摘要： In order to improve the working performance of half-feed picking device, the components' collocation relationship and picking process were studied. The composition and working principle of picking device were introduced. The configuration relationships in between the components were studied. These were analyzed on the motion characteristics and hitting force of the blade, and the influences factors and rules of the effecting picking frequency. The analysis results shown: the configuration mode of the roller and clamping conveyor chain adopt the oblique configuration, and picking roller adopts gradually tight angle and differential phase configuration mode, which can effectively increase picking space, avoid missing picking, reduced the damage rates and power consumption. These factors were comprehensive influences to the picking performance of the roller rotational speed n, picking roller length Lz, the angle between roller d, roller diameter D and clamping conveyor speed v. The greater the roller rotating speed is, the stronger the blade hitting and combbrush role is, the greater the influence of the clamping conveyor chain speed is, the higher the picking net rate is, but the greater the damage rate of pod is and the higher the impurity rate is; with the increase of the roller turning angle, the hitting force is reduced, comb-brush role is enhanced, the picking net rate and damage rate are decreased, the influence of the clamping conveyor chain speed is decreased too; the bigger the level deflection angle of the picking roller is, the greater the axial hitting force is, the smaller the radial hitting force is, and the greater the influence of the clamping conveyor chain speed to picking quality is. When the Lz decreased and d increased, the picking time of the peanut region will shorten, it directly reduces the picking frequency, and then the picking quality has affected. The study provides a theoretical basis and technical reference for research and development of the half-feed peanut picking device.
