[0006] Furthermore, a grader control console is installed on the inner side of the cab body, and tempered glass screens are installed on adjacent sides of the cab columns.

[0007] Furthermore, the triangular connecting members are symmetrically screwed on the upper and lower surfaces of the cab top plate and the cab bottom plate, and mounting holes are provided on the surfaces of the triangular connecting members.

[0008] Furthermore, a mounting seat is welded to the lower surface of the cab floor, and the upper and lower end surfaces of the cab columns are respectively welded to the cab top plate and the cab floor.

[0009] Furthermore, the cab top plate, cab bottom plate, cab pillars, solid wooden pillars, and reinforcing ribs constitute the skeleton structure of the cab body.

[0010] Furthermore, the outer ends of the solid wooden columns are respectively embedded in the surface grooves of the cab top plate and the cab bottom plate, and fixing plates are welded to the upper and lower ends of the reinforcing ribs.

[0011] Furthermore, the cab pillars, solid wooden pillars and reinforcing ribs constitute a composite longitudinal support structure of the cab body.

[0012] The beneficial effect of the utility model is that the reinforced skeleton structure of the grader cab of the utility model utilizes the cab top plate, cab bottom plate, cab pillars, solid wooden pillars and reinforcing ribs inside the pillars to form the grader cab skeleton structure, and the solid wooden pillars and reinforcing ribs compositely connected inside the cab pillars can effectively resist the vibration impact generated when the grader is running, and at the same time strengthen the bearing capacity of the cab pillars, avoid deformation and bending of the hollow cab pillars, enhance the supporting strength and seismic resistance of the grader cab skeleton structure, and improve the skeleton strength of the grader cab.
