日本长谷川清发明了一种直线型电动破碎机。现将该发明介绍如下。该机主要用于采石、破碎矿石及路面。过去,这些工作主要由以压缩空气为动力的风动破碎机来完成。由于风动破碎机的空气消耗量很大,必需使用大容量的空气压缩机,除了耗费大量的能源及资金外,在从一个作业现场迁移到另一个作业现场时也很费活 Japan Hasegawa clear invented a linear electric shredder. The present invention is as follows. This machine is mainly used for quarrying, crushing ore and pavement. In the past, these jobs were mainly done by compressed air-powered air-powered breakers. Due to the high air consumption of the aircrakers, it is necessary to use large-capacity air compressors that are not only labor-intensive and costly to migrate from one work site to another
