AI Technical Summary
When unloading the straw box of a traditional peanut harvester, the discharge height is insufficient, making it difficult to directly unload the peanut vines into the higher compartment of the straw collection vehicle. This increases labor intensity and reduces unloading efficiency, and also easily leads to problems such as material scattering and uneven accumulation.
Design a secondary lifting device for the hay box of a peanut harvester, comprising a fixed support and a movable support, equipped with a flipping and lifting mechanism, wherein the movable support is driven to move longitudinally and the flipping plate is rotated by a hydraulic cylinder to change the material discharge height.
This enabled the peanut vines to be unloaded smoothly from the grass collection vehicle, reducing labor intensity and improving unloading efficiency, while ensuring that the material was loaded evenly.
