Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0021] Example 1, referring to Figure 1-4 The first embodiment of this utility model provides a rapid food sampling device, including an insertion rod 1, a connecting block 2, and a cavity 3. The top of the insertion rod 1 is fixedly connected to the bottom of the connecting block 2, and the cavity 3 is opened in the inner cavity of the insertion rod 1. The cavity 3 has a movable hole 4 on its front side, and there are multiple movable holes 4. The inner cavity of the movable hole 4 is provided with a sampling component 5. The cavity 3 is movably connected to a rotating rod 6. The top of the rotating rod 6 passes through the cavity 3 and the connecting block 2 and extends to the top of the connecting block 2. The bottom of the rotating rod 6 is rotatably connected to the inner wall of the cavity 3 through a bearing seat. The rotating rod 6 is cut into multiple segments. A positioning component 7 is provided on the rear side of the rotating rod 6.

[0022] Specifically, after the insertion rod 1 is inserted into the wheat pile, it can sample wheat piles at different depths through multiple sampling elements 51 in the sampling component 5, while the positioning component 7 can position the sampling elements 51.

[0023] Furthermore, the inspector takes the quick sampling device 51 to the side of the wheat pile, then grips the connecting block 2 to insert the insertion rod 1 into the wheat pile. Subsequently, the pull rod 76 is pulled up to move the locking block 74 up in the adjustment groove 72. The movement of the locking block 74 will compress the spring 75.

[0024] Example 2, the second embodiment of this utility model, provides a rapid food sampling device. The sampling component 5 includes a sampling element 51, which is movably connected to the inner cavity of the movable hole 4. A travel groove 52, which works in conjunction with the sampling element 51, is provided on the side of the cavity 3 near the sampling element 51. The sampling element 51 is movably connected to the inner cavity of the travel groove 52. A storage groove 53 is provided in the inner cavity of the sampling element 51. An entry hole 54 is provided on the front side of the storage groove 53. A flipping structure 55 is movably connected to the inner cavity of the entry hole 54. The flipping structure 55 includes a baffle 551, which is movably connected to the inner cavity of the entry hole 54. Control rods 552 are fixedly connected to both the left and right sides of the baffle 551. A movable groove 553, which works in conjunction with the control rod 552, is provided on the side of the sampling element 51 near the control rod 552. The control rod 552 is located away from the baffle. A rotating block 554 is fixedly connected to one side of a plate 551 through a movable groove 553. A torsion spring 555 is sleeved on the surface of the control rod 552. The side of the torsion spring 555 near the inner wall of the movable groove 553 is fixedly connected to the inner wall of the movable groove 553. The side of the torsion spring 555 near the rotating block 554 is fixedly connected to the rotating block 554. A rotating plate 8 is rotatably connected to the rear side of the sampling component 51 via a rotating shaft. A limiting hole 9 is opened at the top of the rotating plate 8. A limiting rod 10 is movably connected to the inner cavity of the limiting hole 9. A mating plate 11 is fixedly connected to the top and bottom of the limiting rod 10. The mating plate 11 is fixedly connected to the rotating rod 6 near the rotating rod 6. An anti-detachment ring 12 is fixedly connected to the surface of the rotating rod 6. An anti-detachment groove 13 that cooperates with the anti-detachment ring 12 is opened on the side of the connecting block 2 near the anti-detachment ring 12. The anti-detachment ring 12 is movably connected to the inner cavity of the anti-detachment groove 13.

[0025] Specifically, by setting up sampling component 5, flipping structure 55, rotating plate 8, limiting hole 9, limiting rod 10, mating plate 11, anti-detachment ring 12 and anti-detachment groove 13, multiple sampling components 51 can be moved simultaneously by rotating rotating rod 6 in conjunction with multiple mating plates 11, limiting rod 10 and rotating plate 8. The storage groove 53 in the sampling component 51 can store wheat, while the baffle 551 in the flipping structure 55 can limit the collected wheat. The coordinated use of torsion spring 555, control rod 552 and flipping block 554 can prevent the baffle 551 from moving without reason.

