In figure, 1: handle; 2: accumulator; 3: switch; 4: air duct; 5: high/low hydraulic fluid force feed interface; 6: hydraulic jack; 7: drainback passage; 8: air chamber; 9: piston sleeve; 10: spade positioning sleeve; 11: snap ring; 12: snap ring button; 13: dust outlet; 14: piston and piston rod; 15: air filter; 16: control valve; 17: broken shovel (drill rod).
Detailed description of the invention
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
Embodiment, as shown in Figure 1:
A kind of hydraulic crushing shovel, by tubular fuselage, the handle 1 that becomes " T " font to be connected with fuselage forms, it is characterized in that described fuselage is by being box type accumulator 2 from top to bottom successively, control valve 16, hydraulic jack 6, air chamber 8, piston sleeve 9, spade positioning sleeve 10 connects to form, also comprise removable broken shovel 17, described control valve 16 sides are provided with high/low pressure hydraulic interface 5, in described hydraulic jack 6, be provided with piston and piston rod 14, described air filter 15 is located at control valve 16 sides, and be provided with air inlet, described piston sleeve 9 becomes to be slidably connected with piston, the broken shovel 17 of the interior location and installation of described spade positioning sleeve 10, its port of export is provided with snap ring 11.Hydraulic jack 6 inwall one sides are provided with drainback passage 7, and described drainback passage 7 is communicated with control valve 16, and the opposite side of hydraulic jack 6 inwalls is provided with air duct 4.In described box type accumulator 2, be filled with high pressure nitrogen.Snap ring 11 outsides of spade positioning sleeve 10 ports of export are provided with snap ring button 12, are pulled after lower and can make broken shovel 17 location, and have and prevent broken shovel 17 functions of deviating from.Described broken shovel 17 stretches into behind the interior location of spade positioning sleeve 10, and its upper end contacts with piston and piston rod 14 lower ends.
Hydraulic crushing is shoveled to structure below and using method is described in detail: hydraulic crushing shovel, its tubular fuselage is linked into an integrated entity by box type accumulator 2, control valve 16, hydraulic jack 6, air chamber 8, piston sleeve 9, spade positioning sleeve 10 6 parts from top to bottom successively.Back and handle 1 connect into " T " font; Also comprise removable broken shovel 17 or broken drill rod.In the box type accumulator 2 at fuselage top, be full of high pressure nitrogen.Control valve 16 sides are provided with high/low pressure hydraulic interface 5, can press tube connector to be connected with hydraulic power station with high/low hydraulic fluid.In hydraulic jack 6, be provided with piston and piston rod 14, hydraulic jack 6 inwalls are also provided with the drainback passage 7 of isolation, and drainback passage 7 is communicated with control valve 16.Air filter 15 sides are provided with air inlet, and piston sleeve 9 becomes to be slidably connected with piston.After the spade of broken shovel 17 puts in the interior installation of positioning sleeve 10, located by the snap ring 11 of the port of export, and fastened by the snap ring button 12 in spade positioning sleeve 10 ports of export outsides, prevent that it from deviating from.When use, start hydraulic power station fragmentation shovel 17 shovel heads are put in to rock fracture, in depression of handle 1, also switch 3 is depressed, control valve 16 is opened, and high pressure liquid force feed, through control valve 15, promotes piston and piston rod 14 and moves downward, piston rod ceaselessly hits spade below, make the shovel head of broken shovel 17 enter crack, crack constantly expands under the extruding of fragmentation shovel 17, makes rock division.Box type accumulator 2 is in the time that piston and piston rod 14 moves downward with broken shovel 17, its volume expansion, by hydraulic oil extruding, hydraulic oil is through the drainback passage 7 of hydraulic jack 6 inwalls, enter control valve 16 and low-pressure hydraulic tube connector is back to hydraulic power station, then recycle.Low-pressure hydraulic oil is from control valve 16 is discharged, and high pressure liquid force feed constantly enters from control valve 16, and box type accumulator 2 is compressed again, gets back to original state.Can discharge in time in order to make a small amount of dust producing when the crushing operation, around piston rod, be provided with air chamber 8, air fills air filter 15 air inlet ports, enter air chamber 8 through air duct 4, then discharge from dust outlet 13, dust is taken out of simultaneously, while changing broken shovel 17 or broken drill rod with antifouling piston sleeve 9., snap ring button 12 is pulled downwards, snap ring 11 is loosened, broken shovel 17 just can be extracted, change again the broken shovel of another bar or broken drill rod and carry out operation, and then snap ring button 12 is upwards cocked, snap ring 11 is closed up, broken shovel 17 or broken drill rod just can not be deviate from.
