The exhaust pipe 25 is externally connected to an exhaust gas treatment device to extract the odor emitted by the liquid inside the sample storage beaker 7.

[0023] A loading area 3 and a unloading area 4 are provided inside the test box 2. A conveyor belt 5 is provided at the loading area 3, and a drawer 6 is provided at the unloading area 4. Several sample storage beakers 7 are placed on the conveyor belt 5. Reagent bottles 8 to be tested are placed in the drawer 6. After adding reagents into the reagent bottles 8 to be tested, the staff can first pull out the drawer 6 and then take away the reagent bottles 8 to be tested for testing.

[0024] Two guide rails 9 are symmetrically fixed inside the test box 2 , a moving screw rod 10 is arranged between the two guide rails 9 , a moving seat 11 is arranged between the guide rails 9 and the moving screw rod 10 , and a transfer mechanism is arranged on the moving seat 11 .

[0025] The guide rail 9 and the moving screw rod 10 both pass through the moving seat 11, and the guide rail 9 and the moving seat 11 are slidably connected, the moving screw rod 10 and the moving seat 11 are threadedly connected, and a moving motor 12 is installed on one side of the test box 2. The output end of the moving motor 12 is connected to the moving screw rod 10 through a coupling. When the moving motor 12 is started, the moving seat 11 can move along the guide rail 9 driven by the moving screw rod 10 until the rubber-tipped dropper 14 moves to the bottom of the sample storage beaker 7.

[0026] The transfer mechanism includes a cylinder 13 and a rubber-tipped dropper 14. The cylinder 13 is installed at the bottom of the moving seat 11. A lifting platform 15 is fixed at the output end of the cylinder 13. Two groups of through grooves 16 are spaced apart on the lifting platform 15. A bidirectional screw rod 17 is movably arranged between the two groups of through grooves 16. Slide blocks 18 are slidably arranged in the two through grooves 16. The bidirectional screw rod 17 passes through the slide blocks 18, and the bidirectional screw rod 17 is threadedly connected to the slide blocks 18. A first clamping plate 19 is fixed on the two slide blocks 18. A second clamping plate 20 is arranged on one side of the first clamping plate 19. The bottom of the second clamping plate 20 is fixed on the lifting platform 15. Two limiting grooves 21 are penetrated on the lifting platform 15. The rubber-tipped dropper 14 is located inside the limiting groove 21. When in use, the rubber-tipped dropper 14 can be directly inserted into the limiting groove 21, which is convenient for replacement. In addition, by arranging two rubber-tipped droppers 14, the frequency of replacing the rubber-tipped dropper 14 by the staff can be reduced.

[0027] The limiting groove 21 is located between the first clamping plate 19 and the second clamping plate 20, a first bevel gear 22 is installed on the bidirectional screw rod 17, and a transfer motor 23 is installed on the lifting platform 15. A second bevel gear 24 is installed on the output end of the transfer motor 23, and the second bevel gear 24 is meshed with the first bevel gear 22. The rotating motor 23 is started. Under the transmission action of the first bevel gear 22 and the second bevel gear 24, the bidirectional screw rod 17 will rotate and drive the two sliders 18 to move in opposite directions. At this time, the first clamping plate 19 and the second clamping plate 20 are close to each other to squeeze the top of the rubber head dropper 14 and discharge the air inside the rubber head dropper 14. Finally, the cylinder 13 is started to drive the bottom of the rubber head dropper 14 to extend into the sample storage beaker 7. The rotating motor 23 is started to reverse, and the first clamping plate 19 and the second clamping plate 20 are away from each other. At this time, the liquid to be detected can be drawn into the inside of the rubber head dropper 14, and finally the rubber head dropper 14 is moved to just above the reagent bottle 8 to be detected to discharge the liquid into the inside of the reagent bottle 8 to be detected.

[0028] Working principle of the utility model: When the device is used, the staff can place the sample storage beaker 7 to be tested on the conveyor belt 5, and the conveyor belt 5 drives it to move to the bottom of the transfer mechanism. By starting the moving motor 12, the moving screw 10 can be driven to rotate. Under the drive of the moving screw 10, the moving seat 11 can move along the guide rail 9, so that the rubber head dropper 14 moves to the bottom of the sample storage beaker 7. Start the rotating motor 23, and under the transmission action of the first bevel gear 22 and the second bevel gear 24, the bidirectional screw 17 will rotate and drive the two sliders 18 to move in opposite directions. At this time, the first clamping plate 19 and the second clamping plate 20 are mutually The squeezing is completed close to the top of the rubber-tipped dropper 14 to discharge the air inside the rubber-tipped dropper 14, and finally the cylinder 13 is started to drive the bottom of the rubber-tipped dropper 14 to extend into the sample storage beaker 7. The rotating motor 23 is started to reverse and the liquid to be tested can be drawn into the rubber-tipped dropper 14. Finally, the rubber-tipped dropper 14 is moved to just above the reagent bottle 8 to be tested. The liquid can be discharged into the reagent bottle 8 to be tested in the same way as above. In summary, the device can ensure that during the test, the sampling work can be completed without the staff having close contact with the chemicals, and the sample storage beaker 7 can be driven to move by setting the transmission belt 5, so that the staff can put in and remove the sample storage beaker 7 conveniently.
