1.力调节杠杆的支承弹簧太松支承弹簧的作用是使力调节拨叉杆的支点在调节杆上定位,如将力调节手柄向上扳动过猛,拨叉就会压缩弹簧,使整个杠杆前移,起一定的缓冲作用,以防止杠杆损坏,但弹簧的压紧度确定了力调节拨叉杆的支点位置。当弹簧太松时,力调节拨叉杆的支点过于靠后,欲使控制阀回到中间位置。力调节弹簧所需的压缩量比较小,所以当农具入土遇到不大的阻力后,控制阀便被推回到“中立”位置,从而限制了农具的最大耕深。排除方法:应适当拧紧力调节杆上的调整螺母,使拨叉杆的支点适当前移。
1. Force adjustment lever support spring is too loose The role of the support spring is to force the adjustment fork shaft fulcrum positioning on the adjustment rod, such as the force adjustment handle upwards move too fast, the fork will compress the spring, so that the entire lever Move forward, play a role in the buffer to prevent damage to the lever, but the compression of the spring to determine the force adjustment lever fulcrum position. When the spring is too loose, the force adjustment fork lever fulcrum too far behind, to make the control valve back to the middle position. The amount of compression required by the force-regulating spring is relatively small, so that the control valve is pushed back to the “neutral” position when the implement encounters little resistance to the soil, limiting the maximum depth of the implement. Remedy: Proper tightening force adjustment lever should be adjusted on the lever, so that the fulcrum lever fork forward appropriate.
