Abstract
The utility model discloses a rapid collection device for a fresh tobacco leaf vein sample, which is characterized by comprising two nipper-shaped tweezers, wherein pointed blades are installed at the inner sides of the two tweezers respectively, and the pointed blades stretch up and down via strip-shaped slide grooves formed in the tweezers, and fastening screws; and blade point safe protecting sleeves are arranged at the lower ends of the two tweezers. In an unused state, the blade points can stretch into the protecting sleeves; and during use, the positions of the pointed blades in the slide grooves of the tweezers are adjusted to enable the blade points to stretch out of the protecting sleeves, the tweezers are tightly held to enable the pointed blades at the both ends of each of the tweezers to cling to the both sides of a leaf vein and then gash, so as to realize rapid separation of the leaf vein from a tobacco leaf piece. The rapid collection device for a fresh tobacco leaf vein sample disclosed by the utility model has the characteristics that rapid separation for the leaf vein from a tobacco leaf piece can be realized by utilizing the collection device, thus reducing labour intensity and increasing sampling speed; and non-in-vitro sampling for the tobacco leaf can also be realized.
Description
Technical field
The utility model relates to sampling equipment, specifically a kind of device for quick collecting of fresh tobacco leaf vein sample for the tobacco in field test.
Background technology
Flue-cured tobacco vein weight generally accounts for full leaf and weighs 25% left and right, is support blade, carries moisture, nutrient and organic important channel, is one of important research object of biological tobacco research field.Existing sampling means is first fresh tobacco leaf to be picked, then by scissors, fresh tobacco leaf is cut out and obtained vein, then vein is wrapped and is put into liquid nitrogen and preserve with masking foil.In operating process, the experimenter finds that there is following problem in existing sampling means: sample rate is slower, when especially sampling quantity is larger, consuming time longer, tobacco leaf leaves after the cigarette strain in the hungry metabolism state, violent biochemical reaction will occur in inherent material, as RNA degrades, metabolite changes etc., affect the subsequent experimental result of study.Therefore can design a kind of easy to use, sampling efficiently practical instrument caused relevant industry personnel's concern.
Summary of the invention
The purpose of this utility model has overcome above-mentioned the deficiencies in the prior art and a kind of tobacco leaf of need not plucking of providing just, just can complete the sampling of fresh tobacco leaf vein, quick sampling device simple in structure.
The purpose of this utility model is achieved through the following technical solutions: a kind of device for quick collecting of fresh tobacco leaf vein sample, comprise two tweezer folders that are pincer-like, inboard at two tweezer folders is separately installed with a band sharp knife sheet, and flexible up and down by the bar shaped chute and the trip bolt that are opened on the tweezer folder with the sharp knife sheet.
Lower end at two tweezer folders is provided with the point of a knife safety protection jacket, at non-working condition, but in point of a knife indentation protective jacket.
The both sides angle of described tweezer folder is about 20
., the tweezer folder is about 10cm, wide about 2cm, and material is stainless steel.
During use, adjusting the position in tweezer folder chute with the sharp knife sheet, is that point of a knife stretches out protective jacket, and by the tweezer folder of holding with a firm grip, the blade that tweezer is pressed from both sides to two ends band point is close to the vein both sides, takes advantage of a situation and scratches, and realizes separating fast of vein and tobacco leaf.
Characteristics of the present utility model are: utilize this harvester can realize separating fast of vein and tobacco leaf, not only can reduce labour intensity, and can improve sample rate, can also realize sampling in vitro of tobacco leaf.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram with the sharp knife sheet.
Wherein, 1. the tweezer folder, 2. be with sharp knife sheet, 3. bar shaped chute, 4. trip bolt, 5. blade circular hole, 6. point of a knife safety protection jacket.
Embodiment
The utility model is further described below in conjunction with accompanying drawing: the device for quick collecting of fresh tobacco leaf vein sample of the present utility model, comprise two tweezer folders 1 that are pincer-like, inboard at two tweezer folders is separately installed with a band sharp knife sheet 2, and flexible up and down by the bar shaped chute 3 and the trip bolt 4 that are opened on the tweezer folder with the sharp knife sheet, lower end at two tweezer folders is provided with point of a knife safety protection jacket 6, at non-working condition, but in point of a knife indentation protective jacket.
Concrete use-pattern is: according to requirement of experiment, choose suitable sampling cigarette strain in vega, by trip bolt 4, will be with sharp knife sheet 2 to be adjusted to and expose approximately 0.3 ~ 0.5cm of point of a knife, and fixedly tighten clockwise, then will be with the sharp knife sheet, be close to the vein both sides, a finger-tight blade, another is held tight tweezer folder, take advantage of a situation and scratch, realize separating fast of vein and tobacco leaf, obtain rapidly tobacco leaf vein sample, then vein is wrapped and put into liquid nitrogen and preserve with masking foil.After sampling finishes, after be with sharp knife sheet 2 to dismantle to take off and cleaning up, then will be with sharp knife sheet 2 to recall to point of a knife safety protection jacket 6 by trip bolt 4.
Claims (2)
1. the device for quick collecting of a fresh tobacco leaf vein sample, it is characterized in that: comprise two tweezer folders that are pincer-like, inboard at two tweezer folders is separately installed with a band sharp knife sheet, and flexible up and down by the bar shaped chute and the trip bolt that are opened on the tweezer folder with the sharp knife sheet.
