Description

Technical Field

[0001] This utility model relates to the field of jaw crusher technology, and in particular to a novel crusher tooth plate. Background Technology

[0002] Jaw crushers are widely used in the smelting, road, water conservancy, mining and chemical industries for crushing various ores and large materials. In the vanadium product and ferrovanadium finished product process, the fixed tooth plates of the 1-2# heavy crusher have serious defects such as short service life, wear, and cracks, and poor left and right movement and positioning.

[0003] The packaging of finished ferrovanadium products has relatively small requirements for particle size. Therefore, the maximum compressive strength of crushed ferrovanadium is less than 120 MPa. The design compressive strength of the toothed plate is 180 MPa. The damage to the toothed plate itself is relatively low. The main cause of failure is the defect in its fixing method, which leads to left and right misalignment, toothed plate wear, and cracks. At the same time, the toothed plate slot gap is fixed, and fine powder often enters during operation, making disassembly difficult. The maintenance and repair process requires a lot of manpower, material resources, and time to achieve disassembly.

[0004] Therefore, how to improve maintenance efficiency and reduce the input of manpower, material resources, and time is a major problem that urgently needs to be solved under the increasingly rapid pace of production. Utility Model Content

[0005] This utility model improves the fixing method of jaw crusher tooth plates, aiming to solve the difficulties of investing a lot of manpower, material resources and time in the disassembly and replacement process and reduce maintenance and production costs. This utility model is urgently needed under the current production pace of increasing speed.

[0006] This utility model provides a novel crusher tooth plate, including a positioning block, a positioning hole, and a positioning bolt. The positioning block is installed in the positioning hole and fixed by the positioning bolt.

[0007] Preferably, the positioning block is provided with uniformly arranged wedge-shaped teeth.

[0008] Preferably, the length of the positioning block is 250mm-350mm.

[0009] Preferably, the tip length of the wedge-shaped tooth is 30mm-50mm.

[0010] Preferably, the thickness of the wedge-shaped tooth plate is 20mm-30mm.

[0011] Preferably, the tooth plate of the wedge-shaped tooth is made of Q235 carbon steel.

[0012] Preferably, the positioning bolt is a high-strength bolt with a compressive strength of 4.6.

[0013] Preferably, the diameter of the bolt hole is 17mm-18.5mm, and the bolt hole is located on the slot base at the corresponding position of the positioning block.

[0014] Preferably, the positioning bolt is M16*70mm.

[0015] Preferably, four positioning holes are symmetrically arranged.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] By widening the gap of the original tooth plate cavity and fixing it with positioning blocks, while using wedge-shaped teeth to ensure the fine adjustment of the opening degree of the crushing tooth plate during wear, the rigid connection between the positioning blocks and the crushing tooth plate is reduced, thereby achieving the purpose of protecting the crushing and fixing tooth plate.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] The vanadium ferrovanadium finishing process of the 1-2# heavy-duty crusher suffers from severe defects such as short service life, wear, and cracks in the fixed tooth plate, as well as poor lateral movement and positioning. Differences were identified by comparing the on-site operating environment with that of similar jaw crushers in the domestic industry. The packaging of vanadium ferrovanadium products has relatively small particle size requirements. The original design directly inserted the fixed tooth plate into the slot, relying solely on the slot gap for fixation, resulting in a short service life and poor positioning.

[0026] like Figure 1 As shown, this utility model provides a novel crusher tooth plate, including a positioning block 2, positioning holes, and positioning bolts. The positioning block 2 is installed in the positioning holes and fixed by the positioning bolts. The positioning holes are located at 30mm*20mm on both ends of the crusher tooth plate and are symmetrically arranged in four places.

[0027] The positioning block 2 is provided with uniformly arranged wedge-shaped teeth. The length of the positioning block 2 is 250mm-350mm, the length of the tooth tip 3 of the wedge-shaped teeth is 30mm-50mm, and the thickness 1 of the tooth plate of the wedge-shaped teeth is 20mm-30mm. The tooth plate of the wedge-shaped teeth is made of Q235 carbon steel.

[0028] The positioning bolts are high-strength bolts with a compressive strength of 4.6. The diameter of the bolt holes is 17mm-18.5mm, and the bolt holes are located on the slot base at the corresponding positions of the positioning block 2. The positioning bolts are M16*70mm in size.

[0029] This utility model cleverly utilizes the gap space in the crushing chamber's slots to create a dedicated positioning block 2. Wedge-shaped teeth ensure the crushing jaw plate's opening degree is finely adjusted to prevent wear, while simultaneously reducing the rigid connection between the positioning block 2 and the crushing jaw plate, thus protecting the fixed crushing jaw plate. The long-standing technical problems of traditional crusher jaw plates being directly inserted into the slots with a gap fit, leading to difficulties in replacement and disassembly when fine powder materials enter, and easily damaged parts, are solved by adding the wedge-shaped tooth positioning block. This innovative positioning block has a simple structure, is easy to manufacture, and brings significant convenience to actual operation and maintenance. More importantly, this positioning block 2 not only maintains the original crushing mechanical performance but also plays a role in fine-tuning the crushing opening degree. Its advanced design concept and excellent performance make it crucial in the online control of process particle size in jaw crushers. It not only effectively improves the efficiency of equipment replacement and disassembly, shortens the maintenance cycle, but also significantly reduces maintenance and production costs, while also providing a reference for equipment maintenance and improvement in related fields.

[0030] This invention addresses the problem of short service life caused by the left-right misalignment of the fixed tooth plate in a jaw crusher. By adding a positioning tooth plate, the contact area between the fixed tooth plate and the crushing chamber seat is increased, enhancing stability and ensuring smooth operation of the equipment while reducing the failure rate of similar products.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
