1.提高刀轴转速,加粗刀轴更换秸秆还田机主动或从动皮带轮,使刀轴转速增至1800转/分钟,从而使动刀片产生更大动能。为增加刀轴强度和韧性,防止刀轴转速提高后刀轴弯曲变形,将原来的直径80毫米实心刀轴或直径114厘米空心刀轴,更换成直径160、180毫米的空心刀轴。2.减少动刀数量,加大动刀片为增大动刀的轴向间隙,便于在机壳上留出空间安装定刀,将原来的60片Y型动刀减至40片Y型动刀(有的将原来的60片Y型动刀减至41片,其中Y型弯刀28片,直刀13片),直刀略长于弯刀,并与弯刀交错排列,直刀切割阻力小,可少许入土。同时用9毫米厚、70毫米宽锰钢淬
1. Increase the speed of the cutter shaft, bold knife shaft Replace the straw or field of active or driven pulley, the knife shaft speed increased to 1800 rev / min, so that the movable blade to produce greater kinetic energy. In order to increase the strength and toughness of the cutter shaft and prevent the cutter shaft from bending and bending after the rotation speed of the cutter shaft is increased, the original 80 mm diameter solid cutter shaft or 114 cm diameter hollow cutter shaft is replaced with a hollow cutter shaft with a diameter of 160,180 mm. 2. Reduce the number of knives, increase the moving blade To increase the axial clearance of the knives, easy to set aside space on the cabinet to install fixed knives, the original 60 Y-knife reduced to 40 Y-knife (Some of the original 60 Y-type knife reduced to 41, including Y-shaped knife 28, straight knife 13), straight knife slightly longer than the machete, and the machete staggered arrangement, straight knife cutting resistance is small , Can be a little buried. At the same time with 9 mm thick, 70 mm wide manganese steel quenching
