Description

Technical Field

[0001] The invention relates to the technical field of soil sampling, and in particular to a sampler used for preventing and controlling soil environmental pollution. Background Art

[0002] Sampling is a very critical step in soil environmental pollution prevention and control. Through sampling and analysis, we can understand the types, concentrations and distribution of pollutants in the soil of a specific area, thereby helping people to formulate effective prevention and control measures.

[0003] A Chinese invention patent with announcement number CN118776971B discloses a soil sampling device, which belongs to the field of testing technology. It mainly includes a mounting frame, a drill rod, a storage member, a locking group and a sampling tube. The drill rod is arranged at the bottom of the mounting frame, and the storage member is rotatably engaged with the mounting frame. The storage member is located above the drill rod. There are multiple sampling tubes, and multiple sampling tubes are stored on the storage member. The rotation of the storage member can make the sampling tubes on the storage member selectively align with the drill rod up and down. When the sampling tube and the drill rod are aligned up and down, the locking group can slide on the mounting frame and drive the sampling tube downward to insert into the drill rod and disengage from the storage member, or drive the sampling tube upward to disengage from the drill rod and enter the storage member.

[0004] The above patent samples soil through a sampling tube. When multiple sampling is performed at different locations, the residual soil or contaminants in the sampling tube may be mixed into the next soil sample, thereby affecting the accuracy of the test results. In order to ensure the accuracy of the test results, the sampling tube is cleaned after each sampling is completed. The current cleaning method is to use water, a brush and an appropriate disinfectant for cleaning. The entire operation is performed manually, and the process is relatively cumbersome.

Since the soil sample is filled in the sampling tube 10, the circular plate 17, the connecting rod 171 and the pushing block 18 are driven to move upward. Then the output shaft of the stepper motor 4 is controlled to rotate 90 degrees, driving the rotating shaft 5 and the circular plate 6 to rotate 90 degrees. The circular plate 6 drives the sampling tube 10 and the lifting plate 8 to rotate 90 degrees. The lifting plate 8 on the left side of the rotating shaft 5 will rotate out from the push-pull block 13 and rotate to the front side of the rotating shaft 5. At the same time, the lifting plate 8 on the rear side of the rotating shaft 5 will rotate into the push-pull block 13, and the telescopic rod of the hydraulic cylinder 14 is controlled to extend again, driving the push-pull block 13 and the slider 12 to move downward to continue sampling the soil. The downward movement of the slider 12 can drive the pushing plate 19 to move downward, and the pushing plate 19 will push the circular plate 17. The circular plate 17 moves downward, and the connecting rod 171 moves downward. The connecting rod 171 drives the pushing block 18 to move downward. The pushing block 18 pushes the soil sample in the sampling tube 10 to discharge the soil sample in the sampling tube 10. The staff can put the container under the sampling tube 10 to collect the soil sample. After the soil sampling is completed and all the soil samples are discharged, the telescopic rod of the hydraulic cylinder 14 is controlled to shorten again, and the push-pull block 13 and the slider 12 move upward. The slider 12 drives the push plate 19 to move upward, and then the output shaft of the stepper motor 4 is controlled to rotate 90 degrees again, driving the sampling tube 10 and the circular plate 17 to rotate 90 degrees. The circular plate 17 on the front side of the rotating shaft 5 will rotate into the groove 30 on the front side. At this time, the annular tube 24 is aligned with the arc opening 2 7, the telescopic rod of the control cylinder 28 is extended, driving the pulling frame 29 to move upward, the pulling frame 29 pulls the circular plate 17 to move upward, the circular plate 17 drives the connecting rod 171 and the pushing block 18 to move upward, lifts the pushing block 18, and makes the height of the pushing block 18 higher than the arc opening 27, the upward movement of the pulling frame 29 can also drive the pulling plate 35 to move upward, the pulling plate 35 will pull the contact plate 34 to move upward, the contact plate 34 drives the moving plate 32 and the wedge plate 33 to move upward, the wedge plate 33 will push the contact shaft 31, so that the contact shaft 31 moves toward the direction of the sampling tube 10, so that the slide plate 21 can move toward the direction of the sampling tube 10, the second spring 22 is compressed, the annular tube 24 and the nozzle 25 will also move toward the direction of the sampling tube 10,The annular tube 24 and the nozzle 25 will enter the interior of the sampling tube 10 through the arc-shaped opening 27. At this time, the staff closes the disinfectant tube 26 and opens the water pipe 23, and then connects the water pipe 23 to an external water source, and the water flows into the annular tube 24 through the water pipe 23, and finally the water is sprayed out from the nozzle 25. The upper nozzle 25 sprays water to the bottom of the pusher block 18 to rinse the bottom of the pusher block 18, and the lower nozzle 25 sprays water to the inside of the sampling tube 10 to rinse the inside of the sampling tube 10, and removes the residual at the bottom of the pusher block 18 and the inside of the sampling tube 10. Soil and pollutants are prevented from being affected by residual soil and pollutants and affecting the accuracy of the test results. The inside of the sampling tube 10 is cleaned automatically to reduce manual intervention and improve the efficiency of soil sampling. After flushing, the water pipe 23 is closed and the disinfectant pipe 26 is opened. Then the disinfectant pipe 26 is connected to the disinfectant and the disinfectant is sprayed to the bottom of the pushing block 18 and the inside of the sampling tube 10 to eliminate the pollutants more thoroughly. During flushing and disinfection, a container can be placed under the sampling tube 10 to collect dirty water and disinfectant to avoid dirty water. The water and disinfectant contaminate the soil.

The pulling frame 29 pulls the circular plate 17 downward. The circular plate 17 drives the connecting rod 171 and the pushing block 18 to move downward, and the pushing block 18 is moved back to its original position. Similarly, when the circular plate 17 rotates to the groove 30 at the rear side, the air pipe 36 and the nozzle 37 will enter the interior of the sampling tube 10 through the arc opening 27. The air pipe 36 is connected to a hot air blower, and hot air is ejected from the nozzle 37 through the air pipe 36 to the interior of the sampling tube 10, drying the interior of the sampling tube 10, quickly drying the moisture inside the sampling tube 10, avoiding oxidation reaction, and thus preventing the interior of the sampling tube 10 from rusting.

The water pipe 23 is connected to a water source, and water flows into the annular tube 24 through the water pipe 23. Finally, the water is sprayed out from the nozzle 25. The upper nozzle 25 sprays water to the bottom of the pushing block 18 to rinse the bottom of the pushing block 18. The lower nozzle 25 sprays water to the interior of the sampling tube 10 to rinse the interior of the sampling tube 10. After the rinsing is completed, the disinfectant pipe 26 is connected to a disinfectant to spray the disinfectant. To the bottom of the pushing block 18 and the inside of the sampling tube 10, the pollutants can be eliminated more thoroughly. After the disinfection is completed, the telescopic rod of the control cylinder 28 is shortened, the wedge plate 33 no longer pushes the contact shaft 31, and the annular tube 24 and the nozzle 25 are moved out from the inside of the sampling tube 10. Similarly, the air pipe 36 and the nozzle 37 will enter the inside of the sampling tube 10 through the arc opening 27, and the air pipe 36 will be connected to the hot air. The hot air is sprayed from the nozzle 37 through the air pipe 36 and sprayed into the inside of the sampling tube 10 to dry the inside of the sampling tube 10.
