DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Please refer to Figures 1-4. The utility model provides the following technical solutions: a wear-resistant tooth plate of a crusher that is easy to replace, including a base plate 1 and a tooth plate body 3. The top of the base plate 1 is fixedly connected with a plurality of clamping seats 2, and the top of the clamping seats 2 is plugged with the tooth plate body 3.

[0024] It should be noted that the tooth plate body 3 is a high manganese steel wear-resistant tooth plate. The tooth plate made of high manganese steel has excellent wear resistance and can be used for a long time.

[0025] Two plug-in rods 4 are plugged into the left and right sides of the back of the card seat 2, and the backs of the two left plug-in rods 4 and the right plug-in rod 4 are fixedly connected with a pull cover 5, and the front of the pull cover 5 is fixedly connected to a positioning rod 6 whose end passes through the card seat 2 and the tooth plate body 3 in sequence and extends to the outside of the front card seat 2.

[0026] In the above embodiment, a snap-fit ​​adapter groove is provided at the top of the snap-fit ​​seat 2, and a snap-fit ​​protrusion is protruded from the bottom of the tooth plate body 3, which is matched with the snap-fit ​​adapter groove. Therefore, after all limiting relationships are released, the tooth plate body 3 can be directly lifted up to disengage from the connection relationship with the snap-fit ​​adapter groove, thereby completing the replacement process.

[0027] In order to further achieve the purpose of facilitating replacement, a positioning and disassembly component is fixedly connected to the front side of the base plate 1 to stably position the tooth plate and flexibly disassemble it.

[0028] In addition, the positioning and disassembly assembly includes a mounting frame 7 and a magnetic frame 17. The mounting frame 7 is fixedly connected to the front of the base plate 1, and the magnetic frames 17 are fixedly connected to the left and right sides of the front of the base plate 1. The left and right sides of the top of the mounting frame 7 are bearing-connected to the rotating shaft 8, the top of the rotating shaft 8 is fixedly connected to the threaded rod 9, the outer side of the threaded rod 9 is threadedly connected to the threaded sleeve 10, and the north side of the threaded sleeve 10 is fixedly connected to the side frame 11, the bottom of the side frame 11 is fixedly connected to the telescopic rod 12, and the bottom of the telescopic rod 12 is fixedly connected to the mounting frame 7.

[0029] In addition, a threaded engagement groove is provided on the inner side wall of the threaded sleeve 10, and the threaded engagement groove is threadably matched with the threaded strip on the outer side of the threaded rod 9. A hand wheel is fixedly connected to the outer side of the rotating shaft 8. The telescopic rod 12 is a combined structure, which is composed of an outer rod and an inner rod. The inner movably connected part of the outer rod has one end that penetrates and extends to the outer side of the outer rod. By setting a matching relationship in which the threaded rod 9 and the threaded sleeve 10 are threadedly engaged, the threaded rod 9 can have the function of up and down displacement, and then the subsequent disassembly and adjustment process can be implemented. In this embodiment, the telescopic rod 12 can limit the displacement of the threaded sleeve 10 to avoid the phenomenon of the threaded sleeve 10 rotating in place. Finally, by setting a hand wheel, the worker can operate more conveniently and labor-saving.

[0030] Among them, the positioning and disassembly assembly also includes two fixing frames 13, the backs of the two fixing frames 13 are fixedly connected to the threaded sleeves 10 on the left and right sides respectively, the top of the fixing frame 13 is fixedly connected with a connecting piece 14, the top of the connecting piece 14 is fixedly connected with a top plate 15, the bottom of the top plate 15 is fixedly connected with a plurality of iron limiting rods 16 that penetrate to the bottom of the positioning rod 6, and the bottom of the iron limiting rod 16 is magnetically connected to the magnetic suction frame 17.

[0031] It can be understood that in the above embodiment, the iron limit rod 16 maintains a magnetic connection with the magnetic bracket 17 after positioning, further enhancing the connection stability. The working principle of this embodiment is as follows:

[0032] When the tooth plate body 3 needs to be replaced after long-term use, the threaded rod 9 is driven to rotate by rotating the rotating shaft 8. At this time, the threaded strip on the outer side of the threaded rod 9 is in threaded contact with the threaded groove provided on the inner wall of the threaded sleeve 10. The position of the threaded sleeve 10 is limited by setting the telescopic rod 12, thereby driving the threaded sleeve 10 to move up and down. During the upward movement of the threaded sleeve 10, the fixing frame 13 and the connecting piece 14 will also be driven to move upward, thereby driving the top plate 15 and the iron limiting rod 16 to move upward. During the upward movement of the iron limiting rod 1, it will be separated from the magnetic connection relationship with the magnetic suction frame 17 and finally separated from the interior of the positioning rod 6. At this time, the positioning rod 6 is released from the limit. Finally, the positioning rod 6 is pulled backward to make the plug-in rod 4 separate from the plug-in relationship with the clamping seat 2 and be pulled out of the clamping seat 2 and the interior of the tooth plate body 3. Finally, the tooth plate body 3 can be pulled upward to take out the tooth plate body 3 for replacement.
