Land leveller
The invention relates to a land leveller, and aims to solve the problem that bolt locking time is difficult to determine after posture adjustment of a lifting arm of an existing land leveller. According to the land leveller, a lifting arm locking control device comprises knob switches and limiting switches of N rotating gears, a stator and a rotor of each limiting switch are fixedly connected witha hinge support and a lifting arm respectively, and the closing position between each static contact and a corresponding movable contact corresponds to the coaxial alignment position of each limitinghole in a connecting rod and a plug pin in a one-to-one mode; and N static contacts of the knob switches are electrically connected with N static contacts of the limiting switches in a one-to-one correspondence manner, and an electromagnetic coil of an electromagnetic reversing valve is electrically connected with the movable contacts of the knob switches and the movable contacts of the limitingswitches respectively after being connected with a power supply in series. According to the land leveller, automatic hole aligning and locking can be achieved, damage accidents caused by misoperationare avoided, the man-machine performance and safety are improved, the operation efficiency is also improved, and the operation flexibility is improved.
本发明涉及平地机，为解决现有平地机提升臂姿态调整后插销锁紧时机难以确定的问题；提供一种平地机，其提升臂锁紧控制装置包括：N个旋转挡位的旋钮开关和限位开关，限位开关的定子和转子分别与铰接支座和提升臂固定连接且每个静触点与动触点之间的闭合位置与连杆上各限位孔与插销同轴对齐位置一一对应；旋钮开关的N个静触点与限位开关的N个静触点一一对应电连接，电磁换向阀的电磁线圈和电源串联后分别与所述旋钮开关的动触点和限位开关的动触点电连接。本发明能够自动对孔锁紧，避免误操作产生损害事故，增加了人机性、安全性，也提高了操作效率，增加操作灵活性。
