[0016] This utility model proposes a hammer crusher hammer wear alarm device. By setting up a connecting assembly, during installation, the limiting blocks on both sides of the alarm device body engage with the first limiting groove inside the fixed frame. A pull rod in the sliding groove drives the insert rod to move via a spring, causing the pull rod to engage with the insert rod in the second limiting groove, thus installing the alarm device body. During disassembly and maintenance, pulling the pull rod in the second limiting groove back into the sliding groove, and the spring's rebound energy causes the insert rod to disengage from the second locking groove and retract to the inner surface of the frame, enabling rapid disassembly of the alarm device body. This allows operators to complete the installation and replacement of the wear alarm device in a short time, reducing equipment downtime and improving production efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 6 This utility model provides a technical solution: a hammer wear alarm device for a hammer crusher;

[0026] Example 1:

[0027] To facilitate rapid installation of the alarm device, a protective box 2 is fixedly installed on the upper surface of the mounting bracket 1. A connecting assembly is fixedly installed on the outer side of the protective box 2. The connecting assembly includes: a fixed frame 8, with two first limiting grooves 12 on the inner side of the fixed frame 8, an inner cavity 13 on the inner surface of the fixed frame 8, an alarm device body 14 on the inner surface of the inner cavity 13, two limiting blocks 15 fixedly installed on both sides of the alarm device body 14, and second slots 16 on the sidewalls of the limiting blocks 15. A frame 18 is fixedly installed on the outer side of the fixed frame 8, and a sliding groove 1 is provided on the upper surface of the frame 18. 9. A second limiting groove 23 is provided on the inner side of the slide groove 19. A spring 20 is fixedly connected to the inner side of the fixed frame 8. A plug rod 21 is fixedly connected to one end of the spring 20. A pull rod 22 is fixedly installed on the upper surface of the plug rod 21. By engaging the limiting blocks 15 on both sides of the alarm device body 14 with the first limiting groove 12 on the inner side of the fixed frame 8, the pull rod 22 in the slide groove 19 is slid to drive the plug rod 21 to move through the spring 20, so that the pull rod 22 drives the plug rod 21 to engage in the second limiting groove 23, thereby realizing the insertion of the plug rod 21 into the second slot 16, and thus installing the alarm device body 14.

[0028] Example 2:

[0029] Based on Embodiment 1, in order to achieve rapid disassembly of the alarm device, a first slot 11 is provided on the inner side of the first limiting groove 12. The insertion rod 21 is inserted and connected to the first slot 11 and the second slot 16. The alarm device body 14 is slidably installed in the inner cavity 13 through the limiting block 15, the first limiting groove 12, and the insertion rod 21 slides on the inner surface of the fixed frame 8 through the pull rod 22 and the sliding groove 19. The second limiting groove 23 is engaged with the pull rod 22. By pulling the pull rod 22 in the second limiting groove 23 back to the sliding groove 19, the elastic energy of the spring 20 drives the insertion rod 21 to disengage from the second slot 16 and retract to the inner surface of the frame 18, thereby achieving rapid disassembly of the alarm device body 14. This allows operators to complete the installation and replacement of the worn alarm device in a short time, reducing equipment downtime and improving production efficiency.

[0030] Working principle: To achieve rapid disassembly and assembly of the alarm device body 14, the limiting blocks 15 on both sides of the alarm device body 14 are engaged with the first limiting groove 12 inside the fixed frame 8. The pull rod 22 in the sliding groove 19 drives the insertion rod 21 to move via the spring 20, causing the pull rod 22 to engage the insertion rod 21 in the second limiting groove 23, thus connecting the insertion rod 21 to the second slot 16 and installing the alarm device body 14. Pulling the pull rod 22 in the second limiting groove 23 back into the sliding groove 19, and using the restoring energy of the spring 20, the insertion rod 21 disengages from the second slot 16 and retracts to the inner surface of the frame 18, thereby achieving rapid disassembly of the alarm device body 14. This allows operators to complete the installation and replacement of worn alarm devices in a short time, reducing equipment downtime and improving production efficiency.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
