Description

Technical Field

[0001] This utility model relates to the field of crusher blade technology, specifically a cemented carbide blade for crushers with anti-loosening features. Background Technology

[0002] A crusher is a machine that crushes large solid raw materials to the required size. It consists of coarse crushing, fine crushing, and pneumatic conveying devices. It achieves the purpose of crushing through high-speed impact and uses wind power to grind the raw materials into powder in one step, eliminating the traditional screening process. It is mainly used in mining, building materials and other industries.

[0003] For example, patent document CN 220803574 U discloses a blade for a pulverizer, including a main body and a pulverizing ring. The main body has an assembly hole and is annular in shape. The pulverizing ring has a connecting hole in the middle and three helical surfaces on its side. The intersection of adjacent helical surfaces forms the pulverizing section. The pulverizing ring includes a ring body and the pulverizing section, which are fixedly connected. The helix angle of the helical surfaces is 20 to 40 degrees. The pulverizing ring is fitted onto the main body through the connecting hole. The pulverizing section is made of cemented carbide. The pulverizing section of the blade is made of tungsten carbide cemented carbide, which improves the wear resistance of the blade compared to traditional alloy tool steel, thereby increasing the blade's service life. Furthermore, because tungsten carbide cemented carbide has higher hardness and better performance, it greatly increases the pulverizing range of the blade and improves its versatility.

[0004] However, when installing and using carbide blades for crushers, the device is limited by its own structure and cannot provide a more secure locking and clamping operation between the two sets of blades. This can easily lead to loosening and falling off. At the same time, the device cannot tighten the installation positions at both ends of all blades, which cannot meet the needs of daily use. Therefore, it is urgent to design a carbide blade for crushers with anti-loosening features to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a carbide blade for a crusher with anti-loosening features, in order to solve the problem mentioned in the background art that the existing mechanism for installing and using carbide blades for crushers is limited by its own structure and cannot provide a more secure limiting and locking installation operation between two sets of blades, which easily leads to loosening and falling off. At the same time, the equipment cannot tighten the installation positions at both ends of all blades, which cannot meet the needs of daily use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cemented carbide blade for a crusher with anti-loosening features, comprising a blade body, blade bodies evenly arranged on the side of the blade body, a connecting component arranged inside the blade body, and mounting components arranged at both ends of the blade body;

[0007] The connecting assembly includes a connector, one half of the inner wall of the tool body is fixedly connected to the connector, the other end of the connector is located outside one end of the tool body, and the connector is provided inside the connector.

[0008] The mounting assembly includes a first mounting base and a second mounting base. The first mounting base and the second mounting base are respectively provided at both ends of the tool body. One end of the second mounting base is provided with a mounting groove, which has the same internal structure as the tool body.

[0009] Preferably, a first ring seat is provided at one end edge of both the first mounting base and the second mounting base, a shrink sleeve is fixedly connected to one end of the first ring seat, and a second ring seat is provided at one end of the shrink sleeve.

[0010] Preferably, the inner wall of the connector is fixedly connected to a positioning inner ring, and the top end of the positioning inner ring is provided with a positioning groove.

[0011] Preferably, one end of the plug-in socket is provided with a third mounting base, and the top of the third mounting base is provided with a limiting plate, which is adapted to the positioning groove.

[0012] Preferably, the other end of the inner wall of the tool body is provided with an insertion groove, and the four sides of the inner wall of the insertion groove are provided with limit strips.

[0013] Preferably, the four sides of the plug-in socket are provided with limiting grooves.

[0014] Preferably, the tool bodies are interlocked and adapted to each other.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This anti-loosening carbide blade for crushers, through its blade body, insert socket, insert connector, first mounting base, positioning inner ring, positioning groove, limiting plate, insert groove, limiting strip, and limiting groove, allows for the anti-loosening insertion and installation of two sets of carbide blades for crushers. In actual use, the operator first inserts multiple sets of blade bodies one by one to align the blade bodies on the sides of the blade bodies. At this time, the blade bodies can be quickly inserted through the insert socket and the insert groove. The limiting strips on the four sides of the insert groove align with the limiting grooves on the four sides of the insert socket. At the same time, the limiting plate is inserted into the insert connector, and a firm limiting and locking operation is achieved through the positioning inner ring and positioning groove. This greatly improves the overall anti-loosening limiting connection effect of the carbide blades for crushers, demonstrating the practicality of the equipment design.

[0017] This anti-loosening carbide blade for a crusher, through its design including a blade body, a first mounting base, a second mounting base, a mounting groove, a first ring seat, a shrink sleeve, and a second ring seat, further improves the overall performance of the equipment. During daily use, operators can install the first and second mounting bases at both ends of the blade body. One end of the first mounting base is inserted into the internal groove of the blade body via a connector. The second mounting base, with the same structure as the connector groove, allows for insertion into the connector of the blade body. Simultaneously, the first and second mounting bases are securely fitted at both ends through the shrink sleeve between the first and second ring seats, providing end protection and demonstrating the comprehensiveness of the equipment design.
