Abstract
Description
Technical Field
[0001] This utility model relates to crushing tools, and more particularly to a high-efficiency full-space crushing disc. Background Technology
[0002] The traditional crusher disc uses a method where crushing blades are bolted to the disc body, and multiple discs are arranged on a cutter roller. A power system drives the cutter roller to rotate the disc body, and the crushing blades on the rotating disc crush the material entering the crushing chamber. However, currently, the crushing blades of the disc are installed on the outer periphery of the disc body. This means that the crushing blades do not effectively crush materials in the space between adjacent discs. The crushing blades can only break up materials when they move to the outer periphery of each disc, resulting in low crushing efficiency and poor material crushing effect. Furthermore, the crushing blades wear out quickly during crushing, leading to frequent blade replacements and increased production costs. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a high-efficiency full-space crushing disc that can effectively crush materials in the space between adjacent discs of a crusher, improve crushing efficiency, and reduce the frequency of replacement of worn crushing blades.
[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a high-efficiency full-space crushing disc, including a disc body, with a plurality of crushing blades evenly distributed on both sides of the disc body, each crushing blade including a mounting base, the inner end of the mounting base being fixedly connected to the disc body, the outer end of the mounting base extending laterally away from the disc body and having a blade body, and the outer end of the mounting base extending out of the outer periphery of the disc body near the outer periphery of the disc body, with blades provided on the front and rear sides of the blade body respectively.
[0005] As a preferred technical solution, the pulverizing blades located on the same side of the disc body are arranged in at least two layers in a ring from the outer periphery of the disc body to the center. The distance between each pulverizing blade in the same layer and the center of the disc body is the same, and the outer end of the mounting base of the outermost pulverizing blade extends out of the outer periphery of the disc body.
[0006] As a preferred technical solution, the shredders located on the same side of the disc are arranged in a spiral shape from the outer periphery of the disc to the center, and the outer ends of the mounting bases of at least two of the shredders extend out of the outer periphery of the disc.
[0007] As a preferred technical solution, the shredders located on both sides of the disc are centrally symmetrical with the center of the disc as the center of symmetry.
[0008] As a preferred technical solution, the two sides of the disc body are respectively provided with fixing grooves for inserting mounting seats, and fixing bolts that are threadedly connected to the disc body are provided through the mounting seats.
[0009] As a preferred technical solution, the mounting base is provided with a receiving groove for accommodating the head end of the fixing bolt, and the outer surface of the mounting base is not higher than the surface of the disc body.
[0010] The high-efficiency full-space pulverizing disc, employing the aforementioned technical solution, includes a disc body with several pulverizing blades evenly distributed on both sides. Each pulverizing blade includes a mounting base, the inner end of which is fixedly connected to the disc body. The outer end of the mounting base extends laterally away from the disc body, with the blade extending from the outer periphery of the disc body. The outer end of the mounting base near the outer periphery of the disc body extends beyond the outer periphery of the disc body. Each blade has a cutting edge on its front and rear sides. In this invention, pulverizing blades are distributed on both sides of the disc body, with the blades extending outwards. This allows the blades extending from the mounting base to pulverize materials around the outer periphery of the disc body, while the remaining blades effectively pulverize materials within the space between adjacent disc bodies. This achieves effective pulverization of materials throughout the entire space, improving pulverization efficiency and resulting in excellent material pulverization. Furthermore, by providing cutting edges on both the front and rear sides of the blade, when the front blade wears down, only the corresponding two pulverizing blades on each side of the disc body need to be swapped, with the rear blade facing forward. This eliminates the need to replace the blades, reducing the frequency of blade replacement and lowering production costs. Attached Figure Description

[0017] In the description of this utility model, it should be understood that the terms indicating orientation or positional relationship in this utility model are based on the orientation or positional relationship shown in the 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.
