[0002] The current pesticide residue detectors have poor cleaning capabilities after testing, resulting in samples from the previous test remaining in the detector, contaminating the current test samples and causing inaccurate test results.

[0003] For example, the prior art CN214844342U is a pesticide residue detector. The device can place the fruits and vegetables to be tested into a test box through a shredding component, and the fruits and vegetables can be shredded by a cutting roller. After being sprayed with clean water, the clean water and the fruit and vegetable juice can be mixed together, thereby avoiding manual pounding, greatly saving labor and increasing work efficiency.

[0004] The existing technology has the following problem: after the test, the cleaning ability is poor, resulting in the last test sample remaining in the detector, contaminating the current test sample, resulting in inaccurate test results.

[0005] Therefore, in view of this situation, there is an urgent need to design and produce a pesticide residue detector to meet the needs of practical use. Utility Model Content

[0012] Preferably, a second motor is installed inside the storage box, and an output end of the second motor is fixedly connected to a connecting plate with an L-shaped cross-section.

[0013] Preferably, one end of the connecting plate away from the second motor is fixedly connected to a roller, a support rod is installed on the lower side of the outer shell, and one end of the water pipe away from the water pump is connected to a spray port.

[0014] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0015] The pesticide residue detector drives the extrusion plate to move horizontally through the second telescopic rod, and then drives the extrusion plate to move vertically through the first telescopic rod, moves the extrusion plate to the inside of the water tank, starts the first motor to drive the threaded rod to rotate, and drives the cleaning brush to move up and down through the rotation of the threaded rod to clean the extrusion plate. The previous test material can be cleaned to avoid the previous test material affecting the test result this time, making the test result more accurate.

[0016] The pesticide residue detector drives the connecting plate to rotate through the second motor, drives the roller to rotate up and down, and drives the filter plate to move up and down through the up and down movement of the roller, so as to quickly filter the squeezed liquid and improve work efficiency.
