Abstract

The utility model discloses a moon lunar soil drilling hole external core-picking device, belonging to the field of moon loose lunar soil sampling equipment. A screw rod drill of the device is a solid drill, a drill blade is arranged on the circumference at the lower part of the drill, a bearing matched with the drill blade is arranged at the upper part of the drill, and a connecting sleeve is fixedly connected with the bearing; a collector is a hollow sleeve, the inside of the collector is an annular slope, the lower port of the collector is matched and connected with a core-picking nozzle, the upper port of the collector is matched and connected with the connecting sleeve and is sleeved at the periphery of the screw rod drill, and the bottom of the collector is provided with a sand guide opening connected with a cored hose; as the drilling of the drill, loose sand grains are lifted to a certain height and then enter into the collector, and under the actions of gravity and a centrifugal force, the sand grains can flow to the cored hose outside a hole through the sand guide opening of the collector. By using the device, the problem of drilling loose lunar soil on the moon under the condition of unmanned operation is solved creatively, the packaging and transferring of a rock core subjected to core-picking by drilling lunar soil on the moon are finished efficiently and conveniently, and particularly, feasible excellent equipment is provided for the lunar exploration geological research.

Description

Coring device outside the moon lunar soil boring hole

Technical field

Coring device outside the utility model moon lunar soil boring hole belongs to the loose lunar soil sampling equipment of moon field.

Background technology

At present, known moon lunar soil boring and coring device, form by coring bit, core barrel and the core of the card, its coring bit is the hollow drill bit that interior external diameter is arranged, along with the drill bit rotation is down crept into, core enters in it from the drill bit internal diameter, and core barrel is equipped with in drill bit top, and the core that utilizes the core of the card device will enter core barrel then is locked in the core barrel and proposes ground and obtain core.This device is got core and whole core barrel must be proposed outside the hole, and under the operatorless condition of the moon, this causes great difficulty for the encapsulation and the transfer of core.Yan Taining etc. are at " geological science and technology information ", VOL.23, and NO.4, P12-14 is described to add external spiral at frame of the bit and core barrel, promptly belongs to this type of.

The utility model content

The purpose of this utility model provides coring device outside a kind of moon lunar soil boring hole, makes that loose lunar soil enters the cored flexible pipe smoothly in the drilling process, so that the encapsulation of core and transfer under the unattended condition.

The purpose of this utility model is achieved through the following technical solutions: coring device outside this moon lunar soil boring hole, form by screw rod drill bit, adapter sleeve, corer, collector and cored flexible pipe, the screw rod drill bit is a solid bit, the lower circumference face is a bit blades, top stepped shaft bearing is connected with bearing, and adapter sleeve is connected with bearing fixing; Collector is a hollow sleeve, and inside is the annular space inclined-plane, and its lower port and corer mouth are connected, and its upper port and adapter sleeve are connected and are sleeved on screw rod drill bit periphery, and the collector bottom is provided with leads the sand mouth, leads the sand mouth and is connected with the cored flexible pipe.

The gradient on the inner annular space of collector inclined-plane is 30 °～60 °, and the height on collector annular space inclined-plane is lower than the height of bit blades section.

The utility model device is at the concrete situation of the very dry loose lunar soil of the moon and design, form by screw rod drill bit, adapter sleeve, corer, collector and cored flexible pipe, according to the utility model, when the drill bit rotary drilling, only the screw rod drill bit rotates alone, and corer and collector only move forward and do not rotate, rotary drilling along with drill bit, loose sand grains rises to certain height and enters collector, sand grains is under gravity and action of centrifugal force, by leading in can the ostium outer cored flexible pipe of sand mouth of collector.The utility model device, creativeness has solved under unattended condition, drill through the difficult problem of the loose lunar soil of the moon, finish the core encapsulation and the transfer of moon lunar soil boring and coring efficiently, easily, be in particular the lunar exploration geological research practicable good equipment is provided.

Embodiment

Below in conjunction with accompanying drawing, further specify the utility model and how to implement.

Coring device outside the utility model moon lunar soil boring hole, form by screw rod drill bit 5, adapter sleeve 2, corer 7, collector 4 and cored flexible pipe 6, screw rod drill bit 5 tops are equipped with motor 5-3, among the stepped shaft bearing 5-2 of top two bearings 1 are housed, be provided with bearing cap 3 in the lower end of two bearings 1, adapter sleeve 2 is fixedlyed connected with bearing 1, and screw rod drill bit 5 lower circumference faces are bit blades 5-1; Collector 4 is a hollow sleeve, the mouth of pipe of its lower port 4-X and corer 7 is connected, engage sleeves is contained in screw rod drill bit 5 peripheries by being threaded for its upper port 4-S and adapter sleeve 2, and collector 4 bottoms are provided with leads sand mouth 4-1, cored flexible pipe 6 with lead sand mouth 4-1 and fixedly connected.

Collector 4 inner hollow are annular space inclined-plane 4-2, and this annular space inclined-plane gradient is 30 °～60 °, and this annular space inclined-plane 4-2 highly is lower than height of bit blades 5-1 section.

When adopting the utility model device to drill through the moon lunar soil core, screw rod drill bit 5 is under given rotating speed during rotary drilling, screw rod drill bit 5 moves down under the certain pressure effect, core moves up along screw rod drill bit 5-1 blade inclined-plane, when the drill bit rotary drilling, only the screw rod drill bit rotates alone, and 4 reaches of corer 6 and collector, do not rotate, the space is formed on the drill bit bottom, the sand grains loose when core rises to certain altitude along screw rod blade 5-1 inclined-plane, and core enters collector 4 under gravity and centrifugal action, enters in the cored flexible pipe 6 outside the hole by leading sand mouth 4-1 thereupon, creeping into core continuously constantly enters in the cored flexible pipe 6 outside the hole, creep into certain projected depth up to drill bit, thereby get core outside the satisfactory realization hole, make things convenient for the encapsulation and the transfer of core.

The utility model device adopts the high abrasion resisting material manufacturing.
