The left and right sides of the plurality of sliding gears 7 are rotatably connected to the same U-shaped plate 11. A plurality of springs 13 are fixedly connected to the right side of the U-shaped plate 11. The right ends of the plurality of springs 13 are fixedly connected to the inner right side of the hollow plate 12. A moving groove 14 is opened at the top of the hollow plate 12.

A limiting bolt 17 is rotatably connected to the front side of the fixing plate 16;

[0040] Specifically, first, according to the crushing requirements, decide whether to perform coarse crushing or fine crushing and then replace the jaw teeth. At this time, by rotating the second rotating rod 4 on the right side of the hollow plate 12, the fixed gear 5 is driven to rotate. The plurality of fixed gears 5 and the sliding gears 7 are meshed with each other, so that the first rotating rods 3, second rotating rods 4, and third rotating rods 6 on the right side of the frame 1 rotate synchronously, and then drive the rotating plate 8 to rotate, so that the fine jaw teeth 9 and the coarse jaw teeth 10 can change positions by rotating to realize fine crushing or coarse crushing operations. When it is necessary to perform coarse crushing and fine crushing simultaneously, pull the fixing plate 16 to move the U-shaped plate 11 to the right and compress the spring 13. At the same time, rotate the limiting bolt 17 to pass through the corresponding fixing plate 16 and the moving block 15 to limit the U-shaped plate 11. Then rotate the third rotating rod 6 to drive the sliding gear 7 to rotate, and the sliding gear 7 drives the first rotating rod 3 to rotate. At the same time, the upper-middle rotating plate 8 also rotates, prompting the coarse jaw teeth 10 and the fine jaw teeth 9 to exchange positions. At this time, the upper half of the jaw plate is configured with coarse jaw teeth 10, and the lower half is configured with fine jaw teeth 9, so that the jaw plate can perform coarse crushing and fine crushing operations on the raw material simultaneously.

[0041] Refer to Figure 2 and Figure 5, the installation mechanism 2 includes a housing 201, the housing 201 is fixedly connected to the periphery of the frame 1 and the hollow plate 12.

Fixed bolts 206 are rotatably connected to both ends on one side of the plurality of fixed blocks 202;

[0042] Specifically, when performing the installation operation of the jaw plate, first, the limiting block 204 should be fixed at a predetermined position. Subsequently, the plurality of fixed blocks 202 are aligned with the corresponding limiting blocks 204, and the fixed blocks 202 are inserted into the limiting blocks 204. Then, by rotating the fixed bolts 206, they pass through the fixed blocks 202 and enter the corresponding limiting holes 205, thus completing the installation of the jaw plate. When disassembling, only need to rotate the fixed bolts 206 to release the limitation of the fixed blocks 202. The whole process is simple and convenient for the staff to operate.

[0043] Refer to Figure 5 , sliding grooves 18 are opened on the left and right sides inside the plurality of limiting grooves 203. Sliding blocks 19 are fixedly connected to the left and right sides of the plurality of limiting blocks 204. The plurality of sliding blocks 19 slide inside the corresponding sliding grooves 18 respectively. A groove one 20 is opened at the bottom of the housing 201. A rotating shaft 21 is fixedly connected to the bottom of the housing 201. A rotating door 22 is rotatably connected to one side of the rotating shaft 21. A groove two 23 is opened at the bottom of the rotating door 22. A handle 24 is rotatably connected inside the groove two 23;

[0044] Specifically, the sliding grooves 18 and the sliding blocks 19 can make the limiting blocks 204 slide more stably inside the limiting grooves 203. The groove one 20 and the rotating door 22 are used to clean the crushed stones entering the inside of the housing 201. The groove two 23 and the handle 24 facilitate the staff to pull the rotating door 22.

[0045] Refer to Figure 3 and Figure 5 , a plurality of circular rings 25 are equidistantly and fixedly connected to the left and right sides inside the U-shaped plate 11. The plurality of circular rings 25 are respectively rotatably connected to the left and right sides of the corresponding sliding gears 7. One ends of the plurality of fixed bolts 206 penetrate through the fixed blocks 202 and the corresponding limiting holes 205, and the sizes of the fixed bolts 206 and the limiting holes 205 are the same;

[0046] Specifically, the circular rings 25 facilitate the rotation of the sliding gears 7 inside the U-shaped plate 11. The same sizes of the fixed bolts 206 and the limiting holes 205 make the fixed bolts 206 more stable and not easy to shake when performing the limitation.

[0047] Working principle: When using the jaw plate structure of the jaw crusher, it is necessary to replace the jaw teeth according to whether coarse crushing or fine crushing is required for gravel crushing. At this time, rotate the second rotating rod 4 on the right side of the hollow plate 12, so that the second rotating rod 4 drives the fixed gear 5 to rotate. At the same time, multiple fixed gears 5 are engaged with the sliding gear 7. At this time, the first rotating rod 3, the second rotating rod 4 and the third rotating rod 6 on the right side of the frame 1 rotate simultaneously to drive the rotating plate 8 to rotate, so that the fine jaw teeth 9 and the coarse jaw teeth 10 change positions through rotation for fine crushing or coarse crushing. When coarse crushing and fine crushing are required to be carried out simultaneously, at this time, pull the fixed plate 16 to drive the U-shaped plate 11 to move to the right to compress the spring 13. At the same time, rotate the limit bolt 17 to penetrate the corresponding fixed plate 16 and the moving block 15 to limit the U-shaped plate 11. At this time, rotate the third rotating rod 6 to drive the sliding gear 7 to rotate, so that the sliding gear 7 drives the first rotating rod 3 to rotate accordingly. At the same time, the upper-middle rotating plate 8 rotates to drive the coarse jaw teeth 10 and the fine jaw teeth 9 to exchange positions. At this time, the upper half of the jaw plate is the coarse jaw teeth 10 and the lower half is the fine jaw teeth 9, so that the jaw plate can carry out coarse crushing and fine crushing on the raw material at the same time. And when the jaw plate needs to be installed, the limit block 204 needs to be fixed at a predetermined position first. At this time, align multiple fixing blocks 202 with the corresponding limit blocks 204, and at the same time insert the fixing blocks 202 into the limit blocks 204. At this time, rotate the fixing bolt 206 to penetrate the fixing block 202 and the corresponding limit hole 205 to install the jaw plate. When disassembling, just rotate the fixing bolt 206 to cancel the limit on the fixing block 202, and the operation is relatively simple and convenient for the staff to use.

[0048] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
