Working principle of hydraulic auger

[DIG-DOG]

A hydraulic auger is a screw-blade drilling machine that is mounted on a hydraulic excavator or slip loader and other models with a hydraulic system. The main engine supplies the hydraulic oil through the hydraulic motor and the gearbox in the drive head. For other operations, power is output to the lower end to connect to the drill pipe. The lower end of the drill pipe is welded with spiral scroll blades and special drill bits that spiral down into the soil layer to form a circular hole. Because the drill pipe is a spiral blade, the drilling method is a forward and backward vortex, so it is called auger drilling.

The hydraulic power of the rig is provided by the hydraulic excavator engine, which belongs to the front-end equipment of the excavator, also known as the excavator attachment. The hydraulic auger kit includes the main frame connection frame (single shaft, double shaft anti-swing, double shaft anti-swing), hydraulic drive head, mounting connector, auger rod, spiral blade, auxiliary teeth and center drill. The main engine connection frame is equipped with slide rails and balancing rods to enable the dropper rig to work quickly in multiple directions and ensure the verticality of the drilling hole. It flexibly coordinates work in contact with the surface and protects the drill pipe. It can be seen that the hydraulic auger can effectively improve the work efficiency.

The up and down movement of the drill pipe is realized by driving the gearbox of different types of driving devices, which is more conducive to downward force and fast drilling; The drill pipe is a spiral bladed drill pipe along which soil can be returned to the surface during drilling. Make the hole size clear and accurate.

The auger has the characteristics of high precision, low noise, low wear and long service life.
