[0025] Refer to Figures 1-5, An embodiment provided by the present utility model: A sampling device for agricultural soil detection, including a device plate 1. Both front and rear sides of the bottom end of the device plate 1 are fixedly connected with brackets 2. A controller is installed on the top of the device plate 1 to control various electric drive components of the present device. The bottom ends of the brackets 2 are fixedly connected with ground platforms 3. An installation plate 15 is fixedly connected to the rear side of the opposite ends of the ground platforms 3. A first motor 4 is fixedly connected to the middle of the top end of the device plate 1. The driving end of the first motor 4 penetrates the inner wall of the device plate 1 and is fixedly connected with a transmission rod 13. A connecting rod 7 is fixedly connected to the middle of the top end of the right ground platform 3. A transfer plate 8 is rotatably connected to the upper side of the outer wall of the connecting rod 7. A water tank 5 is fixedly connected to the right part of the rear side of the top end of the device plate 1. A water pump is installed inside the water tank 5.

[0026] Specifically, a sliding rod 23 is slidably connected to the middle of the inner wall of the installation plate 15. A connecting plate 22 is fixedly connected to the rear end of the sliding rod 23. A shovel plate 12 is fixedly connected to the front end of the sliding rod 23. A spring 24 is fixedly connected to the front end of the connecting plate 22 near the outer side of the sliding rod 23. The front end of the spring 24 is fixedly connected to the rear end of the installation plate 15 near the outer side of the sliding rod 23. Pushing the connecting plate 22 forward compresses the spring 24. At the same time, the sliding rod 23 slides forward and pushes the shovel plate 12 forward to push the floating soil on the soil surface to one side, avoiding the mixing of the floating soil on the surface with the soil sampled from the deep layer and affecting the test results. A transfer disk two 16 is fixedly connected to the bottom end of the transmission rod 13. A cylinder 9 is fixedly connected to the bottom end of the transfer disk two 16. A driving end of the cylinder 9 is fixedly connected with a transfer disk one 10. A sampling tube 11 is fixedly connected to the bottom end of the transfer disk one 10. Starting the cylinder 9 to push the transfer disk one 10 downward causes the bottom of the sampling tube 11 to be inserted into the soil. Then starting the first motor 4 makes the transmission rod 13 rotate, thereby driving the lower cylinder 9 and the sampling tube 11 to rotate through the transfer disk two 16 to sample the soil. An electric push rod 17 is fixedly connected to the top end of the inner wall of the sampling tube 11. A push disk 18 is slidably connected to the inner wall of the sampling tube 11. The top end of the push disk 18 is fixedly connected to the driving end of the electric push rod 17. Starting the cylinder 9 drives the sampling tube 11 to rise, and the soil stuck in the sampling tube 11 is taken out. Then starting the electric push rod 17 to push the push disk 18 downward makes the soil in the sampling tube 11 be pushed out.

[0027] Specifically, a cavity cylinder 14 is fixedly connected to the rear side of the top end of the adapter plate 8. A spray head 19 is fixedly connected to the upper side of the rear end of the cavity cylinder 14. A fixing frame 20 is fixedly connected to the front side of the top end of the cavity cylinder 14. A cleaning pad 21 is fixedly connected to the outer end of the fixing frame 20. A hose 6 is fixedly connected to the lower side of the right end of the water tank 5. The other end of the hose 6 penetrates through the upper side of the inner wall of the rear end of the cavity cylinder 14 and is fixedly connected to the input end of the spray head 19. There is a notch at the bottom of the cavity cylinder 14, and the hose 6 can pass through the notch and extend into the inner wall of the cavity cylinder 14. Rotate the adapter plate 8 so that the top of the cavity cylinder 14 is aligned with the sampling tube 11. Then start the cylinder 9 to push the sampling tube 11 downward to sleeve it outside the cavity cylinder 14, and the inner wall of the sampling tube 11 is in close contact with the surface of the cleaning pad 21. Then start the water pump built in the water tank 5 to convey the water in the water tank 5 along the hose 6 to the spray head 19 for spraying. Start the first motor 4 again to make the sampling tube 11 rotate, so that the water sprayed by the spray head 19 is evenly sprinkled on each side of the inner wall of the sampling tube 11. At the same time, the cleaning pad 21 wipes each side of the inner wall of the sampling tube 11 to clean the inside of the sampling tube 11, avoid soil residue in the sampling tube 11 from mixing with the subsequent sampled soil, and affect the measurement results.

[0028] Working principle: First, move this device to the position where soil sampling is required. Then push the connecting plate 22 forward to compress the spring 24. At the same time, the sliding rod 23 slides forward and pushes the shovel plate 12 forward to push the floating soil on the soil surface to one side, avoiding the floating soil on the surface from mixing with the soil sampled from the deep layer and affecting the detection results. Then start the cylinder 9 to push the first transfer disk 10 downward, causing the bottom of the sampling tube 11 to be inserted into the soil. Then start the first motor 4 to rotate the transmission rod 13, so as to drive the lower cylinder 9 and the sampling tube 11 to rotate through the second transfer disk 16 to sample the soil. Then start the cylinder 9 to drive the sampling tube 11 to rise, and the soil stuck in the sampling tube 11 is taken out. Then start the electric push rod 17 to push the push plate 18 downward, so that the soil in the sampling tube 11 is pushed out. When cleaning the inside of the sampling tube 11 subsequently, just rotate the adapter plate 8 so that the top of the cavity cylinder 14 is aligned with the sampling tube 11. Then start the cylinder 9 to push the sampling tube 11 downward to sleeve it outside the cavity cylinder 14, and the inner wall of the sampling tube 11 is in close contact with the surface of the cleaning pad 21. Then start the water pump built in the water tank 5 to convey the water in the water tank 5 along the hose 6 to the spray head 19 for spraying. Start the first motor 4 again to make the sampling tube 11 rotate, so that the water sprayed by the spray head 19 is evenly sprinkled on each side of the inner wall of the sampling tube 11. At the same time, the cleaning pad 21 wipes each side of the inner wall of the sampling tube 11 to clean the inside of the sampling tube 11, avoid soil residue in the sampling tube 11 from mixing with the subsequent sampled soil, and affect the measurement results.
