| Abstract:In response to the needs of geological exploration and in-situ leaching mining hole construction in sandstone uranium mines， the HXY-1600 mechanical power head long stroke feed trailer drilling rig has been developed. The HXY-1600 trailer drilling rig is designed as a through type mechanical power head with a long stroke feeding structure that can be opened and closed. The core can be taken in one feeding， and a dual gear pump is selected as the hydraulic system power component. It is combined with multiple valves to achieve power head feeding， hydraulic chuck opening， etc； Select a 9-speed Fast gearbox， providing multiple output speeds； The trailer type drilling rig adopts a telescopic drilling tower， which is convenient for transportation and relocation. Using a drilling parameter display system， real-time recording of drilling parameters and automatic generation of drilling reports. In addition， safety protection functions such as drilling tower overload， hook load exceeding limit， and power head torque exceeding limit warning have been set up. This drilling rig is mainly used for the exploration of in-situ leached sandstone uranium deposits， and can be used for rope core drilling technology as well as in-situ leached mining hole drilling technology. The on-site engineering construction application shows that the HXY-1600 trailer drilling rig has a compact structure， reliable performance， strong adaptability to complex formations， safe and comfortable operation， and high drilling efficiency. |
