Description
Technical field
The present invention is applied to manned space flight lunar surface artificial sample technical field, is specifically related to a kind of impact penetration type sampling thief.
Background technology
Obtaining the lunar soil sample with good bedding information is a vital task in China's manned moon landing's engineering of carrying out future.Manually knock the method (impacting penetration type core sample method hereinafter referred to as static state) that thin-walled corer makes it injection menology and can obtain one section of good lunar soil sample of bedding information retentivity, but because in penetration process, lunar soil particle is mutually piled up and extrudes, frictional resistance between particle and corer wall is increased, the lunar soil sample length in corer is caused to be shorter than the degree of depth of corer injection menology, namely core-taking rate cannot reach 100%, the method not only adds the energy required for sampling, and core-taking rate and sampling efficiency not high yet.Therefore, how to overcome the above problems, develop a kind of low in energy consumption, core-taking rate is high, be convenient to the lunar soil sampler of cosmonaut's hand-held is current main task target.
Summary of the invention
In order to technical solution background Problems existing, the object of the present invention is to provide a kind of impact penetration type sampling thief.
The present invention solves the problems of the technologies described above the technical scheme taked to be: impact penetration type sampling thief, servomotor coaxially connects driving gear, driving gear is connected by gear drive with driven gear, driven gear upper surface is coaxially fixedly connected with exciting cam, exciting cam has four projections, impact block is the driven member of exciting cam, four cam bawls are evenly equipped with between the projection of impact block and exciting cam, cam bawl is connected with impact block by axle, spring guidepost is installed on cam protective cover, outside spring guidepost, cover has returning spring, returning spring is placed between spring guidepost and impact block, cam protective cover is installed on gear case and covers, cam protective cover has watch window, gear case is made up of upper cover and lower cover, upper and lower covers composition surface place is located by boss, integral installation is on upper backup pad, guide pin bushing is fixed on lower supporting plate, between guide pin bushing and corer, ball retainer is installed, corer coaxial bolts is fixedly connected on the below of impact block, frame is welded by square steel, it is provided with handle and suspension ring.
The present invention has following beneficial effect: only obtain deep layer sample by percussive action, without the need to gyration, the sample bedding information obtained keeps better, core-taking rate is high, the many kinds of parameters such as frequency of impact, ballistic work can be separated separately and study, decoupling is good, and interface structure is simple, convenient disassembly, more easily changes subjects.

embodiment:
Below in conjunction with accompanying drawing, the invention will be further described:
In structural representation sketch by the impact penetration type sampling thief shown in Fig. 1 composition graphs 2, AC synchronous sampling motor 11 coaxially connects driving gear 18, driving gear 18 is connected by gear drive with driven gear 16, AC synchronous sampling motor 11 is by transmission gear 18, 16 by power transmission to exciting cam 17, driven gear 16 upper surface is coaxially fixedly connected with exciting cam 17, exciting cam 17 has four projections, often rotate and can realize four Secondary Shocks in, impact block 7 is the driven member of exciting cam 17, four cam bawls 6 are evenly equipped with between the projection of impact block 7 and exciting cam 17, cam bawl 6 is connected with impact block 7 by axle, spring guidepost 9 is installed on cam protective cover 8, guide effect is provided with impact block for returning spring 10, outside spring guidepost 9, cover has returning spring 10, returning spring 10 is placed between spring guidepost 9 and impact block 7, change returning spring and can obtain different ballistic works, cam protective cover 8 is installed on gear case upper cover 5, cam protective cover 8 has watch window, can prevent the cam personnel that cause because of fault from injuring, have watch window simultaneously, to observe the working condition of cam at any time, gear case is made up of upper cover 5 and lower cover 4, upper and lower covers composition surface place is located by boss, integral installation is on upper backup pad 12, guide pin bushing 14 is fixed on lower supporting plate 13, for location and the guiding of corer 15, between guide pin bushing 14 and corer 15, ball retainer is installed, be convenient to operate better under high frequency effect, corer 15 coaxial bolts is fixedly connected on the below of impact block 7, frame 1 is welded by square steel, it is provided with handle 2 and suspension ring 3 and is convenient to transport and test.
Start AC synchronous sampling motor 11 driving cam means during work, apply shock load by impact block 7 pairs of corers 15, the Shock stress Wave of generation transmits in corer, can the intergranular riding chain effect of spoiled soil, makes it to become loose.Meanwhile, due to the elliptic motion of corer surface particle, soil particle is made to have the characteristic of upwards unidirectional migration, so effectively core-taking rate can be improved.Interface is simple, and the corer of replaceable different surface morphology, for follow-up study work provides convenience.
