Description

Technical Field

[0001] This utility model relates to the field of hammerhead technology, and in particular to a high wear-resistant martensitic steel hammerhead for mining accessories. Background Technology

[0002] Mining hammers are key components used in mining machinery, primarily for crushing and pulverizing materials. Hammers are typically mounted on the rotor of a crusher, striking and compressing materials through high-speed rotation to achieve crushing. Hammers are wear parts, therefore their material and manufacturing process significantly impact their durability and performance. There are various types of mining hammers, including: hammer crusher hammers, used for crushing various ores and rocks such as limestone and granite; and crushing shaft assembly hammers, mainly used in the middle of scraper conveyors to crush large coal blocks, preventing excessive pressure on subsequent equipment when large coal pieces fall. However, hammers are currently among the most easily worn parts. During operation, the irregular shape of the stone causes uneven impact forces on the hammers, resulting in uneven wear. Without replacement, wear reduces production efficiency and increases crushing time; however, replacement leads to material waste. Utility Model Content

The mounting block 2 is made of martensitic steel. A butt block 3 is fixedly mounted on the rear surface of the mounting block 2. A butt groove 301 is opened in the middle of the front surface of the hammerhead body 1, and the butt block 3 is inserted into the butt groove 301. A rectangular insert plate 4 is fixedly mounted on the rear surface of the mounting block 2 near the outer end. A rectangular slot 401 is opened on the front surface of the hammerhead body 1 near both ends, and the rectangular insert plate 4 is inserted into the rectangular slot 401. A connecting structure 5 is provided inside the hammerhead body 1.

[0020] The connecting structure 5 includes a circular groove 501, a rotating block 502, a rotating rod 503, a first bearing 504, a rectangular groove 505, a rectangular slide 506, a rectangular slider 507, a first groove 508, a rectangular locking block 509, a first bevel gear 510, a second bevel gear 511, a threaded rod 512, a second bearing 513, a connecting rod 514, and a rectangular locking groove 515; the upper surface of the hammer body 1 has a circular groove 501, the rear end of the rectangular insert plate 4 has a rectangular locking groove 515, and the interior of the hammer body 1 has a rectangular groove 515. 05.
