[0002] Food is the primary need of the people. If there are pesticide residues in the food production process, it will lead to food safety incidents. At present, there are many ways to detect pesticide residues in food: one is to directly wash the surface of the food and test the washing water, and the other is to crush the food to obtain its juice and test the pesticide residues in the juice.

[0003] The Chinese utility model patent with application number 202322046039.4 discloses a pesticide residue detection device. By setting a crushing device and an extrusion device, after the agricultural products are crushed by the crushing device, the flip plate is rotated to facilitate pouring the agricultural products into the extrusion device, and the juice is squeezed out under the action of the extrusion plate.

DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-4 The specific implementation modes of the present utility model are further described in detail.

[0022] The utility model is a food pesticide residue detection device, including a cleaning box 10, a crushing device 90 for crushing food is installed in the cleaning box 10, a horizontally arranged drain pipe 20 is arranged at the bottom of the cleaning box 10, a first valve 30 is installed in the drain pipe 20 and a detection tube 40 is coaxially connected, and a detection slot 50 is arranged at the top of the detection tube 40 along the length direction, the top of the detection slot 50 is open, and the width of the detection slot 50 is greater than the width of the detection test paper, so that the test paper is directly inserted into the bottom of the detection slot 50 and touches the liquid to be tested. In general, there is a max line on the test paper, and the max line cannot be exceeded when inserting the detection liquid. Controlling the depth of the detection slot 50 to 2-3cm also limits the maximum insertion depth of the test paper.

[0023] In addition, a base 11 is placed at the bottom of the cleaning box 10, and a PLC controller is fixedly installed on the base 11. A pressure sensor 13 is fixedly provided on the top of the base 11, and the pressure sensor 13 is connected to the PLC controller signal. The cleaning box 10 and the base 11 adopt a split design, and the cleaning box 10 can be taken out for separate cleaning. The setting of the pressure sensor 13 is convenient for obtaining the weight of the food in the cleaning box 10, thereby facilitating the inspection personnel to add appropriate distilled water to the cleaning box 10 according to the weight of the food.

[0024] In some embodiments, a water inlet pump 16 is fixedly installed on the side of the cleaning box 10, and the water inlet pump 16 is connected to the PLC controller signal. The pressure sensor 13 obtains the weight of the food and sends it to the PLC controller, which controls the water inlet pump 16 to automatically pump water into the cleaning box 10.

[0025] When in use, put the food into the cleaning box 10, then add distilled water for cleaning. After cleaning, open the first valve 30, and close the first valve 30 when the water does not exceed the mouth of the detection slot 50. In this way, the cleaning water can be quickly distributed to multiple detection slots 50, which is convenient for inserting test strips for testing. After the test is completed, rotate the detection tube 40 so that the mouth of the detection slot 50 faces downward, and then use distilled water to clean the cleaning box 10. After the cleaning waste water enters the detection tube 40, it will be discharged downward from the mouth of the detection slot 50, thereby preventing pesticide residues in the pipeline. Since the crushing device 90 is set, when in use, the food can also be crushed by the crushing device 90 to obtain its juice, so that after the pesticide residue is detected once on the surface of the cleaned food, the juice obtained by the crushed food can be tested twice.

[0026] A waste water tank 12 is fixed to the side of the base 11 . The length of the waste water tank 12 is greater than the length of the detection tube 40 . When cleaning the pipeline, waste water can be discharged into the waste water tank 12 for collection.

[0027] A second valve 60 is provided between the top side of the detection tube 40 and the detection slot 50. Through the setting of the second valve 60, after food cleaning water is added to multiple detection slots 50, the second valve 60 is closed, so that the detection slots 50 can be independent of each other, thereby avoiding mutual interference when inserting test strips for detection.

[0028] The first valve 30 and the second valve 60 are both solenoid valves. When the first valve 30 is opened, the cleaning liquid of the food in the cleaning box 10 enters the detection tube 40. The second valve 60 is generally in a normally open state. When the test paper is inserted into the detection slot 50 for detection, the second valve 60 is closed to isolate the food cleaning liquid in the detection slot 50 from each other.

[0029] An ultrasonic generator 80 is installed on the top of the cleaning box 10 and a cover plate 13 is installed on the top of the cleaning box 10. The ultrasonic generator 80 is a common device in the cleaning field. Please refer to the Chinese utility model patent application number 202020977622.0 for a food pesticide residue detection device, which will not be described in detail here.

[0030] The cover plate 13 and the top of the cleaning box 10 may be connected by threads or by hinges.

[0031] A power mechanism 70 is provided on the side of the cleaning box 10 to drive the detection tube 40 to rotate 180 degrees.

[0032] In this embodiment, the power mechanism 70 includes a motor 71 fixed to the side of the cleaning box 10, a first gear 72 connected to the output shaft of the motor 71, and a second gear 73 fixed on the detection tube 40. The second gear 73 is meshed with the first gear 72. When in use, the external power supply of the motor 71 is turned on, and the output shaft of the motor 71 drives the first gear 72 to rotate, the first gear 72 drives the second gear 73 to rotate, and the second gear 73 drives the detection tube 40 to rotate, so that the mouth of the detection groove 50 is facing the wastewater groove 12, which is convenient for the wastewater to be directly discharged into the wastewater groove 12 when cleaning the pipeline, and due to the direction of the mouth of the detection groove 50, the cleaning water will also rinse the inner wall of the detection groove 50.

[0033] A sealing sleeve 14 is fixed to the side of the bottom of the cleaning box 10 , one end of the drain pipe 20 is fixedly connected to the sealing sleeve 14 , and the other end of the detection tube 40 is rotatably connected to the other end of the sealing sleeve 14 .

[0034] In addition, the PLC controller is provided with buttons that can control the opening and closing of the ultrasonic generator 80, the first valve 30, and the second valve 60.

[0035] In some embodiments, the crushing device 90 includes a motor 91 fixedly connected to the cleaning box 10 and a crushing blade 92 arranged on the output shaft of the motor 91, wherein the upper end of the motor 91 is fixed to the inner wall of the cleaning box 10 by a fixed bracket 93. After the surface of the cleaned food is tested for pesticide residues once, the crushing blade 92 can be driven by the motor 91 to rotate and crush the food to obtain the juice of the food for secondary testing.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
