目前我們很多矿山所有的电耙,据了解一般都沒有很好的使用,这些設备的長期积压,給国家造成了一定程度上的浪費与損失。某矿在2公尺×1.8公尺小规格的坑道掘进中,一天进行6次循环,如用人工出碴不但劳动强度太大,而且势將影响循环的时間。所用电耙是141瓩,耙斗机齿較硬,間距2公分。为了解决細碎碴石的耙裝問題,矿山又制作了与原扒斗規格大小彷彿,只是
At present, we have a lot of mines all the electric rake, it is understood that generally not well used, the long-term backlog of these devices to the country caused a certain degree of waste and loss. A mine in 2 meters × 1.8 meters small tunnel excavation, a day for 6 cycles, such as manual labor not only labor intensity is too large, and the potential will affect the cycle time. Electric rake is 141 瓩, harrow bucket machine teeth hard, pitch 2 cm. In order to solve the problem of scraping stone crushing stone, mines and the production of the original bucket size specifications as if, but
