In recent years, with the continuous improvement of China's mining industrialization rate, mineral sizers have become rapidly popular due to their advantages of large processing capacity and regular appearance. Among them, detachable tooth head structure has been widely used in various mining production enterprises because of its low maintenance cost and high maintenance efficiency. High-speed steel as a high hardness, high heat resistance, high wear resistance of the material, its material properties are very suitable for the ore crushing process, more and more crusher manufacturers began to use high-speed steel to replace the traditional manganese steel crusher tooth head. However, the traditional integral high speed steel tooth head has certain defects, the high speed steel after heat treatment has high hardness but poor toughness, the root part of the tooth is easy to break under the strong impact condition of ore crushing, and the high speed steel material weldability is poor, can not be repaired by traditional welding methods, which leads to once the tooth head fracture can only be replaced, greatly increasing the cost of equipment. In order to solve the technical problems, a split high speed steel tooth for mineral sizers is provided. The purpose of providing a split high speed steel tooth for mineral sizers is to provide a split high speed steel tooth for mineral sizers. The tail of the tooth head (1) is provided with a ring boss (1-1), and the tail sleeve is spliced by the first tooth tail sleeve (4) and the second tooth tail sleeve (5), the splicing surface of the first tooth tail sleeve (4) and the second tooth tail sleeve (5) coincide with the shaft section of the tooth head (1), and the first tooth tail sleeve (4) is provided with a circular arc pin groove (4-1); The upper end face of the first tooth tail sleeve (4) and the second tooth tail sleeve (5) is provided with a connecting tooth head (1) slot: the first tooth tail sleeve (4) is provided with a cone pin hole (4-4) and a connecting hole (4-2) : The cone pin hole (4-4) is provided with a second tooth tail sleeve (5) : The cone pin hole (4-4) is located at the bottom of the card slot: The inner wall of the card groove is provided with a ring groove (4-3) matching with a ring head (1 1) : a first elastic cylindrical pin (2) is provided at the taper pin hole (4-4) : a second elastic cylindrical pin is provided at the connecting hole (4-2).
In order to further understand the content, characteristics and functions of the mineral sizers' teeth, the following embodiment is given and described in detail with the attached drawings: The technical solution is: A mineral sizers uses a split high-speed steel tooth head to separate the tooth head from the tail, specifically: The tail of the tooth head 1 is provided with a ring boss 1-1, and the tooth tail sleeve is spliced by the first tooth tail sleeve 4 and the second tooth tail sleeve 5. The splicing surface of the first tooth tail sleeve 4 and the second tooth tail sleeve 5 is overlapped with the shaft section of the tooth head 1. The first tooth tail sleeve 4 is provided with a circular pin groove 4-1: the upper end face of the first tooth tail sleeve 4 and the second tooth tail sleeve 5 is provided with a clamping groove with a connecting tooth head 1: The conical pin hole 4-4 and the connecting hole 4-2 are provided on the first tooth tail sleeve 4: To prevent sliding, the end face of the connecting hole 4-2 is semicircular in the present preferred embodiment. A taper pin hole is arranged on the second tooth tail sleeve 5: the taper pin hole 4-4 is located at the bottom of the card slot; The inner wall of the card groove is provided with an annular groove 4-3 matched with an annular convex table 1-1: a first elastic cylindrical pin 2 is arranged at the cone pin hole 4-4: a second elastic cylindrical pin is arranged at the connecting hole 4-2.
