Cucumber grader

The utility model discloses a green cucumber grader and belongs to the technical field of separation equipment. Two sets of supporting mechanisms are arranged, a plurality of screening rollers are erected between the two sets of supporting mechanisms, and a first driving motor is used for driving a first transmission belt to rotate and driving a plurality of first driven belt wheels to rotate, so that rotation of the screening rollers is achieved, sorting of green cucumbers is achieved, manual grading is reduced, and the grading precision is improved; the screening rollers are divided into at least two groups, and the screening grooves in the screening rollers in the rear group are larger than those in the screening rollers in the front group, so that in the green cucumber screening process, green cucumbers with smaller diameters fall off from the smaller screening rollers in the screening grooves in the front side, and green cucumbers with larger diameters fall off from the larger screening rollers in the sc
