After installing the DTH drill pipe, the power frequency and the pointer on the frequency switch in the control box should show the same ratio. If they are different, a frequency conversion switch should be used for conversion. The drill rod is installed on the drill rig. The placement of the drilling rig should be stable and firm, and the tappet should be adjusted by automatic fine-tuning or steel hammer to maintain its vertical state. Before starting the DTH drill pipe operation, the joystick should be adjusted to a neutral position. In the process of using the drill pipe, if you find that the drill-down limit alarm signal has been turned on, you must stop drilling in time, raise the drill pipe to a certain height, wait until the alarm signal is eliminated, and then you can continue drilling. Rod work. During the operation, when the rotation direction of the DTH drill pipe needs to be changed, the operation must be continued after the drill pipe stops safely.

　　When drilling the drill pipe, do not clean the dirt on the drill by hand. If you find that the strong bolts are loose, you also need to stop the operation of the DTH drill pipe immediately and continue the operation after tightening. After using the drill pipe, the DTH drill pipe and drill bit must be lifted from the hole, and the dirt on the drill pipe and spiral blade must be removed, and then the drill bit can be pressed to the ground. After braking this position, the joystick will be placed in the neutral position and the operating power will be disconnected.

　　With the development of mechanical alloying, rapid solidification technology has been developed rapidly. Due to the rapid development of geological drill pipes, the enhancement of fine crystals is very important. Deformation heat treatment can enhance the density of geological drill pipes and make them evenly distributed. Geological drill pipes can also be strengthened by fine grain strengthening and deformation.
