Description

Technical Field

[0001] This utility model relates to the field of food security, and in particular to a food security detection and sampling device. Background Technology

[0002] An existing patent (publication number: CN217638106U) discloses a sampling device for agricultural product safety testing, including a sampler body. A pressure ring is fixedly fitted onto the outer wall of the sampler body, and a blocking component is provided on one side of the pressure ring. The blocking component includes an adhesive ring fitted onto the sampler body, with a rubber ring inside the adhesive ring. A collar is fixedly connected to the inner wall of the rubber ring, and a retaining ring is fixedly connected to one end of the collar. A flexible pull strip is fixedly connected to one side wall of the retaining ring, with one end of the flexible pull strip passing through the collar and retaining ring. Barbs are fixedly connected to the outer wall of the flexible pull strip. However, the length of the "sampler body" in this device is fixed, making it impossible to adjust the sampling depth according to the actual height and volume of the grain pile. Furthermore, the moisture content, temperature, and other parameters of grain at different depths vary, easily leading to inaccurate sampling and testing data, thus posing a drawback to grain safety testing. Summary of the Invention

[0003] This invention addresses the aforementioned shortcomings of existing technologies by providing a grain safety testing sampling device that allows for adjustment of the grain sampling depth based on the actual height and volume of the grain pile and the requirements for grain safety testing. By sampling grain at different depths within the grain pile separately and integrating the grain safety testing data, the device improves the accuracy of grain safety testing. Furthermore, the device features convenient opening and closing control of the sampling trough, facilitating rapid extraction of samples from the grain pile and preventing scattering or displacement of samples during extraction, thereby enhancing the efficiency of grain safety testing sampling operations.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A grain safety testing sampling device includes an inner sampling tube, an outer sampling tube, a fixed tube, a gear ring, a gear disk, a control rod, and a mounting plate. The outer sampling tube has a spike at its outer end and sampling holes on both sides. The inner sampling tube is connected to the inner sampling tube, which has multiple sampling grooves and a control rod groove. A rotating block is located outside the inner sampling tube and is connected to the interior of a bearing. The outer sampling tube is connected to the fixed tube, which has slide rails on both sides. The outer sampling tube also has positioning blocks on both sides, which are adapted to the slide rails and slide within them. A fixing ring is connected to the inner end of the fixed tube, and the inner side of the fixing ring is fitted to the outer sampling tube. The mounting plate is connected to the outer end of the fixed tube.

[0006] The mounting plate of this utility model has a toothed ring groove, which is adapted to the toothed ring and connected to it. The outer side of the toothed ring is attached to the mounting plate, and the inner side of the toothed ring is attached to the fixing tube. The fixing tube is attached to the gear disk, and the gear disk meshes with the toothed ring. The toothed ring is connected to the gear disk, and the inner end of the gear disk has a threaded rod. The threaded rod is sequentially connected to the fixing tube, the positioning support block, and the fixing ring. The threaded rod is connected to the positioning support block by a thread. The mounting plate has pressure plates on both sides, which are attached to the gear disk. The gear disk has a shaft, which passes through the pressure plate and is connected to a secondary knob. The secondary knob is attached to the pressure plate.

[0007] The mounting plate of this utility model has a fastening sleeve on its outer side, which fits against the main knob. The main knob has a control rod that is adapted to the control rod groove. The control rod passes through the fastening sleeve, the mounting plate, and the fixing tube in sequence. The control rod is connected to the control rod groove, which has a control protrusion. The control rod has a control groove, which is adapted to the control groove. The control protrusion is connected to the control groove. Beneficial effects

[0008] This utility model features a gear ring that meshes with both sides of the gear discs, causing the gear ring, gear discs, and threaded rod to move in tandem when the secondary knob is rotated. The threaded rod is positioned by a threaded connection with a positioning block, causing the sampling outer tube to move linearly within the fixed tube when the threaded rod rotates. This allows for adjustment of the grain sampling depth based on the actual height and volume of the grain pile and the requirements for grain safety testing. By sampling grain at different depths within the grain pile separately and combining the grain safety testing data, the accuracy of grain safety testing is improved.

[0009] The sampling outer tube of this utility model has a spiked rod at the front end for quick insertion during sampling. Multiple sampling slots allow for separate sampling of grain at different depths, facilitating data analysis. A control lever, via a main knob, provides a control fulcrum for the inner sampling tube. Rotating the main knob drives the inner sampling tube to rotate synchronously within the outer sampling tube. When the inner sampling tube rotates to the point where the sampling slot and sampling hole align, the grain enters the sampling slot through the sampling hole for sampling. After sampling, rotating the main knob in the opposite direction completely misaligns the sampling slot and sampling hole, creating a closed storage space between the inner and outer sampling tubes. This allows for rapid extraction of the sample from the grain pile, preventing scattering or displacement during sample removal.

