Description

Technical Field

[0001] The utility model relates to the technical field of alloy bodies, in particular to a self-rotating spherical and annular hard alloy equipment support seat. Background Art

[0002] The cutting system and wear-resistant materials used in underground mining equipment are used to improve the wear resistance of products during the excavation of coal walls, rock walls and other materials. The main mining equipment includes coal mining machine drums, anchor digging machine drums, tunneling machine cutting heads, etc. The cutting system mainly includes pick-type picks, tooth seats, tooth sleeves and knife-type picks, tooth seats; wear-resistant materials include composite wear-resistant plates, composite wear-resistant blocks, crushed alloy wear-resistant blocks, alloy column wear-resistant blocks, etc. The knife-type picks and tooth seats of the cutting system cannot rotate or unload force, resulting in a large cutting resistance for the knife-type picks. It is very easy to break picks when cutting semi-coal and rock working faces ≥F5. The pick-type picks, tooth sleeves, and tooth seats of the cutting system can rotate, which can unload part of the resistance, and the materials on the cutting working face can generally reach a hardness of ≤F10. Wear-resistant materials are generally welded to easily worn locations on equipment or fixed with bolts. However, when the material is highly abrasive, the wear-resistant materials cannot move or rotate, and cannot unload force, resulting in more severe erosion and wear. Even if carbide wear-resistant materials are used, the wear resistance needs to be further upgraded and improved. Utility Model Content
