  DTH Bit can also be called a soil drill. When we use the soil drill, we want to know what the working principle of the soil drill is? In fact, the principle of the earth-boring machine is very simple. The following editor brings you an analysis of the principle of the earth-boring machine. Let’s take a look!

   

   

  What is the working principle of the earth drilling machine? The small hydraulic auger is a spiral blade drilling machine. It is installed on a hydraulic excavator or a skid steer loader. The hydraulic oil supplied by the main engine is output to the lower end through the hydraulic motor in the drive head and the reduction box. Connect the drill pipe, the lower end of the drill pipe is welded with a spiral vortex blade and a special drill bit, which spirally drill down into the soil layer to form a circular hole. Because the drill rod is a spiral blade, the drilling method is a vortex forward and backward, so it is called auger drill. The hydraulic power of the drilling rig is provided by the hydraulic excavator engine, which belongs to the front-end device of the excavator, also known as excavator auxiliary equipment.

   

   

  The hydraulic auger kit includes the main machine quick linker, hydraulic drive head, square mounting link head, spiral drill rod, spiral blade, easy-to-install gear seat, auxiliary group gear, and main drill gear. There are slideways and balance rods on the main machine's quick link, which can make the drooping rig work quickly in multiple directions and ensure the verticality of the drilling. It can flexibly coordinate with the ground contact operation and protect the drill pipe. This small hydraulic auger drill is simple and fast to install, light in body, less restrictive on the power host, and cheap to rent (ordinary small excavators can be used as its power host, unlike large pile drilling rigs that must use special machines.) So from abroad In just a few years after its introduction, it has been widely used by Chinese people in projects of different sizes. It can be seen that DTH Hammer can effectively improve work efficiency. The up and down movement of the drill rod of the drilling rig is realized by driving the gearbox of different types of driving devices, which is more conducive to downward force and rapid drilling; the drill rod is a spiral blade drill rod, and the soil material can be returned to the ground along the blade during drilling. superior. Make the hole size clear and accurate.
