The sliding block is located between the two connecting rods and abuts against the two connecting rods at the same time.
[0021] By adopting the above technical solution, when the comb teeth are squeezed by steel slag, the comb teeth drive the sliding block to move, and at the same time the sliding block squeezes the connecting rod to one side, and the two connecting rods rotate relative to each other. One end of the connecting rod squeezes a buffer column, and the other end pulls a buffer column, thereby alleviating the impact of steel slag on the comb teeth, and also reducing the possibility of the comb teeth being deformed and damaged due to squeezing.

[0030] The present application is further described in detail below with reference to the accompanying drawings.
[0031] The embodiment of the present application discloses a slag crusher. Example
[0032] Reference Figure 1 and Figure 2 A slag crusher includes a casing 1, two parallel crushing rollers are provided inside the casing 1, the crushing rollers are rotatably connected to the casing 1, a coupling 6 is provided at one end of the crushing rollers, the crushing rollers are connected to a reducer 7 through the coupling 6, the reducer 7 is connected to a coupler 8 at one end away from the coupling 6, and the reducer 7 is connected to a drive motor 9 through the coupler 8, and the reducer 7 and the drive motor 9 are both installed on the casing 1.
[0033] The crushing shaft 5 is equipped with multiple evenly spaced tooth rings 4, coaxially arranged with the crushing shaft 5 and evenly distributed along its axis. The tooth rings 4 on two crushing shafts 5 are arranged in a staggered pattern, meaning that a tooth ring 4 from another crushing shaft 5 is positioned between adjacent tooth rings 4 on the same crushing shaft 5. The crushing teeth are evenly distributed along the circumference of the tooth rings 4. The crushing teeth on both crushing shafts 5 are arranged in a spiral direction, with opposite rotations, and are tapered.
[0034] Each drive motor 9 transmits torque to the crushing shaft 5 via a coupler 8, a speed reducer 7, and a coupling 6. As the two crushing shafts 5 rotate, their crushing teeth crush the slag. The crusher's spirally structured crushing teeth and staggered tooth ring 4 create a sieve-like structure, shearing, squeezing, and stretching the material, thereby controlling the discharge particle size. The conical crushing teeth facilitate crushing the slag, and the crushing teeth with opposite spiral directions compress and crush the slag, improving its crushing efficiency and overall crushing efficiency.
[0035] To protect the casing 1, a removable connecting plate 2 is installed inside the casing 1. The connecting plate 2 is threaded with fixing bolts that pass through the connecting plate 2 and are threadedly connected to the casing 1. A comb plate 3 is provided on the side of the connecting plate 2 near the crushing shaft 5. The comb plate 3 includes a tooth plate arranged parallel to the connecting plate 2. Fastening bolts are provided between the tooth plate and the comb plate 3 to connect the two. The tooth plate near the crushing shaft 5 is provided with multiple comb teeth, each of which is located between two adjacent tooth rings 4.
[0036] As the crushing shaft 5 rotates, the comb plate 3 combs away any slag stuck between adjacent crushing teeth, reducing the possibility of slag squeezing the casing 1. The connecting plate 2 inside the casing 1 also protects the casing 1, preventing slag from directly squeezing the casing 1. This further reduces the possibility of damage or deformation to the casing 1 and extends the life of the crusher. The connecting plate 2 and comb plate 3 can be installed and removed using bolts, allowing them to be replaced and adjusted, thereby adjusting the gap between the comb teeth and the gear ring 4.
[0037] The implementation principle of Example 1 is as follows: the driving motor 9 drives the crushing shaft 5 to rotate through the coupler 8, the reducer 7 and the coupling 6. The crushing teeth on the crushing shaft 5 crush the steel slag. At the same time, the comb plate 3 inside the casing 1 combs the steel slag stuck between the crushing teeth, reducing the possibility of the steel slag squeezing the casing 1 and causing deformation and damage to the casing 1. Example
[0038] Reference Figure 3The difference between this embodiment and embodiment 1 is that a buffer assembly 10 is provided between the comb teeth and the tooth plate, a buffer groove 31 corresponding to the comb teeth is opened on the tooth plate, and a sliding block 101 is fixed on the comb teeth and slidably connected to the buffer groove 31. The buffer assembly 10 includes a pair of cross-arranged connecting rods 102, and the intersection of the two connecting rods 102 is in a rotational connection with the tooth plate. A buffer column 103 is passed through the end of the connecting rod 102, and the buffer column 103 is installed at the corner of the buffer groove 31. The sliding block 101 is located between the two connecting rods 102 and abuts against the two connecting rods 102 at the same time.
[0039] When the comb teeth are squeezed by steel slag, the comb teeth drive the sliding block 101 to move, and at the same time the sliding block 101 squeezes the connecting rod 102 to one side, and the two connecting rods 102 rotate relative to each other. One end of the connecting rod 102 squeezes a buffer column 103, and the other end pulls a buffer column 103, thereby alleviating the impact of the steel slag on the comb teeth, and also reducing the possibility of the comb teeth being deformed and damaged due to squeezing.
[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
