Problems solved by technology

[0004] 1) Since the walnut green peel test requires a small amount of green peel samples, the walnut green peel is peeled off from the walnut, chopped and then selected for green peel samples, and the sampling efficiency is low;
[0005] 2) Chopped walnut green skins are of different sizes and irregular shapes. It takes a long time to select a sample of appropriate size green skins, and the chopped walnut green skins are prone to browning after being in contact with air for a long time. the accuracy of the

Embodiment 1

[0032] An experimental sampler, such as figure 1 , figure 2 As shown, it includes a cylindrical shell 1 with a hollow interior, the front end of the cylindrical shell 1 is provided with a sampling tube 2 communicating with the inside of the cylindrical shell 1, and the end of the cylindrical shell 1 is provided with a guide hole 13 coaxial with the sampling tube 2 , the guide hole 13 is inserted with a push-pull rod 3, the push-pull rod 3 is slidably matched with the guide hole 13 and the end is exposed to the guide hole 13; Adapted to the sampling tube 2, the push-pull rod 3 is provided with an annular flange 31, and the annular flange 31 is in sliding contact with the inner wall of the cylindrical housing 1; when the annular flange 31 is against the end inner wall of the cylindrical housing 1 , the front end of the ejector rod 4 is inserted into the sampling tube 2, when the front end of the push-pull rod 3 is against the inner wall of the front end of the cylindrical hous...

Embodiment 2

[0045] In order to clearly show the differences and connections between this embodiment and Embodiment 1, the same functional components in the figure are indicated by the same symbols.

[0046] The features of this embodiment that are the same as those of Embodiment 1 will not be described in detail. The features of this embodiment that are different from Embodiment 1 are:

[0047] Such as image 3 , Figure 4 As shown, the sampling tube 2 in this embodiment is a hexagonal prism tube, the diameter of the circumscribed circle of the hexagonal prism tube is 4mm, the diameter of the circumscribed circle of the hexagonal prism tube includes but is not limited to 4mm, and can also be Any value within the range of 7 mm does not affect the protection scope of the present invention.

[0048] The wall thickness of the sampling tube 2 in this embodiment is 0.5 mm, which can cut the sampling tube 2 into the walnut green husk quickly while ensuring that the sampling tube 2 has a certain ...

Embodiment 3

[0051] In order to clearly show the differences and connections between this embodiment and Embodiment 1, the same functional components in the figure are indicated by the same symbols.

[0052] The features of this embodiment that are the same as those of Embodiment 1 will not be described in detail. The features of this embodiment that are different from Embodiment 1 are:

[0053] Such as Figure 5 , Figure 6 As shown, the sampling tube 2 in this embodiment is a cylindrical tube, the inner diameter of the cylindrical tube is 4mm, the inner diameter of the cylindrical tube includes but is not limited to 4mm, and can also be any value in the range of 3-5mm, without affecting Protection scope of the present invention; adopting 4mm in the present embodiment is the preferred scheme that the applicant sums up after repeated random sampling, specifically, the walnut green peel sample required for the walnut green peel enzyme activity experiment is the walnut green peel of quality...

Abstract

The invention discloses a sampler for experiments, which comprises a columnar shell with a hollow interior, wherein a sampling tube communicating with the interior of the columnar shell is arranged atthe front end of the columnar shell; the tail end of the columnar shell is provided with a guide hole coaxial with the sampling tube, a push-pull rod is inserted in the guide hole, the push-pull rodis in sliding fit with the guide hole, and the tail end of the push-pull rod is exposed out of the guide hole; the front end of the push-pull rod is connected with an ejector rod with the same lengthas the sampling tube, an annular flange is arranged on the push-pull rod, and the annular flange is in sliding contact with the inner wall of the columnar shell; when the annular flange is propped against the inner wall of the tail end of the columnar shell, the front end of the ejector rod is inserted into the sampling tube, and when the front end of the push-pull rod is propped against the innerwall of the front end of the columnar shell, the ejector rod is completely inserted into the sampling tube. The sampler of the invention has the beneficial effects that: when the sampler is used forsampling walnut green husks, experimenters do not need to peel the walnut green husks from walnuts or cut the walnut green husks, the operation is convenient and labor-saving, a sampling efficiency ishigh, and the accuracy of experimental results is improved.

Description

technical field [0001] The invention relates to the technical field of sampling equipment, in particular to an experimental sampler. Background technique [0002] Fresh walnuts have the characteristics of fresh and tender taste, less damage to nutrients, and higher health care functions. They are loved by consumers and have a good market prospect. Storage with green skin can effectively prolong the storage period of fresh walnuts, so a series of physiological activities of green skin directly affect the freshness period of fresh walnuts. [0003] When carrying out the physiological and biochemical experiments of walnut green peel, it is necessary to sample walnut green peel; the sampling method of walnut green peel commonly used at present is: first peel off walnut green peel from walnut, then chop the peeled walnut green peel, select the size Suitable walnut green peel is carried out experiment, although said method has realized the sampling of walnut green peel, still the...
