Abstract
The utility model discloses a kind of dynamic jaw spring drag link mechanism of band lubrication of jaw crusher, it comprises pull bar fixed head (1) and dynamic jaw (2), the through hole of pull bar fixed head (1) is inserted with adjusting yoke (3), sphere seat board (4) is socketed with successively away from dynamic jaw (2) side at adjusting yoke (3) upper connecting rod fixed head (1), spheric seating (5), spring (6), spring bumper cover (7) and compression adjusting nut (8), sphere seat board (4) offers oil filler point, the dynamic jaw spring drag link mechanism be connected on dynamic jaw (2) is two covers, oil filler point on the sphere seat board (4) of the dynamic jaw spring drag link mechanism of two covers is connected with the oil pipe (9) of mutually ganging up, oil pipe (9) is connected with pump nozzle (10).This novel employing centralized lubrication device, makes to form oil film between spring base and spheric seating, thus the effective wearing and tearing reduced between contact surface, improves part service life.
Description
Technical field
The utility model relates to a kind of dynamic jaw spring drag link mechanism of band lubrication of jaw crusher, belongs to jaw crusher technical field.
Background technology
Jaw crusher is commonly called as jaw and breaks, by dynamic jaw with determine jaw two pieces of jaws and form crusher chamber, and 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 completes moving jaw plate by driven by motor bent axle and moves back and forth, and utilizes the extruding between moving jaw plate and quiet jaw to complete the fragmentation of material.In shattering process, the epimere of dynamic jaw is connected with bent axle, lower end is provided with the adjusting device regulating opening, the bracket of adjusting device is between adjustment oil cylinder and dynamic jaw, because of bracket and dynamic jaw with regulate the connection of oil cylinder without fixture, for preventing bracket from coming off from two contact points, be provided with spring drag link mechanism in the bottom of dynamic jaw, in dynamic jaw movement process, spring drag link mechanism has also needed flexible and wobbling action.Existing jaw crusher spring drag link mechanism uses spring base to coordinate with spheric seating for realizing swinging, this mechanism cannot lubricate again due to close contact between spring base and spheric seating, cause easy abrasion between contact surface to damage, affect the result of use of jaw crusher.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of lubrication convenient, wear and tear little, and the dynamic jaw spring drag link mechanism of band lubrication of oiling jaw crusher easily, can overcome the deficiencies in the prior art.
The technical solution of the utility model is: the dynamic jaw spring drag link mechanism of band lubrication of jaw crusher, it comprises pull bar fixed head and dynamic jaw, the through hole of pull bar fixed head is inserted with adjusting yoke, sphere seat board is socketed with successively away from dynamic jaw side at adjusting yoke upper connecting rod fixed head, spheric seating, spring, spring bumper cover and compression adjusting nut, sphere seat board offers oil filler point, the dynamic jaw spring drag link mechanism be connected on dynamic jaw is two covers, oil filler point on the sphere seat board of the dynamic jaw spring drag link mechanism of two covers is connected with the oil pipe of mutually ganging up, oil pipe is connected with pump nozzle.
The dynamic jaw spring drag link mechanism of band lubrication of above-mentioned jaw crusher, the oil filler point on sphere seat board is provided with thread, oil pipe is provided with the nut matched with thread.
Compared with the prior art, the utility model offers oil filler point on the sphere seat board of the dynamic jaw spring drag link mechanism of two covers, oil filler point on the sphere seat board of the dynamic jaw spring drag link mechanism of two covers is connected with the oil pipe of mutually ganging up, oil pipe is connected with pump nozzle, two covers so just can be made to move jaw spring drag link mechanism and to realize centralized lubrication, the injection of lubricating oil makes to form oil film between spring base and spheric seating, thus the effective wearing and tearing reduced between contact surface, improves part service life.Oil filler point on sphere seat board is provided with thread, oil pipe is provided with the nut matched with thread, facilitate the connection of oil pipe like this.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to schematic cross-section.
Detailed description of the invention
Embodiment 1: as shown in Figure 1, the lower end of dynamic jaw 2 is connected on pull bar fixed head 1 by the dynamic jaw spring drag link mechanism of two covers, the main body of spring drag link mechanism is adjusting yoke 3, adjusting yoke 3 is connected in the through hole on pull bar fixed head 1 by the mode inserted, and end and the dynamic jaw 2 of adjusting screw(rod) 3 are hinged, sphere seat board (4) is socketed with successively away from dynamic jaw (2) side at adjusting yoke (3) upper connecting rod fixed head (1), spheric seating (5), spring (6), spring bumper cover (7) and compression adjusting nut (8), for convenience of the sphere seat board (4) to the dynamic jaw spring drag link mechanism of two covers, the contact surface oiling of spheric seating (5), sphere seat board (4) offers oil filler point, oil filler point on the sphere seat board (4) of the dynamic jaw spring drag link mechanism of two covers is connected with the oil pipe (9) of mutually ganging up, oil pipe (9) is connected with pump nozzle (10), oil pipe 9 with the connected mode of the upper oil filler point of sphere seat board (4) is, oil filler point on sphere seat board (4) and pump nozzle (10) are provided with thread, oil pipe (9) is provided with the nut matched with thread, the connection of the oil filler point on oil pipe 9 and sphere seat board (4) can be shown by rotating nut.
