叉式挖掘部件是一种出现较早的挖掘器,经过多年的发展其形式有许多种。单柱双叉式挖掘部件是根据西北地区甜菜收获时土地干硬、杂草丛生和目前播种作业水平不高行距偏差较大,以及考虑到我国甜菜收获的现状,即可以先切缨后挖掘,又可以带缨挖掘后人工切缨而设计的。本文从理论和实践两方面对它进行探讨,试图证明有其生命力,引起人们对叉式挖掘部件应有的认识。
Fork excavation is an early emergence of the excavator, after years of development there are many forms of its form. The single-column double-fork excavation part is based on the dry and hard land, the overgrowth of overgrowth of weeds and the low level spacing of the current sowing operations at the time of beet harvesting in the northwest region, and taking into account the present state of beet harvest in our country, They can also be designed to carry artificial cuts after mining. This article discusses it both theoretically and practically in an attempt to prove its vitality and arouse people’s understanding of fork excavation components.
