问题1在单斗挖掘机作业时,要根据作业高度和土质状况来调整切削角。请您指出其中哪一项是错误的?1)在挖掘高度低的情况下切削角大一些为好;2)在结实坚硬土质条件下,切削角小一些为好;3)平整土地或挖掘坡地时,切削角小一些为好;4)在松软土质情况下,切削角大一些为好;5)在挖掘高度高的情况下,切削角小一些为好。

Question 1 In the single bucket excavator operation, the cutting angle should be adjusted according to the working height and soil conditions. Please indicate which one of them is wrong. 1) It is better to have a larger cutting angle when the excavation height is low; 2) It is better to have a smaller cutting angle under solid and hard soil conditions; 3) Level the land or excavate the slope At the time, the smaller the cutting angle, the better; 4) in the case of soft soil, the larger the cutting angle is better; 5) in the case of high excavation height, the smaller the cutting angle is better.
