Description

Tooth Plate Device of New Type Compound Pendulum Jaw Crusher

technical field

The utility model relates to a wear-resistant plate, in particular to a novel compound pendulum jaw crusher tooth plate device.

Background technique

Compound pendulum jaw crusher is the primary crushing equipment widely used in the mining process. It has the advantages of simple structure, reliable operation and convenient maintenance. It is especially suitable for crushing hard, medium hard and brittle materials. When working, the motor of the jaw crusher drives the eccentric shaft to rotate through the pulley, and then drives the movable jaw with tooth plates to produce periodic reciprocating motion. When the movable jaw is close to the static jaw, the impact load generated by the eccentric shaft makes The material in between is crushed, split and bent, and then the material is broken and discharged through the discharge port.

In the traditional compound pendulum jaw crusher, due to the influence of factors such as the angle of the tooth profile, the depth of the tooth groove, the distance between the teeth, the arc at both ends of the tooth plate and the processing technology, the material is mainly squeezed when passing through the jaw crusher. Pressed and broken, causing the tooth plate to wear faster, the service life is short and the utilization rate is also low.

Utility model content

The utility model aims at the technical defects in the background technology, and provides a compound pendulum jaw crusher tooth plate device with long service life and high utilization rate.

The technical solution adopted by the utility model is: a new tooth plate device of compound pendulum jaw crusher, the tooth plate device is installed on the crushing movable jaw and static jaw, including a set of movable jaw lining plate and a set of static jaw lining plate and a plurality of set bolts; the movable jaw liner and the static jaw liner are respectively installed on the opposite surface of the movable jaw and the static jaw, and the upper and middle parts of the movable jaw liner and the static jaw liner are connected with the movable jaw and the static jaw with set bolts respectively. The static jaw is fixedly connected; the grinding point of the movable jaw liner and the lower part of the static jaw liner is located at the position of 1/9-1/10 of the liner length.

Both the movable jaw liner and the static jaw liner are of tooth plate structure; the tooth profile angle is 40°, the distance between the teeth is 140mm, the tooth top width is 65mm, the tooth groove depth is 75mm, and the tooth groove width is 75mm , the arc at both ends of the tooth plate is 1.6m.

The tooth plate is a shot-peened integral casting structure.

The tooth plate device disclosed in the present model has simple structure, long service life and high utilization rate of the tooth plate. After the overall processing of the casting is completed, the shot peening treatment is carried out, so that the initial hardness is increased by 20% to 30% compared with the traditional product, and the equipment is reduced. In the early stage of commissioning, the material wears on the tooth plate, and at the same time makes the product appearance more beautiful.

Figure 2 is a schematic diagram of the location of the grinding point.

In the figure: pulley 1, eccentric shaft 2, movable jaw 3, set bolt 4, movable jaw lining 5, static jaw lining 6, static jaw 7, grinding point 8.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the new model is described further.

Referring to the accompanying drawings 1-2, the tooth plate device of this new compound pendulum jaw crusher disclosed in this model is installed on the crushing mobile jaw and the static jaw, including a pulley 1, an eccentric shaft 2, a movable jaw 3, and a set bolt 4 , 5 movable jaw linings, 6 static jaw linings, 7 static jaws, and 8 grinding points.

The movable jaw liner and the static jaw liner are respectively installed on the opposite surfaces of the movable jaw and the static jaw, and the upper and middle parts of the movable jaw liner and the static jaw liner are respectively fixedly connected with the movable jaw and the static jaw with set bolts. The grinding points of the movable jaw liner and the lower part of the static jaw liner are located at 1/9-1/10 of the liner length.

Both the movable jaw liner and the static jaw liner are of tooth plate structure; the tooth profile angle is 40°, the distance between the teeth is 140mm, the tooth top width is 65mm, the tooth groove depth is 75mm, and the tooth groove width is 75mm , the arc at both ends of the tooth plate is 1.6m. The material is subjected to extrusion force and the shear force is increased, which is more suitable for the crushing of medium-hard, hard and brittle materials, and reduces the adhesive wear of materials; by increasing the transition arc at both ends of the tooth plate (the arc radius is about 1m from the traditional increase to 1.6m), so that the arc projection length accounts for about 1/3 of the total tooth plate length, and then the crushing and grinding point is moved up by 240mm. When the grinding point is worn out, the tooth plate can continue to be used by adjusting the clearance of the discharge port. There is no need to replace, prolonging the service life of the tooth plate.

The movable jaw liner and the static jaw liner are shot blasted after the casting is completed, so that the initial hardness is 20%~30% higher than that of traditional products.
