Small borehole drilling machine is a kind of small drilling equipment suitable for rural well drilling, self-built water source and geological exploration. With its small size, easy transportation and simple operation, it is especially suitable for areas with complicated terrain and limited space. Compared with traditional large-scale equipment, this kind of portable well drilling rig is not only economical and practical, but also has good drilling ability in sandy soil, clay and pebble mixed layer, which is a widely used solution in rural areas and small-scale projects at present.
Multi-layer adaptability of Small Borehole Drilling Machine
drilling performance in sand, clay and pebble layers
In sandy soil layer, small borehole drilling machine is usually used with auger bit, which can be drilled down quickly and not easy to collapse the hole with its lightweight structure;
In clay layers, due to the strong adhesion of the soil, we recommend the use of auger drilling tools with slag removal function and intermittent hole cleaning to avoid jamming;
As for the pebble layer, the alloy tooth hob bit of YG equipment performs particularly well, capable of breaking gravel within 10cm in diameter and stabilizing the drilling efficiency.
How to Determine Whether the Drill Bit Needs to Be Replaced?
According to our experience, during the drilling process, observing the color and particle changes of the rock chips is one of the key ways to determine whether to change the drill bit. For example, after entering the pebble layer, there will be obvious quartz grains or pebble particles in the rock chips, at this time, if you find that the drilling speed has dropped significantly, you should change to a suitable hobbing tooth or alloy bit in time. In addition, the operator also needs to pay attention to the changes in the vibration amplitude of the machine, such as machine operation suddenly becomes unstable, may also suggest that the drill bit is seriously worn.
Among portable water extraction solutions, YG’s small borehole drilling machines have won wide recognition for their stable performance and multi-layer adaptability. Whether it is used for home-built wells, rural drinking water projects, or field sampling operations, this portable well drilling rig is the ideal choice.
