我厂倒废石采用自动翻车,矿车的来回运行也是自动;但以前计算倒出废石的车数却需每班设一个专人。在深入学习无产阶级专政理论的运动推动下,1975年6月广大工人提出要将人工记数改成自动计数,向党的生日献礼。在矿党委和厂党支部的领导下,组成了三结合技术革新小组,经过一个月的努力,研制成功矿车自动计数器。 矿车自动计数器使用近一年,性能良好,计数准确可靠。而且结构简单、制作容易、维护方便,特别是无须另接能源。其工作原理(见图),是利用被计数物件通过时的 I waste dumping plant with automatic rollovers, tubs running back and forth is automatic; but before the calculation of the number of cars poured out of waste rock need to set up a special class. Driven by the campaign of studying the theory of dictatorship of the proletariat, the majority of workers in June 1975 proposed that the manual count should be changed to automatic counting and the party’s birthday be sacrificed. Under the leadership of the coal mine party committee and the factory party branch, a three-pronged technical innovation group was formed. After a month’s efforts, a successful automatic mine car counter was developed. Automatic car tub counter usage for nearly a year, good performance, accurate and reliable counting. And the structure is simple, easy to make, easy to maintain, especially without additional energy. The working principle (see figure), is the use of the object is counted when
