The invention provides a structural improvement of a peanut harvester, which is mainly composed of a control unit, a conveying unit, a loosening unit and a holding unit. With this innovative and unique design, the structural improvement of the peanut harvester in the invention uses these holding units to hold loose soil in the process of moving the peanut plant toward the conveyor belt through the pull-out belt of the return belt. And the fallen peanut plants enable the peanut plants to enter the conveyor belt smoothly, thereby enhancing the recovery factor.本創作係提供一種花生採收機之結構改良,主要係藉由一控制單元、一輸送單元、一鬆土單元及一扶取單元所相對構組而成;藉此創新獨特設計,使本創作花生採收機之結構改良藉由該等迴送帶拔帶花生植株朝該輸送帶行進的過程中,以該等扶取單元扶取鬆動土壤及其所垂倒的花生植株,使花生植株能順利地進入該輸送帶,進而提升採收率者。
