The mass spectra, root mean square (r.m.s.) radii and radial density distributions of and
baryons are firstly analyzed in the present work. The calculations are carried out in the frame work of relativized quark model, where the baryon is regarded as a real three-quark system. Our results show that the excited energy of charmed-bottom triply baryons are always associated with heavier quark. This means the lowest state of
baryon is dominated by the
-mode, however, the dominant orbital excitation for
baryon is
-mode. In addition, the influence of configuration mixing on mass spectrum, which is induced by different angular momentum assignments, is also analyzed. It shows that energy of the lowest state will be further lowered by this mixing effect. According to this conclusion, we systematically analyze the mass spectra of the ground and excited states(

and

,

and
baryons. Finally, with the predicated mass spectra, the Regge trajectories of these heavy baryons in the (J,
) plane are constructed.
