Description

Technical Field

[0001] This utility model belongs to the field of mining exploration technology, and specifically relates to a mining hammer that is easy to use in mining exploration. Background Technology

[0002] Geological hammers (also known as mining hammers) are commonly used tools in mineral exploration. Their hammerheads are usually designed as a dual-function structure with one end being a flat chisel shape and the other end being a square hammerhead. The square head is used to break hard rocks, while the flat head is used to precisely chisel into rock strata fissures to separate ore samples.

[0003] Currently, conventional mining hammers generally adopt an integrated hammerhead and handle structure, which has significant limitations in actual use. When the hammerhead is damaged due to high-frequency impact or needs to be replaced with a specific specification hammerhead to adapt to different ore characteristics, the operator has to replace the entire hammerhead and handle assembly as a whole, or carry multiple mining hammers equipped with different hammerheads. This not only increases the operating cost and physical burden of carrying tools, but may also affect the surveying efficiency due to the inability to adapt to the optimal tool in time. Utility Model Content

[0004] In view of this, the present invention provides a mining hammer that is easy to use in mining exploration. It can be quickly disassembled and replaced through a quick-release mechanism, and the hammer head can be quickly replaced according to different materials of ore. At the same time, the replaced hammer head can be locked to prevent it from loosening during use, ensuring safety. There is no need to carry multiple mining hammers, which reduces operating costs and the physical burden of carrying tools.

[0005] To address the aforementioned technical problems, this utility model provides a mining hammer that is convenient for use in mining exploration. It includes a handle and a hammer head threadedly connected to its upper end. A quick-release mechanism is provided between the hammer head and the handle. The quick-release mechanism includes a dovetail groove located on the upper end of the outer arc surface of the handle. A limiting block is slidably connected within the dovetail groove. A limiting slot is provided at the lower end of the hammer head that movably engages with the limiting block. A spring is provided between the lower end of the limiting block and the bottom of the dovetail groove, enabling quick disassembly and replacement. This allows for rapid replacement of the hammer head according to different ore materials. Simultaneously, the replaced hammer head can be locked to prevent loosening during use, ensuring safety. The overall length of the mining hammer can be adjusted to enhance its striking power, reduce operator workload, and significantly lower the user's labor intensity.

[0006] It also includes an extension component, which includes an extension rod slidably connected to the lower end of the handle, thereby extending the length of the handle.

[0007] The extension assembly also includes several pressure plates disposed at the upper end of the extension rod. A threaded sleeve is threadedly connected to the upper end of the outer arc surface of the extension rod. The upper end of the inner cavity of the threaded sleeve is in active contact with the outside of the several pressure plates, thus achieving the purpose of initial locking.

[0008] The extension assembly also includes a locking head located on the upper inner side of each pressure plate. The outer arc surface of the handle is provided with several locking grooves. The locking head is movably inserted into the adjacent locking groove on the same side, which serves to further limit and lock the position.

[0009] The extension assembly also includes a rectangular rod located at the bottom of the inner cavity of the extension rod. The rectangular rod is slidably connected to a rectangular groove at the lower end of the handle, which serves as a guide and support for movement.

[0010] The lower end of the limiting block is equipped with a protective plate, which matches the opening end of the dovetail groove to prevent splashed ore fragments from entering the dovetail groove.

[0011] The outer surfaces of the pressure plates are all inclined inward from top to bottom to ensure stable pressure application.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] 1. When it is necessary to change to a different hammerhead, the operator first presses the limit block. The limit block overcomes the spring force and slides down along the dovetail groove. After the limit block separates from the limit slot on the hammerhead, the hammerhead is rotated counterclockwise to remove it from the handle. Then, the required hammerhead is replaced and threaded onto the handle. The limit block is then released, and it resets under the spring's return force, finally engaging with the limit slot on the new hammerhead. This allows for quick disassembly and replacement, enabling rapid hammerhead replacement according to different ore materials. It also locks the replaced hammerhead to prevent it from loosening during use, ensuring safety. It eliminates the need to carry multiple mining hammers, reducing operating costs and the physical burden of carrying tools.

[0014] 2. The extension rod is adjusted in length by slidingly connecting the rectangular rod to the rectangular groove of the handle. After the length is adjusted, tighten the threaded sleeve. When the threaded sleeve rotates, it will squeeze the outer inclined surface of the pressure plate, thereby deforming the pressure plate and causing the inner locking head to insert into the corresponding locking groove on the handle, thus fixing the extension rod. This can adjust the overall length of the mining hammer to enhance the striking strength of the mining hammer, reduce the labor of the operator, and significantly reduce the labor intensity of the user.

