Excavator hydraulic spiral drilling machine is a type of spiral blade drilling machine, which is installed on a hydraulic excavator or slide. It uses hydraulic oil supplied by the main engine to operate through the drive head, gearbox, etc., and the power output is sent to the lower end. The lower end of the drill rod is welded with spiral vortex blades and special equipment, and the spiral drills downward into the soil layer to form a circular hole. Because its drill rod is a spiral blade and the drilling method is a vortex advance and retreat, it is called a spiral drilling rig.
The hydraulic power of the drilling rig is provided by the hydraulic excavator engine, which belongs to the front-end device of the excavator and is also known as the excavator auxiliary equipment. The hydraulic spiral drilling rig kit includes a main engine quick connector, hydraulic drive head, square installation chain, spiral drill rod, spiral blade, easy to install gear seat, auxiliary gear group, and main drilling gear. The host quick connector is equipped with a slide and a balance bar, which can enable the sagging drilling rig to work quickly in multiple directions and ensure the verticality of the drilling hole. It can flexibly coordinate and operate in contact with the ground while also protecting the drill rod.
This small hydraulic screw drill is simple and fast in installation, light in body, few restrictions on power host, and cheap in rent (ordinary small excavators can be used as its power host, unlike large pile drills, which must use special machines.) So it has been widely used by countrymen in projects of different sizes in just a few years since it was introduced from abroad.
It can be seen that hydraulic spiral drilling machines can effectively improve operational efficiency. The up and down movement of the drilling rig drill rod is achieved by driving the gearbox through different types of driving devices, which is more conducive to rapid drilling with downward force; The drill rod is a spiral blade drill rod, and the soil material can return to the ground along the blades during drilling. Make the pore size clear and accurate.
