According to the engineering machinery seat with the switchable damping assemblies, the spiral springs and the cylindrical dampers are connected in parallel to form the seat damping assemblies, the two different damping assemblies are installed on the same rotating disc, a driver can adjust the angles of the two rotating discs through the handle to switch the damping assemblies which play a role according to the weight of the driver and the working conditions, and therefore the damping assemblies can be switched. The bearing capacity and the vibration reduction characteristic of the seat are changed, the vibration comfort of engineering machinery is improved, and the seat has the advantages of being low in cost and suitable for drivers with different weights and working conditions. Meanwhile, a rotating disc limiting mechanism and a handle fixing frame are arranged on the fork arm lower plate, only when the seat is free of bearing and the spiral spring is free of pre-tightening force, the rotating disc can be adjusted to switch the vibration reduction assembly, and misoperation can be effectively avoided.

    本发明提供一种减振组件可切换式工程机械座椅,螺旋弹簧和筒式减振器并联构成座椅减振组件,两个不同的减振组件安装在同一旋转盘上,驾驶员可根据自身体重和作业工况,通过手柄调节两个旋转盘角度切换起作用的减振组件,改变座椅承载能力和减振特性,提升工程机械的振动舒适性,该座椅具有成本低且适用于不同体重驾驶员和作业工况的特点。同时,在叉臂下板上设置了旋转盘限位机构和手柄固定架,只有座椅无承载且螺旋弹簧无预紧力时,才可调节旋转盘进行减振组件的切换,可有效避免误操作的发生。
