The utility model discloses an excavator bucket rod valve element assembly with a regeneration cut-off function. The valve comprises a bucket rod valve core and a valve body, the bucket rod valve element is of a hollow structure. A plurality of radial small holes are formed in the bucket rod valve core; the radial small holes are connected with a rod cavity and a rodless cavity of the bucket rod; a bucket rod valve core one-way valve is arranged on the left side of the bucket rod valve core; the flowing direction is controlled only from a rod cavity to a rodless cavity through the bucket rod valve core one-way valve; compared with the prior art, according to the technical scheme, a regeneration function is adopted under the condition that small excavation force is needed, large flow is used for improving efficiency, energy conservation is achieved, and under the condition that large excavation force is needed, the regeneration function is closed, oil return back pressure is reduced, and the excavation force i
