Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, specifically a food quality testing sampling device. Background Technology

[0002] During grain storage, processing, and quality testing, it is often necessary to sample and analyze grains in deep piles or those under certain internal pressure (such as high-moisture grains, fermented mash, and grains in compacted silos). Existing sampling devices mostly employ piercing tubes or spiral samplers, which obtain samples by inserting the tube into the grain pile and relying on the natural flow of grain particles or negative pressure suction. To ensure that grain from non-target areas does not prematurely enter during sampling, some devices have inlet holes in the tube wall, and the alignment and offset of the holes are controlled by the relative rotation of the inner and outer cylinders, thus controlling the opening and closing of the sampling channel.

[0003] However, the existing devices still have the following shortcomings in actual use: First, after the sampling hole is opened, the bending strength of the cylinder decreases significantly. Especially when inserted into a dense or poorly fluid grain pile, the inner sampling cylinder is prone to bending and deformation, which affects the sampling accuracy and the life of the device, making it unsuitable for use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a food quality testing and sampling device.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A food quality testing sampling device, comprising:

[0007] The sampling outer tube has a puncture section at one end;

[0008] The sampling inner cylinder is movably inserted into the interior of the sampling outer cylinder and can rotate relative to the sampling outer cylinder. The end of the sampling inner cylinder located outside the sampling outer cylinder is provided with a discharge port.

[0009] The hand-held part is located at the end of the outer sampling cylinder and the inner sampling cylinder away from the puncture part;

[0010] The outer hole is located on the periphery of the sampling outer cylinder;

[0011] The inner hole is formed on the periphery of the sampling inner cylinder;

[0012] The reinforcing block is fixed inside the sampling inner cylinder and located on the opposite side of the inner hole;

[0013] When the sampling inner cylinder is rotated by the hand-held part until the inner hole and the outer hole coincide, the reinforcing block rotates with the sampling inner cylinder to the opposite side of the inner hole to the feed. The thickness of the reinforcing block gradually decreases from the end near the puncture part to the discharge port to form a slope structure to assist in feeding.

[0014] Preferably, the side of the reinforcing block facing the inner hole has a smooth guide surface, and the thickness of the guide surface gradually decreases from the opposite side of the inner hole toward the inner hole.

[0015] Preferably, the reinforcing block extends axially along the sampling inner cylinder, and the ramp structure extends continuously from one end near the puncture portion to the discharge port.

[0016] Preferably, the reinforcing block is integrally formed with the inner wall of the sampling inner cylinder, and the maximum thickness of the slope structure is located on the opposite side of the inner hole, and the minimum thickness is located at the edge of the inner hole and the discharge port of the sampling inner cylinder.

[0017] Preferably, the handheld part includes a first handle and a second handle, the first handle is fixed to the outer wall of the sampling outer cylinder, the second handle is fixed to the end of the sampling inner cylinder away from the puncture part, and a limiting structure with a relative rotation of 180° is provided between the first handle and the second handle.

[0018] Preferably, both the outer hole and the inner hole are slot structures, and they are the same size.

[0019] Preferably, both the outer and inner holes are provided in multiples, and are distributed at intervals along the axial direction of the sampling outer cylinder and the sampling inner cylinder.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. By fixing reinforcing blocks on the inner side of the cylinder wall on the opposite side of the inner hole, the bending strength lost due to the opening is significantly compensated, preventing the sampling inner cylinder from bending and deforming during insertion or rotation, and improving the structural stability of the device under high-pressure food testing and other working conditions.

