The dig-pull combined peanut harvester is mainly composed of a Vine detaching device, a Clamp chain, a Digging shovel and other components. Ensure the orderliness, neatness and smoothness of peanut raising and conveying operations. Vine detaching device advantage: 1.1 Strong and durable, it will not bend and deform when encountering hard soil and rocks; 1.2 The sharp mouth design, the separation is complete, and the peanut seedlings are not clamped; 1.3 The installation height and angle are adjustable, and the applicability is strong. (It can be adjusted according to the terrain, soil texture, and plant status.) Clamp chain advantage: 2.1 The design of the inclination angle of the clamping chain, the effect of raising seedlings is good, and the soil is clean; 2.2 It adopts a large opening design, and the closing time is short; 2.3 The height of the clamping point from the ground is small, and the adaptability of harvesting low crops is better. 2.4 When the forward speed is 1m/s, the clamping chain speed is 1.2m/s, the absolute clamping speed is 0.7m/s, α2+β2=92°, the vines always keep upward, and the positive extraction operation is realized.
