KT—3谷物联合收获机(简称KT—3下同)在使用中故障多,损失大,工效低。我们为用好该机进行了一系列的改装,取得了较好的效果。现将为适应麦收进行的改装介绍如下: 提高工效的改装 KT—3原割幅为3米,用东方红—54(75)牵引,挂低档负荷不满,工效低;挂高档机组振动大,故障多,损失大。针对上述情况,我们用同样规格的工字钢和角钢将收割台接长,使其工作幅宽由3米增加到4米。刀杆可取一断旧刀杆焊接,锉平后铆上刀 KT-3 grain combine harvester (referred to as KT-3 the same below) in the use of more failures, loss, low efficiency. We made good use of the aircraft for a series of modifications, and achieved good results. The modifications to be adapted to the wheat harvest are as follows: Improve the ergonomics modification KT-3 original cutting width of 3 meters, with the East Red -54 (75) traction, hanging low gear load dissatisfaction, low efficiency; hanging high-grade unit vibration, fault More, big loss. In response to the above situation, we use the same specifications of the I-beam and angle of the harvesting Taiwan then long, so that its working width increased from 3 meters to 4 meters. Arbor can take a broken old knife welding, riveting the file after the flat knife
