Embodiment mono-
Refer to Fig. 3-1, Fig. 3-2, the present invention discloses a kind of high inclination-angle coal-winning machine, described high inclination-angle coal-winning machineComprise Oil sucking device, hydraulic fluid tank, filter 1; Described Oil sucking device is arranged in hydraulic fluid tank, comprises fuel sucking pipe2, oil sucting valve 3, gravity mechanism 4. Described oil sucting valve 3 is connected with the straight joint 22 of fuel sucking pipe 2, fuel sucking pipe2 bent sub 21 is connected with the oil absorbing end of filter 1. Described fuel sucking pipe 3 is for rotatably flexible; DescribedGravity mechanism 4 is gravitation ball 4, can rotate by any circumference.
Described filter 1 comprises long filter core 11, long barrel shell 12, and long barrel shell 12 ends connect the curved of fuel sucking pipe and connect21, bent sub 21 can rotate around the inlet port axis 13 of filter 1.
On described oil sucting valve 3, gravity mechanism 4 is set. One side of gravity mechanism 4 is provided with gland 5, and gland 5 is logicalCross screw 6 fixing with oil sucting valve 3; Described gravity mechanism 4 is set between gland 5 and oil sucting valve 3. Gravity machineStructure 4 is because the effect of gravity makes oil sucting valve 3 least significant end in oil level all the time, to adapt to working face high inclination-angleThe variation of the coal-winning machine hydraulic fluid tank oil level that coal seam causes.
As shown in Fig. 4-1, Fig. 4-2, when high inclination-angle appears in working face of coal seam, coal-winning machine fuselage and horizontal line areCorresponding wide-angle tilt; The gravitation ball 4 that is installed on high inclination-angle coal-winning machine in hydraulic fluid tank Oil sucking device due toAction of Gravity Field rolls along hydraulic fluid tank bottom surface to hydraulic fluid tank lowermost end, and gravitation ball 4 drags oil sucting valve 3, gland simultaneously5, also simultaneously to the motion of hydraulic fluid tank lowermost end, because fuel sucking pipe 2 is rotatably flexible, oil sucting valve 3, gravityBall 4, gland 5, screw 6 are arrived hydraulic fluid tank lowermost end; Make the end of this Oil sucking device in oil levelEnd, has ensured normal oil suction.
Check valve 31 is installed on oil sucting valve 3: when pump oil suction, due to the effect of negative pressure, check valve is beaten automaticallyOpen oil suction; When pump quits work, check valve is in closed condition, prevents that oil pipe inner fluid from refluxing because of Action of Gravity FieldTo hydraulic fluid tank, avoid inlet line, filter to cause the suction sky of pump without oil.
In sum, high inclination-angle coal-winning machine and Oil sucking device thereof that the present invention proposes, solve mining steeply dipping coal seamTime coal-winning machine heighten the oil suction problem of pump. This Oil sucking device is connected with fuel sucking pipe at filter oil absorbing end, fuel sucking pipeThe other end is connected with oil sucting valve, and oil sucting valve place is connected with gravitation ball, and gravitation ball orders about oil sucting valve and is positioned at all the time fuel tankThe least significant end of oil level, guarantees the normal oil suction of pump; Thereby the reliability that has greatly improved coal-winning machine, has ensured coal miningThe exploitation of machine high efficiency.
