Bottom mounted tube pendulum double chamber alligator
Bottom mounted tube pendulum jaw formula two-chamber disintegrating machine belongs to rock, the new type crushing machine of material fragmentations such as ore.
The existing jaw crusher of China mainly contains: two kinds of complex pendulum type jaw crusher and simple pendulum type jaw crushers.The complex pendulum type (see figure 2) is moved jaw swinging track complexity, and track becomes some sub-ellipticals, when moving jaw is swung work done, horizontal throw is compressed fragmentation to material, the vertical stroke of moving jaw makes liner plate produce strong slip grinding with storeroom simultaneously, and wear liner is fast, and the life-span only is the 1/4-1/5 of simple pendulum machine, and the power consume is big, dust rate height because moving jaw is done complicated swing, forces during backhaul material is retracted a segment distance, material is corresponding growth of holdup time in the jaw chamber, and productivity ratio is low.Letter pendulum type (see figure 3) is because the suspended axle of moving jaw is in the top of frame, and jaw chamber feed inlet end moves apart from little, and just the material that drops into can not be crushed to more fritter, so percentage of damage is low, is about 80% of physical pendulum formula productivity ratio.The discharge gate end moves apart from big, and broken thing particle size uniformity is poor, and easily forms fragmentation, with the material compacting and dissipation power.
The purpose of this utility model is in order to improve the swing form of moving jaw, makes jaw not have the backlash journey and a kind of novel bottom mounted tube pendulum jaw formula two-chamber disintegrating machine that designs.
Structure of the present utility model is by body, and actuating unit is decided jaw, and moving jaw etc. are partly formed.Actuating unit comprises big belt pulley, eccentric shaft, cylinder, bearing etc.; Deciding jaw comprises and decides jaw liner plate, backing plate; Moving jaw comprises moving jaw liner plate, bearing plate, voussoir.Between the quota of body two walls and body biside plate, form a back taper cavity, moving jaw is arranged in the chamber and forms two jaw chambeies, moving jaw lower end is bearing in to place by body biside plate and two decide on the bolster of center position below the back taper cavity that jaw forms, moving jaw is taked the form of simply swinging, around the bolster work done that swings, no backlash journey need not very big inertia force, saved flywheel gear, power is by the big belt pulley transmission.There is the cylinder chamber moving jaw upper end, the intrinsic bearing plate in the both sides in chamber, between the bearing plate of moving jaw cylinder one side one voussoir is housed, after bearing plate used wearing and tearing for a long time with cylinder, the gap was adjusted by voussoir, in eccentric shaft and the cylinder cylinder chamber between two bearing plates, off-centre when rotating along with eccentric shaft is moved distance, promotes cylinder and bearing plate, and moving jaw is just made left and right sides reciprocally swinging, material is carried out fragmentation, and the material grain is outside solid blow tank discharge machine on moving jaw.
Adopt the utility model to overcome the shortcoming of existing jaw crusher, moving jaw bolster underlying has improved the swing form of moving jaw, more meets the Fracture law of material, two jaw chambeies take turns to operate, moving jaw does not have the backlash journey, and productivity ratio increases substantially, and is higher than 1～1.5 times in physical pendulum machine.This motor-driven jaw does not almost have vertical stroke, and energy consumption is low, the liner plate long service life.Complete machine structure is simple, and compactness is convenient to make and working service, and required steel occupancy only is 30%～50% of existing disintegrating machine.
Figure of description, Fig. 1 are schematic diagram of the present utility model, and Fig. 2 is the schematic diagram of complex pendulum type jaw crusher, and Fig. 3 is the schematic diagram of simple pendulum type jaw crusher, and Fig. 4 is concrete structure figure of the present utility model.
(4) further specify realization of the present utility model now in conjunction with the accompanying drawings.It is to decide jaw liner plate (11) that jaw accent width adjusting backing plate (13) the backing plate outside is arranged on two walls about body (14), moving jaw (8) the left and right sides intrinsic moving liner plate of face (11), liner plate all adopts the ZGMn13 steel of high-wearing feature to make, and moving jaw lower end places the position, center, below of body with bolster (9).Moving jaw upper end is the cylinder chamber, two medial surfaces in chamber are equipped with bearing plate (3), the gap of being equipped with between one side bearing plate and the moving jaw cylinder after the long-term use of the same cylinder of a voussoir (2) bearing plate (4) is worn and torn is adjusted by voussoir (2), cylinder (4) connecting shaft holds the middle part that (5) are enclosed within eccentric shaft (6), bearing is equipped with at the two ends of eccentric shaft, bearing is through bearing box, be fixed on the body top, the external part of eccentric shaft, big belt pulley (1) is housed, and big belt pulley drives eccentric shaft along with the off-centre that eccentric shaft rotates is moved distance, promotes moving jaw and swings, material is broken in the jaw chamber, the material grain that has been broken, outside blow tank (12) discharge machine, side plate (10) is equipped with in the two side in jaw chamber, in case the body wearing and tearing, (7) are cover body.
