Design of Picking Roller for Corn Harvester Picking Machine and Selection of Hydraulic Motor

Abstract

In the actual application process, the corn harvester has problems such as high loss rate of fruit and energy waste. This article analyzes the corn picking device, the reason for the high loss rate is found, and a new picking roller is designed. Through the calculation of the force and torque of the picking roller and the chain during the harvesting process of the corn harvester, the power required for the picking device is obtained, and the hydraulic motor model required for the picking device is further obtained. Through design and analysis, we determined the optimum speed of picking roller in corn picking process: 836r/min, picking roll inclination angle: 35°, and picking roll radial size: 75mm. The article determines that the hydraulic motor model is the American white cycloidal motor WS80.
