Abstract

The utility model relates to a multi-function compound pendulum jaw crusher, which is composed of a rigid crusher body, a plane safe thrust plate with a tooth inlay type and a box seat; a rotary fixed jaw plate in the rigid crusher body is hinged to the rigid body through a pin shaft; one end of the plane safe thrust plate with a tooth inlay type is movably hinged with a connecting rod of a moving jaw through the pin shaft and a wear-resistance lining, and the other end of the plane safe thrust plate with a tooth inlay type is pressed on a tooth inlay seat through a nut and a spring sheathed on a bolt, and the box seat is an oscillation mechanism which is composed of an eccentric connecting rod, a bolt rod, a swing sieve and a hanging oscillation rod. The oscillation size can be used for regulating the bolt rod to carry out sieving crushed objects in a three-stage grain size mode.

Description

Multi-function jaw crusher

The utility model relates to a kind of single toggle jaw crusher that can once finish the thickness crushing and screening to the solid brittle material.

Existing single toggle jaw crusher divides coarse crushing and two kinds of types in small, broken bits on the function, ip angle (angle of nip) can not change, all not for screening mechanism.This disintegrating machine when crushing operation, ball-and-socket place, thrust plate two serious wear, noise is big, needs often to change, meeting by chance can not broken thing, or the excessive safe thrust plate of crushing force fractures, and can not continue to use.

The utility model purpose is, multi-functional single toggle jaw crusher after a kind of improve is provided, it can change ip angle and carry out coarse crushing or operation in small, broken bits, and can once finish three grades of screenings according to the hardness and the granularity needs of material, this machine is easy to use, save power consumption, safe and reliable, noiselessness, the castellated thrust plate in permanent plane need not to change, and the big I regulated at will of swing sieve aperture order is used.

Referring to accompanying drawing

Fig. 1 is the utility model vertical structure schematic diagram

Fig. 2 is the castellated safe thrust plate longitudinal sectional drawing in the utility model plane.

Multi-functional single toggle jaw crusher described in the utility model is by the rigidity body, and the castellated safe thrust plate in plane, block three parts are formed, and rotatable decide jaw (5) hinged by bearing pin (1) and rigidity body (2); Castellated safe thrust plate (14) one ends in plane are pressed on the tooth embedding seat (16) with moving jaw connecting rod (12) by lubricated bearing pin (15), anti-wearing liner (13); 7 ° of the adjustable ip angles of wedge head (3) of rigidity body (2) one sides are also fixing by fastening bolt (4); Discharge gate on the plane tooth embedding safety thrust plate (14) is made up of rectangular thread post (19), Thrust nut (17), hold-down nut (18), threaded post (19) one ends have free bearing to be movably hinged with tooth embedding seat (16) by bearing pin (15), the anti-wearing liner (13) of oilhole, rectangular thread post (19) can adopt trapezoidal thread, saw-tooth thread; The eccentric ratio swing mechanism that block (26) is made up of eccentric ratio (22), tightening latch (23), oscillating riddle (24), suspension fork (25), eccentric ratio (22) one ends are fixed on the flywheel eccentric shaft (10), the other end is fixed on the tightening latch (23), the two ends of oscillating riddle (24) are separately fixed at and hang on the fork (25), the upper end of tightening latch (23) is fixed on oscillating riddle (24) edge, can promote the swing of oscillating riddle.

Further describe and attached most preferred embodiment below in conjunction with accompanying drawing

Multi-functional single toggle jaw crusher described in the utility model, it is rotatable that decide jaw (5) hinged by bearing pin (1) and rigidity body (2), make the disintegrating machine ip angle become big or diminish, with decision coarse crushing or operation in small, broken bits, ip angle is transferred to the desired position, and tight a bolt (4) make rotatable jaw (5) location of deciding.Motor (21) moving flywheel (8) of generation rotates, and flywheel (8) is fixed on the eccentric shaft (10), makes jaw connecting rod (7) and moving jaw plate (6) do the attrition crushing motion by bearing (9).Castellated safe thrust plate (14) one ends in plane are hinged with moving jaw connecting rod (7) by bearing pin (15), anti-wearing liner (13), the other end is connected with tooth embedding seat (16) tooth embedding, the bolt that is fixed on the tooth embedding seat (16) is with spring (12), holddown spring (12) tooth embedding power increases, trip spring (12) tooth embedding power reduces, thereby has determined the thrust size of plane tooth embedding thrust plate (14).During crushing operation, when running into can not broken object the time the stressed unexpected increase of the castellated thrust plate in plane (14), the upwards component that tooth embedding power produces then backs down the pressure of spring (12) automatically, changes that tooth is clamped to be put, and increases pusher mouth gap, discharge can not broken thing, guarantees device security.Under the state of shutting down; change that tooth is clamped to be put; but also coarse adjustment discharge gate gap; the discharge gate adjusting device adopts rectangle, trapezoidal or zigzag double-screw bolt adjusting device; unclamp hold-down nut (18); rotation leans against the Thrust nut (17) on the rigidity body (2), can move forward and backward threaded post (19), to regulate the gap of discharge gate.Bearing pin (15), anti-wearing liner (13) and tooth embedding seat (16) are hinged.Bearing pin (15) has the oilhole that leads to anti-wearing liner (13), with the metal impact noise that reduces wear and thrust plate produces when eliminating work.For eliminating the dynamic stress that produces when moving jaw connecting rod (7) is worked, between rigidity body (2) and moving jaw connecting rod (7), be provided with spring tensioning means (20).Utilize moving jaw connecting rod (7), moving jaw plate (6) with decide the not backward position of attrition crushing of jaw (5).Motor (21) generation moving flywheel (8) and eccentric shaft (10) spindle nose on fixing eccentric ratio (22), in its generation, moved tightening latch (23), the fixing oscillating riddle (24) of suspension fork (25) of block swing mechanism, the size of the amplitude of oscillation can be regulated tightening latch (23) and be made broken object carry out the screening of three grades of granularities.
