Description

Technical Field

[0001] This utility model relates to the field of metal crusher technology, and in particular to a high-efficiency crushing tooth casting for a metal crusher. Background Technology

[0002] A metal shredder, also known as a metal crusher, is a machine used to crush scrap metal materials. Depending on the material it crushes, it may also be called a scrap iron shredder, aluminum can shredder, scrap steel shredder, paint bucket shredder, etc. These are all general terms for metal shredder equipment. A complete metal shredder production line is formed by configuring a metal shredder with a qualified production line. Metal shredders process various scrap metals (steel, alloys, non-ferrous metals, etc.) with extremely high hardness. During the repeated and violent impacts, shearing, and tearing process with these hard metals, the surface material of the shredding teeth is rapidly worn away and peeled off.

[0003] The existing technical solutions mentioned above have the following drawbacks: the crushing teeth of existing crushers are all integrated with the rotating roller shaft. Once a tooth is damaged, the entire machine needs to be replaced, which increases maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency crushing tooth casting for a metal crusher.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A high-efficiency crushing tooth casting for a metal crusher includes a rotating roller shaft. A connecting seat is engaged with the outer side of the rotating roller shaft. Crushing teeth and a fixing member are fixedly connected to the outer side of the connecting seat. A lifting ring threaded hole is opened inside the fixing member. A mounting plate is fixedly connected to the outer side of the connecting seat near the fixing member. A first positioning groove and a first through hole are opened inside the mounting plate. A positioning block is fixedly connected to the outer side of the mounting plate. A clamping plate is installed on the outer side of the mounting plate. A second through hole, a positioning hole, and a second positioning groove are opened inside the clamping plate. A locking bolt is inserted into the second through hole. A mounting threaded hole is opened inside the rotating roller shaft. A positioning rod is fixedly connected to the outer side of the rotating roller shaft.

[0006] By adopting the above technical solution, the crushing teeth are designed as a detachable structure, which can be assembled and spliced ​​by snap-fit ​​installation. This makes the crushing teeth no longer a fixed structure. When damaged, the damaged part can be directly disassembled and replaced without replacing the whole thing. This is convenient, quick, and reduces maintenance costs. After the connecting seat is engaged with the rotating roller shaft, the mounting plate is engaged with the connecting seat from the side to fix the connecting seat. Then, it is locked and fixed with locking bolts. This makes it convenient to first position and splice the parts, and then lock and fix them.

[0007] Furthermore, multiple of the connecting seat, crushing teeth, fixing parts, lifting ring connecting threaded holes, mounting plates, first positioning grooves, first through holes, and positioning blocks are provided. The first positioning groove and the positioning rod are engaged in engagement, and the positioning block and the second positioning groove are engaged in engagement.

[0008] By adopting the above technical solution and adding multiple sets of crushing teeth, the corresponding parts can be replaced in a timely manner after damage, which is convenient and quick.

[0009] Furthermore, multiple clamping plates, second through holes, positioning holes, second positioning grooves, mounting threaded holes, and positioning rods are provided respectively. The clamping plates and mounting plates are engaged and connected. The locking bolts pass through the first through holes and the second through holes and extend into the interior of the mounting threaded holes, and are threadedly connected to the mounting threaded holes. The positioning holes and positioning rods are engaged and connected.

[0010] By adopting the above technical solutions, the stability of the structure after installation is improved, and operation and use are facilitated.

[0011] In summary, the beneficial technical effects of this utility model are as follows: The system employs a connecting seat, mounting plate, crushing teeth, clamping plate, locking bolts, positioning block, and positioning rod. Multiple sets of connecting seats are engaged on the outside of the rotating roller shaft, and each connecting seat has crushing teeth on its outer side. The outer side of the connecting seat is also equipped with a clamping plate for installation, which, together with the locking bolts, secures the device. The installation section is further enhanced with positioning blocks and positioning rods, allowing for initial positioning and installation followed by locking, thus improving the accuracy and stability of the structural installation. In the future, only damaged parts of the crushing teeth need to be replaced, resulting in convenient installation and use. Attached Figure Description

[0014] The present invention will be further described in detail below with reference to the accompanying drawings.

[0015] Reference Figure 1-4 A high-efficiency crushing tooth casting for a metal crusher includes a rotating roller shaft 1. A connecting seat 2 is engaged with the outer side of the rotating roller shaft 1. Crushing teeth 3 and a fixing member 4 are fixedly connected to the outer side of the connecting seat 2. A lifting ring connecting threaded hole 5 is opened inside the fixing member 4. A mounting plate 6 is fixedly connected to the outer side of the connecting seat 2 near the fixing member 4. A first positioning groove 7 and a first through hole 8 are opened inside the mounting plate 6. A positioning block 9 is fixedly connected to the outer side of the mounting plate 6. A clamping plate 10 is installed on the outer side of the mounting plate 6. A second through hole 11, a positioning hole 12, and a second positioning groove 13 are opened inside the clamping plate 10. The internal part of the 11 is fitted with a locking bolt 14. The internal part of the rotating roller shaft 1 is provided with a mounting threaded hole 101. The outer side of the rotating roller shaft 1 is fixedly connected with a positioning rod 102. The crushing teeth 3 are designed as a detachable structure, which can be assembled and spliced ​​by snap-fit ​​installation. This makes the crushing teeth 3 no longer a fixed structure. If damaged, the damaged part can be directly disassembled and replaced without replacing the whole thing. This is convenient, quick and easy and reduces maintenance costs. After the connecting seat 2 is engaged with the rotating roller shaft 1, the mounting plate 6 is engaged with the connecting seat 2 from the side to fix the connecting seat 2. Finally, the locking bolt 14 is used to lock and fix it.
