After the test is completed, the electric push rod (7513) is controlled to drive the moving plate (7511) to move, and the moving plate (7511) drives the top plate (751) and the gear member (754) to move, so that the placement plate (756) rotates, so that the concrete test block and the gravel are quickly discharged under the action of gravity; S3. When the test block is discharged, the push plate (7514) pushes the concrete test block to move so that the test block is discharged quickly, and the pressure plates (765) on both sides press the test block downward during testing.
