The hydraulic system of shown in Figure 30 gangue filling machine.This hydraulic system is an open circuit, by triple gear pump 70 fuel feeding, gear pump with water-cooled machine 72, be that M1 drives, its input passes through filter connected tank 49, is fuel tank assembly, export three road pressure oils, each pump one tunnel, the hydraulic motor of walking about supply, cylinder hydraulic motor, oil cylinder loop.Shared 13 three six logical hand-operated direction valves 85～97 are controlled in the loop.Three road oil supply loops are from left to right successively:
1. the first via connects cylinder hydraulic motor 59 through three six-way transfer valves 85; When this road is in stop position at reversal valve 85, can pass through reversal valve 85, in parallel with the second the tunnel.
2. the second the tunnel respectively by two three six- way transfer valves 86,87, are connected with left and right walking hydraulic motor 81,82.And, when first via oil circuit is in stop position at three six-way transfer valves 85, the 5th, six hydraulic fluid ports by this reversal valve 85, be working hole C, D, communicate and first and second feed flow loop is connected; That is: for the hydraulic oil of cylinder hydraulic motor 59 work, when cylinder hydraulic motor 59 is not worked, also can make crawler travel portion possess two kinds of speeds of travel, with convenient this gangue filling machine of transferring fast in the down-hole with the second the tunnel being left and right walking hydraulic motor 81,82 feed flows jointly.
3. Third Road be this machine by two 5-linked reversal valves respectively 16 oil cylinders, two groups of fuel feeding of branch.
1) first 5-linked reversal valve: five three six-way transfer valves 88～92 push away flat oil cylinder 38 with two impelling belt hoist cylinders 28, two impelling belt angling cylinders 17, impelling belt tension oil cylinder 31 and telescopic oil cylinder 32, two spoils respectively, two crawler belt tensioner oil cylinders 65 are connected.
2) second 5-linked reversal valve: five three six-way transfer valves 93～97 are connected with two leveling cyclinders 45, tuningout oil cylinder 52, the oblique oil cylinder 60 of accent, right back support cylinder 84, left back support cylinder 83 respectively.
By a group oil cylinder of first 5-linked reversal valve feed flow, mainly be that control impelling belt portion works; By a group oil cylinder of second 5-linked reversal valve feed flow, mainly be to control the work of material loading delivery section.Because when working in impelling belt portion, can influence the former work to the operation of material loading delivery section oil cylinder, so need to be taken measures in the feed flow loop of two 5-linked reversal valve groups, make the control of impelling belt portion its oil cylinder when operation, with the control interlocking of material loading delivery section oil cylinder.Concrete measure is:
Two 5-linked valves are by same oil pump feed flow, and the oil supply loop of the two series connection, oil return loop are independent separately.The 5th, six hydraulic fluid ports of five three six-way transfer valves 88～92 of first 5-linked reversal valve, be working hole C, D, communicate and be connected that the oil-out of five reversal valves is connected to same oil return loop with the bypass of feed flow loop at stop position.The connection of five three six-way transfer valves 93～97 of second 5-linked reversal valve also together.When any plate valve of first 5-linked reversal valve is worked, hydraulic oil is not by this reversal valve bypass and by second direct oil return of 5-linked reversal valve, second 5-linked reversal valve do not have hydraulic oil to supply with, when just can be implemented in the work of impelling belt portion, its each oil cylinder reversal valve 88～92 and each oil cylinder reversal valve 93～97 mutual locking of material loading delivery section, thus staff's maloperation avoided.
Establish hydraulic lock 98,99 in the loop between reversal valve 88 and two impelling belt hoist cylinders 28.Establish hydraulic lock 100 and two flow speed control valves in the loop between reversal valve 89 and two impelling belt angling cylinders 17.Establish hydraulic lock 101 in the loop between reversal valve 90 and impelling belt telescopic oil cylinder 32, tensioner oil cylinder 31.Establish hydraulic lock 102 in the loop between reversal valve 93 and two leveling cyclinders 45.Establish hydraulic lock 103 in the loop between reversal valve 94 and tuningout oil cylinder 52.Establish hydraulic lock 104 in the loop between reversal valve 95 and the oblique oil cylinder 60 of accent.Establish hydraulic control one-way valve in the loop between reversal valve 92 and the oblique oil cylinder 65 of accent.Inlet at reversal valve 88～97 is established one way valve.All the other have the fine filtering apparatus, the oil temperature sensor PT in the fuel tank 49, fuel level sensor PL, strainer in reducing valve, one way valve, pressure meter, oil return loop etc.
