[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0037] Embodiment 1: Refer to Figures 1-6 As shown, a bamboo shoot quality inspection device includes a base plate 1, and a pesticide residue detector 2 is fixed on the base plate 1. The pesticide residue detector 2 selected in this embodiment is produced by Shandong Yuntang Intelligent Technology Co., Ltd., and the model is YT-SA03.

[0038] Two grooves are opened on the base plate 1 on one side of the pesticide residue detector 2, and a control colorimetric cuvette 3 and a sample colorimetric cuvette 4 are respectively inserted into the two grooves. A blind hole is opened on the base plate 1, and the lower end of the test tube 5 is inserted into the blind hole.

[0039] When detecting pesticide residues in bamboo shoots, direct detection can be carried out, which can prevent the test tube 5, the reference colorimetric dish, and the sample colorimetric dish 4 from tipping over.

[0040] On the bottom plate 1 on one side of the blind hole, a bracket 7 is fixed. The vertical part of the bracket 7 is fixed on the bottom plate 1, the straight part of the bracket 7 is located above the test tube 5, and a sampler is inserted on the straight part of the bracket 7.

[0041] The sampler includes a sampling tube 9 with an open lower end. A long groove 8 is formed on the straight part of the bracket 7. The sampling tube 9 passes through the long groove 8. A retaining ring 16 is fixed on the sampling tube 9, and the lower end of the retaining ring 16 contacts the upper end of the straight part of the bracket 7.

[0042] A sealing cap 10 is inserted at the lower end of the sampling tube 9. By setting the sealing cap 10, the lower end of the sampling tube 9 is blocked after sampling, and the sample can be prevented from being contaminated during the process of transferring the sample.

[0043] A chamfer is formed on the outer edge of the lower end of the sampling tube 9. By setting the chamfer, it is convenient for the sampling tube 9 to penetrate the bamboo shoot for sampling.

[0044] A cross knife 11 is fixed inside the lower end of the sampling tube 9. Four sampling cavities are formed between the cross knife 11 and the inner wall of the sampling tube 9. A cutting knife 12 is arranged in the sampling tube 9 above each sampling cavity. The lower ends of the cutting knife 12 and the cross knife 11 are both processed with cutting edges. After the cutting knife 12 enters the sampling cavity, the side of the cutting knife 12 away from the axis of the sampling tube 9 is in sliding contact with the inner edge of the sampling tube 9, and the side of the cutting knife 12 close to the axis of the sampling cavity is in sliding contact with the cross knife 11.

[0045] Push blocks 13 are fixed at the upper ends of the cutting knives 12. After the push blocks 13 and the cutting knives 12 move downward, the push blocks 13 can enter the sampling cavity below them. The four push blocks 13 are fixedly connected to a fixed disk 14. A push rod 15 is fixed at the upper end of the fixed disk 14. The push rod 15 passes through the upper end of the sampling tube 9 and is in sliding contact with the upper end of the sampling tube 9. The cross section of the push rod 15 is rectangular. The cooperation between the push rod 15 and the sampling tube 9 can prevent the push blocks 13 and the cutting knives 12 from rotating around the axis of the sampling tube 9 in the sampling tube 9, and can ensure the relative positions of the cutting knives 12 and the push blocks 13 and the cross knife 11.

[0046] When detecting pesticide residues in bamboo shoots, sampling is carried out in advance. Pull the push rod 15 to make the push blocks 13 and the cutting knives 12 located in the sampling tube 9 above the cross knife 11. Then remove the sealing cap 10 so that the lower end of the sampling tube 9 penetrates the bamboo shoot, and part of the bamboo shoot will enter the sampling cavity. Then separate the sampling tube 9 from the bamboo shoot and insert the lower end of the sampling tube 9 into the sealing cap 10.

[0047] Then make the sampling tube 9 pass through the long groove 8 of the straight part of the bracket 7, and make the retaining ring 16 contact the upper end of the straight part of the bracket 7 and make the sampling tube 9 correspond to the test tube 5.

[0048] Press the push rod 15 so that the cutter 12 moves downward. After the cutter 12 enters the sampling cavity, it can cut the sample in the sampling cavity. When the cutter 12 contacts the sealing cap 10, the cutter 12 completes the cutting of the sample in the sampling cavity. Then remove the sealing cap 10 from the sampling tube 9, continue to press the push rod 15 downward. After the push block 13 enters the sampling cavity, the push block 13 can push out the sample in the sampling cavity. After the sample is pushed out, it enters the test tube 5.

[0049] During detection, pour buffer solution into the test tube 5 containing the sample so that the buffer solution is fully mixed with the sample to form a test solution.

[0050] Prepare the control group: Add 2.5 mL of buffer solution to the first reaction flask. Then add 100 μL of enzyme solution and color reagent respectively, and mix well. After standing and reacting for 10 min, add 100 μL of substrate and shake well. Then pour the liquid in the first reaction flask into the control cuvette 3 and immediately put the control cuvette 3 into the measurement chamber channel of the pesticide residue detector 2. Press the <Control> key of the pesticide residue detector 2. After the display screen of the pesticide residue detector 2 delays for the set number of seconds, the measurement time starts to count down. After the timing is completed, the display screen of the pesticide residue detector 2 shows the control absorbance increment and prompts completion.

[0051] Prepare the test group: Transfer the test solution to the second reaction flask, and then add 100 μL of enzyme solution and color reagent to the second reaction flask respectively, and mix well. After standing and reacting for 10 min, add 100 μL of substrate and shake well. Then pour the liquid in the second reaction flask into the sample cuvette 4 and promptly put the sample cuvette 4 into the measurement chamber channel of the pesticide residue detector 2. Press the <Sample> key. After the display screen delays for the set number of seconds, the measurement time starts to count down. After the timing is completed, the display screen shows the sample absorbance increment and inhibition rate, and prompts qualified or exceeded standard.

[0052] Example 2: On the basis of Example 1, as shown in Figure 1 A vibrator 6 is fixed on the bottom of the blind hole.

[0053] By arranging the vibrator 6 at the bottom of the blind hole, when the buffer solution is poured into the test tube 5 containing the sample, the vibrator 6 can be started. The vibrator 6 can quickly mix the sample and the buffer solution to form a test solution.

[0054] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