[0010] This invention allows for adjustment of the grain sampling depth based on the actual height and volume of the grain pile and the requirements for grain safety testing. By sampling grain at different depths within the grain pile separately and integrating the grain safety testing data, the accuracy of grain safety testing is improved. Furthermore, the sampling trough opening and closing control operation is convenient, facilitating the rapid extraction of samples from the grain pile and preventing scattering or displacement of samples during extraction, thereby improving the efficiency of grain safety testing sampling operations.

The bearing 26 is connected to the inside, and the sampling tube 03 is connected to the outside of the bearing 26. The sampling tube 03 is connected to the fixed tube 06. The fixed tube 06 has slides 12 on both sides, and the sampling tube 03 has positioning blocks 11 on both sides. The positioning blocks 11 are adapted to the slides 12 and are connected to the slides 12. The positioning blocks 11 slide within the slides 12. The inner end of the fixed tube 06 is connected to a fixing ring 07. The inner side of the fixing ring 07 is attached to the sampling tube 03. The outer end of the fixed tube 06 is connected to a mounting plate 23.

[0025] Example 2:

[0026] The mounting plate 23 of this utility model has a toothed ring groove 25, which is adapted to the toothed ring 08 and connected to the toothed ring 08. The outer side of the toothed ring 08 is attached to the mounting plate 23, and the inner side of the toothed ring 08 is attached to the fixing tube 06. The fixing tube 06 is attached to the gear disk 09, and the gear disk 09 meshes with the toothed ring 08. The toothed ring 08 is connected to the gear disk 09, and the inner end of the gear disk 09 has a threaded rod 10. The threaded rod 10 is sequentially connected to the fixing tube 06, the positioning support block 11, and the fixing ring 07. The threaded rod 10 is threadedly connected to the positioning support block 11. The mounting plate 23 has pressure plates 24 on both sides, which are attached to the gear disk 09. The gear disk 09 has a shaft 22, which passes through the pressure plate 24. Plate 24 and shaft 22 are connected to auxiliary knob 13. Auxiliary knob 13 is attached to pressure plate 24. Gear ring 08 is meshed with gear discs 09 on both sides. When auxiliary knob 13 is rotated, gear ring 08, gear discs 09 on both sides, and threaded rod 10 move together. Threaded rod 10 is positioned with positioning support block 11 through threads. When threaded rod 10 rotates, sampling outer tube 03 moves linearly within fixed tube 06. This allows the sampling depth to be adjusted according to the actual height and volume of the grain pile and the requirements of grain safety testing. By sampling grain at different depths within the grain pile separately, and combining the grain safety testing data, the accuracy of grain safety testing is improved.

[0027] Example 3:

[0028] The mounting plate 23 of this utility model has a fastening sleeve 15 on its outer side, which fits against the main knob 14. The main knob 14 has a control rod 19, which is adapted to the control rod groove 29. The control rod 19 passes through the fastening sleeve 15, the mounting plate 23, and the fixing tube 06 in sequence. The control rod 19 is connected to the control rod groove 29, which has a control protrusion 21. The control rod 19 also has a control groove 20, which is adapted to the control groove 20. The control protrusion 21 is connected to the control groove 20. The sampling outer tube 03 has a spike 05 at its front end, which facilitates quick insertion during sampling. The multiple sampling grooves 02 are used to separate grains at different depths. Sampling facilitates the identification and analysis of sampled data. The control lever 19 adds a control fulcrum for the sampling inner tube 01 through the main knob 14. By rotating the main knob 14, the sampling inner tube 01 is driven to rotate synchronously within the sampling outer tube 03. When the sampling inner tube 01 rotates to the position where the sampling slot 02 and the sampling hole 04 correspond, the grain enters the sampling slot 02 through the sampling hole 04 for sampling. After sampling is completed, by rotating the main knob 14 in the opposite direction, the positions of the sampling slot 02 and the sampling hole 04 are completely misaligned, resulting in a closed storage space between the sampling inner tube 01 and the sampling outer tube 03. This allows the sample to be quickly extracted from the grain pile, preventing it from scattering or shifting when it is taken out.

[0029] Example 4:

[0030] The fastening sleeve 15 of this utility model is externally connected to a fastening buckle 28. The fastening buckle 28 has a fastening plate 16 on its inner side. The fastening sleeve 15 has plate through holes 18 on both sides. The control rod 19 has a fastening groove 17. The fastening groove 17 and the plate through holes 18 are adapted to the fastening plate 16. The fastening plate 16 passes through the plate through holes 18 and is connected to the fastening groove 17. This device can adjust the grain sampling depth according to the actual height and volume of the grain pile and the grain safety testing requirements. By sampling grain at different depths in the grain pile separately and combining the grain safety testing data, the accuracy of grain safety testing is improved. At the same time, the opening and closing control operation of the sampling slot is convenient, making it easy to quickly extract the sample from the grain pile and preventing the sample from scattering or shifting when it is taken out, thus improving the efficiency of grain safety testing sampling operations.
