A kind of engineering geological investigation hand drill drilling machine
Technical field
The present invention relates to a kind of drilling machine, more particularly to a kind of engineering geological investigation hand drill drilling machine.
Background technology
In recent years, as the fast development of mountain area engineering construction (such as mountainous area highway), prospecting task also gradually increase.
In general, intermountain depression, the common solution in simple stratum have following three kinds:
(1) drilled using common XY-100 types drilling machine.Common XY-100 types drilling machine is by head, diesel engine, base, volume
Raise, the composition such as boring tower, drilling rod, core barrel, casing, water pump, water pumper, mechanical equipment is heavy, and the whole series weigh 1~2 ton, are not easy to
Carry, it is time-consuming and laborious.
(2) common simple exploring equipment is Luoyang Spade, and Luoyang Spade is made of shovel head, weight linear meter and extension bar.Using
When, ground is hit by manually stabbing Luoyang Spade vertically downward, the soil zone of underground can be gone out using shovel head, according to the unearthed knot of band
Structure, color, density and various inclusions analyze the property of shallow underground soil layer.Although equipment is light, easy to operate, but use
Be manually power, drilling is slow, tunnelling footage is smaller, and run into cohesive soil that underground water can be difficult to fetch earth during driving shows
As if in addition, run into loose layer of sand, can not also be taken to ground.
(3) the prospecting of mountain area intermountain depression is carried out using knapsack churn, a whole set of drilling machine and related accessory are loaded into knapsack,
Carry out simply assembling during use, equipment is made of put-put, drilling rod, core barrel and a set of water system.Make
Used time drives drilling rod and core barrel to be rotated by put-put, from water system to hole in carry out water filling.Although the back of the body
Packet mode drilling machine is light, easy to operate, but uses miniature gasoline engine, and driving power is smaller, rate of penetration is slow, equipment price is held high
It is expensive.
The content of the invention
It is an object of the invention to provide one kind is simple in structure, light, easy to operate, tunnelling footage is big, price is low, favourable
In the engineering geological investigation hand drill drilling machine that engineering geological investigation is smoothly carried out.
The purpose of the present invention is realized by following technical measures:A kind of engineering geological investigation hand drill drilling machine, its feature exist
In:It is mainly made of the small generator that head, drilling rod, core barrel and power are more than 3KW, the power output of the head
End is connected with the upper end of drilling rod, and the upper end of the core barrel and the lower end of drilling rod connect, and the small generator is electricity with head
Connect, the hand handle for 2~3 people grip is detachably installed on the head.
The head of the present invention is equipped with hand handle, 2~3 people can be facilitated to operate, and use power as the small-sized of more than 3KW
Power electric generators, generator is small, power is sufficient, improves driving speed and depth.In addition, the configuration of the present invention is simple,
It is light, easy to operate.
As one embodiment of the present invention, it for 220V, power is 3KW's that the small generator, which uses output voltage,
Gasoline engine generator.
As a modification of the present invention, startup is automatically closed when being equipped with the small generator and being used for abnormal electrical power supply
The safety switch of switch, when starting to work, opens starting switch, makes engine fire, and opens safety switch, when stopping work
When making, closed safe switch, and starting switch is closed, generator is stopped working.Safety switch adds the peace of onsite application drilling machine
Quan Xing.
As a further improvement on the present invention, the lower part of the core barrel is provided with the port to fetch earth.Drilling terminates to take out
After core barrel, the soil body can slowly be disclosed from passage port with the less reinforcing rod of diameter.Avoid the big chance of Luoyang Spade shovel head opening
Water meets the situation that layer of sand is difficult to take soil loading, turn avoid the situation that the soil body is difficult to take out in knapsack churn core barrel.
The present invention can also do following improvement, and the engineering geological investigation hand drill drilling machine further includes bearing, the bearing bag
Base, pillar, clamping piece and lifting seat for clamping head are included, the base is made of the bottom plate of pair of parellel so that drilling rod
From ground is stretched between two bottom plates, the pillar is vertically fixed on the rear end of bottom plate, and the clamping piece is arranged on lifting seat, institute
Lifting seat is stated to be sleeved on pillar and can move up and down and position along pillar.When the present invention is crept into rock, it can be erected at
On bearing, drilling rod is controlled to lift by bearing, so as to fulfill the steady drilling in rock.
As one embodiment of the present invention, the lifting seat is mainly made of pedestal, handle, shaft and tooth card, institute
State pedestal to be placed on pillar, the clamping piece is located on pedestal, and the tooth card is the strip blocks that front has tooth, described
Tooth card is vertically fixed on pillar, and one end of the shaft is fixed on handle, and the other end is inserted into the inner through pedestal, described
Pedestal is equipped with the bearing being placed in shaft for the through hole that shaft passes through, and shaft stretches into the end in pedestal and is equipped with gear, described
Gear is meshed with the tooth on tooth card, is rotated by rotational handle band moving gear, gear and tooth card coordinate and make pedestal in pillar
Upper movement, and then drive clamping piece lifting;Set screw is equipped with the back side of the pedestal, the set screw is screwed into pedestal simultaneously
It is pushed against on pillar and positioning seat body.
Engineering geological investigation hand drill drilling machine of the present invention further includes the drill bit of short cylinder shaped, and the drill bit is removably mounted at
To replace different types of drill bit on the lower end of core barrel.Different Strata is suitable for is drilled using the drill bit of unlike material,
Soil layer can use alloy bit, and lithostratigraphy then uses diamond bit.
Compared with prior art, the present invention has following significant effect:
(1) head of the present invention is equipped with handle, 2~3 people can be facilitated to operate, and use power as the small-sized of more than 3KW
Power electric generators, generator is small, power is sufficient, improves driving speed and depth;In addition, the configuration of the present invention is simple,
It is light, easy to operate, and price is low, is conducive to engineering geological investigation and smoothly carries out.
(2) install safety switch additional on generator, ensure that the Electrical Safety in drilling process.
(3) after drilling terminates to take out core barrel, the soil body can slowly be disclosed from passage port with the less reinforcing rod of diameter.
Avoid the big chance water of Luoyang Spade shovel head opening or meet the situation that layer of sand is difficult to take soil loading, turn avoid in knapsack churn core barrel
The situation that the soil body is difficult to take out.
(4) when the present invention is crept into rock, head can be erected on bearing, control drilling rod to lift by bearing, so that
Realize the steady drilling in rock.
