[0021] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0022] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0023] This embodiment mainly describes the wear-resistant tooth plate made of high-manganese steel based on high-chromium cast iron inlaid ceramic particles, as detailed below:

[0024] like Figure 1 , Figure 2 As shown, the wear-resistant toothed plate of high manganese steel based on high chromium cast iron inlaid with ceramic particles is used in this embodiment. The toothed plate is installed on the crusher, including a frame 1 and a guard plate 3. Specifically, a motor 2 is installed on the frame 1, and there are two guard plates 3. The two guard plates 3 are symmetrically arranged on both sides of the frame 1 and fixed on the frame 1 by screw connection. When the crusher is crushing materials, the guard plates 3 prevent material from splashing and reduce the risk of user injury due to material splashing.

[0025] A fixed plate 6 and a movable plate 10 are provided between the two guard plates 3. The fixed plate 6 and the movable plate 10 are respectively fixedly mounted with a fixed toothed plate 7 and a movable toothed plate 8 by means of screw connection. The top of the fixed toothed plate 7 is fixedly mounted on the fixed plate 6 by means of screw connection. The fixed plate 6 is fixedly mounted on the two guard plates 3 by means of screw connection. When the crusher is performing material crushing operation, the fixed toothed plate 7 provides rigid support and speeds up the material crushing efficiency.

[0026] The movable plate 10 is movably disposed between the two guard plates 3. Specifically, each of the two guard plates 3 is provided with a pulley 14 at its top. The two pulleys 14 are rotatably connected together by an output shaft 15. One of the pulleys 14 is connected to the motor 2, and the motor 2 provides power to drive the pulley 14 to rotate.

[0027] The top of the guard plate 3 is provided with a buckle, and a bearing is fixedly installed inside the buckle. The bearing is sleeved on the output shaft 15 and the buckle fixes the position of the output shaft 15 on the top of the guard plate 3 to prevent the pulley 14 from shifting position and causing an accident when it is operating.

[0028] like Figure 3 , Figure 4As shown, the top of the moving plate 10 is provided with a mounting cavity 24, and an eccentric cylinder 16 is provided in the mounting cavity 24. The eccentric cylinder 16 is sleeved on the output shaft 15. The rotation of the pulley 14 drives the moving plate 10 to move synchronously, and the eccentric cylinder 16 on the top of the moving plate 10 moves in a periodic elliptical trajectory, which facilitates better material crushing operations.

[0029] The bottom of the two guard plates 3 is provided with mounting bases 13. The two ends of the mounting bases 13 are fixedly mounted on the two guard plates 3 respectively. The mounting bases 13 are rotatably connected to the elbow plate 12 and the hydraulic rod 11 respectively. When the eccentric cylinder 16 rotates, the elbow plate 12 accurately transmits the power to the movable toothed plate 8, so that the movable toothed plate 8 swings back and forth according to the design requirements, ensuring the effective output of the crusher and the smooth operation of material crushing.

[0030] The bottom of the movable toothed plate 8 and the fixed toothed plate 7 together form the discharge port 22. By replacing the toggle plate 12 with different lengths, the size of the discharge port 22 of the crusher can be adjusted. When a longer toggle plate 12 is used, the stroke of the toggle plate 12 pushing the movable toothed plate 8 becomes relatively larger, and the discharge port 22 will be enlarged accordingly. Conversely, when a shorter toggle plate 12 is used, the stroke of the movable toothed plate 8 is reduced, and the discharge port 22 becomes smaller. Users can flexibly adjust the discharge port 22 according to different production needs and material characteristics to obtain crushed products of different particle sizes, thereby improving the applicability of the crusher to various production scenarios.

[0031] The hydraulic rod 11 provides assistance for the movement of the movable toothed plate 8. After the crushing operation is completed, the movable toothed plate 8 needs to be quickly reset. The hydraulic rod 11 can push the movable toothed plate 8 back to the initial position relatively smoothly and quickly through the control of hydraulic oil, ensuring the continuity and efficiency of the crusher's working cycle and improving the overall crushing efficiency.

