Description

Technical Field

[0001] This utility model relates to the field of alloy hammer technology, specifically to alloy hammers made of tungsten carbide stacks. Background Technology

[0002] In the material crushing process, tungsten carbide alloy hammers, as one of the core components of a pulverizer, directly determine the crushing effect and efficiency. In many traditional pulverizers, the hammers are usually long strips or rectangles. While this design can meet basic crushing requirements, in actual operation, due to the uniform mass distribution of the hammers, they cannot generate sufficient centrifugal force during rotation, resulting in a relatively weak impact effect. Furthermore, the contact between the impact surface of traditional hammers and the material is not always optimal, leading to insufficient material crushing upon collision with the hammers, thus affecting crushing efficiency. Utility Model Content

[0003] The purpose of this invention is to provide alloy hammer blades for tungsten carbide stacks. By designing the hammer blade body with a top-heavy structure, a stronger centrifugal force is generated when the hammer blade is swung up. This weight-increasing design improves the impact effect of the hammer blades, increases the crushing capacity of materials, and makes the working end face of the hammer blade body into a bevel, pushing the material to both sides when hammering it, reducing the material's movement speed with the rotating hammer blade, increasing the impact speed difference between the subsequent hammer blades and the material, greatly improving the crushing efficiency, and solving the problems in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an alloy hammer blade for a tungsten carbide stack, comprising a main shaft, wherein a plurality of equidistantly distributed connecting discs are provided on the outer wall of the main shaft, and a rotor is provided on the outside of the main shaft, wherein both ends of the rotor are fixed to nuts through the connecting discs, and a hammer blade assembly is fixedly provided on the rotor, wherein the hammer blade assembly is located between adjacent connecting discs, and the hammer blade assembly comprises two hammer blade bodies and a connecting block, wherein the two hammer blade bodies are respectively located in the limiting grooves opened in the connecting block.

[0005] Preferably, the hammer body includes a first wear-resistant body and a second wear-resistant body, which are integrally formed by laser welding.

[0006] Preferably, the first wear-resistant body has a pin hole inside, and a countersunk hole is formed on the side of the pin hole near the second wear-resistant body.

[0007] Preferably, the weight of the second wear-resistant body is greater than the weight of the first wear-resistant body, and both ends of the second wear-resistant body are machined into a beveled edge shape.

[0008] Preferably, the connecting block has an irregularly shaped hole inside, and an irregularly shaped shaft is provided inside the irregularly shaped hole. Both ends of the irregularly shaped shaft have screw holes.

[0009] Preferably, the hammer body is connected to the screw hole by bolts.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. The alloy hammer blades of this utility model for tungsten carbide stacks, by designing the hammer blade body with a top-heavy structure, generate stronger centrifugal force when the hammer blades are swung up. This weight-increasing design improves the impact effect of the hammer blades, increases the crushing capacity of materials, and makes the working end face of the front end of the hammer blade body into a bevel, pushing the material to both sides when hammering, reducing the movement speed of the material as it rotates with the hammer blades, increasing the impact speed difference between the subsequent hammer blades and the material, and greatly improving the crushing efficiency.

The alloy hammer of the tungsten carbide stack of this utility model has a countersunk hole on the side of the pin hole near the second wear-resistant body, and an irregular hole is opened inside the connecting block. An irregular shaft is inserted into the irregular hole, and threaded holes are opened at both ends of the irregular shaft. The hammer body is connected to the threaded hole by bolts. Through the cooperation of bolts and irregular shaft, the connection between the hammer body and the connecting block has higher stability and avoids the risk of loosening due to vibration or external force.

[0017] 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.

[0018] Please see Figure 1-3 This embodiment provides the following technical solution:

[0019] The alloy hammer blades of the tungsten carbide stack include a main shaft 1. Multiple equidistant connecting discs 2 are arranged on the outer wall of the main shaft 1. A rotor 3 is arranged outside the main shaft 1. Both ends of the rotor 3 pass through the connecting discs 2 and are fixed with nuts. A hammer blade assembly 4 is fixedly arranged on the rotor 3, and the hammer blade assembly 4 is located between adjacent connecting discs 2. The hammer blade assembly 4 includes two hammer blade bodies 401 and a connecting block 403. The two hammer blade bodies 401 are respectively located in the limiting grooves 404 opened in the connecting block 403.

[0020] In this embodiment, the hammer body 401 includes a first wear-resistant body 40101 and a second wear-resistant body 40102. The first wear-resistant body 40101 and the second wear-resistant body 40102 are integrally formed by laser welding. The weight of the second wear-resistant body 40102 is greater than that of the first wear-resistant body 40101. Both ends of the second wear-resistant body 40102 are processed into a beveled edge shape. The working surface of the hammer body 401 is a planar structure. When the material is struck at high speed, the material will be pushed directly forward. By making the working end face of the front end of the hammer body 401 beveled, the material is pushed to both sides when it is struck, which reduces the movement speed of the material following the rotation of the hammer and increases the hammering speed difference between the subsequent hammer and the material, thereby improving the crushing efficiency. The first wear-resistant body 40101 and the second wear-resistant body 40102 are integrally formed by laser welding. In this way, the second wear-resistant body 40102 part of the entire hammer body 401 is heavier to increase the striking force of the hammer body 401 when it rotates.

[0021] In this embodiment, the first wear-resistant body 40101 has a pin hole 40104 inside, and the pin hole 40104 has a countersunk hole 40105 on the side near the second wear-resistant body 40102. The connecting block 403 has a shaped hole 406 inside, and a shaped shaft 405 is provided inside the shaped hole 406. Both ends of the shaped shaft 405 have screw holes 407. The hammer body 401 is threadedly connected to the screw holes 407 by bolts 402. The cooperation between the bolts 402 and the shaped shaft 405 makes the connection between the hammer body 401 and the connecting block 403 more stable, avoiding the risk of loosening due to vibration or external force.

[0022] Working principle: In use, first connect the hammer body 401 to the connecting block 403, insert the irregular shaft 405 into the irregular hole 406, and then thread the bolt 402 through the countersunk hole 40105 and the screw hole 407. The cooperation between the bolt 402 and the irregular shaft 405 makes the connection between the hammer body 401 and the connecting block 403 more stable. The hammer assembly 4 is set on the rotor 3. The drive motor drives the main shaft 1 to rotate. The rotation of the main shaft 1 drives the connecting disc 2 and the rotor 3 to rotate together. The high-speed rotation of the main shaft 1 drives the hammer body 401 to rotate. 1. The material is impacted to crush it. When the material is struck at high speed, the working end face of the front end of the hammer body 401 is made into an inclined surface. When the material is struck, it is pushed to two sides, which reduces the movement speed of the material as it rotates with the hammer and increases the impact speed difference between the subsequent hammer and the material, thereby improving the crushing efficiency. The first wear-resistant body 40101 and the second wear-resistant body 40102 are laser-welded into one piece. In this way, the second wear-resistant body 40102 part of the entire hammer body 401 is biased to increase the impact force of the hammer body 401 when it rotates.
