Description
Technical field
The invention belongs to rotary digging field of operation, especially a kind of portable hydraulic transmission rotary drilling device and rotary digging method.
Background technique
Thunder hole typically refers to have certain diameter and depth, the circular pit for mine.At this stage, my army is artificial
When laying land mine, thunder hole is excavated by individual soldier and uses engineer spade manual work.Although equipment needed for manual work excavates thunder hole is few, group
Knit implementation flexibly, but on hard ground, manual work excavates that thunder hole speed is slow, low efficiency, and the light instruments such as spade, pick excavate thunder
In irregular shape, size inaccuracy, specification disunity are cheated, earth's surface camouflage layer can not be completely retained.
Compared with manual work, mechanical device can preferably solve the above problems.Currently, can be fast on hard ground
The mechanical device that speed excavates circular pit mainly has auger stem pit-picker, core-drilling machine and vehicle-mounted drilling integral type thunder hole to excavate
Three kinds of device.
Auger stem pit-picker usually provides power by vapour (bavin) oil turbine, axially downwardly tunnels under pressure,
Helical blade cuts soil, and the soil of chopping is thrown to cave wall and under frictional force effect along helical blade under the action of the centrifugal force
Ground is risen to, is shed to cave around cheating.Drill bit is promoted after excavating predetermined depth, forms circular pit.Auger rod-type is digged pit
Machine maximum digs pit diameter as 500mm.It is mainly used for nursery stock plantation, pile ditch excavation, is suitable for loess formation, argillic horizon, sand containing cobble
Gravel soil layer, decomposed rock soil layer, frozen soil layer etc..But auger rod-type pit-picker generallys use gasoline engine and provides power, needs volume
Outer device come reduce revolving speed, promoted torsion, equipment volume and quality are larger.The drill bit of auger rod-type pit-picker was tunneling
Soil is shredded and is dished out by Cheng Zhong, auger stem, can not completely be retained earth's surface camouflage layer and centralized collection waste residue, is unfavorable for mine-laying
The camouflage in region.
Core-drilling machine usually provides power by motor, and masonry hollow boring bit is driven to rotate around axial high speed,
Under pressure, hollow boring bit tunnels downwards cutting target material, promotes drill bit after driving to predetermined depth, uses special tool
Tool takes out core out of hole, forms circular pit.Core-drilling machine maximum is digged pit diameter 200mm, and testing of materials coring is mainly used for,
Soil surface etc. is coagulated suitable for hard soil, bituminous pavement, coagulation.But core-drilling machine generallys use motor and provides power, turns
Speed is higher, and torsion is on the weak side.After core-drilling machine driving to predetermined depth, the columnar core bottom of cutting forming is not turned off, and is needed
It manually to be fractureed out of cave hole using specific purpose tool and take out core, the degree of automation is not high, influences operating efficiency.
Vehicle-mounted drilling integral type thunder hole excavating device provides power using gasoline engine, drives drilling integral type cylinder to bore and surrounds axis
To high speed rotation, under pressure, cylinder bores the target material of driving cutting downwards, tunnels to after predetermined depth, cylinder is bored same
Depth rotation, three horizontal cutter tooth transverse cuts cores promote drill bit after cutting off core, core are proposed, form circular pit.Vehicle
It carries drilling integral type thunder hole excavating device maximum to dig pit diameter 300mm, is mainly used for being suitable for the thunder hole under the conditions of hard soil
It excavates.But vehicle-mounted drilling integral type thunder hole excavating device provides power using gasoline engine, needs additional device to reduce and turn
Speed promotes torsion, and equipment volume and quality are larger, and it is portable to cannot achieve individual soldier, and task is completed in fast reserve.
Thunder hole is excavated with the basic demand of following three aspects: first is that action is rapid.Mine-laying operation is military operation, true
Under the premise of guaranteeing the quality, it is necessary to accomplish that action rapidly, otherwise just will affect operation, or even jeopardize operating personnel's life.Second is that shape
Shape rule.The thunder hole shape of rule is to avoid land mine from tilting and be displaced under external force, ensure the quick-fried essential condition of land mine standard.
Third is that size is accurate, uniform specification.There are many type of land mine, and different types of land mine has on apparent size and embedded requirement
Significant difference, the size and specification in thunder hole must match with land mine apparent size and embedded requirement, could reliable arrangement, reliably
Detonation.Fourth is that completely retaining earth's surface camouflage layer and centralized collection waste residue as far as possible, it is therefore an objective to restore landforms after completing mine-laying operation
As former state, it prevents from being identified easily by enemy.
