Abstract

The invention discloses an electric sampler of a DNA detection sample. The electric sampler comprises a sampler housing and cutting heads arranged on a lower end surface of the sampler housing. The cutting heads are uniformly distributed along a peripheral direction of the lower end surface of the sampler housing. The electric sampler is characterized in that the sampler housing has a hopper shape; the center of the sampler housing is provided with a drill; an upper end of the sampler housing is provided with an end cover; a drill rod of the drill is rotatingly connected to the end cover by a bearing; the drill rod in a tapered part of the sampler housing is provided with a stirring cutter; a part of the drill rod stretching out of the end cover is connected to an electric drill hander; and a cutting part of the drill is arranged in the sampler housing and stretches to a lower end of the sampler housing. The electric sampler has a simple structure, is convenient for operation, realizes continuous sampling in a closed space, realizes sample mixing dissolution in the same closed space after sampling, reduces the influence produced by the environment on the sample, and guarantees accuracy of meat sample detection.

Description

The electronic sampler of a kind of DNA detection sample

Technical field

The present invention relates to a kind of sampler, relate in particular to the electronic sampler of a kind of DNA detection sample.

Background technology

The sampling that at present meat sample DNA detects, generally adopts manual tool to carry out stripping and slicing sampling, or with the cork drill sampling of punching.When sampling, on a sample, sample from several differences, if adopt manual tool sampling, excision meat sample that be repeatedly tissue around, repeatedly samples, and the sample of obtaining carries out after combination treatment, then carries out further work; If with punch tool sampling, often get once and all eject with top rod, detect get again mixed sample after the sample mix of taking out at every turn.Although these two kinds of sampling methods are simple to operate, efficiency is slower, while pipetting sample, easily because the contact of external environment and article causes secondary pollution, causes error to the accuracy that detects sample.In order to address these problems, need a kind of sampler badly, this sampler can complete in the space of a sealing sample is run continuous samples, and in same enclosed space, completes the miscible of sample after sampling, reduces the impact of external environment on sample.

Summary of the invention

For the above-mentioned problems in the prior art, the invention provides the electronic sampler of a kind of DNA detection sample, it can complete in the space of a sealing sample is run continuous samples, and after sampling, in same enclosed space, complete the miscible of sample, reduce the impact of external environment on sample, guaranteed the accuracy of meat sample detection.

The present invention is achieved by the following technical solution: the electronic sampler of a kind of DNA detection sample, comprise sampler housing and be arranged on the cutter head of sampler housing lower surface, described cutter head is uniformly distributed along the circumferential direction of its sampler housing lower surface, it is characterized in that, described sampler housing is funnel-form, the center of funnelform sampler housing arranges drill bit, its upper end arranges end cap, the drilling rod of described drill bit is connected by bearing is rotating with end cap, described be arranged at inside, sampler housing taper position drilling rod be provided with stirring blade, the drilling rod part of stretching out outside end cap is connected with the electric drill chuck of electric drill, the drilling part of described drill bit is arranged in sampler housing, and extend to sampler housing lower end.

For the convenient sampler that extracts, on sampler housing, be provided with handle, described handle is across being arranged on sampler housing.

As preferably, on described end cap, be symmetrical arranged four and connect otic placode, on described sampler housing, be provided with four connection tongues corresponding to connecting otic placode.By realizing being connected of end cap and sampler housing by connecting otic placode with being connected tongue fastening, this syndeton is convenient to being connected and dismounting of end cap and sampler housing.

The invention has the beneficial effects as follows: the electronic sampler of a kind of DNA detection sample of the present invention, it is not only simple in structure, easy to operate, and can in the space of a sealing, realize the serial sampling to a sample, and after sampling, in same enclosed space, complete the miscible of sample, reduce the impact of external environment on sample, guaranteed the accuracy of meat sample detection.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the invention will be further described:

Fig. 1 is structural representation of the present invention;

Fig. 2 is the sectional view of end cap;

In figure: 1-sampler housing, 2-cutter head, 3-connect otic placode, 4-connects tongue, 5-end cap, 6-drill bit, 61-drilling rod, 62-drilling part, 7-stirring blade, 8-electric drill, 9-handle.

Embodiment

As shown in Figure 1 and Figure 2, the present invention includes sampler housing 1 and be arranged on the cutter head 2 on sampler housing 1 lower surface, cutter head 2 is uniformly distributed along the circumferential direction of its sampler housing 1 lower surface, and described sampler housing 1 is funnel-form, and the center of funnelform sampler housing 1 arranges drill bit 6.The upper end of described sampler housing 1 connects end cap 5 by connection otic placode 3, connection tongue 4, and the number of described connection otic placode 3 is four and is symmetricly set on end cap 5, on described sampler housing 1, is provided with four connection tongues 4 corresponding to connecting otic placode 3.The drilling rod 61 of described drill bit 6 is connected by bearing is rotating with end cap 5, described be arranged at sampler housing 1 inside, taper position drilling rod 61 be provided with stirring blade 7, stirring blade 7 is symmetrical arranged with respect to drilling rod 61, drilling rod 61 parts of stretching out outside end cap 5 are connected with the electric drill chuck of electric drill 8, the drilling part 62 of described drill bit 8 is arranged in sampler housing 1, and extends to sampler housing lower end.On sampler housing 1, be provided with handle 9, described handle 9 is across being arranged on sampler housing 1.

Use time of the present invention, first by the end cap that drill bit is housed by be fastened and connected plate be connected tongue and sampler housing links together, then the drilling rod part being arranged on outside sampler housing is connected on the electric drill chuck of electric drill.Mention sampler by handle, the cutter head of sampler housing lower end is aimed to sampling spot, open the switch on electric drill, drill bit starts rotation, down promotes sampler with hand by handle, and under the acting in conjunction of drill bit and hand, meat sample is by the drilling sample device of keeping forging ahead.A sampling spot is collected after meat sample, mention sampler and start again another sampling spot sampling, the meat sample of the different sampling spots of obtaining in sampler, in sampling, mixed by the stirring blade rotating with drill bit simultaneously, after continuous like this five sub-samplings, for meat sample is fully mixed, the drill bit of sampler also needs to rotate for a moment again.After meat sample mixes, the electric drill chuck of electric drill is separated with drilling rod, pull down the end cap with drill bit and stirring blade, go out the meat sample mixing in sampler housing with regard to usable samples bale-out, carry out next step testing.

Except the technical characterictic described in above-mentioned specification sheets, be the known technology of those skilled in the art.