[0032] like Figure 5 As shown, the movable toothed plate 8 and the fixed toothed plate 7 are provided with composite teeth. Preferably, the composite teeth include a first toothed part 4 and a second toothed part 5. The first toothed part 4 and the second toothed part 5 are intersectingly arranged on the movable toothed plate 8 and the fixed toothed plate 7. The pressing surfaces of the first toothed part 4 and the second toothed part 5 are intersecting arc-shaped curved surfaces with different radii. The radius of the arc-shaped curved surface of the first toothed part 4 is larger than the radius of the arc-shaped curved surface of the second toothed part 5.

[0033] The first tooth 4 is made of high-chromium cast iron and has undergone a local sintering process. Ceramic particles are embedded in the first tooth 4 to provide high-strength support, reduce wear, and resist plastic deformation during crushing operations.

[0034] The second tooth 5 is made of high manganese steel, which provides high toughness for the second tooth 5 during crushing operations and increases the service life of the second tooth 5.

[0035] In the crushing operation of the crusher, the first tooth 4 first contacts the material to carry out the crushing operation. Because the cross-sectional radius of the first tooth 4 is larger than that of the second tooth 5, the first tooth 4 provides a larger contact area on the material surface, disperses the pressure during crushing, and avoids excessive local crushing pressure on the first tooth 4, which would cause premature wear and damage. After being crushed by the first tooth 4, the second tooth 5 with a smaller radius is used to crush smaller materials. Because the radius of the second tooth 5 is smaller, it can generate greater pressure on a relatively small area, further crushing the material to meet the crushing requirements of different material particle sizes.

[0036] The alternating crushing operation of the first tooth section 4 and the second tooth section 5 reduces the wear on the movable tooth plate 8 and the fixed tooth plate 7 during the entire crushing process. Compared with the traditional single tooth design, the first tooth section 4 and the second tooth section 5 avoid excessive wear in a specific part, thus extending the service life of the entire movable tooth plate 8 and the entire fixed tooth plate 7.

[0037] like Figure 4 , Figure 6 As shown, after the crusher has been operating for a long time, the movable toothed plate 8 and the fixed toothed plate 7 need to be replaced. In this embodiment, the movable toothed plate 8 and the fixed toothed plate 7 are detachably mounted on the movable plate 10 and the fixed plate 6. Specifically, a locking block 9 is provided between the fixed plate 6 and the fixed toothed plate 7. The fixed plate 6 is provided with a groove 19, and the bottom of the fixed toothed plate 7 is provided with a groove 18. The locking block 9 is provided with a protrusion 20 and a locking hook 21. When the fixed toothed plate 7 is fixedly mounted on the fixed plate 6, the locking block 9 is inserted between the fixed toothed plate 7 and the fixed plate 6. The protrusion 20 is inserted into the groove 19, and the locking hook 21 is inserted into the groove 18. The top of the fixed toothed plate 7 is fixedly connected to the fixed plate 6 by screws, and the locking block 9 is fixedly connected to the bottom of the fixed plate 6 by screws.

[0038] When it is necessary to replace the fixed tooth plate 7, unscrew the screws at the bottom of the fixed plate 6 and the locking block 9, pull out the locking block 9, and then unscrew the screws between the fixed plate 6 and the fixed tooth plate 7. The fixed tooth plate 7 will slide down from the discharge port 22 under the action of gravity and be taken out. There is no need to take it out from the top of the fixed plate 6, which saves time.

[0039] The movable toothed plate 8 can be detached from the moving plate 10 in the same way as the fixed toothed plate 7 can be detached from the fixed plate 6. The difference is that because the movable toothed plate 8 makes periodic reciprocating motion during the crushing operation, it not only applies a squeezing effect to the material, but also has sliding friction between the material and the movable toothed plate 8, which makes the wear of the movable toothed plate 8 faster than that of the fixed toothed plate 7.

[0040] Because the movable toothed plate 8 wears out faster, it needs to be replaced more frequently than the fixed toothed plate 7. To facilitate the replacement of the movable toothed plate 8, a sliding groove is provided on the moving plate 10. Specifically, the sliding groove is composed of the locking block 9 and the moving plate 10.

[0041] The bottom of the movable toothed plate 8 is provided with a protrusion 17, which can slide back and forth in the slide groove. The slide groove reduces the friction between the locking block 9 and the movable toothed plate 8 and the moving plate 10 when replacing the movable toothed plate 8, making the replacement of the movable toothed plate 8 more convenient and quick.

The above description of the embodiments is only for the purpose of helping to understand this utility model and its core ideas.