[0015] 3. Use a protective plate at the opening of the dovetail groove to prevent splashed ore debris from entering the dovetail groove. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0022] This embodiment provides a mining hammer that is easy to use in mining exploration, such as Figure 1-4 As shown: It includes a handle 100 and a hammer head 200 threaded to its upper end. A quick-release mechanism is provided between the hammer head 200 and the handle 100. The quick-release mechanism includes a dovetail groove 201 provided on the upper end of the outer arc surface of the handle 100. A limit block 202 is slidably connected in the dovetail groove 201. A limit slot is provided at the lower end of the hammer head 200, which is movably inserted into the limit block 202. A spring 203 is provided between the lower end of the limit block 202 and the bottom of the dovetail groove 201.

[0023] When it is necessary to replace the hammer head 200, the operator first presses the limit block 202. The limit block 202 overcomes the elastic force of the spring 203 and slides downward along the dovetail groove 201. After the limit block 202 separates from the limit slot on the hammer head 200, the hammer head 200 is rotated counterclockwise to remove it from the handle 100. Then, the hammer head 200 of the required specification is replaced and threaded into the handle 100. Then, the limit block 202 is released. At this time, the limit block 202 is reset under the action of the spring 203, and finally it is movably inserted into the limit slot on the new hammer head 200, realizing quick disassembly and replacement. The hammer head 200 can be quickly replaced according to different materials of ore. At the same time, the replaced hammer head 200 can be locked to prevent it from loosening during use and ensure safety.

[0024] like Figure 1-4As shown, it also includes an extension assembly, which includes an extension rod 300 slidably connected to the lower end of the handle 100. The extension assembly also includes several pressure plates 301 disposed on the upper end of the extension rod 300. A threaded sleeve 302 is threadedly connected to the upper end of the outer arc surface of the extension rod 300. The upper end of the inner cavity of the threaded sleeve 302 is in movable contact with the outside of the several pressure plates 301. The extension assembly also includes a locking head 303 disposed on the upper end of the inner side of each pressure plate 301. The outer arc surface of the handle 100 is provided with several locking grooves 304. The locking head 303 is movably inserted into the adjacent locking groove 304 on the same side. The extension assembly also includes a rectangular rod 305 disposed at the bottom of the inner cavity of the extension rod 300. The rectangular rod 305 is slidably connected to the rectangular groove disposed at the lower end of the handle 100. The outer surfaces of the pressure plates 301 are all inclined inward from top to bottom.

[0025] The extension rod 300 is slidably connected to the rectangular groove of the handle 100 via the rectangular rod 305 to adjust its length. After the length is adjusted, the threaded sleeve 302 is tightened. When the threaded sleeve 302 rotates and moves, it will squeeze the outer inclined surface of the pressure plate 301, thereby deforming the pressure plate 301 and causing the inner locking head 303 to insert into the corresponding locking groove 304 on the handle 100, thereby fixing the extension rod 300. This can adjust the overall length of the mining hammer to enhance the striking strength of the mining hammer, reduce the labor of the operator, and significantly reduce the labor intensity of the user.

[0026] like Figure 2-3 As shown, the lower end of the limiting block 202 is provided with a protective plate 400. The protective plate 400 cooperates with the opening end of the dovetail groove 201. The protective plate 400 can block the opening end of the dovetail groove to prevent splashed ore fragments from entering the dovetail groove.

[0027] The working principle of the mining hammer provided by this utility model, which is convenient for mining exploration, is as follows: When it is necessary to replace different hammerheads 200, the operator first presses the limiting block 202. The limiting block 202 overcomes the elastic force of the spring 203 and slides downward along the dovetail groove 201. After the limiting block 202 separates from the limiting slot on the hammerhead 200, the hammerhead 200 is rotated counterclockwise to remove it from the handle 100. Then, the required hammerhead 200 is replaced and threaded onto the handle 100. Then, the limiting block 202 is released. At this time, the limiting block 202 returns to its original position under the action of the spring 203, and finally, it is movably inserted into the limiting slot on the new hammerhead 200, realizing quick disassembly and replacement. It can quickly replace the hammerhead 200 according to different materials of ore. The extension rod 300 can lock the replaced hammer head 200 to prevent it from loosening during use and ensure safety. It works in conjunction with the protective plate 400 at the opening end of the dovetail groove to prevent splashed ore debris from entering the dovetail groove. At the same time, the extension rod 300 is slidably connected to the rectangular groove of the handle 100 through the rectangular rod 305 to adjust the length. After the length is adjusted, the threaded sleeve 302 is tightened. When the threaded sleeve 302 rotates and moves, it will squeeze the outer inclined surface of the pressure plate 301, thereby deforming the pressure plate 301 and causing the locking head 303 on the inner side to insert into the corresponding locking groove 304 on the handle 100, thereby fixing the extension rod 300. It can adjust the overall length of the mining hammer to enhance the striking strength of the mining hammer, reduce the labor of the operator, and significantly reduce the labor intensity of the user.

[0028] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
