Description

The energy-conservation jaw crusher of high efficiency and high strength

The utility model belongs to the mechanical crusher class.

Jaw crusher, be the crushing mechanism that more extensively is used at present, the structure of this disintegrating machine is made up of the tensioned mechanism of the flywheel at limit backplate, fixed jaw, moving jaw and the moving jaw plate of frame, both sides, eccentric shaft, eccentric shaft two ends and belt pulley and two bearing blocks, bracket seat and adjusting devices, the bracket pad that is contained in bracket seat and moving jaw lower end, the bracket between two bracket pads, moving jaw lower jaw end.The problem of this disintegrating machine is that eccentric shaft is bearing and the bearing block support that relies on two ends, and two outboard bearing lids of two bearing blocks are to be screwed at the bearing block lateral surface, and is very inconvenient to the dismounting maintenance; Two outboard bearing lid inboards all have the bulge loop platform that leans bearing outer ring that eccentric shaft is positioned, and this remote location is difficult to overcome accumulated error, makes the roller unbalance stress of two bearings, easily heating, serious wear.The drive line angle inclination angle of external jaw is 45 degree in addition, and stressed reasonable inadequately, it is bigger to consume energy; Fixed tooth plate and frame bottom surface vertical fixing, the whereabouts of unfavorable material; Moving jaw upper shaft hole is higher than material inlet, makes the long consumption steel of jaw bigger.

The purpose of this utility model is: provide a kind of and make that two bearing rollers are stressed uniformly, long service life, power consumption is few, material falls smoothly, steel material consumption is few disintegrating machine.

Technical measures of the present utility model are: based on by the flywheel at the limit backplate of frame, both sides, solid moving jaw plate, moving jaw and moving jaw plate, eccentric shaft, eccentric shaft two ends and belt pulley and two bearing blocks, bracket seat and adjusting devices, be contained in the disintegrating machine that the tensioned mechanism of the bracket pad of bracket seat and moving jaw lower end, the bracket between the bracket pad, moving jaw lower end forms; Two outboard bearing lids of two bearing blocks are assemblied in the annular groove of bearing block; The outside of the bearing block in left side and inboard bearing cap all have the bulge loop platform that leans bearing outer ring; The outside of the bearing block on right side and inboard bearing cap and bearing outer ring leave the gap.

Disintegrating machine of the present utility model, because with the remote location between two bearings, change in the both sides of a bearing and closely locating, overcome easily because the unfavorable factor that the flexible influence that accumulated error and working environment are caused brings, guaranteed machinery turns round under normal clearance, improves the good effect of service life and easy disassembly and maintenance maintenance.

Fig. 1 is a structural representation of the present utility model, and Fig. 2 is a side view.

Fig. 3 is the schematic diagram of bearing block location.

Fig. 4 is the inclination angle schematic diagram of drive line angle.

Drawing explanation and embodiment are as follows: 9 is frames, the 2nd among the figure, the limit backplate, the 1st of both sides, and fixed jaw, the 7th, moving jaw, the 3rd, moving jaw plate, the 6th, flywheel 4 and belt pulley 15 and two bearing blocks the 5, the 12nd are equipped with in eccentric shaft, eccentric shaft 6 two ends, bracket seat, the 13rd, the adjusting device of bracket seat, the 10th, bracket pad, the 11st, bracket, the 14th, the tensioned mechanism of moving jaw lower end, above-mentioned is the composition structure of existing jaw crusher.The eccentric shaft of this disintegrating machine is bearing and bearing block 5 supportings that rely on two ends, and two outer hand hay cutter bearing caps 16 of two bearing blocks are the sides that are screwed at bearing block 5, and is very inconvenient to the dismounting maintenance; The bearing cap 16 in two outsides all has the bulge loop platform that leans bearing 17 outer rings that eccentric shaft is positioned, and this remote location is difficult to overcome accumulated error, makes the roller unbalance stress of two bearings 17 easily generate heat serious wear.The utility model is assemblied in two outboard bearings lid 16 of two bearing blocks 5 (see figure 3) in the annular groove of bearing block 5, and this structure can the easy disassembly and maintenance maintenance.The outside of the bearing block 5 in left side and inboard bearing cap 16 and 18 all have the bulge loop platform that leans bearing 17 outer rings; The outside of the bearing block on right side and inboard bearing cap and bearing outer ring leave the gap, structure by the remote location of two bearings becomes by an in-plant location structure of bearing, can overcome accumulated error and because of the work undesirable element that brings of influence that expands with heat and contract with cold, machinery can be turned round under the normal clearance situation all the time, can improve service life.Existing in addition jaw crusher also has following problems: the inclination angle A of the drive line angle of moving jaw is 45 degree, and the inclination angle is excessive, and is stressed reasonable inadequately, the big (see figure 4) of power consumption; The bottom surface vertical fixing of fixed tooth plate 1 and frame 9, the whereabouts of unfavorable material; The upper shaft hole of moving jaw 7 is higher than material inlet, makes jaw long, and steel consumption is big.Of the present utility model improving one's methods is: the inclination angle of the drive line angle of moving jaw 7 changes 30 to 35 degree into, preferably adopts 33 degree; Fixed tooth plate 1 flare 5 to 6 degree; The axis hole of moving jaw 7 and material inlet are on same level.