[0026] Furthermore, after the card block 74 disengages from the card slot 14, the rotating rod 6 drives multiple mating plates 11 to rotate. The rotation of the mating plates 11 provides a limiting rod 10 to press against the rotating plate 8. The rotating plate 8 can then drive the sampling piece 51 to be inserted into the wheat pile. When the sampling piece 51 is pressed against the wheat, the baffle 551 will flip into the storage tank 53. The rotation of the baffle 551 will drive the control rod 552 and the flipping block 554 to rotate. Then the flipping block 554 will twist the torsion spring 555. At this time, the wheat at the corresponding position will enter the storage tank 53 through the inlet hole 54. Subsequently, the rotating rod 6 reverses and drives the sampling piece 51 back to its original position through the mating plates 11, the limiting rod 10 and the rotating plate 8.

[0027] Example 3, the second embodiment of this utility model, provides a rapid food sampling device. The positioning component 7 includes an L-shaped rod 71. The front side of the L-shaped rod 71 is fixedly connected to the rotating rod 6. An adjustment groove 72 is provided in the inner cavity of the L-shaped rod 71. An adjustment hole 73 is provided in the rear side of the adjustment groove 72. A locking block 74 is movably connected to the inner cavity of the adjustment groove 72. A spring 75 is fixedly connected to the top of the locking block 74. A pull rod 76 is fixedly connected to the rear side of the locking block 74. The rear side of the pull rod 76 passes through the adjustment hole 73 and extends to the outside of the L-shaped rod 71. A locking groove 14 is provided in the top of the connecting block 2, and there are multiple locking grooves 14. The bottom of the locking block 74 passes through the adjustment groove 72 and extends into the inner cavity of the locking groove 14.

[0028] Specifically, by setting the positioning component 7 and the slot 14, after the rotating rod 6 is rotated to the appropriate position, the slot 14 is inserted into the slot 14 by the locking block 74, which can position the rotating rod 6 and the sampling component 5. The pressure of the locking block 74 by the spring 75 makes it difficult for the locking block 74 to fall out in the slot 14.

[0029] Furthermore, when the rapid sampling component 51 is pulled out of the wheat pile and wheat needs to be removed from the sampling component 51 at different locations, the rotating rod 6 moves the sampling component 51 to the outside of the insertion rod 1 through the mating plate 11, the limiting rod 10 and the rotating plate 8. Then, the pull rod 76 is released, and the spring 75 undergoes elastic deformation, causing the locking block 74 to be inserted into the locking groove 14, which can fix the position of the rotating rod 6. Then, by pulling the groove on the front side of the baffle 551, the baffle 551 is rotated, and then the wheat can be poured out.

[0030] Working principle: The inspector takes the quick sampling component 51 to the wheat pile, then grips the connecting block 2 to insert the insertion rod 1 into the wheat pile. Next, pulling up the lever 76 causes the locking block 74 to rise within the adjusting groove 72. The movement of the locking block 74 compresses the spring 75. Once the locking block 74 disengages from the groove 14, rotating the rotating rod 6 causes multiple mating plates 11 to rotate. The rotation of the mating plates 11 provides a limiting rod 10 that compresses the rotating plate 8. The rotating plate 8 then inserts the sampling component 51 into the wheat pile. As the sampling component 51 is compressed against the wheat, the baffle 551 flips into the storage groove 53. The rotation of the baffle 551 causes the control lever 552 and the flipping block 554 to rotate. The flipping block 554 then twists the torsion spring 55. 5. At this time, the wheat at the corresponding position will enter the storage tank 53 through the inlet hole 54. Then, the rotating rod 6 will drive the sampling piece 51 back to its original position through the mating plate 11, the limiting rod 10 and the rotating plate 8. When the wheat in the sampling piece 51 at different positions needs to be taken out by pulling the quick sampling piece 51 out of the wheat pile, the rotating rod 6 will drive the sampling piece 51 to move to the outside of the insertion rod 1 through the mating plate 11, the limiting rod 10 and the rotating plate 8. Then, the pull rod 76 will be released, and the spring 75 will undergo elastic deformation to drive the locking block 74 to be inserted into the locking slot 14, which can fix the position of the rotating rod 6. Then, by pulling the groove on the front side of the baffle 551, the baffle 551 will be rotated, and then the wheat can be poured out.

[0031] In summary, the combination of sampling component 5 and positioning component 7 achieved the effect of sampling wheat at different depths of the wheat pile.
