Description

Technical Field

[0001] This utility model belongs to the field of ore crushing and processing machinery, and mainly relates to a working component installed on a jaw crusher. Background Technology

[0002] Jaw crushers are commonly used rock-crushing machines in current mining operations. During ore crushing, the relative compression motion of two jaw plates with vertical strip-shaped teeth, configured as a relatively integral V-shape, crushes the ore fed from above into the space between the two jaw plates. The crushed ore is then discharged from below the jaw plates by gravity, completing the crushing process. However, years of practical experience in ore crushing have revealed that because the jaw plates are currently used as integral cast components—meaning the strip-shaped teeth and jaw bed are a rigid, one-piece structure—when the strip-shaped teeth experience partial or complete wear and damage, rendering them unusable, the entire jaw plate must be replaced. This not only results in the waste of a large amount of expensive alloy materials but also significantly increases the operating costs of ore crushing operations, impacting and reducing the economic efficiency of mining operations. Summary of the Invention

[0003] The purpose of this invention is to address the problems existing in the prior art and, in combination with the actual needs of current ore crushing and processing operations, to develop and design a new structure of jaw crusher jaw plate, so as to reduce the loss and waste of expensive alloy metal materials and reduce the cost of ore crushing and processing operations.

[0004] The basic design of this utility model is as follows: multiple through holes are evenly distributed along the vertical and horizontal directions on the jawbone. Parallel strip-shaped protrusions are arranged on one side of the jawbone, along the vertical direction and located on the left and right sides of the through holes. An annular groove is formed on the outer circumferential surface of the tooth. A spring sleeve is axially positioned and fitted onto the annular groove of the cylinder. The spring sleeve is inserted into the through hole on the jawbone. The friction generated by the outward expansion and compression between the outer surface of the spring sleeve and the inner surface of the through hole axially positions the tooth within the through hole. The tooth located on the outer side of the through hole is engaged between adjacent strip-shaped protrusions. The tooth is circumferentially locked within the through hole by the locking fit between the vertical sidewall of the strip-shaped protrusion and the outer surface of the tooth. Thus, the tooth is fixedly assembled and installed on the jawbone, forming the jaw plate of a jaw crusher.

[0005] This utility model adopts a separate assembly structure for the jawbone and teeth, which fundamentally overcomes and solves the shortcomings and problems of the existing integral jawbone. It has the characteristics of simple, novel and reasonable structure, easy, convenient and quick operation for changing teeth on the jawbone, saving metal materials, low processing cost, good crushing quality and high operation efficiency.

[0021] 1. Gland 1-1, Through hole 1-2, Strip-shaped boss 2. Tooth 2-1, Column 2-2, Annular groove 3. Spring sleeve Detailed Implementation

[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] A jaw crusher jaw plate has multiple through holes 1-1 evenly distributed along the vertical and horizontal directions on the jaw bed 1. On one side of the jaw bed 1, parallel strip-shaped bosses 1-2 are arranged along the vertical direction, located to the left and right of the through holes 1-1. An annular groove 2-2 is formed on the outer circumferential surface of the column 2-1 of the tooth 2. A spring sleeve 3 is axially positioned and fitted onto the annular groove 2-2 of the column 2-1. The spring sleeve 3 is inserted into the through hole 1-1 fitted on the jaw bed 1. The friction generated by the outward expansion and compression between the outer surface of the spring sleeve 3 and the inner surface of the through hole 1-1 axially positions the tooth 2 within the through hole 1-1. The outer part of the tooth 2 is engaged between adjacent strip-shaped bosses 1-2. The engagement between the vertical sidewall of the strip-shaped bosses 1-2 and the outer surface of the tooth 2 locks the tooth 2 circumferentially within the through hole 1-1, thus fixing the tooth 2 onto the jaw bed 1. The tooth 2 includes a single-column frustum-shaped tooth, a single-column trapezoidal tooth, and a single-column polygonal tooth, and the tooth 2 also includes a double-column trapezoidal tooth.

[0024] During ore crushing operations, when partial or complete wear or damage to the teeth 2 on the jaw 1 affects the quality and efficiency of the crushing process, the worn or damaged teeth 2 can be removed and replaced. The specific procedure is as follows: Using a striking method, push the teeth 2 and spring sleeve 3 out of the through hole 1-1 on the jaw 1 from the bottom. Then, insert the new teeth 2 and spring sleeve 3 into the through hole 1-1 on the jaw 1 to complete the replacement. The jaw 1 itself does not need to be replaced. If the old spring sleeve 3 is still usable, it can be fitted onto the new teeth 2 for continued use without replacement.
