Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a cutting component of a crusher. Background Art

[0002] Crusher is generally used to process large bulk materials. Through the cutting action of the blade, the large bulk materials are crushed into smaller fragments for subsequent separation and recovery.

[0003] Existing crusher blades generally consist of a cutter disc and multiple cutting blades. The cutting blades are subject to significant wear and tear from long periods of cutting hard materials, making them prone to bending and damage. However, discarding the entire cutter disc due to damage to individual cutting blades results in significant material waste. Furthermore, after the crusher blades have finished crushing the material, smaller pieces can easily find their way between adjacent crusher blades, preventing further crushing and affecting the crushing quality. Therefore, a cutting assembly for a crusher is proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the problems raised in the background technology and to propose a cutting assembly for a crusher.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A cutting assembly of a crusher includes a cutter disc and a plurality of cutting knives arranged on the circumferential wall of the cutter disc, wherein the plurality of cutting knives are fixedly connected to the cutter disc by the cooperation of bolts and nuts; an annular mounting groove is provided on the side wall of the cutter disc, and a plurality of evenly distributed side cutting strips are fixedly provided inside the annular mounting groove.

[0007] Preferably, the tip of the cutting knife is provided with a coarse cutting edge and a fine cutting edge.

[0008] Preferably, a mounting block is fixedly provided at the bottom of the cutting knife, a mounting slot is provided on the circumferential wall of the cutter disc, the mounting block is plugged into the mounting slot, and the rod wall of the bolt is arranged to pass through the interior of the mounting block.

[0009] Preferably, one side of the side cutting strip is a vertical surface, and the other side of the side cutting strip is an inclined surface, and a side cutting blade is provided on the top of the side cutting strip.

[0010] Preferably, the side cutting strips are provided on both side surfaces of the cutter disc, and the side cutting strips protrude and extend to the outside of the annular mounting groove.

[0011] Preferably, a mounting hole is provided in the middle of the cutter disc, and a limiting slot is provided on one side of the mounting hole.

[0012] Compared with the prior art, the present utility model provides a cutting assembly of a crusher, which has the following beneficial effects:

[0013] 1. For the cutting assembly of this crusher, through the bolts and nuts arranged between the blade and the cutting knife, when individual cutting knives are severely worn, the bolts and nuts can be loosened with a wrench and separated, so that the cutting knife can be disassembled and separated from the cutter head, and a new cutting knife can be replaced without replacing the entire cutter head, avoiding the phenomenon of material loss.

[0014] 2. For the cutting assembly of this crusher, through the side cutting strips arranged on the cutter head, during the cutting process, if materials enter between adjacent cutter heads, the side cutting strips can break the materials at this time, thereby improving the crushing quality of the materials.

[0015] For the parts not involved in this device, they are the same as or can be implemented by the prior art. The present utility model can separately disassemble and replace a single damaged cutting knife without replacing the entire cutter head, avoiding the phenomenon of material loss. At the same time, side cutting strips are arranged on both sides of the cutter head, which can improve the crushing quality of the materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0022] Referring to Figure 1 and 3 , a cutting assembly of a crusher, comprising a cutter head 1 and a plurality of cutting blades 2 arranged on the circumferential wall of the cutter head 1. The tip of the cutting blade 2 is provided with a rough cutting edge and a fine cutting edge, which can first coarsely crush the material and then finely crush it. The plurality of cutting blades 2 are fixedly connected to the cutter head 1 through the cooperation of bolts 3 and nuts 4. The bottom of the cutting blade 2 is fixedly provided with a mounting insert block 7, and a mounting slot 8 is formed on the circumferential wall of the cutter head 1. The mounting insert block 7 is inserted and matched with the mounting slot 8. The rod wall of the bolt 3 passes through the inside of the mounting insert block 7. When it is necessary to disassemble the damaged cutting blade 2, loosen the bolt 3 and the nut 4 with a wrench, and then pull out the bolt 3 from the inside of the mounting insert block 7, so that the mounting insert block 7 can be taken out from the inside of the mounting slot 8, thereby the cutting blade 2 can be disassembled and replaced.
