Technical Field

[0001] This utility model belongs to the technical field of crusher accessories, and in particular relates to a new type of jaw plate for crushers. Background Technology

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

[0003] The utility model disclosed in the existing announcement number CN218422969U is a jaw plate for a crusher, including a base plate and a jaw plate body installed on the base plate. The jaw plate body is composed of multiple body units that can be detachably installed on the base plate. Each body unit includes a jaw plate and multiple wear-resistant protrusions disposed on the jaw plate.

[0004] The jaw plate of the aforementioned crusher is connected to the base plate by multiple bolts, which require each bolt to be screwed into the threaded hole one by one. This makes the installation and disassembly of the jaw plate quite troublesome and cumbersome. Therefore, we provide a new type of jaw plate for crushers. Utility Model Content

[0007] The present invention is further configured such that the disassembly assembly includes a plurality of dovetail grooves, the dovetail grooves have a recess first inside, the dovetail grooves are connected to the recess first, a limit plate first is slidably arranged inside the recess first, and a limit block for mutual cooperation is fixedly connected inside the dovetail block.

[0008] The present invention is further configured such that a limiting rod is slidably connected inside the first groove, the limiting rod passes through the first groove, the top end of the limiting rod is fixedly connected to the bottom of the first limiting plate, a spring is sleeved on the outer wall of the limiting rod, one end of the spring is fixedly connected to the inner bottom surface of the first groove, and a circular rod is slidably provided at the bottom of the limiting rod.

[0009] The present invention is further configured such that a through groove is provided inside the first groove to cooperate with the limiting rod, a guide rod is fixedly connected inside the through groove, and a vertical groove and an arc groove are respectively provided on the outer wall of the circular rod to cooperate with the guide rod, and the vertical groove and the arc groove are interconnected.

[0010] The present invention is further configured such that the limiting rod is rotatably connected to the circular rod, and each dovetail block has a groove on its lower surface that is used in conjunction with the limiting block.

[0011] The present invention is further configured such that the dovetail groove gradually narrows from one end to the other.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model divides the toothed plate into multiple pieces. When one of the toothed plates is damaged, only the damaged toothed plate needs to be replaced, without replacing the entire toothed plate. At the same time, a disassembly component is set between the toothed plate and the base plate, which can greatly improve the installation efficiency of the toothed plate and the base plate and save the installation time of the toothed plate.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] For a specific implementation example, please refer to Implementation Example 1. Figure 1-6 This utility model is a new type of jaw plate for a crusher, including a base plate 1; specifically, a plurality of toothed plates 2 are slidably arranged on the upper surface of the base plate 1, and a dovetail block 3 is fixedly connected to the bottom of each toothed plate 2. A disassembly assembly for use with the dovetail block 3 is provided on the upper surface of the base plate 1. The disassembly assembly includes a plurality of dovetail grooves 101. A groove 102 is provided inside the dovetail groove 101. The dovetail groove 101 and the groove 102 are connected. A limit plate 103 is slidably arranged inside the groove 102. A limit block 302 for use with 13 is fixedly connected inside the dovetail block 3.

[0026] Furthermore, a limiting rod 104 is slidably connected inside the groove 102. The limiting rod 104 passes through the groove 102. The top end of the limiting rod 104 is fixedly connected to the bottom of the limiting plate 103. A spring 105 is sleeved on the outer wall of the limiting rod 104. One end of the spring 105 is fixedly connected to the inner bottom surface of the groove 102. A circular rod 106 is slidably provided at the bottom of the limiting rod 104.

[0027] Furthermore, the interior of the groove 102 is provided with a through groove that cooperates with the limiting rod 104. A guide rod 107 is fixedly connected inside the through groove. The outer wall of the circular rod 106 is provided with a vertical groove 108 and an arc groove 109 that cooperate with the guide rod 107. The vertical groove 108 and the arc groove 109 are interconnected.

[0028] Furthermore, the limiting rod 104 is rotatably connected to the circular rod 106, and each dovetail block 3 has a groove 301 on its lower surface that is used in conjunction with the limiting block 302.

[0029] Furthermore, the dovetail groove 101 gradually narrows from one end to the other.

[0030] The operation process of this embodiment is as follows: When the toothed plate 2 needs to be installed, the dovetail block 3 at the bottom of the toothed plate 2 is engaged into the dovetail groove 101 on the upper surface of the base plate 1. Since the dovetail groove 101 gradually narrows, it plays a preliminary limiting role for the dovetail block 3. During the movement of the dovetail block 3, the bottom limiting block 302 contacts the limiting plate 103, causing the limiting plate 103 to move down into the groove 102 inside the base plate 1. When the dovetail groove 101 and the dovetail block 3 are engaged, the spring 105 pushes the limiting plate 103 up and engages with the limiting block 302 inside the dovetail block 3. At this time, the dovetail block 3 cannot move. When the toothed plate 2 and the base plate 1 are installed, and the toothed plate 2 needs to be disassembled, the circular rod 106 is pulled. The vertical groove 108 on the outer wall of the circular rod 106 moves along the guide rod 107 in the through groove. The circular rod 106 drives the limiting plate 103 to move downward. When it moves to the intersection of the vertical groove 108 and the arc groove 109, the circular rod 106 is rotated. At this time, the limiting plate 103 completes the limiting and is released from the restriction of the limiting block 302. The toothed plate 2 is pushed and the dovetail block 3 is pulled out from the dovetail groove 101. At this time, the toothed plate 2 can be disassembled quickly, which improves the efficiency of the toothed plate 2 during installation and replacement.
