Patent Name Patent No. Patentee Patent Type Authorization Announcement Day

Polycrystalline diamond composite pick ZL201220735269.0 Sifangda Utility model June 12, 2013

The fixing of the tooth head and the tooth tip of the "polycrystalline diamond composite pick" is fixed by the protrusion and the corresponding groove, and then the welding is fixed. This fixing method increases the contact area between the tooth head and the tooth tip, and improves the contact area. The welding strength of the alloy tooth head and the tooth tip avoids the tip of the tooth falling off when the rock formation is dug, which improves the service life of the pick.

The acquisition of the above patents will not have a major impact on the company's production and operation, but it will help protect the company's intellectual property rights, form a continuous innovation mechanism, and enhance the company's core competitiveness. Special announcement.
