自1976年3月新晃汞矿用新—Ⅰ型机械化作业线创造了平巷独头月掘进尺1056.8米的全国纪录后,有些同志曾先后提出新—Ⅰ型装载机在蟹爪前面加一对立爪有没有必要的问题。它有哪些优点?会出现什么问题? 我们在蟹爪前面加上一对立爪,经过较长时间的使用,证明有以下优点: 一、立爪能揽取整个巷道宽度的岩碴。两个立爪的正常工作位置,是对称地布置在与机器中心线的夹角约为60°的前方左右两侧(见附图)。它们不停地把蟹爪耙不到的、靠近巷道两侧帮的岩碴耙集到机头铲板的前面来。整个机器只需沿着巷道中线前进,一次进出,全部装完,因而不占用辅助时
Since the new mercury mine of Shin-Akihuang in March 1976 created a national record of 1056.8 meters of single-lane undercutter with a new-type mechanized operation line, some comrades have successively proposed that a new-type loader add a Opposing claws there is no necessary problem. What are its advantages? What problems will arise? In front of the crab claw plus a pair of claws, after a long period of use, proved to have the following advantages: First, the claw can take the width of the entire rock ballast. The normal operating positions of the two jaws are symmetrically arranged on the left and right sides of the front (see the figure) with an angle of about 60 ° to the centerline of the machine. They keep ramsaws that are not caught by the crabs and close to the sides of the roadway to the front of the noseboard. The entire machine just along the roadway center forward, once out, all finished Bahrain, which do not take up auxiliary
