Shandong rock mine drilling tools co., LTD

H22mm cone connection drill rod is currently one of the largest output drill products in China, and it is also a large amount of rock drill used in domestic underground mines and traffic engineering construction projects. In the process of rock drilling, one cone connection drill rod can be equipped with multiple drill heads to drill blastholes with different bore diameters; the drill rods will not be scrapped after the drill heads are worn, and it has simple repair and low price; Has the characteristics of low consumption costs. It is currently the most used rock drilling tool product by domestic construction enterprises.

Drill bit drilling directly into rock is the most vulnerable part of drill bit.According to the rock drilling alloy shape bit used, it can be divided into the following types: flake bit (mainly including one word bit, three edge bit, cross bit, X bit) and column tooth bit.

Since the successful development of the first pneumatic rock drill in 1844 and its trial use in tunnel engineering, the rock drill has now reached nearly 160

Full hydraulic rock drilling rig is a new type of mechanized and highly automated rock drilling equipment that has emerged with the development of industrialization technology.

The newly purchased rock drilling machine is coated with anti-rust grease with large viscosity. It must be disassembled clearly before use. When reinstalling, the moving parts must be lubricated. After installation, connect the rock drill to the gas pipeline and run it in a small wind to check whether it is operating normally. Inject lubricating oil to the automatic lubricator. The common lubricating oil is 20 #, 30 #, 40 # engine oil. Containers filled with lubricating oil should be clean and covered to prevent rock dust and dirt from entering the injector.

The physical and mechanical properties of different rocks vary widely, and the correct choice of hard alloy for rock drilling must consider rock drilling methods, working parameters of rock drilling equipment, and rock properties.
