我厂过去大炉上料,一直是用人工,劳动强度大,条件差。为减轻劳动强度,提高生产率,于1973年制成单绳摇臂提升卸料机。经两年多的使用,效果良好。一、结构型式和动作原理卸料机的结构如图1,立柱2由顶针座1和滑动轴承6支承,起重臂5与立柱焊为一体。支架10与半圆形转盘9固定在立柱2上,起重臂的前端装有卸料架19,用两个拉簧将卸料架拉紧。料斗焊成方形,料门用合页连接, Our factory in the past furnace feeding, has always been artificial, labor-intensive, poor conditions. In order to reduce labor intensity, improve productivity, made in 1973 single rope rocker lifting unloader. After two years of use, the effect is good. First, the structure type and principle of action Unloading machine structure shown in Figure 1, the column 2 by the thimble seat 1 and bearing 6 bearings, jib 5 and column welding as a whole. The bracket 10 and the semicircular turntable 9 are fixed on the column 2, the front end of the boom is provided with a discharge rack 19, and the discharge rack is stretched by two tension springs. Hopper welded into a square, door hinge with the connection,
