Description

Technical Field

[0001] This utility model relates to the field of environmental testing technology, and in particular to an environmental testing sample shaking device. Background Technology

[0002] Environmental monitoring uses modern technologies such as physics, chemistry, and biology to monitor, measure, and control air, soil, and water bodies that reflect environmental quality, thereby making a comprehensive evaluation of environmental quality. A crucial step in the environmental monitoring process is sampling. When water samples are involved, the collected samples need to be sent to the testing site for subsequent testing, processing, and analysis.

[0003] Currently, existing environmental testing sample shaking devices have the following shortcomings in use: the collected samples need to be distributed into multiple reagent tubes, and then the samples are tested and analyzed by the detection device. When the sample collection volume is large, shaking each reagent tube individually is a large workload. Therefore, an environmental testing sample shaking device is designed to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an environmental testing sample shaking device. This device solves the following deficiencies in the use of existing environmental testing sample shaking devices: although they can be fixed in environmental testing using a clamping mechanism, the clamped magnetic ring cannot move during processing, which forces personnel to repeatedly operate between winding and clamping, and also causes wear on the magnetic ring and coil, reducing the processing quality of the magnetic ring.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design an environmental testing sample shaking device, including a mounting base. Multiple mounting plates are fixedly connected to the upper surface of the mounting base. A positioning ring is connected between two of the mounting plates. A sample processing container is rotatably mounted on the inner side of the positioning ring. An expansion inlet is fixedly connected to the upper end of the sample processing container. A rotating shaft is rotatably connected to the inner side of the positioning ring. A pendulum is fixedly mounted in the middle of the rotating shaft. A stirring paddle is mounted on the bottom end of the pendulum. A base is fixedly connected to the bottom end of the sample processing container.

[0007] Preferably, two arc-shaped racks are fixedly connected to the bottom end of the base, and a rotating rod is rotatably mounted on the upper part of the mounting base. Gears are fixedly fitted on both sides of the rotating rod, and the two gears mesh with the arc-shaped racks respectively.

[0008] Preferably, a small electric actuator is fixedly mounted on the upper surface of the mounting base, and a rack plate is fixedly connected to the extended end of the small electric actuator, the rack plate meshing with one of the gears.

[0009] Preferably, a limiting groove is formed on the upper surface of the mounting base, a limiting slider is slidably installed on the inner side of the limiting groove, and a spring is provided on the inner side of the limiting groove to cooperate with the limiting slider.

[0010] Preferably, a connecting rod is rotatably connected to the upper surface of the limiting slider, and the connecting rod is rotatably connected to the base.

[0011] The environmental testing sample shaking device proposed in this utility model has the following advantages: After the small electric actuator operates, its extended end continuously extends and retracts, driving the rack plate to move back and forth. This causes the meshing gear to rotate reciprocally, further driving the rotating rod to follow suit. This, in turn, causes the rotating rod to rotate simultaneously with the gear on the other side, driving the arc-shaped rack to move. This, in turn, causes the base to swing on the positioning ring. During the swing, the connecting rod moves, causing the limiting slider to slide within the limiting groove. During this sliding, the spring is continuously compressed, which in turn causes the pendulum to continuously swing around the rotating axis under the swing of the sample processing bucket. This, in turn, causes the stirring paddle to continuously stir the sample within the sample processing bucket. This allows for uniform shaking of environmental testing samples during testing, avoiding cumbersome subsequent work and improving testing efficiency. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-4 An environmental testing sample shaking device includes a mounting base 18. Multiple mounting plates 4 are fixedly connected to the upper surface of the mounting base 18. A positioning ring 2 is connected between two mounting plates 4. A sample processing container 3 is rotatably mounted inside the positioning ring 2. An expansion inlet 1 is fixedly connected to the upper end of the sample processing container 3. A rotating shaft 15 is rotatably connected to the inner side of the positioning ring 2. A pendulum 14 is fixedly mounted in the middle of the rotating shaft 15. A stirring paddle 16 is mounted at the bottom end of the pendulum 14. A base 5 is fixedly connected to the bottom end of the sample processing container 3. Two arc-shaped racks 17 are fixedly connected to the bottom end of the base 5. A rotating rod 6 is rotatably mounted on the upper part of the mounting base 18. Gears 8 are fixedly mounted on both sides of the rotating rod 6. The two gears 8 mesh with the arc-shaped racks 17 respectively.

[0019] Specifically, a small electric actuator 7 is fixedly mounted on the upper surface of the mounting base 18. A rack plate 9 is fixedly connected to the extended end of the small electric actuator 7, and the rack plate 9 meshes with one of the gears 8. A limiting groove 10 is formed on the upper surface of the mounting base 18. A limiting slider 12 is slidably mounted on the inner side of the limiting groove 10. A spring 11 is provided on the inner side of the limiting groove 10 to cooperate with the limiting slider 12. A connecting rod 13 is rotatably connected to the upper surface of the limiting slider 12. The connecting rod 13 is rotatably connected to the base 5. After the environmental detection sample is collected, it is poured into the expansion inlet 1 and mixed with the liquid in the sample processing container 3. The switch of the small electric actuator 7 is turned on by the external controller. When the small electric actuator 7 is running, the extended end continuously extends and retracts. The moving rack plate 9 moves back and forth, causing the meshing gear 8 to rotate reciprocally, which in turn causes the rotating rod 6 to rotate, causing it to rotate simultaneously with the gear 8 on the other side, driving the arc rack 17 to move. This, in turn, causes the base 5 to swing on the positioning ring 2. During the swing, the connecting rod 13 moves, causing the limiting slider 12 to slide within the limiting groove 10. During the sliding, the spring 11 is continuously compressed, which in turn causes the pendulum 14 to swing continuously around the rotating shaft 15 under the swing of the sample processing tank 3. This causes the stirring paddle 16 to continuously stir the sample within the sample processing tank 3. This is beneficial for the environmental testing sample shaking device to ensure uniform shaking during environmental testing, avoiding cumbersome subsequent work and improving testing efficiency.

[0020] Working principle: When using this device, the user pours the collected environmental samples into the expansion inlet 1, which then enters the sample processing tank 3 and mixes with the liquid. The user turns on the switch of the small electric push rod 7 from the external controller. When the small electric push rod 7 is running, its extended end continuously extends and retracts, driving the rack plate 9 to move back and forth. This causes the meshing gear 8 to rotate reciprocally, further driving the rotating rod 6 to rotate as well. This causes the gear 8 on the other side to rotate simultaneously, driving the arc rack 17 to move. This, in turn, causes the base 5 to swing on the positioning ring 2. During the swing, the connecting rod 13 moves, causing the limiting slider 12 to slide within the limiting groove 10. During the sliding, the spring 11 is continuously compressed, which in turn causes the pendulum 14 to swing continuously around the rotating shaft 15 under the swing of the sample processing tank 3. This causes the stirring paddle 16 to continuously stir the sample in the sample processing tank 3, improving the sample shaking effect of the sample processing tank 3.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
