[0002] Food sampling is a method of extracting food before inspection. When sampling, attention should be paid to the dispersion of sampling points.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of the application are only for the purpose of describing specific embodiments and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0023] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] The present invention provides a food sampler for testing. Figure 1-4 As shown, it includes an insertion rod 1, a conical thorn 3 is welded to the bottom end of the insertion rod 1, and two handles 4 are symmetrically welded to the outer periphery of the other end of the insertion rod 1. The inner cavity of the insertion rod 1 is a hollow structure, and a through groove 2 is provided on the upper part of the outer periphery of the insertion rod 1, which penetrates to the lower part of the outer periphery of the insertion rod 1. Sliding grooves 5 are provided on both sides of the outer periphery of the insertion rod 1. The inner wall of the sliding groove 5 is slidably connected to a sliding block 11, and a sliding sampling box 8 is fixedly connected between the two aligned sliding blocks 11. A fixed sampling box 7 is fixedly connected to the end of the inner wall of the insertion rod 1 near the thorn 3. A limiting mechanism is installed on the bottom end of the inner wall of the sliding groove 5 and the inner wall of the sliding block 11. The limiting mechanism is used to limit the sliding sampling box 8 to the current position.

[0025] In this embodiment, when sampling granular food, the two sliding sampling boxes 8 are first pushed to move axially along the inner wall of the insertion rod 1, and the distance between one sliding sampling box 8 and the fixed sampling box 7 and the distance between the two sliding sampling boxes 8 are adjusted until the two distances are equal. During the sliding process of the two sliding sampling boxes 8, the force applied to the sliding sampling boxes 8 acts on the limiting mechanism. At this time, the limiting mechanism cannot realize the limiting function until the two sliding sampling boxes 8 are adjusted. At this time, the limiting mechanism limits the sliding sampling boxes 8 to the position after the movement without the action of external force.

[0026] The sliding of the two sliding sampling boxes 8 is based on the stacking width of the material. After the two sliding sampling boxes 8 slide, it should be realized that the fixed sampling box 7 and the two sliding sampling boxes 8 are located at the front, middle and rear positions in the width direction of the material during the insertion and sampling process of the device;

[0027] And in the process of inserting the insertion rod 1 into the material, the insertion rod 1 should keep the fixed sampling box 7 and the two sliding sampling boxes 8 in the lower position. Therefore, in the process of inserting the insertion rod 1 into the material, the material will not enter the fixed sampling box 7 and the two sliding sampling boxes 8 during the insertion process. Until the insertion is completed, the handle 4 is rotated by hand to rotate the device one hundred and eighty degrees. At this time, the openings of the fixed sampling box 7 and the two sliding sampling boxes 8 are facing upwards, and the material can fall into the fixed sampling box 7 and the two sliding sampling boxes 8 through the openings, thereby completing multi-point synchronous sampling.

[0028] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the limiting mechanism includes a plurality of ball grooves 6 provided at the bottom end of the inner wall of the sliding groove 5, and the plurality of ball grooves 6 are equidistantly distributed along the length direction of the insertion rod 1, and the limiting mechanism also includes a receiving groove 12 provided inside the sliding block 11, and the vertical cross-section of the receiving groove 12 is a "convex" structure rotated one hundred and eighty degrees, and the bottom end of the receiving groove 12 passes through to the bottom of the sliding block 11, and the limiting mechanism also includes a limiting block 14 slidably connected to the inner wall of the receiving groove 12, and the bottom end of the limiting block 14 passes through to the bottom of the sliding block 11, and the part of the limiting block 14 located outside the sliding block 11 is a hemispherical structure, and the inner wall of the ball groove 6 coincides with the outer wall of the hemispherical structure of the receiving groove 12, and the top of the limiting block 14 is fixedly connected to the spring 13, and the top of the spring 13 is fixedly connected to the top of the inner wall of the receiving groove 12.

[0029] In this embodiment, before inserting the insertion rod 1, when adjusting the positions of the two sliding sampling boxes 8, a thrust is applied to the sliding sampling box 8. At this time, the sliding sampling box 8 drives the two sliding blocks 11 to slide along the sliding groove 5. At this time, the sliding block 11 drives the limit block 14 to move. At this time, the hemispherical portion at the bottom end of the limit block 14 is squeezed against the inner wall of the ball groove 6. At this time, the limit block 14 moves upward along the inner wall of the accommodating groove 12. At this time, the spring 13 is compressed until the hemispherical portion of the limit block 14 completely enters the accommodating groove 12. When the limit block 14 is aligned with the ball groove 6 again, the compressed spring 13 pushes the limit block 14 to reset downward, so that the hemispherical portion of the limit block 14 is stuck in the ball groove 6 aligned with it.

[0030] The above-mentioned pushing method is used until the sliding sampling box 8 is pushed to the preset position.

[0031] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the top of the sliding sampling box 8 and the fixed sampling box 7 are integrally formed with an opening portion that is slidably connected to the upper through groove 2, and the two sliding sampling boxes 8 are integrally formed with an outwardly protruding connecting cone 9 at one end close to the thorn 3, and the cross-section of the connecting cone 9 is triangular.

[0032] In this embodiment, during the process of inserting the insertion rod 1 for sampling, the granular material will pass through the through slot 2 and stay between the fixed sampling box 7 and a sliding sampling box 8 and between a sliding sampling box 8 and another sliding sampling box 8, thereby forming a certain resistance. By providing a connecting cone 9, the pushing resistance can be reduced, avoiding the problem of excessive resistance causing the sliding sampling box 8 to move due to resistance.

[0033] In a further preferred embodiment of the present invention, Figure 1-4 As shown, a sampling opening mark 10 is engraved on the end of the insertion rod 1 away from the thorn 3, and the arrow direction of the sampling opening mark 10 is the same as the opening direction of the fixed sampling box 7 and the sliding sampling box 8.

[0034] In this embodiment, the sampling opening identification 10 enables the staff to quickly know the current orientation of the openings of the fixed sampling box 7 and the sliding sampling box 8, and can quickly discover any operational errors.
