[0021] Example 1

[0022] like Figure 1 As shown, a movable toothed plate includes a toothed plate body 1. Several irregularly shaped toothed racks 2 are provided on one side of the toothed plate body 1. Jaw crushing zones 21 on the irregularly shaped toothed racks 2 are coaxially distributed or alternately staggered along the width direction of the toothed plate body 1. A jaw crushing zone 21 is provided in the middle of the irregularly shaped toothed racks 2. The tooth profile height of the jaw crushing zone 21 is lower than that of the irregularly shaped toothed racks 2 on both sides. The jaw crushing zone 21 is a continuous groove extending along the length direction of the irregularly shaped toothed racks 2. By setting the jaw crushing zone 21 in the middle of the irregularly shaped toothed racks 2, the movable toothed plate effectively reduces the tooth profile height of this area, so that the material can be subjected to more concentrated extrusion and shearing forces when passing through the jaw crushing zone 21, thus promoting the crushing and dispersion of the material. The jaw crushing zone 21, as a continuous groove extending along the length of the irregular toothed rack 2, enhances the crushing function of the rack and also plays an auxiliary role in material discharge, avoiding the material jamming phenomenon that is easy to occur in ordinary moving toothed plates, and improving the continuity and efficiency of operation. In addition, the jaw crushing zone 21 can be coaxially distributed or alternately staggered along the width of the toothed plate body 1. This layout can be flexibly adjusted according to specific working conditions. Different distribution forms have a significant impact on the crushing and discharge effect of materials.

[0023] Furthermore, the cross-section of the jaw crushing zone 21 can be designed as arc-shaped, V-shaped, or trapezoidal to adapt to different crushing requirements and material properties. In this embodiment, such as Figures 3-4As shown, the jaw crushing zone 21 adopts a trapezoidal cross-section structure, with its bottom and walls forming a certain angle. This trapezoidal structure not only increases the stress-bearing area of ​​the jaw crushing zone 21, but also effectively guides the material to slide along the bottom of the tank, achieving more uniform stress and more efficient crushing effect.

[0024] Furthermore, an impact section 23 is provided on the trough wall, which is used to enhance the impact and shearing action of the material during the flow process. The impact section 23 can generate additional impact force when the material enters the jaw crushing zone 21, promote the crushing and refinement of the material, reduce the residue of large pieces of material, and improve the crushing quality; furthermore, the impact section 23 is one or more combinations of pyramidal protrusions, hemispherical protrusions, and strip ribs protruding from the trough wall.

[0025] like Figure 1 and Figure 3 As shown, a guide groove 22 is also provided on the toothed plate body 1. At least part of the guide groove 22 is connected to the jaw crushing area 21. The guide groove 22 is located between the two toothed plates. Guided by the guide groove 22, the crushed powder can be discharged from the working area quickly and orderly, avoiding the accumulation and blockage of materials.

[0026] Furthermore, at least two straight toothed racks 3 are provided on the toothed plate body 1. The tooth profile height of the straight toothed racks 3 is greater than or equal to the tooth profile height of the irregular toothed racks 2. The straight toothed racks 3 are located on both sides of the toothed plate body 1 in the width direction, while the irregular toothed racks 2 are concentrated in the middle area of ​​the toothed plate body 1 in the width direction. In addition, the distribution of the straight toothed racks 3 and the irregular toothed racks 2 can also be changed according to the actual working conditions. For example, the straight toothed racks 3 and the irregular toothed racks 2 can be alternately distributed along the width direction of the toothed plate body 1. Due to their higher tooth profile height, the straight toothed racks 3 are mainly responsible for the initial crushing and strong shearing of large pieces of material, while the jaw crushing zone 21 in the middle area is subjected to force escape. At the same time, the irregular toothed racks 2 perform more detailed and uniform crushing of the material through the jaw crushing zone 21 and the special tooth profile shape, ensuring the fineness and thorough crushing of the material.

[0027] To further ensure the structural strength of the moving tooth plate, such as Figure 2 and Figure 5 As shown, a number of reinforcing ribs 4 are provided on the side of the toothed plate body 1 away from the irregular toothed rack 2. The reinforcing ribs 4 are distributed in a cross pattern, which greatly improves the rigidity of the toothed plate body 1 and prevents it from deforming or breaking under huge impact forces.

[0028] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
