Description

Technical Field

[0001] This utility model belongs to the field of detection technology, specifically relating to a sample delivery device. Background Technology

[0002] Atomic absorption spectrometry (AAS) can determine a wide range of elements, with flame atomic absorption spectrometry reaching concentrations down to the order of 10⁻⁹ g / mL. Its hydride generator can perform trace element determinations of eight volatile elements, including mercury, arsenic, lead, selenium, tin, tellurium, antimony, and germanium. Due to its sensitivity, accuracy, and ease of use, AAS is now widely used for macro- and micro-trace element analysis in metallurgy, geology, mining, petroleum, light industry, agriculture, medicine, health, food, and environmental monitoring.

[0003] Patent CN221445850U discloses a sample delivery and cleaning device and a sample delivery and cleaning control system. When a test tube placed on a test tube holder needs to be tested, the rotating device rotates the rotating support, causing the test tube to move below the liquid suction tube of the spectrometer. The support lifting device drives the mounting support to move upward, so that the liquid suction tube of the spectrometer is inserted into the test tube. The spectrometer detects the liquid to be tested in the test tube. After the detection is completed, the support lifting device drives the mounting support to move downward, and the test tube leaves the liquid suction tube of the spectrometer.

[0004] However, the rotating support method of rotational transmission has limitations, which makes it difficult to position the spectrometer. If the spectrometer is far from the rotating support, the rotating support will occupy a large amount of space. Utility Model Content

[0005] The purpose of this invention is to provide a sample delivery device that can better position the spectrometer.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sample delivery device, comprising:

[0007] Sample base plate;

[0008] A conveying device, comprising a first conveying pulley, a second conveying pulley, a conveyor belt, and a conveying drive motor, wherein the first conveying pulley and the second conveying pulley are rotatably connected to the sample feeding base plate, the conveyor belt is connected between the first pulley and the second pulley, the conveying drive motor is fixed to the sample feeding base plate, and the shaft of the conveying drive motor is fixedly connected to the first conveying pulley.

[0009] A conveyor seat, which is fixed on the conveyor belt, and has an upward-facing test tube slot on the conveyor seat;

[0010] A lifting device, which is fixed to the sample delivery base plate;

[0011] A clamping device is mounted on the lifting device. The clamping device is used to clamp the test tube placed in the test tube slot. After the lifting device lifts the test tube, the spectrometer's suction tube is inserted into the lifted test tube.

[0012] Furthermore, multiple transmission seats are provided.

[0013] Furthermore, a cleaning tube is installed in the test tube slot of one of the conveying seats. The opening of the cleaning tube is provided with a water outlet ring groove, and the cleaning tube is provided with a water inlet groove. The water inlet groove is located inside the water outlet ring groove, and the bottom of the water outlet ring groove is lower than the opening of the water inlet groove. A cleaning bracket is fixed on the sample delivery base plate. A water inlet pipe and a water outlet pipe are fixed on the cleaning bracket. The liquid absorption tube of the spectrometer is also fixed on the cleaning bracket. After the lifting device lifts the cleaning tube, the lower ends of the water inlet pipe and the liquid absorption tube of the spectrometer are inserted into the water inlet groove, and the lower end of the water outlet pipe is inserted into the water outlet ring groove. The upper end of the water inlet pipe is connected to a water inlet pump, and the upper end of the water outlet pipe is connected to a water outlet pump.

[0014] Furthermore, the lifting device includes a lifting bracket and a lifting cylinder. The lifting bracket is fixed to the sample feeding base plate, the lifting cylinder is fixed to the lifting bracket, and the clamping device is fixed to the piston rod of the lifting cylinder.

[0015] Furthermore, the clamping device is configured as a clamping cylinder, and clamping plates are installed at the two output ends of the clamping cylinder.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) The sampling device places the test tube to be tested in the test tube slot of the conveyor seat. Then the conveyor drive motor drives the first conveyor pulley to drive the first conveyor pulley and the second conveyor pulley to drive the conveyor belt to rotate, thereby moving the test tube to the bottom of the spectrometer's suction tube. At this time, the lifting device drives the clamping device to move downward, and then the clamping device clamps the test tube. Then the lifting device drives the test tube to move upward, so that the spectrometer's suction tube is connected to the test tube, thereby allowing the liquid in the test tube to be detected. Since the first conveyor pulley, the second conveyor pulley and the conveyor belt are used, the position of the spectrometer can be better arranged. Even if the position of the sample delivery device is far from the spectrometer, the space occupied by the sampling device remains unchanged.

