Abstract

Disclosed is an underground excavator capable of punching deep holes to underground. A barrel is installed on a barrel cover of a combustor. The principle of a soil extending pipe being sleeved on the barrel cover of the combustor is that the soil extending pipe is not driven by the impacting of the barrel cover of the combustor. An oil pump sliding steel ball is installed at the bottom lower corner of the barrel, and when a piston falls down, an oil pump plunger arranged on the piston is driven in a pressed mode to enable fuel oil to be sprayed to the barrel cover of the combustor through a fuel spray nozzle to explode, and then the barrel cover of the combustor impacts downwards to punch holes, and the piston impacts upwards to hit against springs installed at the upper portion of the barrel to perform reciprocating motion. The underground excavator is especially suitable for the use of punching holes to underground when a foundation is laid in construction industry, grouting mortar and reinforcing the foundation.

Description

Underground perforator

Affiliated technical field

The utility model relates to the underground perforator of beating dark hole below ground, burrows to underground when especially being applicable under the building trade basis, and the pouring mortar, firmly ground uses.

Background technology

At present, the existing building industry is weight body and function engine to be risen to the high-altitude then decontrol to the underground equipment that burrows, and is fallen to clashing into by the deadweight of weight body to burrow on the ground.Its disadvantage is that weight body cost is high, needs for a long time when promoting to the high-altitude, also wastes especially power.

Summary of the invention

For overcome existing high to the underground equipment manufacturing cost that burrows, consumption of power is large, inefficient disadvantage, the utility model provides a kind of underground perforator, this underground perforator adopts the strength of fuel detonation that the cylinder cap head is burrowed to underground impact, and particularly impact velocity is fast, and the effect that burrows is high.

The technical scheme that its technical problem that solves the utility model adopts is: on the cylinder cap of combustion chamber, supportting native pipe box, to be contained in principle on the cylinder cap of combustion chamber be that the combustion chamber cylinder cap does not drive support soil pipe when impacting with the cylinder barrel.Oil pump slip steel ball device is at the beneath angle of cylinder bucket, the fuel feed pump plunger that installs on piston when piston falls pushes fuel oil is ejected in the cylinder cap of combustion chamber by atomizer and fires, the combustion chamber cylinder cap impacted downwards burrowing, piston is made progress shock in the work that moves back and forth of the spring of cylinder bucket upper unit.The oil transportation duct ligation is solid on oil pump, and wire rope knot is solid to be used when when piston is used for opening the fuel outburst piston being pulled to high point.

The beneficial effects of the utility model are, the strength that has realized adopting the fuel oil outburst is beaten dark hole to underground, particularly impact shuttle speed fast, and the effect that burrows is high, and job costs have been saved much than the existing underground equipment of burrowing.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the vertical planar configuration figure of side of the present utility model.

1. petroleum pipelines among the figure, 2. piston, 3. oil pump, 4. oil pump slip steel ball, 5. atomizer, 6. combustion chamber cylinder cap, 7. support soil pipe, 8. wire rope, 9. spring, 10. cylinder bucket.

The specific embodiment

In Fig. 1, on combustion chamber cylinder cap (6), it is that combustion chamber cylinder cap (6) does not drive support soil pipe (7) when impacting that support soil pipe (7) is sleeved on principle on the combustion chamber cylinder cap (6) with cylinder bucket (10) device.Oil pump slip steel ball (4) device is at the beneath angle of cylinder bucket (10), when piston (2) falls, the fuel feed pump plunger of the upper device of piston (2) pushed fuel oil is ejected in the combustion chamber cylinder cap (6) by atomizer (5) and fire, combustion chamber cylinder cap (6) impacted downwards burrowing, with piston (2) upwards shock in the work that moves back and forth of the spring (9) of cylinder bucket (10) upper unit.Petroleum pipeline (1) knot is solid on oil pump (3), and wire rope (8) knot is solid to be used piston (2) when piston (2) is used for opening the fuel outburst when pulling to lofty perch.

Claims

1. underground perforator, it is characterized in that the cylinder barrel on the cylinder cap of combustion chamber, supportting native pipe box is contained on the cylinder cap of combustion chamber, oil pump slip steel ball device is at the beneath angle of cylinder bucket, the fuel feed pump plunger that installs on piston when piston falls pushes fuel oil is ejected in the cylinder cap of combustion chamber by atomizer and fires, and the combustion chamber cylinder cap is impacted burrowing downwards, and piston is made progress shock on the spring of cylinder bucket upper unit, the oil transportation duct ligation is solid on oil pump, and wire rope knot is solid on piston.
