Detailed implementation manner

[0023] The following will further describe in detail the specific implementation manners of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0024] As Figures 1 to 4 shown, the sampling device for refractory organic matter in soil of the present utility model is characterized in that it includes:

[0025] An assembly 1 and a transmission assembly. An installation member 2 is arranged in the inner cavity of the assembly 1. A sampling tube 3 is arranged at the through hole of the installation member 2. A sampling drill bit 4 is coaxially arranged at the bottom end of the sampling tube 3 through threads. The sampling tube 3 is arranged inside the shaft hole of the moving member 5. A threaded rod 6 is rotatably arranged in the mounting hole of the installation member 2. The threaded rod 6 is arranged inside the threaded hole of the moving member 5. The transmission assembly is arranged on the moving member 5 and is cooperatively connected with the sampling tube 3;

[0026] A driving assembly, which is arranged on the assembly 1 and is used to provide rotational power to the threaded rod 6 and the sampling tube 3 respectively; through the combined design of the sampling drill bit 4 and the sampling tube 3, it can more effectively enter the soil and extract the soil in the area, ensuring the integrity and representativeness of the sample. The sampling tube 3 and the sampling drill bit 4 connected by threads can be easily disassembled and assembled, facilitating the user to replace components or perform maintenance under different environmental conditions. The cooperation of the threaded rod 6 and the threaded hole of the moving member 5 makes the sampling process more stable and controllable, and can accurately adjust the sampling depth. The overall design is simple and compact, convenient to carry and operate on-site, especially suitable for sampling work under complex terrain conditions in the wild. The driving assembly can provide power to the threaded rod 6 and the sampling tube 3 at the same time, which not only ensures the power demand during sampling but also simplifies the operation steps of the device. This device is applicable to various types of soil, and can smoothly sample both soft and hard soils, improving the application range of the sampling device, with convenient operation and strong adaptability.

[0027] As Figures 1 to 4As shown, as a preferred solution, the transmission assembly includes a hollow shaft 7 disposed in the positioning hole of the moving member 5. An active gear 8 is coaxially disposed on the hollow shaft 7, and a driven gear 9 is coaxially disposed on the sampling tube 3. The driven gear 9 is meshed and drivingly connected to the active gear 8. The transmission assembly adopts a combined design of a hollow shaft 7, an active gear 8, and a driven gear 9. This gear meshing and driving method ensures that the sampling tube 3 can rotate stably under the action of the driving assembly, improving the accuracy and efficiency of the sampling process. Since the transmission assembly is directly connected to the sampling tube 3, when the driving assembly is started, the sampling action can be automatically completed without additional manual adjustment, greatly simplifying the operation process.

[0028] As Figures 1 to 4 shown, as a preferred solution, the driving assembly includes a fixing member 10 disposed at the top of the assembly member 1. A driving shaft 11 is rotatably disposed in the empty slot of the fixing member 10. The other end of the driving shaft 11 is rotatably disposed in the limiting hole of the mounting member 2. The driving shaft 11 is disposed in the polygonal inner hole of the hollow shaft 7. The driving shaft 11 is coaxially disposed at the output end of a servo motor 12. The servo motor 12 is disposed on the fixing member 10. The driving shaft 11 is connected to the threaded rod 6 through a conduction assembly. Moving handles 18 are symmetrically disposed at both ends of the fixing member 10 respectively. The driving assembly uses the servo motor 12 as a power source and transmits the power to the hollow shaft 7 and the threaded rod 6 through the driving shaft 11, ensuring precise control of the power during the sampling process, thereby improving the accuracy and efficiency of the sampling process. The connection of the polygonal inner hole between the driving shaft 11 and the hollow shaft 7 provides a reliable mechanical connection, ensuring the stability and reliability of power transmission, avoiding possible power loss or slipping during the sampling process, and the polygonal structure ensures that the transmission relationship remains unchanged after the connection position between the driving shaft 11 and the hollow shaft 7 is adjusted. The design of the fixing member 10 ensures the stable installation of the driving assembly, and the connection of both ends of the driving shaft 11 to the empty slot of the fixing member 10 and the limiting hole of the mounting member 2 guarantees the stability and durability of the entire driving system.

