Description
Technical field
The utility model belongs to mining machinery and manufactures and designs the field, especially belongs to jaw crusher and manufactures and designs the field, particularly the protector of jaw crusher bracket and bracket box.
Background technology
At present, jaw crusher extensively adopts bracket, and plays crucial effects in the bracket jaw crusher, mainly contains: 1, transferring power; 2, cross the iron protective effect; 3, change the bracket of different length, can adjust the discharge gate size.Jaw crusher is typically to be the general heavy-duty machine on basis with the quadric chain, and wherein bracket is played the part of the role of rocking bar in the broken machine of jaw, so guarantee that the bracket operate as normal is an important assurance of machine steady operation.
During the jaw crusher running, bracket rolls at bracket box inner face back and forth, and the bracket face keeps vertical basically with the bracket box.When feed; Not having material unavoidably falls in the bracket box; The building stones dust gets into the contact-making surface of bracket and bracket box; At this moment the bracket arc surface contacts with bracket box inner face and becomes mediate contact, and bracket becomes slip by rolling, or makes bracket slide into bracket box angular position to roll and possibly roll and slide and deposit.Slide influence bracket and bracket box life-span, because of back bracket face and the bracket box inner face out of plumb of sliding, cause bracket not rise to be the iron protection, maybe because of load high back bracket just appearance be out of shape or rupture; Because of slide back bracket and moving carniculus degree change, influence the serviceability of entire machine.
In jaw crusher, also do not have at present a kind ofly to protect bracket and bracket case connecting structure, can increase the service life, protector and method easy for installation.
Summary of the invention
The utility model discloses the protector of a kind of jaw crusher bracket and bracket box according to the deficiency of prior art; The problem that the utility model will solve provides a kind of convenient installation; Need not change jaw crusher bracket and bracket box and crusher structure, can realize the protector of bracket and bracket case connecting structure protection.
The utility model provides following technical scheme to realize:
The protector of jaw crusher bracket and bracket box; Comprise moving jaw, bracket and bracket box; The bracket box is positioned at moving jaw back part and flexibly connects with bracket, wherein: on " V " shape groove that moving jaw, bracket become with the bracket box-like, be equipped with and cover all elasticity skin blocks of " V " shape groove.
Said elasticity skin block one end is fixed on the moving jaw with bolt, press strip, and the elasticity skin block after the other end bending is connected with the bracket surface activity.
Said elasticity skin block utilizes the frictional force on elasticity skin block elasticity and bracket surface and bracket to remain applying and do not have the gap.
The width of said elasticity skin block is greater than the width of bracket.
When above-mentioned protector was installed, the auger shell pit in moving jaw relevant position, elasticity skin block be punching above that also, was fixed on the moving jaw with press strip; The elasticity skin block other end bends, and utilizes the frictional force of elasticity skin block and bracket face, and the elasticity skin block is fixed on the bracket face.
Usually adopt the rubber of suitable thickness to make the elasticity skin block,, it is constantly extended and bending in machine operation procedure, and also have very strong fatigability because of the rubber stop leatherware has fabulous plasticity and toughness.
The width of elasticity skin block is wideer than bracket, and materials such as assurance building stones, water are discharged from two ends on skin block.Elasticity skin block and bracket remain applying, and do not have the gap.
In sum; The utility model is through adding the elasticity skin block on moving jaw; And utilize skin block elasticity and bracket to remain flexible connection, the utlity model has following helpfulness: prevented that materials such as building stones, water from falling in the bracket box, guaranteed the clean serviceability that guarantees machine in the bracket box.And this is simple in structure, and is easy for installation, and cost is low.

The specific embodiment
Through the specific embodiment and accompanying drawing the utility model is further specified below.Embodiment is used to explain the utility model, limits the utility model never in any form.
In conjunction with Fig. 1 to Fig. 3; As shown in the figure: the protector of jaw crusher bracket and bracket box; Comprise moving jaw 5, bracket 4 and bracket box 8; Bracket box 8 is positioned at moving jaw 5 back parts and flexibly connects with bracket 4, on " V " shape groove 7 that moving jaw 5, bracket 4 and bracket box 8 form, is equipped with and covers all elasticity skin blocks 1 of " V " shape groove 7.Elasticity skin block 1 one ends are fixed on the moving jaw 5 with bolt 3, press strip 2, and the elasticity skin block 1 after the other end bending is connected with bracket 4 surface activities.
This routine elasticity skin block adopts the rubber skin block.
When protector is installed, bore the screwed hole of 4 16mm in moving jaw 5 relevant positions, rubber skin block 1 wide length is thick to be respectively 150 * 650 * 10mm, also makes a call to the hole of 4 16mm above that, and thick with wide length is respectively that 40 * 600 * 8mm press strip 2 is fixed on the moving jaw 5.The width of rubber skin block 1 is wideer than bracket 4, and materials such as assurance building stones, water are discharged from two ends on rubber skin block 1.Rubber skin block 1 remains applying with bracket 4, and does not have the gap.
In conjunction with Fig. 1, Fig. 2, Fig. 3, among Fig. 1 press strip 2 is pressed on the rubber skin block 1, the hole alignment is installed rubber skin block 1 bolt group rubber skin block 1 is fixed on the moving jaw 5.Bending rubber skin block 1 utilizes the frictional force of 4 of rubber skin block 1 and brackets, and rubber skin block 1 is fixed on 4 of the brackets.Disintegrating machine is in operation process, and rubber skin block 1 is close to bracket 4 all the time and is closed, and falls into materials such as building stones on the rubber skin block 1, water along with direction 6 flows out.
In conjunction with Fig. 4 and Fig. 5, Fig. 4 is unshielded device jaw crusher sketch map; Fig. 5 is unshielded device jaw crusher bracket and bracket box structural representation.The disintegrating machine that protector is not installed is in work; Not having material unavoidably falls on the bracket 4; Through the vibrations of machine itself, material slowly will be fallen in the bracket box 8, and bracket 4 arc surfaces contact with bracket box 8 inner faces and become mediate contact; Bracket 4 becomes slip by rolling, or makes bracket 4 slide into bracket box 8 angular positions to roll and possibly roll and slide and deposit.Make the wearing and tearing aggravation of bracket 4,, also might cause bracket 4 to break away from bracket boxes 8 when material gets into when too much.