[0022] 2. By reinforcing the axially extending ramp structure of the block, the ramp gradually thins from the end near the puncture part towards the discharge port to form a smooth downhill slope, allowing the sample to automatically slide towards the discharge port under the action of gravity and the ramp, achieving smooth discharge. This is suitable for foods with poor flowability, effectively avoiding sample retention or blockage, and improving sampling efficiency. Attached Figure Description

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0033] Example

[0034] like Figure 1-7 As shown, a food quality testing sampling device includes a sampling outer cylinder 1 and a sampling inner cylinder 2. The front end of the sampling outer cylinder 1 ( Figure 1 The left side of the sampling outer cylinder 1 has a sharp piercing part for easy insertion into the food. Figure 1 The first handle of the hand-held part 3 is fixed on the outer wall of the middle right side. At least one external hole 4 is opened on the wall of the sampling outer cylinder 1. In this embodiment, multiple holes are preferably distributed at equal intervals along the axial direction of the cylinder.

[0035] The sampling inner cylinder 2 is a hollow cylinder, the outer diameter of which is adapted to the inner diameter of the sampling outer cylinder 1. It is movably inserted into the sampling outer cylinder 1, and the two can rotate relative to each other. The rear end of the sampling inner cylinder 2 extends out of the sampling outer cylinder 1 and is provided with a discharge port; a second handle of the hand-held part 3 is fixed at the discharge port. The cylinder wall of the sampling inner cylinder 2 has inner holes 5 that are the same number, position, and size as the outer holes 4.

[0036] Reinforcing block 6 structure: On the inner wall of the sampling inner cylinder 2, and on the circumferentially opposite side of each inner hole 5 (i.e., when the inner hole 5 is located on one side of the cylinder, the reinforcing block 6 is integrally set on the opposite side of the inner wall of the inner cylinder), a reinforcing block 6 extending axially is fixed. In this embodiment, the reinforcing block 6 is integrally formed with the inner wall of the sampling inner cylinder 2 and is made of food-grade stainless steel or high-strength plastic.

[0037] like Figure 4 and Figure 7 As shown, the reinforcing block 6 extends from one end near the puncture section (deep within the inner cylinder) all the way to the discharge port. Its key feature is that the thickness of the reinforcing block 6 gradually decreases from the end near the puncture section towards the discharge port, thus forming a smooth sloping structure. Simultaneously, the surface of the reinforcing block 6 facing inwards (i.e., towards the cylinder wall where the inner hole 5 is located) is also a smooth curved surface. This surface gradually decreases in thickness from the opposite side of the inner hole 5 (i.e., the thickest part of the reinforcing block 6) towards the inner hole 5, forming a guiding surface. The sloping structure and the guiding surface achieve a smooth transition in space.

[0038] The maximum thickness of the ramp structure is located on the opposite side of the inner hole 5 (the furthest point inside the cylinder wall), and the minimum thickness is located at the edge of the inner hole 5 and the discharge port, which is close to zero.

[0039] A first limiting block is welded to the outer wall of the sampling outer cylinder 1, and a second limiting block (not shown in the figure) is welded to the sampling inner cylinder 2, which is snapped onto the outer wall of the sampling outer cylinder 1 and whose rotation path intersects with the first limiting block, thus limiting the sampling inner cylinder 2 to a specific angle, which is 180° in this embodiment.

[0040] Specifically: This device achieves sampling by relative rotation and orifice alignment between the sampling inner cylinder 2 and the sampling outer cylinder 1. The reinforcing block 6, its ramp structure, and guide surface enhance sample flow smoothness and cylinder strength. The specific working process is as follows: Initial state and insertion sampling; Before sampling, the first and second handles of the handheld part 3 are rotated relative to each other, completely misaligning the inner hole 5 of the sampling inner cylinder 2 with the outer hole 4 of the sampling outer cylinder 1 in the circumferential direction, thus closing the device. Then, the piercing part at the front end of the sampling outer cylinder 1 is inserted into the food to be tested to the required depth.

[0041] Sampling and Sample Entry: After reaching the predetermined depth, rotate the second handle of the handheld part 3 relative to each other, for example, 180° clockwise (limited by the first and second limiting blocks to ensure accurate rotation angle), until the inner hole 5 and the outer hole 4 are completely aligned, forming a sample entry channel. Under external pressure or its own gravity, the food to be tested passes through the outer hole 4 and the inner hole 5 and enters the internal cavity of the sampling inner cylinder 2.

