[0002] Jaw crushers are widely used in industries such as mining, metallurgy, building materials, highways, railways, water conservancy, and chemicals. The jaw plates are the main components of a jaw crusher, generally made of high-manganese steel, and have a toothed structure. The crushing function is achieved through the interaction of the teeth on the jaw plates.

[0003] The stress concentration part of the existing jaw plate is mostly the jaw plate rack. The rack bears huge crushing force and friction from the material. When the rack wears and breaks, maintenance requires replacing the entire jaw plate, resulting in high maintenance costs. In addition, during the rack crushing operation, due to the reciprocating motion of the movable jaw plate, the material being crushed is prone to slippage between the fixed jaw plate and the vertical rack teeth, affecting crushing efficiency. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a point-type crushing jaw plate device and its crusher.

[0006] Furthermore, the dotted tooth structure consists of multiple independent protruding tooth points, which are arranged in a matrix or staggered arrangement on the surfaces of the moving jaw tooth plate and the fixed jaw tooth plate.

[0007] Furthermore, the dot-shaped teeth are quadrangular pyramidal protrusions with a tooth tip diameter of 8-15 mm, a tooth height of 1.2-1.8 times the tooth tip diameter, and a center distance between adjacent teeth of 2-3 times the tooth tip diameter.

[0008] Furthermore, a first snap-fit ​​assembly is provided between the movable jaw base plate and the movable jaw tooth plate. The first snap-fit ​​assembly includes a first buckle and a first slot that matches the first buckle. The first buckle is fixedly installed on the movable jaw base plate, and the first slot is formed on the movable jaw tooth plate.

[0009] Furthermore, a second snap-fit ​​assembly is provided between the fixed jaw base plate and the fixed jaw tooth plate. The second snap-fit ​​assembly includes a second buckle and a second slot that matches the second buckle. The second buckle is fixedly installed on the fixed jaw base plate, and the second slot is formed on the fixed jaw tooth plate.

[0010] Furthermore, the movable jaw plate is provided with a first insertion assembly, which includes a first insert extending along the mating direction of two adjacent movable jaw plates on one side of the movable jaw plate and a first slot on the other side of the movable jaw plate for insertion with the first insert on the adjacent movable jaw plate; the first slot is flared, and the first insert is adapted to the first slot.

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0018] Reference Figures 1-5 As shown in the preferred embodiment of this utility model, a point-shaped crushing jaw plate device includes a movable jaw plate assembly and a fixed jaw plate assembly. The movable jaw plate assembly includes a movable jaw base plate 1 and a plurality of mutually spliced ​​movable jaw tooth plates 2 detachably connected to the movable jaw base plate 1. The fixed jaw plate assembly includes a fixed jaw base plate 3 and a plurality of mutually spliced ​​fixed jaw tooth plates 4 detachably connected to the fixed jaw base plate 3. This allows the fixed jaw plate and the movable jaw plate to be interchanged or swapped up and down, making full use of every tooth of the jaw plate and extending the service life of the jaw plate. The movable jaw tooth plates 2 and the fixed jaw tooth plates 4 are provided with point-shaped tooth structures 9 on their crushing working surfaces, which can improve the crushing efficiency. Because the contact area between the point-shaped teeth and the crushed object is small, the force per unit area is greater and it is not easy to slip.

[0019] As a preferred embodiment of this utility model, it may also have the following additional technical features: the dotted tooth structure 9 is composed of multiple independently protruding tooth points, which are arranged in a matrix or staggered arrangement on the surfaces of the moving jaw tooth plate 2 and the fixed jaw tooth plate 4; and the dotted teeth are quadrangular pyramidal protrusions with a tooth tip diameter of 8-15mm, a tooth height of 1.2-1.8 times the tooth tip diameter, and a center distance between adjacent teeth of 2-3 times the tooth tip diameter. This makes it easier to crush the object to be crushed because the contact area between the tooth and the object is small, resulting in greater force per unit area and less slippage, thereby accelerating the crushing rate.

[0020] In this embodiment, a first engaging assembly 5 is provided between the movable jaw base plate 1 and the movable jaw tooth plate 2. The first engaging assembly 5 includes a first latch 501 and a first slot 502 that matches the first latch 501. The first latch 501 is fixedly installed on the movable jaw base plate 1, and the first slot 502 is formed on the movable jaw tooth plate 2. Therefore, when the point-like teeth of the movable jaw tooth plate wear, only the corresponding worn tooth plate needs to be replaced, without replacing the entire jaw plate, thus reducing the maintenance cost of the jaw plate. In this embodiment, a second snap-fit ​​assembly 6 is provided between the fixed jaw base plate 3 and the fixed jaw tooth plate 4. The second snap-fit ​​assembly 6 includes a second snap fastener 601 and a second slot 602 that matches the second snap fastener 601. The second snap fastener 601 is fixedly installed on the fixed jaw base plate 3, and the second slot 602 is formed on the fixed jaw tooth plate 4. Therefore, when the point-like teeth of the fixed jaw base plate wear, only the corresponding worn tooth plate needs to be replaced, without replacing the entire jaw plate, thus reducing the maintenance cost of the jaw plate.

[0021] In this embodiment, the movable jaw plate 2 is provided with a first insertion assembly 7. The first insertion assembly 7 includes a first insert 701 extending along the mating direction of two adjacent movable jaw plates on one side of the movable jaw plate 2, and a first slot 702 on the other side of the movable jaw plate 2 for insertion with the first insert 701 on the adjacent movable jaw plate. The first slot 701 is flared, and the first insert 701 is adapted to the first slot 701. This allows the movable jaw plates 2 to be interconnected, making the jaw plates formed by the movable jaw plates 2, which are detachably mounted on the base plate, more stable during material crushing, thus ensuring the crushing effect.

[0022] In this embodiment, the fixed jaw plate 4 is provided with a second insertion assembly 8. The second insertion assembly 8 includes a second insert 801 extending along the mating direction of two adjacent fixed jaw plates on one side of the fixed jaw plate 4, and a second slot 802 on the other side of the fixed jaw plate 4 for insertion with the second insert on the adjacent fixed jaw plate. The second slot 802 is flared, and the second insert 801 is adapted to the second slot 802. This allows the fixed jaw plates 4 to be interconnected, making the jaw plates formed by the fixed jaw plates 4, which are detachably mounted on the base plate, more stable during material crushing, thus ensuring the crushing effect.

[0023] In order to make the fixed jaw plate and the movable jaw plate interchangeable and interchangeable, to make full use of every tooth of the jaw plate and extend the service life of the jaw plate, the first snap-fit ​​component 5 and the second snap-fit ​​component 6 of this application have the same structure; the first plug-in component 7 and the second plug-in component 8 also have the same structure.

[0024] In this embodiment, the movable jaw plate 2 and the fixed jaw plate 4 are provided with a porous honeycomb structure on the side away from the dotted tooth structure. This disperses the force during the crushing process and prevents the movable jaw plate 2 and the fixed jaw plate 4 from breaking due to concentrated force.

[0025] A crusher is equipped with the aforementioned jaw plate device, which allows the fixed jaw plate and the movable jaw plate to be interchanged or swapped up and down, making full use of every tooth of the jaw plate, extending the service life of the jaw plate, and effectively reducing production costs.

[0026] Without causing conflict, those skilled in the art can freely combine and use the above-mentioned additional technical features.
