Abstract

The invention discloses an operating device of a skid-steering loader, comprising a handle mechanism, a connecting rod mechanism, a tilting mechanism, a double-piston pump and a main control valve body. The handle mechanism comprises a left handle and a right handle, a left bearing seat and a right bearing seat, a left support bracket and a right support bracket, the lower ends of the handles arerespectively and fixedly connected with the bearing seats, the bearing seats are respectively articulated with the upper ends of the support brackets; the connecting rod mechanism comprises a plurality of vertical connecting rods and a plurality of horizontal connecting rods, the upper ends of the vertical connecting rods are respectively articulated with the bearing seats, and the lower ends arerespectively articulated with the tilting mechanism; two ends of the tilting mechanism are respectively supported at the lower side of a floor of a driving cab of the loader, one ends of the plurality of vertical connecting rods are respectively articulated with the tilting mechanism, and the other ends are respectively articulated with a variable swash plate of the double-piston pump and a hydraulic valve plug of the main control valve body. The invention has the advantages of less parts, simple manufacturing, low cost, high reliability, light and comfortable operation, intensively arranged parts and components, convenient change and maintenance, and better meets the requirements on ergonomics.

Description

technical field [0001] The invention relates to a loader operating device, in particular to a mechanical operating device for controlling the action of a skid steer loader with both hands, and belongs to the technical field of engineering machinery. Background technique [0002] The walking and attachment actions of the skid steer loader are driven by full hydraulic pressure. The transmission sprocket is driven by the hydraulic motor on both sides of the whole machine, and the driving wheel is driven to rotate through the transmission chain. The skid steer loader is small in size, compact in structure, and has a small internal installation space. The loader has so many control points that it is impossible to use the steering wheel steering of ordinary wheel loaders or operate the independent hydraulic joystick in the cab. [0003] The existing operating mechanism of the skid steer loader is mainly divided into two-handed mechanical operation, one-handed hydraulic pilot opera...
