Description

Mining hammer convenient to use is surveyed in mining Technical Field The utility model belongs to the technical field of mining and surveying, and particularly relates to a mining hammer convenient to use in mining and surveying. Background Geological hammers (also known as mining hammers) are tools commonly used in mineral exploration, the hammerhead of which is usually designed as a dual-function structure with one end in the shape of a flat chisel and the other end in the shape of a square hammer face—square heads are used for breaking hard rock, and flat heads are used for precisely chiseling rock stratum cracks to separate ore samples; Currently, the conventional mining hammer generally adopts a hammer head and handle integrated structure, and has obvious limitation in actual use, when the hammer head is damaged due to high-frequency knocking or the hammer head with specific specification is required to be replaced by adapting to different mineral aggregate characteristics, an operator has to replace the whole hammer head and handle assembly integrally, or needs to additionally carry a plurality of mining hammers provided with different hammer heads, so that the operation cost and the physical burden carried by tools are increased, and the investigation efficiency is more likely to be influenced because the optimal tools cannot be adapted in time. Disclosure of utility model In view of the above, the utility model provides a mining hammer convenient for mining and surveying, which can realize quick disassembly and replacement by a quick disassembly mechanism, can quickly replace hammerheads according to mineral aggregates of different materials, can lock the replaced hammerheads, prevents loosening in the use process, ensures safety, does not need to carry a plurality of mining hammers, and reduces the operation cost and the physical burden carried by tools. In order to solve the technical problems, the utility model provides a mining hammer convenient for mining and surveying, which comprises a handle and a hammer head connected to the upper end of the handle in a threaded manner, wherein a quick-dismantling mechanism is arranged between the hammer head and the handle and comprises a dovetail groove arranged at the upper end of an extrados surface of the handle, a limiting block is connected in a sliding manner in the dovetail groove, a limiting slot movably connected with the limiting block is arranged at the lower end of the hammer head, a spring is arranged between the lower end of the limiting block and the bottom of the dovetail groove where the limiting block is positioned, so that quick dismantling and replacement are realized, the hammer head can be quickly replaced according to mineral materials of different materials, and meanwhile, the replaced hammer head can be locked, looseness in the use process is prevented, the safety is ensured, the whole length of the mining hammer can be adjusted, the knocking strength of the mining hammer is enhanced, the labor force of operators is lightened, and the labor intensity of users is remarkably reduced. The extension assembly comprises an extension rod which is connected with the lower end of the handle in a sliding way, namely the length of the handle is prolonged. The extension assembly further comprises a plurality of pressing plates arranged at the upper end of the extension rod, the upper end of the outer cambered surface of the extension rod is in threaded connection with a threaded sleeve, and the upper end of an inner cavity of the threaded sleeve is in movable contact with the outer parts of the plurality of pressing plates, so that the purpose of preliminary locking is achieved.
