Referring to Fig. 4～Fig. 8, the utility model embodiment comprises and adjusts oil cylinder 1a No. one, adjusts oil cylinder 1b for No. two, hydraulic cylinder carriage 2a, No. two hydraulic cylinder carriage 2b, pin 3, accumulator fixed support 4, accumulator 5, hydraulic cylinder joint 6, drawing cylinder 7, bolt 8, pin 9, turning arm 10, hydraulic cylinder carriage 11, sliding seat 12, pressure arm 13, pressure arm seat 14, pressure arm saddle 15, pad 16, adjusts skewback 17a No. one, adjusts skewback 17b, spacer 18, pin 19, pin 20, frame 21 for No. two.
One end of pressure arm 13 and sliding seat 12 are fixing, and the other end and pressure arm seat 14 are fixing.Pressure arm seat 14 is fixing with pressure arm saddle 15.Sliding seat 12 is connected with the discharge gate device of jaw crusher.
A hydraulic cylinder carriage 2a and No. two hydraulic cylinder carriage 2b use the screw relative fixed in frame 21 both sides.
The rod chamber end of adjusting oil cylinder 1a for No. one is connected with an adjustment skewback 17a by pin 20, and the rodless cavity end is connected with a hydraulic cylinder carriage 2a by pin 19, spacer 18.The rod chamber end of adjusting oil cylinder 1b for No. two is connected with No. two adjustment skewback 17b by pin, and the rodless cavity end is connected with No. two hydraulic cylinder carriage 2b with spacer by pin.Adjust oil cylinder 1a for No. one and adjust oil cylinder 1b for No. two and be oppositely arranged.An adjustment skewback 17a and No. two adjustment skewback 17b are oppositely arranged, and the inclined-plane 17a1 of an adjustment skewback 17a contacts cooperation with the inclined-plane 17b1 of No. two adjustment skewback 17b.Form the gap that can hold pad 16 between the back side 17b2 of No. two adjustment skewback 17b and the pressure arm saddle 15, pad 16 is inserted in this gap, can select suitable pad 16 as required.The back side 17a2 that adjusts skewback 17a for No. one contacts with frame 21.
The rod chamber end of drawing cylinder 7 is connected with sliding seat 12 by hydraulic cylinder joint 6, pin 3, and the rodless cavity end passes through bolt 8 and is connected with turning arm 10.Turning arm 10 is connected with hydraulic cylinder carriage 11 by pin 9.Hydraulic cylinder carriage 11 is fixed on frame 21 bottoms by screw.That is to say that the rodless cavity end of drawing cylinder 7 is connected with frame 21 with hydraulic cylinder carriage 11 by turning arm 10.
Accumulator 5 is fixing by accumulator fixed support 4 by bolt, and is communicated with by the rod chamber of oil pipe with drawing cylinder 7.Accumulator fixed support 4 is screwed frame 21 bottoms.Drawing cylinder 7 plays tension, unclamps the effect of pressure arm 13.5 pairs of drawing cylinders 7 of accumulator play the pressurize effect.
When adjusting discharge gate, at first unclamp pressure arm saddle clamping screw, start the regulator solution pressing system, making hydraulic oil act on No. one adjusts oil cylinder 1a and adjusts oil cylinder 1b No. two, adjust two of the flexible promotions of oil cylinder 1a and No. two adjustment oil cylinder 1b for No. one and adjust the skewback move left and right, thereby two adjustment skewback gross thickness are changed, cause that simultaneously pad 16, pressure arm saddle 15, pressure arm seat 14, pressure arm 13 and sliding seat 12 fore-and-aft directions move, and have adjusted the size of discharge gate effectively.
As shown in Figure 8, the concrete control mode of the utility model full-hydraulic adjustment device: this hydraulic system is the polyphone loop, is made up of discharge gate adjustment loop and pressure arm tension loop.Discharge gate is adjusted the stretching out or withdraw of piston rod that No. of circuit controls discharge gate is adjusted oil cylinder 1a and adjusted oil cylinder 1b for No. two, and pressure arm tension circuit controls drawing cylinder 7 makes pressure arm 13 strain or unclamp.
When jaw crusher is in normal operating conditions, solenoid directional control valve F3, solenoid directional control valve F4 are in meta, position, a solenoid check valve F5 left side is connected, the hydraulic oil of gear pump F1 output flows back to fuel tank through check valve F2, solenoid directional control valve F3 and solenoid directional control valve F4, oil filter F6, the gear pump off-load, adjust oil cylinder 1a for No. one and adjust oil cylinder 1b for No. two and keep original position, drawing cylinder 7 rod chamber pressurizes.When owing to leak, when drawing cylinder 7 rod chamber pressure dropped to pressure switch F8 set pressure X MPa, solenoid directional control valve F4 changed to position, a left side, gives drawing cylinder 7 rod chamber repairings, drawing cylinder 7 rod chamber pressure raise, when pressure was increased to pressure switch F8 set pressure X+1.7MPa, solenoid directional control valve F4 got back to meta, the gear pump off-load, drawing cylinder 7 rod chamber pressure descend, when dropping to X MPa, solenoid directional control valve F4 changes again to position, a left side, gives drawing cylinder 7 rod chamber repairings.Move in circles like this, remain drawing cylinder rod chamber pressure between X-X+1.7MPa, pressure arm 13 is in tension all the time.
When needs are adjusted discharge gate, at first solenoid directional control valve F4 changes to right position, solenoid check valve F5 changes simultaneously to right position, the hydraulic oil of gear pump F1 output enters drawing cylinder 7 rodless cavities through check valve F2, solenoid directional control valve F3, solenoid directional control valve F4, the oil of drawing cylinder 7 rod chambers flows back to fuel tank through solenoid check valve F5, solenoid directional control valve F4, oil filter F6, drawing cylinder 7 piston rods stretch out, and unclamp pressure arm 13.Solenoid directional control valve F3 changes to position, a left side or right position then, and solenoid directional control valve F4 changes to meta.The hydraulic oil of gear pump F1 output enters rod chamber or the rodless cavity of adjusting oil cylinder 1a and adjusting oil cylinder 1b for No. two for No. through check valve F2, solenoid directional control valve F3, and the hydraulic oil of adjusting oil cylinder 1a No. one and adjusting oil cylinder 1b rodless cavity or rod chamber for No. two flows back to fuel tank through solenoid directional control valve F3, solenoid directional control valve F4, oil filter F6.This moment is because solenoid check valve F5 is in right position, the rod chamber of drawing cylinder 7 and rodless cavity intercommunication and logical oil return, so when adjusting oil cylinder 1a No. one and adjusting oil cylinder 1b for No. two when flexible, drawing cylinder 7 is adjusted oil cylinder 1a and adjusts oil cylinder 1b for No. two flexible simultaneously with No. one.After the discharge gate adjustment finished, solenoid directional control valve F3 got back to meta, solenoid check valve F5 gets back to position, a left side, and solenoid directional control valve F4 changes to position, a left side simultaneously, drawing cylinder 7 rod chamber oil-feeds, tension pressure arm 13.Solenoid directional control valve F4 gets back to meta when drawing cylinder pressure is elevated to pressure switch F8 set pressure X+1.7Mpa.
Overflow valve F7 is the Adjustment System operating pressure among the figure, when system works pressure during greater than X+2MPa overflow valve F7 connect, the hydraulic oil of a part of gear pump F1 output flows back to fuel tank through overflow valve F7, oil filter F6, reduces system works pressure.
In addition, need to prove, the specific embodiment described in this specification, its zero, the shape of parts, institute's title of being named etc. can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection domain of the utility model patent according to the utility model patent.
