For the caused harvesting loss problem by inaccurate alignment of the semi-feeding peanut harvester, an automatic alignment system on the control core of the single chip microcomputer μPD78F0525 was designed. The system adopts a four-bar detection mechanism to transmit the offset to the controller through the sensor and to adjust the excavator in time. On this basis, a peanut automatic alignment test device is developed, which is composed of conveying platform, ridge ditch, hydraulic execution system, signal detection mechanism, signal processing and control system, etc. The influence effect of the main factors of the system is tested through the test bench. The results show: the reaction time increases with the increase of spring preload and deviation distance, gradually decreases and tends to remain unchanged with the increase of forward speed, and first decreases and then increases with the increase of hydraulic flow. The unqualified rate first decreases and then increases with the increase of spring preload, gradually increases with the increase of forward speed and deviation distance, and gradually decreases with the increase of hydraulic flow. The effectiveness and stability of the automatic alignment system can meet the operation requirements. It effectively solved the problem of automatic alignment of the semi-feeding peanut harvester and provided a technical reference for the research and development of the automatic alignment system for harvesting the fruits under the soil.
