[0015] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.
[0016] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not 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. Furthermore, the terms "first," "second," etc., 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, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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; and 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. Example:
[0018] This utility model provides a replaceable crushing tooth ring for crushing materials inside a crusher. Each tooth can be replaced individually based on wear during operation, effectively reducing maintenance costs and maintaining the equipment in normal working condition. To achieve this cost-saving effect, the device includes a positioning outer ring 1, such as... Figure 1As shown, the positioning outer ring 1 is a hollow column with multiple positioning grooves around its circumference. Each positioning groove contains a detachable tooth 2, allowing the corresponding tooth to be installed or removed. To facilitate the fixing of the detachable tooth 2 and to utilize its breaking structure function, the detachable tooth 2 may include an abutment plate 201. Figure 1 and Figure 2 As shown, a protruding tooth 202 is installed on one side of the abutment plate 201, which can penetrate the positioning groove and protrude from the inner wall of the positioning outer ring 1. The protruding tooth 202 is designed to crush the material by mutual compression with the toothed part inside the crusher. In order to ensure the stable fixation of the abutment plate 201 and avoid instability of the protruding tooth 202 structure, the side of the abutment plate 201 facing the protruding tooth 202 is set as an arc surface that can match the outer surface of the positioning outer ring 1. This is to ensure accurate fitting of the connection part. To prevent the detachable tooth 2 from being positioned outside the outer ring 1, the abutment plate 201 is designed with the arc surface that can match the outer surface of the positioning outer ring 1. To prevent loosening of ring 1, a beveled guide block 203 is provided on the other side of the abutment plate 201. Finally, a locking ring 3 is fitted around the outer ring of the positioning outer ring 1. The inner diameter of the locking ring 3 is larger than the outer diameter of the positioning outer ring 1 so that it can fit around the outer ring of the multiple removable teeth 2. Preferably, the inner diameter of the locking ring 3 should be slightly larger than the maximum outer diameter formed by the multiple guide blocks 203, so that when the locking ring 3 is pressed down, it can simultaneously press against the outer side of the multiple guide blocks 203, thereby providing corresponding compressive stress to the corresponding removable teeth 2. In some embodiments, multiple protruding teeth 202 can be installed on an abutment plate 201, which can reduce the complexity of the structure and facilitate assembly.
[0019] This utility model provides a replaceable crushing tooth ring. Considering that in some conical crushers, the convex teeth 202 may need to be distributed in a conical form, preferably, the side of the convex teeth 202 closest to the center line of the positioning outer ring 1 can be configured as an inclined surface, such as... Figure 4 As shown, the inclined surface of the protruding tooth 202 intersects with the center line of the positioning outer ring 1, thus forming a corresponding conical structure to achieve crushing. In some other crushing methods, to facilitate providing more diverse crushing actions, adjacent protruding teeth 202 can be configured to protrude from the inner ring of the positioning outer ring 1 at different depths. By configuring different protrusion depths, the material can avoid being acted on only at the tooth surface position, and can also be crushed by corresponding impact force or extrusion, which helps to adapt to crushing other different types of materials. The replaceable structure utilizes a free configuration method, allowing different protruding tooth 202 structural parts to be replaced according to material needs, thereby meeting various crushing requirements.
[0020] This utility model embodiment provides a replaceable breakable toothed ring. To facilitate the installation and disassembly of the locking ring 3, and thus the installation and disassembly of the detachable tooth 2, the locking ring 3 can be configured to be composed of at least two annular plates spliced together. (Refer to...) Figure 1 As shown, each annular plate has flanges on both sides. The flanges of two adjacent annular plates are connected by the first bolt 11 to form a stable ring structure to cover the outer ring of multiple detachable teeth 2. The design of the first bolt 11 also allows the locking ring 3 to shrink its inner diameter, thereby stably pressing the multiple detachable teeth 2.
[0021] This utility model embodiment provides a replaceable breakable toothed ring. When locking multiple detachable teeth 2 using the locking ring 3, it is difficult to apply sufficient pressure manually to ensure that it is fitted onto the outermost side of the guide block 203. At this time, if... Figure 1 and Figure 2 As shown, a protruding flange is provided on one side of the positioning outer ring 1. A second bolt 6 is fixedly installed on the flange of the positioning outer ring 1. The extension direction of the second bolt 6 is parallel to the center line direction of the positioning outer ring 1. At the same time, a flap 7 is fixedly installed at the outer ring position of the locking ring 3, and the flap 7 is provided with an adjustment hole for the second bolt 6 to pass through. Finally, according to... Figure 1 As shown in the diagram, the second bolt 6 is threaded with an adjusting nut 8 that acts on the flap 7. The locking action of the adjusting nut 8 drives the locking ring 3 to move up and down, providing sufficient pressure or thrust to tighten or loosen the locking ring 3. To improve the uniformity of force and prevent one side from tilting too high and making the other side difficult to move, at least two flaps 7 and second bolts 6 can be arranged in a circular array, evenly distributed on the side of the positioning outer ring 1. Multiple sets of controls are used to stabilize the applied force. To prevent excessive local tilting and offset, a positioning block 10 can be provided on the outer periphery of the locking ring 3. A guide rod 9, which passes through the positioning block 10, is also provided on the flange of the positioning outer ring 1 to guide the movement of the locking ring 3, thus preventing excessive local offset.
[0022] This utility model provides a replaceable broken toothed ring. In some other embodiments, considering that when replacing the removable teeth 2, usually only one by one needs to be replaced, directly removing the locking ring 3 may cause multiple removable teeth 2 to loosen simultaneously. To facilitate access and maintain the stable placement of other removable teeth 2, a notch with a width greater than the width of the removable tooth 2 is provided on the locking ring 3. The width of this notch is configured to be less than the farthest distance between two adjacent removable teeth 2. By rotating the locking ring 3, the notch and the corresponding removable tooth 2 can be aligned, thereby allowing the damaged removable tooth 2 to be removed. In this embodiment, the locking ring 3 can be moved out from the notch without affecting the positioning of other detachable teeth 2. In this embodiment, the locking ring 3 can be rotated and set outside the positioning outer ring 1. The corresponding detachable teeth 2 are locked by rotation. When it is not necessary to remove it, the notch can be moved to a position that does not correspond to the detachable teeth 2. In some other preferred embodiments, in order to avoid the stress on the locking ring 3 being unstable due to the notch position, a cover plate 4 can be installed at the notch position of the locking ring 3. The inner arc surface of the cover plate 4 and the inner arc surface of the locking ring 3 can be located on the same cylindrical surface.
[0023] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
