The XY-200 (YJ) drilling rig is designed to combine the main functions and features of small drilling rigs such as XY-1, XY-1B, XY-1A, which are currently popular in the market. The XY-1 hydraulic automatic feeding, XY-1B large modulus gear transmission system, and XY-1A wide range speed and large torque lightweight rotary drilling rig have added displacement function on the basis of the XY-200 drilling rig. ▶ This drilling rig is suitable for engineering geological surveys of buildings such as industrial and civil construction, railways, hydropower, transportation, bridges, and dam foundations; Geological core drilling and physical exploration; Drilling of small grouting holes, geothermal holes, blasting holes, and various concrete inspection holes; Small water well drilling, small foundation pile hole. ▶ In order to make the applicability of this machine more extensive and meet the needs of different users, the standard XY-200A drilling rig (without relocation or water pump function), the XY-200A-1 drilling rig with added water pump (without relocation), and the XY-200A-2 drilling rig with relocation and water pump function have been launched. The drilling rig and diesel engine are installed on the same base. The drilling depth can reach 200 meters. ▶ Users can choose the appropriate drilling rig model based on whether it comes with a belly mud pump and whether it requires relocation functionality. Drilling rig features: (1) It has an automatic hydraulic feeding mechanism, which improves drilling efficiency and reduces the physical labor intensity of workers. (2) Using a ball card clamping mechanism instead of a chuck, and equipped with a clamping positioning mechanism to perform non-stop rod tilting. (3) Equipped with a bottom pressure gauge to indicate pressure, making it easy to grasp the situation inside the hole. (4) The handle is centralized and easy to operate. (5) Compact structure, both drilling rig and power machine are installed .....
