The specific embodiment
As shown in the figure, the utility model is by fixed support 1, travel(l)ing rest 5, main falsework 6, oil cylinder 2, motor 3,8,10, gearbox 7, slush pump 9, drilling rod 13, assembly pulley 11,14, hoist engine 4, wire rope 15 compositions such as grade.On the main falsework 6 chute board 16 is set, the chute board angle is 135 °, chute board is provided with slotted hole and circular hole, be socketed in respectively in the rotating shaft 29,30 on fixed support 1 and the travel(l)ing rest 5, rotating shaft 29 can be movable in the chute board slotted hole, be welded with two fixedly sliding sleeves 20 on the fixed support, be enclosed within respectively on the column of travel(l)ing rest; The termination of travel(l)ing rest and oil cylinder 2 is hinged, cylinder shell is connected with fixed support, gearbox 7 and slush pump 9 are connected by flange, and be installed on the main falsework by sliding sleeve 12, the hollow shaft lower end of gearbox output is connected with drilling rod 13, the inlet of slush pump 9 is aimed in the upper end, and wire rope hoist 4 on assembly pulley 11,14 fixed bracket body is set on the main falsework, and assembly pulley is connected by wire rope 15 with hoist engine.
When oil cylinder piston bar 2 moves downward, movable support body 1 moves down along the fixedly sliding sleeve 32 on the fixed support, force main falsework 90 degree upsets by the chute board 16 on rotating shaft and the main falsework, reach the duty of drilling well, and the segment distance that can continue downwards to move both vertically, length is decided by the slotted hole of chute board, and fixed support is fixed on the tractor.
Motor 8 is installed on the gearbox 7, drives hollow shaft by double reduction and rotates, and hollow shaft lower end and drilling rod 13 are connected by flange; The inlet of slush pump 9 is aimed in the gearbox upper end, slush pump is made up of housing 21, deslagging chamber 24, mud discharge connection 26, deslagging chamber is connected with mud discharge connection 26 by moving flange plate 25, sealing plate 23 is set between deslagging chamber and the housing, 22 is gasholder, end cap 17 is set on the housing, impeller 18 is housed in the housing, motor 10 is connected with the impeller 18 of slush pump by flange 19, directly driving slush pump rotary flange 19 1 is to play the effect that connects motor, the 2nd, play the effect of the sealing pump housing; Slush pump, gearbox, drilling rod are arranged on the same axis, by sliding sleeve 12, utilize assembly pulley and wire rope 15, under the driving of hoist engine 4, have realized this integral part sliding up and down on main falsework.
The effect of sealing plate 23 and gasholder 22 is when the airtight outlet of sealing plate, and the admission pipe of diesel engine or gasoline engine is connected the air of realizing the sucking-off down-hole and makes in the mud suction pump on the adapter by gasholder and the tractor.The 24th, the big rock ballast of suction can be removed in the deslagging chamber.Moving flange plate 25 can be adjusted the angle of spoil disposal stone outlet easily.Utilize the diesel engine of tractor or the admission pipe of gasoline engine to link in the gasholder adapter of slush pump, make the whole system sealing, air sucking-off with the down-hole, reach vacuum state, force mud to rise in the slush pump, open closing valve this moment, and slush pump can be worked smoothly, and mud is extracted out from the shaft bottom.
Have a circular hole on the work top of described travel(l)ing rest 2, the circular hole edge is provided with two sections arc plates 27, forms two elongated slots 28, drilling rod one end is provided with boss, and the boss of drilling rod termination matches with elongated slot on the arc plate, fixedly drilling rod, by the rotating of drilling rod, realize the dismounting of drilling rod.
