Description

Technical Field

[0001] This utility model relates to the field of tea production technology, and in particular to a device for detecting pesticide residues in organic tea cultivation. Background Technology

[0002] During the tea growing process, pesticides are usually sprayed to control pests, which can result in pesticide residues on the leaves. In order to improve the safety of consumers, it is necessary to collect tea leaf samples for pesticide residue testing.

[0003] Currently, in existing technologies for detecting pesticide residues in tea leaf samples, an organic solvent is poured into a beaker containing the leaf sample. The sample is then manually shaken to mix, and a certain amount of reaction reagent is added. Finally, a rapid pesticide residue test card is used to determine the pesticide residue status of the tea. However, since there are often many samples to be tested in tea gardens, manually shaking the organic solvent and leaf sample together is very laborious and prone to uneven mixing, which can affect the test results.

[0004] Therefore, this application provides a device for detecting pesticide residues in organic tea cultivation to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem to be solved by this invention is to provide an organic tea plantation pesticide residue detection device to solve the problem that manually shaking organic solvents and leaf samples is very laborious and easily leads to uneven mixing.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] The mixing mechanism includes a first fixed frame, which is fixed to the edge of the base. A rotatable rotating seat is provided on the first fixed frame. A mixing cylinder for mixing tea samples and organic solvents is fixed on the rotating seat. A discharge pipe for discharging liquid into the detection container is fitted at the bottom of the mixing cylinder.

[0009] The titration mechanism includes a second fixing frame, which is fixed to the edge of the base. A fixing seat is fixed to the top of the second fixing frame, and two reagent cylinders for holding reaction reagents are installed on the fixing seat. A burette for titrating the reaction reagents into the detection container is fixed to the bottom of the reagent cylinders.

[0010] Optionally, three detection containers are provided, and the upper surface of the base is evenly provided with grooves for the bottom of the detection containers to be inserted.

[0011] Optionally, a motor is fixed to the top outer side of the first fixed frame, and a drive wheel is fixed to the motor shaft. The drive wheel and the rotating seat are at the same horizontal height, and a transmission belt is sleeved between the drive wheel and the rotating seat to form a transmission engagement.

[0012] Optionally, a sealing cap is hinged to the top of the mixing cylinder.

[0013] Optionally, the bottom of the mixing cylinder is provided with a discharge hole that connects to the discharge pipe, and the top of the discharge pipe is provided with a first switch.

[0014] Optionally, the two reagent cartridges contain an enzyme inhibitor and a colorimetric reagent, respectively.

[0015] Optionally, the mounting base is provided with a second switch for controlling the titration of the burette.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects:

[0017] In the above scheme, thanks to the cooperation between the rotating seat and the mixing cylinder, the rotating seat can drive the mixing cylinder to rotate, so that the organic solvent and the blade sample in the mixing cylinder can be quickly and uniformly mixed, which is not only highly efficient, but also has a good mixing effect.

[0018] In the above scheme, thanks to the setting of the titration mechanism and the setting of multiple detection containers, different reaction reagents can be titrated on multiple detection containers by using two reagent cylinders in the titration mechanism, thereby improving the range of pesticide residue detection.

[0031] It is understood that the meanings of “on”, “above”, and “above” in this utility model should be interpreted in the broadest manner, such that “on” not only means “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” not only means “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0032] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings.

A rotatable placement platform 2 is installed in the middle of the upper end surface of the base 1. A plurality of detection containers 3 are arranged on the placement platform 2. In this embodiment, three detection containers 3 are provided, and the upper end surface of the base 1 is evenly provided with grooves for the bottom of the detection containers 3 to be inserted.

[0034] The edges of the base 1 are respectively provided with a mixing mechanism 4 and a titration mechanism 5 corresponding to the trajectory of the transfer process of the detection container 3.

[0035] The mixing mechanism 4 includes a first fixing frame 401, which is fixed to the edge of the base 1. A rotatable rotating seat 402 is provided on the first fixing frame 401. A mixing cylinder 403 for mixing tea samples and organic solvents is fixed on the rotating seat 402. A discharge pipe 405 for discharging liquid into the detection container 3 is fitted at the bottom of the mixing cylinder 403. The organic solvent can be, but is not limited to, acetonitrile or acetone.

[0036] Specifically, a motor 407 is fixed to the top outer side of the first fixed frame 401, and a drive wheel 408 is fixed to the shaft of the motor 407. The drive wheel 408 and the rotating seat 402 are located at the same horizontal height, and a transmission belt 409 is sleeved between the drive wheel 408 and the rotating seat 402 to form a transmission engagement, so that the motor 407 can drive the rotating seat 402 to drive the mixing drum 403 to rotate, thereby achieving rapid mixing.

[0037] In addition, in this embodiment, a sealing cover 404 is hinged to the top of the mixing cylinder 403, and a discharge hole that connects with the discharge pipe 405 is provided at the bottom of the mixing cylinder 403. A first switch 406 is provided at the top of the discharge pipe 405, and the first switch 406 extends out of the first fixing frame 401 for convenient operation and control.

A second switch 505 for controlling the titration of the burette 504 is provided on the fixing seat 502. In specific implementation, the two reagent cylinders 503 respectively contain an enzyme inhibitor and a colorimetric reagent.

[0039] The working principle provided by this utility model is that, when in use, the rotating seat 402 can be driven to rotate by starting the motor 407, which in turn drives the mixing cylinder 403 to rotate, so that the organic solvent in the mixing cylinder 403 can be quickly and evenly mixed with the leaf sample. This not only has high efficiency, but also good mixing effect.

[0040] Then, the mixed liquid is poured into different detection containers 3 through the discharge pipe 405. Then, the two reagent cylinders 503 in the titration mechanism 5 are used to titrate different reaction reagents in multiple detection containers 3, thereby improving the range of pesticide residue detection.
