The axial width gradual change of described adjustment voussoir, adjusting voussoir can be moved axially by external force, and the moving direction adjusting voussoir is perpendicular with the support direction of bracket；When adjusting voussoir and moving axially, adjust voussoir and force bracket seat to move along the support direction of bracket.Specifically when implementing, adjusting voussoir 64 and be preferably two pieces, two pieces of cross section all at right angles trianglees adjusting voussoirs 64, two pieces adjust voussoir 64 and are oppositely arranged and inclined-plane is smooth offsets, and adjust that voussoir is the most smooth with backing plate to offset.There is regulation oil cylinder the end (narrow limit, right angle) adjusting voussoir 64 through bracket frame groove 33 side connection, and regulation oil cylinder is moved axially at regulation oil cylinder seat, regulation hydraulic oil cylinder driving adjustment voussoir by hinge；Replace manual adjustment by regulation oil cylinder output, not only facilitate, and beneficially the accurate of discharging opening regulates.
Above-mentioned adjusting mechanism for discharging hole is for regulating dynamic jaw group 5 and discharging opening 92 size determined between jaw frame 2, it adjusts two pieces of positions adjusted between voussoir 64 particular by regulation oil cylinder, if two pieces adjust move toward one another between voussoir 64, two pieces adjust voussoir 64 and extrude outward, pass sequentially through backing plate 63, bracket seat board 62, bracket seat 61, bracket 65 and dynamic jaw bracket seat 522, by dynamic jaw group 5 lower end near determining jaw frame 2 lower end, discharging opening 92 diminishes；If two pieces adjust adverse movement between voussoirs 64, two pieces adjust voussoirs 64 and are taken up space minimizing, originally a backing plate 63 of racking jaw group 5, bracket seat board 62, bracket seat 61, bracket 65 and dynamic jaw bracket seat 522 can move back under the gravitational force urges of dynamic jaw group 5, now moving jaw group 5 lower end away from determining jaw frame 2 lower end, discharging opening 92 becomes big.
Dynamic jaw tension buffer gear
Described dynamic jaw tension buffer gear includes the drawing cylinder seat being arranged in frame, and the drawing cylinder 71 being arranged on drawing cylinder seat.Described drawing cylinder seat includes 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 is used for straining dynamic jaw group 5 lower end, the amplitude of fluctuation of limit brake jaw group 5, be possible to prevent dynamic jaw group 5 swing excessive with determine the collision of jaw frame, and dynamic jaw group 5 swung ambassador's bracket and dropped both of these case generation.And when equipment runs, drawing cylinder 71 can move along with the swing of dynamic jaw group 5, on the one hand the output shaft of drawing cylinder 71 can carry out little scope stretching, plays cushioning effect；On the other hand drawing cylinder 71 is due to the change of its outbound course, can be along its hinged place, end, and the bearing pin between bearing block 73 and cylinder rack 72 carries out oscillation adjustment, the output area of the structure beneficially expansion drawing cylinder 71 that secondary is hinged, is more beneficial for protecting drawing cylinder 71 high frequency wobbles and damaging.Additionally, without arranging supporting bearing 74 under this structure, the two ends abrasion of bearing rotating shaft 75 can be very serious, and its result may be shone into bearing rotating shaft 75 and be fractureed, or the temperature of shining into bearing rotating shaft 75 too high after pass to drawing cylinder 71, make oil temperature in oil cylinder raise thus damage oil cylinder；Then can reduce, by arranging supporting bearing 74, the abrasion that bearing rotating shaft 75 two ends are unnecessary, control the danger that abrasion brings heating and fractures.
Summary
The jaw crusher of summary structure, the jaw frame of determining of this disintegrating machine is arranged on the interior forward end of 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 determined between jaw frame and bracket frame, drive train is fixed on bracket frame rear end, is connected by belt transmission between drive train with dynamic jaw group；Adjusting mechanism for discharging hole and dynamic jaw tension buffer gear are arranged on inside frame main body, and adjusting mechanism for discharging hole is used for regulating crusher chamber discharging opening size, and dynamic jaw tension buffer gear is for limiting the amplitude of fluctuation of brake jaw group.During equipment work, the dynamic jaw shaft assembly driving motor to move in jaw group by belt drive rotates, the internal self-aligning roller bearing that rotates through of the eccentric shaft in dynamic jaw shaft assembly is converted into the swing of dynamic gnathosoma, moves gnathosoma bottom and determines the jaw mouth constituted between jaw frame bottom for crushing building stones；Building stones to be processed are then entered in crusher chamber by the charging aperture of crusher chamber upper end, are extruded, crush, then discharged by discharging opening at dynamic gnathosoma and the jaw mouth determine between jaw frame.
