For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] See also Figure 1-3 The invention discloses a hammer head assembly for a coal mine hammer breaker which is easy to disassemble, comprising a hammer head body 1 and an adjusting component, wherein the adjusting component is arranged at the bottom of the hammer head body 1.

[0031] A hammer head 4 is arranged on the front of the hammer body 1, and a wear-resistant layer 14 is arranged on the front of the hammer head 4 for crushing coal and mineral materials. The wear-resistant layer 14 can improve its wear resistance. A hole leading to the bottom is opened on the top of the hammer body 1, and a fixing bolt 3 is fixedly installed through the hole. A support block 5 is fixedly installed on the back side of the hammer body 1 by screws, and a positioning bottom shaft 6 is fixedly installed at the bottom of the hammer body 1.

[0032] In this embodiment, hammer side plates 2 are provided on both sides of the hammer body 1 . The hammer side plates 2 are inclined, and a fixing column 13 connected to the positioning bottom shaft 6 is fixedly installed on the inner side of the fixing bolt 3 .

[0033] It should be noted that the fixed clamping column 13 ensures a firm connection between the hammer body 1 and the positioning bottom shaft 6. The existence of the fixed clamping column 13 not only increases the stability of the connection, but also helps prevent the hammer body from shaking or falling off during operation, thereby ensuring the safety and stability of the hammer assembly.

[0034] The adjusting component comprises a positioning machine plate 7, on which the bottom of the positioning bottom shaft 6 is movably mounted, and a positioning thread groove 9 connected to the hammer crusher body is formed at the bottom of the positioning machine plate 7.

[0035] In this embodiment, the bottom of the positioning bottom shaft 6 is rotatably connected to a rotating main shaft 16, and the bottom of the rotating main shaft 16 is fixedly connected to the positioning machine plate 7. The rotating main shaft 16 can drive the hammer head body 1 at the top to rotate. The four corners of the bottom of the positioning machine plate 7 are provided with positioning card grooves 8 surrounding the positioning thread groove 9, and the positioning thread groove 9 is fixedly connected to the coal mine hammer crusher body.

[0036] It should be noted that the positioning slot 8 and the positioning threaded slot 9 are not only used for positioning, but also can increase the connection strength between the hammer head assembly and the hammer breaker body, help reduce vibration and shaking during operation, and improve the stability and reliability of the hammer head assembly.

[0037] In this embodiment, reset positioning columns 18 are installed at the four corners of the top of the positioning machine plate 7, and the four reset positioning columns 18 are on the same vertical line with the corresponding positioning slots 8. Four reset receiving columns 10 are fixedly installed at the bottom of the hammer head body 1, and the four reset receiving columns 10 are on the same vertical line with the corresponding reset positioning columns 18.

[0038] It should be noted that since the reset positioning column 18 and the corresponding positioning slot 8 and the reset receiving column 10 are all on the same vertical line, this design can ensure that the hammer head body 1 can be accurately docked with the positioning machine plate 7 during installation, which not only improves the installation efficiency, but also avoids failures or damages caused by inaccurate installation position.

[0039] In this embodiment, a rotating main shaft 16 is fixedly installed on the top of the positioning machine plate 7, and the rotating main shaft 16 is rotatably connected to the bottom of the positioning bottom shaft 6. A plurality of engaging grooves 17 are opened on the outer side of the rotating main shaft 16. A transmission device 15 is fixedly installed on the bottom of the support block 5, and an engaging column 11 is fixedly installed on the front of the transmission device 15. A engaging telescopic shaft 12 is transmission-installed on the inner side of the engaging column 11, and the other side of the engaging telescopic shaft 12 is further transmission-connected with the engaging column 11. The end of the engaging column 11 away from the transmission device 15 can be engaged with the inner side of the engaging groove 17.

[0040] It should be noted that the rotational connection between the rotating main shaft 16 and the positioning bottom shaft 6 and the snap-fit ​​cooperation between the snap-fit ​​groove 17 and the snap-fit ​​column 11 jointly enhance the structural stability of the hammer head assembly. The extension and retraction of the snap-fit ​​telescopic shaft 12 is controlled by the transmission device 15, and then the snap-fit ​​column 11 is driven to engage in or disengage from the snap-fit ​​groove 17, thereby realizing rapid adjustment of the angle of the hammer head body 1.

[0041] The working principle of the above embodiment is:

[0042] When the hammer body 1 needs to be installed on the hammer crusher, first connect the positioning machine plate 7 to the hammer crusher body through the positioning thread groove 9, and then rotatably connect the bottom of the positioning bottom shaft 6 to the rotating main shaft 16. At this time, due to the corresponding relationship between the reset positioning column 18 and the reset receiving column 10, the hammer body 1 can be accurately aligned and installed on the positioning machine plate 7.

[0043] In addition, in order to achieve the angle adjustment of the hammer head body 1, a transmission device 15 is installed at the bottom of the support block 5, and a locking column 11 is fixedly installed on the front of the transmission device 15. The inner side of the locking column 11 is transmission-installed with a locking telescopic shaft 12. When the angle of the hammer head body 1 needs to be adjusted, the transmission device 15 is operated to make the locking telescopic shaft 12 extend and retract and be locked in the locking groove 17 on the outside of the rotating main shaft 16, thereby achieving the angle adjustment of the hammer head body 1.

[0044] The beneficial effects of the above embodiments are:

[0045] Through the cooperation of the transmission device 15 and the locking column 11, the locking telescopic shaft 12 can be extended and locked in the locking groove 17, so as to realize the angle adjustment of the hammer head body 1. It can be flexibly adjusted, which improves its adaptability and work efficiency. At the same time, with the help of the design of the reset positioning column 18 and the reset receiving column 10, the accurate docking between the hammer head body 1 and the positioning machine plate 7 is further guaranteed, which improves the convenience and stability of installation.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