[0018] like Figure 1 and 2 As shown, a high-efficiency full-space pulverizing disc includes a disc body 1. Several pulverizing blades 2 are evenly distributed on both sides of the disc body 1. Each pulverizing blade 2 includes a mounting base 3. The inner end of the mounting base 3 is fixedly connected to the disc body 1, and the outer end of the mounting base 3 extends laterally away from the disc body 1, with a blade 4 attached. Thus, the entire pulverizing blade 2 forms an L-shape. The mounting base 3 is fixedly mounted on the side of the disc body 1, and the blade 4 extends laterally for pulverizing materials. Furthermore, the outer end of the mounting base 3 near the outer periphery of the disc body 1 extends beyond the outer periphery of the disc body 1. Therefore, the blades 4 on these mounting bases 3 with their outer ends extending beyond the outer periphery of the disc body 1 are located on the outer side of the disc body 1, used for pulverizing materials around the outer periphery of the disc body 1. The mounting base 3 can be arranged radially along the side of the disc body 1, with the outer end of the mounting base 3 extending radially beyond the outer periphery of the disc body 1 near the outer periphery, while the blade 4 is perpendicular to the mounting base 3 and extends axially along the disc body 1. Blades 5 are respectively provided on the front and rear sides of the blade 4. When using this invention, several crushing discs 1 are evenly arranged and installed on the blade roller. The blades 4 of the crushing blades on adjacent crushing discs intersect each other, so that the crushing between adjacent crushing discs can achieve all-round crushing without dead angles. During operation, the power system drives the blade roller to rotate the disc 1, and the crushing blades 2 on the rotating disc 1 crush the material entering the crushing chamber. When the front blade 5 of the blade 4 wears, the corresponding two crushing blades 2 on both sides of the disc 1 are swapped, so that the rear blade 5 of the blade 4 is installed on the disc 1 with the rear blade 5 facing forward. Figure 1As shown, the pulverizing blades 2 located on the same side of the disc 1 are arranged in at least two layers in a ring shape from the outer periphery of the disc 1 towards the center. The arrangement of the pulverizing blades 2 can be such that each layer has no less than 2 pulverizing blades 2. For example, the pulverizing blades 2 on the same side of the disc 1 can be arranged in 2, 3, 4 or more layers, and the number of pulverizing blades 2 in each layer can be 2, 3, 4 or more. Furthermore, the number of pulverizing blades 2 in the outer layer can be greater than the number of pulverizing blades 2 in the inner layer. In this utility model, the pulverizing blades 2 on the same side of the disc 1 are arranged in 3 layers, with the outermost layer having 4 pulverizing blades 2. The inner two layers each contain two pulverizing blades 2. Each pulverizing blade 2 in the same layer is equidistant from the center of the disc 1. The outermost pulverizing blade 2 has its mounting base 3 extending beyond the outer periphery of the disc 1. In other words, the blade 4 on the outermost pulverizing blade 2's mounting base 3 is located outside the periphery of the disc 1. This arrangement of pulverizing blades 2 on the disc 1, with the blades arranged layer by layer from the outside of the disc 1 towards the center, takes into account the pulverization of all materials on the outer periphery of the disc 1 and between adjacent discs 1, achieving effective pulverization of materials throughout the entire space and improving pulverization efficiency.
[0019] Similarly, Figure 4 As shown, another arrangement of the crushing blades 2 on the disc 1 is illustrated. The crushing blades 2, located on the same side of the disc 1, are arranged in a spiral pattern from the outer periphery of the disc 1 towards the center. At least two of the crushing blades 2 have their mounting bases 3 extending beyond the outer periphery of the disc 1. That is, the blades 4 on the outer ends of the mounting bases 3 extending beyond the outer periphery of the disc 1 are located on the outer side of the disc 1. The number of crushing blades 2 can be determined based on the size of the disc 1 and the actual material to be crushed. In this invention, six crushing blades 2 are used on the same side of the disc 1. This arrangement of the crushing blades 2 on the disc 1, with the blades gradually arranged from the outer side of the disc 1 towards the center, also ensures the crushing of all materials on the outer periphery of the disc 1 and between adjacent discs 1, achieving effective crushing of the material throughout the entire space and improving crushing efficiency. The corresponding crushing blades 2 on both sides of the disc 1 are centrally symmetrical about the center of the disc 1, as shown in the diagram. Figure 4 As shown, this can improve the balance of the cutter head rotation and the uniformity of the force applied during material crushing.
[0020] like Figure 3As shown, the disc body 1 has fixing grooves 6 on both sides for inserting mounting bases 3. Fixing bolts 7, threadedly connected to the disc body 1, pass through the mounting bases 3. The fixing grooves 6 constrain and position the crushing blades 2, while the fixing bolts 7 firmly fix the crushing blades 2 to the disc body 1. The mounting base 3 has a receiving groove 8 for accommodating the head of the fixing bolts 7. The outer surface of the mounting base 3 is not higher than the surface of the disc body 1, reducing the contact between the head of the fixing bolts 7 and the material, and preventing severe wear of the head of the fixing bolts 7, which would make it difficult to disassemble the crushing blades 2. Furthermore, the outer surface of the mounting base 3 is not higher than the surface of the disc body 1, reducing the contact between the mounting base 3 and the material, and reducing wear.
[0021] like Figure 1 and 4 As shown, in use, multiple discs 1 are fixedly mounted on the crusher's blade roller through shaft holes 9. The discs 1 are evenly spaced on the blade roller, and the blades 4 of the crushing blades on adjacent crushing discs are arranged in a crisscross pattern to ensure all-around crushing without dead angles. During operation, the crusher drives the blade roller to rotate the discs 1. The blades 4 located on the outer periphery of the discs 1 crush the material around the outer periphery of the discs 1, while the blades 4 located on the sides of the discs 1 crush the material in the space between adjacent discs 1. After the blades 5 of the blades 4 wear down, the fixing bolts 7 are removed and the corresponding two crushing blades 2 on both sides of the discs 1 are swapped, so that the rear blades 5 of the swapped blades 4 face forward.
