The axial width gradual change of described adjustment voussoir, adjustment voussoir moves axially by external force, and the support direction of the adjustment moving direction of voussoir and bracket is perpendicular; When adjusting voussoir and moving axially, adjustment voussoir forces bracket seat to move along the support direction of bracket.Specifically when implementing, adjustment voussoir 64 is preferably two pieces, the cross section all at right angles triangle of two pieces of adjustment voussoirs 64, and two pieces of adjustment voussoirs 64 are arranged in opposite directions and inclined-plane is smooth offsets, and adjusts voussoir and backing plate is also smooth offsets.The end (narrow limit, right angle) of adjustment voussoir 64 is connected with adjustment oil cylinder through bracket frame groove 33 side, regulates oil cylinder by hinge at adjustment oil cylinder seat, regulates hydraulic oil cylinder driving adjustment voussoir to move axially; Export by regulating oil cylinder and replace manual adjustment, not only facilitate, and be conducive to the fine adjustment of discharging opening.
Above-mentioned adjusting mechanism for discharging hole is for regulating dynamic jaw group 5 and determining discharging opening 92 size between jaw frame 2, it adjusts two pieces of positions adjusted between voussoir 64 particular by regulating oil cylinder, if move toward one another between two pieces of adjustment voussoirs 64, two pieces of adjustment voussoirs 64 extrude outward, successively by backing plate 63, bracket seat board 62, bracket seat 61, bracket 65 and dynamic jaw bracket seat 522, to move jaw group 5 lower end near determining jaw frame 2 lower end, discharging opening 92 diminishes; If two pieces adjustment voussoirs 64 between counter motion; two pieces adjustment voussoirs 64 the minimizing that takes up space, originally the backing plate 63 of racking jaw group 5, bracket seat board 62, bracket seat 61, bracket 65 and dynamic jaw bracket seat 522 meeting travelling backwards under the gravitational force urges of dynamic jaw group 5 is propped up, now dynamic jaw group 5 lower end is away from determining jaw frame 2 lower end, and discharging opening 92 becomes large.
dynamic jaw tension buffer gear
Described dynamic jaw tension buffer gear comprises the drawing cylinder seat be arranged in frame, and is arranged on the drawing cylinder 71 on drawing cylinder seat.Described drawing cylinder seat comprises cylinder rack 72 and bearing block 73, and the upper end of bearing block 73 is by hinge in cylinder rack 72, and bearing block 73 inner position is provided with supporting bearing 74, and supporting bearing 74 positioned internal is provided with bearing rotating shaft 75; The end of drawing cylinder 71 is fastened in bearing rotating shaft 75, and the output shaft of drawing cylinder 71 is hinged in dynamic jaw group 5.
Above-mentioned dynamic jaw tension buffer gear for straining dynamic jaw group 5 lower end, the amplitude of fluctuation of limit brake jaw group 5, can anti-stop jaw group 5 swing excessive with determine jaw frame and collide, and dynamic jaw group 5 swung ambassador's bracket and to drop both of these case generation.And when equipment runs, drawing cylinder 71 can move along with the swing of dynamic jaw group 5, the output shaft of drawing cylinder 71 can stretch among a small circle on the one hand, plays cushioning effect; Drawing cylinder 71 is due to the change of its outbound course on the other hand, can along its hinged place, end, and the bearing pin between bearing block 73 and cylinder rack 72 carries out oscillation adjustment, the hinged structure of secondary is conducive to the output area expanding drawing cylinder 71, is more conducive to protection drawing cylinder 71 high frequency wobbles and damages.In addition, if do not arrange supporting bearing 74 under this structure, the two ends wearing and tearing of bearing rotating shaft 75 can be very serious, and its possibility of result can shine into bearing rotating shaft 75 and fracture, or the temperature of shining into bearing rotating shaft 75 too high after pass to drawing cylinder 71, to make in oil cylinder oil temperature raise thus damage oil cylinder; Then can reduce the unnecessary wearing and tearing in bearing rotating shaft 75 two ends by arranging supporting bearing 74, controlling wearing and tearing and bringing heating and the danger fractureed.
summary
The jaw crusher of comprehensive said structure, this disintegrating machine determine the interior forward end that jaw frame is arranged on frame main body, bracket frame is arranged on the Internal back end of frame main body, dynamic jaw group is arranged in the frame main body of determining between jaw frame and bracket frame, drive train is fixed on bracket frame rear end, is connected between drive train with dynamic jaw group by belt transmission; Adjusting mechanism for discharging hole and dynamic jaw tension buffer gear are arranged on frame main body inside, and adjusting mechanism for discharging hole is for regulating crusher chamber discharging opening size, and dynamic jaw tension buffer gear is for limitting the amplitude of fluctuation of brake jaw group.During equipment work, the dynamic jaw shaft assembly that drive motors is moved in jaw group by belt drive rotates, that moves the eccentric shaft in jaw shaft assembly rotates through the swing that inner self-aligning roller bearing is converted into dynamic gnathosoma, moves gnathosoma bottom and determines the jaw mouth being configured for broken building stones between jaw frame bottom; Building stones to be processed then enter in crusher chamber by the charging aperture of crusher chamber upper end, are extruded, broken at dynamic gnathosoma and the jaw mouth place determined between jaw frame, are then discharged by discharging opening.
