Technical Field

[0001] This application relates to the technical field of crusher equipment, and particularly relates to a crushing plate for a jaw crusher. Background Art

[0002] The jaw crusher is commonly known as the jaw breaker, also known as the tiger's mouth. It consists of a moving jaw and a stationary jaw, forming a crushing cavity, and is a crusher that simulates the movement of the two jaws of an animal to complete the material crushing operation. It is widely used in various industries such as mining smelting, building materials, highways, railways, water conservancy, and chemical industries for the crushing of various ores and large pieces of materials. The jaw crusher is a common crushing equipment that can crush large stones or other hard materials into smaller particles. The crushing plate is made of wear-resistant alloy steel, which can resist the high-strength impact and friction of the material and maintain long-term stable crushing performance. As one of the important components of the jaw crusher, the crushing plate directly participates in the material crushing process and plays a key role. Selecting a suitable crushing plate can improve the performance of the crusher and ensure that the equipment maintains a stable and efficient working state during long-term use.

[0003] When the existing crushing plate for a jaw crusher crushes materials, the heat generated by crushing friction is likely to cause increased wear and is not convenient for reducing the collision with the side wall during operation. Summary of the Invention

[0004] This application provides a crushing plate for a jaw crusher to solve the problems that when the jaw crusher crushes materials, the heat generated by crushing friction is likely to cause increased wear and is not convenient for reducing the collision with the side wall during operation.

[0014] Considering that when the jaw crusher crushes materials, the heat generated by crushing friction is likely to cause increased wear, and during operation, it is not convenient to reduce the collision with the side wall,

[0015] 1. Through the arrangement of the conveying component, the heat conducting plate, the cooling pipe and the cooler, when the jaw crusher is operating, the heat generated by crushing passes through the crushing plate and is transferred to the cooling pipe through the heat conducting plate. The coolant in the cooling pipe absorbs the heat and enters the water tank. The cooler is used to cool the coolant inside the water tank. At the same time, the water pump is started, and the cooled coolant inside the water tank is transported to the cooling pipe through the connecting pipe for circulating cooling, so as to achieve the effect of cooling the main body of the crushing plate, avoiding accelerated wear caused by too high temperature of the crushing plate, and improving the service life of the crushing plate for the jaw crusher;

[0016] 2. Through the arrangement of the positioning column and the side cutting plate, during installation, the card slot on the back of the main body of the crushing plate is inserted into the corresponding limiting strip, and then the screw passes through the main body of the crushing plate and the push plate, and the fixing nut is twisted for fixation, so as to achieve the effect of positioning and installation. At the same time, during operation, the side cutting plate is closely attached to the side wall of the jaw crusher, reducing the collision with the side wall when the stone is crushed, making the stone move closer to the middle, and improving the safety of the crushing plate for the jaw crusher.
