Description

Technical Field

[0001] This utility model relates to the field of grinding mill blade technology, and in particular to a grinding mill blade that is easy to disassemble and assemble. Background Technology

[0002] A grinding mill is a device used to grind grains, materials, etc., into powder or fine particles. It is widely used in various industries such as food, chemical, and pharmaceutical. Its main purpose is to process lumpy, granular, or flaky raw materials into the desired powder or microparticle products through mechanical force. The grinding mill blades are a crucial component of the mill, and their quality and performance directly affect the mill's performance and lifespan.

[0003] Grinding mill blades are typically installed inside the grinding chamber of the grinding mill and are usually fixed to the mill using fasteners such as screws and nuts. This method of installing blades is rather cumbersome, increases the time and cost of replacing blades, and is inconvenient for users. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-7A grinding mill blade that is easy to assemble and disassemble includes a grinding chamber 1. A rotating main shaft 11 is rotatably mounted inside the grinding chamber 1. A mounting column 12 is fixedly and vertically mounted on the top of the rotating main shaft 11, and a detachable blade assembly 2 and a top cover 3 are sequentially mounted on the mounting column 12. A locking post 31 is fixedly and vertically mounted on both sides of the bottom of the top cover 3. A locking cavity 13 is adapted to fit the locking post 31 on the rotating main shaft 11, and a limiting plate 4 for locking the locking post 31 is movably mounted inside the rotating main shaft 11.

[0023] The blade assembly 2 has a mounting cavity 22 adapted to the mounting post 12, and the bottom of the top cover 3 has a top cavity 32 adapted to the mounting post 12. Since the mounting post 12 is polygonal, assembling the blade assembly 2 and the top cover 3 onto the mounting post 12 can drive the blade assembly 2 and the top cover 3 to rotate synchronously with the mounting post 12 and the rotating spindle 11.

[0024] In this design, each of the corresponding retaining posts 31 on the blade assembly 2 is provided with a through hole 21, and each retaining post 31 is provided with a limiting cavity 311. The through holes 21 allow the retaining posts 31 to pass through the blade assembly 2.

[0025] The rotating spindle 11 has inwardly extending movable cavities 14 on both sides, each containing a limiting plate 4, and both cavities 14 are adapted to and connected to the locking cavity 13. By locking the limiting plate 4 into the limiting cavity 311, the locking post 31 can be fixed, thereby fixing the top cover 3 and the blade assembly 2.

[0026] Each movable cavity 14 is equipped with multiple springs 5, the other end of which is connected to the limiting plate 4. The limiting plate 4 has a side cavity 41 corresponding to the locking post 31. By using the springs 5, the limiting plate 4 can be pushed outward, so that the limiting plate 4 can be stably locked in the limiting cavity 311.

[0027] Guide members 141 are fixedly installed on the inner wall of the movable cavity 14, and guide grooves 42 are opened on both sides of the limiting plate 4 to adapt to the guide members 141. Through the adaptation and locking between the guide members 141 and the guide grooves 42, not only can the limiting plate 4 be guided, but also the limiting plate 4 can be prevented from falling out of the movable cavity 14.

[0028] In this embodiment, the rotation of the main shaft 11 drives the mounting column 12, the blade assembly 2, and the top cover 3 to rotate synchronously, thereby achieving the grinding of materials in the crushing chamber 1 through the rotation of the blade assembly 2. It is worth noting that the specific structure of the main shaft 11 and the blade assembly 2, as well as their grinding methods, are existing technologies and will not be described in detail here.

[0029] Furthermore, when the user needs to install the blade assembly 2, simply install all blade assemblies 2 on the mounting posts 12, aligning the through holes 21 on the blade assemblies 2. Then, the user can assemble the top cover 3 onto the mounting posts 12, ensuring that the retaining pins 31 on the top cover 3 pass through the through holes 21.

[0030] Next, the user simply pushes the limiting plates 4 on both sides inward to compress the spring 5 and align the side cavity 41 on the limiting plate 4 with the locking cavity 13 on the rotating spindle 11. At this point, the user can continue to press down on the top cover 3, and the locking pin 31 on the top cover 3 will enter the locking cavity 13, and the limiting cavity 311 on the locking pin 31 will align with the movable cavity 14.

[0031] The user then simply needs to release the limiting plates 4 on both sides, and the limiting plates 4 will automatically push outward and reset due to the elastic force of the springs 5. This allows the limiting plates 4 to automatically engage within the limiting cavity 311, thus securing the locking post 31 and the top cover 3. Furthermore, since the top cover 3 is fixed to the top of the blade assembly 2, it also secures the blade assembly 2.

[0032] Furthermore, when the user needs to remove the blade assembly 2, they only need to press and push the limiting plates 4 on both sides inward, so that the side cavity 41 on the limiting plate 4 can move into the locking cavity 13. At this time, the limiting plate 4 is no longer locked to the limiting cavity 311, and the user only needs to remove the top cover 3 upward, and then the blade assembly 2 can be removed.

[0033] Furthermore, the adaptive arrangement between the guide member 141 and the guide groove 42 allows the side cavity 41 to be positioned within the retaining cavity 13 simply by pushing the limiting plate 4 inward to its innermost position. Additionally, when the rotating spindle 11 rotates, the limiting plate 4 moves outward due to centrifugal force, and the adaptive arrangement between the guide member 141 and the guide groove 42 prevents the limiting plate 4 from falling off.

[0034] In this utility model, the locking plate 4 and the locking cavity 311 can be used to fix the locking post 31 and the top cover 3. In this way, the blade assembly 2 can be fixedly assembled by the cooperation between the top cover 3 and the mounting post 12. This method of assembling and disassembling the blade assembly 2 is simple and convenient and easy for users to use.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
