To improve the possessing quality of screw conveyor in agriculture, a rapid measurement method for possessing quality of the agricultural screw conveyor is proposed, and a rapid measurement device is developed. Measurement for processing quality of three main parameters is achieved, which are the shaft axial run-out, the screw blade axial run-out, and the screw blade pitch. The screw conveyor commonly used in the grain combine harvester was measured by the developed device. The test results show that: for the shaft axial run-out, the relative error is 1.47%, and the absolute error is 0.019 mm; for the screw blade axial run-out, the relative error is 2.31%, and the absolute error is 0.038 mm; for the screw blade pitch, the relative error is 1.89%, and the absolute error is 0.066 mm. It has a positive influence on the improvement of processing quality of agricultural screw conveyor.
