Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0020] During specific implementation: As Figures 1-5 shown, a gap adjusting device for a jaw crusher includes: a frame 1, on one side of the inner wall of the frame 1, a mounting block 101 is fixedly connected, on the other side of the mounting block 101, a mounting plate 102 is provided, on the other side of the mounting plate 102, a fixed jaw plate 103 is provided, on the surface of the mounting block 101, two mounting seats 104 are fixedly connected and symmetrically distributed, on the inner side of the mounting plate 102, two hinge rods are fixedly connected and symmetrically distributed, and the other end of the hinge rod is rotatably connected to the inner wall of the adjacent mounting seat 104; an adjusting mechanism 2, the adjusting mechanism 2 includes an adjusting component 21 and a replacement component 22, the adjusting component 21 is used for quickly adjusting the position of the mounting plate 102, and the replacement component 22 is used for replacing the fixed jaw plate 103.
[0021] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the adjusting component 21 includes a chute 211 opened on the surface of the frame 1, a fixed rod 215 is slidably connected to the inner wall of the chute 211, one end of the fixed rod 215 penetrates out of the chute 211 and is fixedly connected to the surface of the mounting plate 102, the other end of the fixed rod 215 penetrates out of the chute 211 and is provided with a dial block 213, a limiting rod 217 is fixedly connected to the surface of the dial block 213, uniformly distributed limiting holes 212 are opened on the surface of the frame 1, the other end of the limiting rod 217 extends into the interior of the adjacent limiting hole 212, a guiding sliding plate 216 is fixedly connected to the surface of the fixed rod 215, the guiding sliding plate 216 is slidably connected to the inner wall of the frame 1, a sliding rod 214 is fixedly connected to one side of the dial block 213 close to the fixed rod 215, the other end of the sliding rod 214 penetrates the fixed rod 215 and is slidably connected to the inner wall of the fixed rod 215, a spring 218 is fixedly connected to the surface of the sliding rod 214, and the other end of the spring 218 is fixedly connected to the inner wall of the fixed rod 215;
[0022] By pulling the shifting block 213 away from the frame 1, the sliding rod 214 can be driven to compress the spring 218 during this process, and at the same time, the limiting rod 217 can be driven to separate from the limiting hole 212, thus the limiting effect on the fixing rod 215 can be released. During this process, the mounting plate 102 can be driven by the fixing rod 215 to slide along the inner wall of the sliding groove 211 with the hinge rod as the center. At the same time, the guiding sliding plate 216 can make the fixing rod 215 more stable during the moving process, and thus the gap between the fixed jaw plate 103 and the moving jaw plate can be changed. The moving jaw plate is a conventional technical means of this device and an essential structure, so no more details are described here.
[0023] As Figure 1 , Figure 2 and Figure 4 shown, the replacement component 22 includes two connection blocks 222 fixedly connected to one side of the fixed jaw plate 103 and symmetrically distributed. An installation groove corresponding to the connection block 222 is provided on the side of the mounting plate 102 close to the fixed jaw plate 103. A threaded rod 221 is fixedly connected to the inner bottom wall of the installation groove. The upper end of the threaded rod 221 penetrates through the connection block 222. A fastening nut 223 is arranged on the top of the connection block 222. The bottom surface of the fastening nut 223 is attached to the top surface of the connection block 222, and the fastening nut 223 is threadedly connected to the threaded rod 221;
[0024] By disassembling the connection between the fastening nut 223 and the threaded rod 221, the limitation on the connection block 222 can be released, and thus the fixed jaw plate 103 can be taken out along the inner wall of the installation groove through the connection block 222, so as to facilitate the replacement of the fixed jaw plate 103 with different thicknesses. Cooperating with the adjusting component 21, a larger gap can be adjusted.
[0025] When the utility model is in use, by pulling the shifting block 213 away from the frame 1, the sliding rod 214 can be driven to compress the spring 218 during this process, and at the same time, the limiting rod 217 can be driven to separate from the limiting hole 212, thus the limiting effect on the fixing rod 215 can be released. During this process, the mounting plate 102 can be driven by the fixing rod 215 to slide along the inner wall of the sliding groove 211 with the hinge rod as the center. At the same time, the guiding sliding plate 216 can make the fixing rod 215 more stable during the moving process, and thus the gap between the fixed jaw plate 103 and the moving jaw plate can be changed. With the setting of the replacement component 22, the fixed jaw plate 103 with different thicknesses can be replaced, and cooperating with the adjusting component 21, a larger gap can be adjusted.
[0026] In addition, it should be understood that although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
