[0023] AsFigure 1 As shown, the grain sampling device provided by the embodiment comprises a handle 1, a sampling rod 2 and a protective sleeve 3.

[0024] The handle 1 is fixed to the left end of the sampling rod 2, the sampling rod 2 is tapered from large left to small right, and the right end is relatively sharp to facilitate insertion into the sample bag. The sampling rod 2 is a hollow structure, and a sample inlet 21 is formed on the sampling rod 2 to allow grain samples to enter the sampling rod 2. After the sampling rod 2 is inserted into the sample bag, the grain material in the sample bag falls through the sample inlet 21 and fills into the sampling rod 2, allowing sampling of a certain depth and range in the sample bag. At the same time, the protective sleeve 3 is telescopic and sleeved on the sampling rod 2, one end of the protective sleeve 3 is arranged on the proximal end of the sampling rod 2 or the handle 1, and the other end of the protective sleeve 3 is arranged in an open manner away from the proximal end of the sampling rod 2. When the sampling rod 2 is inserted into the sample bag, the protective sleeve 3 is retracted, which does not affect sampling. When the sampling rod 2 is removed, the protective sleeve 3 is extended to protect the sample in the sampling rod 2, preventing the lightweight from falling and flying, ensuring the accuracy of sampling, protecting the workers, reducing the influence of the external environment on the sampling operation and the sampled sample, being flexible and practical, efficient and convenient, having a small structure and a large effect, and having low improvement cost.

[0025] At the same time, in the embodiment, the right end of the protective sleeve 3 is arranged in a horn mouth structure, which does not affect the sampling of the sampling rod 2 and does not damage the sample bag. During sampling, the protective sleeve 3 can automatically slide and retract according to the depth of the sampling rod 2, and the horn mouth of the protective sleeve 3 is at the edge of the sample bag, which can gather the occasionally scattered grain without affecting the sampling and preventing the grain from falling down. The telescopic protective sleeve 3 can protect the lightweight part in the grain, such as impurities, from being blown away by the wind and wetted by the rain, thereby ensuring the authenticity, integrity and representativeness of the sample.

[0026] In order to facilitate telescopic sliding and ensure normal and efficient sampling, the protective sleeve 3 comprises a fixed sleeve 31, a connecting sleeve 32 and a movable sleeve 33 which are sequentially and slidably sleeved, and all of them can adopt a metal cylinder structure. The fixed sleeve 31 is fixed to the left end of the sampling rod 2, the left end of the connecting sleeve 32 is slidably sleeved outside the fixed sleeve 31, and the left end of the movable sleeve 33 is sleeved outside the connecting sleeve 32. When the connecting sleeve 32 slides to the right end of the fixed sleeve 31 and the movable sleeve 33 slides to the right end of the connecting sleeve 32, the protective sleeve 3 is completely sleeved outside the sampling rod 2, and the sampling rod 2 or the sample is protected. At the same time, the right end of the fixed sleeve 31 and the distal end of the connecting sleeve 32 are provided with anti-disengagement bosses 34 for preventing the connecting sleeve 32 and the movable sleeve 33 from disengaging, the anti-disengagement bosses 34 are arc-shaped, the inner walls of the connecting sleeve 32 and the movable sleeve 33 are provided with anti-disengagement sliding grooves which are in sliding cooperation with the anti-disengagement bosses 34, which facilitates sliding and retraction, is simple and convenient, and is efficient and practical.

[0027] Meanwhile, the detachable cover at the right end of the protective sleeve 3 is provided with a protective cover, which better protects the sample rod 2 and the sample. The left end of the protective sleeve 3 can be detachably mounted on the proximal end of the sample rod 2 or the handle 1, facilitating mounting and dismounting. The protective sleeve 3 can also be used as a sampling container, achieving multiple uses of one object. In addition, the handle 1 can be provided with a hollow structure and be in communication with the hollow structure of the sample rod 2. A sampling bag is detachably sleeved on the handle 1. After sampling, the handle 1 is rotated, and the sample in the sample rod 2 is directly poured into the sampling bag, facilitating operation and simplifying sampling work.

[0028] The sampling device has simple structure, convenient operation, flexibility and practicality, can guarantee the authenticity, integrity and representativeness of the sample, has small structure and large effect, and has low cost and wide application range.

[0029] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
