1.缩小耙片间距、增加耙片更换间管,使原耙片间距由220毫米变为169毫米,耙片总数由原来40片改为50片.相应改变支承轴承座的联接位置和利泥板的安装位置,每列增加5片圆片和5个刮泥板,从而改善了碎土性能.2.增强折翼强度在耙组梁与折翼联接处钻四个Φ20.5毫米的孔,用报废工字钢取700毫米在对应位置也钻同样的孔,在机组宽幅作业时用四个M20螺栓把耙组梁、折翼、工字钢联结在一起,形成刚性联接.作业中就可以防止折翼变形下落,保证地表平整不拉沟.3.加强牵引板取长短合适的废活塞销放入牵引板上下孔之间焊结,起支撑作用.在主牵引板左右呈三角形焊结角
1. Reduce the distance between the blades and increase the distance between the blades to change the space between the original blades to 220 mm from 169 mm, the total number of blades from 40 to 50. The corresponding changes in support bearing seat position and benefit mud Plate installation position, adding 5 discs and 5 scraper plates in each column, thus improving the crushing performance 2. Enhance the strength of the flaps At the joint of beam and flaps of the rake group, drill four Φ20.5 mm holes , With the scrapped I-beam take 700 mm at the corresponding location also drilled the same hole in the unit wide operation with four M20 bolts to rake beam, flaps, I-beam together to form a rigid connection. You can prevent the deformation of the falling wings to ensure that the formation of a smooth surface of the ditch .3 to strengthen the traction plate take the appropriate length of the waste piston pin into the traction plate between the upper and lower holes between the weld, play a supporting role in the main traction plate was triangular welding angle
