[0060] The present invention provides a convenient veterinary drug residue fluorescence quantitative detection device, and the specific working principle is as follows: during normal use, the device is first transferred to a specified position by a pulley and powered on, the device data is debugged through a control panel 10, samples and reagents are added to the inside of a processing tank 4, the internal crushing rod is driven to rotate by a stirring motor 7, and the crushing rod is used for stirring and crushing. After the mixing is completed, the tissue fluid is extracted by a pump body 9, and the filter screen 34 in the filter sleeve 35 can be filtered during the extraction. The pump body 9 transports the tissue fluid to the shunt tube 27 through an output pipe 8, and the tissue fluid enters the test tube 31, so as to obtain multiple groups of test samples, and then the extraction is stopped. The control panel 10 is used to control the xenon lamp to run for a specified time. At this time, the light shielding seat 25 is in a horizontal state, which does not affect the irradiation of the tissue fluid in the test tube 31 by the xenon lamp. After the irradiation is completed, the fluorescent substance in the tissue fluid emits light, and the servo motor 1 is operated. 3. The driving gear 11 rotates, thereby using the driven gear 12 to drive the rotating rod 37 to rotate, and the rotating rod 37 drives the shading seat 25 to rotate through the connecting piece 38 until the shading seat 25 is vertical. At this time, the test tube 31 is located inside the shading seat 25, and then the moving motor 17 is operated. The moving motor 17 drives the threaded rod 23 to rotate, and drives the baffle 19 to move through the moving frame 21 until the baffle 19 fits the shading seat 25, so as to separate each group of test tubes 31. At this time, the optical fiber probe 20 corresponding to the inner side of the baffle 19 is used to detect the fluorescence brightness and time emitted by the fluorescent substance in the corresponding test tube 31. Since the baffle 19 cooperates with the partition 36 and the shading seat 25 to separate each group of test tubes 31, the detection data of each optical fiber probe 20 does not affect each other, and the data is transmitted to the control panel 10 for display, so that quantitative and rapid detection can be achieved, ensuring the accuracy of the detection;

[0061] When the test tube 31 needs to be disassembled, the personnel opens the box cover 3 and rotates the fixing ring 30 in sequence. The fixing ring 30 moves downward, and the limit ring 32 also moves downward. At this time, the wedge block 29 moves outward under the action of the spring 40. The wedge block 29 drives the positioning rod 39 to move, and the positioning rod 39 is separated from the test tube 31. The personnel can remove the test tube 31 and operate in sequence for easy replacement. It should be noted that the electronic devices used in this technical solution are all existing products. The technical solution of this application has no special requirements and changes to the structure of the above-mentioned electronic devices. In the process of implementing this technical solution, the personnel in this field need to connect all electrical components in this case to their compatible power supplies through wires, and should select a suitable controller according to actual conditions to meet the control requirements. The specific connection and control sequence should refer to the working principle of this technical solution and the working sequence between the electrical components. The detailed connection means are well-known technologies in this field. This technical solution mainly introduces the working principle and process, and no longer explains the electrical control.
