Description

Novel jaw plate structure

Technical Field

The utility model belongs to the technical field of jaw breaker spare part design, concretely relates to novel jaw plate structure.

Background

Jaw crushers are commonly called as jaw crushers and are also called as tiger mouths. The crushing cavity is composed of two jaw plates of a movable jaw and a static jaw, and the two jaws of an animal are simulated to move so as to finish the crushing operation of the material. The crusher is widely applied to crushing of various ores and large materials in the industries of mine smelting, building materials, highways, railways, water conservancy, chemical engineering and the like. When the jaw crusher works, the movable jaw plate makes periodic reciprocating motion to the fixed jaw plate, and the movable jaw plate is close to and away from the fixed jaw plate sometimes. When the materials approach, the materials are extruded, split and impacted between the two jaw plates to be crushed; upon exiting, the crushed material is discharged by gravity from the discharge opening.

At present, traditional jaw is the board that a upper surface has certain circular arc, the upper surface of board is equipped with a plurality of teeth that link up along length direction, be provided with a plurality of recesses that are used for losing weight at the back of board, because the jaw is when using, the material receives the lower extreme position of extruded region position in the jaw, but because the thickness of both ends position is thinner, and set up and subtract the thickness that heavy recess can reduce the work area again, consequently can shorten the life cycle of jaw, thereby the work cycle of jaw shortens and causes the cost input that the enterprise increases the jaw, the economic burden of enterprise has been increased.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problems, the utility model provides a novel jaw plate structure, which has simple, scientific and reasonable design structure and convenient use; can set up the upper surface tooth of jaw plate body into non-through structure to will subtract heavy recess setting at the intermediate position at jaw plate body back, thereby improve jaw plate body both ends work area's whole thickness, can prolong the life of jaw plate, reduce the economic burden of enterprise.

The utility model adopts the technical proposal that: the utility model provides a novel jaw plate structure, includes the jaw plate body, and the face of jaw plate body is the arc structure, and the intermediate position of arc face is equipped with a plurality of teeth, and the both ends of arc face are the platform, and the platform sets up with the top line tangent of tooth, is equipped with a plurality of recesses that subtract weight that are used for reducing jaw plate weight at the back intermediate position of jaw plate body.

The weight reduction groove is rectangular.

The weight-reducing grooves are circular in shape.

The cross section of the tooth is trapezoidal or circular arc.

When the novel jaw plate structure is used, two jaw plates are vertically placed in a jaw crusher, one jaw plate serves as a movable jaw plate, the other jaw plate serves as a static jaw plate, after the crusher is started, the movable jaw plate makes periodic reciprocating motion relative to the static jaw plate, mineral aggregate falls between the two jaw plates, and the jaw plates are crushed under the periodic extrusion action of the movable jaw plate, wherein the working areas of the two jaw plates are located at the lower end positions during crushing; the lower extreme at two jaws is because when work is impaired, can transfer the direction respectively with two jaws, and the tooth that will originally be located the upper end rotates to lower extreme work area, continues to use the jaw, and two jaws continue to carry out the breakage to the ore.

The jaw plate comprises a jaw plate body and is characterized in that the plate surface of the jaw plate body is of an arc-shaped structure, a plurality of teeth are arranged in the middle of the arc-shaped plate surface, platforms are arranged at two ends of the arc-shaped plate surface, and the platforms are arranged in a tangent mode with tooth crest lines of the teeth; the purpose of this is: tooth sets up can reduce the impaired probability of tooth in jaw board body upper surface intermediate position, and at the during operation, tooth can extrude the ore together with the platform to prolonged tooth's life, be favorable to jaw board life's extension.

A plurality of weight reduction grooves for reducing the weight of the jaw plate are formed in the middle of the back of the jaw plate body; the purpose of this is: subtract heavy recess and be used for subtracting the weight to the jaw, and will subtract heavy recess setting in jaw body back intermediate position is in order to increase the intensity at jaw both ends, avoids the jaw both ends to set up and subtracts heavy recess and make jaw life reduce.

The utility model has the advantages that: the utility model has simple structure, scientific and reasonable design and convenient use; can set up the upper surface tooth of jaw plate body into non-through structure to will subtract heavy recess setting at the intermediate position at jaw plate body back, thereby improve jaw plate body both ends work area's whole thickness, can prolong the life of jaw plate, reduce the economic burden of enterprise.

Drawings

Fig. 1 is a front perspective view of the present invention;

fig. 2 is a back perspective view of the present invention.

The labels in the figure are: 1. a jaw plate body; 2. teeth; 3. a platform; 4. and a weight reduction groove.

Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in the figure, a novel jaw plate structure, including jaw plate body 1, jaw plate body 1's face is the arc structure, and the intermediate position of arc face is equipped with a plurality of teeth 2, and the both ends of arc face are platform 3, and platform 3 sets up with the top line tangent of teeth 2, is equipped with a plurality of recesses 4 that subtract that are used for reducing jaw plate weight at the back intermediate position of jaw plate body 1.

The weight-reducing grooves 4 are rectangular in shape.

The weight-reducing grooves 4 are circular in shape.

The section of the tooth 2 is trapezoidal or circular arc.

When the novel jaw plate structure is used, two jaw plates are vertically placed in a jaw crusher, one jaw plate serves as a movable jaw plate, the other jaw plate serves as a static jaw plate, after the crusher is started, the movable jaw plate makes periodic reciprocating motion relative to the static jaw plate, mineral aggregate falls between the two jaw plates, and the jaw plates are crushed under the periodic extrusion action of the movable jaw plate, wherein the working areas of the two jaw plates are located at the lower end positions during crushing, because the two ends of the jaw plate body 1 are provided with the platforms 3, and the two ends of the back of the jaw plate body 1 are not provided with the weight reduction grooves 4, namely the thicknesses of the two ends of the jaw plate body 1 are increased compared with those of the traditional jaw plate, the capability of bearing the reaction force of ore in the extrusion process is enhanced, the working time of the two jaw plates can be prolonged, and the cost input of enterprises to the jaw plates is reduced; because work when impaired at the lower extreme of two jaws, can transfer the direction respectively with two jaws, will originally be located the tooth 2 rotations of upper end and to lower extreme work area, continue to use the jaw, two jaws continue to carry out the breakage to the ore.
