Description

Technical Field

[0001] This utility model relates to the field of tea testing technology, and in particular to a sampling device for detecting the perchlorate content in tea. Background Technology

[0002] Tea is a natural beverage made from the tender buds and leaves of the tea tree (Camellia sinensis), a plant of the Theaceae family, through specific processing techniques. The production process usually includes core steps such as picking, withering, fixing, rolling, fermentation, and drying. These processes change the physical properties and chemical composition of the fresh leaves, resulting in a wide variety of flavor characteristics. Current tea testing methods often involve taking samples from the tea pile before testing. However, because the quality of tea varies at different depths within the pile, the sample size is limited, and the lack of sampling at different depths limits the testing process and fails to meet sampling requirements. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sampling device for detecting perchlorate content in tea.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A sampling device for detecting perchlorate content in tea leaves includes a mounting base, a connecting cylinder fixedly mounted at the lower end of the mounting base, a threaded rod rotatably mounted inside the connecting cylinder, a lifting block threadedly connected to the threaded rod, an outer cylinder fixedly mounted at the lower end of the lifting block, an inner cylinder rotatably mounted inside the outer cylinder, a rotary motor fixedly mounted at the lower end of the lifting block, the output shaft of the rotary motor fixedly mounted on the inner cylinder, openings on both the outer and inner cylinders that match each other, and a layer-breaking component mounted on the outer cylinder.

[0005] Preferably, the layer-breaking assembly includes a layer-breaking drill rotatably mounted on an outer cylinder, a plurality of extension blocks fixedly mounted on the layer-breaking drill, a gear ring fixedly mounted on the plurality of extension blocks, a slot on the connecting cylinder, a connecting block slidably mounted in the slot, the connecting block being fixedly connected to a lifting block, a rotating shaft rotatably mounted on the connecting block, a spur gear fixedly mounted on the rotating shaft, the spur gear meshing with the gear ring, and a control mechanism for controlling the rotation of the spur gear and the threaded rod mounted on the connecting block.

[0006] Preferably, the control mechanism includes a second rotating shaft rotatably mounted on a connecting block, with bevel gears fixedly mounted on both the second rotating shaft and the first rotating shaft, the two bevel gears meshing with each other, a second spur gear fixedly mounted on the second rotating shaft, a rack fixedly mounted on the connecting cylinder, the second spur gear meshing with the rack, a rotating motor fixedly mounted on the mounting base, and the output shaft of the rotating motor fixedly mounted on a threaded rod.

[0007] Preferably, the slot is square-shaped and the connecting block is also square-shaped, and the slot matches the connecting block.

[0008] Preferably, a protective box is fixedly installed at the lower end of the lifting block, and the rotary motor is installed inside the protective box.

[0009] Preferably, the two extension blocks are jointly fixedly mounted with a limiting block, which is rotatably mounted on the outer cylinder.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. By rotating the threaded rod, the lifting block is driven to descend, which in turn drives the outer and inner cylinders to descend, allowing them to enter different depths of the tea pile. At the same time, by starting the rotary motor, the inner cylinder is driven to rotate, allowing tea samples to be taken at this depth. This enables the sampling and testing of tea at different depths, making the test results more comprehensive and reliable.

[0011] 2. Simultaneously, during the descent, the control mechanism can drive the toothed ring to rotate, which in turn drives the layer-breaking drill to rotate. Thus, during descent, the layer-breaking drill can break open the tea pile, making it easier for the outer cylinder to enter the deeper layers of the tea pile. Attached Figure Description

