Abstract
The invention discloses a coring mechanism capable of maintaining original geological bedding information. The coring mechanism capable of maintaining the original geological bedding information is characterized by comprising a coring drill rod (1); the coring drill rod (1) has a hollow structure; the front section of the coring drill rod is provided with a coring drill bit (2); a maintaining core pipe (3) is arranged on the hollow position; a soft bag (4) folded in a corrugated tube shape is arranged between the coring drill rod (1) and the maintaining core pipe (3); the lower end of the soft bag (4) extends to the lower edge of the maintaining core pipe (3), is turned to the inside of the maintaining core pipe (3) and is connected with a soft bag joint (5); the soft bag joint (5) is connected with a shaping hoist point (7) through a pulling rope (6); and the upper end of the soft bag (4) is provided with a sealing zipper (8). The coring mechanism has the advantages of hard deformation, space conservation, low friction force, stability and reliability, is used for drilling and sampling under complex mechanics and space environment of aerospace, and collecting and encapsulating lunar soil under the premise that the bedding information of the lunar soil is not destroyed.
Description
Technical field
The invention belongs to aerospace and explore the field, relate to a kind of device in moonscape probing sample collection, particularly a kind of mechanism that cores that can keep original geology bedding information realizes utilizing the soft bag of two-layer compound internal layer to the lunar soil sample collection.
Background technology
Space flight and aviation is the human natural forward position engineering of exploring, and walking space-ward has become the requisite sign of science and technology power, and each link is all extremely important in space system engineering; In the face of under the condition of the such complex environment of Aero-Space, how to realize utilizing drilling tool to take the moonscape lunar soil, human especially a kind of challenge; After detector system lands; Will the point that land be drilled through the about 2 meters lunar soil sample of the degree of depth the target area in and drill through to hollow coring drill rod innerly, want complete then and take out parcel, encapsulate, this lunar soil sample need be able to reflect the section original appearance of lunar soil; How just can make the constant and transfer of the aspect that keeps sample, encapsulation process the phenomenon of being scattered can not occur; Still need a kind of special tool to solve this problem, this instrument wants be able to withstand the test of complex spatial and mechanical environment, guarantees that it is reliable and stable; And to keep its portability to adapt to the carrying space needs, still need technological innovation to plug a gap.
Summary of the invention
The present invention the invention provides a kind of mechanism that cores that can keep original geology bedding information for the taking-up encapsulation that the inner lunar soil sample of hollow coring drill rod is complete, can drilling carry out synchronously with collecting, and realizes parcel and encapsulation.
Above-mentioned purpose realizes through following technical scheme: a kind of mechanism that cores that can keep original geology bedding information; It is characterized in that comprising coring drill rod, coring drill rod is a hollow structure, and leading portion is provided with coring bit; Hollow position is provided with the holding core pipe; Space between coring drill rod and the holding core pipe is provided with the folding soft bag of corrugated tube shape, and soft bag lower end is extended to and translates into holding core pipe inside in the place, holding core pipe lower edge, is connected with soft bag joint; Soft bag joint is connected with the shaping reel through pull rope, and soft bag upper end is provided with and seals zip.
The space of the present invention between coring drill rod and holding core pipe is provided with the folding soft bag of corrugated tube shape; Not yielding; Save the space, frictional force is little, and is reliable and stable; Be implemented under complicated mechanics of Aero-Space and the space environment and drill through sampling, can under the prerequisite that the bedding information that keeps lunar soil is not destroyed, realize gathering encapsulation.
Description of drawings
Fig. 1 is the cross-sectional view of the embodiment of the invention;
Indicate title among the figure: 1 coring drill rod; 2 coring bits; 3 holding core pipes, 4 soft bags; 5 soft bags of joints; 6 pull ropes; 7 shaping suspension centres; 8 seal zip.
The specific embodiment
The embodiment of the invention is as shown in Figure 1, and this can keep the mechanism that cores of original geology bedding information to comprise coring drill rod 1, and coring drill rod 1 is a hollow structure; Leading portion is provided with coring bit 2; Hollow position is provided with holding core pipe 3, and holding core pipe 3 floats with coring drill rod 1 and is connected, and the space between coring drill rod 1 and the holding core pipe 3 is provided with the folding soft bag 4 of corrugated tube shape; Soft bag 4 lower ends are extended in the place, holding core pipe 3 lower edges translates into holding core pipe 3 inside; Be connected with soft bag joint 5, soft bag joint 5 is connected with shaping suspension centre 7 through pull rope 6, and soft bag 4 upper ends are provided with and seal zip 8; It is following that it drills through step:
Before following the boring; With soft bag 4 be folded into corrugated tube shape and be placed on drilling rod 1 and holding core pipe 3 between the place, inner space; The upper end is provided with seals zip 8; The lower end is extended in the place, holding core pipe 3 lower edges and translates into holding core pipe 3 inside, is connected with soft bag joint 5, and soft bag joint 5 is connected with shaping suspension centre 7 through pull rope 6;
In the following brill, pull rope 6 length are constant, and soft bag joint 5 is motionless; Drilling rod 1 rotates, and holding core pipe 3 does not change, and drilling rod 1 is descending with holding core pipe 3; Soft bag 4 foldable layers soft bag joint 5, pull rope 6 and shaping suspension centre 7 tractive under stretching gradually; In holding core pipe 3 lower edges places, turn over, increase in the increase of inner soft bag 4 spatial accommodations of holding core pipe 3 with the drilling degree of depth, the coring bit 2 corresponding core district lunar soil of getting get in the soft bag 4 of internal layer.
Behind the following brill, seal 8 pairs of soft bags 4 of zip and implement to seal.
Corrugated tube shape is folding to be placed present embodiment because soft bag 4 is; The distortion that can avoid vibration in the probe flight course and cause; And when turning in the soft bag of drilling 4 and the friction between tube wall littler; Easy operating simple in structure, this mechanism is applicable to the drilling collection encapsulation of under the menology space environment, implementing lunar soil.
