The front end of the connecting handle is located inside the hammer block. The end of the hammer block away from the connecting handle is the working part, and the end connected to the connecting handle is the fixed part, extending the life of vulnerable parts. This utility model also provides a crusher hammer assembly. As described in the aforementioned patent, when using existing composite wear-resistant manganese steel hammer assembly structures for crushers, the device often cannot provide a certain degree of limiting treatment on the hammer handle end at the hammer mounting end as needed. This is not conducive to subsequent hammer handle installation and makes it difficult to provide buffering treatment for the hammer handle end. Consequently, during the subsequent material crushing process, the hammer assembly as a whole suffers a large impact, reducing the service life of the equipment. Utility Model Content

[0013] Beneficial effects

[0014] This utility model provides a composite wear-resistant manganese steel hammer assembly structure for crushers. Compared with the prior art, it has the following advantages:

[0015] 1. The composite wear-resistant manganese steel hammer assembly structure for the crusher, through the installation of mounting parts inside the device, allows the stop bar to fit against each other on adjacent positioning plates during the installation of the positioning plate, thus limiting the adjacent positioning plates. This facilitates the subsequent installation of the positioning plates on the drive column. During hammer installation, the stop bar and the limiting block limit the hammer. During the crushing process of the hammer, the limiting block and the spring assembly cooperate to buffer the hammer handle end, reducing the impact and damage to the hammer handle, shaft pin, positioning plate, and drive column, and extending the service life of the equipment.

[0016] 2. The composite wear-resistant manganese steel hammer assembly structure for the crusher, by setting sliders in the device, allows the sliders on both sides to slide along the receiving groove as the limiting block slides along the arc groove, thus protecting the spring assembly and preventing material debris from falling into the arc groove in the positioning plate during the crushing process. This avoids the impact of the buffer on the positioning block caused by the crushed material getting stuck in the spring of the spring assembly. Attached Figure Description

[0026] Several mounting parts 2 are respectively installed on the drive column 1 for the installation of the crushing component. The mounting part 2 includes a positioning disk 21 that is slidably connected to the drive column 1. The edge of the positioning disk 21 is provided with an array of through holes 22. Four sets of buffer parts 23 for providing buffer for the hammer handle end are respectively installed on the upper and lower edges of the positioning disk 21 near the two ends of the through holes 22. The buffer part 23 includes a limiting block 231 that is slidably connected to the positioning disk 21. The two sides of the limiting block 231 are respectively fixedly connected to the slider 232 that is slidably connected to the positioning disk 21. The lower side of the limiting block 231 near the slider 232 is a spring assembly 233 connected to the positioning disk 21. Several stop bars 24 for limiting the hammer handle are fixedly connected to the edge of the positioning disk 21 corresponding to the several through holes 22. The upper and lower sides of the middle part of the positioning disk 21 are respectively connected to a first bolt and nut assembly 25 for fixing the drive column 1.

[0027] Several hammerheads 3 are respectively installed on the edges of adjacent positioning discs 21 and are in contact with buffer components 23 and stop bars 24; anti-detachment components 4 are installed on several positioning discs 21 for anti-detachment treatment of hammerheads 3; drive column 1 is rotatably connected inside the crusher and connected to the drive end of the crusher; hammerheads 3 are made of composite wear-resistant manganese steel; the positioning disc 21 is provided with an arc-shaped groove that is slidably connected to the limit block 231; spring assembly 233 is located in the arc-shaped groove; the springs in the spring assembly 233 are fixedly connected to the limit block 231 and the positioning disc 21 respectively; the limit block 231 is in contact with the side of the hammer handle of hammerhead 3;

[0028] The first bolt in the first bolt and nut assembly 25 is slidably connected to the drive column 1 and the positioning plate 21 respectively. The first bolt in the first bolt and nut assembly 25 is threadedly connected to the first nut that fits against the positioning plate 21. The anti-detachment component 4 includes a shaft pin 41 that is slidably connected to several through holes in the positioning plate 21 and the hammer handle end of the hammer head 3. The bottom of the shaft pin 41 is connected to the second bolt and nut assembly 42 near the lower side of the positioning plate 21. The second bolt in the second bolt and nut assembly 42 is slidably connected to the shaft pin 41. The end of the second bolt in the second bolt and nut assembly 42 is threadedly connected to the second nut that is threadedly connected to the shaft pin 41. During the installation of the positioning plate 21, the stop bar 24 plays a limiting role for the adjacent positioning plate 21. During the installation of the hammer head 3, the stop bar 24 and the limiting block 231 play a limiting role for the hammer head 3. During the crushing of materials by the hammer head 3, the limiting block 231 and the spring assembly 233 cooperate with each other to buffer the hammer handle end of the hammer head 3.

[0029] The main difference between the second implementation method and the first implementation method is that:

[0030] The positioning plate 21 has a storage groove that is slidably connected to the slider 232. The hammer head 3 has a vertically penetrating docking hole that matches the through hole 22. A set of wear-resistant sleeves are installed in the through hole 22 and the docking hole respectively.

[0031] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0032] In use, the user slides the central groove of the positioning disc 21 to the drive column 1. After the positioning disc 21 is moved to a suitable position on the drive column 1, the user fixes the positioning disc 21 to a suitable position on the upper side of the drive column 1 using the first bolt and nut assembly 25. Repeat the above operation to fix several positioning discs 21 to the drive column 1. Several stop bars 24 between adjacent positioning discs 21 are in contact with each other. The hammer handle end of the hammer head 3 is inserted through two sets of limiting blocks 231 around the adjacent positioning disc 21. At this time, the four sets of limiting blocks 231 are respectively in contact with both sides of the hammer handle end of the hammer head 3. After the hammer handle end of the hammer head 3 contacts the stop bar 24, the insertion of the hammer head 3 is stopped. The above storage operation is repeated for several adjacent positioning discs 21 near the other positions of the hammer head 3. Then, the shaft pin 41 is inserted into several During this process, the position of the hammer head 3 is finely adjusted through the through hole 22 on the positioning plate 21 so that the shaft pin 41 is also slidably connected to the shaft pin 41 through several hammer head 3 mating holes. Then, it is connected to the shaft pin 41 through the second bolt and nut assembly 42 to achieve anti-detachment treatment between the shaft pin 41 and the positioning plate 21. The above operation is repeated to install the hammer head 3 on the remaining ends of the positioning plate 21. During the process of the external driving component driving the drive column 1 to rotate, several mounting parts 2 and anti-detachment parts 4 cooperate with each other to drive several hammer heads 3 to rotate. When the hammer head 3 comes into contact with the material to be crushed, the hammer head 3 crushes the material. At the same time, the four sets of limit blocks 231 and spring assembly 233 on both sides of the hammer head 3 handle provide buffering for the hammer head 3 handle and play a protective role.
