The invention relates to the technical field of cleaning machines, in particular to an overturning centrifugal vegetable cleaning machine which comprises a shell and a cleaning cylinder, the shell is connected with a feeding hopper, the feeding hopper is connected with a feeding channel, a plurality of liquid leakage holes are formed in the cleaning cylinder, and a limiting ring and an annular rack are arranged on the outer wall of the cleaning cylinder. A limiting wheel, a first-stage motor and a receiving hopper are installed in the shell, a support is installed on the inner top face of the shell, and the support is connected with a top plate. When vegetables are cleaned, the vegetables are firstly added into the cleaning cylinder, then a first-stage motor is started to drive a first-stage gear to rotate, the cleaning cylinder is driven to rotate through an annular rack, so that the vegetables in the cleaning cylinder are turned over, a second-stage motor is started to drive a second-stage gear to rotate, and the second-stage gear drives a rotating rod to rotate through a chain; and the brush cylinder is rotated, the brush cylinder scrubs the surfaces of the vegetables, meanwhile, the high-pressure nozzle flushes the vegetables, and the vegetable cleaning effect can be greatly improved.