[0029] As Figures 1 to 4 shown, as a preferred solution, the conduction assembly includes an active sprocket 13 coaxially disposed on the driving shaft 11, a driven sprocket 14 coaxially disposed on the threaded rod 6, and a chain 15 meshed and installed between the driven sprocket 14 and the active sprocket 13. Through the cooperation of the active sprocket 13, the driven sprocket 14, and the chain 15, the conduction assembly can accurately distribute the power generated by the servo motor 12 to the threaded rod 6, ensuring the stable rotation of the threaded rod 6 during the sampling process, thereby providing upward or downward power to the sampling tube 3. The meshing of the chain 15 with the active sprocket 13 and the driven sprocket 14 guarantees the smoothness of power transmission, avoiding unevenness during power transmission, which helps to reduce power loss and makes the sampling process smoother.

[0030] As Figures 1 to 4As shown in the figure, as a preferred solution, a material discharging member 16 is arranged in the inner cavity of the sampling tube 3. A positioning member 17 is coaxially arranged on the material discharging member 16, and the positioning member 17 is fixedly arranged on the fixing member 10. The design of the material discharging member 16 enables the sample to be quickly withdrawn from the sampling tube 3 after sampling, improving the sampling efficiency and shortening the time required for a single sampling. Through the cooperation of the material discharging member 16 and the positioning member 17, the operator can easily control the entry and exit of the sample, simplifying the sample processing process and making the sampling work more convenient and fast. The positioning member 17 is fixedly arranged on the fixing member 10, ensuring the stability and positioning accuracy of the material discharging member 16 during use and avoiding the problem of the material discharging member shifting caused by vibration or other factors.

[0031] As Figures 1 to 4 shown in the figure, as a preferred solution, support feet 19 are arranged at the bottom end of the assembly member 1. A pedal member 20 is arranged on the support feet 19. When the sampling drill bit 4 is in the retracted state, it is located between the pedal member 20 and the assembly member 1. The design of the support feet 19 provides a stable support point for the sampling device, protecting the sampling drill bit 4 during the initial stage of sampling and in the non-working state to prevent damage caused by collision. The design of the pedal member 20 enables the operator to easily step on it with the foot to fix the position of the sampling device, especially in the case of single-person operation, improving the work efficiency. When the sampling drill bit 4 is in the retracted state and located between the pedal member 20 and the assembly member 1, it can effectively avoid damage caused by the sampling drill bit 4 accidentally touching the ground or other hard objects, extending the service life of the sampling drill bit.

[0032] As Figures 1 to 4 shown in the figure, as a preferred solution, a partition member 21 is spirally arranged inside the sampling drill bit 4, and the spiral direction of the partition member 21 is the same as the drilling rotation direction of the sampling drill bit 4. The design of the partition member 21 can guide the soil to be transported into the inner cavity of the sampling tube 3, reducing the backflow of the soil during the drilling process, thereby improving the sampling efficiency.

[0033] As Figures 1 to 4 shown in the figure, as a preferred solution, the working process is as follows:

[0034] Select a suitable sampling drill bit 4 according to the type of soil to be sampled, connect it to the sampling tube 3 by threads, place the sampling device on the soil surface to be sampled, and use the pedal member 20 to fix the sampling device to ensure its stability. Start the servo motor 12, and the motor drives the hollow shaft 7 to rotate through the drive shaft 11, thereby driving the driving gear 8 to rotate. The driving gear 8 meshes with the driven gear 9, so that the sampling tube 3 starts to rotate. The rotation of the screw rod 6 is controlled through the conduction component between the drive shaft 11 and the screw rod 6. The rotation of the screw rod 6 drives the moving member 5 to move up and down, thereby adjusting the insertion depth of the sampling tube 3. As the sampling tube 3 and the sampling drill bit 4 rotate and penetrate into the soil, the soil is introduced into the sampling tube 3. The design of the baffle member 21 helps to reduce soil backflow. When the predetermined sampling depth is reached, stop the operation of the servo motor 12, then pull out the sampling drill bit 4 from the soil by moving the handle, and then reverse the servo motor 12 to lift the sampling tube 3. During this process, use the discharging member 16 to push the sample out of the sampling tube 3.

[0035] For the sampling device for recalcitrant organic matter in soil of the present utility model, its installation method, connection method or setting method are all common mechanical methods, and any implementation that can achieve its beneficial effects is acceptable.

[0036] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
