The specific embodiment
Referring to shown in Figure 1, the portable impact tamping pickaxe of internal combustion of the present utility model comprises internal combustion engine 1, deceleration crankcase 2, impacts cylinder 3, driven plunger 5, impact piston 6, impacting pickaxe clamping cylinder 8, tamping pickaxe 9 and is fixedly arranged in handle 33 on the tamping pickaxe outer wall;
As shown in Figure 2, driving gear 21 in the deceleration crankcase 2 is by centrifugal clutch 11, link to each other with internal combustion engine 1 output shaft, crank gear 22 in the deceleration crankcase 2 is provided with crank-link mechanism, connecting rod 4 lower ends in the crank-link mechanism are connected with driven plunger 5, impact cylinder 3 usefulness bolts and be fixed in deceleration crankcase 2 belows, driven plunger 5 is suspended in impacts in the cylinder 3; Driven plunger 5 pumps in the cylinder sleeve 32 that impacts cylinder 3;
Shown in Fig. 3 and 6, impacting cylinder 3 outer walls is cylinder body 31, and the inboard is equipped with cylinder sleeve 32; Cylinder body 31 is provided with vertical connectivity slot 311, cylinder sleeve 32 middle parts offer three row's air vents 321, the lower end offers row's oil mist holes 322, air vent 321 and oil mist holes 322 all are connected with vertical connectivity slot 311, impact cylinder 3 bottoms and be fixed with an impact piston fairlead 7, have the pore that is connected with oil mist holes 322 on the fairlead, the pore outer cover is provided with " O " type ring, forms a unidirectional pore; Vertical connectivity slot 311 lower ends are provided with oil storage tank 312, and the outside of oil storage tank 312 is provided with oil filler 313, is filled with a certain amount of lubrication oil in the oil storage tank 312; Vertical connectivity slot 311 communicates with deceleration crankcase 2;
As shown in Figure 5, the lower end of impacting cylinder 3 is connected with impacting pickaxe clamping cylinder 8 with bolt, impacting pickaxe clamping cylinder 8 upper inner are equipped with spring protecting sleeve 81, spring protecting sleeve 81 can move up and down, between spring protecting sleeve 81 and impact piston fairlead 7, be provided with spring, impact piston 6 places and impacts cylinder 3, and the piston rod of impact piston 6 passes fairlead 7 and stretches into downwards in the spring in the spring protecting sleeve 81; Impacting pickaxe clamping cylinder 8 bottoms are provided with pick cover 91, are inserted with tamping pickaxe 9 in the pick cover 91, and the arranged outside of pick cover 91 has the spacing card 92 of tamping pickaxe; Driven plunger 5 and impact piston 6 all can pump in cylinder sleeve;
As shown in Figure 4, be provided with damper impacting the cylinder block outside: form by two guide pillars 332, four holders 331, sliding sleeve 333, spring 334 and damping cushion rubbers 335; The two ends up and down of impacting cylinder 3 both sides external are respectively arranged with holder 331, holder 331 is by being bolted on the cylinder body 31 that impacts cylinder 3, placed guide pillar 332 in the holder 331, guide pillar 332 outer upper are arranged with sliding sleeve 333, the bottom is arranged with damping spring 334, spring 334 is enclosed within and places on the guide pillar 332 between sliding sleeve 333 and the lower fixed seat 331,331 of guide pillar 332 and holders are provided with yielding rubber circle 335, and handle 33 is fixed on the sliding sleeve 333.
Operating principle is as follows:
When pressing down handle 33, tamping pickaxe 9 upwards pushes away pick cover 91 by the shoulder of its upper end, pick cover 91 upwards pushes away spring protecting sleeve 81 by the boss in spring protecting sleeve 81, spring protecting sleeve 81 compression springs are moved up with tamping pickaxe, so just make the tamping pickaxe upper end promote the displacement that impact piston 6 upwards produces an ormal weight, this displacement makes the upper end of impact piston 6 upwards cross two rows that arrange in the air vents 321 at impact cylinder sleeve 32 middle parts three, therefore, when driven plunger 5 is upwards moved, rely on the vacuum sorption impact piston 6 that produces to move up together, when driven plunger 5 moves down, by air cushion impact piston 6 is impacted downwards, finish the one-shot task, so circulation produces the continuity impact.
When lifting handle 33, opposite with said process, under the effect of spring 334, tamping pickaxe 9 produces a downward displacement, when impact piston 6 moves downward, make impact piston 6 upper ends cross three row's air vents 321 at cylinder sleeve middle part downwards, make between driven plunger 5 and the impact piston 6 and lose due vacuum, just can not pick up impact piston 6 when driven plunger 5 moves up, stop to impact.That is to say, impacting pickaxe work when handle presses down, impacting pickaxe was not worked when handle lifted.
When tamping pickaxe is worked, because driven plunger 5 and impact piston 6 high speed in cylinder moves back and forth, generation high speed rough air between cylinder 3 and the deceleration crankcase 2 will impacted, the unidirectional pore at the air communication overbump piston guide cover middle part of impact piston cavity of resorption sprays in lubrication oil, make oil atomization, and under the air-flow effect, form mist of oil, impact cylinder 3 and deceleration crankcase 2 running gears are lubricated, the pore outside at impact piston fairlead 7 middle parts is with rubber " O " type ring, form unidirectional pore, so the air-flow that impacts in the cylinder cavity of resorption can only spray in lubrication oil, form mist of oil, impact cylinder and lubrication oil can not be sucked.Overlap 91 lower ends pick and be provided with spacing card 92, to prevent tamping pickaxe 9 landings.
