[0022] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0023] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0024] Reference Figure 1 and Figure 2 As shown, pesticide residue detection is a means of detecting the residues of harmful substances in agricultural products, which can ensure the safety of agricultural products during use. Most of the existing pesticide residue detection equipment require operators to extract the agricultural product detection solution externally during the pesticide residue detection process, which makes the detection solution easily affected by external factors, thereby directly leading to inaccurate detection results, and further affecting subsequent judgments. In order to solve this type of problem, a non-contact pesticide residue detection device is proposed, including a detection frame 1 and a detection chamber 11 opened in the detection frame 1, the detection chamber 11 is provided with a plurality of detection tubes 22, the detection tubes 22 are provided with a reaction chamber 221 for containing a buffer reagent, the detection frame 1 on the upper side of one of the detection tubes 22 is provided with a feeding port 12 for feeding agricultural product fragments, and the lower side of the detection tube 22 is provided with a transfer member 2, and the transfer member 2 includes A turntable 21 is rotated in the detection chamber 11, and a mounting groove 212 is provided in the turntable 21 for the detection tube 22 to be inserted into. A driving member for driving the turntable 21 to rotate is provided at the bottom of the turntable 21, and a stirring member 3 for stirring and mixing the buffer solution in the reaction chamber 221 is provided on the upper side of the turntable 21 at the side of the feed inlet 12; the detection of pesticide residues can be carried out in a relatively stable environment by the arrangement of the detection frame 1 and the detection chamber 11, and the purpose of orderly accommodating the buffer solution reagent and the test agricultural products in the reaction chamber 221 can be achieved by the matching arrangement of the feed inlet 12 and the detection tube 22, and the purpose of fully stirring and mixing the buffer solution reagent in the reaction chamber 221 can be achieved by the arrangement of the transfer member 2 and the stirring member 3, thereby achieving the purpose of avoiding contact between the detection solution and the outside, thereby affecting the detection result, and thus achieving the purpose of non-contact, making the detection result more accurate.

[0025] It should be noted that the agricultural product fragments fed from the feed port 12 need to be processed outside the detection equipment. It is necessary to ensure that the agricultural product fragments enter the buffer reagent and can fully contact the buffer reagent, so that the residual substances in the agricultural product are mixed with the buffer, which is convenient for subsequent detection.

[0026] Furthermore, after the above-mentioned agricultural product fragments are put into the reaction chamber 22, the turntable 21 starts to rotate, thereby driving the detection tube 22 to move until the detection tube 22 moves to the lower side of the stirring element 3. At this time, the turntable 21 stops rotating, and the stirring element 3 starts to operate to stir and mix the agricultural product fragments and buffer reagent in the reaction chamber 221.

[0027] Specifically, the structure of the stirring member 3 is as follows: the stirring member 3 includes a first telescopic cylinder 31 arranged on the top of the detection frame 1, the output end of the first telescopic cylinder 31 extends downward into the detection chamber 11, and the bottom of the first telescopic cylinder 31 is provided with a stirring blade 32 for extending into the reaction chamber 221; the stirring blade 32 is gradually deepened to ensure that the agricultural product fragments and the buffer solution reagent in the reaction chamber 221 are fully mixed, thereby ensuring that the detection result of the subsequent detection solution is more accurate.

[0028] It should also be noted that the stirring blade 32 is located on the trajectory of the circular rotation of the detection tube 22. The purpose of this arrangement is to ensure that the stirring blade 32 can extend into the reaction chamber 221 without causing damage to the detection tube 22.

[0029] It should be noted that in order to ensure that the extraction and detection of the above-mentioned detection solution can be carried out in an orderly manner, in the present embodiment, a detection member 4 is provided on one side of the detection chamber 11 for sliding up and down, and the detection member 4 includes a detection base 41 slidably provided in the detection chamber 11, and a detection channel 411 for accommodating the detection tube 22 is provided in the detection base 41, and a detection element 43 for detecting the reagent in the reaction chamber 221 is provided in the detection channel 411; by the setting that the detection base 41 slides up and down, it can be achieved that when the detection tube 22 rotates to the bottom of the detection base 41, the detection base 41 slides downward at this time to make the detection tube 22 gradually penetrate into the detection channel 411, and at the same time, the detection element 43 in the detection channel 411 extracts and detects the detection reagent in the detection tube 22, thereby achieving the purpose of detection.

[0030] In addition, the power source for the above-mentioned detection base 41 to slide up and down is: a second telescopic cylinder 42 for driving the detection base 41 to slide up and down is provided on the upper side of the detection base 41; the operation of the second telescopic cylinder 42 can achieve the purpose of making the detection base 41 slide up and down.

[0031] It is worth mentioning that the specific structure of the above-mentioned driving member is: the driving member includes a driving motor 23 arranged at the bottom of the turntable 21, and the driving motor 23 is arranged on the bottom wall of the detection chamber 11; through the operation of the driving motor 23, the turntable 21 can be rotated in a circle, thereby driving the detection tube 22 to rotate in an orderly manner.

[0032] Furthermore, in order to ensure the orderly rotation of the above-mentioned turntable 21, in this embodiment, a plurality of limit posts 211 are rotatably provided on the bottom surface of the turntable 21, and the limit posts 211 extend downward to the bottom of the detection chamber 11; the setting of the limit posts 211 can achieve relatively stable rotation of the turntable 21.

[0033] The above detection process does not require any human involvement, avoiding contact between operators and the detection process, thereby achieving the purpose of non-contact, and such a setting can ensure that the pesticide residue detection results are more accurate.

[0034] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation manner. Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
