Technical Field

[0001] The utility model relates to the technical field of fixed jaw plates, in particular to a fixed jaw plate used for a heavy jaw crusher. Background Art

[0002] The jaw crusher is composed of two jaw plates, the movable jaw and the fixed jaw, which form a crushing chamber and simulate the movement of the two jaws of animals to complete the material crushing operation. When the jaw crusher is working, the jaw plate is the first to be worn. When the material enters the crushing chamber, the movable jaw plate is squeezed and the material will be subjected to strong cutting action.

[0003] After searching, research and analysis, it was found that the fixed jaw plate of the jaw crusher still has the following shortcomings to a certain extent.

[0004] For example, the fixed jaw plate is easy to wear during crushing, and is connected to the crusher body by bolts. The fixed jaw plate is thick and heavy, so it is very inconvenient to replace, disassemble and install. In addition, the main wear parts of the fixed jaw plate are concentrated in the lower part. Each replacement requires the replacement of the entire fixed jaw plate, causing great waste. In order to solve the above technical problems, we have designed a fixed jaw plate for heavy-duty jaw crusher. Utility Model Content

The right end of the anchor rod passes through the fixed jaw fixed plate and the sub-jaw plate in sequence, a pull plate is slidably clamped on the right side of the surface of the fixed jaw fixed plate, a spring 1 is fixedly connected to the top of the pull plate, and the top of the spring 1 is fixedly connected to the surface of the fixed jaw fixed plate, a clamping plate is welded to the bottom of the pull plate, and the bottom end of the clamping plate passes through the fixed jaw fixed plate and is clamped on the surface of the right end of the anchor rod.

[0007] Preferably, the limiting mechanism includes four short plates, which are respectively fixed at the four corners of the top of the fixed jaw fixing plate, and the opposite sides of the two short plates on both sides are fixedly connected with a connecting rod, the surface sliding sleeve at the front end of the connecting rod is provided with a limiting plate, and the surface movable sleeve at the rear end of the connecting rod is provided with a spring 2, and the two ends of the spring 2 are respectively fixedly connected to the short plate and one side of the limiting plate.

[0008] Preferably, the top of the limit plate is rotatably connected to a fastener via a rotating shaft, and a positioning rod is welded to the rear side of the top of the fixed jaw fixing plate.

[0009] Preferably, a docking groove matched with the sub-jaw plates is opened on the front side of the fixed jaw fixed plate, and a plurality of sub-jaw plates are combined into a complete fixed jaw plate.

[0010] Preferably, the surface of the right end of the anchor rod is provided with an annular groove matched with the clamping plate, and the right end of the anchor rod is chamfered.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model moves the limit plate by pulling the fastener, and the movement of the limit plate compresses the spring 2, and then the fastener is put on the surface of the positioning rod to expose the upper part of the docking groove, and then the sub-jaw plate is docked in the docking groove on the fixed jaw fixing plate, and then the fastener is separated from the positioning rod, and under the action of the rebound of the spring 2, the limit plate limits the upper part of the topmost sub-jaw plate, and the anchor rod passes through the fixed jaw fixing plate and the sub-jaw plate, and the right end of the anchor rod squeezes the clamping plate to move the clamping plate and the pull plate up, and the spring 1 is compressed. With continuous insertion, the lower end of the clamping plate is inserted into the annular clamping groove, thereby having the advantage of being able to quickly install the sub-jaw plate, and it is also convenient to disassemble.

[0013] 2. The utility model can replace the lower sub-jaw plate to the upper part by adjusting the position of the sub-jaw plate on the fixed jaw fixed plate. Since the main wear parts of the jaw plate are concentrated in the lower part, it is avoided that the entire fixed jaw plate needs to be replaced every time, thereby reducing waste. The position of the sub-jaw plate replacement can be adjusted according to actual conditions to improve utilization and reduce the cost of consumables. BRIEF DESCRIPTION OF THE DRAWINGS