[0018] (2) The water pump draws pure water into the water tank through the water inlet pipe. When the water tank is full, it will overflow into the water outlet ring groove. At this time, the water pump draws the water out of the water outlet ring groove through the water outlet pipe. In this way, the water can keep flowing and will never overflow. The liquid suction tube of the spectrometer is always immersed in pure water and is not contaminated. Attached Figure Description

[0025] Please see Figures 1-4 This utility model provides a sample delivery device technical solution.

[0026] A sample delivery device 1, comprising:

[0027] Sample base plate 2;

[0028] The conveying device includes a first conveying pulley 3, a second conveying pulley 4, a conveying belt 5, and a conveying drive motor 6. The first conveying pulley 3 and the second conveying pulley 4 are rotatably connected to the sample feeding base plate 2. The conveying belt 5 is connected between the first pulley and the second pulley. The conveying drive motor 6 is fixed on the sample feeding base plate 2, and the rotating shaft of the conveying drive motor 6 is fixedly connected to the first conveying pulley 3.

[0029] Conveyor seat 7 is fixed on conveyor belt 5 and has test tube slot 8 with the opening facing upward.

[0030] The lifting device is fixed on the sample delivery base plate 2;

[0031] The clamping device is installed on the lifting device. The clamping device is used to clamp the test tube 22 placed in the test tube slot 8. After the lifting device lifts the test tube 22, the suction tube 10 of the spectrometer 9 is inserted into the lifted test tube 22.

[0032] The sampling device 21 places the test tube 22 to be tested into the test tube slot 8 of the conveyor seat 7. Then, the conveyor drive motor 6 drives the first conveyor pulley 3, which in turn drives the conveyor belt 5 to rotate, thereby moving the test tube 22 below the liquid absorption tube 10 of the spectrometer 9. At this time, the lifting device drives the clamping device to move downward, and then the clamping device picks up the test tube 22. Next, the lifting device moves the test tube 22 upward, so that the liquid absorption tube 10 of the spectrometer 9 is inserted into the test tube 22, thus allowing the liquid in the test tube 22 to be detected. Because of the conveying method using the first conveyor pulley 3, the second conveyor pulley 4, and the conveyor belt 5, the position of the spectrometer 9 can be better arranged. Even if the position of the sample delivery device 1 is far from the spectrometer 9, the space occupied by the sampling device 21 remains unchanged.

[0033] like Figure 3 As shown, multiple transfer seats 7 are provided, so that test tubes 22 to be tested can be placed in advance for testing.

[0034] like Figure 3 and Figure 4 As shown, a cleaning tube 11 is installed in the test tube slot 8 of one of the conveying seats 7. A water outlet ring groove 12 is provided at the opening of the cleaning tube 11. A water inlet groove 13 is provided on the cleaning tube 11. The water inlet groove 13 is located in the water outlet ring groove 12. The bottom of the water outlet ring groove 12 is lower than the opening of the water inlet groove 13. A cleaning bracket 14 is fixed on the sample delivery base plate 2. A water inlet pipe 15 and a water outlet pipe 16 are fixed on the cleaning bracket 14. The liquid suction tube 10 of the spectrometer 9 is also fixed on the cleaning bracket 14. After the lifting device lifts the cleaning tube 11, the lower ends of the water inlet pipe 15 and the liquid suction tube 10 of the spectrometer 9 are inserted into the water inlet groove 13. The lower end of the water outlet pipe 16 is inserted into the water outlet ring groove 12. The upper end of the water inlet pipe 15 is connected to the water inlet pump, and the upper end of the water outlet pipe 16 is connected to the water outlet pump.

[0035] When the spectrometer 9 is not working or waiting, the lifting device raises the cleaning tube 11, and the lower ends of the water inlet pipe 15 and the liquid suction tube 10 of the spectrometer 9 are connected to the water inlet tank 13. The water pump draws pure water into the water inlet tank 13 through the water inlet pipe 15. When the water inlet tank 13 is full, it will overflow into the water outlet ring groove 12. At this time, the water outlet pump draws the water out of the water outlet ring groove 12 through the water outlet pipe 16. In this way, the water can keep flowing and will never overflow. The liquid suction tube 10 of the spectrometer 9 is always immersed in pure water and is not contaminated.

[0036] like Figure 3As shown, the lifting device includes a lifting bracket 17 and a lifting cylinder 18. The lifting bracket 17 is fixed on the sample delivery base plate 2, and the lifting cylinder 18 is fixed on the lifting bracket 17. The clamping device is fixed on the piston rod of the lifting cylinder 18. The extension and retraction of the piston rod of the lifting cylinder 18 can drive the clamping device to move up and down, thereby driving the test tube 22 to move up and down.

[0037] The clamping device is configured as a clamping cylinder 19, and clamping plates 20 are installed on the two output ends of the clamping cylinder 19. The clamping cylinder 19 can drive the two clamping plates 20 to move in opposite directions, thereby clamping or releasing the test tube 22.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
