Abstract
Root-tuber crops are buried under the ground, thus, the mechanization harvest should apply digging method. However, the row-aligning angle of the shovel can directly influence the digging effect. Therefore, a set of auto-aligning technological equipments were designed to solve this problem and achieve aligned digging. This paper mainly analyzes the design of above mentioned equipments as below: A right-left angular displacement sensor is added in the front part to achieve auto-induction and signal transformation of the digging angel through comparison of the pressure angle. The adjustment of the control equipment can be achieved by the adjustment of signal when it goes through magnetic exchange valve. And with the help of cross slide way, the digging harvest machine can modulate the shovel timely and efficiently. Experiments demonstrated that such auto-row-aligning equipment can improve the digging effect.
