Description
Technical field
The present invention relates to a kind of laboratory apparatus, more particularly to a kind of use for laboratory frozen fish sampler.
Background technology
During the inspection and quarantine of aquatic products, many aquatic products are freezen protectives, in micro- life to cooling aquatic products
During analyte detection, if carrying out defrosting sampling, the requirement that national standard is directed to microorganism detection is not met；Therefore according to detection
It is required that be directly sampled under freezing environment, to ensure the reliability of testing result.The aquatic products hardness of freezing is big, passes
System is using tweezers hand sample is seen, and time-consuming and laborious, sampling difficulty is big.
Invention content
During solving frozen fish microorganism detection, sampling difficulty is big, time-consuming and laborious
Problem provides a kind of use for laboratory frozen fish sampler.
The technical solution adopted by the present invention to solve the technical problems is：A kind of use for laboratory frozen fish sampling dress
It sets, including hand-held part, sampler barrel, flexible electric cylinders, sampler barrel is cylindric, rear end is rotatably plugged in hand-held part, front end face is set
There is cutter head, motor is equipped in the hand-held part, motor is using planetary gear mechanism connection sampler barrel and flexible electric cylinders, motor
The sun gear of axis connection planetary gear mechanism is exported as input, the planet carrier connection of planetary gear mechanism stretches electric cylinders as row
Carrier exports, and the gear ring connection sampler barrel of planetary gear mechanism is exported as gear ring, and gear ring passes through positive rotatable, reversed locked
Ratchet connect hand-held part, flexible electric cylinders include cylinder body and piston, and when motor forward direction exports, ratchet forward direction is rotatably exported, stretched
The piston of contracting electric cylinders inside contracts, and when motor reversely exports, ratchet is locked, and the piston for electric cylinders of stretching stretches out.The present apparatus is driven using motor
Dynamic cutting frozen fish, instead of sampling manually, be simple, convenient and fast.When motor forward direction exports, planet carrier and gear ring are defeated simultaneously
Go out, when planet carrier drives the piston for electric cylinders of stretching to inside contract on earth, planet carrier is locked to be no longer rotated, and gear ring drives sampler barrel to turn at this time
Dynamic, cutting sampling makes the frozen fish cut be maintained in sampler barrel.When having enough samples in sampler barrel or aquatic products
When product have been sampled cylinder and penetrate, motor reversely exports, and ratchet locks gear ring, and sampler barrel can not rotate backward, only planet carrier
It rotates backward, drives the piston for electric cylinders of stretching protruding, sample is released.When sampling again, it can repeat the above process.Often
After the completion of primary sample, sampler barrel can be cleaned.
Preferably, being connected using bushing between the sampler barrel and gear ring, bushing engages gear ring, and sampler barrel and tooth set are adopted
It is detachably connected with screw thread.Sampler barrel can be with disassembly, cleaning.
Preferably, the front end inner tube wall of the sampler barrel is equipped with the spiral lamination of convex.Spiral lamination can be in sampler barrel
Certain guiding is formed when cutting sampling；When sampler barrel is extracted, spiral lamination can play the role of fastener sample, keep away
Exempt from sample landing；Simultaneously as sampler barrel sampling process high speed rotates, high temperature certainly will be generated at the sample of cutting position,
Therefore, when the piston of flexible electric cylinders releases sample, spiral lamination can play the role of scraper, will take out sample close to barrel
Outer layer strike off, removal receive cutting heating surface layer sample, be take out sample it is representative.
Preferably, the barrel of the sampler barrel road spiral lamination rear end offers cleaning hole, cleaning hole is uniformly opened along barrel
If several.
Preferably, when the flexible electric cylinders are inside contracted on earth, piston nose position is no more than the position of spiral lamination rearmost end.
Preferably, the flexible electric cylinders piston external diameter is no more than the internal diameter of spiral lamination.
The present invention uses the cooperation of planetary gear combination ratchet, completes the one-directional rotation cutting sampling of sampler barrel and stretches
Electric cylinders will take out the action of sample release, facilitate sampling of the laboratory to frozen fish, improve sampling efficiency.

Specific implementation mode
Below by specific embodiment and in conjunction with attached drawing, the present invention is further described.
Embodiment：A kind of use for laboratory frozen fish sampler, as shown in Figure 1.The present apparatus includes hand-held part 1, takes
Sample cylinder 11, flexible electric cylinders 8.Sampler barrel is cylindrical shape, and front end face is sampling end, is equipped with cutter head 14, and rear end is threaded with
Bushing 10,10 rear end of bushing are rotatably connected with hand-held part, and the inner wall of sampler barrel front end is equipped with inwardly protruded helix 13, spiral shell
4 cleaning holes 12 are uniformly opened up on the barrel at 13 rear of spin line.The inside of bushing is fixedly installed flexible electric cylinders 8, electric cylinders of stretching 8
Front end is telescopic piston 9, and the outer diameter of piston 9 is less than the internal diameter of sampler barrel convex helix.When piston inside contracts, piston nose
Face is located on rear side of the cleaning hole of sampler barrel.
Be equipped with motor 2 in hand-held part 1, motor 2 using 11 rear end of planetary gear mechanism connection sampler barrel bushing 10 and
Flexible electric cylinders 8, motor output shaft connect the sun gear 2 of planetary gear mechanism as input, and planetary gear mechanism planetary gear 4 drives
Planet carrier rotates, and the connection of planet carrier 6 stretches electric cylinders as planet carrier output, and the gear ring 5 of planetary gear mechanism passes through middle rotating disk
Axis 16 connects sampler barrel and is exported as gear ring, and gear ring 5 connects hand-held part by positive rotatable, reversely locked ratchet 7, stretches
Electric cylinders 8 include cylinder body and piston 9, and cylinder body is fixed with hand-held part, and when motor forward direction exports, ratchet is positive rotatably to be exported, is flexible
The piston of electric cylinders inside contracts, and when motor reversely exports, ratchet is locked, and the piston for electric cylinders of stretching stretches out.The axis of transfer gear shaft 16
Position is fixed, both ends respectively with gear ring, bushing engaged transmission.Transfer gear shaft 16 be uniformly arranged on ring week it is multiple, with keep
Equalising torque.Using transfer gear shaft, it is circumgyration part, the problem that can not be fixed entirely to avoid the cylinder body periphery of flexible electric cylinders.
The present apparatus is using motor driving cutting frozen fish, instead of sampling manually, be simple, convenient and fast.Motor forward direction is defeated
When going out, planet carrier and gear ring export simultaneously, and when planet carrier drives the piston for electric cylinders of stretching to inside contract on earth, planet carrier is locked no longer to be turned
