the clamping block (5014) is matched with the clamping groove (504), and the cover plate (501) of the detection mechanism is opened and closed with the clamping groove (504) through the clamping block (5014);
the external water pipe (4) is communicated with the first connecting water pipe (101) and the second connecting water pipe (106) mutually, and the water guide pipe (9) is communicated with the inside of the detection mechanism (5) through a U-shaped joint (8);
the method for detecting the drug residue on the surface of the agricultural product by using the detection equipment for the drug residue on the surface of the agricultural product comprises the following specific steps:
the method comprises the following steps: putting an agricultural product to be detected into the detection equipment main body (1) through the putting opening (3), enabling the agricultural product to be detected to fall into an arc-shaped groove (104) formed in the upper end of a cleaning bottom plate (103), then switching on a water source through an external water pipe (4), spraying clear water to the agricultural product to be detected by a first spray head (102) and a second spray head (107) under the conveying of a first connecting water pipe (101) and a second connecting water pipe (106) for cleaning, dissolving residual medicines on the surface of the agricultural product, enabling detection liquid obtained after dissolution to flow into a water guide pipe (9) under the guiding of a drainage plate (10) to be matched with a U-shaped connector (8) to flow into a detection mechanism (5) after passing through a filter screen (105) along the arc-shaped groove (104); the filter screen (105) arranged at the bottom of the cleaning bottom plate (103) filters impurities attached to agricultural products to prevent the water guide pipe (9) from being blocked, the interior of the detection equipment main body (1) is partitioned by the buffering anti-seepage plate (6), the buffering anti-seepage plate (6) has a buffering effect on the fallen agricultural products, the vibration generated by the agricultural products is weakened, and meanwhile, the detection liquid can be prevented from permeating to damage other parts in the detection equipment main body;
step two: the detection solution flowing into the detection mechanism (5) flows into the detection groove (5022) through the through hole (5023), and the solution in the detection groove (5022) reacts with the detection solution; wherein, a first sealing cover (5011) and a second sealing cover (5012) are arranged on the inner side surface of the detection mechanism cover plate (501), when the detection mechanism cover plate (501) is closed, the first sealing cover (5011) and the second sealing cover (5012) respectively cover the first strip-shaped detection groove (502) and the second strip-shaped detection groove (503), and are matched with the sealing strips (5013) arranged on the periphery of the inner side surface of the detection mechanism cover plate (501), so that the influence of external environmental factors on the reaction of the detection liquid and the dissolving liquid can be prevented, when the internal temperature of the detection mechanism (5) needs to be adjusted, the temperature adjusting plate (507) is pushed into the detection mechanism (5) through the matching of the sliding chute (506) and the sliding block (5010), the heating block (509) arranged at the bottom end of the temperature adjusting plate (507) heats the inside of the detection mechanism (5), thereby accelerating the reaction rate of the detection solution and the dissolving solution and leading the detection solution and the dissolving solution to fully react;
step three: the detection mechanism cover plate (501) is opened through the matching of the clamping block (5014) and the clamping groove (504), the temperature adjusting plate (507) is slid through the matching of the sliding block (5010) and the sliding groove (506), the color change of the liquid after reaction is observed, and the residual concentration of the medicine on the surface of the agricultural product is visually obtained through comparison with the color comparison strip (201), so that the detection is completed.
