摘要
在手摇式果园轻简型挖穴机上安装直流电动机、传动机构、安全装置和电控装置,构成果园轻简型挖穴机电动助力系统。系统运行结果表明:空载时,挖穴机携带直径分别为30和20 cm的钻头上升和下降的平均速度与蓄电池功耗间的线性相关系数分别为0.790、0.910、0.927和0.865,线性度较高;携带大、小钻头实地挖穴时,助力系统能够以1.32或1.43 cm/s的速度提升挖穴机,提升钻头所需的启动电流没有明显差异。
The DC motor, transmission mechnism, safety unit and electric control unit installed in a hand-cranked orchard simple type earth auger formed the electric power assistance system of orchard simple type earth auger The system＇s performance showed： when the orchard simple type earth auger carried no load, when it was equipped with a drill bit with a diameter of 30 and 20 cm, the linearity coefficients between its average speed of rising and falling and the battery power consumption were 0.790, 0.910, 0.927 and 0.865, respectively, the linearity is high; when the orchard simple type earth auger was digging the earth after it was equipped with the same above mentioned drill bit, the electric power assistance system could raise the earth auger at speed of 1.32 or 1.43 cm/s, and there was no significant difference between the starting electrical current for the drill bit when it was digging and the starting electrical current for the drill bit when it was operating without digging.
