Abstract
The utility model discloses a movable jaw pull rod for connecting a movable jaw of a jaw crusher. The movable jaw pull rod comprises a pull rod fixing plate and a movable jaw, wherein an adjusting pull rod is connected to the pull rod fixing plate, the end located in the pull rod fixing plate of the adjusting pull rod is connected with the movable jaw, a spring, a spring cover plate and a spring lug seat are sleeved at the outside of the pull rod fixing plate on the adjusting pull rod, the spring cover plate and the spring lug seat are respectively located on the two ends of the spring, a nut is connected to the end part of the adjusting pull rod, and the nut is in contact with the spring cover plate; and a bearing seat is connected to the pull rod fixing plate, a bearing is arranged in the bearing seat, and two lug shafts of the spring lug seat are mutually matched with the bearing. According to the utility model, a spring seat and a spherical surface seat used for fixing the movable jaw of the jaw crusher are replaced by the spring lug seat, and the two lug shafts of the spring lug seat are matched with the bearing, so that the mechanism is convenient to lubricate and less in attrition on one hand, and on the other hand, compared with the existing spherical surface slide, the mechanism performance of hinge connection is more reliable, so that the maintenance frequency can be reduced.
Description
Technical field
The utility model relates to a kind of moving jaw pull bar that connects the moving jaw of jaw crusher, belongs to the jaw crusher technical field.
Background technology
It is broken that jaw crusher is commonly called as jaw, by moving jaw with decide two jaws of jaw and form crusher chamber, two jaw movements of simulated animal and complete the disintegrating machine of material crushing operation.Be widely used in the industries such as mine, smelting, building materials, highway, railway, water conservancy and chemical industry.Jaw crusher is completed moving jaw plate by the driven by motor bent axle and is moved back and forth, and utilizes extruding between moving jaw plate and quiet jaw to complete the fragmentation of material.In shattering process, the epimere of moving jaw is connected with bent axle, the lower end is provided with the adjusting device of regulating opening, the bracket of adjusting device is being regulated between oil cylinder and moving jaw, because of bracket and moving jaw be connected being connected without fixture of oil cylinder, come off from two contact points for preventing bracket, be provided with pull-rod spring mechanism in the bottom of moving jaw, in moving jaw movement process, pull-rod spring mechanism also need complete flexible and wobbling action.Existing jaw crusher pull-rod spring mechanism coordinates to complete with spheric seating with spring base for realizing swinging, this mechanism is because close contact between spring base and spheric seating can't lubricate again, cause easily abrasion damage between contact-making surface, affect the result of use of jaw crusher.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of lubricated convenience is provided, weares and teares little, the moving jaw pull bar of the moving jaw of the connection jaw crusher of dependable performance can overcome the deficiencies in the prior art.
The technical solution of the utility model is: jaw crusher pull-rod spring mechanism, its bag pull bar fixed head and moving jaw, connect adjusting yoke on the pull bar fixed head, the end that adjusting yoke is positioned at the pull bar fixed head is connected with moving jaw, outer cover at adjusting yoke upper connecting rod fixed head is connected to spring, spring bumper cover and spring ear seat, spring bumper cover and spring ear seat lay respectively at the two ends of spring, are connected with nut in the end of adjusting yoke, and nut contacts with spring bumper cover; Be connected with bearing block on the pull bar fixed head, be provided with bearing in bearing block, two gudgeons and the bearing of spring ear seat cooperatively interact.
Bearing block is provided with lubricating cup.
Be connected with dust shield cover on bearing block.
Described bearing is self-aligning roller bearing.
Compared with the prior art, the utility model will have spring base of pull-rod spring mechanism of jaw crusher and spheric seating now with spring ear seat and bearing substitute, two gudgeons and the bearing fit of spring ear seat, because of the pull-rod spring mechanism kinematic frequent, such first can make this mechanism lubricated convenient, weares and teares little; The second, relatively existing sphere slides, and the mechanism performance that free bearing connects is more reliable, can reduce frequency of maintenance.Lubricating cup is set on bearing block, convenient like this to bearing oiling, raising bearing life; Be connected with dust shield cover on bearing block, can further protect bearing like this.The bearing self-aligning roller bearing so both can guarantee the rotation of the moving clockwise sub-rotation direction of jaw, can realize again the slight swing of non-rotor shaft direction under a stable condition, made it more can satisfy the job requirement of jaw crusher.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is complete machine structure schematic diagram of the present utility model.
The specific embodiment
embodiment 1: as shown in Figure 1, the lower end of moving jaw 2 is connected on pull bar fixed head 1 by pull-rod spring mechanism, the main body of pull-rod spring mechanism is adjusting yoke 3, and adjusting yoke 3 is connected on pull bar fixed head 1 by the mode of inserting, and adjusting screw(rod) 3 one end positions and moving jaw 2 are hinged, the outside at adjusting yoke 3 upper connecting rod fixed heads 1 is socketed with spring 4, spring bumper cover 5 and spring ear seat 6, spring bumper cover 5 and spring ear seat 6 lay respectively at the two ends of spring 4, be connected with nut 7 in the end of adjusting yoke 3, nut 7 contacts with spring bumper cover 5, both sides at pull bar fixed head 1 adjusted pull bar 3 insertion portions are connected with bearing block 8, be provided with bearing 9 in bearing block 8, two gudgeons and the bearing 9 of spring ear seat 6 cooperatively interact, the impact of tension member spring mechanism, pull-rod spring mechanism can follow moving jaw movement in the process of moving jaw movement like this, realize the flexible of joint pull bar 3 and swing, for guaranteeing the service life of bearing, be provided with lubricating cup 10 and be connected with dust shield cover 11 on bearing block 8, described bearing 9 is self-aligning roller bearing.
