Abstract
The utility model relates to a jaw crusher, and belonging to the mechanical crusher class; the jaw crusher is composed of a machine frame, a hopper fixed with the upper part of the machine frame, four bearing seats, two eccentric shafts, a moving jaw and a toothed plate hung on the eccentric shaft, a knee plate on the back face on the lower part of the moving jaw, a supporting regulator composed of a support frame, a screw bolt nut and a knee plate seat, a tensioning mechanism composed of a long screw bolt, the screw nut and a spring, gears arranged on the same end of two eccentric shafts, a driving mechanism composed of a belt wheel and an inertial wheel which are arranged on the other end of the eccentric shaft; the surface of the toothed plate adopts curved-shaped, the two gears are in the shape of the Chinese character 'ren', and the driving angle of the gear is positive 63 DEG; the both ends of the knee plate are wide and thick, and the middle part of the knee plate is narrow and thin.
Description
The utility model belongs to the mechanical crusher class.
To jaw crusher, the jaw crusher design and the maintenance of publishing in 9 years " the detailed argumentation of contrasting in the book; its structure is by frame; be fixed on the hopper on the frame; be fixed on four bearing blocks of upper rack; two eccentric shafts of bearing block support; each eccentric shaft is respectively to be hung with the jaw that a moving jaw and moving jaw are equipped with previously, the bracket that be equipped with at each back side, moving jaw bottom, with the corresponding supporting regulator of forming by support and bolt and nut and bracket seat of each bracket, the strainer of forming by long bolt and nut and spring that articulates in moving jaw lower end, the belt pulley that the meshing gear that two eccentric shafts are equipped with end and the eccentric shaft other end are equipped with and the transmission mechanism of the firelight or sunlight composition of inertia are formed, the structure to jaw formula high energy crusher of Chinese patent 94228021.0 the structure to jaw crusher above-mentioned with it is basic identical, different is: one, tooth plate is symmetrical broken line shape, be divided into thick in thin three reduction stages.Two, two eccentric shafts are two helical gears with the meshing gear of holding dress.Three, the drive line angle of bracket and moving jaw is positive 60 degree.Four, bracket is the thin-walled drum-type structure.The problem of above-mentioned disintegrating machine is: two tooth plates are broken line shapes, crusher chamber are formed have in level thick thin three sections, and the angle of engagement of tooth plate is bigger in the variation of each section, is unfavorable for that the smooth and easy naturally of material moves down, and also is unfavorable for stinging material.Two, two eccentric shafts are helical gears with what hold dress, though helical gear and spur gear compare the vibratility that alleviates disintegrating machine certain positive role are arranged, but still can not well overcome the vibratility of disintegrating machine.Three, the drive line angle of bracket and moving jaw is positive 60 degree, and some is less than normal, and is bigger than normal to the effect component of eccentric shaft.Four, bracket is the thin-walled drum-type structure, with this double as safety device, but the thin-walled drum-type structure, processing is difficulty relatively.
The purpose of this utility model is: provide that a kind of stepless fragmentation, vibratility are little, little to eccentric shaft effect component, bracket processing is saved trouble and safe and reliable to jaw crusher.
Technical measures of the present utility model are: with by frame, be fixed on the hopper of upper rack, be fixed on four bearing blocks of upper rack, two each eccentric shafts of eccentric shaft of bearing block support are hung with a moving jaw respectively and move the tooth plate that jaw is equipped with previously, the bracket that be equipped with at each back side, moving jaw bottom, with the corresponding supporting regulator of forming by support and bolt and nut and bracket seat of each bracket, the strainer of forming by long bolt and nut and spring that articulates in moving jaw lower end, the disintegrating machine that the transmission mechanism that belt pulley that the meshing gear that two eccentric shafts are equipped with end and the eccentric shaft other end are equipped with and flying wheel are formed is formed is the basis; The tooth plate surface is curved, and two meshing gears are double helical spurgears, and the drive line angle of bracket and moving jaw is positive 63 degree, and bracket is the narrow thin type in generous centre, two ends.
Disintegrating machine of the present utility model has stepless fragmentation, little, stressed less, the easy safe and reliable good effect of bracket making of eccentric shaft of vibratility.
Fig. 1 is a structural representation of the present utility model, and Fig. 2 is a side view.
Drawing explanation and embodiment are described as follows.11 is frames among the figure, is fixed with 12, four bearing blocks 12 of four bearing blocks at upper rack and is supporting two eccentric shafts 13, diaxon parallel arrangement; Each eccentric shaft 13 is hung with a moving jaw 2 respectively, tooth plate 1 is equipped with in the front of moving jaw 2, the surface of tooth plate 1 is curved, stepless fragmentation that can be from coarse to fine to material, it is more suitable that the angle of engagement b of two relative tooth plates 1 adopts about 25 degree, angle of engagement b is excessive to sting incessantly material, too smallly makes the outlet of hopper 15 less again, and production efficiency descends.There is bracket 3 at each back side, moving jaw 2 bottom, and the drive line angle α of bracket 3 and moving jaw 2 adopts positive 63 degree for well, can make the stressed of eccentric shaft 13 become little like this.The horizontal sextant angle C of bracket 3 adopts ten to 15 degree for well, can make jaw and tooth plate lower horizontal stroke value little, favourable in small, broken bits.Bracket 3 adopts the narrow thin type in generous centres, two ends, and the double as safety device can fracture from the centre when excessive when stressed, and to reach the purpose of protection disintegrating machine, the bracket of this shape has than thin-walled drum-shape bracket makes safe and reliable effect easily.Two eccentric shafts 13 are the secondary transmission with the gear 14 that end is equipped with, and gear 14 adopts double helical spurgear better, compares stable drive with helical gear the vibratility of disintegrating machine is obviously diminished, and simultaneously the axial force that overcomes disintegrating machine is had obvious effects.What the same end of two eccentric shafts 13 was adorned is that two double helical spurgears 14 are as the secondary transmission, what the other end of two eccentric shafts 13 was adorned respectively is belt pulley 17 and flying wheel, the small belt pulley of belt pulley 17 and motor is as the one-level transmission, what another eccentric shaft 13 ends were adorned is flying wheel, can make the more steady of broken motor-driven commentaries on classics.With the corresponding supporting regulator of being made up of support 9 and screw rod 8 nuts and bracket seat 4 of each bracket 3, adjusting screw(rod) 8 changes the spacing of two moving jaw 2 lower ends, so that the material of the granularity that obtains to vary in size.In order to reach bigger adjustable range, between bracket seat 4 and support 9, can be added with and regulate parallels 10.What articulate in the lower end of each moving jaw 2 is the strainer of long bolt 5 and nut 7 and spring 6 compositions.For the safety of producing, can be added with guard shield 16 in the outside of two herringbone bears 14.Convenience for the transportation that makes disintegrating machine can be equipped with suspension ring 18 on the frame 11 of hopper 15 both sides.
