Latest Patents

One of Tiejun Lin's latest patents is a "Wear-resistant and collision-resistant polycrystalline diamond compact (PDC) drill bit with rostriform teeth and plurality of blades." This invention features a novel design that includes an upper joint and a drill matrix. The PDC drill bit is engineered to break rocks using primary teeth through penetration-splitting and secondary teeth through shearing. This innovative design significantly reduces the torque required to break rocks. Additionally, the arrangement of the blades ensures balanced force distribution, minimizing abrasion loss of the teeth over time.

Another significant patent is the "Remote-controlled adjustable-speed screw drill for gas-drive hydraulic-motive during gas drilling." This invention incorporates a piston speed control system, motor assembly, cardan shaft assembly, and transmission shaft assembly. The system utilizes high-pressure gas to drive pistons, enabling high-speed movement that facilitates self-circulating motion within the driving screw. This design enhances the efficiency of gas drilling operations.
