Description

Technical Field

[0001] The present invention relates to a crusher screen plate, and more particularly to a screen plate for a multi-axis shearing crusher. Background Art

[0002] In the fields of mines, chemicals, solid waste, hazardous waste, etc., the crushing treatment of large-volume materials is generally carried out by a crusher for step-by-step crushing. Common crushers include jaw crushers, roll crushers, hammer crushers, shearing crushers, etc. The main reference factors for measuring the quality of a crusher are the smoothness of material handling and the actual processing capacity of the crusher. Due to the complexity and diversity of material sources, most of the existing shear crusher screen plates are hole-type structures, with poor impact resistance. Subject to the impact of falling materials, the screen plate is prone to deformation, making it easy for materials to block the screen holes. Or due to unreasonable design, especially when facing long strip-shaped or fibrous materials, they cannot fall into the screen holes of the screen plate to the maximum extent, resulting in the materials being repeatedly involved in the crushing area by the cutter head for multiple crushing, thereby reducing the crushing efficiency, or causing the holes to be blocked, resulting in the materials being unable to fall, causing the equipment to stop. Moreover, the unreasonable selection of the screen plate material leads to the screen plate being corroded or worn out too quickly, and the screen plate needs to be replaced frequently. Frequent shutdowns cause major maintenance troubles and economic losses.

In this embodiment, the locking plates 30 are provided with a plurality of screw holes 31 for fixing by locking bolts when the locking plates 30 are installed at the installation position of the multi-axis shearing crusher.

[0023] The main screening part 11 of the sieve plate body 10 includes at least one main rib plate 12. The main rib plate 12 includes a plurality of arc-shaped first grid bars 13. The plurality of first grid bars 13 form a comb shape, and the normal line of each first grid bar 13 can point to the center line of the main cutter head. That is, the first grid bars 13 of the main rib plate 12 are distributed at intervals along the cutter shaft direction of the multi-axis shearing crusher. Profiled plates 40 are provided on both the front and rear sides of the sieve plate body 10. Two notches 41 are opened on the profiled plates 40. A support plate 60 is embedded in the notches 41 at the corresponding positions of the two profiled plates 40. After the support plate 60 is embedded, the profiled plate 40 and the support plate 60 are welded. The main screening part 11 is fixedly connected between the two support plates 60. In this embodiment, the two ends of the main screening part 11 are respectively welded to the two support plates 60. The first grid bars 13 of the main rib plate 12 are arranged at equal intervals, and the interval between two adjacent first grid bars 13 is about the thickness of two main blades. In this way, it can be ensured that the adjacent first grid bars 13 are just located in the blanking area corresponding to the adjacent main blades, which is convenient for blanking.

[0024] The multi-axis shearing crusher may include 2 or 3 main cutter heads; correspondingly, the main screening part 11 includes 2 or 3 main rib plates 12, and each main rib plate 12 corresponds to a main cutter head. During use, the main rib plate 12 is located directly below the corresponding main cutter head, and the normal line of the first grid bar 13 on each main rib plate 12 points to the center line of the corresponding main cutter head. When the main screening part 11 includes 2 or 3 main rib plates 12, the number of the first grid bars 13 of the 2 or 3 main rib plates 12 is equal and the positions are corresponding, and the first grid bars 13 at the corresponding positions are integrally formed. Designed in this way, the main screening part 11 has no axial rib plates as a whole, and the material is not easily blocked by the first grid bars 13. In this embodiment, the main screening part 11 includes 2 main rib plates 12.

[0025] An arc-shaped plate 70 is provided on both the left and right sides of the main screening part 11. One end of the arc-shaped plate 70 is fixedly connected to the support plate 60, and the other end is fixedly connected to the support side plate 20; wherein, the normal line of the arc-shaped plate 70 can point to the center line of the auxiliary cutter head. Preferably, the arc-shaped plate 70 is a whole plate without openings. A secondary rib plate 71 is provided below each arc-shaped plate 70. The secondary rib plate 71 includes a plurality of arc-shaped second grid bars 72. The plurality of second grid bars 72 form a comb shape, and the normal line of each second grid bar 72 can point to the center line of the auxiliary cutter head. One end of the second grid bar 72 of the secondary rib plate 71 is welded to the support plate 60, and the other end is welded to the support side plate 20. It can be used as a reinforcing rib to increase the impact resistance of the sieve plate 50. The second grid bars 72 on the secondary rib plate 71 are arranged at equal intervals, and the interval between two adjacent second grid bars 72 is about the thickness of two auxiliary blades.

[0026] In use, above the main sieve part 11 of the sieve plate 50 for a multi-axis shearing crusher, there is a main cutter head, and above the area corresponding to the arc-shaped plate 70, there is an auxiliary cutter head. The multi-axis shearing crusher mainly crushes materials by shearing and tearing them with the main cutter head. The main function of the auxiliary cutter head is to rewind the strip-shaped or large-piece materials coming out after being crushed by the main cutter head and then crush them again. The main rib plate 12 includes a plurality of arc-shaped first gratings, which can allow the materials with a particle size smaller than the interval of the first gratings to easily fall after being crushed by the main cutter head. The materials with a particle size larger than the interval of the gratings are either hooked by the cutter teeth of the main cutter head to the arc-shaped plate 70 and then wound out by the cutter teeth of the auxiliary cutter head and sent above the main cutter head for secondary shearing; or directly rewound onto the main cutter head for re-crushing.

[0027] If the main sieve part 11 is provided with axial rib plates, it will cause strip-shaped materials, especially fibrous materials, to be caught, thus blocking the main sieve part. However, the main sieve part 11 of the present invention is not provided with axial rib plates. Therefore, for the large-piece materials or fibrous materials that are not completely crushed, they are either hooked by the cutter teeth of the main cutter head to the arc-shaped plate and then wound out by the cutter teeth of the auxiliary cutter head and sent above the main cutter head for secondary shearing; or directly rewound onto the main cutter head for re-crushing.

[0028] The arc-shaped plate 70 is a whole plate without holes. If the arc-shaped plate 70 has holes / slots, it will cause large-piece materials to accumulate at the holes, resulting in a reduction in the effective passing hole area, and the probability of large-particle-size materials accumulating again will increase sharply. However, the arc-shaped plate 70 of the present invention does not undertake the task of discharging materials. The materials are only wound out by the auxiliary cutter head and sent to the main cutter head for secondary crushing. In this way, the multi-axis shearing crusher has a better crushing effect and higher crushing efficiency.

[0029] In summary, the sieve plate for a multi-axis shearing crusher provided by the present invention has a simple structure, is easy to process and maintain, has strong impact resistance, is not sensitive to the abrasion of materials, has a better crushing effect, higher crushing efficiency, better anti-blocking performance for long strip-shaped fiber materials or flexible and slender materials such as ton bags, rags, and cloth strips, and is more suitable for crushing complex materials.

[0030] The above is the preferred embodiment of the present invention and the technical principles applied. For those skilled in the art, any obvious changes such as equivalent transformations and simple replacements based on the technical solution of the present invention without departing from the spirit and scope of the present invention shall fall within the protection scope of the present invention.
