Technical Field

[0001] This utility model belongs to the field of soil sampling, and in particular relates to a detection and sampling device for soil improvement. Background Technology

[0002] Soil improvement refers to a series of technical measures that utilize theories and technologies from multiple disciplines such as soil science, biology, and ecology to eliminate or prevent adverse factors that affect crop growth and cause soil degradation, improve soil properties, enhance soil fertility, and create favorable soil environmental conditions for crops.

[0003] Before soil improvement, soil samples need to be taken and the proportions of various elements in the soil are analyzed through experiments. Based on the test data, the technical solutions required for soil improvement are determined. In the current sampling device, after inserting the ring cutter into the soil, the soil needs to be manually cut around the outside of the blade with a soil trimming knife until the bottom of the blade is completely exposed. Then the ring cutter is pulled out. The operation is cumbersome and reduces sampling efficiency.

[0004] Therefore, a soil improvement testing and sampling device is needed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a soil improvement testing and sampling device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A soil amendment testing and sampling device includes a sampling component, an operating component, and a blocking component. The sampling component includes a sampling tube. The bottom of the sampling tube has several receiving cavities and several soil inlets. The soil inlets are connected to the receiving cavities. The top of the sampling tube has a through groove. The bottom of the sampling tube has a cutting blade. The middle part of the sampling tube has an annular groove.

[0008] The blocking component includes several baffles and several operating levers. The baffles are connected to the operating levers through connecting pipes. The baffles are located in the soil inlet and the receiving cavity.

[0009] In a further technical solution, the size of the receiving cavity is larger than the size of the soil inlet.

[0010] In a further technical solution, the operating component includes a threaded rod, which is threadedly connected inside the sampling cylinder. The bottom end of the threaded rod is connected to the cleaning plate, and the top end of the threaded rod is connected to the operating plate.

[0011] In a further technical solution, the cleaning plate overlaps inside the sampling cylinder, and the cleaning plate is positioned above the soil inlet.

[0012] In a further technical solution, the size of the baffle is the same as the size of the receiving cavity, and the size of the baffle is larger than the size of the soil inlet.

[0013] In a further technical solution, the connecting pipe is disposed in an annular groove, the operating rod is disposed in a through groove, and the through groove is arc-shaped.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, after the bottom of the sampling cylinder contacts the ground, the rotating operating rod drives the sampling cylinder to move downward and rotate. The cutting blade at the bottom of the sampling cylinder cuts the soil in contact with it, and the cut soil enters the sampling cylinder through the inlet under the pressure. When the sampling cylinder moves to a suitable depth, the operating rod is pushed to move in the through groove. The moving baffle cuts the soil in the inlet. When the moving baffle contacts the other side of the inlet, the baffle can block the inlet and effectively prevent soil from falling. The sampling cylinder can be taken out by pulling the operating part upward. The operation is convenient.

[0016] This invention features a reverse-push operating lever that moves a downward-moving cleaning plate to push the soil inside the sampling cylinder, allowing the soil sample to be smoothly discharged through the inlet. During this process, the moving cleaning plate can scrape and clean the soil adhering to the inner wall of the sampling cylinder, making the operation convenient.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] Example 1

[0028] like Figures 1-6 As shown, this utility model embodiment provides a soil improvement testing and sampling device, including a sampling component 1, an operating component 2, and a blocking component 3. The sampling component 1 includes a sampling tube 11. The bottom of the sampling tube 11 is provided with a plurality of receiving cavities 13 and a plurality of soil inlets 12. The size of the receiving cavities 13 is larger than the size of the soil inlets 12. The soil inlets 12 are connected to the receiving cavities 13. The top of the sampling tube 11 is provided with a through groove 14. The bottom of the sampling tube 11 is provided with a cutting blade 15. The middle part of the sampling tube 11 is provided with an annular groove 16.

[0029] The blocking component 3 includes several baffles 31 and several operating rods 33. The baffles 31 are connected to the operating rods 33 through connecting pipes 32. The baffles 31 are located in the soil inlet 12 and the receiving cavity 13. The size of the baffles 31 is the same as the size of the receiving cavity 13, and the size of the baffles 31 is larger than the size of the soil inlet 12. The connecting pipes 32 are located in the annular groove 16, and the operating rods 33 are located in the through groove 14. The through groove 14 is arc-shaped.

[0030] In this embodiment, one hand holds the sampling cylinder 11, and the other hand rotates the operating member 2 clockwise. The rotating operating rod 33 drives the cleaning plate 22 to move upward, so that the upward-moving cleaning plate 22 contacts the top of the sampling cylinder 11.

[0031] The sampling component 1 is moved by the operating component 2. When the bottom of the sampling cylinder 11 contacts the ground, the operating component 2 is pressed down and rotated clockwise. Then, the rotating operating lever 33 drives the sampling cylinder 11 to move downward and rotate. Because the bottom of the sampling cylinder 11 is conical, the sampling cylinder 11 can be smoothly inserted into the ground. The cutting blade 15 at the bottom of the sampling cylinder 11 cuts the soil in contact with it, and the cut soil enters the sampling cylinder 11 through the inlet 12 under the action of compression. When the sampling cylinder... After the 11 moves to a suitable depth, push the operating rod 33 to move in the through groove 14. The moving operating rod 33 drives the connecting pipe 32 to rotate in the annular groove 16. At the same time, the rotating connecting pipe 32 drives several baffles 31 to move out of the receiving cavity 13 and into the soil inlet 12. During this process, the moving baffles 31 cut the soil in the soil inlet 12. When the moving baffles 31 come into contact with the other side of the soil inlet 12, the baffles 31 can block the soil inlet 12.

[0032] When the operating plate 23 is pulled upward and rotated forward, the upward-moving operating plate 23 drives the sampling cylinder 11 to move upward through the threaded rod 21, so that the upward-moving sampling cylinder 11 can smoothly take out the soil sample collected inside. The operation is convenient, and the device can easily sample the improved soil.

[0033] Example 2

[0034] The difference between this embodiment and embodiment 1 is that the operating component 2 includes a threaded rod 21, which is threadedly connected to the sampling cylinder 11. The bottom end of the threaded rod 21 is connected to the cleaning plate 22, and the top end of the threaded rod 21 is connected to the operating plate 23. The cleaning plate 22 overlaps the sampling cylinder 11 and is located above the soil inlet 12.

[0035] In this embodiment, when it is necessary to remove the soil sample from the sampling cylinder 11, the operating rod 33 is pushed in the opposite direction. The moving operating rod 33 drives the baffle 31 to slowly move out of the receiving cavity 13 through the connecting pipe 32, so that the baffle 31 releases its obstruction of the soil inlet 12. At the same time, the operating plate 23 is reversed. The rotating operating plate 23 drives the cleaning plate 22 to move downward through the threaded rod 21. The downward moving cleaning plate 22 pushes the soil inside the sampling cylinder 11, so that the soil sample can be smoothly discharged through the soil inlet 12. In this process, the moving cleaning plate 22 can scrape and clean the soil sample attached to the inner wall of the sampling cylinder 11, making the operation convenient.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
