栽树挖穴,是山坡地上栽培果树和种植树木时的繁重劳动之一。为了解决这个问题,相继研制出多种类型的带有螺旋钻和整体犁铲的挖穴机。但是,在土壤很坚硬的边埂地带和斜坡地上作业,他们的工作部件都不易入土,犁铲的入土角度和钻机的转速也不能调整。阿塞拜疆农机化电气化科研所研制出了工作部件可调式挖穴机,它主要由钻轴6和叶片7组成(图1)。在轴的末端有固定板8,借助 Digging trees, digging, hillside cultivation of fruit trees and planting trees one of the arduous work. In order to solve this problem, we have developed many types of digging machines with augers and integral plowshares. However, when working on hard-edged fields and slopes, the working parts of them are not easy to dig in and the plowing angle and drilling speed can not be adjusted. Azerbaijan Agricultural Mechanization Electrification Research Institute has developed a working unit adjustable digging machine, which consists of the main shaft 6 and the blade 7 (Figure 1). At the end of the shaft with a fixed plate 8, with
