KA－2M－300型钻机目前在我国地质勘探队使用得比较广泛,因为它具有很多优点:结构简单、拆卸、搬运方便、零件坚固、维修简便,虽然这种手把式给进钻机在操作方面比油压给进钻机费力,但仍有一定使用价值。目前这种钻机的传动方式绝大多数以柴油机作为动力,带动中间轴,中间轴上有三或四个皮带轮,分别带动钻机、泥浆泵、泥浆搅拌机及照明用发电机。这样的传动布置具有下列缺点:
The KA-2M-300 drilling rig is currently used extensively in our country’s geological exploration team because it has many advantages: simple structure, easy disassembly, easy handling, solid parts, and easy maintenance. Although this type of hand-operated drilling rig is in operation It is more laborious than hydraulic rigs, but it still has some use value. At present, most of the transmission methods of such drilling rigs are powered by diesel engines, which drive the intermediate shafts and three or four pulleys on the intermediate shafts to drive rigs, mud pumps, mud mixers and lighting generators. This drive layout has the following disadvantages:
