[0002] Jaw crushers are often used in the crushing of various ores and bulk materials in industries such as mining and smelting, building materials, roads, railways, water conservancy and chemical industry, and have high crushing efficiency. Jaw crushers usually include two jaw plates, a movable jaw and a static jaw, which form a crushing chamber. When the machine is running, the movable jaw moves back and forth towards or away from the static jaw, thereby crushing the materials in the crushing chamber.

[0003] The jaw plate of the existing jaw crusher usually needs to be processed in order to improve the crushing efficiency, such as processing grooves to form spaced raised crushing parts, grinding the crushing surface to avoid material jamming, etc. Therefore, in order to make the jaw plate have certain machining properties, it is usually made of steel, such as high-strength steel, cast steel, etc. However, since jaw crushers are often used to crush materials with high hardness such as ore, steel is easily worn under the action of ore, which makes its processing effect worse, and even has the hidden danger of material jamming, which affects the service life of the jaw plate.

[0004] Therefore, it is urgent for those skilled in the art to provide a jaw plate that can meet machining performance requirements and has high wear resistance to ensure its service life. Summary of the invention

[0026] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] See also Figures 1 to 4 The embodiment of the utility model provides a jaw plate suitable for a jaw crusher, comprising a plate body 1 and a crushing part 2 fixedly connected to the plate body 1.

[0030] Specifically, in the present embodiment, in order to increase the crushing efficiency of the jaw plate, in the present embodiment, a plurality of crushing parts 2 are arranged at intervals and protrude from the end surface of the plate body 1, so that a sink 3 is formed between the plurality of crushing parts 2, so that when the crushing part 2 hits the material, the material area corresponding to the sink 3 will not collide with the material, thereby reducing the contact area between the material and the jaw plate, facilitating the downward movement of the crushed material, and the contact area between the material and the crushing part 2 is smaller than that between the material and the plate surface of the plate body 1, which is more conducive to the crushing of the material.

[0031] Since the jaw plate is usually formed into its specific structure (such as the crushing part 2 and the sink 3) by machining a plate, the jaw plate needs to have a certain machining performance, and the increase in the jaw plate machining performance will affect the wear resistance of the jaw plate to a certain extent, thereby affecting the service life of the jaw plate. Therefore, in order to improve the machining performance and wear resistance of the jaw plate, so that it is easy to process without affecting its service life, in this embodiment, each crushing part 2 is fixed with a wear-resistant part 4, and the wear resistance of the wear-resistant part 4 is greater than that of the crushing part 2.

[0032] Specifically, the crushing part 2 is made of steel; and the wear-resistant part 4 is made of ceramic particle blocks.

[0033] The wear-resistant part 4 can be set to a variety of structures, which can be exposed after the crushing part 2 is worn and contact with the material.

[0034] See also Figure 1 and Figure 2 In this embodiment, in order to increase the contact area between the wear-resistant part 4 and the material, the wear-resistant part 4 is set to be plate-shaped and has a relatively parallel first plane 41 and a second plane 42. The distance H1 between the first plane 41 and the second plane 42 can be set to 10 mm, 15 mm or 20 mm, so that the wear-resistant part 4 has a certain thickness. Of course, the value range of H1 satisfies 10 to 20 mm to meet the wear resistance requirements of the jaw plate, thereby extending the service life of the jaw plate.

[0035] Furthermore, in order to increase the stable installation of the wear-resistant part 4 and allow the crushing part 2 to have a certain wear space, the crushing part 2 has a crushing surface 20, and the crushing surface 20 and the first plane 41 are parallel to the end surface of the plate body 1; the first plane 41 is located on the side of the second plane 42 close to the crushing surface 20, and the distance H2 between the first plane 41 and the crushing surface 20 is in the range of 20 to 25 mm.

[0036] Furthermore, in order to increase the pressure of the crushing surface 20 on the material, increase the material crushing effect, and facilitate the crushed material to escape from the crushing surface 20, the edge of the crushing surface 20 is in an arc shape.

[0037] See also Figure 3 and Figure 4 Since the ceramic particle block is usually an integrated block structure, in order to increase the stability of its installation with the crushing part 2 and prevent the wear-resistant part 4 from falling off during the collision with the material, the crushing part 2 is formed by casting and solidifying molten steel; at least two wear-resistant parts 4 are provided on the same crushing part 2, and a casting interval 5 for accommodating molten steel so that the molten steel is solidified to form steel is formed between adjacent wear-resistant parts 4, so that the molten steel is filled in the casting interval 5 and forms a part of the crushing part 2 after solidification, thereby increasing the contact area between the wear-resistant part 4 and the crushing part 2 and increasing the stability of the installation of the wear-resistant part 4.

[0038] Furthermore, in this embodiment, the ratio of the maximum width W1 of the casting interval 5 to the maximum length L1 of the wear-resistant part 4 can be set to 0.2, 0.25 or 0.3, so that the crushing part 2 within the casting interval 5 can be stably connected to the wear-resistant part 4. Of course, when the ratio of the maximum width W1 of the casting interval 5 to the maximum length L1 of the wear-resistant part 4 is in the range of 0.2 to 0.3, the effect of stable installation of the wear-resistant part 4 can also be achieved.

[0039] Of course, in other embodiments, the maximum width W1 of the casting spacing 5 and the maximum length L1 of the wear-resistant part 4 can be set according to actual usage conditions, so as to achieve a stable connection between the wear-resistant part 4 and the crushing part 2. For example, the maximum width W1 of the casting spacing 5 can be set to 25 mm, 27.5 mm or 30 mm, and the value range of W1 is 25 to 30 mm. The maximum length L1 of the wear-resistant part 4 can be in the range of 110 mm, 115 mm or 120 mm, and the value range of L1 can be 110 to 120 mm.

[0040] In order to increase the wear resistance of the jaw plate and thus increase its service life, in the present embodiment, the ratio of the projection area of ​​the wear-resistant part 4 on the same crushing part 2 on the end surface of the plate body 1 to the projection area of ​​the corresponding crushing part 2 on the end surface of the plate body 1 is 0.8. Of course, the ratio of the projection area of ​​the wear-resistant part 4 on the same crushing part 2 on the end surface of the plate body 1 to the projection area of ​​the corresponding crushing part 2 on the end surface of the plate body 1 is in the range of 0.6 to 0.85, which can make the contact area between the wear-resistant part 4 and the material large enough to increase the service life of the jaw plate.

[0041] See also Figure 3 and Figure 4 In order to facilitate the feeding and discharging of the jaw plate, in the present embodiment, the jaw plate further includes a plurality of material guide portions 6 arranged at intervals, the material guide portions 6 are fixedly connected to the plate body 1 and protrude from the end surface of the plate body 1; along the length direction of the plate body 1, the plurality of material guide portions 6 are symmetrically arranged at both ends of the crushing portion.

[0042] Furthermore, the thickness of the material guiding portion 6 gradually decreases from the crushing portion 2 toward both ends of the plate body 1 in the length direction to form a guiding inclined surface 61 .

[0043] In order to facilitate the processing of the jaw plate and increase the crushing effect of the jaw plate, in this embodiment, a plurality of crushing parts 2 are distributed in a linear array at least along the length direction of the plate body 1; and the wear-resistant parts 4 located on the same crushing part 2 are distributed in a linear array along the length direction of the plate body 1.

[0044] Furthermore, the crushing portion 2 includes a middle crushing block 21 and an edge crushing block 22; along the two side edges in the width direction of the plate body 1, the edge crushing blocks 22 are symmetrically distributed on the two side edges of the middle crushing block 21; the length L22 of the edge crushing block 22 is greater than the length L21 of the middle crushing block 21.

[0045] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
