를 짖는 방식으로 변모해 가고 있으며, 이에 따라 추수시 벼를 벨 때 논바닥 가까이 벼의 밑부분을 베어 논갈이나 로터리 작업시 논바닥의 평탄작업이 용이하게 이루어질 수 있도록 하고 있다.In recent years, farmhouses have been transformed into a two-part crop by barking farming, so that when harvesting rice, the bottom of the rice is cut near the bottom of the rice paddy so that the rice paddy can be easily flattened when the rice field or the rotary work is done. have.

이러한 종래의 콤바인(1)은 로울러벨트(2)에 의해 질퍽한 논바닥에 빠지지 않고 작업이 가능하며 제2도와 같은 예취날(6)이 전방에 부착되 전진시 벼가 베지고 베진 벼는 디바이더기(3)와 이송장치(4)에 의해 탈곡장치(5)로 이송되며 탈곡된 벼는 일정량씩 포대에 담겨지게 된다.This conventional combine (1) can work without falling into the paddy field by the roller belt (2) and the cutting blade (6) as shown in Figure 2 is attached to the front when the rice is cut and the rice is a divider ( 3) and the transfer device 4 is transferred to the threshing apparatus 5 and the threshed rice is contained in a bag by a predetermined amount.

콤바인(1)의 전진시 좌우 유동으로 벼를 베는 예취날(6)은 제3도와 제4도에서와 같이 콤바인(1)의 크기에 따라 20여개의 쪽날이 지지대(7)에 축(7a)으로 결합되 상하예취날(6)을 형성하며 상기 상하예취날(6)은 콤바인(1)에 고정된 밑판(8)의 일측단에 하부가이드판(9a)이 결합축(10)으로 결합되고 그 상측에 상부가이드판(9)이 위치하게 대향측으로 다수개의 간격조절와셔(11)로 높이가 조절되는 고정판(12)을 결합축(13)으로 고정하고 고정판(12)의 측단에 상부가이드판(9)을 고정한 다음 상하부가이드판(9)의 사이에 예취날(6)이 끼워지게 지지대(7)가 안쪽으로 삽입되 결합되며 이러한 밑판(8)과 고정판(12)은 예취날(6)의 길이에 따라 다수개가 결합되 예취날(6)을 잡아주게 된다.The cutting blade 6 which cuts rice by the left and right flow when the combine 1 advances, as shown in FIG. 3 and FIG. 4, has about 20 blades with the shaft 7a on the support 7 according to the size of the combine 1. The upper and lower cutting blades 6 are combined to form upper and lower cutting blades 6, and the lower guide plate 9a is coupled to the coupling shaft 10 at one end of the bottom plate 8 fixed to the combine 1. The upper guide plate 9 is fixed to the fixing plate 12, the height of which is adjusted by a plurality of gap adjusting washers 11 to the opposite side to the coupling shaft 13 and the upper guide plate 9 on the side end of the fixing plate 12 After fixing the upper and lower guide plate (9) between the cutting blade (6) is inserted into the support 7 is inserted into the inner side and the bottom plate (8) and the fixed plate 12 is a plurality depending on the length of the cutting blade (6) The dog is combined to hold the mowing blade (6).

상기와 같은 예취날(6)은 양측단의 좌우이송판(14)에 콤바인(1)의 동력으로 좌우 유동하는 링크축(15)이 끼워져 상하예취날(6)이 서로다른 방향으로 좌우 유동함으로써 쪽날의 사이로 삽입되는 벼를 베게 되는 것이다.As described above, the cutting blade 6 is fitted with a link shaft 15 which flows left and right by the power of the combine 1 to the left and right transfer plates 14 at both ends thereof, and the upper and lower cutting blades 6 move left and right in different directions between the blades. The rice to be inserted is to be cut.

이러한 상하예취날(6)은 지지대(7)가 상하부가이드판(9, 9a)의 안쪽으로 결합되고 예취날(6)이 상하부가이드판(9, 9a)에 밀착되게 끼워져 이탈이 방지된 상태에서 상하예취날(6)이 좌우 유동해 상하부가이드판(9, 9a)과 밀착되는 부위의 마모와 상하예취날(6)과의 밀착부위에 마모가 발생하여 상하예취날(6)에 틈이 벌어지게 되고 흙이나 볏짚이 예취날(6)틈에 끼어 마모를 가속화하므로 벼의 절단력이 떨어지게 되고 콤바인(1)의 빠른 전진속도에 맞게 벼를 절단하지 못하여 벼의 밑부분이 길쭉하거나 높이가 고르지 못하게 베어지며 벼가 탈곡장치(5)로 유입되어 탈곡시 벼의 밑부분 길이가 고르지 못해 볏짚이 탈곡장치(5)의 탈곡통으로 딸려들어가 탈곡효율을 떨어트리는 문제점이 있었다.The upper and lower cutting blade 6 has a support 7 is coupled to the inside of the upper and lower guide plates 9 and 9a, and the cutting blade 6 is fitted in close contact with the upper and lower guide plates 9 and 9a to prevent the upper and lower cutting blades from being separated. (6) flows left and right, abrasion occurs in the areas in close contact with the upper and lower guide plates (9, 9a) and the close contact with the upper and lower cutting blades (6) to open a gap on the upper and lower cutting blades (6), and soil or rice straw The cutting force of the rice decreases as it accelerates abrasion by cutting into the cutting blade (6), and the bottom of the rice is elongated or unevenly cut because the rice cannot be cut at the fast forward speed of the combine (1). (5) was introduced into the threshing barrel of the threshing device (5) because the bottom length of the rice during the threshing was uneven to reduce the threshing efficiency.

또한 상하부가이드판(9, 9a)과의 마찰부위가 쉽게 마모되어 예취날(6)의 수명이 오래가지 못하며 마찰부위의 틈을 줄이고자 고정판(12)이 결합되는 간격조절와셔(11)를 틈에 맞게 빼내어 사용하고 있으나 볏짚과 흙이 많이 끼어 큰효과를 거두지 못하는 실정이며 콤바인이 질퍽한 논에 빠지면 빠진 깊이에 의해 예취날이 논흙에 파묻혀 흙을 베게되므로 마모가 더욱 쉽게 일어나는 문제점이 있었다.In addition, the friction part with the upper and lower guide plates (9, 9a) is easily worn, so that the life of the cutting blade (6) does not last long, and the gap adjusting washer (11) to which the fixing plate (12) is coupled to reduce the gap of the friction part is in the gap. Although it is used to pull out properly, the straw straw and soil are stuck a lot, and the effect is not great. When the combine falls into the paddy field, the cutting blade is buried in the paddy soil and the soil is cut off, causing wear more easily.
