Description
Technical field
It the utility model is related to jaw crusher technical field, more particularly to a kind of jaw crusher multitooth plate.
Background technology
Jaw crusher has that reduction ratio is big, product granularity is uniform, simple in construction, reliable operation, maintenance are easy, operating charges
With it is low the features such as, be widely used in the departments such as mine, metallurgy, building materials, highway, railway.In jaw crusher, tooth plate is direct
The part contacted with ore, tooth plate is constantly extruded by material, ground, impacted during broken material, the gradual quilt of the flank of tooth
Abrasion, causes discharging-material size constantly to increase, and has severely impacted broken quality.In production, the tooth plate of jaw crusher disappears
Consumption, have a direct impact to the height of whole broken cost.
Utility model content
The defects of the purpose of this utility model is to overcome in the prior art, there is provided a kind of jaw crusher multitooth plate, it is real
Show extension tooth plate service life, improve fragmentation quality, while saved production cost.
The technical solution adopted in the utility model is：
A kind of jaw crusher multitooth plate, including plate body, the plate body cuboid-type and at its length direction both ends
Mounting head is provided with below end face, parallel interval is provided with some stepped tooths along its length in plate body upper surface, and its feature exists
In：The top of the stepped tooth and the tooth side of root use arc transition, the stepped tooth center of top along length
Direction is provided with lance tooth.
Further, plate body, mounting head, stepped tooth and the lance tooth are an entirety, integration processing and
Into,.
Further, two grooves, and groove or so are offered along its width in the lower surface of the plate body
It is symmetricly set on the lower surface of plate body, makes the weight saving of tooth plate, saves high-abrasive material, the stabilization of increase tooth plate and dynamic jaw
Property.
Further, the space width l of the two neighboring stepped tooth is 1~5 times of two neighboring stepped tooth tooth root away from n,
The top of the stepped tooth and the tooth side of root use arc transition, and radius of curvature r is two neighboring stepped tooth tooth root away from n's
0.1~0.3 times, the high h of tooth of the stepped tooth is 2~6 times of two neighboring stepped tooth tooth root away from n, the tooth of the lance tooth
High m is 0.3~0.5 times of two neighboring stepped tooth tooth root away from n, the parameters of structural dimension of stepped tooth and lance tooth is carried out excellent
Change, improve tooth plate intensity and using effect.
The beneficial effects of the utility model are：
This utility model for overcome existing tooth plate in use existing serious wear the problem of, to toothed plate structure
Toothed plate structure is carried out redesign and parameters of structural dimension is optimized, circular arc mistake is used on stepped tooth tooth side
Cross, and increase lance tooth in tooth top, it is excellent on the advantages of lance tooth crushing effect is good and round-arced tooth surface intensity is high is integrated
Change trapezoidal toothed, using effect can be improved, material carries out linear contact lay attrition crushing with tooth plate, and crushing effect is good.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is overlooking the structure diagram of the present utility model.
Fig. 3 is partial enlargement structural representation at A in Fig. 1.
Embodiment
In order that the advantages of the purpose of this utility model and technical scheme, is more clearly understood, below in conjunction with accompanying drawing and reality
Example, the utility model is further elaborated.
As shown in accompanying drawing 1~3, a kind of jaw crusher multitooth plate, including plate body 1, the cuboid-type of plate body 1 and
Mounting head 2 is provided with below its length direction both ends end face, if parallel interval is provided with along its length in the upper surface of plate body 1
Dry stepped tooth 3, the top of the stepped tooth 3 and the tooth side of root use arc transition, in the center of top of the stepped tooth 3
Alongst it is provided with lance tooth 4.
The plate body 1, mounting head 2, stepped tooth 3 and lance tooth 4 are an entirety, and integration is process.
In the lower surface of the plate body 1 two groove 1-1, and groove 1-1 or so pairs are offered along its width
Title is arranged on the lower surface of plate body 1.
Two neighboring stepped tooth tooth root away from n=3mm,
The space width l=10mm of the two neighboring stepped tooth
Stepped tooth excessive circular radius of curvature r=0.4mm
The high h=6.5mm of tooth of stepped tooth
The high m=1mm of tooth of lance tooth.
The operating mechanism of jaw crusher is a typical quadric chain, and dynamic jaw is done back and forth under the drive of eccentric shaft
Motion, when moving jaw close to fixed-tooth plate, extruding, impact, fragmentation are produced with the material of contact, raw meal particle size reduces.When dynamic jaw
During away from fixed-tooth plate, material is fallen due to the motion of self gravitation and moving tooth plate complexity, and extruding is produced between tooth plate and material
With the phenomenon of grinding, tooth plate attrition crushing power is given in the motion of tooth plate in the horizontal direction, and the effect in tooth plate vertical direction makes thing
Material is also ground while falling to material.Under the extruding of material, impact, broken comprehensive function, tooth plate material is from table
Emaciated face falls, and forms a number of peel off and cheats or extrude hole.Tooth plate in the utility model is in comprehensive lance tooth crushing effect
Optimize trapezoidal toothed on the advantages of good and round-arced tooth surface intensity is high, using effect can be improved, material enters line with tooth plate and connect
Attrition crushing is touched, crushing effect is good.
