Description

Technical Field

[0001] This utility model relates to the technical field of soil sample testing and sampling devices, and more specifically, it relates to a soil sample testing and sampling device. Background Technology

[0002] Under current technological conditions, traditional soil sampling devices present numerous operational inconveniences in practical use. Firstly, because soil sample collection often requires sampling at varying depths and locations, operators typically need to repeatedly sample the same area to obtain a sufficient sample volume. This repetitive operation not only significantly increases the time cost of on-site work but may also disturb the soil structure around the sampling point, affecting the accuracy of subsequent sampling data. Furthermore, existing equipment has low sampling efficiency, requiring a cumbersome cleaning procedure after each sampling before the next, which is particularly inconvenient in field operations and severely restricts the overall efficiency of soil testing.

[0003] Another prominent issue is the lack of modular design in existing sampling devices. Most current equipment uses a fixed sampling container design, which often requires specialized tools for disassembly, or even complete disassembly of the entire sampling device, when the container needs to be replaced or cleaned. This design not only increases operational complexity but also makes the equipment more susceptible to malfunction due to lost or damaged parts in harsh field environments. Furthermore, the fixed sampling container design limits the flexible switching between different container sizes, making it difficult to adapt to diverse sampling needs. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides a soil sample testing and sampling device to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a soil sample testing and sampling device, including a fixed frame, a replacement mechanism on the fixed frame, the replacement mechanism including a base plate, a sampling bucket, a positioning rod and a middle rod, the lower end of the fixed frame is fixedly installed with the base plate, the base plate is provided with multiple positioning holes at equal intervals, each positioning hole is respectively limited and installed with a positioning rod, the upper end of each positioning rod is respectively coaxially installed with a middle rod, the base plate is provided with multiple fixing plates, each fixing plate and the positioning hole are coaxially arranged, each fixing plate is provided with a fixing tube, the fixing tube is provided with multiple elastic plates at equal intervals, and the multiple elastic plates respectively abut against the side wall of the middle rod, the upper and lower ends of the multiple elastic plates are respectively installed with a bottom ring and a top ring.

[0006] The present invention is further configured such that a bottom groove is provided inside the fixed tube, and the bottom ring abuts against the bottom groove.

[0007] The present invention is further configured such that each of the fixed tubes is provided with an inner push tube that slides inside the tube, and the inner push tube abuts against the top ring.

[0008] The present invention is further configured such that a rotating tube is coaxially provided on the inner push tube, and a hexagonal block is provided on the outer wall of the rotating tube.

[0009] The present invention is further configured such that a threaded tube is coaxially provided at the lower end of the hexagonal block, and the threaded tube is threadedly connected to the outer wall of the fixed tube.

[0010] The present invention is further configured such that a pressure plate is coaxially provided on the threaded pipe, a receiving plate is coaxially provided on the fixed pipe, and a spring is provided between the pressure plate and the receiving plate.

[0011] The present invention is further configured such that two foot pedals are respectively provided at both ends of the fixed plate.

[0012] The present invention is further provided that the upper end of the fixing frame is provided with a handle.

[0013] Compared with the prior art, this utility model provides a soil sample testing and sampling device, which has the following beneficial effects: This soil sample testing and sampling device adopts a modular design, enabling rapid switching between different sized sampling containers through an innovative replacement mechanism. When changing the sampling container, simply insert the positioning rod at the bottom of the container into the positioning hole in the base plate; simultaneously, the middle rod will embed into the fixing tube. The fixing tube contains multiple elastic plates that apply uniform frictional force to the middle rod through elastic deformation, ensuring a stable installation of the sampling container and preventing loosening or detachment during sampling.

[0014] When the fixing strength of the sampling bucket needs to be adjusted, the deformation of the elastic plate can be adjusted by rotating the threaded tube. The downward pressure of the threaded tube causes the top ring to move downward, while the bottom ring is fixed in the bottom groove, forcing the elastic plate to contract towards the center, thereby increasing the clamping force on the middle rod. This adjustable fixing method is suitable for sampling buckets of different sizes and weights, improving the versatility and adaptability of the equipment.

[0015] This design significantly improves the efficiency of sampling bucket replacement, allowing the operation to be completed without the need for additional tools, making it particularly suitable for rapid sampling operations in complex field environments. At the same time, the cushioning effect of the elastic plate reduces mechanical wear and extends the equipment's lifespan.

[0016] The device employs a foot-operated sampling method, making it simple and labor-saving. During sampling, the sampling bucket is placed vertically on the soil surface, and then the foot pedal is stepped on, using the user's weight to apply stable downward pressure, allowing the sampling bucket to smoothly insert into the soil. This design avoids sampling deviations caused by uneven force in traditional manual sampling, improving sampling accuracy and consistency.

[0017] Furthermore, the handle design on the top of the mounting bracket facilitates stable control of the equipment by the operator, ensuring that the sampling bucket enters the soil vertically and preventing sample deformation or uneven sampling depth due to tilting. The entire sampling process requires no complicated operations and can be efficiently completed by a single person, making it particularly suitable for large-scale soil testing or frequent sampling applications.

The replacement mechanism includes a base plate 2, a sampling bucket 3, positioning rods 4, and intermediate rods 5. The base plate 2 is fixedly installed at the lower end of the fixed frame 1. Multiple positioning holes 6 are equally spaced on the base plate 2. A positioning rod 4 is installed in each positioning hole 6. An intermediate rod 5 is coaxially installed at the upper end of each positioning rod 4. Multiple fixing plates 7 are provided on the base plate 2.

The multiple elastic plates 9 abut against the side wall of the intermediate rod 5. The upper and lower ends of the multiple elastic plates 9 are respectively installed with... It has a bottom ring 20 and a top ring 21. A bottom groove 10 is opened in the fixed tube 8. The bottom ring 20 abuts in the bottom groove 10.

Since the fixing tube 8 is equipped with an elastic plate 9, the middle rod 5 will abut against the elastic plate 9. The friction force is applied by multiple elastic plates 9, thereby ensuring the fixation of the sampling bucket 3. When it is necessary to adjust the fixing force of the elastic plate 9, since the threaded tube 14 is threadedly connected to the fixing tube 8, it will drive the top ring 21 to press down. Since the bottom ring 20 is fixedly abutting against the bottom groove 10, it will drive the elastic plate 9 to contract towards the axis, thereby increasing the deformation and thus ensuring the increase of friction force.

Since the fixed tube 8 is equipped with an elastic plate 9, the middle rod 5 will abut against the elastic plate 9. The friction force is applied by multiple elastic plates 9, thereby ensuring the fixation of the sampling bucket 3. When it is necessary to adjust the fixing force of the elastic plate 9, since the threaded tube 14 is threadedly connected to the fixed tube 8, it will drive the top ring 21 to press down. Since the bottom ring 20 is fixedly abutting against the bottom groove 10, it will drive the elastic plate 9 to contract towards the axis, thereby increasing the deformation and thus ensuring the increase of friction.

[0027] When sampling is required, the sampling bucket 3 is pressed onto the soil, and then the foot is placed on the foot pedal 18. By applying pressure with the foot, the sampling bucket 3 is inserted into the soil, thus completing the sampling process.
