[0021] The utility model embodiments are described below with reference to the drawings in the utility model embodiments.
[0022] The crusher, also known as the stone crusher, is a crushing machine used in the processing of metal and non-metallic minerals, which can crush the mined raw ore into small particles through extrusion and bending action.
[0023] The crusher is mainly divided into jaw crusher, gyratory crusher, cone crusher, roller crusher, hammer crusher and impact crusher according to different crushing methods and working principles. The jaw crusher uses the extrusion and bending action of the two jaw plates to crush hard materials. Its crushing mechanism is composed of fixed jaw plate and movable jaw plate. When the two jaw plates approach, the material is crushed, and when the two jaw plates move away, the material smaller than the discharge port is discharged from the bottom. The jaw crusher is widely used in the industries of mineral processing, building materials, silicate and ceramics due to its simple structure, reliable operation and ability to crush hard materials.
[0024] When the movable jaw plate is installed on the toggle seat 1, it is generally limited and fixed by the occlusion structure formed by the lower limit structure and the wedge block 6 on the upper side, and a lower pressing strip 2 is generally arranged on the lower side. However, the existing lower pressing strip 2 is generally not covered by the movable jaw plate, so the lower pressing strip 2 arranged on the lower side will be gradually worn under the friction of the stone. After wear, it is uneven, so that the movable jaw plate tilts to one side, and the crushing efficiency of the tilted movable jaw plate will decrease significantly, and the wear of the movable jaw plate will increase. Therefore, the lower pressing strip 2 needs to be replaced in time by disassembling the movable jaw plate, and it generally takes more than 3 hours to disassemble the movable jaw plate each time, which will seriously affect the processing efficiency.
[0025] During disassembly, in addition to the wedge block 6 on the upper side which is difficult to disassemble, sometimes due to friction and relatively sealed environment, the air in the weight reduction groove 12 originally expands and escapes after being heated by friction. When the movable jaw plate and the toggle seat 1 cool down, the adsorption effect between the movable jaw plate and the toggle seat 1 is generated, making it more difficult for the movable jaw plate to separate from the toggle seat 1, affecting the disassembly work of the movable jaw plate.
[0026] Therefore, the present application provides a crusher jaw plate assembly. On the one hand, the lower pressing strip 2 is covered by the movable jaw plate, avoiding direct contact between the lower pressing strip 2 and the stone, thereby reducing the wear of the lower pressing strip 2 and the replacement frequency of the lower pressing strip 2, thereby improving the processing efficiency. On the other hand, by arranging the through groove 13 between the weight reduction grooves 12, the adsorption effect between the weight reduction grooves 12 and the toggle seat 1 is reduced, so that the movable jaw plate is more labor-saving and convenient when disassembled, and the efficiency of maintaining the movable jaw plate is improved.
