[0002] Ancient tree Pu-erh tea is a special type of Pu-erh tea. The leaves of ancient tree tea are relatively larger than those of terrace-grown tea, with a distinct leathery texture, clear veins, irregularly serrated edges, and fewer hairs on the underside. Historically, traditional Pu-erh tea refers to tea made from large-leaf arbor tea trees from ancient Yunnan trees.

[0003] In the process of pesticide residue testing of ancient tree Pu'er tea, pesticide residue detectors are commonly used equipment. Before using the instrument, it is necessary to prepare solutions such as buffer solution, color reagent, and substrate. In specific operation, test tubes are used to prepare the solution. After the solution is prepared, it is put into the detector for testing. However, in the solution preparation stage, the testers need to manually shake multiple test tubes to mix the solutions in the test tubes, which undoubtedly increases the workload of the testers.

[0004] Therefore, it is necessary to provide a pesticide residue detection device for ancient tree Pu'er tea to solve the above-mentioned technical problems. Utility Model Content

The terms "first," "second," etc., in the specification or the foregoing drawings are used to distinguish different objects, not to describe a specific order; the terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This utility model embodiment provides a device for detecting pesticide residues in ancient tree Pu'er tea, such as... Figure 1-4As shown, the ancient tree Pu'er tea pesticide residue detection device includes: a base plate 1, on the top of which a pesticide residue detector body 2 for detecting pesticide residues in ancient tree Pu'er tea is fixedly installed; a screw 3 threaded onto the base plate 1, with a clamping plate 4 rotatably installed at the bottom end of the screw 3 for fixing the base plate 1 to a tabletop, a sliding rod 5 welded onto the clamping plate 4, and the sliding rod 5 slidably connected to the base plate 1; and a shaking mechanism assembled on the base plate 1 for mixing the pesticide residue detection solution.

[0023] In this embodiment, the device is first placed on a table, and then the screw 3 is rotated by hand. The screw 3 will drive the clamping plate 4 to move vertically, thereby allowing the base plate 1 and the clamping plate 4 to be effectively fixed on the table by bringing them closer together. In this way, even if the table is bumped, the device will not easily fall or move, ensuring the safety of the device during use. Then, the pesticide residue detection of ancient tree Pu'er tea can be carried out. Before the detection, the solution used for pesticide residue detection of ancient tree Pu'er tea needs to be prepared. During preparation, a certain number of test tubes are needed. Then, the solution to be prepared is put into multiple test tubes and then put into the shaking mechanism for mixing. This not only replaces manual mixing of the solutions in multiple test tubes, but also enables the shaking of multiple test tubes at the same time, eliminating the need to shake them one by one. This allows for faster and more labor-saving solution preparation. After preparation, the test tubes can be taken out, and then the pesticide residue detection of ancient tree Pu'er tea is carried out using these mixed solutions and the pesticide residue detector body 2. The pesticide residue detector body 2 is prior art, and its principle will not be described here.

[0024] In a further preferred embodiment of this utility model, the shaking mechanism includes: a box 6 fixedly installed on the top of the base plate 1, a frame 7 fixedly installed on the top of the box 6, and a plurality of tube sleeves 8 for placing test tubes rotatably installed on the frame 7; a plurality of springs 9 fixedly installed on the inner wall of the box 6, a common horizontal plate 10 fixedly installed on the plurality of springs 9, a plurality of elastic ropes 11 fixedly installed on the top of the horizontal plate 10, and the top ends of the plurality of elastic ropes 11 being fixedly connected to the bottom of the plurality of tube sleeves 8 respectively; two support blocks 12 welded to the bottom inner wall of the box 6, a support rod 13 slidably installed on each of the two support blocks 12, and the two support rods 13 being fixedly connected to the bottom of the horizontal plate 10; two push plates 14 fixedly installed on the two support rods 13 respectively; and a motor 15 fixedly installed on the bottom inner wall of the box 6, a cam 16 fixedly sleeved on the output shaft of the motor 15, the cam 16 being located on the side of the two push plates 14 that are close to each other.

[0025] In this embodiment, the shaking mechanism is used to mix the pesticide residue detection solution. During use, multiple test tubes containing the solution are placed into multiple tube sleeves 8, and then the motor 15 is started. After the motor 15 starts, its output shaft drives the cam 16 to rotate. Since the cam 16 is located on the side where the two push plates 14 are close to each other, as the cam 16 rotates, it periodically pushes the two push plates 14, thereby causing the support rod 13 and the horizontal plate 10 to reciprocate left and right under the elastic action of the spring 9. The reciprocating left and right movement of the horizontal plate 10 causes multiple elastic ropes 11 to drive multiple tube sleeves 8 to swing left and right in the frame 7, thus shaking the multiple test tubes and ensuring that the pesticide residue detection solution in the multiple test tubes is thoroughly and evenly mixed to meet the requirements of subsequent testing.

[0026] In a further preferred embodiment of the present invention, a plurality of anti-slip strips 17 are fixedly installed on the inner walls of the plurality of sleeves 8, and the plurality of anti-slip strips 17 are all made of rubber material.

[0027] In this embodiment, the use of anti-slip strip 17 can increase the friction between the sleeve 8 and the test tube, so that the inserted test tube will not come off the sleeve 8 during shaking.

[0028] In a further preferred embodiment of the present invention, a protective cover 18 is provided on the frame 7, and the protective cover 18 is used to cover multiple tube sleeves 8.

[0029] In this embodiment, the use of the protective cover 18 can prevent objects from entering the shaking mechanism in operation, and can also prevent inspectors from accidentally touching the shaking mechanism in operation.

[0030] In a further preferred embodiment of the present invention, a handle 19 is fixedly installed on the top of the protective cover 18, and the handle 19 is configured as an arc.

[0031] In this embodiment, the curved handle 19 allows personnel to easily remove the protective cover 18 from the frame 7 and also allows personnel to easily put the protective cover 18 back onto the frame 7.

[0032] In a further preferred embodiment of this utility model, an anti-slip pad is fixedly installed on the clamping plate 4, and a knob is fixedly installed on the top end of the screw 3.

[0033] In this embodiment, the use of anti-slip pads can increase the friction between the clamping plate 4 and the tabletop, thereby improving the clamping effect of the clamping plate 4 on the table.

[0034] In a further preferred embodiment of this utility model, all of the multiple springs 9 are made of stainless steel, and both of the two support rods 13 are L-shaped.

[0035] In this embodiment, the spring 9 made of stainless steel has good corrosion resistance and durability, making it suitable for long-term use.

[0036] In summary, compared with related technologies, this solution, through the use of screw 3, can move clamp 4 closer to or away from base plate 1, allowing clamp 4 to firmly fix the device to the tabletop. This ensures the device will not easily fall or move even if the table is bumped, guaranteeing its safety during use. The shaking mechanism replaces manual shaking of test tubes containing pesticide residue detection solution, enabling simultaneous shaking of multiple test tubes without individual shaking. This allows for faster and more labor-saving solution preparation, solving the technical problem of increased workload for testing personnel due to the need to manually shake multiple test tubes for solution preparation in the current pesticide residue detection process for ancient tree Pu'er tea. After solution preparation, the test tubes can be removed, and the prepared solution and pesticide residue detector body 2 can then be used to detect pesticide residues in ancient tree Pu'er tea.

[0037] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model.
