Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of sampling equipment for inner packaging of fine chemical products, in particular to a sampling device for detachable and washable inner packaging and graded quantitative sampling. Background Art
[0002] At present, in the fields of biology, pharmaceuticals, new materials, etc., it is necessary to frequently sample raw materials, etc., and existing sampling tools of different specifications are widely used due to their own performance, such as the commonly used long-handled sampling spoon, open-type sampling file, rotary sampler, etc. However, some problems are also exposed in the sampling process, such as: the long-handled sampling spoon can only collect samples of limited depth on the surface of the material; the open-type sampling file inserted into the material is easy to cause the mutual flow of materials at different depths; the rotary sampler cannot quantitatively and accurately sample materials with poor fluidity and there is a risk of contamination in the cleaning dead corner. Therefore, the existing sampling equipment can no longer meet the needs. Utility Model Content
[0003] The purpose of the utility model is to improve the deficiencies of the prior art and provide a sampling device for detachable and washable inner packaging for graded quantitative sampling, which is quantifiable, multi-purpose, easy to operate, low-cost, reliable and durable.
[0004] The purpose of the utility model is achieved in this way. A sampling device for graded quantitative sampling with detachable and washable inner packaging includes an outer shell, and its characteristics are that the outer shell is hollow cylindrical and has an opening at the tail, the head of the outer shell is provided with a pointed material breaking cone, the tail is provided with an outer shell rotating handle, a strip sampling window is provided on the outer shell along its axial direction, and a sampling rod is also provided, the sampling rod is movably inserted in the hollow outer shell, the sampling rod is provided with slots at intervals, the hollow sampling capsule with a feed window is movably mounted in the slots, the total length of all the slots is less than or equal to the length of the sampling window, and the tail end of the sampling rod is provided with a sampling rod rotating handle.
[0005] To further achieve the purpose of the utility model, a sampling scraper arranged along the axial direction of the shell may be provided on the shell at the upper edge or the lower edge of the sampling window.
[0006] To further achieve the purpose of the utility model, a hierarchical scale may be provided on the housing, and a slot scale may be provided on the sampling rod, and the scales of the two scales may correspond.
[0007] To further achieve the purpose of the present invention, the width of the sampling window may be smaller than the diameter of the sampling rod.
[0008] Compared with the prior art, the utility model has the following significant features and positive effects: the utility model includes a sampler shell, a plurality of sampling capsules and a sampling rod with a slot. The sampler shell is a hollow sleeve. The pointed material-breaking cone at the front end of the sleeve is convenient for inserting into the material. The main body of the shell is provided with a hollow material collection window. The hollow cylindrical sampling capsule has a feeding window. The sampling capsule can be embedded and mounted in the corresponding slot on the sampling rod, and can be rotated 180 degrees around the axis of the slot to achieve the purpose of closing the feeding window on the sampling capsule; the handle of the shell and the sampling rod can conveniently rotate the shell or the sampling rod to achieve the purpose of closing the strip sampling window after taking the material. The sampling rod is inserted into the sampler shell, and the angle between the rotating handle of the sampler shell and the rotating handle of the sampling rod is adjusted to achieve complete closing and opening of the sampling window to avoid entering the sampling capsule. The material can be prevented from leaking out and from entering different layers of the material during the process of inserting or pulling out the sampler from the inner packaging; the sampling scraper is arranged along the axial direction of the outer shell, and the overall rotation of the device relies on the movement of the sampling scraper to force the material into the sampling capsule through the feed window, effectively overcoming the problem that some materials have poor fluidity and cannot fully enter the sampling capsule; the scale rulers with two corresponding scales can accurately read the layer depth position of the sample taken in the inner packaging material, and at the same time, refer to the scale ruler on the sampling rod to rotate the sampling capsule corresponding to the position where sampling is not required by 180 degrees, to ensure that the feed window of the sampling capsule at this position remains in a closed state, while the sampling capsule at the position where sampling is required remains in an open state, to ensure the accuracy of the sampling position; at the same time, the various components of the utility model are plug-in or card-mounted, and can be disassembled and cleaned in turn to achieve cleaning without dead ends and avoid cross contamination.
