一、液压系统主要结构方 案选择 1.耕深调节方法: 采用力调节和位调节两种调节方法。力调节主要用于犁耕作业,位调节主要用于割晒、堆垛等作业。实践证明,耕地时采用力调节法控制耕深,可使拖拉机工作负荷均匀,并可利用农具的重量和前轮的减载增加驱动轮的附着 First, the hydraulic structure of the main program options 1. Tillage adjustment method: the use of force adjustment and bit adjustment of two adjustment methods. Force adjustment is mainly used for plowing operations, bit adjustment is mainly used for cutting sun, stacking and other operations. Practice has proved that the use of force adjustment method to control tillage farming arable land, the tractor can work load evenly, and can use the weight of farm tools and the front wheel to reduce the load to increase the attachment of the drive wheel