[0042] At this time, the reinforcing block 6 located on the opposite side of the inner hole 5 plays two roles: guiding function: the guiding surface of the reinforcing block 6 facing the inner hole 5 is a smooth curved surface, which can smoothly guide the sample entering from the side wall to the middle of the sampling inner cylinder 2, avoiding the formation of turbulence or local accumulation.

[0043] Reinforcing function: The reinforcing block 6 is fixed to the inner side of the cylinder wall opposite the inner hole 5, which significantly compensates for the loss of bending strength due to the opening and prevents the sampling inner cylinder 2 from bending and deforming during insertion or rotation, especially in some high-pressure food testing.

[0044] Sample Discharge: During sample discharge, the sample flows towards the discharge port under the influence of gravity. The axially extending ramp structure of reinforcing block 6 gradually thins from the end near the puncture part (deep in the cylinder) towards the discharge port, forming a smooth downward slope. Under the action of gravity and the contact of the ramp, the sample automatically slides towards the discharge port along the ramp structure, achieving smooth discharge. This is especially suitable for foods with poor flowability, effectively avoiding sample retention or blockage and improving sampling efficiency.

[0045] Multiple sampling and reuse: The device can repeatedly perform the "rotate to open → sample injection → sample discharge" operation process. Multiple external holes 4 and internal holes 5, which are equidistantly distributed along the axial direction, can simultaneously inject samples, realizing multi-point synchronous sampling at different locations at the same depth, thus enhancing the representativeness of the samples.

[0046] In summary, this device controls the opening and closing of sampling by the relative rotation of the inner sampling cylinder 2 and the outer sampling cylinder 1. It has a simple structure and reliable sealing. The built-in reinforcing block 6 and its inclined structure and guide surface simultaneously realize the dual functions of anti-deformation support and streamlined flow / discharge, making it particularly suitable for the detection and sampling of deep or high-pressure foods.

[0047] The opening and closing control of the sampling channel is achieved by the relative rotation of the sampling inner cylinder 2 and the sampling outer cylinder 1, as well as the alignment and offset of the inner hole 5 and the outer hole 4. The structure is simple and the sealing is reliable, which can effectively prevent the sample from entering the device in advance when it is not being sampled.

[0048] By fixing reinforcing blocks 6 on the inner side of the cylinder wall opposite to the inner hole 5, the bending strength lost due to the opening is significantly compensated, preventing the sampling inner cylinder 2 from bending and deforming during insertion or rotation, and improving the structural stability of the device under high-pressure food testing and other working conditions.

[0049] By using the smooth curved guide surface of the reinforcing block 6 facing the inner hole 5, the sample entering from the side wall is smoothly guided to the middle of the sampling inner cylinder 2, avoiding turbulence or local accumulation, and improving the smoothness of sample injection.

[0050] By reinforcing the axially extending ramp structure of block 6, the ramp gradually thins from the end near the puncture site toward the discharge port to form a smooth downward slope, allowing the sample to automatically slide toward the discharge port under the action of gravity and the ramp, achieving smooth discharge. This is especially suitable for foods with poor flowability, effectively avoiding sample retention or blockage and improving sampling efficiency.

[0051] Other embodiments: In another embodiment, both the outer hole 4 and the inner hole 5 are elongated slots, each slot having a length of 1 / 6 of the cylinder circumference and a width of 5mm to ensure sufficient sample injection volume. The limiting structure of the handheld part 3 can also adopt a mechanical limiting structure with a combination of protrusions and grooves, or a spring plunger can be added to achieve a clear feel and positioning.

[0052] The slope of the ramp structure of reinforcing block 6 can be adjusted according to the characteristics of the sample. For example, the slope can be appropriately increased for samples with poor flowability (thickness changes more drastically).

[0053] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
