Description

Technical Field

[0001] This utility model relates to the field of crusher auxiliary equipment technology, specifically a crusher rotor disc protector. Background Technology

[0002] A crusher, also known as a stone crusher, is a pulverizing machine used in the processing of metal and non-metal minerals to crush mined raw ore into small particles through compression and bending. A crusher is defined as a machine whose discharge contains more than 50% particles larger than three millimeters. Crushing operations are often classified into coarse crushing, medium crushing, and fine crushing according to the size of the feed and discharge particles. Commonly used crushing machines include jaw crushers, gyratory crushers, cone crushers, roller crushers, hammer crushers, and impact crushers. The vulnerable parts of a crusher generally include hammers and liners. The rotor disc is used to fix the hammers. During operation, the rotor disc of the crusher inevitably wears down after being impacted by the material, thus affecting its service life.

[0003] Patent CN211660232U discloses a protection device for a crusher rotor disc. Specifically, the patent discloses a technical solution that includes "a fixing plate, a protective plate at the top of the fixing plate, the protective plate and the fixing plate being an integral structure, and a pin fixing hole on the fixing plate". This solution achieves the technical effect of "avoiding frequent replacement and maintenance of the rotor disc, extending the service life of the rotor disc, and reducing the operating cost of the rotor disc".

[0004] However, the above-mentioned patents still have certain shortcomings in use. When protecting the rotor disc, they only rely on simple fixing plates and protective plates for external protection, which has poor protection effect and is not convenient for effective protection of the rotor disc. Therefore, we provide a crusher rotor disc protector to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a crusher rotor disc protector to solve the problems mentioned in the background art and overcome its technical defects.

[0009] As a further improvement of this utility model, a set of reinforcing ribs are connected to the back of the protective liner, and the reinforcing ribs are made of steel.

[0010] As a further improvement of this utility model: the protective liner is made of a high-hardness wear-resistant material, such as high-chromium cast iron or ceramic composite material, and the protective shell is made of high-strength alloy steel.

[0011] As a further improvement of this utility model: each protective shell has a gripping groove on its outer surface, and the gripping groove is located in the middle of the protective shell.

[0012] As a further improvement of this utility model: a keyway is provided on the inner wall of the mounting hole, and the keyway is located above the mounting hole.

[0013] As a further improvement of this utility model: a first model mark is provided on the front of the rotor disk body, and a second model mark is provided on the front of each protective shell.

[0014] Compared with the prior art, the beneficial effects of this utility model include: the protective shell made of high-strength alloy steel can wrap the rotor disk body, giving it good wear resistance and impact resistance, facilitating physical protection of the rotor disk body; and the protective liner made of high-hardness wear-resistant material and the buffer pad made of rubber material can effectively protect the rotor disk body externally, avoid contact with materials, and absorb and disperse impact force, reducing direct impact on the rotor disk body, thus achieving effective protection of the rotor disk body, increasing the protective effect of the rotor disk body, and facilitating the safe and durable use of the rotor disk body.

Detailed Implementation

[0021] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0022] According to one embodiment of the present invention, in conjunction with the appended drawings Figures 1-4 As shown.

[0023] A rotor disc protector for a crusher includes a rotor disc body 1. The front of the rotor disc body 1 has mounting holes 2 and a set of V-shaped holes 3. The back of the rotor disc body 1 has two sets of annularly arranged mounting screw holes 16. Two sets of protective shells 6 are fitted onto the outer surface of the rotor disc body 1. Each protective shell 6 has three fixing holes 15 on its back. Each fixing hole 15 has a fastening bolt 9 fitted onto its inner wall. The front end of each fastening bolt 9 is threaded into the inner wall of the mounting screw hole 16. A protective liner 10 is fitted onto the inner walls of both sets of protective shells 6. A circular cavity 13 is formed inside the protective liner 10, and a buffer pad 14 is fixedly connected to the inner wall of the circular cavity 13.

[0024] In this embodiment, the buffer pad 14 can be made of elastic materials such as rubber or polyurethane. When the material impacts the protector, the buffer pad 14 can absorb and disperse the impact force, reducing the direct impact on the rotor disc body 1. The protective liner 10 is connected to the protective shell 6 by two sets of fixing screws 12, which facilitates the replacement of the protective liner 10. A set of reinforcing ribs 11 is connected to the back of the protective liner 10. The reinforcing ribs 11 are made of steel, which can enhance the structural strength of the protective liner 10 and enable it to withstand greater impact forces.

[0025] In this embodiment, the protective liner 10 is made of a high-hardness wear-resistant material, such as high-chromium cast iron or ceramic composite material. The protective shell 6 is made of high-strength alloy steel, which can increase the overall strength of the protector and facilitate effective protection of the rotor disc body 1. Each protective shell 6 has a gripping groove 7 on its outer surface, which is located in the middle of the protective shell 6, making it easy to hold the protective shell 6 and facilitate its installation. The inner wall of the mounting hole 2 has a keyway 4, which is located above the mounting hole 2, and can limit the rotor disc body 1 during installation and use, facilitating the stable use of the rotor disc body 1. The front of the rotor disc body 1 has a first model number 5, and the front of each protective shell 6 has a second model number 8, which can describe the model of the protector and facilitate understanding and use of the protector.

[0026] Working principle: In use, the rotor disc body 1 is first installed through the mounting hole 2 and keyway 4. Then, the protective shell 6 is fitted onto the outside of the rotor disc body 1, and the fastening bolt 9 is threaded into the mounting screw hole 16 inside the fixing hole 15 to complete the installation of the protective shell 6, thereby achieving external protection for the rotor disc body 1 and increasing its wear resistance and impact resistance. Then, the protective liner 10 is fitted into the inside of the protective shell 6 and fixed with the fixing screw 12. The protective liner 10 prevents the rotor disc body 1 from directly contacting the material, increasing its wear resistance. The buffer pad 14 absorbs and disperses the impact force of the material, reducing the direct impact force on the rotor disc body 1, thus achieving effective protection for the rotor disc body 1 and ensuring its durable and safe use.

[0027] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
