Technical Field
The utility model relates to a cleaner production technical field, especially a jaw plate of jaw crusher.
Background
Jaw crushers are mainly used as coarse crushers and medium crushers in the departments of mines, building materials, capital constructions and the like. The device is divided into a large machine, a medium machine and a small machine according to the width of the feed inlet, wherein the large machine is used for feeding materials with the width of more than 600MM, the medium machine is used for feeding materials with the width of 300-600MM, and the small machine is used for feeding materials with the width of less than 300 MM. The jaw crusher has simple structure, easy manufacture and reliable work.
The working part of the jaw crusher is two jaw plates, one is a fixed jaw plate (fixed jaw), the fixed jaw plate is vertically (or the upper end of the fixed jaw plate is slightly outwards inclined) fixed on the front wall of the crusher body, and the other is a movable jaw plate (movable jaw), the position of the movable jaw plate is inclined, and the movable jaw plate and the fixed jaw plate form a crushing cavity (working cavity) with a large upper part and a small lower part. The movable jaw is periodically reciprocated, away from and towards the fixed jaw. When the materials are separated, the materials enter the crushing cavity, and finished products are discharged from the lower part; when approaching, the material between the two jaws is squeezed, bent and split to be broken.
Jaw crushers may be classified into a simple swing type jaw crusher (simple swing jaw crusher), a complex swing type jaw crusher (complex swing jaw crusher), and a comprehensive swing type jaw crusher according to different swing modes of movable jaws. In the case of jaw crushers, although the types of construction differ, their operating principle is basically similar, except that the movement trajectory of the movable jaw differs. In summary, when the movable jaw plate makes periodic reciprocating motion to the fixed jaw plate around the suspension shaft, the movable jaw plate is moved close to and away from the fixed jaw plate, and when the movable jaw plate is moved close to the fixed jaw plate, ore between the two jaw plates is crushed by the combined action of crushing, splitting and bending and breaking; when the movable jaw plate leaves the fixed jaw plate, the crushed ore is discharged from an ore discharge port of the crusher under the action of gravity, but once the jaw plate of the existing jaw crusher is damaged, the whole jaw plate needs to be disassembled and integrally replaced, the maintenance is difficult, and the replacement of the whole jaw plate increases the production cost.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a jaw crusher's jaw to the problem that the whole change that carries on is damaged to the jaw of solving current jaw crusher.

Preferably, the rack comprises a first straight line section, arc sections are integrally formed at two ends of the first straight line section, the arc sections are symmetrical along the cross section where the midpoint of the first straight line section is located, a second straight line section is integrally formed at the other end of the arc sections, and the second straight line section is parallel to the first straight line section.
Preferably, the side wall of the fastener is provided with an anti-slip ring along the circumferential direction of the side wall, the blind hole is internally provided with an anti-slip groove, and the anti-slip ring is clamped in the anti-slip groove.
Preferably, the anti-slip ring and the anti-slip groove are uniformly distributed.
Preferably, at least two blind holes are formed in the rack, and the blind holes are uniformly distributed along the length direction of the rack.
Preferably, the non-working surface of the base plate is provided with a plurality of weight-reducing grooves, and one threaded through hole is positioned in one weight-reducing groove.
Compared with the prior art, the beneficial effects of the utility model are that: along with the increase of bolt twist screw thread through-hole length, the bolt expands the awl section of thick bamboo that the arc is constituteed, and the outer wall of the awl section of thick bamboo of expanding is hugged closely with the inner wall of blind hole to with the rack joint on the base plate, can change the rack of damage alone, practiced thrift manufacturing cost.
