Description

Technical Field

[0001] This application relates to the field of environmental monitoring technology, and in particular to a multi-point sampling device for environmental monitoring. Background Technology

[0002] In the field of environmental monitoring, sampling of environmental media such as soil and solid waste is a crucial step in obtaining test data. To ensure the accuracy and representativeness of the test results, it is often necessary to conduct multi-point sampling and then analyze samples from different locations.

[0003] Currently, existing environmental monitoring sampling devices have several shortcomings in multi-point sampling processes. Firstly, samples typically require manual sorting and packaging, which is not only inefficient but also prone to sample mixing and contamination during sorting, affecting the reliability of test results. Secondly, existing sampling devices struggle to effectively pre-process samples, such as crushing or stirring. For hard or agglomerated samples, direct sampling can lead to poor sample homogeneity, thus affecting subsequent analysis. Furthermore, existing multi-point sampling devices are structurally complex, inconvenient to operate, and have low automation levels in sampling and packaging, increasing the workload of operators. Utility Model Content

The output end of the first driving component passes through the top of the sorting hopper and is fixedly connected to a rotating shaft. The lower part and the upper part of the rotating shaft are respectively provided with a spiral auger and a stirring arc plate. The spiral auger is located inside the sampling cylinder, and the stirring arc plate is located inside the sorting hopper.

The first gear is connected to the second drive assembly, and the upper surface of the second gear is provided with a plurality of receiving cylinders evenly circumferentially along its axis.

[0008] Below the first and second feeding pipes, there is a corresponding receiving tray. The side wall of the receiving tray is evenly provided with multiple receiving grooves along its axis, and the receiving tray is driven to rotate by a third driving component. A guide bucket is installed below the receiving tray by a bracket.

[0009] Preferably, the bottom of the sampling tube extends beyond the lower surface of the base.

[0010] Preferably, multiple stirring arc plates are evenly arranged along the axis of the rotation shaft, and the side of the stirring arc plate away from the rotation shaft is in contact with the inner wall of the sorting hopper, and the bottom of the stirring arc plate is in contact with the bottom of the sorting hopper.

[0026] The top of the sampling cylinder 2 is coaxially welded or bolted to a connecting sorting hopper 3. The upper part of one side of the sorting hopper 3 is open to receive externally added samples or samples conveyed from the sampling cylinder. The top center of the sorting hopper 3 is fixedly mounted with a first drive assembly 4 by bolts. The first drive assembly 4 can be a servo motor, and its output end passes through the top of the sorting hopper 3 and is fixedly connected to a rotating shaft 5.

[0027] A spiral auger 6 is welded or bolted to the lower part of the rotating shaft 5. The spiral auger 6 is located inside the sampling cylinder 2. When rotating, it can transport the sample collected at the bottom of the sampling cylinder 2 upward to the sorting hopper 3. A stirring arc plate 7 is welded or bolted to the upper part of the rotating shaft 5. Two stirring arc plates 7 are evenly arranged along the axis of the rotating shaft 5. The side of the stirring arc plate 7 away from the rotating shaft 5 is in contact with the inner wall of the sorting hopper 3. The bottom of the stirring arc plate 7 is in contact with the bottom of the sorting hopper 3, which can fully stir the sample in the sorting hopper 3.

[0028] The bottom side of the sorting hopper 3 is provided with a first outlet 19 and a second outlet 20. Both the first outlet 19 and the second outlet 20 are embedded with filter screens 21. The first outlet 19 is connected to the bottom of a first discharge pipe 8, and the second outlet 20 is connected to the bottom of a second discharge pipe 9.

[0029] The upper surface of the base 1 is provided with a first gear 10 and a second gear 11 that mesh with each other. The first gear 10 and the second gear 11 are rotatably connected to the base 1 through a rotating shaft. The first gear 10 is connected to the second drive assembly 12. The second drive assembly 12 is fixed to the upper surface of the base 1 through a support. The second drive assembly 12 is a stepper motor. The upper surface of the second gear 11 is provided with 6 receiving cylinders 13 evenly circumferentially along its axis.

[0030] Below the first feeding pipe 8 and the second feeding pipe 9, there is a corresponding receiving tray 14.