Detailed Implementation

[0014] Reference Figures 1-3 A sampling device for detecting perchlorate content in tea leaves, comprising: Mounting base 1, with a connecting cylinder 2 fixedly mounted at the lower end of mounting base 1, a threaded rod 3 rotatably mounted inside the connecting cylinder 2, a lifting block 4 threadedly connected to the threaded rod 3, an outer cylinder 5 fixedly mounted at the lower end of the lifting block 4, an inner cylinder 6 rotatably mounted inside the outer cylinder 5, a rotary motor 7 fixedly mounted at the lower end of the lifting block 4, and the output shaft of the rotary motor 7 fixedly mounted on the inner cylinder 6, with openings 8 on both the outer cylinder 5 and the inner cylinder 6, and the two openings 8 matching, and a layer-breaking component mounted on the outer cylinder 5; By rotating the threaded rod 3, the threaded lifting block 4 can be driven to descend. The lifting block 4 drives the outer cylinder 5, inner cylinder 6 and rotary motor 7 to descend simultaneously. After reaching the specified tea depth, the rotary motor 7 is started to drive the inner cylinder 6 to rotate, so that the opening 8 on the inner cylinder 6 corresponds to the opening 8 on the outer cylinder 5. At this time, the tea will enter the inner cylinder 6. Continue to rotate the inner cylinder 6 to misalign the opening 8 of the inner cylinder 6 and the outer cylinder 5, so that tea sampling work at different depths can be easily completed. The layer-breaking assembly includes a layer-breaking drill 9 rotatably mounted on the outer cylinder 5, multiple extension blocks 10 fixedly mounted on the layer-breaking drill 9, a gear ring 11 fixedly mounted on the multiple extension blocks 10, a slot on the connecting cylinder 2, a connecting block 12 slidably mounted in the slot, the connecting block 12 fixedly connected to the lifting block 4, a rotating shaft 1 rotatably mounted on the connecting block 12, a spur gear 13 fixedly mounted on the rotating shaft 1, the spur gear 13 meshing with the gear ring 11, and a control mechanism for controlling the rotation of the spur gear 13 and the threaded rod 3 mounted on the connecting block 12. During the descent of the lifting block 4, the control mechanism will drive the rotating shaft to rotate, which will drive the spur gear 13 fixedly connected to the rotating shaft to rotate, thus driving the meshing gear ring 11 to rotate, which in turn drives the extension block 10 and the layer-breaking drill 9 to rotate. Therefore, when the outer cylinder 5 descends, the layer-breaking drill 9 rotates and descends at the same time, and performs the tea pile layer-breaking work. The control mechanism includes a second rotating shaft rotatably mounted on the connecting block 12. Both the second rotating shaft and the first rotating shaft are fixedly mounted with bevel gears 14, which mesh with each other. A second spur gear 15 is fixedly mounted on the second rotating shaft. A rack 16 is fixedly mounted on the connecting cylinder 2, which meshes with the rack 16. A rotating motor 17 is fixedly mounted on the mounting base 1, and the output shaft of the rotating motor 17 is fixedly mounted on the threaded rod 3. Start the rotating motor 17 to make the threaded rod 3 rotate, which drives the lifting block 4 to descend. At this time, the spur gear 15 on the connecting block 12 rotates on the rack 16, thus driving the rotating shaft 2 to rotate, thereby driving the bevel gear 14 to rotate, causing the meshing bevel gear 14 to rotate, and driving the rotating shaft 1 to rotate. The slot is square-shaped and the connecting block 12 is also square-shaped. The slot and the connecting block 12 match. The square shape allows the connecting block 12 to move stably up and down within the slot. At the same time, the fixed installation of the connecting block 12 and the lifting block 4 limits the lifting block 4, preventing it from shaking during descent. A protective box is fixedly installed at the lower end of the lifting block 4. The rotary motor 7 is installed inside the protective box. The protective box prevents tea residue from entering the rotary motor 7 and protects the rotary motor 7. Two extension blocks 10 are fixedly installed with a limit block 18. The limit block 18 is rotatably installed on the outer cylinder 5. The limit block 18 ensures the rotational stability of the extension blocks 10 and prevents shaking.

[0015] In this invention, the working principle is as follows: Starting the rotary motor 17 rotates the threaded rod 3, which drives the threaded lifting block 4 to descend. The lifting block 4 then drives the outer cylinder 5, inner cylinder 6, and rotary motor 7 to descend simultaneously. After reaching the designated tea-sampling depth, starting the rotary motor 7 rotates the inner cylinder 6, aligning the opening 8 on the inner cylinder 6 with the opening 8 on the outer cylinder 5. At this point, the tea leaves will enter the inner cylinder 6. Continuing to rotate the inner cylinder 6 further misaligns the openings 8 of the inner cylinder 6 and outer cylinder 5, easily completing tea sampling at different depths. When the threaded rod 3 rotates, it drives the lifting block 4 to descend. At this time, the spur gear 15 on the connecting block 12 rotates on the rack 16, thus driving the rotating shaft 2 to rotate, which in turn drives the bevel gear 14 to rotate. This causes the meshing bevel gear 14 to rotate, which in turn drives the rotating shaft 1 to rotate. The rotation of the rotating shaft 1 drives the spur gear 13 to rotate, which in turn drives the meshing gear ring 11 to rotate. This, in turn, drives the extension block 10 and the layer-breaking drill 9 to rotate. Therefore, when the outer cylinder 5 descends, the layer-breaking drill 9 also rotates and descends simultaneously, performing the layer-breaking work on the tea pile.
